Investigation of Methods of Enhancing the Performance of Cyclone Separators in Gas Processes W. I. Mazyan Mechanical Engineering Department. Higher Colleges of Technology, Sharjah, UAE [email protected] Ahmadi School of Sustainable Design Engineering. University of Prince Edward Island, PEI, Canada J. Brinerhoff; M. Hoorfar Mechanical Engineering Department. University of British Columbia, BC, Canada H. Ahmed Chemical Engineering Department. American University of Sharjah, Sharjah, UAE This paper examines the feasibility of using novel and low cost techniques to increase the separation efficiency of cyclone separators numerically. Adding a tangential collecting chamber at the conical section of the cyclone separator was studied. The simulation results show that the tangential chamber enhances the separation efficiency for all particle ranges, especially small sized particles (i.e. 1, 2 and 3 micrometer). For 1 micrometer particle size, the efficiency was enhanced by 50%. The enhancement in the proposed model is due to the additional collecting chamber. Moreover, the accelerating particles at the conical section reach the outer walls and therefore, get collected by the tangential chamber. The goal of this study is to investigate the capturing efficiency enhancement in cyclone separators using additional tangential chambers.

Revealing structural and opto-electronic performance of photosensitive chalcopyrite CdAl2Se4: First-principle Modified Becke-Johnson (mBJ) observations Amit Soni, Department of Electrical Engineering Manipal University Jaipur Jaipur-303007, India [email protected] Jagrati Sahariya Department of Physics Manipal University Jaipur Jaipur-303007, India [email protected] Ushma Ahuja Department of Electrical Engineering NMIMS, Mukesh Patel School of Technology Management and Engineering Mumbai-400056, Maharashtra, India [email protected] Amit Soni (Manipal University, Jaipur, India); Jagrati Sahariya (Manipal University Jaipur, India); Ushma Ahuja (Mukesh Patel School of Technology Management and Engineering, India)

Present work mainly aims to explore possible utilization of photosensitive chalcopyrite CdAl2Se4 as potential material in optoelectronic applications. In view to ascertain that, we have performed first principle investigations within frame work of density functional theory (DFT) using full potential linearized augmented plane wave method (FP-LAPW). For better accuracy, volume optimization of lattice parameters and computations of relevant properties are executed using one of the most accurate modified Becke-Johnson (mBJ) potential. Electronic properties revealed are energy bands, total and partial density of states (DOS) which proves direct band gap (2.92 eV) nature for the present compound and supports its deployment in opto-electronic applications. In addition, in order to judge optical response, investigations such as dielectric tensor, reflectivity, refraction and absorption spectra are reported here as a function of frequency. Results observed showing high intensity of absorption spectra in visible energy range i.e. 3-5 eV validate the application of CdAl2Se4 in opto-electronic devices. Calculated results are observed to have reasonable agreement with available experimental calculations.

Sustainable Systems' Integration by means of STEP-NC; Literature Review Eng. Alaa M. Ubaid College of Engineering, University of Sharjah, Sharjah, UAE Email: [email protected] Dr. Fikri T. Dweiri College of Engineering, University of Sharjah, Sharjah, UAE Email: [email protected] Manufacturing systems is one of the main pillars of the global economy and there is a continuous efforts to make it more advanced, more sustainable, and more user-friendly. Toward this direction, the concept of computer-integrated manufacturing (CIM) invented. CAD-CAPP-CAM-CNC systems' integration considered as prerequisite for CIM to be exist. Data exchange format was one of the main systems' integration obstacles due to the lack of standardization, or in other words, lack of effective data exchange format. Therefore, ISO organization started STEP 10303(Standard for the Exchange of Product Data model) project in 1994 toward making a generic standard for data exchange on different levels. STEP-NC (or ISO 14649) was developed specifically for data exchange between CAD, CAM, CAPP, CNC and other corporate levels. Many researchers stated that STEP-NC format is the future solution to overcome all data exchange obstacles as it's provide a bi-directional information flow and offer the possibility of dynamic changes on the design models. However, researches to embed STEP-NC format within manufacturing systems still at the early stage. On the other hand, in last three decades the global warming theory reported and many researchers focused their efforts to study the sustainability concept and sustainable manufacturing term invented. The objective of this paper is proving the novelty of having an integrated system uses STEP-NC format for data exchange and in same time generating systems' plans by considering sustainability principles. 59 papers reviewed for the period between 2001 and 2017. Authors were able to prove the novelty of the aforementioned approach and many other research gaps were identifiable.

An innovative method for data transfer between Computer Aided Design / Manufacturing systems Laith Abdullah Al-Juboori Mechanical Engineering Division Higher Colleges of Technology Fujairah, UAE [email protected] Ahmed A. Duroobi Production & Metallurgy Engineering Dept. University of Technology Baghdad, Iraq [email protected] A new method for transfer data between Computer Aided Design/Manufacturing (CAD/CAM) programs has been presented in this work. Where, a program using MATLAB language has been built to transfer these data, and a procedure to convert curves to surfaces using UGS as a CAM environment without any distortion in their geometrical shape also has been presented, hence the matrix of n-degree of the Bezier and B-spline curves and surfaces had been derived to use it in the present work as a case study to test the proposed method and program. It has been observed during the implementation of the program using MATLAB and the simulation using UGS that this program can be used for transform any complex profile shape from CAD to CAM program without occur any distortion in the final shape of the profile in CAM program, and then it can be get the G-code for the any complex profile. The present method matched the experimental result conformity, also, it can be implement this method using the program that was built in the present work in short time if compared it to another method.

Analysis of the effect of Hole EDM parameters on MRR, Surface roughness and Micro hardness of Steel 304 Laith Abdullah Al-Juboori Mechanical Engineering Division Higher Colleges of Technology Fujairah, UAE [email protected] Shukry H. Aghdeab Production & Metallurgy Engineering Dept. University of Technology Baghdad, Iraq [email protected] Christina Apostolopoulou Mechanical Engineering Division Higher Colleges of Technology Fujairah, UAE [email protected]) Electrical Discharge Machining (EDM) is a non-traditional cutting process for metals removing based upon the fundamental fact that negligible tool force is generated during the machining process. Also, EDM is used in manufacturing very hard materials that are electrically conductive. In EDM process, the crucial objective parameters are Material Removal Rate (MRR), Surface Roughness (Ra) and Micro Hardness (HV). Conventional try and error method to determine the effect of machining parameters on the objective parameters is time consuming as well as high cost. The purpose of the present work is to develop a mathematical model using multiple regression to describe the influence of three machining parameters (current, pulse on time and pulse off time) on three objective parameters. 27 samples were run by using computer numerical control CNC based EDM machine which used for cutting steel 304 with dielectric solution of gas oil by supplied DC current values (10, 20, and 30A). Voltage of (140V) uses to cut 1.7mm thickness of the steel and use the copper electrode. Three predicted models have been developed using multiple regression method show a reliable accuracy to be used in this kind of cutting process. The result from this work is useful to be implemented in industry to reduce time and cost in MRR, Ra & HV prediction.

The Material Damping as Rayleigh Damping in the Vibrations of Square and Rectangular Metallic Plates

Najeeb U. Khan Mechanical Engineering Department, FETS Higher Colleges of Technology Dubai, United Arab Emirates [email protected] P. Bangaru Babu Mechanical Engineering Department National Institute of Technology Warangal-506 004, India [email protected] In this paper, an experimental investigation is carried out on square and rectangular plates of different materials with various edge conditions to estimate the Rayleigh damping coefficients. The determination of Rayleigh damping coefficients has become an important aspect of the dynamical analysis of delicate mechanical structural elements such as robotic arm manipulators, panels in space crafts and numerically controlled precision machine tools. The coefficients thus obtained are reinvestigated for a two-parameter model. Damping ratios can be determined by using estimated coefficients to assemble the Rayleigh damping matrix [C]. This method has been found to be very effective in the computation of the transient response using modal superposition technique and provides a methodology to have predictive computations of dynamic responses.

Simulating the Optical Properties of Isolated and Dimer Nanoshells for Photothermal Therapy Frank Gunzer and Maryam Magdy Faculty of Information Engineering and Technology German University in Cairo Cairo, Egypt [email protected] Photothermal therapy, the process of converting light from a laser into heat strong enough to destroy cancer cells, has risen as a promising, safe and minimally invasive means for cancer therapy. The ongoing progress in nanotechnology and material fabrication has revealed a novel class of metal nanoparticles whose free electrons resonate with incident light, exhibiting enhanced local electric field properties, an effect known as surface plasmon resonance. Designing nanoparticles that can efficiently absorb light is of critical importance for photothermal therapy while their ability to scatter light is useful for imaging. The presence of a simple, accurate and flexible method to investigate the optical response of different nanoparticle designs would be a huge step towards such goal. This work presents the use of the finite elements method to calculate the spectra of absorption and scattering efficiencies of gold nanoshells of different geometries. The size dependent dielectric function was used to model the gold shells. The results were compared to those of a previous study that uses Mie theory. The optical response of nanoshell dimers at different separations was also calculated and the results were compared with studies that use Wigner Eckart theorem, boundary elements method and experiments. Our model results were consistently found to be in very good agreement with those of the other studies. The finite elements method has proven its reliability to model the optical responses of nanoparticles and can be used to investigate more advanced nanoparticle designs that would be too complicated to model analytically.

Simulating the Optical Properties of Graphene Nanodisks for Photothermal Therapy Frank Gunzer and Maryam Magdy Faculty of Information Engineering and Technology German University in Cairo Cairo, Egypt [email protected]

Photothermal therapy, the process of converting light from a laser into heat strong enough to destroy cancer cells, has risen as a promising, safe and minimally invasive means for the treatment of cancer. Designing nanoparticles that can efficiently absorb light and convert it to heat is of critical importance for photothermal therapy. In the recent years, graphene has emerged as a tunable, versatile and promising material in a wide range of applications. There is a lack of studies on graphene based nanoparticles for photothermal therapy. This work presents the use of the finite elements method to calculate the absorption efficiency spectra of single and multiple layer graphene nanodisks of different sizes for the first time. For a graphene sheet, the electromagnetic properties were described in terms of the surface conductivity by Kubo model of conductivity. The results show that increasing the number of graphene layers or radii of nanodisks, increases the absorption efficiency. It was also noticed that the shapes of the absorption spectra of the graphene nanodisks do not have resonance peaks like those of the gold nanoparticles and instead have a more constant response. Despite the fact that the graphene nanodisks demonstrated possess much weaker absorption in comparison to gold nanoparticles, it is expected that increasing the number of layers further would increase the absorption efficiency till it becomes comparable to or maybe even better than gold nanoparticles. The results show the feasibility of graphene based nanoparticles for photothermal therapy and encourage more research on the topic.

Automated Sports Rim Design In CAD System M.S. Abdul Karim Department of Mechanical Engineering Higher Colleges of Technology (ADMC) Abu Dhabi, UAE [email protected] Ahmad Zulhakim Ab Rashid Department of Mechanical Engineering Nottingham University (Malaysian Campus) Selangor, Malaysia This research project is conducted to find ways to create automation at design stage in the light of reducing time to design within a Computer Aided Design (CAD) package. As current trend of product development is toward mass customizations, it is found that one of the most effective ways to implement automation in design is by automating the part-repetitive steps that need to be done every time the part is created. This project focused on developing a way to automate the repetitive steps and a case study on a wheel rim design is undertaken. From literature researches, it is found that in wheel designing process, the designer repeat the steps of creating the CAD data for the rim of the wheel which has standard sizing of its important profiles. The two driving dimensions in creating a wheel are the diameter of the wheel and the width which both have standard sizes. Using the function relation and family table in the CAD system, a relation driven table is created which stores the database of all the standard rim sizes available. The only manual thing that designer need to do in designing wheel after the automation is implemented is to design the spokes of the wheel. Again, using relation and pattern function, the number of the spokes can easily be changed as the designer desired. In the end, a method of creating a wheel in significantly faster way than the traditional method is produced. This study paves the way for an automated of repetitive elements in a particular design of intermediate to extremely complex and detailed design.

The present work is an exploration of a.c conductivity response and humidity sensing properties of IPANI/Ag/ BaFe12O19 (PAB) composites prepared by in-situ chemical oxidative method via interfacial polymerization using (NH4)2S2O8 as an oxidant at 0-30C. A series of composites with different BaFe12O19 wt% loadings (10, 20, 30, 40 and 50 wt%) was prepared. The prepared polymer composites were characterized by FT-IR, XRD and SEM techniques. FT-IR bands in the range 375-600 cm-1confirms the formation of hexagonal ferrite composite. SEM analysis clearly presented the structure of barium ferrite is hexagonal close-packed structure. The ac conductivity is found to be constant up to logarithamic frequency 4Hz and thereafter it increases steeply. The ac conductivity of 0.785Scm−1 at room temperature is observed as the maxima for the PAB- 50wt% composite. The synthesized composites are found to be sensitive to low humidity ranging from 10% to 97 % RH, indicating promising potential applications in gas drying, safe operation of insulating gases in switchgear in power industry, production of transformer and lithium batteries.

A Computational and Experimental Investigation of Airflow and Heat Transfer through Improved Horticultural Produce-Crates Abed Mennad Mechanical Engineering Department, FETS Higher Colleges of Technology Sharjah, United Arab Emirates [email protected] Najeeb U. Khan Mechanical Engineering Department, FETS Higher Colleges of Technology Dubai, United Arab Emirates [email protected]

In this paper computational and experimental work is presented on the forced-air precooling process. The process is a popular method normally used to minimize the post-harvest losses and to extend the shelf-life of a wide range of horticultural produce. In the method, cold air is forced by a fan to pass through vents and then around produce packed in a crate. During the cooling process, produce exposed to high air velocities are overcooled while others exposed to low air velocities are undercooled. This non-uniformity of airflow is a major problem and it is directly related to improper vents geometries in the crates. Therefore the correct venting is necessary to achieve rapid and uniform cooling of produce. However, package strength also needs to be taken into consideration. The influence of vent shapes on the cooling uniformity can be assessed by numerical and experimental means. This study therefore provides a viable means through numerical and experimental investigation to find the effect of variation in the size and location of vents in the crate including the effects of variation of inlet velocity on the airflow and heat transfer distribution within a crate filled with spherically shaped produce such as a plum. This work is, finally, an attempt to enhance the precooling process for spherically shaped produce.

Alkyl Chain Modified Diatomaceous Earth Superhydrophobic Coatings Helanka J Perera Math & Natural Sciences, Mechanical Engineering Division Higher Colleges of Technology, Abu Dhabi Women College, Abu Dhabi, UAE, UAE Frank D. Blum Chemistry Department Oklahoma State University, Stillwater Oklahoma, 74078, United States [email protected] Superhydrophobic surfaces were prepared with treated diatomaceous earth (DE) particles treated with different chain lengths at 2.2 mg/m2 silane treatment alkyltrimethoxysilanes (H3C(CH2)n-1-Si(OCH3)3 with n = 3, 8, 12, 16, and 18). The properties of the untreated and treated DE and untreated particles were characterized with thermogravimetric analysis (TGA), and temperature modulated differential scanning calorimetry (TMDSC). The wettability and surface morphology of treated DE polyurethane coatings were studied using contact angle measurements and scanning electron microscopy (SEM). Surfaces with C12 and greater alkylsilane length could become superhydrophobic. Alkyl chain lengths shorter than C12 only formed hydrophobic coating at 50% treated DE particle loading with polyurethane. SEM images showed an enhancement in surface roughness with increasing the chain length of treated DE.

In this study, molecular dynamics (MD) simulation has been used to assess this issue. Materials Studio 7.0 has been used as a tool for finding the modulus and thermal conductivity of nanocomposites. Two different computational models, SLGS/nickel and CNT/nickel composites have been examined to study the effect of nanofiller geometry on Young's modulus and thermal conductivity of these nanocomposites. The effect of nanofiller volume fraction (Vf) on Young's modulus and thermal conductivity has also been studied. Results show that with increase in Vf the Young's modulus as well as thermal conductivity of SLGS/Ni composites increases at a faster rate than for CNT/Ni composite. For same Vf , Young's modulus of SLGS/Ni composite is higher than CNT/Ni composite, showing that SLGS is a better reinforcement than CNT for Ni based composites.

Ravella* Associate Professor, School of Mechanical Engineering Lovely Professional University Phagwara-144411, India [email protected], [email protected] Prince Setia Research Scholar, Department of Material Science & Engineering, Indian Institute of Technology, Kanpur, India [email protected] Because of their high corrosion resistance, Ti and its alloys are widely used for chemical and petrochemical applications. Carbon nanotube reinforced Ti composites can be used in space and defense applications because these composites are lightweight and at the same time exhibit exceptional mechanical properties. In this study, the mechanical properties of carbon nanotube-Ti composites have been predicted using molecular dynamics approach. The effect of variation in carbon nanotube volume fraction, temperature and strain on the elastic and the shear modulus of carbon nanotube-Ti composites, was studied. The elastic and shear moduli were all found to increase significantly because of the increasing carbon nanotube volume fraction. Even at temperatures approaching 1 °K, the carbon nanotube-Ti composites show high values of elastic and shear moduli. The elastic moduli tend to attain a constant value at high levels of strain.

Using bore-epoxy anchorage to delay debonding of CFRP plates strengthened concrete beams Khalid M. Mohamed Department of Civil Engineering American University of Sharjah Sharjah, United Arab Emirates [email protected] Jamal A. Abdalla and Rami A. Hawileh and Waleed Nawaz Department of Civil Engineering American University of Sharjah Sharjah, United Arab Emirates [email protected]; [email protected]; [email protected]; Repairing of deteriorating structures has been done using different methods and techniques. Shear strengthening of Reinforced Concrete (RC) elements with externally bonded carbon fiber reinforced polymer (CFRP) plates and sheets have been widely used and accepted. It has been observed that debonding of the CFRP laminate and other strengthening materials is the most common type of failure. To address this issue many anchorage systems and methods have been developed. In this paper the use of bore-epoxy anchorage (Boring) system has been investigated. A total of five shear deficient RC beams were strengthened with carbon (CFRP) plates using bore-epoxy anchorage with bores of different diameters. The specimens were tested under four points bending. The results showed that the bore-epoxy anchorage delayed the CFRP de-bonding considerably and increased the shear capacity of the tested specimens by up to 48 % compared to the control beam.

Reinforced Concrete Beams Externally Strengthened In Flexure Using Hybrid Systems Abubakr Mohammed Department of Civil Engineering American University of Sharjah Sharjah, United Arab Emirates [email protected] Jamal A. Abdalla ,Rami A. Hawileh and Waleed Nawaz Department of Civil Engineering American University of Sharjah Sharjah, United Arab Emirates [email protected]; [email protected] ; [email protected] ; This paper presents the experimental results of nine full scale RC beams externally strengthened in flexure with different combinations of Aluminum, CFRP and galvanized steel mesh (GSM) hybrid laminates. Three groups of three beams were built with different flexural reinforcement ratios, and two beams in each group were strengthened with hybrid laminates in addition to control specimen. Coupon tests were conducted also to obtain the mechanical properties of the composite laminates. All the beams were tested under four-point bending and the load-deflection response had been recorded until the failure of the specimens. All the specimens failed in flexure and delamination was the controlling failure mode for all the strengthened specimens. Load carrying capacity of strengthened specimens increased from 27%-128% over the unstrengthened control specimen. It was also observed that the ductility and stiffness of the specimens increased due to the use of optimum hybrid laminates.

Finite Element Modeling of Thermal Deformations in Composite Materials Enrique Graciani, Alejandro Estefani, Federico París Grupo de Elasticidad y Resistencia de Materiales, Universidad de Sevilla, España [email protected], [email protected], [email protected] A comparative study of four different finite elements (FE) models to determine the thermal deformations in a typical aeronautical structure is presented. A detailed FE model with solid elements is used as a reference to determine the accuracy given by three FE model with shell elements. The component consists of three planar laminates with (relatively small) curved zones at the joints. The analysis shows that a correct modelling of the curved laminates is needed for obtaining accurate results. If the FE model with shell elements ignores the existence of the curved zones, as it is typically done in models used for stress calculations, unsatisfactory results are obtained. Precision is not significantly increased if the curved zones are modelled in detail and the properties of the shell elements in the curved zones are defined as it is done in the planar zones. For this reason, a technique for modifying the in-plane thermal properties of the elements modelling the curved laminates that forces them to follow the same shape changes observed in the real curved laminates is presented. The FE model with shell elements obtained with these curvature-modified coefficients of thermal expansion provides similar accuracy to that obtained with the FE model with solid elements, with a significantly lower computational cost.

Microstructures showed a significant grain refinement with increasing Zn content along with HA agglomerates on the surface. Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) showed that Zn addition in Mg-1Ca alloy is assisting in inhibiting cathodic corrosion while HA addition in Mg-(0-5)Zn-1Ca alloy is increasing anodic corrosion along with Zn. Further, cytotoxicity analysis using direct and indirect contact methods were performed using L-929 cells, which showed that Zn addition (0-3 wt%) slightly increases cell viability and non-toxicity in Mg-1Ca alloy whereas a considerable improvement is observed after HA addition in Mg-Zn-1Ca alloys. Mg-1Zn-1Ca/3HA and Mg-3Zn-1Ca/3HA alloys/composites were observed to have controlled corrosion and non-toxic to L-929 cells.

Characterization of 3D Preforms using In-Situ micro Computed Tomography Muhammad Ali A. Kamran Ahmed Khan Department of Aerospace Engineering Khalifa University of Science, Technology and Research 127788 Abu Dhabi, United Arab Emirates [email protected] Rehan Umer Centre for Future Materials, University of Southern Queensland, Toowoomba, 4350 Australia. [email protected] Compaction of composite reinforcement preform and resin infusion are two major steps in composite manufacturing by liquid composite molding processes. Understanding of the preform compaction and permeability characteristics is important for the process characterization and optimization. Existing methods either require a number of tedious experiments or numerical simulations using geometric models of the reinforcement preform. Geometric modeling approaches of the preforms fail to capture the real architecture as well as the effect of the compaction of the reinforcements. This study presents numerical computation of through thickness permeability of two types of 3D woven fabrics by in-situ compaction characterization using micro X-ray computed tomography (μXCT). The study involves extracting geometrical features of the fiber reinforcement, followed by detailed flow analysis using two different commercial software packages. The real-time 3D images obtained by in-situ compaction at four different fiber volume fractions. A bimodal segmentation was applied to separate the fiber tows from intra tow gaps. The gap analysis reveals significant changes in the meso-structure of the preform under applied compression. The conservation of mass and momentum equations were solved to obtain the flow field within the intra tow gaps for a representative volume element and Darcy's law was to obtain the preform permeability. The flow field analysis revealed three dimensional flow paths within the preform. The through thickness permeability values were in excellent agreement with the experimental data.

Enhancing Heat Transfer of Rectangular Fins - Implementing Constructal Optimization Approach Fadi Alnaimat, Mohammed Ziauddin, Bobby Mathew Mechanical Engineering Department, United Arab Emirates University, Al Ain, United Arab Emirates [email protected] Fin shape optimization is essential to enhance heat transfer by maximizing the heat flux and reducing material. This study examined rectangular fin shape optimized through material reduction and increasing effective surface area to enhance more heat flux. Simulation approach was adopted using ANSYS Workbench carrying out a Steady-State Thermal Analysis. The base temperature of the surface in contact to fins was assumed to be 100 °C. Basically, three cases of rectangular fins were studied: without modification, with circular cavities of 0.3 cm, and with circular cavities of 0.5 cm. The results show that, by introducing circular cavities, the heat flux distribution enhanced as well as there was reduction in the minimum temperature at the far edge of the fin.

Control of Airborne Noise Generated in the Cavities of a T-Slotted Aluminum Cylindrical Column Mohamad Y. Mustafa, Yizhong Xu, Bjørn Reidar Sørensen, Jose Santos Institute of Buildings, Energy and Material Technology UiT The Arctic University of Norway Narvik, Norway [email protected] Aziz Al-Mahadin Aviation Engineering Department, DBM Higher Colleges of Technology Dubai, UAE [email protected] This paper presents a study of airborne noise generated by a T-slotted cylindrical aluminum hollow column with six slots of the type used for the construction of communication towers. Noise is a very distracting phenomena and an environmental concern caused by various sources. Noise pollution is becoming more severe with the introduction of massive human activities and the use of heavy machineries, and hence, it has been investigated by many researchers to highlight its environmental impacts and to find methods for its attenuation. Worldwide research focus on noise measurement, comparison of the efficacy of different noise barriers, development of noise models, and proposing viable solutions for its attenuation. Many technologies have been utilized for noise mitigation including insulation, absorption, damping and isolation. In this research, to mitigate the airborne noise level, passive noise control methods are applied by changing boundary conditions and using different materials in the bottom of the cavities. The wind tunnel experiments and CFD modelling reveals that such passive noise control measures have significant effects on controlling the noise level. The investigation also includes CFD modeling for the impact of local velocity distribution in the cavity regions on the noise level.

Department of Mechanical Engineering, (HCT-ADMC). Shakhbout Bin Sultan Street, Abu Dhabi, UAE [email protected], [email protected],[email protected] The objective of this paper is to evaluate the influence of variation of processing parameters on the dispersion quality of polycarbonate compound. For proper dispersion of these pigments, the optimization of compounding process parameters is required. The effect of three processing parameters, temperature, screw speed, and feed rate, was investigated. Experimental design for the optimization of process parameter based upon 3 levels full factorial response surface methodology was utilized. Design expert software was employed to carry out the experimental designs, statistical and numerical optimization. Statistical equation developed by this method contained individual and interactions effects of parameters on the color values. The developed model and experimental data obtained passed all diagnostic tests establishing this model as statistically significant. The analysis of variance (ANOVA) reveals that the color parameters dL*, da* and db* are significantly influenced by the three parameters studied. The best possible optimum process parameters were found to be: 245.26 oC, 741.27 rpm and 24.72 kg/hr in order to achieve the color values in a minimum desirable deviation dE* of 0.8. Application was extended to study the variations of the processing parameters while other parameters are constant (General Trends), focused on the minute variation of the feedrates leads to a significant improvement in key color desirable deviation dE* of 0.34.

Their unique structural properties enable them to be designed to create complete Phononic band gaps, or ranges of frequencies in which elastic or mechanical waves are forbidden to propagate in any direction. This property particularly enables the researchers to develop models which can suppress or enable propagation of harmful or useful vibrations in select frequency ranges. The current research analyzes the application of the Phononic Crystal technology to develop surgical tools which can improve haptic force feedback enabling surgeons with better precision, and simultaneously attenuating hand tremor vibrations to adversely affect robotic surgery precision.

Faiz Bin Ramli**, Ari Legowo*, Syariful Syafiq Shamsudin** *Department of Mechanical Engineering, Kulliyyah of Engineering, International Islamic University Malaysia **Faculty of Mechanical and Manufacturing Engineering, Universiti Tun Hussein Onn Malaysia [email protected] Obstacle detection and avoidance is desirable for UAVs especially lightweight micro aerial vehicles and is challenging problem since it has payload constraints, therefore only limited sensor can be attached the vehicle. Usually the sensors incorporated in the system is either type vision based (monocular or stereo camera) or Laser based. However, each of the sensor has its own advantage and disadvantage, thus we built the obstacle detection and avoidance system based multi sensor (monocular sensor and LIDAR sensor) integration. On top of that, we also able to approximate the safe avoidance path for the UAV once obstacle is detected from far distance (7ft/211cm) without using fix tolerance dimension from the detected feature keypoints. In the initial experiment conducted, we successfully detect and determine safe avoidance path on 5 different sizes and textures of the obstacles including textureless obstacles.

Spray characteristics of plug type swirl injector Sri Nithya Mahottamananda Jayapal Department of Aerospace Engineering B.S.Abdur Rahman Crescent Institute of Science & Technology Chennai,India [email protected] Mohammed Rafnaz Department of Aerospace Engineering B.S.Abdur Rahman Crescent Institute of Science & Technology Chennai,India [email protected] Kadiresh P N Department of Aerospace Engineering B.S.Abdur Rahman Crescent Institute of Science & Technology Chennai,India [email protected] Atomization of liquids is a complicated process. It is a common phenomenon in many industries such as aerospace, automotive, manufacturing (spray drying) and mineral processing. In swirl injectors, swirling motion is spread to the fluid due to the effect of the centrifugal force to spread out in the form of a hollow cone liquid sheet as the fluid leaves the exit orifice. Swirl injector performance and flow behavior at exit will be best understood by the efficient design and dynamics of various types of injector. Combustion chamber efficiency is based on injector performance so minor deviations from its design can significantly affect the performance. The experimental investigation of plug type swirl injector at varying injection pressure is explored in this paper. The injection pressure was varied from 0.5 bar to 4.5 bar and water was used as working fluid. The measured parameters include breakup length of liquid sheet, spray cone angle, coefficient of discharge and volume flow rate. Experimental data shows that breakup length is decreased and spray cone angle is increased with increasing injection pressure. It is also observed that volume flow rate is increased with an increase in injection pressure and the discharge coefficient is decreased with low injection pressure but if injection pressure is increased it remains nearly constant. High spray cone angle and less break up length of plug type swirl injector is important spray characteristics requirement in hybrid rocket motor combustion chamber.

Development and Application of a Value Driven Design Assessment Framework to an Unmanned Air System Design Evangelos Papageorgiou, PhD Assistant Professor Aviation Engineering Technology and Science Higher Colleges of Technology Abu Dhabi Men’s College, UAE [email protected] The work presented concerns the development of a value driven engineering design assessment framework and its application to the conceptual design of an Unmanned Air System (UAS) to be utilised in a defence application. In the field of Multi-Disciplinary Design Optimization, most recent systematic search has been devoted to fixed topology parametric geometries, pertaining to a single concept, with very little stress put on the optimization of variable topologies describing alternative design concepts. Instead of pertaining to a single aircraft concept, a broad range of combinations of UAS configurations and geometries is generated by systematically searching alternative concepts and design configurations through a novel parameterization of the aircraft geometric topologies. Moreover, value, related to the designed system's capabilities or performance and lifecycle cost, is used to compare different alternatives in the decision making of engineering design through the appropriate value model. Following a value-focused approach, a novel multi-attribute value model is introduced for objectively capturing the user's preferences and expectations. Furthermore, a more sophisticated multi-attribute utility model, based on standard Multi-attribute Utility Theory, is employed in the evaluation. This research demonstrates the implementation of the value driven design philosophy in this framework, identifying value enhancing designs, with value not converted to monetary worth but as perceived by the user. The ultimate objective of this framework is to convert engineering design to a decision making analysis with multiple conflicting objectives considered.

The Applicability of The Adaptive Wavelet Analysis in Flutter Identification in Aerospace Structures Dr. Molham H. Chikhalsouk (1), Dr. Khalid Zhouri (2) Dr. Omar A. Khondker (3), Dr. Monsif Shinneeb(4), Dr. Mohamed Sharis Assistant Professor, Mechanical Department, ADM, Higher Colleges of Technology, UAE: (1)[email protected], The corresponding author (2) [email protected], (3) [email protected], (4) [email protected], (5) [email protected] Chikhalsouk (Higher Colleges of Technology) This paper examines the use of wavelet analysis in detecting flutter in aircraft structures such as airplane wings and control surfaces. Particularly in combat aircrafts, the designs are pushed to the limit to obtain the best performance from the aircraft. It is extremely important to detect the onset of flutter during any complicated maneuvers. The flutter is encountered when the fluid or air excites the structure by delivering energy to the structure instead of absorbing it, thus making the damping of the structure negative which results in excessively increasing vibrations. Use of wavelet analysis has shown good results in detecting the onset of instability in several ground-based structures, and the present study is an attempt to apply it in detecting flutter in aircraft wings. A continuous wavelet transform is used to analyze the vibration signatures from aircraft wings and representing it in both time and frequency representation. The mother wavelet is selected to be Debauches. Debauche's mother wavelet is recommended for applications with impulsive nature. The data are collected experimentally. The results show the applicability of wavelet analysis in identifying the flutter for this type of applications. The wavelet transform has shown a remarkable competency in identifying the flutter in the continuous aerospace structures. INTRODUCTION Flutter is an aeroelastic instability which can take place on any aerospace structures and pipes, which are continuous structures. It is a repeating movement with a destructive nature, where the continuous movement causes the fatigue of the structure and leading to its collapse. Flutter identification is a fundamental procedure in designing the structures, where the dynamic stability and the structure damping at the range of fluid/air flow speeds can be determined. Different techniques are used to analyze the flutter such as K, KE, PK, and methods. These techniques require substantial resources, such as those are found at NASA, to conduct these tests [1]. However, in the recent years, experts started investigating the applicability of Wavelet Transform, WT, in investigating different phenomena and they found that the WT is very convenient for most applications. In the present paper, a new technique is proposed to identify flutter by using the wavelet transform. The transform has two parameters, which are the scale and translation factors. WT transforms the signal in time-frequency fashion, and that happens to aid of a bank of band-pass filters, and every filter allows the certain band to pass [4]. Staszewski and Cooper [3] considered the flutter phenomena in aircrafts and identified damping during flight test. The flutter test data was evaluated by using a time-scale domain method. The flutter was produced by exciting the structure by impulsive force, and the corresponding response was recorded and analyzed.

A similar study was conducted by NASA [1]. The study used wavelet transform to reduce uncertainty levels in stability estimates and provided valuable data for analysis of excitation mechanism and stability boundary prediction. Chikhalsouk and Bhat, [4], studied the stability in pipes conveying fluids. Their study examined the conditions at which the pipe loses its dynamic (flutter) and static stability (divergence).

Investigation Of Factors Affecting Aircraft Vortex Encounters Aziz Al-Mahadin Aviation Engineering Department, DBM Higher Colleges of Technology Dubai, UAE [email protected] Serdar Dalkilic Aviation Engineering Department, ADMC Higher Colleges of Technology Abu Dhabi, UAE [email protected] Large Aircraft wake vortices may sometimes cause significant disturbance to following aircraft. Separation standards between leading and following aircraft are proven to be overestimated in some cases, and therefore reducing airport capacity. Other times they are underestimated and hence causing aircraft incidences and accidents. An important contribution to the formation and revision of vortex separations depends on the recognition of vortex traverse by analysis of pilot reports together with a manual examination of data from flight data recorders (FDRs). However, the current process of flight events analysis is sometimes subjective and time consuming. Furthermore, there is sometimes disagreement between pilot reporting and analysis of flight data from FDR. Hence the current process requires improvement. This paper examines 54 pilot reports of transport aircraft vortex encounters to establish factors affecting the encounters. The research findings help the aviation authorities to impose new requirements such as training for pilots and FDR analysts on vortex identification. Findings can also contribute to enhance safety, improve operation efficiency and helps revision of the appropriateness of regulations of vortex separations. This paper also indicates further investigation areas that are essential for aircraft wake vortex analysis, identification and severity mitigation.

Neuro-Fuzzy Techniques for the Identification of Aircraft Wake Vortex Encounters Aziz Al-Mahadin Aviation Engineering Department, DBM Higher Colleges of Technology Dubai, UAE [email protected] Faouzi Bouslama Computer Information Science Department, DBM Higher Colleges of Technology Dubai, UAE [email protected] The automatic identification of aircraft vortex encounters by soft-computing techniques, such as fuzzy systems, gives better identification results than when performed by subjective manual approaches. However, the construction of the fuzzy rules heavily depends on a thorough understanding of vortex aerodynamics and aircraft response to a vortex encounter. Moreover, it requires a detailed analysis of flight data records and pilot reports, which all help in the proper selection of the critical fuzzy input variables. However, the automatic identification of vortex encounters by fuzzy logic can be greatly influenced by the shape and distributions of membership functions. Artificial neural networks integrated with fuzzy systems have been used as a solution in the automatic tuning of the membership functions of fuzzy linguistic variables. In this paper, a hybrid Adaptive Neuro-Fuzzy Inference System (ANFIS) is selected to automatically tune the parameters of the fuzzy membership functions. Various neuro-fuzzy models having different sets of parameters and factors are investigated. Simulation results with an average identification accuracy of 84.2% is obtained. The neuro-fuzzy hybrid model can also be used in the identification of other aircraft flight events.

Banasthali University, India Balgopal Singh Associate Professor- Faculty of Management Studies Banasthali University, India Safety has always been a concern for aviation organizations; however, most of the research that has been done in this field is related to safety culture in flight operations and not directly related to the Aircraft Maintenance Organizations (AMO). However, the holistic flight safety depends on the conduct of individuals from both Aircraft Maintenance Organizations and flight operations. The risk factors from aircraft maintenance are very crucial and if not mitigated on time, can lead to more accidents and serious incidents. Safety regulations adapted by Safety Management Systems (SMS) may not be always followed because of alleged reasons including time constraints and cost reduction. This problem can be prevented by creating a safety culture. Hence embracing aviation safety culture is very important to guarantee the required safety outcomes. This research aims to provide an overview of the effective implementation of safety management systems and evaluate the safety culture in maintenance organizations in the UAE. The research outcomes and recommendations will help maintenance organizations to enhance the level of safety by adopting an effective safety culture and ensuring effective implementation of safety management system.

Colonization on Mars: An Experimental Analysis about Chromotherapy as key to survive on Mars Asma Helal Ali Alyahyaee (Student), Hind Mohamed Ali Alkhawajah (Student), Khalid Hussain (Lecturer) Petroleum Engineering Technology Abu Dhabi Polytechnic Abu Dhabi, UAE The red planet (Mars) has fascinated the human kind for a very long time. Even human beings have explored and conquered almost all the world, but curiosity has led them to expand their limits and explore the space. After the revolution in technology, the human species is on the verge of achieving a historic accomplishment to establish a permanent human settlement on Planet Mars. But traveling to a place which is 54.6 million kilometers away from us is a big challenge. The primary problem for the Mars-bound crew will be the very long flight, which will last about eight months. The long travel in a small spaceship will be a challenging psychological experience. Continues and sustainable source of food and energy is another critical challenge because Martians will not be able to grow green plants on Mars. The unavailability of the viable food source leads Martians to take their food for the whole journey from earth which results in more congestion of space. The conventional resources are not going to help us in such a complicated mission. Visible light, the aggregate of various colors, is an instant source of energy. The right used to light sources and its color could be a helpful tool in our journey to Mars. The series of experiments on humans show that color therapy can be a practical solution to food and alternative medicine deficiency. Our experimental analysis has proven that specific color light can help plants to grow and nourish. We have also done chromotherapy of Hamster under different color lights and conditions.

A Numerical Analysis of the Slot Film-Cooling Effectiveness Mohammed Al-Hemyari Mechancial Engineering Department American University of Sharjah Sharjah, UAE [email protected] Mohammad O. Hamdan Mechancial Engineering Department American University of Sharjah Sharjah, UAE [email protected] Mehmet F.Orhan Mechancial Engineering Department American University of Sharjah Sharjah, UAE [email protected] Cooling gas turbine blades is crucial cooling techniques that allows higher gas turbine inlet temperature. A higher gas turbine inlet temperature allows boosting gas turbine efficiency which reduces fuel consumption. One of the main cooling techniques of the turbine blades is film cooling where a relatively low temperature air is used to form a blanket of cool air around the blade to shield it from high temperature gases. Many complex interrelated geometry and flow parameters affect the effectiveness of the film cooling. The complex interrelations between these parameters are considered the main challenge in properly understanding the effect of these parameters on film cooling. Numerical techniques are viable analysis techniques that are used to better understand film cooling techniques. In this study, a simplified 2D film cooling jet blown from slot jet is investigated for blowing ratio for a wide range between 0.5 and 2. The performance of the film cooling is reported using adiabatic film effectiveness.

Sharjah Center for Astronomy and Space Sciences. Sharjah, U.A.E [email protected] [email protected] Global Positioning System (GPS) is a worldwide radio-navigation system through which the position of an object on Earth and in its vicinity can be precisely calculated. However, errors in the satellites signal propagation affect the positioning calculation done by ground receivers. The Ionosphere is the most significant source of that error, with errors scaling up to tens of meters. To eliminate Ionospheric errors, the number of total electron content (TEC) in the Ionosphere must be calculated. In this study, a comparison has been performed between the peaks of the seasonal graphs obtained by daily calculations of vertical total electron content of two collocated receivers (BAHR & BHR1 / BHR1 & BHR2) and the daily total sunspot number (DTSN). We found there to be a direct correlation between the two.

Heat Transfer Influence of Solar Panel on Spacecraft Reem Almehisni Mohammed Bin Rashid Space Centre (MBRSC) Dubai, UAE [email protected] Fadi Al Naimat Mechanical Engineering Department United Arab Emirates Al Ain, UAE [email protected]

Solar Panels are widely used in space applications; they serve as the primary electrical power source for the spacecraft mission. When the spacecraft orbits the earth planet in low earth orbit, the solar panels undergo harsh thermal environment of space where they experience the extreme high temperature exceeding 120˚C while in sun exposure and low temperature around -170˚C while in eclipse shadow. This paper studies the significant thermal effect of solar panel heat flux, with temperature range between -60˚C to 100 ˚C, imposed on the spacecraft's body structure through deriving thermal equation of the system and conducting thermal analysis simulation for different thermal paths between a solar panel and a spacecraft. The different thermal paths are compared and discussed in the paper to predict the most effective heat path such that it is capable of decreasing the mass and cost of thermal control systems of spacecraft.

Chithirai Pon Selvan Faculty Member Mechanical Engineering Department Amity University Dubai Dubai, United Arab Emirates [email protected] For decades composite materials have been used in aviation industry, but the forth coming generations of airframe structures will be the first in which the major fundamental component are fabricated from composites instead of metals. The fabrication of Three Dimensional spacer fabric is a recently established concept where the surfaces of fabric are strongly interlinked to each other by vertical pile fibers which are interwoven using different techniques with the skins. Hence as a result of this new technique, better skin-core debonding resistance, superior integrity and perfect durability is achieved. In addition, the interstitial space of the construction can be filled up with foams to provide synergistic support with vertical piles. This paper discusses on the fabrication of the composites and in the secondary stage understanding the mechanical properties of the specimen by flexural testing and in the final stage comparison of test results.

Estimation and Reduction of Helicopter Hub Vibratory Forces due to Blade-to-Blade Dissimilarity in Composite Rotor System Babruvahan Ronge Department of Mechanical Engineering SVERI’s College of Engineering Pandharpur, India [email protected] Prashant Pawar Department of Civil Engineering SVERI’s College of Engineering Pandharpur, India [email protected] In the conventional helicopters, the main rotor provides necessary lift capability to meet various mission requirements. However, the main rotor system is the principal source of distractive vibrations, which restricts helicopters from achieving higher speed, maneuverability, agility, and crew effectiveness. These vibrations can be divided into two categories. The first category of vibrations is inherent due to the asymmetric nature of a rotor in forward flight and are present even in the case of a balanced rotor (tracked rotor) system. The second category of vibrations is due to the blade-to-blade dissimilarity which results from manufacturing uncertainties, highly vibratory operating conditions and environmental effects. High levels of vibration and noise are key issues of concern for helicopter industries. Further, the extent severity of these vibrations increases due adding of few more harmonics vibrations coming from blade-to-blade dissimilarity. This dissimilarity may be result of various uncertainties, blade degradation due to highly vibratory operating conditions and environmental effects. Therefore, it is important to estimate the extent of extra vibratory loads coming from this dissimilarity. Most of the efforts until now are focused on minimization of hub vibratory loads by assuming the balanced rotor system whereas the dissimilarity is minimized separately using "track and balance" system. This study is focused on the estimation of hub vibratory loads due to dissimilarity and its elimination using active twist control.

Experimental Analysis of Composite Rotor blade models for damge identification Babruvahan Ronge Department of Mechanical Engineering SVERI’s College of Engineering Pandharpur, India [email protected] Prashant Pawar Department of Civil Engineering SVERI’s College of Engineering Pandharpur, India [email protected] Avinash Parkhe Department of Mechanical Engineering SVERI’s College of Engineering Pandharpur, India [email protected] The helicopter rotor system operates in a highly dynamic and unsteady environment leading to severe vibratory loads. Repeated exposure to this severe loading condition can induce damage in the composite rotor blades. These blades are generally made of fiber reinforced laminated composites and exhibit various competing modes of damage such as delamination, fiber matrix debonding, fiber breakage, fiber pull out and matrix cracking. There is a need to study the behavior of the composite helicopter rotor system under various key damage modes in composite materials, as this understanding can then be further used for developing a Structural Health Monitoring (SHM) system which will be able to predict these key damage modes in the helicopter from the measured data. An experimental study for understanding the combined influence of damages is carried out. Experimental analysis is carried out for non-rotating and rotating conditions. In the non-rotating conditions fundamental properties of composite rotor blade model viz. stiffnesses and natural frequencies in various directions are obtained. For the rotating conditions strains in various directions are measured for damaged and undamaged rotor blade models. Further, dynamic responses of undamaged and damaged blade are also obtained for rotating as well as non-rotating conditions.

Banasthali University, India

The rising number of aircraft in the country and the new civil aviation policy only forecast an enormous requirement for regional aircraft in the country in the future but this has also raised the concern regarding the availability of a required number of skilled and qualified workforce. The skilled manpower is the backbone of the aviation industry for the safe operation of airlines but the way it is expanding in India, it would be difficult to have a sufficient number of skilled manpower to meet the requirement of growing aviation industry. This demand for a skilled workforce is very high and cannot be addressed by existing training infrastructure. The situation will get worse if the effective and immediate actions are not taken on time. To effectively overcome this problem, the government has to come forward with an agenda addressing the key elements such as training needs, training infrastructure, and workforce planning. There is strong need of simplified policy along with strong determination from the government as well as private sector to support this growing sector in term of investment in training, better wages, healthier lifestyle and adoption of latest technology.

Study and testing of a green trainer to transform small general aviation aircraft for training into no-emission aerial vehicles 1st R. Alberto Bernabeo Abu Dhabi University, Abu Dhabi, UAE [email protected] 2nd L. Piancastelli University of Bologna D.I.N, Bologna, Italy [email protected] 3rd Zahid Hameed Malik Abu Dhabi University, Abu Dhabi, UAE [email protected] 4th Asif Al Azad; Abu Dhabi University, Abu Dhabi, UAE [email protected] 5th , Jamal Ahmed Yaseen Abu Dhabi University, Abu Dhabi, UAE [email protected] Most current trainers are piston engine aircraft. The engine lasts 2,000hrs. maximum. The idea is to substitute the engine with a green electric powerpack with the same performance of the original unit, but with no emission and basically with no maintenance. The powerpack should be easy to install, safe and should provide sufficient autonomy. This last part is particularly easy for trainers, since they fly in a very standard way. At morning, with the battery fully charged, the instructor and the student perform a flight that lasts typically from 20min to 2 hours. On landing a de-briefing of the student takes place. This phase is followed by the briefing of the new student. These two steps take at minimum of 30 minutes. During this time the battery can be partially recharged. The process will continue for a full day, with a longer recharge during break times. Therefore, it is perfectly possible to have a one day autonomy (about 10hrs.). This project is intended to develop an experimental green trainer to validate the best configuration for this power pack and to find-out critical issues on installation, safety, reliability and maintenance. Finally, a minimum number of 300hrs. of flight will be performed to perform an accelerated tests to individuate critical safety issues on

Scale Invariant Feature Transform (SIFT) is used for local features description of images. The proposed technique employs SIFT in order to match binary images. While the employment of SIFT descriptors on binary image databases could be possible, its power is rather limited. The novelty of the proposed algorithm is make use of SIFT for binary image matching by taking the power of Hough Transform (HT) in line detection. HT can be used on any line orientation. Thus, HT investigates lines as criteria for binary image similarity beside SIFT features for local and corner descriptions. The evaluation is achieved and experimental highlights the superiority of this approach for binary images which contains straight lines.

Platform Dependent Delay and Pitch Shifting Using Android Environment Ammar Natsheh, Higher Colleges Technology, United Arab Emirates [email protected] This Paper is about finding a low cost solution to Audio effects used by musicians and audio engineers. From chorus to flanger, rotary, delay, overdrive, and pitch shifting, etc… This paper focuses on two effects: Delay and Pitch shifting. The first part the delay was used since the beginning of using electronics in musical instruments. It adds some delayed versions of the input signal which gives a warm tone and adds a depth to the sound of the instrument, from a psychological point of view it keeps hitting the ear drum of the listener to a level where the ear is used to it and actually is some strange type of a very short time addiction. It was done through using a circular buffer technique to save the memory and to get rid of latency. The second part is the pitch shifting. It actually allows one person to play two lines at the same time, giving the listener a variation of frequencies that hit the low pass filter which is the human ear, making some sort of linear surrounding effect depending on how the panning of the original signal and the shifted version is done. The techniques used are carefully selected and implemented with some types of interpolation to make sure to get the best results. Notes:

Al-Aubaidy Electrical Engineering Department, Higher Colleges of Technology, UAE [email protected] Saloa M. Ali Electrical Engineering Department, Higher Colleges of Technology, UAE [email protected] In this paper, we present a new technique of reducing PAPR for OFDM transmission to meet the increasing demand of an efficient OFDM realization for IOT networks. PAPR reduction is based on code multiplication with several circular shifts of the input mapped vector and the selected vector is the one with minimum PAPR. Compared to the selected mapping (SLM), only one code is required, iteration process is done via circular shift of input vector, and side information is implicit in the data vector. Pilot SCs with carefully selected indexes are inserted to the data vectors for implicit determination of circular shifts and channel estimation at the receiver. We also present a low-complexity implementation algorithm for OFDM baseband transmitters, in which no complex multiplication is required at all. PAPR of 5.5-6.5dB per 10000 OFDM symbols is achieved for 16-QAM and 64-QAM with limited loss of power and bandwidth. Besides, no error in the extraction of the side information is detected at the receiver assuming frequency selective fading channel with 5, 70, 140 Hz Doppler shifts and up to 5 MHz OFDM bandwidth.

Revisiting of elliptical curve cryptography for securing IoT Darshana Pritam Shah Student ,Department of E& C Engineering R V College of Engineering Bangalore , India [email protected] The Internet-of-Things (IoT) is a network of 'Things' connected to internet where things can be a coffee machine, cell phone, headphones, lamps, wearable devices and almost anything else you can think of. These devices will communicate with cloud for sharing information via internet. Due to cheap availability of broadband internet, by 2020 almost 20 billion devices will be connected IoT. As these devices are connected to internet, security is the major concern. IoT devices will be vulnerable to all kind of active and passive attacks. In continuation, this paper proposes a secured protocol based on elliptic curve for communication between IoT devices and server. In the proposed Elliptical Curve Internet of Things (ECIOT) protocol, the IoT device will establish secret session key with server by using Diffie Hellman protocol based on NIST p-192 prime curve. The subsequent communication will be carried out with symmetric key cipher Ex-OR by using ECIOT derived key. The NIST p163 bit elliptic curve is recommended due to resource constrained nature of IoT devices. Implementation of the proposed ECIOT protocol is demonstrated on MIRACL crypto library. Keywords—Elliptical Curve Cryptography, discrete Logarithmic problem, Internet of Things, public key cryptography etc. Notes:

Commercial 4G LTE Cellular Networks for Supporting Emerging IoT Applications Ahmed Hassebo, Muath Obaidat, and M. A. Ali Dept. of Electrical Engineering, the City College of the City University of New York, NY 10031, USA [email protected] [email protected] [email protected] This paper presents a detailed realistic performance analysis and feasibility assessment of commercial LTE cellular networks when used to support a diverse set of emerging IoT applications ranging from mission-critical applications that require ultra-reliable and stringent E2E latency to those that require support of massive number of connected devices with relaxed latency and reliability requirements (e. g., smart meters). Since total uplink (UL) traffic of most of these IoT applications is higher than total downlink (DL) traffic, we focus our analysis only on UL performance. It is shown that current commercial 4G LTE systems can't support emerging mission-critical IoT applications with latency requirements of less than 100 ms. 4G LTE systems can satisfy the requirements of IoT applications when latency requirements are > 150 ms.

Proactive Noise Mitigation In Swash Plate Pump Pumping Systems: From Control System Design Perspective Molham H. Chikhalsouk (1), Khalid Zhouri (2) Chandra Somayaji (3), Monsif Shinneeb(4) Mechanical Department, ADM, Higher Colleges of Technology, UAE: (1)[email protected], The corresponding author (2) [email protected] (3) [email protected] (4) [email protected] Generally, in hydraulic systems, the performance, high specific power, and compliant functional characteristics make swash plate pumps suitable for most of the fluid power and hydraulic applications. Swashplate pump is a variable displacement pump as the flow rate is controlled and adjusted according to the load pressure reading. The pressure transducer senses the value of the pressure at the load side and sending it to the logic unit to determine the what is the required piston stroke needed to generate the required pressure to match the load pressure. For this purpose, the control unit is equipped with two control loops. The inner controls the spool proportional motion, and the outer to control the swash plate inclination angle which determines the stroke length. The inclination angle is limited by two values zero and 15 deg. Having one loop to control only the inclination angle makes the pump production cost less, simplify the structure of the pump, and improves the pump overall performance. Hence, the control unit needs to be redesigned and reconstructed to meet the required performance. This paper aims to investigate the effect of a single PID controller gains on the hydraulic system noise levels. In this study, the single proposed PID controlled will be compared with another single PD controller, and the noise levels will be considered as comparison parameters. The results are obtained theoretically and validated experimentally. The experimental results have shown the ability to apply the proposed PID single controller for this kind of pumps.

Entropy Based Adaptive Image Compression Procedure Sandor Piros (HCT Dubai Men's College, United Arab Emirates); Peter Korondi (BUTE, Hungary) There are several different methods to compress digital signals, datasets or images, each of them with special characteristics. The procedure introduced here is an entropy based adaptive compression method, its main feature is the hierarchical structure and entropy based compression. Wavelet transform of a dataset could be arranged to a binary tree like structure, which is the starting point of the proposed compression method. Degree of complexity of an image varies, different parts have different information content. Detailed regions require more thorough description than relaxed, predictable parts. To accomplish this task a new type of variable is introduced, resembling the entropy of a particular area of an image. The higher the value of this variable indicating entropy, the higher is the importance of the area's detail coefficients.

Real-time three Dimensional Imaging of Paramagnetic Contaminants in Oil-Gas Pipelines K. Bin Said1 and M. Meribout2 1: Electrical Engineering Department, University of Science & Technology (USTHB), Algiers, Algeria 2:Electrical Engineering Department, Petroleum Institute, Abu Dhabi, UA) In this paper, submillimeter three dimensional tomography imaging of paramagnetic contaminants flow rate in multiphase flow pipelines is presented. The device, which is based on Magnetic Particle Imaging (MPI), consists of an array of twelve coils and a pair of permanent magnets and is not influenced with the other phases that constitute the crude oil (e.g. oil, water, sand, and gas) and which are mainly diamagnetic materials. The concentration of the paramagnetic particles can be measured in a three dimensional volumetric space with high spatial and temporal sensitivities which are proportional to the strength of the applied magnetic field. This is also influenced by the size and distribution of the particles and the anisotropy of the permanent magnet. To increase the sensitivity and improve the spatio- encoding field, a two dimensional Linear Field Scanning (LFS) technique coupled with a two dimensional excitation field is proposed. The results demonstrate that the technique would constitute a breakthrough in the area of solid flow measurements and imaging. Notes:

The impact of topology on Internet of Things A Multidisciplinary Review Giulia De Masi School of Engineering Canadian University in Dubai Dubai, UAE [email protected] The Internet of Things is an emerging new field in the scenario of modern telecommunications. It is expected that by 2020 it will consists of billions of things or objects connected through Bluetooth and wireless connections. This is a huge network consisting of nodes -as sensors, actuators, RFID tags, mobile phones etc.- interacting each other and cooperating to reach common goals. IoT is characterized by a large heterogeneity both of objects and connections. Despite this heterogeneity, different objects interact through their complex architecture of connections (topology). Topology plays a crucial role in main issues of IoT, like traffic, delay, scalability, power consumption, synchronization, error tolerance, automatic search of devices and malware diffusion. The theoretical background to study IoT spans different disciplines, from Engineering to Mathematics (Graph Theory), from Statistical Physics (in particular Complex Networks) to Social Sciences. This paper tries to review the existing literature from different scientific communities and provides main concepts from Graph Theory and Complex Networks to analyze the IoT topology and model its dynamics and evolution.

Magnetorheological Elastomer Mounts in Non-linear Vehicle Model Ismail Ladipo Dept. of Mechanical and Mechatronics Engineering, Higher Colleges of Technology, Sharjah, UAE. [email protected]

The use of smart materials in engineering applications is a growing field of research. Various smart materials have been studied and used. One of such materials with evolving applications is the Magnetorheological Elastomer (MRE). As more applications areas of smart materials is being researched, simulation results which can be used to understand and predict the behaviors of smart materials are necessary. In this study, a developed mathematical model for MREs is used as an engine mount and experimentally simulated in the non-linear half-car vehicle model. The MRE mount model dynamic stiffness and damping modulus is then tuned to attenuate engine displacement vibrations in the low bandwidth frequency range (0-15Hz). Comparing the passive mount with MRE mount, the results show that, while there is considerable vibration reduction, the MREs mounts in practicality needs to be adaptive to excitation frequency (engine speed) to produce desired reduction in engine displacement.

A Novel Image Encoding and Communication Technique of B/W Images for IOT, Robotics and Drones using (15, 11) Reed Solomon Scheme Muhammad Zaid Ejaz (1), Dr. Khurram Khurshid (2), Zeeshan Abbas (3), Department of Electrical Engineering Institute of Space Technology Islamabad, Pakistan [email protected] [email protected] [email protected] Muhammad Ali Aizaz (4), Department of Electrical Engineering University of South Asia Lahore, Pakistan [email protected] Dr. Asif Nawaz (5) Faculty of Engineering Technology and Sciences Higher College of Technology Dubai, United Arab Emir

In the modern age of IOT and Robotics, different intelligent entities like robots, drones, IOT nodes or smart vehicles need fast and error-free communication of data, which is predominantly in the form of images. The medium used for communication of this data is mainly wireless and it can be short distance, medium distance, long haul or even satellite links crossing the ionosphere layers. Different wireless mediums incorporate different types of noises in the images being transmitted by Drones, Robots or IOT Nodes. For better analysis and then performing subsequent action on the basis of these received images using artificial intelligence, machine learning or machine vision, it is imperative that the images transmitted are encoded and recovered as fast and as error-free as possible. Normal conventional methods use different image correction algorithms for detection and correction of errors in images. Reed Solomon codes, which are normally used for error detection and correction at data link layer in TCP/IP protocol stack, have a high probability of signal correction and are highly efficient due to their burst error detection and correction capabilities. The RS codes can be implemented where there is a large number of input symbols and noise duration is relatively small as compared to the code word. Sometimes at the receiver end, we get images which are partially corrupted and only half or some part of them is visible. Most of the filters used for image reconstruction insert the approximated bits in place of the corrupted bits by using some algorithms but if only partial part of the image is corrupted no filter will be able to recover the images properly as it will also change the bits in the non-corrupted part of the image. We have proposed a novel approach of using RS codes for the detection and correction of errors in the images. This novel technique can be used over a variety of applications

There are numerous challenges to be addressed like limited availability of the radio frequency spectrum, an increase in requirement of better quality transmission, transmission problems such as multi path fading, inter channel interference etc. This study is to investigate how information fusion of same signals from multiple receivers improves on the accuracy of reception when compared to reception by a single receiver. We will focus on the use of hybrid sensor and information fusion to improve signal reception for a Multi Receiving digital communication System using Bi-linear Time-Frequency Analysis for parameter extraction, in a multi-path fading environment. Performance of classifiers is evaluated by comparing their performance at different SNRs. The classification accuracy of receivers will be different as each receiver has different propagation characteristics. Different types and levels of information fusion are compared and the most suitable method for this application is selected. This method aims at combining the signal at sensor level and decision level thus making it a novel hybrid method of multi sensor information fusion.

High availability is always expected for the continuation of operations in a plant. However, this objective is unable to attain due to unplanned breakdowns. This paper works on improving the availability of system by accurately handling the fault information. This was made possible by proposing a subsystem-based robust control. The overlapping decomposition was employed to tackle the variations independently for each state. The stability of the system was proved further using Lyapunov stability criteria. Performance evaluation was then conducted on an interconnected continuous time stirred tank reactor (CSTR) with recycle. The proposed scheme effectively controlled the faults to avoid costly failures.

Pitch Control of Wind Turbine through PID, Fuzzy and an Adaptive Fuzzy-PID Controller Silpa Baburajan1, Dr. Abdulla Ismail2 1Graduate Student, Dept. of Electrical Engineering, Rochester Institute of Technology, Dubai, UAE 2Professor, Dept. of Electrical Engineering, Rochester Institute of Technology, Dubai, UAE Recently, the renewable energy, especially wind energy, has been paid much attention due to the energy shortage and environmental concern. As the penetration of the wind energy into the electrical power grid is extensively increased, the influence of the wind turbine systems on the frequency and voltage stability becomes more and more significant [1]- [4]. Wind turbine rotor bears different types of loads; aerodynamic loads, gravitational loads and centrifugal loads. These loads cause fatigue and vibration in blades, which cause degradation to the rotor blades. These loads can be overcome and the amount of collected power can be controlled using a good pitch controller (PC) which will tune the attack angle of a wind turbine rotor blade into or out of the wind. Each blade is exposed to different loads due to the variation of the wind speed across the rotor blades. For this reason, individual electric drives can be used in future to control the pitch of the blades in a process called Individual Pitch Control. In this thesis work, a new pitch angle control strategy based on the fuzzy logic control is proposed to cope with the nonlinear characteristics of wind turbine as well as to reduce the loads on the blades. A mathematical model of wind turbine (pitch control system) is developed and is tested with three controllers -PID, Fuzzy and an Adaptive Fuzzy-PID. After comparing the three proposed strategies, the simulation results show that the Adaptive Fuzzy-PID controller has the optimum response as it controls the pitch system as well as the disturbances and uncertain factors associated with the system.

The Role of Electrical Heat Pump in Multi Energy Systems Iman Gerami Moghaddam Department of Electrical Engineering Persian Gulf International Branch, Islamic Azad University Khorramshahr, Iran [email protected] Leyla Bashiri Khouzestani Department of Electrical Engineering Islamic Azad University, Arak Branch Arak, Iran [email protected] Currently, the use of heat pumps is expanding. The use of these equipment in energy systems, due to their high efficiency is very useful. In this paper, the effect of using Electrical Heat Pump (EHP) in scheduling an energy hub for supply of cooling, heating and electrical loads of a building is investigated. Also, the effect of cooperation of EHP and co-generation system in improvement of energy performance of the energy hub is evaluated. The goal of presented MINLP model which plans the energy hub for the next 24 hours is minimization of operation costs. In order to scrutinize the role of EHP and the performance of presented model, six cases are considered for the energy hub in two sample summer and winter days in which, the energy hub supplies cooling and heating loads via electricity only, fuel only and their combination. The results show that the presence of EHP whether in cooling section or heating section, plays an important role in decreasing costs and fuel consumption. Furthermore, a precise investigation of operation work points of co-generation system and variations of the CHP operation scheme with the presence of EHP in the energy hub is accomplished.

Experimental Evaluation of a Wind Turbine's Energy Dependence on Air Density Dr. Yacouba Moumouni Higher Colleges of Technology, Ras al Khaimah, UAE [email protected] Dr. Nicolae Galupa Higher Colleges of Technology, Ras al Khaimah, UAE [email protected]

Fundamentally, all the major sources of renewable energy, such as solar, biomass, hydropower, and wind depend on the sun's radiation. An experimental evaluation of a changing air density impact on a small wind turbine's output power was investigated. The focus was first on deriving the theoretical wind power, followed by the actual extractable power in line with "Betz law." Second, the laboratory-based experiment utilizing the "leXsolar" wind equipment was set up according to the manual. Results showed that by using some "base values," including an air density of 1.195 kg/m3 at standard atmospheric pressure, a wind speed calibrated at 4.85 m/s, and an ambient temperature of 22ºC, the output voltage and current were 1.74 V and 45.2 mA, respectively. A Spreadsheet software was then utilized to fill in the missing values starting from zero to "base values," and beyond. Finally, counter-intuitive results were observed as both theoretical and actual powers yielded a positive slope while the air density decreased with increasing temperature. Notes:

Sizing an Off-grid Photovoltaic System Dr. Yacouba Moumouni Engineering department Higher Colleges of Technology (HCT) Ras Al Khaimah, UAE [email protected] Dr. Munther Gdeisat Engineering department Higher Colleges of Technology (HCT) Ras Al Khaimah, UAE [email protected] Step-by-step methods to properly size an off-grid photovoltaic (PV) system along with the estimation of lifecycle greenhouse gas (LC GHG) emissions of various power plants were attempted. The methodology focused on an average individual and then scale up the results to a household, a community, or the entire country. Given the high per capita energy of the United Arab Emirates (UAE), the main goals of studying an off-grid PV system in combination with a suitable energy storage system were 1) to smooth out the intermittent solar power, 2) to defer part of the peak load to a time when it is needed most, and 3) to urge policy makers and investors to prepare for the near future energy transition. The current real per capita energy consumption, average household size, and total population data were utilized to conduct this study. Therefore, overall results revealed that with an average panel generation factor (PGF) of 5.74, 46 panels would suffice in conjunction with 35 batteries of 48V or 140 batteries of 12V to satisfy the daily energy needs of an average resident. Results also showed that, by switching to the abundant and cheap solar energy, the current GHG emissions would likely be cut down by eleven (11) times. Notes:

Economic development is based on a reliable and cost effective energy supply. To sustain their economic growth, emerging countries need a dependable Distributed Generation (DG). DG is an efficient way to reach energy security by minimizing power losses in long and aging transmission lines. Due to the inherent complexity of electricity systems, this paper proposes to use a System Dynamics (SD) modelling approach to investigate the links between electricity supply and demand, population growth, and real climatic parameters in Niamey, Niger. Some of the variables utilized in this study were the local solar radiation and wind speed. Results proved that: (1) the current population will double in the horizon 2036 under the actual birth and death rates; (2) the highest summer electricity demand in the year 2015 was 217 MW; (3) electricity supply can be far higher than demand by implementing a 50 MW Renewable Energy Sources (RES) in conjunction with a 10 MW Energy Storage System (ESS); and (4) through a sensitive analysis, Niamey and neighboring vicinity would reach energy independence from 2017 to 2055, and even beyond.

Large-signal Stability of a Droop-controlled Microgrid Through Simplified Stability Conditions Alessandro Labella, Student Member IEEE, Daniele Mestriner, Student Member IEEE University of Genoa - Dept. of Electrical, Electronic, Telecommunications Engineering and Naval Architecture, Via Opera Pia 11a I-16145 Genoa, Italy [email protected] The control logic of a Microgrid (MG) represents one of the most important topic in power system engineering research. The most common and well-known control logic is represented by the droop one, that allows each MG source to share the power request and to participate to the frequency and voltage controls. In order to reach this goal, the stability of this control logic is fundamental and it is important to understand if a determined working point can be reached. In this paper a new stability condition, based on a mathematical framework and with some simplifying assumptions is presented. The proposed approach has the advantage of being a fast calculation that can predict the reachability of a particular working point that reflects a particular load request without using numerical algorithm or software simulators. The proposed methodology is finally validated with two simulations realized on PSCAD-EMTDC.

This paper examines policy in the Nigerian Electric Power Sector (NEPS) to cut transmission losses (TL) and improve capacity factor (CF) to 5% and 90%, respectively. A System Dynamics (SD) model developed in STELLA software package was employed to analyze this policy. Secondary data were sourced from: a) National Control Centre (NCC); b) Nigeria Electricity Regulatory Commission (NERC); and c) National Bureau of Statistics (NBS). Two scenarios were considered, the pre-privatized and improved scenarios. Results showed that at TL of 5% and CF of 90% i) electricity outages would be reduced by about 17.84% from 2010 to 2050; ii) over the study period a capacity of 473 MW (about 94.6 MW/year) would be fed back into the system; iii) transmission losses of 3,400 GWh would have been curtailed by 2050; and iv) cutting down TL and improving CF alone in NEPS will not totally curtail electricity outages and deficiencies in NEPS. Therefore, the study recommends that increasing generating capacity (MW) would go a long way in curbing electricity deficiencies. Renewable energy sources could be a better choice. Further studies are recommended in this regard. It was proven by the study that a system dynamics modelling approach is suitable for examining long-term behavior and dynamic feedback in Nigeria's electricity sector Notes:

Portable Robot for Cleaning Photovoltaic System Amna Al Baloushi, Maryam Saeed, Shaza Marwan, Shiaikha AlGghafri, and Yacouba Moumouni Department of Electronics Engineering, The Higher Colleges of Technology, Ras Al Khaimah, United Arab Emirates. Email: [email protected]

With growing costs of electricity and concern for the environmental impact of fossil fuels, implementation of eco-friendly energy sources like solar power are rising. One of the major methods for harnessing solar energy is through the utilization of photovoltaic (PV) panels. However, accumulation of dust and debris on PV panels has the potential to considerably reduce overall efficiency of the system. United Arab Emirates (UAE) is located in the Saharan desert which has an abundance of sunlight and open space appropriate for solar energy applications. The main problem the country faces is dust gust and little rainfall. As a direct consequence, solar panels must be often cleaned because dust reduces the efficiency of PV panels. Current labor-based cleaning methods of photovoltaic arrays are expensive and requires a huge amount of water. This paper proposes a new design and implementation of a Portable PV Cleaning Robot System (PPVCRS). Results showed that with the implementation of the PPVCRS, 1) the overall Solar PV array efficiency has increased; 2) more free and renewable energy was harnessed; 3) overall water usage was cut down; and 4) a significant economic benefits to the country was noticeable because less money was spent on labor and water.

World electricity demand is rapidly overtaking the power supply. Solar cell power is an alternative method of power generation. This paper focuses on designing a smart greenhouse using two power sources, one from the normal grid and another from the solar panels, in order to reduce the required energy for the house. Furthermore, by depending on the sun as a renewable source of power, it provides 'clean' energy. The house design consists of three important parts: the house construction, the solar system, and the use of smart applications. First, the house's construction and orientation is designed to reduce heat transfer and save more power. The construction materials of the wall, roof, ground and windows were selected for their favorable thermal mass and properties. Furthermore, the house is built with an East-West orientation with north and south facing windows. The second part employs an active solar technique using photovoltaic panels. A Solar PV system using photovoltaic cells converts sunlight into electricity, which provides the house with the necessary LED lights. The third part involves the use of smart applications, which are operated by solar power. These applications are as follows: solar curtains which can be opened at sunrise and closed at sunset through the use of a sensor that detects the sunlight when the sun rises and sets. A timer is added to the system to control the time that the curtain opens and closes in case the user wishes to select a different time for this operation. A sound system with different music sounds, such as prayer supplication (duaa') for morning and evening are also included; a security system with an automatic warning device in case of break in that sends a message to the police station, the owner of the house and the security staff; entry and exit house application devices that produce a sound of citations on the main door when a person enters or exits the house; and finally, a prayer time device (Authan).

Implementation of Proportional-Resonant controller in an autonomous Distributed Generation Unit Preetha Sreekumar Department of Electronics Engineering Higher Colleges of Technology ADW, UAE [email protected] Ravichandran Danthakani Department of Electronics Engineering Higher Colleges of Technology ADW, UAE [email protected] Suhas P. Veettil Department of Electronics Engineering Higher Colleges of Technology SJW, UAE [email protected] The control of interfacing inverter in a renewable energy generation is critical for an autonomous generation unit, as the voltage stability in such a system is solely determined by the interfacing inverter. Traditional voltage controlled inverters implement PI controllers to track the reference voltage. However, the PI controllers require dc quantities to provide zero steady state error. Moreover, the performance of a single PI controller may be inadequate for a system with nonlinear loads. This paper presents the implementation of Proportional Resonant controller which provides zero steady state error with sinusoidal reference signal. Also, PR controllers may offer better performance and less computational complexity for system with nonlinear loads. The proposed PR implementation has been tested using MATLAB/SIMULINK based simulation studies. Notes:

Utilizing Fuel Cell Technology for Dubai Roads and Transport Authority (RTA) Aziz Al-Mahadin Aviation Engineering Department, DBM Higher Colleges of Technology, Dubai, UAE [email protected] Mohamad Y. Mustafa Institute of Buildings, Energy and Material Technology UiT The Arctic University of Norway, Narvik, Norway [email protected]

The need for developing environmentally friendly and sustainable energy sources is globally evident. This is due to two main reasons: Fossil fuels will continue to supply energy demands for only a few more decades and the amount of pollution generated due to fossil fuels is exceeding acceptable limits. One very promising clean energy converter is the fuel cell (FC). Fuel cells have the ability to convert the chemical energy of their feed fuel to electricity through a chemical process without involving combustion, which significantly reduces harmful emissions such as NOx. Fuel cells generate absolutely no harmful emissions when their fuel supply is pure hydrogen and they are more efficient than internal combustion engines. This research will investigate the feasibility of utilizing fuel cells in the public transportation system of Dubai operated by the Roads & Transportation Authority (RTA), in order to gradually replace transportation fleets running on fossil fuel engines to engines running on pure hydrogen. The Proton Exchange Membrane (PEM) fuel cell is one of the leading technologies which has started to replace internal combustion engines. However, technology development, cost, durability and lack of relevant infrastructures are the biggest challenges to the implementation of FC. Notes:

Box 26666 Sharjah, UAE [email protected] Rached Dhaouadi, Senior Member, IEEE Department of Electrical Engineering, College of Engineering, American University of Sharjah P.O. Box 26666 Sharjah, UAE [email protected]

This paper presents a detailed model of a PV panel to study the effects of atmospheric conditions including local solar intensity, temperature, and dust. The objective is to quantify the dust accumulation rate and to determine the daily loss of energy output caused by dust accumulation. A numerical model is proposed to estimate dust accumulation on the surface of a PV panel. The model is developed by formulating the time varying dust coverage as a Poisson distribution with a constant arrival rate which depends on the current location. The model is validated through numerical simulation over a one-month period. The results can be used to study and predict the efficiency of PV modules over an extended period of time.

Biogas Production from Different Types of Cow Manure Mohamed Abdallah, Abdallah Shanableh and Mohamad Adghim Department of Civil and Environmental Engineering. University of Sharjah, Sharjah, UAE Chaouki Ghenai Department of Sustainable and Renewable Energy Engineering. University of Sharjah, Sharjah, UAE Suhair Saad Al Rawabi Dairy Company Dubai, UAE Animal waste generated in farms of developing countries is usually handled through stockpiling and direct application to soil. However, there are negative environmental impacts associated with those practices, mainly contribution to global warming, eutrophication and odor. Anaerobic digestion is one of the well-established technologies that capture the energy in the waste, including animal waste. In this research, manures from different types of cows typically present in dairy farms were collected and tested for its biochemical methane potential (BMP). The test was conducted on five categories of cows, including: (1) high cows; regularly milked cows, (2) dry cows; pregnant cows, (3) fresh cows; to be milked for the first time after their delivery, (4) young cows (Y1); cows younger than 18 months, and (5) young cows (Y2); cows younger than 7 months. Those cows differ in age, weight, digestion/metabolic processes and feeding diet, which lead to variations in biochemical characteristics, and consequently biogas potential, of the produced manure. The methane yield was found to be highest in the manure of fresh cows (216 L-CH4 kg-1 VS), followed by Y1 (208 L-CH4 kg-1 VS), high (196 L-CH4 kg-1 VS), dry (160 L-CH4 kg-1 VS), and Y2 (148 L-CH4 kg-1 VS) cow manures. The carbohydrates, lipids, and proteins were measured for each manure type to determine their effects on biogas production. Furthermore, those parameters were tested for correlation with the measured biogas production using Kendall's Tau approach. The analysis showed that the lipids reduced the overall biogas production from manure, followed by protein and carbohydrates. Higher lipid and protein contents lead to lower biogas potential, while higher carbohydrates content resulted in higher biogas production.

A Feasability study of roof-mounted grid-connected PV solar system under Abu Dhabi net metering scheme using HOMER Issah M. Alhamad Mechanical Engineering Department United Arab Emirates University Al Ain-UAE The electric power consumption per capita in UAE is very high with almost 11,264 kWh per person in 2014. The country mainly relies on oil and gas for producing electricity. Abu Dhabi emirate consumed 62,979,070 Mega-Watt hour (MWh) of electricity in 2016 with only 30,867 MWh produced from renewable resources. The carbon footprint of electricity generated from fossil fuels was estimated to be almost 26.5 million tons of Co2 equivalent in 2014. Therefore, the need to expand the power generation from clean renewable resources is of high importance. This study measures the feasibility of utilizing PV panels on the roof top of a mixed-use building while connected to the power grid of Abu Dhabi emirate under the net metering scheme. The building electric energy consumption was studied using Carrier HAP software, then HOMER software was used to design and simulate the grid connected PV system. The results showed that a 25 kW PV panels and a 25 kW invertor with an initial cost of $ 41,250 (150,000 AED) can produce 48,864 kWh/year and can feed the grid with 18,421 kWh/year. The net present cost (NPC) was found to be $ 98,544 (362,000 AED) and the levelized cost of electricity (LCOE) was found to be $ 0.107 per kWh (39 fils/kWh). The attractive power generation numbers and costs associated with this PV system can confirm that its application is justified both economically and technically at Abu Dhabi emirate under net metering scheme.

Wind Energy converter systems require a sophisticated control structure to perform accurate and efficient power conversion. The converter modulation is always a challenging topic. This Paper presents an efficient timing study of Space Vector Modulation (SVM) for Three Level Neutral Point Clamped Converters (3L-NPC). Various patterns have been proposed with different slot numbers and dwell time distribution. By increasing the number of slots, a faster digital signal processors (DSP) is required to ensure the efficient execution of the SVM algorithm. In this paper, a systematic method to select the SVM switching time in relation to the DSP sampling time is presented. Moreover, a new technique for constructing the switching patterns is introduced. The proposed calculations are verified analytically and through a detailed simulation of multilevel converter. The results demonstrate the critical relation between pattern selection, SVM switching frequency, and the DSP sampling frequency. Notes:

The Road Power Generation system is a new type of clean, green, unconventional source of energy. As it works by reusing the wasted energy that caused by the vehicles passing through the system, the kinetic energy can be converted to electrical energy. This process of reusing the wasted energy is considered as a low budget electricity production. Which can be used in powering roadway signs, street lights, and storage systems for back-up and emergency power. Road Power Generation (RPG) produces energy 24 hours a day. Millions of vehicles are traveling on our roads. The kinetic energy from these moving vehicles can be utilized in converting pressure mechanical energy into electrical energy. The method used to generate electricity nowadays in the UAE is based on petrol and nuclear. The RPG will help the economy by producing electricity at less cost than the petrol and nuclear. In this paper, an experimental approach is presented in order to prove the concept of operation of the road power generation system as a usable form of energy. Notes:

Calay Institute of Buildings, Energy and Material Technology UiT The Arctic University of Norwa, Narvik, Norway

Heat engines, such as internal combustion engines, have significant adverse effects on the environment due to their heat and harmful emissions. In addition, they are dependent on energy from fossil resources, which are depleting rapidly and they are not being properly utilized due to the relatively low efficiency of heat engines usually expressed by Carnot's efficiency. The low temperature direct conversion process, in which hydrogen is chemically oxidized, is one of the best alternatives to heat engines. In this process, the heat emitted to the surroundings, or in driving the reaction, is kept to a minimum. This method would meet the pressing need of humanity to find power generation and utilization techniques that are more efficient and less harmful to the environment than conventional power generation methods. This will also help to conserve energy resources, and at the same time, protect the environment by reducing the amount of harmful emissions, and thermal loading i.e. greenhouse effects. In fact, the fuel cell technology can overcome these difficulties and pave the way for utilizing different sources of energy. This paper investigates the possibility of utilizing fuel cell technologies in Dubai public transportation and in particular the rail systems. This matter is critical for Dubai since it is one of the fastest growing cities. Recently Dubai has launched the Clean Energy Strategy, which aims to make Dubai a global center of clean energy and green economy. The utilization of fuel cell technology is very important for Dubai since it has the potential to increase energy efficiency of the transportation sector, increase energy security, improve environmental quality, and position Dubai as a leading city in advanced rail transportation.

An assessment of energy efficiency potential with a subsequent policy program was proposed. The scope of the study was the residential lighting, refrigeration, cooling, and ventilation in Lomé, the capital city of Togo. This research sought to assess inefficient installed light fixtures along with household appliances and to estimate ways to save energy by utilizing both brand new and more efficient electrical devices. A survey was conducted not only to assess the appliances, but also to identify their status as "brand new" or "used" items. The results were analyzed with the Statistical Package for Social Science (SPSS) software and the 2016 spreadsheet. In addition, a real-time monitoring experiment was conducted on used and brand-new televisions (TVs) and refrigerator-freezers. The potential of energy efficiency was evaluated under two policy scenarios: 1) New Policies and 2) Sensitivity Analysis. The results revealed predominantly less efficient appliances in Lomé's housing sector. Results also showed that by opting for only new and efficient appliances, Togo would save a huge amount of energy over the next two decades or so.

Hydro-power energy has been selected as an alternative source of energy that is sustainable, functional and economically feasible. A hydro-power plant was designed to provide electricity to a mid-size farm that requires 50 kW power. The hydro-power power plant was designed using micro-Pelton wheel turbines and a pumped-storage reservoir as a water energy source due to the lack of water dams and river streams in UAE. The design focus of the hydro-power was on the turbine section of the plant that consists of a unique blade shape of turbine bucket that was able to extract maximum energy from the water flow. To verify on the functionality of the hydro-power plant, theoretical calculations have been done to determine the output electrical power and the overall efficiency, which have been obtained to be 47.2 kW and 80% respectively. This indicates the designed micro-Pelton wheel turbines are able to produce the required energy of the farm with a high overall efficiency. The feasibility of the project has been evaluated as well to conclude that the designed hydro-power plant is found to be economically feasible based on the calculated simple payback period of less than two years.

The Proposed Use of Generalized Regression Neural Network to Reduce Risk of Piles Failure Prior to Construction A. K. Alzo’ubi Civil Engineering Department Abu Dhabi University Al Ain, United Arab Emirates [email protected] Farid Ibrahim Computer and Information Technology Department Abu Dhabi University Al Ain, United Arab Emirates [email protected]

In the UAE, continuous flight auger piles (CFA) are the most commonly used type of foundations to construct high rise buildings, bridges, and other heavy structures due to the high groundwater table and the weak soil/rock layers near the ground surface. To minimize the risk of failure, of these CFA piles, mandatory expensive field tests need to be performed and the most important one is the Static Pile Load Test (SPLT). To minimize number of tests required for a particular project in the field, this paper proposes using General Regression Neural Network (GRNN) to predict the pile performance ahead of any test. The data collected from thousands of loading points in over one hundred projects from Dubai, Abu Dhabi, and Al Ain cities are used to develop a GRNN capable of predicting SPLT curves with reasonable accuracy. The friction angle, unconfined compressive strength, depth, soil type, groundwater table, pile's diameter, and pile's length are the parameters that need to be input to predict the load-displacement curves of the SPLT. In this research, we propose to show that this approach can complement conventional SPLT and provide engineers with sufficient insight on the pile performance ahead of the actual test

Developing solutions for dealing with water and food scarcity Atmospheric water generator and urban farm tower Camilo Cerro, Assistant Professor College of Architecture, Art and Design American University of Sharjah, Sharjah, UAE [email protected] For the first time in world history, more than half of the world population lives in towns and cities. According to the United Nations, urban areas are expected to absorb most of this population growth over the next four decades. With the world number of urban inhabitants estimated to grow from the present 3.9 billion to 6.3 billion people by 2050, the vast majority of this surplus will be living in slums with inadequate or non-existent water, health or sanitation systems. Today more than 156 million urban dwellers, live without immediate access to water. In places like Mumbai India, where the average yearly humidity is of 75%, the problem of water scarcity can be solved with minimal infrastructure with the use of atmospheric water generators. There are 3.1 quadrillion gallons of water in the atmosphere at any given time. While the average humidity in your home or office is 50%, an atmospheric water generator can produce water from humidity as low as 35%. This means in a place like Mumbai, a single atmospheric water generator can produce up to 5000 litters of water a day. The production of this amount of water in multiple locations within a slum has the potential to solve the water crisis by producing clean, filtered, free, accessible water and by doing so eliminating health and sanitation issues. The proposed project in this paper will address the use of this technology while at the same time using it to solve nutrition problems in the same slums by serving also as a water resource for urban farms designed to produce fruits, vegetables and mushrooms in the same structure that houses the atmospheric water generator. The proposed tower will grow hydroponic produce within the slum, cutting transportation and packaging costs. The idea is to create a network of interdependent facilities that directly serve large numbers of people through a process of urban acupuncture producing services that require minimal maintenance and the possibility of creating local jobs while helping solve the water and food crisis in slums in the developing world.

Atmospheric Pollution with Heavy Metals at Tabouk City-KSA Anwar Jiries Faculty of Science, Mutah University Karak, Jordan Anf Hanna Ziadat Civil Engineering Department, Abu Dhabi Men’s College Higher Colleges of Technology, Abu Dhabi, U.A.E Rehab Al-Atwi Faculty of Science, Chemistry Department, Tabouk University Tabouk, KSA Air pollution with heavy metals at Tabouk City in the Kingdom of Saudi Arabia was evaluated using street dust and tree bark as indicators. Air pollution with six heavy metals (Cu, Zn, Ni, Mn, Fe and Cd) from the city of Tabouk City were evaluated by collecting street dust and tree bark samples from residential areas, the city center, and a remote site for results comparison. The results showed that higher air pollution was found at the city center in comparison to the residential areas using tree bark and street dust samples. The abundance of analyzed heavy metals concentration in the descending order for street dust were Fe > Mn> Zn > Cu > Ni > Cd. The city center and residential areas showed similar trends due to the same pollution source which is traffic emission in this case. The concentration of heavy metals in descending order from tree bark samples were Fe > Zn > Cu > Mn> Ni > Cd reflecting the existence of air pollution for years and at the earlier stages of the tree growth. It can be concluded from this research that the major source of air pollution in the city of Tabouk is majorly due to traffic activities as no major industries are located within the investigated area. Street dust is commonly attributed to the transportation of heavy metals with prevailing wind direction in the study area. The results of heavy metal air pollution found in this study were compared with some other cities around the world. The levels of the metal ion concentrations were generally below the mean concentration values in comparison to the commonly known air polluted cities of the world. Notes:

Therefore, there is a need to understand the factors that significantly contribute to injuries at such places. These factors can fall under different dimensions in traffic safety such as environmental conditions, road user behavior, traffic police enforcement, road design and crash characteristics. The paper will analyze the factors related to crash characteristics and traffic signal operation that affect the likelihood of accident severity located at intersections. The data for intersection accidents in Abu Dhabi from 2013 to 2016 were used in this analysis. Ordinal logistic model was considered for the analysis to account for the ordinal nature of severity levels. Several diagnostics tests of the model were preformed such as parameters evaluation, overall model evaluation and prediction accuracy. For parameter evaluation, out of 11 independent variables, 6 were non-significance and dropped from the model. Most of the non-significance variables were related to the driver at-fault details. The results of the final model showed an overall good fit based on a p-value less than 0.05, as well as a good accuracy of prediction 84.8%. Finally, Odds ratios were estimated to interpret the final results of the model.

Assessment and Data Assimilation of Agricultural Drainage Water for Reuse in Irrigation Purposes Walaa Assar Environmental Engineering Department. Egypt-Japan University of Science and Technology. New Borg Al-Arab City, Alexandria, Egypt. [email protected] Ayman Allam Civil Engineering Department, Faculty of Engineering. Kafr Elsheikh University, Egypt. [email protected] Ahmed Tawfik Environmental Engineering Department. Egypt-Japan University of Science and Technology. New Borg Al-Arab City, Alexandria, Egypt. [email protected] Agricultural drainage water (ADW) represented an excellent source for irrigation purposes where the water quality in terms of pH, dissolved oxygen (DO), Turbidity, total dissolved solids (TDS), chemical oxygen demand (COD), nitrate (NO3-N), ammonia (NH4-N), total suspended solids (TSS), volatile suspended solids (VSS), total organic carbon (TOC), inorganic carbon (IC) and total carbon (TC) along El-Salam canal were assessed. The results revealed that all parameters were in accordance for reuse in agricultural purposes except dissolved oxygen. This was mainly due to dumping of pollutants into the canal. The COD was varied from 4.66 to 32.6 mg/l. This is mainly due to discharge of domestic wastewater which cause a serious depletion of dissolved oxygen (DO=3.98 mg/l). The NO3 was quite low and varied from 0.49 to 1.89 mg/l while the ammonia concentration along the canal was largely varied from 1.43 to 6.33 mg/l. This indicates that the nitrification-denitrification could be occurred along the canal resulting a deterioration of water quality along the canal. However, the ammonia and nitrate are represented a good soil conditioner and minimizing the usage of chemical fertilizers. Relative (10 % and 40%) and constant standard deviations (0.10 and 4) for the discharge were applied in the MIKE 11 data assimilation for pump stations no. 1 and 2 which was not significant at T-test value (p>0.05).

Modelling the relationship between the energy, carbon and water efficiency of the most sustainable corporations in the world Alina Barbulescu Higher Colleges of Technology Sharjah, United Arab Emirates [email protected] Simona Mascu Academy of Economic Studies, Bucharest, Romania [email protected] Narcis Duteanu Politehnica University of Timisoara, Timisoara, Romania [email protected] The present study addresses the amount of economic output possible at a given level of energy supply, carbon (greenhouse gas emissions), water use and waste generated recorded in 2014 by the 100 most sustainable corporations in the world. Assessing the long-term sustainability on this scale requires fundamental research in the global industrial system. Thus, in this article, we used an integrated approach that assesses how green businesses operate and we analyzed the relationship between energy, carbon and water, based on the data from the top 100 sustainable companies in the world. We propose two models, for the dependence of carbon on energy efficiency and carbon on energy and water efficiency. They are generalized linear models (GLM) because they reduce to linear models by taking logarithms. The results of our models prove the existence of high correlations between the carbon efficiency, water efficiency and energy efficiency. Comparing the models, it results that the water has a smaller influence than the energy on the carbon efficiency

Green Blocks Made of Recycled Waste Elgaali Elgaali 1 , Abdulla Alsharid 2, Ahmed Julfar 3 Dubai Men’s College ([email protected])

Recycled aggregate (RA) is widely used in construction industry. These uses include road sub-base pipes bedding and back filling. This research shows the feasibility of producing sustainable blocks made of recycled materials. In this paper, the combined effects of recycled aggregate (RA) and recycled water (RW) on strength and durability of concrete blocks are presented and discussed. The test program involves the preparation of moderate strength concrete blocks out of recycled water and recycled aggregate obtained from construction waste. Twenty one mixes of concrete and 156 specimens were prepared. In the mixes 25%, 50%, 75%, and 100% of the fresh aggregate and water were replaced by recycled aggregate and recycled water. The effect of recycled aggregate and water on axial and flexural strength was found to be moderate but had a significant effect on durability. To enhance the durability and lower the carbon footprint (1000 kg/m3) of the recycled concrete mix, the OPC was replaced by GGBS. Three replacements, 25%, 50%, and 75% of OPC were tested. All the mixes achieved a reasonable enhancement on the strength and durability of the blocks. In general making blocks of recycled materials is feasible. GGBS replacement is recommended for future work to enhance the strength and durability.

Mapping of Dewatering Impacts on Ground Water and Soil Quality Using GIS Elgaali Elgaali1 , Majid Akram2 1 Dubai Men’s College ([email protected]) Dewatering is a technique used to lower the high-water table for safe construction purposes. On the long run, this process has been suggested to have negative impacts on groundwater/soil quality. This research deals with mapping the groundwater/soil quality (salinity) in the Silicon Oasis area in Dubai from the years 2005 to 2016, using GIS technology. The main goal of this project is to quantify and visualize the impacts of dewatering on the groundwater/soil quality. The field measurements of water table, groundwater qualities, soil salinity levels, and ground locations and elevations are used as a ground truth data for the analysis. The temporal and spatial variations of the groundwater/soil quality, in the study area, were determined. Then the impacts of the dewatering were quantified and evaluated. Thematic maps showing the variation were generated. Finally, the efficiency of the GIS technology in mapping the dewatering impacts is outlined.

Use of Aerial Photography and GIS in Estimating Urban Lawn Irrigation Requirements Elgaali Elgaali Civil Engineering, Dubai Men’s College Higher Colleges of Technology, Dubai, UAE ([email protected]) Urban lawn irrigation is an important component in urban water budgets. The water requirement both timing and volume are important and need to be accurately estimated for both helping landowners improve the amount of water they apply as well as to estimate the efficiency of the system. The lawn irrigation estimation process is heavily influenced by having accurate land-cover type areas. In this study land-cover data extracted from aerial photographs were used to monitor and estimate urban lawn irrigation water requirement (IWR). Five landcover categories (grass, trees, impervious, soil, and water) were digitized from aerial photographs using GIS. Landcover information was introduced into a consumptive use model to estimate lawn irrigation consumptive use. A demonstration of aerial photographs based lawn IWR estimation was performed on an area in Denver, Colorado. As part of the GIS dataset that was created, a lot of additional information was generated such as location of the parcels (address), impervious areas, canopy of trees, canopy of trees over grass, and canopy of trees over impervious areas. Some studies have been conducted on how to use random sampling to estimate the total area of lawns in urban areas. Combining this statistical sampling with GIS and aerial photography was found to be a cost effective methodology for assessing lawn IWR in urban areas.
