Chair's Message

I am proud to be working with faculty who continue to strive for excellence in academics/research, regional development and service. Since the fall semester 2008, departmental programs and activities have significantly evolved. The faculty and department staff has been working hard to adapt and improve programs based on recommendations of an already successful ABET accreditation visit of our Bachelors programs in Mechanical Engineering Technology, Electronics Engineering Technology, Manufacturing Engineering Technology, and Nuclear Engineering Technology. At the same time, the

department developed a new Master of Science in Engineering Systems that is rations in the following areas: Mechanical Systems,

Electrical Systems, Construction Management, and Engineering Management. These initiatives have received overwhelming support from our constituencies.

being offered with concent

In order to increase the quality of service provided to our students, the department has implemented a new advising system; whereby each student has an assigned department faculty advisor for the duration of study. All departmental teaching laboratories have been, and continue to be, updated with state-of-the-art equipment and instrumentation. A new metrology lab has been created to enhance the laboratory experience in all programs. Two additional laboratories have been developed to support our Construction Engineering Technology program.

We have increased the capacity of our department offerings by hiring two tenure track faculty members and a lecturer in Construction Engineering Technology. A tenure track faculty member joined the faculty of our Mechanical Engineering Technology program in June 2008; and another faculty member is expected to join our Engineering Systems program in fall 2009.

The faculty have been communicating their research at a number of international and national conferences, as well as publishing in refereed journals – the number of which has increased more than 60% last year. Research funding secured by faculty and research collaborative projects continue to increase. Collaboration with industry to support students’ learning through internships, co-ops, student-oriented research as well as the development of new technologies is significant. Looking forward, the Department of Engineering Technology has initiated a new vision stressing a “Systems Engineering” emphasis. This emerging field of Engineering is being emphasized worldwide in part due to globalization and to companies requiring engineers to be technically proficient, superior communicators, and well versed as systems integrators.

As we say “Enjoy your career!” to our graduating students, we welcome our incoming students to their Department.

A System for Automatic Detection of Deceleration in Moving Vehicles

Kenneth Marlowe, Bryan Cotanch, and James Parker are senior ELET students who obtained approval from the University Patent Review Committee to receive funding to file a patent. This is the first group of students, undergraduate or graduate, to receive approval from the Review Committee.

This invention will constantly monitor the acceleration and deceleration of any vehicle and will activate brake lights when deceleration occurs without the use of conventional braking. This invention will monitor rates of acceleration to determine if a skid is imminent. As the vehicle approaches the skid threshold, the accelerometer will be monitoring the rate of acceleration and the microcontroller will compute the data and activate a warning system to alert the driver that the vehicle is approaching hazardous rates of acceleration. The invention will monitor the amount of g-force incurred during collisions for rear-impact airbag deployment. The airbag will not be activated immediately, but will deploy after the head has started moving forward again.

National Association of Homebuilders

The student chapters of NAHB and AGC combined their efforts to build a habitat for humanity storage unit. The building was

constructed at the Discovery Park by student volunteers and delivered to the home site on February 28. Construction students have volunteered to assist both Habitat for Humanity and Hearts for Homes with projects to gain construction experience.

Hardware-Software Codesign of a JPEG2000 Watermarking Encoder Jose Antonio Mendoza

Dr. Elias Kougianos, Major Professor

JPEG2000 is rapidly becoming the next generation standard for the transmission of images over the Internet. Due to its added complexity compared to the current JPEG standard, hardware implementations for Digital Rights Management (DRM) are scarce. In this work, a hardware-software codesign methodology is presented that allows rapid development and prototyping of DRM algorithms for JPEG2000. A field Programmable Gate Array (FPGA) is used in combination with Matlab/Simulink in a hardware-in-the-loop approach to demonstrate the effectiveness of this method. A perception-based visible watermarking algorithm was implemented and the balance between handling complex tasks in software while off-loading the actual processing in hardware allows for exhaustive design space exploration, which is difficult in hardware-only methodologies.

A Study of the Laser Direct Writing for All Polymer Single-Mode Passive Optical Channel

Waveguide Devices

Cold-Formed Steel Bolted Connections Without Washers on Oversized and Slotted Holed

Ibraheem Sheerah Bradley W. Borden Dr. Cheng Yu, Major Professor

Dr. Shuping Wang, Major Professor The current North American Specifications for the Design of Cold Formed Steel Structural Members, NASPEC 2007, doesn’t comprehend provisions for such connections. The NASPEC shows four modes of failure of the cold-formed steel sheet bolted connections, which include: sheet shear failure, sheet bearing failure, sheet tensile failure, and bolt shear failure. The bearing failure of sheet and the shear failure of sheet were considered in this study. Structural performance of bolted connections between cold-formed steel sheets of single and double shear, without washer, on oversized and short slotted holes, and under shear and bearing stresses was experimentally examined. The influence of ductility on the behavior of the cold-formed steel sheets bolted connections was considered. A new proposed method resulting from this study was compared with the AISI approach presented in NASPEC 2007 and the University of Waterloo approach.

An efficient and cost-effective method of maskless laser direct writing of all polymer single-mode passive optical components for use in optical integrated circuits (OICs) was studied. The polymeric thin films were characterized to find the index of refraction at wavelengths of 633 and 1550 nm and to acquire photoresist spinner calibration curves with various spin rates for determining thin-film thickness. Simulations were performed to determine dimensions for single-mode optical channel waveguide components and predicted the loss of Y-branch bends and determined the optimal width and length for complete coupling to occur in a waveguide directional coupler. Characterization of the resulting interconnection components showed the waveguides to be single-mode and to have losses of 0.79 dB/cm, which are suitable for use in OICs.

Factors Influencing Horizontal Cracking in Continuously Reinforced Concrete Pavements Effects of Minimum Quantity Lubrication in

Drilling 1018 Steel Elias Sudoi Vasim Shaikh Dr. Seifollah Nasrazadani, Major Professor

Dr. Nourredine Boubekri, Major Professor

This research presents the results of an experimental investigation to identify the significant factors influencing concrete/rebar bond failures resulting in cracking of continuously reinforced concrete pavements. Water to cement ration, rebar temperature at the time of concrete pouring, and rebar surface condition (as-received vs. corroded) were factors investigated in this research because they have a significant influence on the rebar-concrete bond strength. The 28-day shear strength measurements showed an increase in rebar-concrete bond strength as the water-to-cement ration (w/c) was reduced from 0.50 to 0.40. There was a reduction in the peak pullout load as the rebar temperatures increased from 14

A common goal for industrial manufacturers is to create a safer working environment and reduce production costs. One common method to achieve this goal is to drastically reduce cutting fluid use in machining. Recent advances in machining technologies have made it possible to perform machining with minimum-quantity lubrication (MQL). Drilling takes a key position in the realization of MQL machining. In this study the effects of using MQL in drilling AISI 1018 steel with HSS tools using a vegetable based lubricant were investigated. A full factorial experiment was conducted and regression models were generated for both surface finish and hole size. Lower surface roughness and higher tool life were observed in the lowest speed and feed rate combination.

oF to 252oF for the corroded and non-corroded rebar experiments. The corroded rebar pullout test results showed a 20-50% reduction in bond strength compared to the non-corroded rebars. Outstanding Students

Mechanical Engineering Technology – John Price The demand for low power consuming circuits is increasing with the requirements for personal computing devices and wireless communications equipment. We propose methodologies and techniques to achieve variability, power, performance and parasitic aware circuit designs. Three approaches are proposed: the single iteration automatic approach, the hybrid Monte Carlo and Design of Experiments (DOE) based approach, and the corner based approach. Widely used mixed signal circuits such as Analog to Digital Converter (ADC), Voltage Controlled Oscillator (VCO), Voltage Level Converter and Active Pixel Sensor (APS) have been designed at nano-scale CMOS and subjected to the proposed methodologies. We have also explored the application of dual-oxide and dual-threshold techniques at circuit level in order to achieve power (including leakage) minimization.

Inorganic-organic hybrid polymers make possible the combination of useful organic and inorganic characteristics within a single molecular-scale composite. They can be synthesized to have a controllable combination of the properties such as optical, electrical, and mechanical performances by combining the properties of both organic polymer and inorganic compounds. Inorganic-organic hybrid polymers with specific optical properties have been demonstrated. However, the uses to obtain significantly improved properties with opportunities for applications are only now being realized. The goal of the proposed research is to investigate the optical property of the selected inorganic-organic hybrid polymers and conduct the performance study at material and device level, with the focus on optical interconnects applications.

Shear Resistance of Cold-Formed Steel Stud Walls with Wider Range of Options in Steel Sheathing –

Phase Two

In cold-formed steel construction, bolted connections without washers on oversize holes or short slots may significantly expedite the building process and lower the cost without loss of the desired strength. However, current design

Dr. Cheng YU, PI Sponsored by American Iron and Steel Institute specification does not include provisions for such connections,

and washers are required in oversize holes or short slots.

The research objective of the Phase 2 research is: 1. To verify and propose revised shear strength values in AISI

S213 for 18-mil sheet steel walls with 2:1 aspect ratio and 6” fastener spacing at panel edges; and 27-mil sheet steel shear walls with 4:1 aspect ratio and 6”, 4”, 3” and 2” fastener spacing at panel edges;

The proposed research aims to experimentally investigate the three failure modes in bolted connections that the non-washer and oversize perforation configuration would affect directly. The three failure modes include shear failure, bearing failure, and the fracture failure in the net section of the connected sheet. The research project consists of two phases. In Phase 1, the shear and bearing failures were studied. In Phase 2, the investigation on the bearing and shear failures will be extended to more material thicknesses, bolt diameters, different slot orientation, and the fracture failure. The test matrix includes a full range of connection configurations covering steel thickness from 118 mil to 33 mil, single and double shear, single bolt and two bolts, ASTM A307, A325 bolts with diameters from ¼ inch to 5/8 inch, and low-ductility steels in the sheets. The research focuses on the application of A307 and A325 bolts with ½ inch diameter.

2. Based on the tests results of Phase 1 and Phase 2, the deflection equations in AISI S213 will be evaluated and revisions will be made if needed to accurately predict the deflections for sheet steel shear walls;

3. Determine seismic detailing requirements to assure satisfactory performance of a 6’-wide steel shear wall with a 2’-wide and a 4’-wide steel sheet sheathing.

Eccentrically Loaded Cold-Formed Steel Wall Stud Walls

Photonic WDM Digital Beamformer Dr. Cheng Yu, PI Dr. Shuping Wang, PI Sponsored by Nucor Corporation

Sponsored by the US Navy STTR through Agiltron, Inc.

Cold-formed steel (CFS) wall studs may be subjected to eccentrically loading for some specific joist bearing configurations in real applications. The eccentricity may cause unexpected failure modes on CFS studs and the potential excessive rotational displacement of the bearing seat may also cause damages on both the studs and the joists.

Analog beamformers require customization and trades in radar performance due to bandwidth limitations, insertion losses, need for a frequency downconverter, parameter stability over time/ environment, and the need for calibration. Resultant designs have added complexity and cost limiting radar performance and countermeasures options. We propose a wavelength division multiplexing (WDM) based photonic digital beamformer that offers significant improvement in phased array radar performance. The proposed beamformer provides rapid time delays of picoseconds to microseconds for mbeam shaping and steering and can be used with any frequency phased array radar.

The goal of this research is to study the behavior the CFS studs eccentrically loaded by the joists. Two specific subjects will be addressed:

1. The failure mode and axial compression capacity of CFS studs under eccentric loading;

2. The effect by various joist bearing configurations on the CFS studs.

Speed and ease of instrument operation, accuracy, reliability, ease of spectra interpretation are among many features that make FTIR an ideal technique for routine qualitative and quantitative characterization of materials.

Shear Resistance of

Cold-formed Steel Framed Shear Wall Assemblies for Mid-rise Construction

Dr. Cheng Yu, PI Sponsored by Worthington Industries

Possible applications of FTIR to paving materials include cement, paint, thermoplastics, epoxies, sealants, and lime. Practical applications of FTIR in determination of quality and uniformity of anti-stripping additives, curing membranes, epoxy materials, and cement will be investigated. In addition, quantitative analysis of anti-stripping agents in emulsions, cut-backs, and neat binders, as well as polymer content in asphalt binders will be explored. Separate practical protocol for each kind of analysis will be developed for identification and quantification for paving materials constituents. Results obtained by FTIR for a given analysis will be validated using at least one other appropriate technique of X-ray diffraction, X-ray fluorescence, Scanning Electron Microscopy, Energy Dispersive Spectroscopy, and Differential Scanning Calorimetry.

The objective of this project is to determine the nominal shear strength of 4 ft. by 10 ft. cold-formed steel shear wall assemblies for wind loads and seismic loads. The shear strength against wind loads will be obtained by monotonic shear wall tests and reversed cyclic shear wall tests will be employed to determine the shear strength against seismic loads.

The parameters taken into consideration in the test matrix include the fastener spacing pattern and the framing members. The monotonic tests will conform to ASTM E564-06 “Standard Practice for Static Load Test for Shear Resistance of Framed Walls for Buildings.” The reversed cyclic tests will use the CUREE protocol in accordance with ICC AC130 (2004) Section 5, and the nominal values will be based on the lesser of the peak load on the response envelop or the load at a deflection of 0.025h, where h is the height of the shear wall.

Results of this investigation could be directly implemented by fully training CST laboratory personnel on a one-to-one basis.

Dr. Seifollah Nasrazadani Sponsored by Texas Department of Transportation

Two major distresses in continuously reinforced concrete pavement (CRCP) in Texas are punchout and spalling. Spalling is a surface distress and rarely presents a structural distress. It is also well understood that spalling has more to do with the

The goal of this research is to provide a framework and facilities that will allow the designers of complex digital systems to select a technology and analyze system-level power-performance-area tradeoffs at an early stage in the design process. Within the scope of the proposed work lies the

coarse aggregate type used in concrete. Punchout is a serious distress in CRCP which needs to be repaired as soon as possible since un-repaired punchout can cause safety hazards to the traveling public. To address punchout issues, TxDOT made a few changes in the mid-1980s which included the use of thicker concrete slabs, stabilized subbase (either 6-in cement stabilized base or 4-in asphalt stabilized base) and tied concrete shoulders. These changes have been effective, substantially reducing the frequency of punchout. However, during the full-depth repair of what appears to be punchout, it was observed that there was a different form of punchout, which the above three changes did not appear to alleviate.

integration of device modeling, logic gate level power estimation, and behavioral and system-level simulation. The framework will be implemented as a toolbox in MATLAB/Simulink, thus allowing the use of extensive optimization, processing and visualization facilities built into MATLAB and providing the design engineer with a robust development and design exploration environment.

Dr. Kougianos collaborates with Dr. Saraju Mohanty from the Computer Science and Engineering Department at UNT and Dr. Rabi Mahapatra from the Computer Science Department at Texas A&M University. The three PIs jointly investigate design trade-offs among the functionality, power consumption and circuit complexity of next-generation complex digital designs using traditional or non-classical nanoCMOS processes.

Further evaluation revealed that this distress is caused by horizontal cracks in concrete at the depth of close to the longitudinal steel (mid-depth of the slab). This distress type was not acknowledged in the AASHO Road Test, and has not been well recognized by researchers and practitioners until recently.

DC BEST 2008 Competition Dr. Mitty Plummer Returns from French Tour

The Denton County Boosting Engineering, Science, and Technology (DC BEST) Robotics competition started on Saturday, September 12, 2008 with the Kickoff event which was held at the UNT College of Engineering. Theme for the game field competition was “Just Plane Crazy” and consisted of using robots to assemble airplanes and have them compete against each other.

During this Kickoff event, the rules of the upcoming robotics competition were explained, the game field demonstrated and the free robotics supplies distributed. Approximately 150 people attended this event with individuals from the College of Engineering serving as judges, referees and volunteers. Mall Day was held on Saturday October 18 at the Golden Triangle Mall in Denton. High schools were able to test their robots in the actual game field. Game Day was held at the UNT Coliseum on October 25. The robotics tournament was conducted throughout the day with the tournament competition winner being Marcus High School. The Best Award, which encompasses several activities that are aimed at a professional engineering career, was presented to Circle of Science, with Lewisville High School in second place. The three winning schools moved on to state level competition – TEXAS BEST – which was held, for the first time, at UNT in November.
