F01Horse Arena Water SprayerCody O’Loughlin, Mark Sharrar, Immanuel Sandryka, Ben Leitner, Sean ConwayThis project addresses a problem at the Tri-State Therapeutic Riding Center in Cleveland, TN where dust accumulates in their horse arena during therapy sessions. This creates an uncomfortable and dangerous work and therapy environment. The team developed the Dust Buster to respond to the client’s needs. The Dust Buster has made substantial improvements to Tri-State Riding Center’s therapy program. Not only does it provide a dust-free environment, but is also designed in such a way that children can receive therapy to multiple muscle groups by personally maneuvering the device around the arena.

F02Creating Art with PaintKeith Gregg, Mason Gregoire, Nina Rice, Chris RuhnerTA classroom in Catoosa county has 5 students who are considered to have profound disabilities. Two students require a wheelchair; the other three are mobile. All of the students have fine or gross motor delays. Their disabilities prevent them from accessing the general curriculum art supplies such as paint tools. They also have difficulty keeping paper and canvas steady during the art process. The student team developed a platform for these students to participate in art class when creating individual and group paint creations.

F03Soft Glow Block LightChris Broadhurst, Joey DeLoach, Kian Sandoval, Markeith WilliamsThe client spends his time creating personalized decorator items for gift shops. He recently designed a decorator block and a block clock made from a glass block, a string of Christmas Tree lights, a computer generated scene printed on laser printer transparency film, and a clock mechanism (for the clock) to make his decorator blocks. The bottom of the glass blocks have an opening that allow fitting of the clock mechanism and insertion of lights. The student team was tasked to design a light system that is aesthetically pleasing and incorporates all components in one unit so it is easy to use by the customer.

F04, and F05UTC Hammock Garden HangerChase Brown, Tanner Finch, Jared Thompson, Joshua Topham (F04, Team 1)

Sam Crockett, Matt Holliday, Nathan Merritt, Stan Settles, Alex Snyder (F05, Team 2)The Student Government Association (SGA) at the University of Tennessee at Chattanooga (UTC) desires to create a small park where students can hang their hammocks and study or socialize. The SGA is considering the space between Crossroads and Chamberlain Pavilion south of Brock Hall for the park. They are looking for a few

FRESHMAN DESIGN PROJECTS


hanging solutions and park layouts to present to the UTC administration to initiate the park. This team of students from the freshman Introduction to Engineering Design (IED) course in the UTC Mechanical Engineering Department is proposing one solution that supports specific criteria. This team is competing against another IED team for the best hammock park hanger design.

F06The Accessible Picnic Table for Open Arms CareStephen Burton, Grant Gronemeier, Lexi Johnson, Andrew MaysOpen Arms Care Day (OAC) Program Service in Ooltewah, TN currently serves 71 individuals with developmental disabilities. Many of the clients use wheelchairs as their main source of mobility. Being outdoors is a challenge for people who use wheelchairs. Sitting at a table in general is exceptionally challenging, especially a picnic table because the bench seating does not allow a person in a wheelchair to pull up to the table. In addition, the height of a traditional picnic table is not at an appropriate height for use by those in wheelchairs. The student team developed a wheelchair accessible picnic table for the OAC day program to enable the program’s clients can enjoy lunch and outdoor activities during nice weather.

F07Adaptation to Help Create ArtJames Jennings, Guido Marsile, Caleb Stevin, Sky WilliamsA University of Tennessee at Chattanooga (UTC) art student has poor fine motor skills and gripping her drawing pencils, brushes, and small objects is sometimes difficult. Specifically, gripping an art tool for a period of time causes pain in her wrist. The UTC Disability Resource Center (DRC) has tried to accommodate the student, but does not have any specific technology that can assist her. This UTC Mechanical Engineering Freshman Introduction to Engineering Design (IED) team is proposing a solution to help this art student be more comfortable when participating in art creation when using an art notebook or an easel.

F08Horseback Sensory TrailCole Antalek, Palmer Gray, Jordan Kent, Jake Phillips, Ethan ShotwellReinbow Riders, a program at the Tri-State Therapeutic Riding Center (TSTRC), is a therapeutic riding program that teaches individuals with disabilities how to ride. The program follows PATH International standards and practices hippotherapy - horses as therapy. The program works on balance, core muscles, following directions, dexterity, and so forth. The program is volunteer-based and runs after school and on weekends. The student team developed horseback accessible sensory activities for


children to see, hear, touch, and engage with along a trail outside of the main rink, assisting children with providing opportunities to practice balance and use their core muscles.

F09The Karate AssistantAli Aldrwish, Zuhair Alelq, Grey Drewery, Amanda George, Kenneth PruettDanny (not his real name) is an 11 year old child with spina bifida who enjoys karate and participates in classes and competitions. He can walk with forearm crutches but does not use them for karate because his hands need to be free. Danny has used his wheelchair for class and competition but this is inadequate. Ideally, he needs a freestanding device that provides support so he can be held in a standing position for kicks and have his hands free for punches. The UTC Mechanical Engineering Freshman Introduction to Engineering Design (IED) student team is proposing the Karate Assistant as a solution to help Danny participate in the karate activities he loves.

F10Sixth Sense Art TableJamie Bowers, Morgan Young, Tyler Nichols, Mario ManzoThe goal of the Sixth Sense Art (SSA) Table is to provide sensory stimulation for children with underdeveloped fine-motor skills while also giving children an artistic outlet for self-expression. The client, Danielle Bekeza, teaches children in grades kindergarten through third at Spring Creek Elementary. Many of these children have unique disabilities. The student team developed a table designed for students in wheelchairs to participate in art activities.


G01Smart Meter and Privacy: Preventing Occupancy DetectionJustin K Joshuva, Jonathan Land, Steven Hullender, Li YangIoT Devices like fitness trackers, smart watches, and smart meters make our lives easier, but they also are prone to security threats such as loss of privacy. These connected devices typically keep track of personal data including movements, locations and energy uses. The research is finding ways to mask and/or suppress the data or to group data to a cluster of non-recognizing patterns. By masking or groupig the data, the patterns are disrupted to prevent the detection of contents or called occupancy. Since the occupancy detection must be performed by statistical analysis, by disrupting the patterns, the statistical analysis would not render desired results.

G02Understanding Biological Networks in Framework of Phenotype and Gene CharacteristicsHaobo Guo and Hong QinThe protein-protein interaction (PPI) network BioGrid and the genetkic interaction network (GIN), CellMap of the budding yeast, Saccharomyces cerevisiae, have been quantified by the replicative lifespans (RLSs) of the single-gene deletion mutations. In both networks, the essential-

GRADUATE RESEARCHto-nonessential interactions are significantly reduced compared to random permutations. The PPI network was further represented in framework of protein length and/or intrinsic disorder content, highlighting the importance of protein disorder in wiring the vast amount of PPI interactions in cells. We present a powerful tool in understanding the architectures and stabilities of the biological networks, and provides potential directions for their maintenance and improvements.

G03Renovation Costing with Building Information ModelingRaghda Mohamed, Endong WangBuilding Information Modeling (BIM) has been increasingly employed in the U.S. building sector for various analyses since it can generate the required data associated with physical and functional characteristics necessary for the majority of parametric analysis. This study explores the opportunity of BIM in cost analysis for building renovation. By using 3D modeling, this project applies BIM to a campus building to develop a building renovation cost estimation process. It uses BIM as a platform to compare different renovation solutions and choose the best one base on life cycle cost. This study shows the benefits of using BIM for building renovation cost estimation process.


G04Towards a Smart, Dynamic, and Adaptable Network Design Using Virtual Slicing Over Software-Defined NetworkSteven Schmitt, Farah Kandah, Dylan Brownell, Peyton BallThe importance of reliable and adaptable networks has become increasingly relevant with the escalation of connectivity in our lives. The growth of streaming of entertainment and development of always online software have created an environment of large data flows that need to be handled efficiently. Historically this problem has been solved with hardware-based load balancers. Although these hardware-based load balancers provide a solution, they often times are expensive and lack flexibility and scalability. With the use of Software-Defined Networking (SDN), a more dynamic solution can be created to meet network load balancing needs

G05Tor’s Anonymizing Network: Uses, Misuses, and Routing TechniqueJonathan Land, Justin Joshuva, Li YangTor utilizes a unique routing technique that sets it apart from normal network routing. Even though Tor and onion routing have been misused by some, this technology has also been used, and was intended to be used, for good. The project’s objectives are to identify the proper uses and misuses of Tor, and to explain some of the characteristics of Tor’s routing technique, when compared to normal network routing techniques.

G06Develop a Family Tree Algorithm to Estimate Yeast Replicative Lifespan from Time-Lapsed Microfluidic ImagesMehran Ghafari, Hong QinThe goal of the research is to develop a family tree algorithm to estimate yeast replicative lifespan from time-lapsed microfluidic images. High-throughput microfluidics based assay of yeast replicative aging can significantly increase the speed and quality of yeast lifespan measurements. However, the major challenge is to efficiently convert large volumes of time-lapsed images into quantitative measurements of yeast cell lifespan. We address this challenge by prototyping an algorithm using a Bayesian approach that can evaluate cell division events through a family tree of cells. This generic method has the potential to not only accelerate the efficiency but also expand the range of quantitative measurement of yeast replicative aging experiments.

G07Software-Defined Networking Control Plane Challenges and Countermeasures: A SurveyMaxwell Omwenga, Farah KandahThe importance of the control plane in software defined networking (SDN) cannot be underestimated in this era of emerging technologies, such as Internet of Things, cyber security, smart cities/grid/health, 5G LTE, high performance


computing, deep learning, and quantum computing, just to mention a few. The quest for network connectivity that is robust, secure, agile and scalable is paramount, and SDN architecture provides a solution that meets the needs through what is called the SDN control plane. SDN comes with programmability, low operating costs, cloud abstraction and granular security. We are categorizing SDN control plane issues into four categories: namely, fault management, scalability, network updates and security. We present various challenges facing them and propose solutions and countermeasures. Some of the issues include but not limited to fault tolerance, controller scalability, forwarding black hole, network policy violation, distributed denial of service attack and Trojan based attacks.

G08Performance Analysis of a UAV Target Tracking System Using Different Coordinate Representations Zachary Ruble, Daniel PackIn this work, we perform analysis of an unmanned aerial vehicle (UAV) tracking a mobile ground target. Based on sensor availability, multiple coordinate frames can be used to derive the system dynamics. We introduce and compare the performance of controller/estimator pairs in four different coordinate frames: a spherical coordinate frame, an inertial coordinate frame, a polar coordinate frame, and a decoupled coordinate frame. Each controller determines desired pitch and yaw angles of the UAV based on the system dynamics found for each coordinate frame, and an extended Kalman filter (EKF) is used to estimate the

coordinate states. The performance of each controller and estimator pair in tracking a ground target is evaluated through simulations with varying target and UAV speeds.

G09Comparative Analysis Between MERRA and Updated MEPDG Climate Database in the State of TennesseeAbubakr Ziedan, Mbaki OnyangoThe Mechanistic-Empirical Pavement Design Guide (MEPDG) addresses climate effects on pavement design in a comprehensive way, which allows for investigating the effect of climate inputs on pavement performance. However, it requires detailed climate inputs, which might not be available for most of the state DOT. The updated “AASHTOWare” climate database encompasses twelve stations in the state of Tennessee, which might not well represent all climatic regions in the state of Tennessee. This study compares and evaluates the performance of pavements in Tennessee using Modern-Era Retrospective Analysis for Research and Applications (MERRA) and the updated AASHTOWare databases as a source of MEPDG climate data inputs. A comparative analysis between these two climate data sources using eight LTPP sites in Tennessee was conducted. It was found that using MERRA as a climate data source for the state of Tennessee will offer better geographic coverage and, therefore, more precise distress predictions are expected.


G10Synthesis and Transport of Nanoparticle DrugsSoubantika Palchoudhury, Yaqeen Al Hussain, Abdollah ArabshahiNanodrugs are highly promising candidates for future medical solutions as they can be specifically targeted and can provide diagnostic capability. Understanding the accumulation and transport behavior of nanodrugs in vivo is still in its developmental stage. In this project, a new Pt-iron oxide nanodrug was synthesized in our lab. Subsequently, an experimental approach was developed to investigate the flow of this nanodrug through customized channels. The experimental flow pattern showed excellent correlation with a new computational fluid dynamic model developed in collaboration with the SimCenter to predict transport of these nanodrugs. This method will be useful in drug delivery applications.

G11Connectivity Control for a Network of Unmanned SystemsJames TrimbleConnectivity is a metric for the robustness of a network. For unmanned systems, various real-time requirements necessitate different levels of connectivity throughout a mission. The goal of this research is to provide a distributed method of controlling connectivity for a network of multiple unmanned systems.

G12Malaria ProjectDaniel Pack, Zachary Ruble, James TrimbleThe goal of this project is to use multiple cooperative unmanned aerial vehicles (UAV) along with a ground entomologist team to search, detect and treat mosquito larvae sites. The DJI S1000 octocopter is used as the UAV platform, controlled by a Pixhawk Flight controller. Additional components, such as a telemetry radio, a Global Positioning System, voltage sensor and regulator, and a camera system make up the onboard system for each UAV. UAVs are used to map areas of interest, detect potential mosquito breeding sites in working with the ground team, test for mosquito larvae by sampling the water, and dispense larvicide into verified larvae locations.

G13Development of a Simple Chrome ExtensionEisa Mohamed, Li YangWeb browsers, used by billions of people around the globe, help users to surf different web pages quickly and securely using security features associated with these web browsers. However, some users may like to customize or add some functionality on top of what is provided by web browsers. This is done through browser extensions. The objective of the project is for students to understand how browser extensions work, their architecture, development environment, security risks associated with installing malicious extensions, and how to develop a basic chrome extension while maintaining the minimum-security standards.

G14Occurrence and Fate of Nanomaterial in Surface Water EnvironmentBreana Harvell, Avery CowanManufactured nanomaterial (NM) are increasing globally in terms of production and use. NM have diverse applications in the modern world and can be found in many electronics, plastics, cosmetics, and other household items, as well as being used in industrial production for vehicles and textiles. The medical field has also found many uses for these materials. Their increased production and use also comes with increased potential for their contamination in environment, especially their entry into surface water and air systems. There is a wide variety of NMs, each with unique physical and chemical properties and hence their transport and fate mechanism in natural environment. However, since the NMs use is consider still as very early stage, there is no significant information of their occurrence in surface water systems. We focus on identifying common nanomaterial with the highest contamination potential in surface water systems, their physical and chemical properties, along with their prevalence in non-point source runoff. We present our research findings of NM fate and transport behavior that could provide insight in designing controls for their treatment.

G15Developing Voltage Stability Indicators for Power SystemsSiddig MohammedIn this research work, we define a new stability index called the “P-Index,” published in an IEEE Transactions on Power Systems (June 2017) paper. This is a novel concept developed entirely at UTC. This stability index outperformed the methods currently used for flagging voltage instability such as the L-index and the CSPC method. We are currently looking into expanding the P-Index principle for predicting the Voltage Collapse point for different loading categories such as motor loading and voltage sensitive loads. We are also exploring second derivative calculations for higher accuracy.

G16Building and Testing an Inexpensive 3D Printer for ENME5160Michael Harrington, Alvin Thompkins, Eric Williams, and Will SuttonMechatronics (ENME5160) at UTC is an introductory course that integrates applied concepts of mechanical and electrical systems. One example of a mechatronic application is three dimensional printing (3D) of solids. All such printers were once quite expensive and unreliable. Recently, cheaper hobby-based from kits 3D printers became available. But as recently as last year, available models were not really suitable except for truly gifted experts. As a project in Mechatronics, we built and test a


newer kit based (RepRap) 3D printer. We document the build and test of such a printer. Our experience showed that building such a printer is still not trivial, but the final printer has proved to be reasonable to operate. We also discuss the open software used to process 3D models, importing models from an available 3D drawing package, and using MS-Kinect to scan in 3D.

G17Moving from Fortran Simulations to Python using Raspberry PIWill SuttonThe inexpensive Raspberry Pi was intended to teach grade school children computer science, but has since become main-stream. Models have a Debian Linux OS, and include a web browser, the Python computer language, an integrated math solver, and hardware connections (internet, USB, HDMI, GPIB data , and camera). Gfortan, Matplotlib, and SciPy (Scientific Python) were added to the Pi 3 used here. Last Fall, I taught graduate Automotive Simulations, partly based on the Pi 3. I had significant original work already programmed in Fortran-77 (very fast on Pi 3), which was once ubiquitous to Engineers and Scientists. Current students rarely know Fortran, the focus moved quickly to using Python, Mathematica, and Excel-like spreadsheets to look at computer-based solutions that might be applied to automotive systems. The SciPy libraries added to Python 3 are very well suited for technical calculations. The learning process and comparison for a research code in both languages are presented.

G18Protection of Communication and Access to Undergraduate DataHector Suarez, Li YangMapping, assessing and monitoring underground infrastructure, i.e. the water, sewer, gas, electricity and other supply lines that are vital the modern society, are excellent applications for smart cities technologies. Aggregating ground penetration radar images is one method available for locating underground utilities, but can be challenging in urban environments due to the congestion of the underground infrastructure We developed a system that maps underground infrastructure via a ground penetration radar, for improving the quality of services of underground infrastructure. The radar images are securely sent to a remote server where city planners and infrastructure managers can visually assess the underground infrastructure.

G19SCRaaPS: X.509 Certificate Revocation using the Blockchain-based Scrybe Secure Provenance SystemSai Medury, Anthony Skjellum, Richard Brooks, Lu YuInternet economy, notably secure web servers. The original revocation method specified in the X.509 standard to distribute certificate revocation lists (CRLs) is both old and untrustworthy. CRLs are susceptible to attacks such as Man-in the-Middle and Denial of Service. The newer Online Certificate Status Protocol (OCSP) and OCSP-stapling


approaches have well-known drawbacks as well. The primary contribution of this work is Secure Revocation as a Peer Service (SCRaaPS). SCRaaPS is an alternative, reliable way to support X.509 certificate revocation accomplished using the Scrybe secure provenance system. The blockchain support of Scrybe enables the creation of a durable, reliable revocation service that can withstand Denial-of-Service attacks that ensures non-repudiation of certificates revoked. We provide cross-CArevocation information and we address the additional problem of intermediate-certificate revocation with the knock-on effects on certificates derived thereof. A Bloom filter provides quick, communication-free testing by servers and browsers against our current revocation list (with no false negatives). A further contribution of this work is that the revocation service can fit in as a drop-in replacement for OCSPstapling with superior performance and coverage both for servers and browsers. Potential revocation indicated by our Bloom filter is backed up by rigorous service query to eliminate false positives. Bloom filter parameters are also stored in our blockchain to provide open access to this algorithmic option for detection. As further motivation for our approach, a case study involving a recent, 23,000-certificate revocation is included.

G20Girls to Engineers Network (GEN)Hana KarrarEngineering Management, Engineering, and Computer Science Departments at the University of Tennessee at Chattanooga (UTC), in collaboration with the Chattanooga Girls Leadership Academy (CGLA), has designed UTC Girls

to Engineers Network (GEN), a project-based learning (PBL) program to encourage middle school girls in engineering.

G21The Community Design StudioNeslihan Alp, Dana Moody, Raghda Mohamed, Hana Karrar, Sarah Hamilton Hathcock, Alexandra HuntWe explore ways an interdisciplinary design studio can bring visibility to a declining neighborhood while helping low income residents improve their living conditions.

G22Infrastructural Crack Detection & Localization Using Deep Convolutional Neural Network, Infrared Thermography, and UAVM.A. Qurishee, B.A. Atolagbe, W. Wu, J. Owino, I. Fomunung, M. OnyangoManual inspections of infrastructures such as highway bridge, pavement and dam are time consuming, life threatening occasionally and costly. An automated computerized system can reduce time, faulty inspection, and cost of inspection. In this project, we developed a computer model using deep learning Convolution Neural Network (CNN), which can be used to automatically detect cracks, crack types, crack lengths, and crack locations in the structure. The ultimate goal of this research is to allow application of state-of-the-art deep neural network and Unmanned Aerial Vehicle (UAV) technologies for


infrastructural crack inspection. For the implementation of deep learning in intelligent infrastructure, we study the recognition and classification of crack of UTC campus garage concrete ceiling slab. A total 2086 images of 5,312 × 2988-pixel resolutions of crack and non-crack were taken from UTC Old Library parking garage ceiling using Phantom 4 pro drone and handheld mobile phone. These images are used for training and testing the deep neural network. The proposed CNN model shows better performance in realistic situations compared with traditional image processing techniques such as Sobel, Canny, Robert, Prewitt, Laplacian of Gaussian etc.

G23Radiation Effects in Silicon PhotonicsRyan Boggs, Daniel LovelessRecent developments in nanostructures, metamaterials, and integrated silicon technologies have enabled new functionality in highly integrated photonic integrated circuits (PICs), where optics and waveguides are meshed directly with semiconductor material on a single chip. As such, PICs are considered an emerging technology for high-speed, reliable communication, including the micro scale (i.e. chip to chip communication through I/O) and the macro scale (i.e. satellite bussing). Some of the driving forces behind the interest include: the potential for new capabilities such as quantum computing, data transfer rates in the Tb/s range, and the potential to overcome the scaling limits of metal interconnect technology. However, little is known about the resiliency in hostile (radiation) environments. This project aims to develop and incorporate radiation models into photonic component simulations and

compare the results with existing research and those obtained experimentally. The simulation results will be used to inform development of a PIC technology characterization vehicle (TCV), and to inform early radiation testing of discrete PIC components.

G24Assessing the Impacts of Workforce Participation Rates in Telecommuting Programs on VMT And Emission Reductions in a Mid-size CityAbubakr Ziedan, Ignatius FomunungManaging congestion is one of the biggest challenges facing any city or metropolitan area irrespective of size. Several studies have demonstrated the advantages of telecommuting as a travel demand management (TDM) tool, including a reduction in Vehicle Miles Traveled (VMT), reduction in harmful emissions, enhanced air quality and reduction in traffic accidents. However, these studies were conducted at the national level or in large cities, which may not be predictive of the impact of telecommuting on mid-sized cities with a smaller workforce. This study assesses the impacts of employee participation rates in telecommuting programs on VMT and emission reductions in a mid-size city. The analysis revealed that telecommuting has major environmental impacts on mid-sized cities and can be an effective Congestion Mitigation and Air Quality (CMAQ) tool. It was also found that high percentages of engagement in telecommuting are needed to achieve considerable VMT reductions.


G25Residential Construction Company Startup: A Customer Centric ApproachTimothy S. McGee, Alexandr M. SokolovThe purpose of this project is to identify the requirements associated with creating a successful business model based on professionalism, honesty/integrity, and customer satisfaction. Through research, a void in the marketplace for a residential construction startup that caters to senior citizens is identified. This project takes a holistic approach in outlining the business model and the challenges associated with emerging into a new business venture. Competitive advantage, marketplace barriers, customer expectations, company vulnerabilities, and sustainability were topics of research in determining feasibility. This project concludes with recommendations for future studies that further promote market penetration for the proposed company.

G26Energy Anomaly Detection with Machine LearningKeith Hollingsworth, Jin Cho, Mina SartipiMonitoring energy consumption data is essential to the everyday workings of power companies; a single uncaught incident outside the standards of normal use can result in financial loss. To minimize the repercussions of an uncaught error, the utilization of forecasting and machine learning can significantly improve the detection of such anomalies in day-to-day operations. This study covers power anomaly detection on energy delivery systems with the use of deep learning algorithms that have the capability of removing seasonality and trend from data, yielding residual values that are applied in a comparison to values generated from predictive analysis using recurrent neural networks (RNN).


G27A/C Load Forecasting Using Deep LearningJin Cho, Zhen Hu, and Mina SartipiIn the United States, the residential and commercial sectors are responsible for almost half of total energy consumed. Additionally, air conditioning accounts for the majority of energy consumed in residential buildings. In order to reduce the energy consumption of the building, we identify the behavior of A/C energy consumption by estimating the future A/C load. In this paper, we will explore deep learning-based algorithms to estimate A/C energy consumption using the smart meter data and outdoor temperature data. We will utilize data provided by Pecan Street to validate the performance of proposed task. Our results will demonstrate the strength of deep learning algorithms in solving load forecasting problems, and help in further investigations.

G28All-in-One Urban Mobility MappingRebekah Thompson, Jose Stovall, Daniel Velasquez, and Mina SartipiThe AIO Locator project will present a mobile application that combines visual data extracted from cameras on roadway infrastructure with a user’s coordinates via a GPS-enabled device to create a visual representation of the driving or walking environment surrounding the application user. By merging the concepts of computer vision, object detection, and mono-vision image depth calculation, this application is able to gather absolute Global Positioning System (GPS) coordinates from a user’s mobile device and combine them with relative GPS coordinates determined by the infrastructure cameras and algorithm. The joined data is then used by an iOS mobile application to display a map to the user showing the location of other entities such as vehicles, pedestrians, and obstacles, creating a real-time visual representation of the surrounding area. Furthermore, a feature was implemented to display optional routing by using the results of a traffic scenario that was analyzed by rerouting algorithms in a simulated environment. By displaying where proximal entities are concentrated and showing recommended optional routes, users can be more informed and aware when making traffic decisions helping to ensure a higher level of overall safety on our roadways.


S01USST Transformer Replacement Sequoyah Nuclear PlantRobert Smith, Devin Baker, Ethan Hunter, Ty TuckerAn existing transformer (USST 2A) is being removed and a new larger transformer is being installed. Analysis of the existing foundation is required to determine if the existing foundation can be re-used, or if a new foundation is required. We show our findings in this senior project. Existing shallow fire protection water supply lines embedded in the existing foundation must remain active. Embedded miscellaneous steel protection must also be incorporated in the new foundation as this is essential equipment and must meet ASCE 7 Category I standards.

S02Lot #10 Improvements - Parking GarageBraden Wells, Janson Roberson, Savannah Wexler, Wesley BurchfieldIn this project, the group was presented with the task of improving parking lot #10 which is located in the center of The University of Tennessee at Chattanooga’s campus. The group agreed that a parking garage in the lower portion of lot #10 would be the best option to deal with a growing parking problem. Many complications had to be avoided including pedestrian traffic, drainage, and entrance/ exit location. Aside from the technicalities for this project, the team decided to make this parking garage very student

friendly by adding a bicycle storage rack and a P.O.D. market. In conclusion, the team has a good looking, student friendly parking garage that increases the number of centrally located parking spots.

S03Facial Recognition Auto AttendanceKyle Gould, Eric Camp, James Lee, Zach PrattIn colleges today there never seems to be enough time in class spent learning. This is exacerbated by the fact of taking attendance on a daily basis. Our overall goal is to reduce the time for attendance and give teachers more time to cover the course material. Current methods are time consuming and prone to being falsified. To solve this issue, we’ve decided to use Microsoft’s Azure facial recognition and detection software and develop a graphical interface that can automate this process by analyzing uploaded pictures of individuals or groups of students for the teachers. This software will utilize pictures taken to recognize that students are present for the class period. This software will even learn from previous pictures based on how each student’s appearance changes.

S04The Chesapeake Bay Bridge ProjectBradley Polanco, Chad Littleton and Brendon KoonThe Chesapeake Bay Bridge Tunnel system is one of three in the United States that spans more than 20 miles, the system connects Virginia’s Eastern Shore and South


SENIOR DESIGN

Hampton Roads, Virginia. The part of tunnel between the Thimble Shoals and Chesapeake Bay Channels is a two lanes in each direction. Recently, permission has been granted to build a bridge parallel to the Chesapeake Channel Tunnel. This design project consists in the preliminary design of a bridge which would meet the requirements of traffic, weather and height for shipping.

S05Lie to Me: The App Jeremy Roland, Stephen Rau, Brad Britton, Donna Nguyen, Steven HullanderEveryone lies at some point. It is simply part of human nature. To detect a lie, one needs to understand the physiological responses, verbal language, and physical language of the person being questioned. Moreover, the questioner should have strong perceptive, communicative, and personal skills. Trying to master all methods of lie detecting is a daunting task for anyone. We have created an application for training people in becoming better at detecting lies. In short, the app takes in user input and returns a percentage opinion on whether the subject is lying or not. Moreover, our app stores subject profiles and test results on local device storage, contains a manual on lying ‘tells’, and provides the user with quizzes to test his/her knowledge on lying. The app is meant to act as training wheels for a user to train in detecting lies, in order to accurately detect a lie.

S06Traffic SimulatorDaniel Storey, Robert Parmentier, Brandon Robertson, Morgan Sanborn, Evan GraysonTraffic has increased in the mythical town of Wills Valley, Alabama. This uptick has started to cause a lot of traffic problems such as congested blocks and deadlocks. Examining open source software, a number of programs that are very similar to the application we are trying to build were found. After analyzing those programs, we have created an application that can be configured to model the intersections of any city or town. Traffic engineers will be able to simulate traffic conditions, run scenarios that include light timing changes, and changing two-way streets to one-way streets. This computer application demonstrates how the flow of traffic can be improved and solutions can be created by mapping out different traffic scenarios on a grid that replicates the town being observed before implementing any changes.

S07Using Smart Phones and Watches to Detect Falls and Get Help for the ElderlyAustin O’Byrne, Ben Meyer, Alay Patel, Derek Snyder, Claire L. McCulloughThe purpose of this research is to develop an application which can accurately detect and assess when a user falls, using machine learning techniques. When such an event occurs, a designated contact or caregiver will be notified and can provide aid. While there have been numerous


journal articles written on the detection of falls, the main focus of the research is on application and not theoretical development--i.e., a product which detects falls, using the sensors such as accelerometer, gyroscope and GPS on mobile devices that many individuals already own, such as accelerometers and gyroscopes located on the wrist (as in a smartwatch) or in the pocket (as in a smartphone). Research by the Center for Disease Control (CDC) indicates that faster Emergency Medical Service (EMS) response could both reduce the economic cost of falls and boost the emotional wellbeing of fall victims and their families. It is believed that by first contacting a designated caregiver (and thereby adding a ‘human in the loop’) the chances of accurate detection and appropriate response can be vastly improved, instead of depending solely on an automated process and possibly exposing the user to inconvenience or danger from algorithmic false positives. If the application running on the cell phone detects a fall, the application will make a call to a predetermined telephone number, and send a text message displaying the location of the user, via a google maps hyperlink.

S08Let’s Synthesize: Musical ProjectSharhea Bell, Chelsea Merriman, Matthew Neal, Claire L. McCulloughA music sequencer, also known as a step sequencer, is a digital electronic device or application software that can record, save, edit, and playback music. A sequencer can also be described as a “programmable electronic device for storing sequences of musical notes, chords, or rhythms and transmitting them when required to an electronic musical

instrument.” Sequencers come in all shapes and sizes, with different voltage outputs and control methods. These devices are able to handle “note and performance information in several forms, typically Controlled Voltages, gates, MIDI, or Open Sound Controls (OSC), and possibly audio and automation data for Digital Audio Workstations (DAW) and plugins.” We designed and developed a sequencer with an 8-step musical sequence. The 8-steps of the sequencer consist of voltages and frequencies that controls the sound’s pitch and amplitude. The octaves per voltage of the sequencer should provide the ability to quantize voltage to a specific pitch producing the correct scale. Generating input and output voltages for a functioning sequencer is critical to the success of the project. The overall goal and criteria for the project is the following: design an 8 step sequencer, portable capability, include a quantizer to set the pitches of the sequencer, a tempo knob that sets how quickly the beat plays, an internal clock, and have the ability to connect to a synthesizer that meets the Eurorack Standard.

S09Industrial Wastewater Treatment Design via an Aerobic Sludge ProcessAustin Boswell, Sara Lockhart, Christopher PurvisThis project was carried out as part of the requirements for ENCH 4300, Chemical System Design. Our objective was to produce a feasible, preliminary design for an industrial wastewater treatment facility using an activated sludge process, with a two-year payback date. The streams in question were a 20% ammonium chloride solution, and wastewater from the production of a proprietary anionic


surfactant used in the personal care industry. Our end goal was to deliver a design that reduced the biochemical oxygen demand (BOD) and nitrogen content of the waste streams to allowable concentrations for discharge to publicly owned treatment works (POTW).

S10Design of a Scrubber System for Removal of Hydrochloric Acid from Tanker Off-GasesDagan Burnett, Jackson Champion, Elizabeth Davis, Hunter EberleThis project was carried out as part of the requirements for ENCH 4300, Chemical System Design. Our objective was to design a system to manage the hydrochloric acid present in the off-gases of a tanker unloading system. The tankers in question were used to unload hydrochloric acid (36% HCl by weight), and had a nominal capacity of 4,000 gallons. The acid was off-loaded by applying air pressure to each tanker and forcing the liquid into a storage tank of nominal 15,000-gallon capacity. Our end goal is to provide a feasible, preliminary design complete with an equipment list and design basis, cost estimate, plot plan, and project schedule.

S11Design of a Heat Exchanger for Temperature Control of a Batch ReactorJustin Miller, Pratiksha Patel, Nick Peck, Jessica PhillipsThis project was carried out as part of the requirements for ENCH 4300, Chemical System Design. Our objective was to

design a heat exchanger to remove the heat generated during a batch reaction in order to maintain the reactor at a constant temperature. The reaction in question was the production of lanthanum chloride by dissolving lanthanum oxide in hydrochloric acid. Our end goal is to provide a feasible, preliminary design complete with an equipment list and design basis, cost estimate, preliminary piping and instrumentation diagram, and project schedule.

S12Design of a Treatment Process for a Latex-based Wastewater StreamDaniel Hill, PaTrisha Jacobs, Tyler Marlow, Lucas PleskyThis project was carried out as part of the requirements for ENCH 4300, Chemical System Design. Our objective was to design a system to manage the latex-based wastewater generated during railcar cleaning. Previously, this wastewater was captured in a storage unit and processed off-site for a fee. Approximately 300 gallons of wastewater was generated per railcar, and annually there were 200 railcars cleaned. Our end goal was to provide a feasible, preliminary design complete with an equipment list and design basis, cost estimate, process flow diagram and plot plan.

S13WFFI Tracker Database ProjectJames Hare, Richard Kimsey, Daniel Velasquez, Javier MartinezAs part of our Undergraduate Senior Capstone Design Project, we have improved a Tracker Database System used


by Woodbridge Foam Fabricating Inc. (WFFI). The current tracker database consists of 40 tables and 60 reports which are accessed daily by floor managers and employees to assist in the documentation of product quality at various stages in the manufacturing process. WFFI management decided that an update to Microsoft Access 2016 was beneficial for ease of use, to facilitate data transactions and to improve accountability. We have added features to the existing database, based on prioritized business requirements, and in the process gained valuable experience in the Software Development Life Cycle.

S14Design of an Extractive Distillation System for Butadiene RecoveryHamad Alresheedi, Mitchell Rayl, Laura Ryan, Cooper ThomeThis project was carried out as part of the requirements for ENCH 4300, Chemical System Design. Our objective was to design a system to increase the purity and amount of recycled butadiene recovered from a chemical process that used butadiene as a reactant. Previously, butadiene was recovered via separation from other unwanted by-products using a vent drum. This process was costly and inefficient, as a substantial amount of the recycled butadiene was being lost and sent to a thermal oxidizer with the by-products. Our end goal was to provide a feasible, preliminary design complete with an equipment list and design basis, cost estimate, process flow diagram, and hazard analysis.

S15Design of a Batch Process for Production of an Alkyl Glycidyl EtherAbdul Alajmi, Desirae Baldivid, Drew Birdwell, Jeremy RodenThis project was carried out as part of the requirements for ENCH 4300, Chemical System Design. Our objective was to design a batch chemical process for the production of n-octyl glycidyl ether, a chemical intermediate used in the manufacture of a variety of products. In particular, we were tasked with evaluating the economics of constructing a production unit to manufacture 10 million pounds per year of n-octyl glycidyl ether beginning in 2020. Our end goal was to provide a feasible, preliminary design complete with a process flow diagram, material and energy balances, an equipment list and design basis, and a cost estimate.

S16”Freedom Brewing”: Preliminary Design of a MicrobreweryCody Flowers, Alicia Gillis, Kathleen Garrabrant, Ryan HastingsThis project was carried out as part of the requirements for ENCH 4300, Chemical System Design. Our objective was to design a brewery with a production size of less than 15,000 barrels (465,000 gal) of beer per year. We developed a design for a full-scale microbrewery that can produce up to 7,000 barrels (217,000 gal) of up to 3 different types of beer per year. The production takes advantage of batch scheduling with efficient use of downtime management in


order to work as efficiently as possible with maximum production potential. Our end goal was to provide a feasible, preliminary design complete with a process flow diagram and batch scheduling chart, an equipment list and design basis, and a cost estimate.

S17CHI Memorial Emergency Department StaffingSeth Bishop, Kayla CalfeePatients arrive to the Emergency Department (ED) of Memorial Hospital of Chattanooga (CHI) in varying day-to-day patterns. This presents a challenge in adequately staffing the ED while maintaining budget and productivity standards. If nurses are not available, patients may wait, which is a safety risk and patient dissatisfier. If nurses are fully staffed for the entire ED, they may be underutilized and the ED will not meet their productivity. Using industrial engineering principles, a team of BSE: Industrial Engineering Capstone students propose a daily nursing staff schedule for the main campus of CHI in Chattanooga to improve patient visit times while maintaining budget and productivity standards.

S18Retrofitting Urban Streets with Runoff ControlsBrad Campbell, Grant Walters, Haley Stewart, Mike FletcherIn this project we plan to retrofit runoff controls for the Hamilton Place Mall Parking lot. Historically, this parking lot

causes runoff damage and has a low rainwater infiltration rate. By designing storm water runoff control for each catch basin we can utilize permeable pavers, bio-swales, rain gardens, and other low impact developments. These technologies will increase the stay on water volume for the mall. Increased stay on volume will reduce storm water fees and flooding of nearby Friar’s Branch creek. Another constraint is minimizing parking capacity loss, which can in return reduce store parking density. With the advancement in green technology and low impact design, our group should be able to reduce runoff and maintain parking capacity for the mall.

S19Seismic Monitoring of Small-Scale StructuresWilliam Brown, Gheorghe Meyer, Logan Kornblum, Nathan Scogginshe purpose of this interdisciplinary design project is to The purpose of this interdisciplinary design project is to compare experimental and analytical techniques for the purpose of studying the health monitoring system of a small-scale structure. To test this, we plan to build a three story building with beams and columns. Wireless acceleration sensors and displacement sensors will be attached at various locations on the building. A shaking table will be used to model the earthquake load. Two different experiments will be conducted. One experiment will be conducted with the beams and columns in good condition. The other experiment will introduce imperfections in the beams and columns. A finite element model will be constructed to match the geometry, physical


properties and boundary conditions of the building structure. The two different experiments will be compared to the finite element model. The acceleration response and displacement data will be collected by the wireless sensors to explore and identify the damage zones in a building. Long term goal of this research can be introducing artificial intelligence into automation of structural health monitoring.

S20Mocs Arcade Retro Video GameMatthew Marshall, Grace McPherson, Casey Stinnett, Jose Stovall, Peter WayThe Mocs Arcade is an arcade machine created via The Mocs Arcade is an arcade machine created via collaboration between the Computer Science and Computer Engineering programs. It has been a creative way for students to showcase their technical abilities by applying principles learned in class; they create polished video game projects that demonstrate skills applicable to the real world. Our team’s objective was to reinvent a classic arcade game. Twotris, short for “Two-player Tetris”, leverages multiplayer dynamics. Twotris aims to shatter the classic image of Tetris, take these shards, and put them together in a whole new way. Jam-packed with customizable features and up to three different game modes that Alexey Pajitnov never wrote, Twotris will prove to be a game that is impossible to put down.

S21Woodbridge Monitor HubMatthew Residori, Jennifer Rutherford, Jordan Schaff, Brennan HuberA digital signage system used for information dissemination among employees by the Woodbridge Group, a global manufacturing company, is non-scalable and relies on overly complex user interactions. This team was commissioned to provide a cloud based, globally scalable central hub from which objects on a display screen may be stored, modified, and viewed. The system simplifies a user’s experience by accepting Microsoft Power Point files and converting each slide into an individual image to be displayed. The system was created using Google Cloud Platform to enable global scalability. This monitor hub reduces the reliance on complex user input and provides global scalability through the Google Cloud Platform.

S22Design of a Coal Combustion Residuals Removal ProcessCaleb Casey, Brianna Nelson, Jeremy TaylorThis project was carried out as part of the requirements for ENEV 4300, Environmental System Design. Our objective was to present potential options for disposal and beneficial reuse of coal combustion residuals (CCRs) contained in a surface impoundment. Cost efficiency as well as environmental mitigation were important factors in the design process. Our end goal was to inform the public about coal ash and its implications for the environment and public health.


S23The IEEE Robotics TeamWilliam Garner, Scott Rinehart, Nicolas Mateo, Libby Worley, Tony Ferguson, James Kyle HaleThe goal of the project is to not only create a working robot but to optimize it to get as many points as possible and ultimately place in the IEEE SouthEast robot competition. At the competition, the robot will receive an 8-bit binary code, of which the 3 least significant bits are the coordinates of locations to which robot must travel. In order for the robot to receive all points for this task, it must move to each destination in the correct order. At each destination, the robot also must perform a task. At the first destination, the robot must push a button to lower a ramp. The robot then moves down the ramp to the second destination, where it will move a pressure pad. From there, the robot will rotate a wheel to raise a flag and then pick up a “treasure chest,” then go back up the ramp to the final destination and push the button again to end the round. The picking up the treasure chest and rotating the wheel are not required but are needed in order for the team to receive all possible points.

S24Beethoven’s Fountain Greg Draeger, Braxton Towry, Eddie Bodnar, Andrew Lawson, and Edgar SindlerThe goal for this project is to provide an interactive water fountain display that allows the user to plug in a music device, and have the fountain “play” a unique display based on the song being played. Currently there are no water

fountains on the market that are in an affordable price range that will provide a visual display of music being played in real-time. One of the four main objectives is designing a frame that will house all the components and at the same time be aesthetically pleasing. It was decided to use a hexagonal jet layout that will also be mirrored by the steel frame. The second is writing a code that will decipher an audio input into a striking visual representation without much of a delay. The third objective is to design a water system using solenoid valves and pumps that will be noise-free and easy to maintain. The last challenge is attaching LEDs in a way that they would illuminate the water jets while at the same time making sure they are water-proof.

S25Implementing a Full Automation with Performance Improvement of a Tire Recycling Machine Jessica McCaw, Joshua Smith, Matthew Totton, Tejashkumar PatelThe objective of the project is to automate and implement safety features for the existing process created by Rubber Recovery Solution, LLC, to remove the tread from spent tires, leaving behind the steel belt. The modifications of the machine should be made such that it is replicable and able to operate in harsh commercial environments. The group has designed a convenient and ergonomically friendly way to control the machine after a tire has been loaded. The carcass will be easily removable. Structural modifications to the placement of the blade and its hydraulic cylinder are


recommended. The group plans on having a fully automated tire recycling machine, that is safe for both operator and bystanders.

S26Designing a Proposed 500-161 kV UTC Substation Bill McBryar, Josh White, Austin Babb, Matt Hudson, Stan BrownThe scope of this project is to design a 500/161 kV substation to meet the needs and design standards of a client company. It will be designed to transmit power between the existing Sequoyah and Watts Bar 500kV Transmission line to four new 161 kV transmission lines that feed new power delivery points. The client has provided a specification diagram and requested all designs to meet IEEE guidelines and specifications. The substation will consist of a 500kv switchyard, a 500-161kV transformer bank consisting of three single phase 500-161-13 kV transformers with a spare transformer with identical ratings and a 161 kV switchyard. The communications and protective system will also be provided.

S27Upgrading a Locomotive Telemetry Device (LTD)Jason Cobb, Russ Bazemore, Daniel Witt, Brandon WhitleyLocomotive Telemetry Device (LTD) Team was created to improve the prototyped LTD. The function of the LTD is to


store data captured from the CAB of the locomotive. The prototype currently consists of a Raspberry Pi and runs on Python code. It is spliced into the wiring between the CAB and the Diagnostic Display Panel (DID) of the locomotive. The LTD”™s purpose is to allow for automatic querying and storage of sensor data that would otherwise require manual cycling of the DID and the absence of a data storage medium. The improvements to the LTD include making the LTD manufactural and creating analytical software for the information collected by the LTD.

S28Designing a Flexible On-Board Electrical Vehicle ChargerClayton Raulston, Jonathon Rinkel, Robert Davies, Abdullah BahkaliThere are multiple ways to charge an electric vehicle (EV). However, the outputs of these sources are in either using an AC current or a DC current; both with varying voltages. Therefore, the on-board EV battery charging team decided to design an electrical vehicle charger that can accept any kind of input voltage source. It will utilize a DC/DC flyback converter to convert the DC current into a voltage necessary for the battery to charge, and an AC/DC converter to convert the AC current into a DC current. It is also necessary to design protection for the unit to prevent overheating.

S292018 Baja SAE Steering, Suspension, and Ergonomic DesignAlexandra Disterdick, Eric Endsley, Justin Harris, Nicolas Oberg, Trevor ElliottIn order to improve the overall steering on The University of Tennessee at Chattanooga’s SAE Baja vehicle, engineering analysis will be completed to develop a model for suspension and steering geometry. This model geometry will be used to manufacture new steering arms, tie rods, and potentially a new rack and pinion. These improvements will create a turning radius of 7-feet or less. Along with these accomplishments, an adjustable steering column will be implemented to fit the 95th percentile male and the 5th percentile female. Installing an adjustable steering column will allow the driver to adjust the wheel to his or her height specifications.

S30Thermal Optimization of 18650 Lithium Ion BatteriesAmeer Jibrin, Noland Smith, Tyler Evatt, Nicholas Hall, Trevor ElliottCoulometrics, a leading battery manufacturer in the Chattanooga area, is interested in altering current battery pack designs to optimize their performance. These packs normally contain a number of 18650 Lithium ion battery cells connected in series and/or parallel. This design project will utilize 18650 Lithium Ion battery cells. There are many aspects to look at to optimize these batteries but after

collaboration with Coulometrics, this design project will focus mainly on reducing the operating temperature of these batteries. To do this work, we will look at tab placements, geometries, materials, locations, and the thicknesses of coatings.

S31Ignition Coil Materials Separation DesignAbdulrahman Alqahtani, Kayla Calfee, Michael Garrison, Dustin Gray, Sarah Thomas, Trevor ElliottDenso Athens, an automotive manufacturer, has a recycling problem involving rejected parts from their ignition coil manufacturing line. The project mission is to separate the materials that make up the three different types of ignition coils produced for Honda, Toyota, and GM. To achieve this, the Denso Recycling team has decided to heat the ignition coils to 578 degrees, in order to melt the plastic, separating it from the copper. Our mission is to achieve 90% automation which allows Denso to be able to recycle the copper, and also to be able to dispose of the terminals and plastic in an easy and efficient way.

S32Flywheels Vehicular Coupling Design ProjectAli Alamri, Nasser Alharbi, Turki Alharthy, Brendon Baker, Brandon Clounch, Zachary Jenkins, Brittany Schidel, Trevor ElliottThis Project addresses the ever-rising problem of traffic in cities and polluting effects of mass transport. With the shift towards autonomous vehicles, the sensors and computing


power already installed in this new generation of cars can be utilized to form a coupling system between cars or pods for a better fuel efficiency, reduced accidents and more efficient use of the road system. The pods can be termed as Smart-Pods since they require no driver input at all, and instead use an array of on board sensors and GPS-system to orient themselves.

The new building will house all pediatric subspecialty physician clinics, but will have an entirely new workflow as compared to the current pediatrics clinics in the existing building. This project aims to study various scenarios for a new registration/check out process, to find an optimal solution. Lean Six sigma DMAIC is used as a road-map of the study.


S36Quantifying the Effect of Calorie Restriction on Saccharomyces cerevisiae LifespanKathryn Rouse, Hong Qin, HaoBo GuoDietary restriction (DR) increases lifespan in many organisms; however, its effect on individuals in genetically heterogeneous populations is unclear. Here, we are determining the effect of DR on lifespan for 166 gene deletion strains in Saccharomyces cerevisia. We fit the yeast lifespan data with the Gompertz aging model to find association factors for generating predictive models of lifespan genotype-dependent responses to calorie restriction.


U01An Analysis of the Mirai BotnetJames Hare, Li YangIn October 2016, many popular websites experienced one of the worst cyber attacks in history. Mirai, a new botnet which makes use of Internet of Things (IoT) devices, was deployed with an aim to take down the Domain Name System provider: DYN. During the attack many well-known services were inaccessible. These included; Netflix, Amazon, PayPal, CNN, Comcast, Pinterest, Starbucks, the Swedish Government, Twitter, and many more. In his research, We analyzed the nature of the attacks as well as the Mirai Botnet source code with an aim to understand more about cyber attacks which make use of IoT devices. We have also attempted to minimize the risk of future IoT attacks.

U02Virtual Tai-Chi, A Smart-Connected Rehabilitation Modality for Aging and DisabilityYu Liang, Dalei Wu, Zibin Guo, Nancy Fell, Amanda Clark, Dakila Ledesma, Samule Clark, William BakerThis work intends to develop an intelligent, four-dimensional (namely X-Y-Z plus somatosensory), partial control, and virtual-reality-enabled Tai-Chi System (VTCS). Tai-Chi is a traditional mind-body wellness and healing art, and its clinical benefits have been well documented. VTCS

integrates Tai-Chi with a series of cutting-edge computer technologies including 4D sensor technology, big-data, signal processing and analysis, human body kinematics, deep learning, virtual reality, and 4D-reconstruction, etc. The aforementioned system will generate a controllable and consistent 4D experience to help, push and coach (HPC) people to get involved in sports activities. In particular, VTCS makes Tai-Chi movements suitable to individuals who suffer from mobility disabilities due to diseases or injuries as an accessible rehabilitation and fitness modality. Under the support of collaborative hospitals, the physiological and psychological benefits brought about by VTCS will be critically assessed.

U03Influence of environmental conditions on fatty acid-induced changes in Vibrio cholerae persistence and pathogenicityAbigail Doyle, Reed Boeger, David Giles, Bradley HarrisVibrio cholerae is the Gram-negative bacterium that causes cholera, and its capacity to spread disease is due in part to its ability to adapt to the environment. These adaptations are potentially triggered by the uptake of exogenous fatty acids. Our objective is to identify the environmental conditions that initiate fatty acid-induced changes in V. cholerae persistence and pathogenicity.


UNDERGRADUATE RESEARCH

U04Remote access to a chemical engineering laboratory using internet of thingsHunter Eberle, Jerigray Eduave, Bradley HarrisUTC is developing a remote lab where users can connect to lab stations with personal electronic devices. Features include real-time control and monitoring of experiments, ranging from pump flow to chemical reaction kinetics, from anywhere, anytime.

Our main question: how do fatty acids present in its environment affect this bacterium’s ability to survive and spread disease?

U06Monitoring and Mapping of Underground Infrastructure using Augmented RealityAustin O’Byrne, Alay Patel, Suhail Arora, Dalei WuThe underground pipelines are critical infrastructure for all modern cities. These pipelines carry drinking water, waste and storm water sewage, natural gas, oil, electric power,

telecom cables, etc. However, many of them have unknown and typically aging conditions. Their locations are unknown and they have congested configurations. In this research, information extracted from collected data about conditions and locations of underground pipelines is interpreted and presented via Augmented Reality (AR) technologies. It is expected that the designed AR interface will provide desired information in an effective, timely and secure manner to utility managers, urban planners, and general users.

U07Stirred, Not Shaken: Design of a Chemically Powered Car for the AIChE CompetitionTyler Harp, Evan Patrick, Katie Chase, Michael Coleman, Braulio Ferrando, PaTrisha Jacobs, Hannah Margavio, Nick Peck, Lisa Phan, Dalton Strike, Dell ZimmermanStirred, Not Shaken is the Chem-E-Car that represented UTC at the southern regional AIChE conference in Baton Rouge, LA. The vehicle was powered by a magnesium/copper electrochemical battery, and utilized the iodine clock reaction as a stopping mechanism.

U08Brain Controlled Interface for Piloting DronesGrace McPherson and Tony FergusonWhat if a drone could be controlled without using a controller? Using the OpenBCI library and an EEG headset it is possible to pilot hands free. This research looks


specifically at motor and visual cortex signals as the input to control the drone. Unlike other similar projects which rely on machine learning to map the complexity of an individual’s brain, we are looking for repeatable patterns directly in the brain in order to universalize BCI for any form of control.

U09Autonomous Control of Swarm Robots Using Motion CaptureArtem MalashiySwarm robotics can be used to execute different missions cooperatively. There is a need for a small-scale replica of a swarm system to test the real-world application of techniques and algorithms used for cooperative swarm missions. An important function of robots in a swarm is inter-swarm communication - the ability to communicate an individual robot’s position to other robots in the swarm. There is currently a lack of small scale robots that are capable of performing communication needed for proper swarm flight. To simulate the intercommunication robots use in large scale swarm algorithms, a motion capture camera system has been implemented. This camera system (OptiTrack) is currently being developed in conjunction with Robot Operating System (ROS), a popular robotics middle ware that will coordinate the flight commands for the robots in the swarm. BitCraze CrazyFlie 2.0 quadrotor drones are being used for the small-scale swarm and a control system developed in CrazySwarm, a ROS package developed solely for use with CrazyFlies in swarm applications.


U10Automation of a BasketBallBot using LabVIEW and ArduinoNicolas Mateo, Jonathan RinkelThe objective of this research project is to fully automate a basketball robot that had been constructed by a previous research group. The robot is required to successfully recognize the presence of the backboard of a basketball goal. Once the backboard is recognized, the robot must position itself accordingly and detect the distance between itself and the backboard after performing redundant checks of the back. Using this distance, it will calculate how fast the ball will need to travel to reach the hoop before launching the basketball. The robot must complete these tasks at different distances while maintaining reasonable accuracy. The project is being undertaken using NI CompactRIO hardware powered by LabVIEW software with image recognition, and Arduino for some sensor processing such that the robot can complete its objective without any user input, demonstrating its ability to perform autonomously. Machine vision and other programming techniques will be implemented in conjunction with the onboard sensors to provide the robot with the necessary feedback to meet its requirements.

U11Feedback Control of a Haptic System using NI MyRIO HardwareBraxton Towry, Simar SinghHaptic technology allows operation of devices to recreate a sense of human touch onto computer simulations. Haptic devices allow its user to impart motions through a pendulum-like paddle, and read its output forces in one degree of freedom, which allows interactive simulations of virtual environments. Past research has proven that the sense of touch produced by haptic technology can be reproduced onto another robotic device, rather than a computer simulation. Through the use of a MyRio real-time embedded device, this work aims to replicate the movement of one Hapkit onto another using the LabView Instrumentational Workbench as a simple tool for control and data acquisition. When fully tested as being carried out in this research, it will serve as a platform for teaching, further experiments and future research projects in both biomedical and electrical engineering fields.

U12Distance Vectored CrazyFlie Swarm FormationsAnthony Ferguson, Scott A. Rinehart, Artem MalashiyThe objective of this research is to implement swarm methods using CrazyFlie drones. The application of swarms in this context is multiple aerial drones working in unison to stay in a given formation while moving to cover multiple areas. The drones are controlled by Robot Operating

System (ROS) in conjunction with an infrared cameras system, OptiTrack. The camera system will be able to track the drones by their different rigid bodies. Once the drone has been identified, the position will be sent to ROS. By varying the CrazyFlie PIDs, the drones will be able to maintain proper flight with the addition of optical tracking markers needed for OptiTrack. Once full connection has been resolved the drones can then move in formation flight staying connected. The formation will also adjust to the loss of a drone by adjusting their positions to maintain full connectivity.

This work is funded by a Faculty Research Grant and a Student SEARCH Grant.

U15Design of a Pneumatic Conveying Test Loop for Laboratory TestingNatalie Burdine, Ronald GouletPneumatic conveying is the transportation of material in a gas medium via a pressure differential. In industry pneumatic conveying is used to handle bulk solids and powders. The many variables required to establish design criteria for a conveying system make laboratory testing superior to theoretical design, therefore, instrumentation and apparatus for testing are paramount. This project investigates testing systems that allow for the collection of data regarding materials that are intended for conveying. A design for a testing apparatus, that can convey a wide range of materials, is proposed that allows for the collection of data regarding conveyed material in areas including flow, collisions, and particle integrity.

U16Protein Abundance and Longevity Correlation in Saccharomyces CerevisiaeBrittany Campbell Thomas, Lawrence TaylorRecent research has provided great insight in the understanding of the aging process, with yeast models

exhibiting the best candidacy for anti-aging. The study of calorie restriction has shown potential in effects of longevity in the lifespan of Saccharomyces Cerevisiae cells. Based upon the theory that removing certain genes can enhance the lifespan of the yeast cells is also circulating in current literature and can provide insight for future possible medicine. In our meta-analysis, we seek to find the relationship between average replicative lifespan of yeast cells with gene removal and the relative abundance of those gene proteins in yeast cell under calorie restriction.

This project is an exercise in engineering principles learned in the civil engineering curriculum. A unique concrete blend must be created that is light enough to float on water and strong enough to support the crew through a series of races. This project demonstrates the versatility and durability of concrete as a building material.

U20Rubens Tube: Demonstration of Acoustic Standing WavesThe development of the apparatus was initiated to engage students in learning and understanding acoustic waves. The apparatus was designed to be portable within acoustic constraints, easy to operate, demonstrate key acoustic characteristics, and be appealing to students ranging from elementary school to university level. The apparatus is

commonly known as a Ruben’s Tube, as it physically demonstrates (via open flames from a perforated tube) the relationship between sound waves and sound pressure.

U21The Response of Fuzzy Electronics to Ionizing RadiationSimar Singh, Dr. Daniel LovelessSmall satellites such as CubeSats operate under environmental constraints that are outside of typical commercial specifications. Such constraints include the ability to operate over an extended temperature range and during exposure to ionizing radiation. Due to flexibility and the ability to handle uncertainty, fuzzy logic is viable for satellite control while meeting the strict design requirements of a CubeSat. However, little is known about the response of fuzzy logic systems in the harsh space environment This work evaluates the response of fuzzy control logic to ionizing radiation and compares the response to that of conventional systems.

U22Numerical Prediction of Compressible Flow in an S-DuctHannah GiffordThe flow of high speed, subsonic, compressible fluid (air) through an S-duct is numerically simulated by solving the Navier-Stokes equations using Tenasi, a node-centered, finite-volume flow solver, developed at UTC. These simulations were carried out in support of UTC’s participation in the AIAA Propulsion Aerodynamics Workshop to be held at the AIAA Propulsion & Energy Conference in July 2018.

U23Modeling Silica Aerogel Optical Performance by Determining Its Radiative PropertiesHannah MargavioSilica aerogel is optically transparent and thermally insulating due to its unique porous structure. It is an ideal material for various solar-thermal applications. To model the optical properties, we call upon the radiative transfer equation (RTE). We can solve the integro-differential equation for the intensity field by Gaussian-Legendre Quadrature, a method of numerical integration. Python computes the intensity field using the method of numerical integration, and then solving for hemispherical transmittance and reflectance. We super impose the images to see the curves intersect at one point, giving an albedo and optical depth we can use to model the coefficients of scattering and absorption.
