F01Accessible Derby RacingEli Asher, Seth Cann, Chandler Gilreath, Vinent Jur, Christian Smith, C. WigalSpring Creek Elementary has many students with disabilities who have difficulty with understanding abstract concepts without participating in concrete, hands-on activities. One of the hands-on activities the students participate in is designing and building CO2 powered pinewood cars. They will race their cars in a Derby. The project team designed components to a track to help persons with disabilities to independently participate in the derby race.

F02Bus FidgetsThomas Dyr, Micah Sneller, Tyler Weaver, Mickael Young, C. WigalOrange Grove Center has students who ride the bus every day to and from their facility. Many of these students are fidgety, aggressive, bored, or loud while on the bus. This causes disruptions that annoy some of the bus occupants. It can also disrupt the bus driver. It was determined that an activity board (bus fidget) designed to attach to the back of the bus seats will help occupy students and thus make them less fidgety. The design of the bus fidget and its specific components are presented.

F03Interactive Play StationsDavid Gervolino, Eduardo Paez, Wendy Reynoso, Brandon Velazquez, C. WigalOrange Grove Center works with students who have autism, mood disorders, behavior problems, and cerebral palsy. The students are ambulatory and wheelchair bound. While the students move through the hallways on their way to classes and enrichment activities they are sometimes fidgety, aggressive, bored, or loud. This causes disruptions that annoy some of the other students in the hallways and classrooms. The team designed a set of interactive play stations for the large hallway space where the students can have a variety of sensory and physical experiences.

F04Jumbo Connect-4Ronald Brown, Chris Dahl, Eli Durant, Jonathan Freels, Holman Tanner, C. WigalOpen Arms Care (OAC) is in need of modified activities for their clients to engage in entertainment and learning. Many of the clients enjoy playing Connect Four in its typical table top format. However, there are those that cannot use the small table top version of the game but would benefit by playing a larger version of the game. Also, playing Connect Four allows for much needed engaging of sensory practices that are fun and encouraging for clients. This type of activity boosts the clients’ overall mental health. It was determined that playing a jumbo sized Connect Four game can also

FRESHMAN DESIGN PROJECTS


engage clients to use their arms and hands and thus provide high occupational therapy exercises that assist practice in fine motor skills, range of motion, and reaching. The design team presents their final design and build for the Jumbo Connect-4.

F05Mind Stimulating Activity Sensory WallMitchell Bauer, Walker Fannon, Noah Grigsby, Shelby Hash, Jamison Snuggs, C. Wigal A special-education teacher at Redbank Elementary School would like a sensory and activity wall in the classroom because the students need an easy and fun way to practice sensory and fine-motor skills. They presently are limited to their sensory activities. The design team chose to address this need by designing and building a mind stimulating sensory wall for the class room. This wall allows the students to safely develop their fine motor skills. The wall allows for exchanging sensory items for variety.

F06Sensory Activity - Lookout Valley Elementary SchoolZac Cavitt, Colton Landers, Andrew Lipe, Ellie Marty, Hayden Smith, C. WigalA special-education teacher at Lookout Valley Elementary School would like a sensory activity in her classroom because the students in the classroom need an easy and fun way to practice sensory and fine-motor skills. They presently have a limited amount of devices to provide sensory activity. The project team proposed a design solution allowing

students to move using steps and a ramp, either sit quietly in or move quickly through an enclosed space using a tunnel, and exercise senses using small sensory devices. That solution and the process that brought the students to this solution is presented.

F07The Slotted Wheelchair DeskDemi Alwalani, Jakob Lewis, Courtney Woods, C. WigalAn 11 year old boy at Chattanooga Valley Middle School (CVMS) uses a manual wheelchair and has severe communication delays. The boy sometimes becomes violent. During these episodes the boy reaches for people and can hurt them. The teacher would like a device that goes on the boy’s wheelchair to prevent him from reaching people. The team designed and built a wheelchair table and fins that prevent the child from reaching other students but allows him to use the chair and work with staff while in the wheelchair. It also provides him a place to work on puzzles which he greatly enjoys.


G01Allee Effects in Vibrio CholeraErick Rojas, D. Giles, B. Harris, J. Wang The research focuses on the potential risk associated with virulent spread of Vibrio cholerae. Headed by Dr. Jin Wang, a mathematical and computational simulation of pathogen dynamics is validated via experimentation and data collection focused on the transmission and pathogenic evolution of Vibrio cholerae. While the larger scope of the project is focused around the importance of understanding Vibrio cholerae to create control and management strategies that may prevent future outbreaks, this project focuses on the experimentation and subsequent data collection surrounding the growth mechanisms of the bacterium under various environmental conditions. In addition, future experimentation will also focus on assessing virulence changes at different stages under varying virulence-inducing conditions that mimic those of a human host.

G02Solar Thermal Energy Converter Using Air GlassLouie Elliott, Nisarg Hansaliya, Hannah Margavio, Evan Patrick, L. Elliott, S. YangWe fabricate a solar thermal energy converter prototype which converts natural sunlight using transparent aerogel. We demonstrate 250 C stagnation temperature without focusing natural sunlight.

G03Synthesis and Size Analysis of Bio-hybrid Nanostructures Armel Boutchuen, A. Arabshahi, S. PalchoudhuryHybrid nanostructures essentially integrate multiple nanoparticles into one unit to facilitate tailored material properties. We report a metric to assess these complex class of nanostructures.

G04Characterization of Nano Contamination: Challenges and FindingsSyed Tareq, J. BathiNano contamination (particulate contaminants of <100 nm) in surface waters is a growing concern worldwide. Due to their know high toxicity potential, it is important that nano contamination be detected and treated. Currently we are developing standard analytical techniques for nano contaminants detection in surface waters.

GRADUATE RESEARCH


G05City Modeling with Application in 3D Drone Delivery Transportation ProblemBabatunde Atolagbe, I. Fomunung, A. GhasemiDeveloping geometric and mesh generation techniques to create a 3D model of a part of a city. We use OSM database to access the details of building foot print and height. An efficient extrusion algorithm is developed to create walls and ceilings. The resulting surface mesh is guaranteed to be watertight and the generated nodes are unique. Potential applications of this technique is illustrated.

G06Decision Supporting Hydrodynamic Modeling of Tennessee RiverShuvashis Roy, J. BathiRiver simulation models can be instrumental in decision making process for scarce water resources management, if they are developed at a sufficient scale. Our research is exploring development and application of a 3D hydraulic and water quality model using EFDC program for the City of Chattanooga urban portion of Tennessee River below Chickamauga Reservoir, TN

G07Automatic Inferring of Cellular Lifespan from Time-lapsed Microscopic ImagesMehran Ghafari, H. QinMicrofluics based assay of yeast lifespan generate hundreds of microscopic images of trapped cells at different time points. We developed a machine learning methods to automatically infer the cell division events and infer family tree of cells, and thereby infer cellular lifespan.

G08Edge Computing Enabled Cognitive Portable GPRMaxwell Omwenga, William Rice, Y. Liang, D. Wu, L. YangAn edge computing (EC) framework for cognitive portable Ground Penetrating Radar (GPR) is proposed by considering computation offloading and communication resource allocation. The framework provides insight into the design of intelligent automated sensing systems enabled by edge computing.

G09Enhanced Underground Object Detection with Conditional Adversarial Networks Maxwell Omwenga, William Rice, Y. Liang, D. WuConditional generative adversarial networks (GANs) are investigated for underground object detection and identification. Time and frequency domain features of GPR data are considered in the design of GAN architecture and loss function.


G10GRRAndroid: Remote Live Forensics for Android at ScaleRuipeng Zhang, M. XieGRRAndroid is a logical data extraction and device triage system for large-scale remote live forensics of Android smartphones, which can be deployed in enterprises for incidence response, security auditing, and forensic investigation purposes.

G11Network Intrusion Detection System as a Service on OpenStack CloudChen Xu, Ruipeng Zhang, Mengjun Xie, and Li Yang In this project, Network intrusion detection system as a service (NIDSaaS) will be designed in OpenStack cloud environment, which provides NIDS service for the regular and administrative users of the cloud platform. Emerging Software-defined network (SDN) and Network Function Virtualization (NFV) technology are utilized in the NIDSaaS.

G12Network-Based Association Study of Protein SetsHaobo Guo, H. QinA method for network-based association study (NetBAS) had been developed to extract biological functions carried by protein sets. Fifty hallmark sets from the molecular signatures database (MSigDB) were analyzed using NetBAS,

which recognizes functional terms that were not identified by other tools such as DAVID. The method we present is useful in framework of the cellular interactomes.

G13Studying the Effects of Weather and Roadway Geometrics on Daily Accident Occurrence Using a Multilayer Perceptron ModelJeremiah Roland, Pete Way, M. SartipiWe combined different data relating to accidents (time, date, location, weather, roadway geometrics) into a single dataset. We use this dataset to predict where and when an accident will take place in the Hamilton county area, when provided with a time and location, with a 76% accuracy.

G14Urban Electric Vehicle Charging Markets: Computational Modeling and Optimal DesignSaroj Khanal, Sakineh Khalili, Farog Mohamed, Shailesh Wasti, V. Disfani, M. Ahmadi, M. SartipiMaximizing utilization of electric vehicle supply equipment (EVSE)—or electric vehicle (EV) charging stations—is still a challenge for cities like Chattanooga despite the emergence of EV station locators like PlugShare and ChargeHub. The missing key element in this market is the lack of data from the demand side of EVs, which often leaves EVs desperate for charging not connected while EVSEs are available nearby. This project computationally models and designs an infrastructure that simultaneously


gathers demand (EV) data—including desired destinations, connection period, and energy demand—as well as EVSE availability data to optimally match them to maximize social welfare.

G15Using Convolutional Neural Networks to Classify the Reproductive State of Digitized Herbarium SpecimensDakila Ledesma, H. QinThe digitization of natural history records, such as herbarium specimens, is generating a large dataset with many unexplored novel applications. A majority of these records are incomplete, lacking among other fields reproductive state information, a vital data point for large scale biological research questions. We present the ability of detecting the reproductive state of herbarium specimens using convolutional neural networks, and other machine learning techniques.

G16Agent-based Optimal Demand Response Shailesh Wasti, V. DisfaniPeak demand management is a pressing problem for utilities, which will be exacerbated with the addition of new types of load such as plug-in hybrid electric vehicles (PHEV). Conventional techniques of demand-side management (DSM)- smart pricing, critical-peak pricing – have failed to significantly improve the load curve. This project introduces a noble concept that incentivizes customers (players) to participate in DSM (market), which converges to global optima of energy schedule in what is called Nash

equilibrium. Simulation result shows that when the customers play their best strategies, the system’s peak-to-average, as well as customers’ electricity charge, is significantly reduced.

G17Automated Fuse Identification Within An Operational Smart Power Grid Aaron Wilson, D. ReisingThis project presents an automated hierarchical approach capable of identifying specific event causes using the electrical disturbance waveforms collected by field devices and stored using the COMmon format for TRAnsient Data Exchange (COMTRADE) format. The developed process has been implemented within EPB’s network, and is capable of categorizing a COMTRADE file as representing: valid data, a switching event, and electrical disturbances (e.g., faults and power quality disturbances). A single COMTRADE file takes roughly 1.78 seconds to process using the developed hierarchical approach. This automated hierarchical identification approach processes ALL events within an operational grid; thus, facilitating: prompt risk assessment, forecasting of disturbances that could lead to sustained faults and outages, efficient deployment of work crews to carry out repairs, increased protection against unwanted disturbances, as well as decreased risk to malicious targeted attacks carried out.


G18Connectivity Tracking Methods for a Network of Unmanned Aerial VehiclesJames Trimble, D. Pack, Z. RubleThe communication links shared among a team of Unmanned Aerial Vehicles (UAVs) can be represented as a Laplacian matrix. The second smallest eigenvalue of the matrix, known as algebraic connectivity, is a metric typically used to measure the connectivity of UAVs. Algebraic connectivity represents the robustness of the communication network. For an increasing number of UAV applications, varying levels of connectivity at different points throughout the duration of a mission are needed to meet operational requirements. Thus, the ability to track and obtain a desired connectivity profile over the course of a mission is critical. This work compares four different methods for increasing or decreasing the connectivity for a team of UAVs by adding or removing communication links between UAVs. A connectivity tracking algorithm was developed using these methods to track a profile of varying connectivity over time and an analysis of the results is provided.

G19Estimating the Effects of Small Voltage and Frequency Changes on Industrial Induction Motor LoadingAreeg Ahmed, Anas Ali, A. KarrarThis work develops expressions for estimating the change in active and reactive power for industrial motors in response to voltage and frequency variations around the operating point. Magnetizing circuit saturation is accounted for by

using incremental reactance. The expressions are simplified for a quick estimate using stator measurements and parameters. The expressions are validated using simulation, and further, a test was carried out in a nuclear power plant to determine the voltage sensitivities experimentally. Both simulation and test show that the expressions are capable of yielding a fair estimation of the required sensitivities.

G20Further Improvements in Voltage Stability CalculationsAreeg Ahmed, Anas Ali, A. KarrarThis work aims to speed up the predictor-corrector process for the voltage stability maximum power point estimation by using the P-index. An initial estimation is made through the P-index, and then a feasible point close to the estimation is found using a corrector step similar to the one in a continuation power flow (CPF). An updated estimation is then made using the results of the corrector step. The proposed method offers relatively high accuracy and it makes an enormous improvement to the CPF computation time.

G21Grid Integration of Solar PV Via Full-bridge Modular Multilevel ConvertersSaroj Khanal, V. DisfaniModular Multilevel Converter (MMC) has proved to be the most popular scheme for high voltage direct current (HVDC) applications, thanks to its salient features like modularity and scalability. Half-bridge MMC is widely adopted for those applications as it can serve its purpose simply and efficiently.


However, little attention has been given to exploiting the full potential of full-bridge MMC (FB-MMC) in grid integration application of photovoltaic systems. In this project, we propose a novel scheme based on leveraging its operating range which allows the flexible use of variable direct current (DC) link. This relaxation on dc bus voltage opens a new use of MMCs in grid-connected photovoltaic applications. We validate our system in MATLAB/Simulink and in hardware-in-the-loop (HIL setup).

G22Growth Model of Electric Vehicle Demand in ChattanoogaSakineh Khalili, V. Disfani, M. AhmadiGrowing interest in electric vehicles (EV) has established an inevitable demand for installation and smart operation of electric vehicle supply equipment (EVSE) – also known as charging stations. This project focuses on developing a growth model for EVSE structure in Chattanooga. The model proposed in this project will be developed using the EV and EVSE data gathered for Chattanooga in order to develop Chattanooga EV demand profiles for the next 5 years. To identify the behavior of empirical EV demand data and to forecast its growth in Chattanooga, the collected data is analyzed through correlation, regression and projection studies.

G23Ionizing Radiation Spectroscopy for In Situ Analysis and Prediction of Radiation Effects in Space ElectronicsBharat Patel, D.

G24Microgrids Energy Management Using Robust Convex ProgrammingOladokun Fuduyile, V. DisfaniEnergy Management System (EMS) is a very important concept especially with the evolution and rapid increase of Renewable Energy Sources (RES) and their impact on the utility-level scale grid in either a microgrid connected or isolated systems. A dedicated, reliable and sustainable EMS that is backed by a robust set of algorithms, which considers different adverse conditions and random demands of energy is the key/solution to ensuring existence of correlation between consumer demand of energy and the cost of generating the energy. The functionality and reliability of the EMS shall consider all aspect of the costs associated with the system for each of the variables - the costs of procuring energy for dispatchable Distribution Generation (DG), the


costs of storage or supplying energy to the system, and the costs associated with load shedding on each impacted node. It was concluded from the results obtained that correlation exists between the robustness nature of the EMS and its operational costs. The result also shows that the robust programming is flexible and less time-consuming when compares to the stochastic approach.

G27Reliability-aware Model Predictive Control for Modular Multilevel ConvertersSaroj Khanal, V. DisfaniModular Multilevel Converters (MMCs) have become worldwide standard of HVDC (High Voltage Direct Current) applications due to its salient features such as modularity and scalability. Switching has always been one of the most important issues in MMCs. Several switching methods have been proposed in literature, ranging from simple Sinusoidal Pulse Width Modulation (SPWM) to robust Model Predictive Control (MPC) based switching techniques. This paper proposes a novel reliability-aware switching algorithm to significantly improve the efficiency of widely adopted MPCbased switching techniques that utilized submodule (SM) voltage sorting algorithm. We validate the proposed algorithm for HVDC applications to analyze its control effort and performance in MATLAB/Simulink environment.

G28Small Unmanned Aerial Vehicles to Combat Malaria David Chen, Tony Ferguson, Jason McDowel, James Trimble, Stephen Weiler, T. Kline, D. Loveless, M. Loveless, D. Pack, Z. RubleWhile we have come a long way in reducing the incidence of malaria through the use of long-lasting insecticide treated mosquito nets (LLINs) and indoor residual sprays (IRS), the use of outdoor based interventions, such as larviciding, in


addition to the indoor preventative measures, can decrease, and possibly even eliminate, the number of malaria cases worldwide. It is infeasible, however, to continuously survey for standing water locations in expansive remote areas where malaria cases often crop up. Previous studies have shown small unmanned aerial vehicles (sUAVs) are cost effective in surveying large areas. These studies typically used single sUAV and required ground personnel to treat identified sites. Multiple sUAVs offer flexibility in mission planning and robustness in mission execution. In this proposed work, we use a team of sUAVs to survey an area for standing water, collect larvae samples and deploy environmentally friendly larvicide, bacillus thuringiensis subspecies israelensis (BTI). Sophisticated directional, vision and terrain observation technologies are planned to be integrated to penetrate dense canopy, locate previously hidden water larvae breeding sites and treat them with BTI. When combined with education, sanitation, extensive use of bed-nets and housing improvements, SUAV’s can potentially save thousands of additional lives in Malaria endemic areas.

G30The Impact of Rayleigh Fading Channel Effects on the RF-DNA Fingerprinting ProcessMohammed Fadul, D. ReisingThe Internet of Things (IoT) consists of many electronic and electromechanical devices connected to the internet. It is estimated that the number of connected IoT devices will be between 20 and 50 billion by the year 2020. The need for mechanisms to secure IoT networks will increase dramatically as 70% of the edge devices have no encryption. Previous research has proposed RF-DNA fingerprinting to provide wireless network access security through the exploitation of PHY layer features. RF-DNA fingerprinting takes advantage of unique and distinct characteristics that unintentionally occur within a given radio’s transmit chain during waveform generation. In this work, the application of RF-DNA fingerprinting is extended by developing a Nelder-Mead-based algorithm that estimates the coefficients of an indoor Rayleigh fading channel. The performance of the Nelder-Mead estimator is compared to the Least Square estimator and is assessed with degrading signal-to-noise ratio. The Rayleigh channel coefficients set estimated by the Nelder-Mead estimator is used to remove the multipath channel effects from the radio signal. The resulting channel-compensated signal is the region where the RF-DNA fingerprints are generated and classified. For a signal-to-noise ratio greater than 21 decibels, an average percent correct classification of more than 95% was achieved in a two-reflector channel.


G31BIM Based Building Renovation Cost AnalysisRaghda Mohamed, E.

G33Breaking Down Data Silos at Tennessee RandRandall McCallie, W. AbrhaThe purpose of this project was to break down (or combine) primary data silos at Tennessee Rand. The two aforementioned data silos: Master Schedule and Gantt charts are stored in two different and incompatible software platforms, Access Database and MS Project, respectively. Although both the data sets contain much of the same information (i.e., project dates), often both data silos are not maintained in order to keep parity. This leads to confusion and miscommunication regarding project timelines. Interviews with management members were conducted to study the types of data stored, and data was further studied to determine the availability of a software platform that would accommodate both data silos. The proposed solution is to use Smartsheet®, which has the capability to replace both the current Master Schedule (Access) and MS Project (Gantt charts) in one software platform.

G45Ultrasonic Radar in an Automotive ApplicationDaniel Landgraf, W. Sutton

Safety in automobiles remains chief among auto-manufacturer priorities for new vehicles entering the marketplace. Airbags, seatbelts and ABS braking systems have been proven as effective safety technologies. However, with electronic technology ramping up at an incredible rate, vehicle manufacturers are provided with an excellent opportunity to explore and implement potentially life-saving electronic

technologies into their vehicles. For this project, I will explore some possibilities pertaining to ultrasonic measurement and discuss how this technology is currently being implemented and perhaps look at new ways to use the technology. Additionally, I will consider the pairing of ultrasonic and wireless devices for mobile use in other applications. Sensitivity and repeatability are major factors in the success or failure of ultrasonic devices. Additionally, there are a large variety of name-your-need sensors available for use in conjunction with ultrasonic systems to increase their effectiveness, however, price is always a large factor and is the limiting factor for this project. I have purchased an electronics starter kit from REXQualis ($17), spare Elegoo breadboards ($9), a MakerHawk USB multimeter ($14), an Arduino WiFi kit ($25), an Anker USB Battery Charger ($19) and two (one for spare parts) Elegoo UNO Smart Robots ($55 each). Microsoft Excel Data Streamer is utilized for data recording and mapping (already owned – free). The purpose is to combine these basic and cheap units to prove the validity of ultrasonic use in automotive application by experimenting with theoretical calculations examining the ultrasonic time-of-flight techniques and comparing with actual results. Additionally, as an aside, I will explore the possibility of using this system in conjunction with a GPS to provide an additional resource in over-head line stringing or collecting actual time-of-flight data. The goal is provide vehicle or other equipment operators with the ability to see without seeing by taking advantage of the growing mechatronic technology.

S28A Conveyor System FailureCalvin Robinson, Travis Walker, W. AbrhaThe purpose of this project is to study and address the failures of conveyor systems within Roper Corporation. The failures often result in unplanned downtime. From January 1st, 2018 to March of 2019, a piloted process accrued 231 minutes of downtime, which equates to around $35,000 of loss of production. After conducting a Root Cause Failure Analysis (RCFA), we determined that the causes of conveyor failures are related directly to Maintenance Practices and Procedures, Operating Practices and Procedures, and the Equipment Design. The issue requires strategies to eliminate such breakdowns and loss of production. It is suggested that through conducting a Condition Based Monitoring procedure, data could be gathered to determine exactly when to replace damaged components to prevent unplanned downtime due to failures. Autonomous Maintenance procedures could help reduce the risk of conveyors failures by cleaning the equipment of loose screws, insulation, and other outside variables daily. Lastly,


conducting an engineering change could help to eliminate the risk of the types of conveyor failures. The combined impact of these strategies is to improve the reliability of the conveyors and ultimately improve OEE.

MargravesThe University of Tennessee at Chattanooga (UTC) Mechanical Engineering Senior Design Rocket Mocs Team has entered the National Aeronautics and Space Administration (NASA) Student Launch Initiative (SLI) competition for the first time this year. The design goals are to launch an airframe between 3,500 and 6,500 ft AGL and predict the apogee as closely as possible while carrying a payload to be deployed. The selected payload for UTC was the drone which must fit (fold) in the airframe and carry a simulated GPS beacon to a location disclosed after launch.


S40Improving Nurse Scheduling for Effective Emergency Department (ED) OperationSarah Thomas, Monica San Juan Garcia De Eulate, Cecelia WigalPatients 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. This project uses simulation to identify an optimal daily nursing staff schedule for the main campus of CHI in Chattanooga. Data from a year of ED arrivals and the ED process were studied to help develop the simulation process and arrival and activity rates.

S41System Flow and Filtration Development for a Mid-Scale Aquaponics SystemChristopher Cleek, Matthew Cogdell, Amanda George, Jonathan Geva, Brett McNealy, T. ElliottThis design team was charged with reestablishing an aquaponics system created by previous UTC design teams. The system required flow analysis and pumping system changes to meet fluid transfer rates required to sustain life in the system. Additionally, the team was charged with investigation and design changes to the sump filtration system to reduce biological waste impacts while keeping tank debris to a minimum.

S42The Happinest AviaryZuhair Alelq, Mushabbab Alqahtani, Branton Mathues, Elliot Ziebart, T. ElliottHappinest Wildlife Rehabilitation and Rescue requested assistance from UTC in support of prosthetics for injured birds. While reviewing that request a need for additional design support was realized. Currently this nonprofit organization operates out of the primary operator’s home, and most wild life, particularly birds, are housed in cages in a standard garage. This UTC design team set out to change that by designing an aviary to be constructed in the operator’s back yard. The design would include considerations for bird flight, feeding, watering and cleaning.

S43Torsion Tester Development for Shape Memory AlloysClayton Bennett, Luis Ortiz, Jeff Parker, Wilbert Young, M. Mahtabi, T. ElliottShape Memory Alloys (SMAs) are alloys that “remember” their original shape such that when they are deformed and heated they return to that shape. UTC CECS has begun research in this materials area and in support of this research interest a senior design team was charged with developing a torsion testing device for very small diameter SMA shafts and tubes.


S44Wire Braiding System Optimization for Medical DevicesWaleed Abdulnasser, Juan Hernandez, Dustin Howard, Kayla Sneed, T. ElliottInteger has had a long standing relationship with UTC CECS which has recently expanded to the wire braiding aspects of their manufacturing processes. Making such items as coronary catheters and guidewires the organization came with a wire braiding issue requiring scrape reduction. The student lead design has been developed and simulated while it awaits approval for adoption. Preliminary data shows a scrap reduction greater than 30%.

U03Effects of Environmental Conditions on Vibrio Cholerae Virulence Factors in Static and Continuous CultureKyle Barton, Abigail Doyle, Konner Glass, Dalton Strike, B. HarrisFood- and water-borne enteric pathogens kill approximately 2 million people each year, pose ongoing threats to developing countries and have emerged recently in the United States. Perhaps the best known of these is the Gram-negative bacterium Vibrio cholerae, which is the causative agent of the acute intestinal infection commonly known as cholera. During infection, V. cholerae colonizes the

epithelial layer of the small intestine and secretes a potent enterotoxin that causes the severe diarrhea associated with the disease. The primary objective of this research project was to cultivate V. cholerae in a continuous culture (bioreactor) under controlled conditions in order to better understand how it senses and adapts to its environment in order to spread disease.

U06Modeling Silica Aerogel Optical Performance by Determining its Radiative PropertiesNisarg Hansaliya, Hannah Margavio, Evan Patrick, S. YangTo better understand aerogel’s optical performance, we decoupled and quantified the extinction contributions of absorption and scattering separately by identifying two sets of radiative properties. The radiative properties are deduced

UNDERGRADUATE RESEARCH


from the measured total transmittance and reflectance spectra (from 250 nm to 2500 nm) of synthesized aerogel samples by solving the inverse problem of the 1-D Radiative Transfer Equation (RTE). The obtained radiative properties are found to be independent of the sample.

U07Remote Access to an Absorption Column and a Pump Flow Station Using Internet of ThingsShelby Musselman, Erik Loredo, B. HarrisThe onset of information technology has brought about swift changes in manufacturing and how things are made, and smart, connected products continue to change the industrial landscape. Here, we discuss how the Dr. Jim Henry Chemical Engineering and Controls Systems Laboratory is continually being renovated to keep pace with advances in cyber-physical systems. The ultimate goal is to enable users to monitor and control lab station experiments remotely using their personal devices (e.g., laptop, tablet, smartphone.)

U08Using Elementary Mode Analysis to Design a Minimal Strain of E. Coli for the Overproduction of Hydrogen Peroxide Will Khomtchenko, B. HarrisCurrently, over 90% of chemicals produced in bulk today are derived from petroleum, which is a non-renewable resource. A potential alternative is the use of living organisms as engineered cellular factories to produce chemicals. Designing cellular factories for optimal yields remains challenging due to the large number of inefficient pathways,

high amounts of side-product formation and the fragility of the cell’s metabolic network. In this project, we used a computational framework to arrive at an optimal design of Escherichia coli for the production of hydrogen peroxide, which is currently derived from petroleum. The objective of this project was to provide a proof of concept that metabolic modeling techniques can be used to efficiently design cellular factories to produce chemicals that are currently being derived from petroleum.

U09Water Harvesting Using Solar EnergyEvan Gildernew, Eathan Lee, Sungwoo Yang, S. YangThis project focused on conducting computational analysis on coupled heat and mass transport equations in Python to discover efficiencies within the design of inter and intra crystalline diffusion and the thermal transport through the layer. The computational model was developed within a Python package called FiPy. FiPy performs object oriented partial differential equation solving based on the standard finite volume (FV) approach.

U10Engineered Nanoparticles: Microscopic Miracle or Pint Sized Pollutant?Patrick Craig, Steven Sawyer, J. BathiCurrent increased use of engineered nanomaterials (ENMs) is expected to lead to their increased release to surface waters. Keeping in mind potential of high ENMs in surface runoff, we are working on characterizing their occurrence, properties and treatability in urban water settings. While targeting most


common source area land uses of urban runoff, we are evaluating ENMs treatability by promising adoption media material. Column studies are being used to gain insights on the retention of ENMs by bio-retention media.

U11Modeling of Redundant Reeving HoistMorgan Young, A. Ghasemi, R. GouletIn an ongoing effort, the research team is simulating the failure of an advanced double safety crane mechanism. In this situation, an unknown dynamic load factor is generated which is damped by an equalizing bar. The sponsor needs to know if the chosen equalizing bar is enough to damp the dynamic load factor or not. Toward this end, the entire crane mechanism which includes the drum, the traveling block, and a set of pulleys are modeled in 3D. This helps the research team to accurately compute the properties of the system such as length scales and mass moment of inertia which are required for dynamical simulation.

U12A Deep Learning Approach to Estimate Replicative Lifespans from Yeast CellJustin Clark, H. QinWe test a simple baseline convolutional neural network (CNN) architecture, a more sophisticated and deep CNN architecture called SimpleNet and a new neural network architecture called a capsule network. We found that the different models have diverse and complementary errors, so we developed an ensemble of models that combine the single models which led to high overall accuracy, precision and recall.

U18Development of Mechatronic SystemJames Beal, Noah Grigsby, A. NasabThe manufacturing practices of today’s advanced industries are going through a significant change in machine-to-machine and human-to-machine communications. The collective set of the new trends in these practices is called

Industry 4.0 which fosters the notion of a “smart factory.” Within modular structured smart factories, cyber-physical systems monitor physical processes, create a virtual copy of the physical world and make decentralized decisions. Over the internet of things, cyber-physical systems communicate and cooperate with each other and with humans in real- time both internally and across organizational services offered and used by participants of the value chain.

U19Design of a Device to Make Drinking Water from Thin Air for Remote Regions by Use of Solar EnergyJonathan Dennis, Dallas Elrod, Jonathan Geva, Kristian Karl, Kassedy Whitener, P. DamshalaSeveral million people in underdeveloped nations live without having access to drinking water. Commercial products are available that make water from thin air, but it requires access to electric power. Students of this design project performed engineering analysis to design a device that is powered by solar energy using PV panels. The estimated capital cost of producing water is about seven cents per liter of water.

The payback period for this system is estimated to be encouragingly very low with zero emissions of greenhouse gases

U21Rocket Mocs - National Association of Rocketry Level 1 CertificationT. ElliottIn support of the UTC Rocket Mocs Team, the faculty advisor applied for a High-Impact Practices Development Grant. The project was to train students on the Rocket Mocs team in the senior design class to understand high powered rocketry (HPR), learn safety codes, develop construction knowledge, experience launch site procedures, and make flight attempts to earn Level 1 certification with the National Association of Rocketry (NAR). This project also allowed us to form relationships with local sites for competition launch activities as well as establish a local section of NAR in Chattanooga, Scenic City Missile Works (SCMW).

U22Watering Device SensorsStephan Rodemann, W. Sutton One thing that many people forget on their travels is that their home plants are not going to be tended to. This project will focus primarily on a do it yourself set up using readily available sensors and a single-board micro controller such as

an Arduino. The ultimate goal is to implement this device into an autonomous watering system that uses the specified information and take the appropriate actions to correct them.

U25VIGOR A Virtual, Individualized and Generative Orchestrator for RehabilitationDakila Ledesma, Anthony Skjellum, Yu Liang, DaleiWu, ZibinGuo, Nancy Fell, Amanda ClarkPhysical inactivity is a major national concern, particularly among individuals with chronic conditions and/or disabilities. There is an urgent need to devise practical and innovative fitness methods to achieving Virtual, Individualized, and Generative Orchestrator for Rehabilitation (VIGOR). VIGOR aims to enable users an intelligent, four-dimensional (namely X-Y-Z plus somatosensory), partial control (e.g., phantom limb), and virtual-reality-enabled generative modality.

U26An Analysis and Proposed Improvement of Hamilton County VW eLab EquipmentChantz Yanagida, W. Sutton16 schools in Hamilton County received funding for VW eLab equipment, including Computer Numerical Control (CNC) router (Shopbot PRS 96x48x6), Laser Cutter (Zing Laser, Dremel LC40), Fused Deposition Modelling (FDM) 3D printers (Prusa i3 Mk2S, Dremel 3D40), Vinyl Cutters (Roland GS-24). These items, with some additions, are being integrated into distinct curricula within each school, providing students an opportunity to develop skills within the field of design and fabrication, when the equipment is functional. However, until this point, there has been little insight on broken and depreciating equipment within such labs. Here we look at sustainabilty with sometimes heavily utilized K-12 curricula that can push both the equipment and the specialists to the

limit. Here more specifically, we focus on the 3D printers, which had experienced a state of disrepair. Common issues were jamming and poor printing quality. It was noted that 15 out of 32 of the 3D printers needed repair which ranged from calibration errors to LCD Screen replacement. The purpose of this paper is to quantify potential issues within common equipment found within digital fabrication labs, in addition to providing a mechanical improvement to fix the most common issue with the 3D printers.

U27Force Analysis on a Baja CarBrett McKinney & Jason DeHay, W. SuttonWhen designing the Baja car, a common problem occurred when trying to preform finite element analysis on structural components. The problem occurred when analyzing the factor of safety of the components. The force acting on the members is almost always unknown, there is no database for average forces exerted on small off-road vehicles. The main purpose of this experiment is to find an accurate range of values of forces and strains acting on the front suspension of the 2019 Baja vehicle. If successful, this experiment will provide accurate values of suspension load and control arm strain to be used for finite element analysis and factor of safety simulations. This experiment will also be used to relate linear shock displacement to acceleration of the knuckle and strain in the lower control arm. This information can be used as a useful tuning tool to optimize shock adjustments.

The apparatus for this experiment will be composed of an Arduino Mega 2560 microcontroller, a 200-millimeter linear potentiometer, a 3-axis accelerometer, and a strain gauge.


The linear potentiometer will be fixed to the shock absorber to measure linear compression and extension. The accelerometer will be attached to the knuckle and used to measure impact forces transferred from the road into the suspension. The strain gauge will be fixed to the lower control arm to measure strain caused by the upward impact forces from the road acting against the downward force of the shock absorber. The Arduino will be powered remotely on the vehicle with a battery pack while storing data on an SD card for later analysis.
