Evaluation Of The Dynamic Vision Sensor’S Photoreceptor Circuit For Infrared Event-Based Sensing, Zinah M. Alsaad

Electrical and Computer Engineering ETDs

For space surveillance applications, neuromorphic imaging is being studied as it may perform sensing and tracking tasks with less power and downstream datalink demand. The read-out of the event-based camera is made to only be sensitive to changes in the signals it receives from the photodetector, which results in a datastream of events indicating where and when changes in illumination occur. This is in contrast to the conventional framing camera, which produces images by essentially counting the electrons produced by light incident on each pixel’s photodetector. These cameras are commercially available with siliconbased detectors for applications involving visible wavelengths. However, …

Chance Constrained Stochastic Optimal Control Of Discrete Time Linear Stochastic Systems With Applications In Multi-Satellite Operations, Shawn Priore

Electrical and Computer Engineering ETDs

Stochastic disturbances arise in a variety of engineering applications. For tractability, Gaussian disturbances are often assumed. However, this may not always be valid, such as when a disturbance exhibits heavy-tailed or skewed phenomena. As autonomous systems become more ubiquitous, non-Gaussian disturbances will become more common due to the compounding effects of sensing, actuation, and external forces. Despite this, little has been done to develop formal methods that are both computationally efficient and allow for analytical assurances with non-Gaussian disturbances. Addressing convex polytopic set acquisition and non-convex collision avoidance chance constraints with quantile and moment-based reformulations, this dissertation proposes novel stochastic …

Leipzig Applicator Dose Study Progress And Mesh Computational Phantoms, Julianna Davis

Undergraduate Research Competition

Leipzig applicators are tools used to administer brachytherapy, which is a treatment for skin cancer that is typically used when it occurs on the face of the patient. This treatment requires the patient to have lead shielding over their eyes to protect the sensitive lenses. This study is in the progress of modeling this scenario in order to determine the radiation dose delivered to the patient’s eyes due to the lead shielding. This is being done in a Monte Carlo computational radiation transport program, EGS (Electron Gamma Shower,) which was previously unable to handle mesh computational phantoms. After working with …

Nanoscale Mechanics Of Li Anodes In Solid-State Li Batteries, Md Takmil Sakir

Student Research Symposium

Solid-state Li metal batteries have emerged as a promising way to enhance energy density and safety compared to the traditional Li-ion batteries. Even though numerous research studies are being conducted in this field, many unresolved issues have been hindering the commercialization of such batteries such as dendrite formation, loss of contact, battery failure in low cycles, etc. One of the reasons is the lack of knowledge on the deformation mechanisms (especially creep) at the atomistic level. In this study, Molecular Dynamics simulations have been performed and the creep behavior and superplasticity of pure Lithium was observed in nano scale. Grain …

Advances In Alkaline Water Electrolysis And Way Forward: A Review, Manjur Basnet

Student Research Symposium

Low cost and large stack manufacturing have favored the commercialization of low temperature Alkaline Electrolyzers (AEL). However, due to the nature of its operation at lower current density and temperature, AEL systems have a lower hydrogen production rate and efficiency as compared to its counterparts, PEM (Proton Exchange Membranes) and SOE (Solid-Oxide Electrolysis). Studies related to the use of higher temperature and use of advanced materials for diaphragm and electrocatalysts have been conducted. These studies are aimed at improving the performance of AEL systems without significantly increasing the cost. This study focuses on a review study of the existing technologies …

Improving Intersection Safety With Geographically-Targeted Crash Prediction Models In Utah, Atul Subedi

Student Research Symposium

This project aims to improve intersection safety in Utah by developing geographically-targeted crash prediction models. The lack of research investigating active mode crashes at signalized intersections in different geographical regions calls for this study. The objective of this research is to understand the factors associated with the frequency of active mode crashes at signalized intersections. Exposure variables such as AADT, pedestrian and bicycle volumes, and intersection-level variables such as crossing distance, speed limit, and presence of street lights were analyzed using a negative binomial regression model.

A Unified Approach That Makes Online Taxi Service More Effective, Jiyao Li

Student Research Symposium

We propose a unified approach for scheduling taxis across a city. Balancing the supplies and demands on a city scale is a challenging problem in the field of online taxi services. To tackle the problem, we design a unified approach considering two important processes: Taxi-Rider Matching and Taxi Guidance. In the Taxi-Rider Matching, with the help of Lottery Selection (LS) and smoothed popularity score, the approach can balance supplies and demands well, both in the local neighborhood areas and hot places across the city. Regarding Taxi Guidance, we propose Q-learning Idle Movement (QIM) to direct vacant taxis to the most …

New Rocket Fuel Blend For Hybrid Rocket Ignition Enhancement, Ryan Thibaudeau

Student Research Symposium

This work describes and compares different methods of ignition for hybrid rockets using acrylonitrile butadiene styrene (ABS) as the fuel and high-test hydrogen peroxide (HTP) as the oxidizer. Additionally, the work provides an overview of the current state of the art regarding ignition of HTP hybrid rockets. The approach to ignition methods using gaseous oxygen (GOX) pre-lead and catalytic ignition configurations are presented. The manufacturing process and testing results of a unique catalyst-infused fuel grain is presented as the optimal solution to overcome ignition latencies present in HTP-ABS hybrid rockets.

Understanding And Minimizing The Effects Of Propellant Mean Bulk Temperature Changes In Solid Rocket Motors, Thomas Sorensen

Student Research Symposium

Solid rocket propellant typically contains the geometry of an extruded annulus. This propellant, when ignited, burns radially at a rate called the “burn rate”. This rate dramatically affects important motor performance characteristics such as pressure, thrust, and specific impulse. Each different mixture of solid rocket propellant has a sensitivity to initial propellant temperature. The relationship between burn rate and initial temperature sensitivity function are each determined experimentally. This literature review will analyze existing experimental data. The objective of the research is to see if there is a reliable way to predict the burning rate’s temperature sensitivity prior to obtaining new …

Reclaiming Fault Resilience And Energy Efficiency With Enhanced Performance In Low Power Architectures, Noel Daniel Gundi

Student Research Symposium

Shrinking technology node and the massive increase in data workloads has witnessed a swift migration of the system towards the Low-Power Computing (LPC) paradigm. Additionally, to accelerate the redundant yet mammoth AI instructions, novel ASIC design architectures have been explored. Google’s Tensor Processing Unit (TPU) is one such architectural innovation deployed in the commercial space to speedup the processing of AI workloads. In an effort to achieve a superior energy efficiency, Near-Threshold Computing (NTC) has been marginalized to be an efficient LPC paradigm. Due to an underscaling of voltage, NTC offers quadratic savings is power consumption in comparison to operating …

Controlling Oxidizer-Fuel Ratio With Vortex Injection In Hybrid Rockets, Max Francom

Student Research Symposium

Hybrid motors have existed as a hypothetical propulsion system for decades in a wide range of upper stage rocket motors due to their simple, robust, non-toxic, and versatile nature. However, inherent to hybrids is oxidizer:Fuel ratio (O:F Ratio) shift over time, the elimination of which would remove many potential barriers to hybrid rocket motor usage in most spaceflight applications. The most important and difficult part of analytical models of hybrid rockets is the regression/combustion rate of hybrid fuel. O:F Ratio control is fully dependent on the ability to manipulate this regression independently of Oxidizer mass input. One potential method of …

In-Situ Optical Measurements Of Combustion Plumes, Cara Frischkorn

Student Research Symposium

The exhaust plumes of rocket and jet propulsion systems feature highly-oxidizing, potentially corrosive, extremely high temperature flows. The hostility of these environments makes obtaining in-situ thermal flow measurements extremely difficult. The conventional method for these measurements uses Gardon heat-flux gauges requiring complex and highly invasive installations which cannot be used for flight applications. More recent work has used fiberoptic cable installations to sense internal flow conditions of hybrid and solid fuel rockets. In this configuration, fiber optic cables inserted through the fuel and into the flow are consumed by the flame as the fuel surfaces pyrolyze, but the cable tips …

A New Framework To Assess The Individual Fairness Of Probabilistic Classifiers, Muhammad Fawad Akbar Khan

Student Research Symposium

Fairness in machine learning has become a global concern due to the predominance of ML in automated decision-making systems. In comparison to group fairness, individual fairness, which aspires that similar individuals should be treated similarly, has received limited attention due to some challenges. One major challenge is the availability of a proper metric to evaluate individual fairness, especially for probabilistic classifiers. In this study, we propose a framework PCIndFair to assess the individual fairness of probabilistic classifiers. Unlike current individual fairness measures, our framework considers probability distribution rather than the final classification outcome, which is suitable for capturing the dynamic …
