Radar Network Synchronization And Imaging Using Semiconductor Laser System, Meesha Gupta
Honors Theses
The purpose of this project is to report the software implementation of radar network synchronization and imaging using a semiconductor laser system. We compare different radar configurations and methods to generate laser chaos.
The monostatic radar configuration has limited capabilities of detecting targets with low radar cross-sections. This configuration is also vulnerable to intentional interference. In contrast, a radar network where multiple radar transceivers (nodes) are placed strategically can yield superior detection. This radar network can also extract additional information about the target, such as its size and shape. However, synchronizing the nodes in the radar network poses a significant …

Orthopedic Anti-Plunging With External Cooling Drill System, David Bates, Nick Muro, Olivia Bresett, Laura Wind
Honors Theses
There are 22 million orthopedic surgeries performed globally each year and this number is expected to increase by approximately 6 million by 2022. Within many of these operations, surgeons are required to utilize orthopedic drills to properly insert various implants to facilitate healing within the body. Unfortunately, many of these procedures have complications that result in thermal osteonecrosis or bone plunging. These complications cause the death of bone cells due to heat and the loosening of an implant from drilling through the entirety of the bone, respectively. To help prevent these detrimental issues, we seek to redesign the orthopedic drilling …
Iot Garden Frost Alarm, Andrew James
Iot Garden Frost Alarm, Andrew James
Honors Theses
Home gardeners are faced with yearly challenges due to spring frosts harming young plants. This is frequently mitigated by covering crops with frost blankets, but only on nights when a frost is predicted. In areas with less predictable climate, an unexpected frost can kill vulnerable plants, reducing the amount of food produced. A system is proposed and designed here to use internet of things (IoT) technology to enable a small weather station in the home garden to report current climate data and predict frosts, then alert the gardener in time for them to cover their plants.
The system as designed …

In Sub-Saharan Africa, 1 in 5 children are admitted to the hospital due to below average levels of oxygen in the blood caused by respiratory illnesses such as pneumonia. Other acute lower respiratory infections account for 1.4 million deaths annually in low resource areas. Pulse oximetry is commonly used to measure oxygen saturation levels, specifically for those with compromised respiratory conditions, to make sure that enough oxygen is being transported to the extremities. Low resource countries face many challenges to access pulse oximeters, mainly due to cost and durability of the device. This lack of oximeters decreases the ability to …
The Great Equalizer Or A Modern Iteration Of Historical Inequality: Artificial Intelligence In Latin America, Santana Amaker
The Great Equalizer Or A Modern Iteration Of Historical Inequality: Artificial Intelligence In Latin America, Santana Amaker
Honors Theses
In recent years, governments across Latin America have taken steps to foster the development and implementation of artificial intelligence causing an expansion of the use of AI in the region. For instance, countries like Colombia and Argentina are using AI in their judicial systems. Superficially, the allure of AI in the judicial system stems from the thought that AI is an impartial entity that will pass fair and unbiased judgement. However, just like the programmers responsible for creating AI, algorithms used in AI system can be biased. The reason being AI is often trained to make predictions or decisions based …

Development Of A Computational Framework For Estimating Knee Joint Contact Forces In Running, Sean W. Kapp
Development Of A Computational Framework For Estimating Knee Joint Contact Forces In Running, Sean W. Kapp
Honors Theses
The prevalence of running as a form of exercise and the necessity of walking for simple locomotion obscure massive forces and moments within the body. An especial area of concern is the knee, as common among these injuries is knee pain as a result from high impact on the ground or ground reaction forces. These forces are altered by the foot strike pattern of the individual; in this study, either rearfoot strike (RFS) or forefoot strike (FFS). This alteration will impact internal forces conducted upward through the body. Given the complexity of the motion of running and the forces involved, …

Chaos-Based Coffee Can Radar System, Conor Willsie, Rong Chen
Honors Theses
Linear frequency modulated (LFM) radar systems are simple and easy to implement, making them ideal for inexpensive undergraduate research projects. Unfortunately, LFM radar schemes have multiple limitations that make them unviable in many real-world applications. Given the limitations of LFM radar systems, we propose a chaos-based frequency modulated (CBFM) system. In this paper, we present the theory, design, and experimental verification of a CBFM radar system that has both ranging and synthetic aperture radar imaging capabilities. The performance of our CBFM system is compared to that of the LFM system designed by MIT. We document many challenges and unforeseen obstacles …

Immunomodulatory Biomaterials For Cancer Immunotherapy, Larry Donnell Stokes Jr
Honors Theses
Cancer immunotherapy has become an effective treatment in the toolbox of oncologists. Immunotherapy offers a less toxic alternative to standard cancer treatments such as chemotherapy and can have prolonged curative effects to decrease cancer recurrence. Today, many drugs and biological agents have been developed that target the immune system and elicit an antitumor/cancer response. These agents are known collectively as cancer immunotherapies. While immunotherapies have radically improved treatment outcomes for many cancer patients, there are drawbacks to using these treatments. Immunotherapy treatments have poor clinical responses in patients with tumors that lack immunogenicity. Some of the treatments also pose a …

Molecular Mechanisms Of Oxidative Stress On Molecular Motors, Addison Caspari-Linhardt
Honors Theses
Astronauts encounter many forms of ionizing radiation during space travel. Ionizing radiation has been seen to cause cancer, cataracts, radiation sickness, tissue damage, hereditary effects, and damage to the central nervous system. Ionizing radiation can damage DNA molecules through oxidation, as well as other vital proteins like molecular motors. Kinesin-1 is a molecular motor protein that essential to intracellular transport. Microtubules serve as the “roadway” for kinesin transport, where kinesin converts chemical energy from ATP hydrolysis into mechanochemical “steps” to move along the microtubules. Optical trapping has been used in previous research to measure single kinesin motor properties. We have …
Effects Of Static Mixer Geometry On Polyurethane Properties, Christian R. Dixon
Effects Of Static Mixer Geometry On Polyurethane Properties, Christian R. Dixon
Honors Theses
The field of additive manufacturing has gained significant academic interest in the past few decades with a recently developed type of three-dimensional (3D) printing. Reactive extrusion additive manufacturing combines precursor materials within a static mixer (SM) head, where polymerization begins before deposition. Variable static mixer geometries currently exist, but the relationship between mixer geometry and post-polymerization mechanical properties is undefined. To elucidate this relationship, a series of experiments with identical chemistry was performed using a high shear SM, a low shear SM, and a comparative batch reaction. While higher shear mixing trends with faster polymerization for step-growth polymerizations, consistent precursor …
Utilizing The Oxygen-Barrier Properties Of Poly(Isobutylene) To Enhance Photon Upconversion In Thermoplastic Elastomers, Haley Carroll
Utilizing The Oxygen-Barrier Properties Of Poly(Isobutylene) To Enhance Photon Upconversion In Thermoplastic Elastomers, Haley Carroll
Honors Theses
Upconversion (UC) is the conversion of low energy light to higher energy light. It is utilized for a broad range of applications such as solar energy harvesting, microscopy of cellular biology, and cancer therapy. Specifically, triplet-triplet annihilation UC (TTA-UC) involves two dye species, a sensitizer and an annihilator, which are capable of upconverting noncoherent light such as sunlight. Traditionally, TTA-UC is achieved in solution, rubbers, or glasses, however, this work probes the capabilities of a thermoplastic elastomer (TPE) matrix to examine the effect of phase-separated morphology on the energy transfers necessary for TTA-UC. The system herein consists of poly(styrene-isobutylene-styrene) (SIBstar) …
An Open-Baffle Motional Feedback Loudspeaker, Matthew Quinlivan, William Harvie
An Open-Baffle Motional Feedback Loudspeaker, Matthew Quinlivan, William Harvie
Honors Theses
A dynamic loudspeaker mounted in an open baffle has the same parameters as a loudspeaker in free space. A subwoofer mounted in an open baffle has a small total quality factor and therefore the frequency above which the driver has a significant output is too high despite the subwoofer's low resonant frequency. To address this issue, we implemented a motional feedback circuit with the goal of introducing both velocity feedback and acceleration feedback into the loudspeaker system and thus altering the resonant frequency and total quality factor of the system. After verifying the efficacy of our feedback circuit with computer …
