Passive Positioning Using Linear Multilateration, Eric R. Widdison
Passive Positioning Using Linear Multilateration, Eric R. Widdison
Theses and Dissertations
Passive localization of aircraft in flight using signal time of arrival (TOA) poses some unique challenges. The sensors must be deployed in an approximately coplanar configuration, which produces significant vertical uncertainty in the estimated position. This dissertation examines the traditional algorithms used in passive localization. It presents general forms of linear TOA, time difference of arrival (TDOA), angle of arrival (AOA), and frequency difference of arrival (FDOA) equations from the literature and explains how to apply an intuitive geometric interpretation of these equations. It presents two novel algorithms for passive localization. One uses a one dimensional AOA (1AOA) to improve …
Design, Determination, And Evaluation Of Gender-Based Bias Mitigation Techniques For Music Recommender Systems, Sunny Shrestha
Design, Determination, And Evaluation Of Gender-Based Bias Mitigation Techniques For Music Recommender Systems, Sunny Shrestha
Electronic Theses and Dissertations
The majority of smartphone users engage with a recommender system on a daily basis. Many rely on these recommendations to make their next purchase, download the next game, listen to the new music or find the next healthcare provider. Although there are plenty of evidence backed research that demonstrates presence of gender bias in Machine Learning (ML) models like recommender systems, the issue is viewed as a frivolous cause that doesn’t merit much action. However, gender bias poses to effect more than half of the population as by default ML systems are designed to cater to a cisgender man. This …
A Literature Analysis Of Microgrid Optimization Studies, Izzy Medeiros
A Literature Analysis Of Microgrid Optimization Studies, Izzy Medeiros
Honors Theses and Capstones
Senior civil engineering student, Izzy Medeiros, is presenting her honors thesis in the form of a literature analysis. Her research involved investigating existing microgrid studies and where there are current gaps in the knowledge. About 40 publications written within the last 20 years were analyzed for their research goals, optimization objectives, and microgrid design, pointing to where this research is currently lacking. Most real studies were conducted in Asia, as Southeast Asia has island communities that need the reliability of a renewable microgrid during extreme weather events. Photovoltaic panels in combination with wind turbines comprise the most common configuration of …
Modeling And Fault Detection In Dc Side Of Photovoltaic Arrays, Mohd Akram
Modeling And Fault Detection In Dc Side Of Photovoltaic Arrays, Mohd Akram
Electronic Theses and Dissertations
Fault detection in PV systems is a key factor in maintaining the integrity of any PV system. Faults in photovoltaic systems can cause irrevocable damages to the stability of the PV system and substantially decrease the power output generated from the array of PV modules. Among'st the various AC and DC faults in a PV system, the clearance of the AC side faults is achieved by conventional AC protection schemes,the DC side, however , there still exists certain faults which are difficult to detect and clear. This paper deals with the modeling, detection and classification of these types of DC …
Folate Nanoparticle Conjugates, Safwat A. Masood
Folate Nanoparticle Conjugates, Safwat A. Masood
All Capstone Projects
The folate receptor is overexpressed on the surface of numerous cancer cell types including those of the breast, lung, kidney, ovary, and brain. Recent interest has exploded in the use of folate to deliver payloads and imaging agents to folate receptor positive cancer cells based on several positive clinical trials including phase III trials of EC-145, which is poised to become the first folate targeted, FDA approved drug. Given the success of EC-145 and numerous other agents in the pharmaceutical pipeline, there remains a great interest in the exploitation of this technology in the delivery of nanoscale agents to folate …
Design And Construction Of Pavements In Cold Regions: State Of The Practice, Brad Steven Smith
Design And Construction Of Pavements In Cold Regions: State Of The Practice, Brad Steven Smith
Theses and Dissertations
The effects of frost action introduce many challenges in the design and construction of roadways in cold regions throughout the United States. The penetration of frost into pavement structures can lead to differential frost heave during winter and thaw weakening during spring. Both of these damage mechanisms lead to premature pavement distress, structural deterioration, and poor ride quality. Because the availability of naturally occurring non-frost-susceptible pavement base materials is rapidly diminishing in many areas while project budgets remain largely inadequate, pavement engineers are utilizing alternative materials and techniques to minimize such damage. The purpose of this research was to investigate …
