Relaxation of Variational Principles for Z-problems in Effective Media Theory
(2022-05)In this thesis, we consider a class of Z-problems and their associated effective operators on Hilbert spaces which arise in effective media theory, especially within the theory of composites. We provide a unified approach ... -
The Development of a New All-in-one Allsky Camera and Radiometer System
(2022-05)We developed a new all-in-one camera and radiometer system for meteor surveillance. It proved successful during its first bolide event on 13 April 2021, as reported in the journal Meteoritics and Planetary Science, volume ... -
Smart Glasses Assisting Visually-Impaired People
(2021-12)Smart Glasses Assisting Visually-Impaired artificial intelligence system providing speech recognition, object recognition, face recognition, and distance to all features for visually impaired people's enhanced (daily) ... -
Feasibility Analysis and Performance Study of a Pulsed Solid Propellant Integrated Propulsion System for Small Satellites
(2021-12)Solid propellant has come a long way since the 13th century when gunpowder was widely used as the go-to means in rocket propulsion. Of course, back then, rockets were not intended to carry humanity out of the atmosphere. ... -
3D Printed Bioglass Incorporated Collagen Matrices for Musculoskeletal Tissue Engineering
(2021-12)Musculoskeletal injuries are a major cause of disability affecting millions of people around the world and resulting in a significant economic burden of over $14 billion. Surgical intervention using autografts and ... -
Development and Optimization of a Denitrification System to Promote Biological Nutrient Removal in a Subtropical Estuary
(2021-12)Eutrophication impacts coastal ecosystems globally and triggers phytoplankton and algal blooms, leading to an increase in oxygen demand in the water column and sediments due to various biogeochemical processes. Naturally, ... -
An Assessment of Image-Cloaking Techniques Against Automated Face Recognition for Biometric Privacy
(2021-12)Over the past two decades, Americans have aggressively increased the amount of facial data uploaded to the internet primarily via social media. This data is largely unprotected due to the dire lack of existing regulations ... -
A Machine Learning-Based Approach to Predict and Optimize the Performance of Zero Energy Building (ZEB): A Case Study for Florida
(2021-12)Machine learning is currently one of the most searched fields aiming to solve real-life problems. Building simulation software tools help engineers estimate building energy behaviors before the actual construction, ... -
Autonomous Feature Detection for Capture Path Planning for Rendezvous and Docking with Non-Cooperative Spacecraft
(2021-12)With the increasing risk of collisions with space debris and the growing interest in on-orbit servicing, the ability to autonomously capture non-cooperative, tumbling target objects remains an unresolved challenge. This ... -
Application of Ensemble Methods for Solving Offshore Wind Farm Layout Optimization Problems
(2021-12)Wind energy is considered as one of the most promising renewable energy sources. The intent of this dissertation is to assess the application of ensemble methods on offshore wind farm layout optimization. In this regard, ... -
A Comparative Study on the Application of Intelligent Algorithms as the Solution of Inverse Heat Conduction Problems
(2021-12)A critical component necessary for the safety and survival of space vehicles are the thermal protection systems (TPS). Especially when subject to atmospheric re-entry, the heating loads subject to the space vehicle requires ... -
Forecasting SEP Events based on Merged CME Catalogs using Machine Learning
(2021-12)The lack of preparation for a Solar Energetic Particle (SEP) event may be catastrophic for astronauts and aircraft passengers alike, along with their electronic equipment. It is widely theorized that SEP events are caused ... -
Flow Choice Architecture: Cognitive Augmentation of Knowledge Workers
(2021-12)The Flow Choice Architecture (FCA) is a biofeedback-based behavior modification tool that was designed for operation by human knowledge workers (KWs) before, during, and after the performance of work tasks. FCA utilizes ... -
Crashworthiness of Metallic Tubes Under Off-Axial Loading
(2021-12)Energy absorbing structures (EAS) are structures used to make the frame of a vehicle absorb energy during an impact scenario and keep the deceleration forces within survivable limits for the occupant(s). These structures ... -
Helicopter Flight Energy Modeling and Scaling for Urban Air Mobility Applications
(2021-12)The costs associated with conducting full-scale helicopter flight tests in terms of both time and money beg to question the validity of using small-scale model helicopters in order to predict full-scale performance. To do ... -
Flight Test Evaluation of Elevator Stick Force Gradients on General Aviation Aircraft
(2021-12)The objective of this research is to establish a suitable method of changing elevator stick force gradients on a Piper Warrior II. After finding a range of stick force gradients, the gradients will later be evaluated to ... -
On a class of critical N-Laplacian problems
(2021-12)We establish some existence results for a class of critical N-Laplacian problems in a bounded domain in RN. In the absence of a suitable direct sum decomposition, we use an abstract linking theorem based on the ... -
The Effects of a Flipped Classroom Compared to a Traditional Classroom on Students’ Mathematics Achievement and Critical Thinking Skills at Benghazi University
(2021-12)This study aimed to compare the effects of two different instructional models (flipped and traditional) on students’ mathematics achievement and critical thinking skills (CTS) at Benghazi University. This study used a ... -
Intermittency Scaling Laws in Magnetohydrodynamic Turbulence: Theory, Simulations and Observations
(2021-10)The main objective of this dissertation is to investigate intermittency of Magnetohydrodynamic (MHD) plasmas by means of high-resolution numerical simulations and large sets of solar wind data. Understanding intermittency ... -
Variations in Otolith-Zinc Concentrations of Brown Surgeonfish (Acanthurus nigrofuscus) Between Marine Protected Areas and Fished Reefs
(2021-12)As human populations continue to increase, the growing reliance on exploited fish stocks has furthered patterns of declining body size and biomass worldwide. To mitigate these impacts, fisheries managers have implemented ...
