Random Walks on Random Lattices and Their Applications
(2015-05)This work studies a class of continuous-time, multidimensional random walk processes with mutually dependent random step sizes and their exits from hyperrectangles. Fluctuations of the process about the critical boundary ... -
Rapid Generation of 3D Microchannels Using a Multiphoton Laser System in Blended Hydrogels to Serve as Templates for Microvascular Generation
(2016-09)Lack of scaffold microvascularization is one of the biggest problems facing graft survival and success within current tissue engineering applications. Fortunately, techniques aiming to form microchannels within ... -
RapidScat Backscatter Measurements Calibration
(2019-05)Scatterometers are microwave radars deployed to estimate global wind speeds and directions over sea surface by measuring Normalized Radar Cross Section (σᵒ) of the sea. Measured is determined by the sea surface roughness ... -
Re-evaluation of resistance prediction for high-speed round bilge hull forms
(2012-07)Predicting the resistance of a high-speed monohull has been of interest to Naval Architects for several decades. Even though considerable amount of research has been carried out in this area, there remains a degree of ... -
Real Time Implementation of an Inertial Measurement Unit based on Fiber-Bragg Sensor Array using Legendre Polynomial
(2016-12)Missiles and launch vehicle are trending towards becoming more slender in shape to reduce aerodynamic drag. Bending vibrations of the rocket body occur when a flying object with a large slenderness performs pitch or yaw ... -
Real-Time Facial Expression and Speech Emotion Recognition App Development on Mobile Phones using Cloud Computing
(2018-11)Emotion plays a vital role in humans’ daily lives. Understanding emotions and recognizing how to react to others’ feelings are fundamental to engaging in successful social interactions. Emotion recognition through facial ... -
Real-time Monitoring of Sand and Dust Storm Winds Using Wireless Sensor Technology
(2016-09)This dissertation proposes an empirical model for prediction of the radio path loss in Wireless Sensor Networks (WSNs). The model applies to WSNs that are deployed in environments with dust and sand storms. It is developed ... -
A Real-Time Solution Strategy for Estimation of Aerothermal Heating for Reentry Vehicles
(2017-12)Direct measurement of flight environment on a heat shield of a Reusable Launch Vehicle (RLV) is critical due to the extremely aerothermal heating experiences during the reentry phase. An alternative approach is to install ... -
A Recommender System for Improving Program Security Through Source Code Mining and Knowledge Extraction
(2018-07)The security of computer programs and systems is a very critical issue. Threats against computer networks and software are on the rise. Therefore, businesses and IT professionals should take steps to ... -
Reef-Building Threatened by Ecosystem Decline: A Case Study from Buck Island, U.S. Virgin Islands
(2017-05)Coral reefs are critical barriers to coastal erosion and flooding throughout tropical regions, but their role in coastal protection is threatened by declining coral populations and sea-level rise. Climate change is causing ... -
A Reinforcement Learning Approach to Autonomous Speed Control in Robotic Systems
(2017-05)Model-free reinforcement learning techniques have been successfully used in diverse robotic applications. In this thesis, we Implement the Q-learning algorithm as one of the most used model-free algorithms to find an ... -
Relativistic Runaway Electron Avalanches Inside the High Field Regions of Thunderclouds
(2015-05)In this dissertation, simplified equations describing the transport and energy spectrum of runaway electrons are derived from the basic kinematics of the continuity equations. These equations are useful in modeling the ... -
Repeatability of Reference Signal Received Power Measurements in LTE Networks
(2017-05)Reference Signal Received Power (RSRP) reports are routinely used to monitor and benchmark the coverage in LTE cellular networks of fourth generation. Such measurements also trigger idle and active mode mobility decisions ... -
Residence Time Distribution (RTD) Analysis of a Bioreactor's External Recirculation Loop for a Tissue Engineering Test Bed
(2019-05)Currently, in tissue engineering, the focus is on morphing cells into a particular type of tissue by hand, rather than automating the process. Automating cell feeding and waste removal, alone,still requires the removal ... -
Resistance prediction for asymmetrical configurations of high-speed catamaran hull forms
(2015-12)Predicting the resistance of a high-speed catamaran has been of interest to naval architects for the last three decades. Even though considerable amount of research has been carried out in this area, there remains a degree ... -
Resonant Coupling of an Infrared Metasurface with PMMA
(2014-05)Resonance coupling between a metasurface or planar metamaterial and PMMA’s, polymethyl methacrylate, phonon resonance corresponding to the C=O molecular bond at 1733 cm-1 (52 THz) is investigated. Two metasurfaces, nano ... -
Reverberation Mapping of the Dusty Torus in Active Galactic Nuclei
(2016-04)The Dusty Torus is a structure that is believed to exist in Active Galactic Nuclei. The Torus is physically too small to be spatially resolved, so Reverberation Mapping can be performed in order to replace spatial ... -
A Review of the Potential Therapeutic Application of Vagus Nerve Stimulation During Childbirth
(2017-03)The goal of this research is to show that transcutaneous Vagus nerve stimulation (tVNS) should be investigated as a possible modality for increasing endogenous release of oxytocin during childbirth. There have been many ... -
A Robot FDM Platform for Multi-Plane and 3D Lattice Structure Printing
(2018-06)Additive manufacturing is a process to fabricate three-dimensional (3D) objects usually by joining a material layer by layer. The layer by layer joining process simplifies the fabrication method by slicing the 3D object ...
