A Quasi-Resonant Bidirectional Converter with Soft-Switching Operation for Energy Storage Applications
(2018-08-27)The increased penetration of renewable energy power systems to produce clean and sustainable energy has led to the increased usage of various types of energy storage devices, such as high power density battery technologies, ... -
An Empirical Assessment on the Techniques Used in Load Testing
(2017-07-27)There are two main problems associated with load testing research: (1) the testing environment might not be realistic and (2) lack of empirical research. To address the first problem, we systematically assess the performance ... -
Applications of Utility-Scale Power to Gas Energy Storage Systems in Smart Grids
(2019-03-05)ABSTRACT This thesis aims to develop the engineering tools required to simulate, design, and optimize the operation of utility-scale power to gas (PtG) energy storage. First, a co-simulation platform for power and gas ... -
Attention and Sensor Planning in Autonomous Robotic Visual Search
(2015-08-28)This thesis is concerned with the incorporation of saliency in visual search and the development of sensor planning strategies for visual search. The saliency model is a mixture of two schemes that extracts visual clues ... -
Automatic Speed Control For Navigation in 3D Virtual Environment
(2016-11-25)As technology progresses, the scale and complexity of 3D virtual environments can also increase proportionally. This leads to multiscale virtual environments, which are environments that contain groups of objects with ... -
Autonomous Trail Following
(2018-05-28)Trails typically lack standard markers that characterize roadways. Nevertheless, trails are useful for off-road navigation. Here, trail following problem is approached by identifying the deviation of the robot from the ... -
Characterizing and Improving Logging Practices in Java-based Open Source Software Projects - A Large-scale Case Study in Apache Software Foundation
(2017-07-27)Log messages (generated by logging code) contain rich information about the runtime behavior of software systems. Although more logging code can provide more context of the system's behavior, it is undesirable to include ... -
Compressive Sensing and Time Reversal Beamforming Approaches for Ultrasound Imaging
(2015-12-16)The objective of this thesis is to develop a novel beamforming technique for ultrasound machines that enables field reconstruction at sampling rates much lower than the Nyquist rate. In our simulations, we use Field II, a ... -
Coordinated Sensor-Based Area Coverage and Cooperative Localization of a Heterogeneous Fleet of Autonomous Surface Vessels (ASVs)
(2015-08-28)Sensor coverage with fleets of robots is a complex task requiring solutions to localization, communication, navigation and basic sensor coverage. Sensor coverage of large areas is a problem that occurs in a variety of ... -
Distributed State Estimation For Smarter Electric Power Grids
(2015-08-28)The focus of this thesis is to design and implement distributed and decentralized state estimation (SE) algorithms for smart Electric Power Grids (EPGs). These algorithms are applied to two different types of EPGs: 1) ... -
Does Motion Matter?: Comparing Locomotion Interfaces in Virtual Environments Using Presence in Decision-Making Tasks
(2021-03-08)Virtual environments can replicate the appearance of terrain, but walking interfaces can confer sensations in other modalities incongruent with the visual presentation, and might therefore affect navigation decisions. I ... -
Embedded CMOS Basecalling for Nanopore DNA Sequencing
(2017-07-27)DNA sequencing is undergoing a profound evolution into a mobile technology. Unfortunately the effort needed to process the data emerging from this new sequencing technology requires a compute power only available to ... -
Factors for Interactive Liquid Perception in Augmented Reality on Mobile Devices
(2019-07-02)Augmented reality (AR) is one of the hottest things with Apple and Google trying to capture people\textquotesingle s interests and wonder. Given these new needs, there have not been much on what the best thing to do when ... -
Implementation Of A Novel Cooperative Protocol for Distributed Voltage Control in Active Distribution Networks
(2018-08-27)Microgrids are small localized grids that help to integrate many renewable-energy sources into the main electric grid. Microgrids can also operate separately from the main electric grid during faults to enhance the customers ... -
Nonnegative Code Division Multiple Access Techniques in Molecular Communication
(2017-07-27)In molecular communication, two types of multiple access have been studied: time division and molecule division. In this work, we consider code division multiple access. However, unlike code division multiple access that ... -
Operation of Over-Current Relays During Double-Phase Operation Mode of Power Distribution Systems
(2018-11-21)Power system reliability is one of the objectives of every electric utility. Statistical analyses of faults in power systems demonstrate that most of the faults are asymmetrical, most commonly, single-phase to ground. ... -
Performance Analysis of Coexistence Schemes for LTE in Unlicensed Bands
(2017-07-27)LTE in the unlicensed spectrum, is becoming a popular area of research. Since LTE-Unlicensed (LTE-U) provides subscribers with higher-quality mobile voice, and video experience in high-traffic or low-signal locations, a ... -
