Fourier transforms form an integral part of most signal processing applications and are therefore a crucial enabler of modern technology. Thus, fast and efficient algorithms to compute the Fourier transform is an area of active research....
The Heisenberg Uncertainty principle is a fundamental concept from Quantum Mechanics that also describes the Fourier Transform. Unfortunately, it does not directly apply to the digital signals. However, it can be generalized if we use...
The innovation and accessibility of Internet across the globe has made life easy. For instance, enormous information in the form of digital data (images, audios, videos, pdf, etc.) is available on Internet, which can easily be accessed...
This document reviews the fault tolerant control (FTC) problems, approaches, and ideas. Chapter one provides the motivation of the need for an FTC, then an overview of the FTC systems and basic terminologies are provided defining faults, ...
Facial expression recognition (FER) is a promising but challenging area of computer vision (CV).Many researchers have devoted significant resources to exploring FER in recent years, but an impediment remains: classifiers perform well on...
Modern CPS are constructed by seamlessly integrating physical devices, computer systems, and communication networks, enabling data exchange and control of physical processes. The networked and distributed integration of computer systems...
Power system designers have more creative flexibility than ever before due to improvements in power electronics technology. The invention of the silicon (Si) insulated gate bipolar transistor (IGBT) in the 1980s was a major improvement...
Switching-mode single-phase DC-AC converters have been widely used in critical applications such as uninterrupted power supply systems and AC motor drivers. Among various control techniques, Pulse Width Modulation (PWM) technique is the...
As land-based robotic missions to Mars have increased in scope and mobility, NASA has intensified its research efforts involving the mechanisms of electrostatic charging on the surface of Mars. The primary concern is that electrostatic...
This study addresses the challenge of achieving a stable teleoperation over the Internet, improving the convergence rate in the presence of high communication time delays, and maintaining consensus in the platoon while the lead agent is...
The CS technology has attracted considerable attention because it can surpass the traditional limit of Nyquist sampling theory. Rather than sampling a signal at a high frequency and then compressing it, the CS senses the target signal in...
Distributed and renewable energy generation (DG) offers great potential in meeting future global energy requirements. Distributed generation consists of small to medium size generators cited close to the customer and spread across a...
Recent years have seen developments in lithium-ion capacitor (LIC) technology. However, there has been scant work in mathematical models to predict the performance of LICs. Existing models have focused upon cell degradation over time or...
In recent years there has been increasing research on incorporating intelligent driver assistance systems (IDAS) into vehicular platforms to help drivers make better driving decisions and to make the roadways safer. The percentage of...
The ability to quantify device performance characteristics is a concern shared by developers, manufacturers, and consumers alike. From a subatomic perspective, the fluctuations found in repeated measurements can be attributed to the...
With the recent advances in the field of Machine Learning, there have been several developments in modern power systems computations. Meanwhile, causality has also received a lot of recognition in various fields such as economics, social...
Switching-mode single-phase DC-AC inverters have been widely used in many applications such as AC motor drivers and uninterrupted power supply systems. Among various control techniques, pulse-width-modulation (PWM) is the most effective...
Computer vision is a field of deep learning that aims to help a computer interpret and visualize the real world. With computer vision evolving as an indispensable development in the field of machine learning, it is being increasingly...
The ability of animals to traverse arboreal structures is uncanny and breath-taking. A simple google search of "animals climbing trees" will display video captured of adult brown bears bounding at jaw-dropping and fear-inducing speeds up...
Dynamic robots require robust controllers to successfully plan and navigate the unstructured world around us. Novel control methods become necessary when these robots' environments are dynamic and the robots themselves have fast and...
Power hardware-in-the-loop (PHIL) simulation is a technique whereby actual power hardware is interfaced to a virtual surrounding system through PHIL interfaces making use of power amplifiers and/or actuators. PHIL simulation is often an...
Computer vision tasks are used in a myriad of applications such as facial and emotion recognition, autonomous driving, visual search, and augmented and virtual reality including virtual tours. In virtual tours, an object detection model...
This dissertation presents an in-depth analysis of using heterogeneous computing to improve the performance of AI algorithms and scientific simulations. This study focuses on two critical project approaches: 1) novel approaches in...
We present novel measurements and analysis of bio-inspired swimming and climbing gaits for long slender organisms and robots. Analysis and experimental results for a lamprey-inspired wall climbing gait. We present this gait on the wall...
