Systems with critical functionality and are prone to damage due to excessive stress level from operation conditions and working environment requires health monitoring. Condition or health monitoring involves acquiring data that can be...
Although many attempts have been made to construct an economically feasible Fault Current Limiter (FCL), no FCL has yet been widely accepted by the power industry. This thesis presents a novel fault current limiter for power system...
Swarm behavior indicates the direct or indirect interactions among relatively simple agents to perform a particular task that is unknown to the individual agent. The study of swarm behavior originates from the research of swarms in...
The semi-autonomous vehicle known as the Experimental Unmanned Vehicle (XUV)was designed by the US Army to autonomously navigate over different types of terrain. The performance of autonomous navigation improves when the vehicle's...
Estimation of a dynamical system under unknown influences is always subjected to uncertainty. Thus, reducing the estimation variance under external influences is absolutely desired and becomes the motivation for the field of System...
This dissertation addresses the development of efficient digital filter implementation techniques. Measures for area, latency, and throughput are used to quantify the benefits of the proposed implementation schemes, as well as...
Common military radar systems transmit sophisticated pulse compression waveforms for range information. Although much progress has been made in suppressing the platform radar cross section to avoid detection by enemy active radar, little...
Shapes of boundaries can play an important role in characterizing objects in images. Shape analysis involves choosing mathematical representations of shapes, deriving tools for quantifying shape differences, and characterizing imaged...
Mines pose a major threat to the fleet. Finding and clearing minefields is an extremely important but difficult task. In response, systems have been produced to scan the sea floor for mines. A tow fish, used in mine countermeasures by...
Robotic tasks call for a range of steering activity: one extreme is highway driving with negligible turning for hundreds of kilometers; another is steering for battlefield robots, which call for agile turning. System modeling and...
The main goal of this master's thesis is to explore and develop centralized and optimization techniques for terrestrial power systems and for heterogeneous systems like a ship's cooling system. First, an agent based decentralized multi...
Modal based traditional Structural Health Monitoring techniques are limited because of several factors – including a poorly-formed aggregate system model, very low SNR, and unrealistic boundary conditions. Moreover, global techniques...
The conditions that arise in the Cocktail Party Problem prevail across many fields creating a need for of Blind Source Separation. The need for BSS has become prevalent in several fields of work. These fields include array processing, ...
Due to their exhibition of nonlinearities, electrical power systems, such as shipboard power systems, provide an interesting research environment. Nonlinear systems are characterized by properties such as highly interdependent components...
Photovoltaic (PV) systems behave in an extraordinary and useful way: they react to light by transforming part of the incoming photons into electricity. Since PV installations require no fuel to operate, produce no pollution while...
A mobile robot has an ability to navigate and perform tasks in unstructured environments like battlefields, farms, earth moving sites, waste clean up sites and exploration. All mobile robots use locomotion that generates traction, ...
Wheeled vehicles typically suffer from kinematic wheel slip when moving over an uneven terrain. This wheel slip can lead to decreased localization ability, higher sensory and computational burdens, uncontrolled motion, and decreased...
The cellular industry came into existence 25 years ago and as of today, there are approximately 150 million subscribers worldwide. The cellular industry generates $30 billion in annual revenues and is one of the fastest growing...
The along-track resolution of a sonar system is proportional to the aperture length in the along-track direction. Synthetic aperture sonar (SAS) coherently sum samples from multiple physical locations to form a synthesized aperture which...
This thesis presents and evaluates a bio-inspired vision system design to increase the depth field of a stereoscopic ranging imager. Two key attributes of the human vision system are leveraged in this design. The first attribute is image...
Filtering is an important aspect of the modern power system. By reducing the effects of harmonics, power transmission and utilization becomes more efficient. This research examines the use of neural networks for the estimation and...
Demand for decentralized, wireless, ad-hoc systems, where hosts are free to leave or join, to replace wired communication systems has seen a phenomenal growth. Such networks need little or no infrastructure support to operate. Deploying...
Gas turbine-synchronous generator (GT-SG) systems are the main source of power and propulsion onboard most naval ships. Since this system plays a vital role in accomplishing the ship's mission, a lot of testing is conducted to ensure...
Bridges in Florida are exposed to high amounts of humidity due to the state's geography. This excess moisture results in a high incidence of corrosion on the bridge's steel support cables. Also, the inclusion of ineffective waterproofing...
The paint and coatings industry is constantly working to improve their product, making a more efficient product at a cheaper cost. This requires some research and learning on the part of the companies, particularly in optical studies....
Detection and estimation of frequencies in composite signal is a very important topic. The resolution issue is the most fundamental. The higher the resolution, the more precise information we can get from the signal. The traditional...
Wavelets are mathematical functions that cut up data into different frequency components, and then study each component with a resolution matched to its scale. Wavelets are an extremely useful tool for coding images and other real...
This paper investigates the stability issues in an islanded microgrid. A microgrid, once disconnected from the main grid, has to entirely depend on the Distributed Generators (DG), which are mostly intermittent renewable sources (e.g. PV...
Individual vehicle information, specially, vehicle classification data play a key role in road traffic measurement. In inductive loop and piezoelectric sensor systems, traffic data such as number of axles and the distance between axles...
Wavelet Transform has been successfully applied in different fields, ranging from pure mathematics to applied sciences. Numerous studies carried out on Wavelet Transform have proven its advantages in image processing and data compression...
