More than 50% of the total energy produced is typically rejected in the form of waste heat from various processes. The grand challenge is that most of this waste heat is released at temperatures much lower than 1000 C, which makes it difficult to...
Accelerated life testing; Reliability (Engineering); Service life (Engineering)
This dissertation is focused on finding lower confidence limits for the reliability of systems consisting of Wei bull components when the reliability demonstration testing (RDT) is conducted with zero failures. The usual methods for the parameter...
A class of RC active filters in which the DC offset of the operational amplifier (op-amp) is completely absent from the filter output [1]. Individual filter configurations (Low Pass, High Pass, Band Pass, Band Stop, All Pass) are discussed and...
An ensemble consists of a set of individual predictors whose predictions are combined. Generally, different classification and regression models tend to work well for different types of data and also, it is usually not know which algorithm will be...
Cardiac mapping has become an important area of research for understanding the mechanisms responsible for cardiac arrhythmias and the associated diseases. Current technologies for measuring electrical potentials on the surface of the heart are...
Swarm Intelligence (SI) techniques were inspired by bee swarms, ant colonies, and most
recently, bird flocks. Flock-based Swarm Intelligence (FSI) has several unique features, namely
decentralized control, collaborative learning, high exploration...
Recently our lab has shown that with broadband stimuli (either visual noise or natural scenes), performance for detecting oriented content is worst at horizontal, best at the obliques, and intermediate at vertical orientations--an anisotropy...
Emergency management--Kentucky; Assistance in emergencies--Kentucky; Disaster relief--Kentucky; Transportation--Planning
Large-scale emergencies caused by earthquake, tornado, pandemic flu, terrorism attacks and so on can wreak havoc to communities. In order to mitigate the impact of the events, emergency stockpiles of food, water, medicine and other materials have...
Given a metric space (K, d), the hyperspace of K is defined by H(K) = {F c K: F is compact, F ≠ 0}. H(K) is itself a metric space under the Hausdorff metric dH. Hyperspaces have been extensively studied by topologists since the 1970's, but the...
The field of graph theory has been indubitably influenced by the study of planar graphs. This thesis, consisting of five chapters, is a historical account of the origins and development of concepts pertaining to planar graphs and their...
I will report the development of a semi-empirical self-consistent and environment-dependent model Hamiltonian, which is intended to treat large systems in the order of 10000 atoms. This covers a range of important physical phenomena that are too...
This cross-sectional, correlational study ( N = 289) explored the relationships among workplace incivility, conflict management styles and their influence on perceived job performance, organizational commitment and turnover intentions. Differences...
This thesis describes 1) the kinetics of vapor phase place exchange reactions on films of gold monolayer protected clusters (Au MPCs) to alter the functionality of the Au MPCs, 2) applications of the reaction for altering chemiresistive sensing...
Characterization of the optical and electrical properties of organic solar cell materials is of prime importance to organic solar cell design. This thesis describes the use of capacitive photocurrent measurements to study the exciton generation and...
Symmetric piezoresistive microcantilever beams have been demonstrated in previous research to be capable of sensing the presence of surrounding gas. This occurs as the damping effect of the gas changes the beam resonance behavior. Device...
Brief Overview of the Problem: The Environmental Protection Agency (EPA), a government funded agency, provides both legislative and judicial powers for emissions monitoring in the United States. The agency crafts laws based on self-made regulations...
Electroactive polymers (EAPs), including conducting polymers (CPs) such as polyaniline (PAn), and hydrogels are exciting areas of research in disciplines such as biomedical engineering, with the goal of creating low-cost, lightweight, non-toxic...
In this dissertation, standardized methods for measuring electron emission (EE) from nanostructured materials are established. Design of an emitter array platform, synthesis and nanomanipulation of different types of are successfully conducted....
This paper explores issues of identity and difference in art and its institutions through a historiographic study of two landmark exhibitions, "The Other Story: Afro-Asian Artists in Post-War Britain" (1989) and the 1993 Whitney Biennial....
High dynamic range imaging involves imaging at a bit depth higher than the typical 8-12 bits offered by standard video equipment. We propose a method of imaging a scene at high dynamic range, 14+ bits, to detect motion correlated with changes in...
