Urbanization disrupts natural soil profiles and as watersheds are
urbanized, their surfaces become impervious and this will result in
reduction of infiltration. For this reason, many cities are facing problems
with treating runoff water. Best...
Pattern perception--Data processing; Pattern recognition systems; Land mines--Detection; Data mining
For complex detection and classification problems, involving data with large intra-class variations and noisy inputs, no single source of information can provide a satisfactory solution. As a result, combination of multiple classifiers is playing...
This dissertation describes new procedures for synthesizing and purifying Au and Au/Ag nanoplates directly on surfaces as well as controlled binding of proteins to their surface. It also describes fundamental changes in the optical properties of Au...
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...
For complex classification systems, data is usually gathered from multiple sources of information that have varying degree of reliability. In fact, assuming that the different sources have the same relevance in describing all the data might lead to...
The research in this dissertation describes a simple electrochemical approach for fabricating nanoscale (metal/metal) or molecular (metal/polymer or self assembled monolayer (SAM)/metal) junctions. The fabrication involves metal deposition on one...
While housing tenure choice by the general population and minorities has been studied by a good number of researchers, current research on the tenure choice by immigrants has been limited and sporadic. This study provides further understanding of...
This dissertation describes (1) size-dependent electrochemical oxidation/stripping of gold and silver nanoparticles (NPs), (2) alloying of copper with gold nanoparticles at underpotential deposition potentials, (3) electrochemical characterization...
Image processing; Computer vision; Pattern recognition systems
Image segmentation is one of the most important problems in image processing, object recognition, computer vision, medical imaging, etc. In general, the objective of the segmentation is to partition the image into the meaningful areas using the...
Implementing Job Rotation as a manufacturing method is beneficial to production efficiency, reduction of labor cost, operator satisfaction, and Work-related Musculoskeletal Disorders (WMSDs) reduction. In this thesis, the steps of simulating the...
Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different...
New firms face financial constraints that could hinder firm performance. Yet founders exhibit persistence and resourcefulness in building their new ventures and finding solutions to their financial constraints. The use of financial theories that...
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...
English language--Study and teaching--Foreign speakers--Case studies; English language--Study and teaching--Kentucky--Louisville
This thesis examined the structure and processes of several different organizations that offer English as a Second Language (ESL) classes in one Kentucky county. The purpose of the study was to analyze the structure of the organizations, and then...
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...
Nanomaterials have many intriguing applications in biology and medicine. Unique properties such as enhanced electrical properties, increased chemical reactivity and resistance to degradation, novel optical properties and comparable size to that of...
This work presents a novel comprehensive effort to understand the fluid dynamics within orbiting dishes and the effects of the resulting oscillating fluid flow on shear and endothelial cellular responses within the dishes. It is well documented...
Various vision tasks are usually confronted by appearance variations due to changes of illumination. For instance, in a recognition system, it has been shown that the variability in human face appearance is owed to changes to lighting conditions...
In the 1990s, especially the years before and after Hong Kong's return to the People's Republic of China in 1997, some celebrated and talented Hong Kong film stars, such as Jackie Chan, Yun-Fat Chow and Michelle Yeoh, sought their career success in...
