A common research interest in medical, biological, and engineering research is determining whether certain independent variables are correlated with the survival or failure times. Standard statistical techniques cannot usually be applied for...
A connected matching in a graph is a set of disjoint edges such that, for any pair of these edges, there is another edge of the graph incident to both of them. This dissertation investigates two problems related to finding large connected matchings...
New products--Management; Consumer satisfaction; Marketing--Management
A constant flow of innovative products which meets the needs of customers and therefore is a monetary success for the inventing organization is important for the long term success of organizations, especially in modem dynamic markets. As resources...
A decision support system (DSS) is a computer-based tool that extends an operator's cognitive abilities and makes him more effective in decision-making situations. This thesis discusses the characteristics and historical applications of decision...
A hyper basis function network (HyperBF) is a generalized radial basis function network (RBF) where the activation function is a radial function of a weighted distance. The local weighting of the distance accounts for the variation in local scaling...
Web search engines; Automatic abstracting; Graph theory--Data processing
After a user types in a search query on a major search engine, they are presented with a number of search results. Each search result is made up of a title, brief text summary and a URL. It is then the user's job to select documents for...
Computational grids are some of the largest computer systems in existence today. Unfortunately they are also, in many cases, the least reliable. This research examines the use of redundancy with permutation as a method of improving reliability in...
Digital images have primarily been viewed using desktop applications. These types of programs attempt to load all of an image's graphical data into memory in order to display the image in its entirety. The method is effective for images that are...
Elastomer degradation when exposed to chloraminated potable water is dependent on a number of poorly understood factors. Temperature and chloramine concentration are both believed to play roles, however, they have not been adequately defined. In...
Intelligent transportation systems; Air quality; Air--Pollution
Environmental or air quality impacts of Intelligent Transportation Systems (ITS)
are very difficult to measure. Some researchers have attempted to quantify the effects of
individual ITS application on emissions; yet, the effects of ITS as a whole...
Estimating and analysis of deformation, either rigid or non-rigid, is an active area of research in various medical imaging and computer vision applications. Its importance stems from the inherent inter- and intra-variability in biological and...
Fiber-reinforced polymer matrix composites (PMCs) using high-temperature thermoplastics as the matrix material represent a lightweight design solution for applications above 250°F. This is often required for aircraft structures subjected to...
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...
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...
Gold nanoparticles (AuNPs) have attracted enormous attention in the field of nanotechnology for applications such as, immunoassay, drug delivery, contrast enhancement and tumor therapy. The typical range of gold nanoparticles varies from 1– 150...
Human-computer interaction; Computer vision; Human-machine systems; Nonverbal communication
Hand gesture recognition (HGR) is an important research topic because some
situations require silent communication with sign languages. Computational HGR
systems assist silent communication, and help people learn a sign language.
In this thesis. a...
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...
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...
In order to study the movements of autonomous mobile robots, a tool is needed to quantify those movements. A testbed is an apparatus that provides a designated space for multiple mobile robots while tracking their position in real-time. That...
In recent years, a number of computational and statistical problems for identifying SNP-SNP interactions in high dimensional survival data have been studied, and several data mining approaches have been proposed. However, the relative performance...
