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...
Background: Emerging circulatory support devices that operate in counterpulsation to the native heart require synchronized timing of device ejection and filling on a beat-to-beat basis with the native heart using a patient's ECG. Surface leads are...
In some previous papers, feed forward configurations of realizing second order all pass transfer functions with complex poles by adding some configurations to a first order circuit are discussed. In this dissertation, the above idea extended to...
This thesis will focus on the topic of Selfish Nodes within a Mobile Ad-Hoc Networks (MANET), specifically sensor networks due to their lower power and bandwidth. The approach used is a reputation based algorithm to isolate the selfish nodes from...
In a nonlocally compact Polish abelian group G, we will consider two notions of smallness of subsets of G. Those subsets of G which are topologically small are said to be meager, and those which are measure-theoretically small are Haar null. We...
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...
Historically in the area of pediatric heart failure, few options have been available that are specifically designed to provide pediatric circulatory support. Extracorporeal Membrane Oxygenation (ECMO) was the traditional method of choice, providing...
Premenopausal women have fewer and less severe strokes when compared to postmenopausal females and aged matched males. The most obvious factor that could account for the observed difference is the physiological activity of Estrogen. Numerous...
Computer-aided minimally invasive surgery (MIS) has progressed significantly in the last decade and it has great potential in surgical planning and operations. To limit the damage to nearby healthy tissue, accurate modeling is required of the...
Many important applications require the discovery of items which have occurred frequently. Knowledge of these items is commonly used in anomaly detection and network monitoring tasks. Effective solutions for this problem focus mainly on reducing...
Mathematical imaging consists of many different applications including image segmentation, image classification, and inpainting. This work deals more specifically with image segmentation: the partition of an image into the background and the...
This dissertation presents an analytical investigation that examined the seismic performance of steel stud backed and Concrete Masonry Units (CMU) backed masonry veneer wall systems, under in and out - of - plane loads, in medium rise building...
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...
In July 1995, National Science Foundation Award # 9551869 funded the development of a new inter-disciplinary microfabrication course under the primary leadership of Dr. Kevin Walsh at the University of Louisville. Along with this award, the...
The Technical Advisory Group (TAG) of the Innovative Treatment Remediation Demonstration Program (ITRD) made technology recommendations after reviewing thirty in situ remediation technologies for implementation at the Paducah Gaseous Diffusion...
The Combinatorial Nullstellensatz can be used to solve certain problems in combinatorics. However, one of the major complications in using the Combinatorial Nullstellensatz is ensuring that there exists a nonzero monomial. This dissertation looks...
Blood flow--Measurement; Magnetic resonance imaging
Peripheral Arterial Disease (PAD) is a progressive atherosclerotic disorder which
is defined as any pathologic process obstructing the blood flow of the arteries supplying
the lower extremities. Moderate stenoses mayor may not be...
The purpose of this research study is to examine the use of time series forecasting and text mining to investigate the prescription of antibiotics. The specific objective is to examine the relationship between the total payments, private insurance...
Cheating (Education); Web-based instruction; College students--Attitudes
This dissertation examined cheating attitudes and behaviors of undergraduates, especially those enrolled in online courses. While cheating is an established problem within the academy, it is also an issue on the job and has been in the spotlight in...
Understanding of the band structure of the new nano materials is essential to have a deeper insight into their optical and electrical properties. Along with the existing techniques used for characterization of nano-materials, it is also important...
