Empirical Analysis Of Software Reliability, Margaret L. Hamill Jan 2006

Empirical Analysis Of Software Reliability, Margaret L. Hamill

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis presents an empirical study of architecture-based software reliability based on large real case studies. It undoubtedly demonstrates the value of using open source software to empirically study software reliability. The major goal is to empirically analyze the applicability, adequacy and accuracy of architecture-based software reliability models. In both our studies we found evidence that the number of failures due to faults in more than one component is not insignificant. Consequently, existing models that make such simplifying assumptions must be improved to account for this phenomenon. This thesis' contributions include developing automatic methods for efficient extraction of necessary data …

Predicting Inflation, And The Relationship Between Financial Integration, Financial *Development And Economic *Growth, Lillian T. Kamal Jan 2006

Predicting Inflation, And The Relationship Between Financial Integration, Financial *Development And Economic *Growth, Lillian T. Kamal

Graduate Theses, Dissertations, and Problem Reports (ETD)

Three essays are presented. The first essay re-visits the P* model (developed by Hallman, Porter and Small, 1991) with an application to US data. The central idea behind the P* model is that the price level is determined by the money stock, output and velocity. This study brings together criticisms of the P* model together in an attempt to address the major concerns with an improvement upon the existing model. A horse race is then run between the original P* model, two variant P* models, and three other models---an atheoretic naive AR process and an ARMA process as well as …

Enlightened Defense: The National Security *Policy Of Thomas Jefferson, Robert R. Leonhard Jan 2006

Enlightened Defense: The National Security *Policy Of Thomas Jefferson, Robert R. Leonhard

Graduate Theses, Dissertations, and Problem Reports (ETD)

The triumph of Thomas Jefferson and the Democratic Republicans in 1800 left the deposed Federalists aghast at what this Francophile, anti nationalist, reputedly atheistic president might do to the country. Despite Jefferson's impulses toward pacifism, national isolation, the diffusion of political power, and healing faction, the eight years of his two administrations were destined to be as calm as a hurricane. The turbulent situation in Europe had already made a mockery of Washington's advice to avoid entanglement, and during Jefferson's presidency, the dangers only increased.;Jefferson's ideas on national security were diametrically opposed to those of Alexander Hamilton and the Federalists. …

Transactional Distance And Student Motivation: Student Perception Of Teacher Immediacy, Solidarity Toward Peer Students And Student Motivation In Distance Education, Hye Yoon Jung Jan 2006

Transactional Distance And Student Motivation: Student Perception Of Teacher Immediacy, Solidarity Toward Peer Students And Student Motivation In Distance Education, Hye Yoon Jung

Graduate Theses, Dissertations, and Problem Reports (ETD)

Transactional Distance Theory is conceptually significant in that the core nature of distance in distance education is not a geographical or temporal distance but a psychological or communicational distance between students and their teacher(s), as well as among students. In spite of the conceptual significance of the transactional distance theory, the interrelationships among the construct variables and propositions of the theory are unclear. The majority of studies on transactional distance theory either used the theory solely as a conceptual framework, or proposed the refinement of the theory. Literature review indicated that the theory was found to be invalid and unreliable. …

Classification Of Dental X-Ray Images, Usman Qureshi Jan 2006

Classification Of Dental X-Ray Images, Usman Qureshi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Forensic dentistry is concerned with identifying people based on their dental records. Forensic specialists have a large number of cases to investigate and hence, it has become important to automate forensic identification systems. The radiographs acquired after a person is deceased are called the Post-mortem (PM) radiographs, and the radiographs acquired while the person is alive are called the Ante-mortem (AM) radiographs. Dental biometrics automatically analyzes dental radiographs to identify the deceased individuals. While, ante mortem (AM) identification is usually possible through comparison of many biometric identifiers, postmortem (PM) identification is impossible using behavioral biometrics (e.g. speech, gait). Moreover, under …

Lossless Compression Of Hyperspectral Images, Sushil Kamalchand Jain Jan 2006

Lossless Compression Of Hyperspectral Images, Sushil Kamalchand Jain

Graduate Theses, Dissertations, and Problem Reports (ETD)

Band ordering and the prediction scheme are the two major aspects of hyperspectral imaging which have been studied to improve the performance of the compression system. In the prediction module, we propose spatio-spectral prediction methods. Two non-linear spectral prediction methods have been proposed in this thesis. NPHI (Non-linear Prediction for Hyperspectral Images) is based on a band look-ahead technique wherein a reference band is included in the prediction of pixels in the current band. The prediction technique estimates the variation between the contexts of the two bands to modify the weights computed in the reference band to predict the pixels …

Signaling Pathways Involved In Regulation Of Glucose -6 -Phosphate Dehydrogenase (G6pd) By Arachidonic Acid, Indrani Talukdar Jan 2006

Signaling Pathways Involved In Regulation Of Glucose -6 -Phosphate Dehydrogenase (G6pd) By Arachidonic Acid, Indrani Talukdar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Glucose-6-phosphate dehydrogenase (G6PD) is the rate-limiting enzyme of pentose phosphate pathway and provides NADPH for de novo fatty acid biosynthesis. For the later reason, G6PD is known as a lipogenic enzyme. Insulin induces expression of G6PD mRNA via activating the PI3 kinase pathway in primary rat hepatocytes. Addition of arachidonic acid, a polyunsaturated fatty acid, in the medium interferes with the PI3 kinase pathway, and thus inhibits the insulin-mediated induction of G6PD. Arachidonic acid in the presence of insulin induces p38 MAP kinase pathway over insulin treatment alone. Activation of p38 MAP kinase by arachidonic acid interferes with the insulin …

Post-Implant Dosimetry Analysis Of Brachytherapy Patients Using Pre And Post-Implant Mri, Deana Lee Tuttle Jan 2006

Post-Implant Dosimetry Analysis Of Brachytherapy Patients Using Pre And Post-Implant Mri, Deana Lee Tuttle

UNLV Retrospective Theses & Dissertations

Post-implant dosimetry analysis is a critical step in brachytherapy for identifying the quality of the implant based on seed localization in relation to the volume of the prostate. However, the accuracy of post-implant dosimetry analysis is dependent on accurate delineation of the prostate from surrounding tissue in post-implant CT images. Research has shown that adequately delineate the prostate from surrounding tissue in CT images is difficult, resulting in significant variation between the dose received by the prostate and the dose prescribed by the physician. This research compared prostate volumes delineated from pre-implant US, post-implant CT, and pre and post-implant MR …
