The use of Ground-penetrating Radar (GPR) for geological exploration, among others, is gaining widespread acceptance. The estimation of electrical parameters (permittivity) from data collected using a Ground Penetrating Radar (GPR), also called Electromagnetic Inversion (EM) Inversion, is of immense importance for applications such as sub-surface(More)
The demand for high power high frequency semiconductor devices has led to the development of microwave power devices using GaN and SiC. AlGaN/GaN HEMTs have shown power densities of 9.8 W/mm at 8 GHz. Although these results are very encouraging, significant work needs to be done to improve performance. It is generally recognized that trapping effects limit(More)
A total of 1000 serum samples were obtained from small ruminants in Maiduguri, Borno state, Nigeria and tested for the presence of antibodies against caprine arthritis-encephalitis virus (CAEV) using enzyme-linked immunosorbent assay (ELISA) based on p17 and p28 recombinant GAG proteins. The distribution of the sera tested was as follows: 900 serum samples(More)
We present the design, implementation, and evaluation of a prototype robust textual chat application to be utilized in dynamic distributed environments such as the Multi-Sensor Command and Control Constellation (MC2C). The MC2C environment consists of a set of airborne and ground sites, each of which contains a cluster of clients. Intra-site communication(More)
Srikanth, Hema. Value-Driven System Level Test Case Prioritization (Under the direction of Dr. Laurie A. Williams) Software testing is an expensive process often consuming at least 50% of the total development cost. Among the types of testing, system testing is the most expensive and complex as it involves configuring multiple complete integrated systems to(More)
Ontology is created based on information provided by domain experts and forms the basis for creating metadata. XML, RDF and OWL are some of the languages which are used to represent ontology. The need for knowledge preservation and representation, ontology construction methodology are briefly described. Available tools for ontology development are listed.(More)
In this paper we deal with the Nonlinear Coupled Ordinary Differential Equations(Nonlinear CODE). A Multipoint Boundary Value Problem(MBVP) associated with these Nonlinear Equations is defined as an Operator Equation. This equation(infinite dimensional) is reduced to an Equivalent Bifurcation Equation(finite dimensional) using Schauder’s Fixed Point(More)
ii ACKNOWLEDGEMENTS " In God we Trust! The rest need empirical evidence. " Completing this dissertation has been a challenge and it would have been impossible to complete it without the guidance of some people. I would like to thank Bhagawan Shri Sathya Sai Baba for showering HIS grace on me, my parents and my family and for being patient with me, my(More)
Devices to generate on-demand non-local spin entangled electron pairs have potential application as solid-state analogues of the entangled photon sources used in quantum optics. Recently, Andreev entanglers that use two quantum dots as filters to adiabatically split and separate the quasi-particles of Cooper pairs have shown efficient splitting through(More)
