Covert Communications in the RF Band of Primary Wireless Networks
(University of Kansas, 2017-05-31)Covert systems are designed to operate at a low probability of detection (LPD) in order to provide system protection at the physical layer level. The classical approach to covert communications aims at hiding the covert ... -
Determining Cellular and Molecular Mechanisms of Multivalent Soluble Antigen Arrays that Contribute to Therapeutic Efficacy Against a Murine Model of Multiple Sclerosis
(University of Kansas, 2016-12-31)A pressing need exists for antigen-specific immunotherapies (ASIT) that induce selective tolerance in autoimmune disease while avoiding deleterious global immunosuppression. Multivalent soluble antigen arrays (SAgAPLP:LABL), ... -
Adaptive High-Order Discretization of the Reynolds-Averaged Navier-Stokes(RANS) Equations
(University of Kansas, 2016-12-31)The use of high-order methods to compute turbulent flows governed by the Reynolds- averaged Navier-Stokes (RANS) equations is an active research topic in the compu- tational fluid dynamics (CFD) community. However, it is ... -
Large-eddy simulations of turbulent flows using the high-order FR/CPR method
(University of Kansas, 2016-12-31)Large eddy simulation (LES) was originally proposed for simulating atmospheric flows and then has become one of the most successful methodologies for turbulence simulation for its good balance between accuracy and cost. ... -
A Semantics for Attestation Protocols using Session Types in Coq
(University of Kansas, 2016-12-31)As our world becomes more connected, the average person must place more trust in cloud systems for everyday transactions. We rely on banks and credit card services to protect our money, hospitals to conceal and selectively ... -
Investigation of More Complete Constitutive Theories for Heat Conduction in Solids and for Deviatoric Stress Tensor in Incompressible Fluids
(University of Kansas, 2016-12-31)This thesis presents numerical studies utilizing more complete constitutive theories for: (i) Heat vector in isotropic, homogeneous, incompressible, elastic solid continua and (ii) Deviatoric stress tensor for isotropic, ... -
The Design Space Exploration and Preliminary Testing of a New Class of Tailsitting Quadrotor Aircraft
(University of Kansas, 2016-12-31)Within the last decade, multi-rotor aircraft have become the most prevalent form of unmanned aerial vehicle (UAV), with applications in the military, commercial, and civilian sectors. This is due primarily to advances in ... -
KU Steam Power Plant Heat Recovery Component Energy Savings and Evaluation of Pumping System Power Consumption
(University of Kansas, 2016-12-31)Heat recovery is an essential process in any steam power plant because large amounts of energy are lost during the process of generating steam, whether with vented steam or drained hot water. So heat exchangers are used, ... -
Performance and Emissions Analysis of Pre-mixed and Partially Pre-mixed Charge Compression Ignition Combustion.
(University of Kansas, 2017-05-31)Due to raising concerns of depleting petroleum reserves coupled with global warming, the interest in Compression Ignition (CI) engines is more than ever primarily due to the comparatively superior efficiency of CI engines ... -
Application of Polyelectrolyte Complex Nanoparticles in Increasing the Lifetime of Poly(Vinyl Sulfonate) Scale Inhibitor in Berea Sandstone Rock
(University of Kansas, 2017-05-31)Water flooding is used extensively in oil fields to maintain reservoir pressure and displace oil. However, seawater containing high concentrations of sulfate ion may form scale precipitate when mixed with incompatible ... -
Modular Frequency Multiplier and Filters for the NASA Global Hawk Snow Radar
(University of Kansas, 2017-05-31)This thesis documents the process of adapting the 2-18 GHz Snow Radar to meet the requirements for operation on manned and unmanned platforms from 700 ft to 70,000 ft. The primary focus of this work is the development of ... -
