19F-NMR studies on anthrax toxin protective antigen
(Wichita State University, 2014-07)The anthrax protective antigen (PA) is a 83 kDa protein that is one of three protein components of the anthrax toxin, an AB toxin (two-component protein complexes secreted by a number of pathogenic bacteria) secreted by ... -
3D engineered capillary evaporators for enhanced critical heat flux and heat transfer coefficient in pool boiling and vapor chamber
(Wichita State University, 2020-07)A major challenge in pool-boiling heat transfer lies in the limit of the Critical Heat Flux (CHF) and Heat Transfer Coefficient (HTC), which is caused by the poor counterflow of liquid and vapor over a heated surface, ... -
A brain-inspired framework for evolutionary artificial general intelligence
(Wichita State University, 2020-05)From the medical field to agriculture, from energy to transportation, every industry is going through a revolution by embracing artificial intelligence (AI); nevertheless, AI is still in its infancy when compared to the ... -
A capillary surface with no radial limits
(Wichita State University, 2017-05)We begin by discussing the circumstances of capillary surfaces in regions with a corner, both concave and convex. These circumstances led to the (since proved) Concus-Finn Conjecture, which gives the requirements for a ... -
A case study of the integration of faith and learning at a Christian college
(Wichita State University, 2014-12)Many faith-based institutions articulate a mission of bringing faith and scholarship together. The integration of faith and learning is widely discussed, yet limited empirical research of the concept exists. This qualitative ... -
A clinical utility study of personality inventories: Concordance of the MCMI-III, the MMPI-2, the MMPI-RC, two alternative personality disorder scales, and Axis II discharge diagnosis in psychiatric inpatients
(Wichita State University, 2013-12)The Millon Clinical Multiaxial Inventory and the Minnesota Multiphasic Personality Inventory are two of the most common personality inventories used by clinicians for diagnostic purposes. Discriminant functions of the ... -
A community college Hispanic-serving institution: The effect of an HSI designation on organizational identity
(Wichita State University, 2015-05)Most community colleges receiving the Hispanic-Serving Institution (HSI) designation have no specific mission to serve Hispanic students. A lack of attention to assisting organizational members with what Hispanic-serving ... -
A comparative study on tongue muscle performance in weightlifters and runners
(Wichita State University, 2015-05)Various factors of physical exercise (e.g., mode, intensity) are known to affect directly and indirectly targeted muscles in the skeletal system, however, few research efforts have been directed towards delineating how ... -
A comparison of some numerical conformal mapping methods for simply and multiply connected domains
(Wichita State University, 2016-05)This dissertation compares several methods for computing conformal maps from sim-ply and multiply connected domains bounded by circles to target domains bounded by smooth curves and curves with corners. We discuss the use ... -
A comparison of two behavioral activation protocols
(Wichita State University, 2020-07)Behavioral activation (BA) is an empirically-supported treatment for major depressive disorder that seeks to increase overt behaviors as a way of countering withdrawal and passivity that often occurs during it. While some ... -
A DC-DC converter with high-voltage step-up ratio and reduced-voltage stress for renewable energy generation systems
(Wichita State University, 2018-12)This research work presents a high gain direct current-direct current (DC-DC) converter which is derived from a traditional boost converter. Electrical power systems are changing from a centralized generation model to a ... -
A facet level analysis of the concurrent and construct validity of the MCMI-III Grossman Facet Scales using the MMPI-2-RF specific problems scales as the criterion
(Wichita State University, 2016-07)Both the Millon Clinical Multiaxial Inventory-III (MCMI-III) and the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) are well established assessment instruments that were developed to help ... -
A fast time series power flow method for active distribution system control applications
(Wichita State University, 2021-05)Power system balancing, where supply of energy has to equal demand all time, is a very important constraint for electric power systems. In recent years, number of Distributed Energy Resources (DERs) and penetration of ... -
A foundation for a model of subjective value in free-to-play games
(Wichita State University, 2017-05)Mobile gaming is an emerging trend in the gaming community. Many of these games are known as "free-to-play" or "freemium". Users can play a mobile game for free, but can also purchase a large number of virtual goods ... -
A framework for measuring post-attack system-wide anonymity in anonymous communication systems
(Wichita State University, 2018-12)We develop techniques for measuring the amount of anonymity provided by anonymity systems in the aftermath of attacks. Anonymity systems are special systems that enable their users to carry out anonymous communication over ... -
A hybrid physics aware learning based transmission line resistance estimation algorithm for dynamic line rating application
(Wichita State University, 2021-05)The worldwide push towards a more intelligent, connected and reliable electric power delivery system has led to the propagation of a wide range of new technologies and ideas within the power grid infrastructure. Thus, the ... -
A meshing technique for unsteady computational fluid dynamics solutions for rapidly changing boundaries and internal configurations
(Wichita State University, 2015-05)A method to generate structured meshes is developed that allows for rapid re-meshing of CFD problems that have rapidly changing boundaries or internal configurations. These types of problems have typically been solved by ... -
