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 MMPI-2, MMPI-RC (Restructured Clinical), two alternative MMPI Personality Disorder Scales, and the MCMI-III were compared in a sample of 371 hospitalized psychiatric patients with Axis II discharge diagnoses. Participants were grouped by Cluster B Personality Disorders (93), Cluster C Personality Disorders (38), and participants without an Axis II diagnosis (240). Diagnostic utility of the instruments was compared in regards to DSM-IV-TR Axis II diagnoses. Analyses included utilizing discriminant function analysis to evaluate the diagnostic accuracy of each personality inventory. Further analyses provided information on two diagnostic validity statistics which included: positive predictive power (PPP) and incremental validity of positive test diagnoses (IPPP). The diagnostic validity statistics were used to evaluate which instrument has the most clinical and diagnostic utility in the differentiation of psychopathology. Analyses indicated that each of the instruments effectively predicted group membership at a rate better than chance and that no single instrument performed better or worse in this task. However, the MCMI-III possessed the greatest diagnostic validity as defined by the PPP and IPPP statistics. Thus, the initial hypothesis that the MCMI-III would have the most clinical utility in the assessment of personality disorders is partially supported. / Thesis (Ph.D.)--Wichita State University, College of Liberal Arts and Sciences, Dept. of Psychology

A methodology to determine the optimal capacitor locations and sizes to minimize line loss on a radial distribution system was developed in this work. Both the power loss index (PLI)-based approach and the loss sensitivity coefficient-based approach were comparatively studied to determine the optimal capacitor location. The index-based approach combined with a genetic algorithm was used to determine the capacitor sizes. After reactive power compensation voltage-dependent loads consume more power because of the increase in node voltage; therefore, customers pay more for their electricity while utilities experience savings from line-loss reduction. Therefore, a rationale for the necessity of reducing voltage for load demand reduction during reactive power compensation is presented, and the optimal voltage setting at the substation regulator is determined. The joint effect of ambient temperature, price, size, and phase kVAr of the capacitor on load, line loss, and generation is analyzed using a 24 factorial design. How consumer energy consumption, line loss, and generation are affected by voltage reduction is also evaluated. Since bus voltage also depends on line resistance, which varies with ambient temperature, the impact of temperature on power consumption, line loss, and generation is discussed as well. At reduced voltage, variations in line loss need to be analyzed, because losses affect the cost-benefit analysis. A model is derived that explains, at reduced voltage, how line loss varies with the type of load. Also analyzed is the effect of line resistance on line loss for various types of loads. The results of this work will improve the effectiveness and reliability of future voltage-reduction programs. Finally, analyses for negative line loss, higher voltage at the downstream node, and the active and reactive current components of a capacitor are presented in this work. / Thesis (Ph.D.)--Wichita State University, College of Engineering, Dept. of Electrical Engineering and Computer Science

Server virtualization has become the modern trend in various industries. Industries are resorting to the deployment of virtualized servers in order to cut the cost of additional, expensive hardware and consolidate the servers on minimal hardware for easier management and maintenance. Virtualized servers are often seen connected to disk arrays in many industries ranging from small to medium business to large data centers. In such a setup, assuring a low latency of data access from the disk array plays an important role in improving the performance and robustness of the overall system. Caching techniques have been researched and used in the past on traditional processors to reduce the number of memory accesses and have proven benefits in alleviating the response times of applications. The research done in this paper explores caching on the hypervisor and analyzes the performance of data cache locking technique in hypervisor caches. The research aims at reducing the Input / Output (I/O) latency in a server virtualized Storage Area Network (SAN) setup, which thereby increases the performance of applications running on the virtualized servers. The authors introduce a miss table that can determine the blocks of data in the hypervisor cache that need to be locked. Way cache locking method is used for locking, such that only selected lines of cache are locked (not the entire cache). The proposed cache locking technique is later evaluated with the introduction of a small victim buffer cache and probability based cache replacement algorithm. Valgrind simulation tool was used to generate memory traces by virtual machines (VMs). Experimental results show an improved cache hit percentage and a considerable reduction in the I/O response time due to the proposed cache locking technique when compared to the results without hypervisor cache locking. / Thesis (Ph.D.)--Wichita State University, College of Engineering, Dept. of Electrical Engineering and Computer Science

The research activity leading to this dissertation focused on the boundary treatment for computational fluid dynamics problems, especially those with unbounded domains. This involved a rigorous literature survey of boundary treatment techniques. The primary interest of this effort was on one of the emerging concepts of nonreflecting boundary treatment for numerical schemes, namely the perfectly matched layer (PML) absorbing technique. The need for an appropriate space-time transformation for a stable PML emphasized in previous efforts was the starting point for this developmental research activity. Based on this, unsplit PML equations were constructed for Euler equations linearized over a uniform mean flow with a proper space-time transformation. Dispersion analysis was carried out to demonstrate the effectiveness of the space-time transformation in terms of stability of the PML formulation. Numerous numerical simulations were carried out to investigate the stability of the PML formulation for long-term integration of various combinations of time-step size and PML parameters. The major focus of this research was to extend the construction of the PML for nonlinear Euler equations in a generalized coordinate system to widen its application in uniform and nonuniform grid structures. Emphasis was placed on the application of conventional numerical schemes without employing any form of artificial dissipation or numerical filtering. With this objective in mind, the split-form PML equations for nonlinear Euler equations were constructed. Various numerical simulations were carried out to validate the PML formulation and demonstrate its effectiveness as an absorbing boundary condition. / Thesis (Ph.D.)--Wichita State University, College of Engineering, Dept. of Aerospace Engineering.

Seventeen first graders participated in this study revolving around goal setting. The students were assigned to one of three treatment groups: (1) students who set their own goals, (2) students with teacher set goals, and (3) students with no pre-set goals. Students participated in weekly comprehension quizzes. Following the quizzes, students graphed their achievement and those in Group 1 set their reading goal for the following week, while Group 2 students received a goal from the teacher. Students in Group 3 received no pre-determined goals. All students from all groups were assessed on sight word recognition. The pre and post-test data for both reading comprehension and Dolch sight word recognition were examined statistically using analysis of variance. Results indicated that students in Group 1 made statistically significant gains in both comprehension and sight word recognition. There were no statistically significant differences among the three treatment groups in terms of gains made. / Thesis [M.Ed.] - Wichita State University, College of Education, Dept. of Curriculum and Instruction

This thesis assesses the use of the California Independent System Operator (CAISO) wholesale grid state indicator to enable price-responsive demand. This assessment is based on system and economic analyses for using the indicator to manage the operation of various smart grid technologies and applications. The system analysis was done by measuring the total and peak power reduction, as well as power loss using GridLAB-D software. The life cycle cost technique was applied to the economic analysis for different cases of battery energy storage technologies. / Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Electrical Engineering and Computer Science

This thesis investigates the feasibility of using Dynamic Inversion to develop control laws for time varying systems, specifically Miniature Morphing Air Vehicles. Two Linear Time Varying systems are investigated namely a pendulum of variable length and a miniature aircraft with the ability to change wing sweep. Simulations of the pendulum and the aircraft are provided with and without the control law in the loop. These simulations show the effectiveness of using dynamic inversion to control LTV systems. The aircraft model used in the simulations is a fourth order model which contains only the longitudinal dynamics. The stability and performance of the open and closed loop is investigated using a notion of LTV poles, that employ a time-varying Ricatti equation. This work also presents preliminary nonlinear aerodynamic model for a miniature aircraft which morphs through variable wing sweep. The estimation of the aerodynamics and the stability derivatives were conducted using Athena Vortex Lattice (AVL). Dynamic Inversion is used to design a control law using the nonlinear model of the aircrafts longitudinal dynamics. The nonlinear zero-dynamics are discussed and investigated for stability. The control law is validated by simulating the aircraft in a a pull up maneuver while simultaneously morphing. / Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Aerospace Engineering
