Evidentialist Foundationalist Argumentation in Multi-Agent Systems
(University of Kansas, 2012-05-13)This dissertation focuses on the explicit grounding of reasoning in evidence directly sensed from the physical world. Based on evidence from human problem solving and successes, this is a straightforward basis for reasoning: ... -
Wellbore Heat Transfer Model for Wax Deposition in Permafrost Region
(University of Kansas, 2012-05-31)Producing waxy oil in arctic area may cause wax deposited on the well wall. Since wax deposition is strongly thermal related, accurate heat transfer model is necessary in predicting and preventing wax depostion. A mathematical ... -
Computational Molecular Design Using Tabu Search
(University of Kansas, 2012-05-31)The focus of this project is the use of computational molecular design (CMD) in the design of novel crosslinked polymers. A design example was completed for a dimethacrylate as part of a comonomer used in dental restoration, ... -
Design and Experimental Characterization of an Erbium Doped GaN Waveguide
(University of Kansas, 2012-05-31)ABSTRACT The goal of this research was to develop an optical amplifier based on Erbium doped GaN waveguides, which can be used in the next-generation of planar integrated optic circuits. This thesis started from the basic ... -
IMPROVING AND EXPANDING PRECISION ORBIT DERIVED ATMOSPHERIC DENSITIES
(University of Kansas, 2012-05-31)Atmospheric drag is the most uncertain non-conservative force acting on a low Earth orbiting satellite. The existing atmospheric density models are not accurate enough to model the variations in density, which significantly ... -
Geomorphic Equations and Methods for Natural Channel Design
(University of Kansas, 2012-05-31)Natural channel design in river engineering is the philosophy and practice of designing stream channels by copying or mimicking the geomorphology of stable, self-formed streams. This dissertation presents methods and ... -
A UNIFIED HARDWARE/SOFTWARE PRIORITY SCHEDULING MODEL FOR GENERAL PURPOSE SYSTEMS
(University of Kansas, 2012-05-31)Migrating functionality from software to hardware has historically held the promise of enhancing performance through exploiting the inherent parallel nature of hardware. Many early exploratory efforts in repartitioning ... -
Evaluation of Lateral Behavior of Pile-Supported Bridges under Scour Conditions
(University of Kansas, 2012-05-31)Scour is the removal of soils in the vicinity of bridge foundations, resulting in a reduced capacity of the foundations, which may lead to a bridge failure. Scour causes 60% of bridge failures in the United States. To ... -
The Development of Goat Models to Evaluate the Effectiveness of Negative Pressure in Promoting Tissue Ingrowth into Porous Metal Implants
(University of Kansas, 2012-05-31)The repair of large segmental bone defects is problematic with a high risk of infection, large amounts of soft tissue damage, and fracture stabilization difficulties. This preliminary study evaluates three large animal ... -
Characterization of the Hydrogen-Bromine Flow Battery for Electrical Energy Storage
(University of Kansas, 2012-05-31)A low-cost and efficient electrical energy storage system is needed to implement intermittent renewable energy sources such as solar and wind while maintaining grid reliability, and could also reduce the use of inefficient ... -
Flows of Incompressible Newtonian and Generalized Newtonian Fluids over a Circular Cylinder
(University of Kansas, 2012-05-31)This thesis presents numerical solutions of the boundary value problems describing the isothermal and non-isothermal steady flows of incompressible Newtonian, power-law and Carreau fluids over a circular cylinder using the ... -
Development of an in situ Remediation Strategy for a Metals-Contaminated, Alkaline Groundwater
(University of Kansas, 2012-5-31)Groundwater beneath a former industrial site in Tukwila, WA contains dissolved metals and organic material at high levels, as well as elevated pH (10-12). Contaminated groundwater discharge to site-adjacent waterways must ... -
A Family of Joint Sparse PCA Algorithms for Anomaly Localization in Network Data Streams
(University of Kansas, 2012-05-31)Determining anomalies in data streams that are collected and transformed from various types of networks has recently attracted significant research interest. Principal Component Analysis (PCA) is arguably the most widely ... -
Design, Construction, and Validation of an In-Cylinder Pressure Recording System for Internal Combustion Engine Analysis
(University of Kansas, 2012-05-31)Due to an increased global interest in sustainable energy sources, it is imperative that the transportation sector find substitutes for the limited petroleum supply, such as biodiesel. This thesis contains three sections ... -
Development Of a Control System For a 2D Biped Walking Robotic Testbed
(University of Kansas, 2012-05-31)Due to the great potential promise of bipedal walking robots, it was determined that the Jaywalker, a first generation bipedal walking testbed, should be designed and built as a platform for the study of bipedal walking ... -
Exploring the Suitability of Existing Tools for Constructing Executable Java Slices
(University of Kansas, 2012-05-31)Java is a managed programming language, and Java programs are executed in a virtual machine (VM) environment. Java VMs not only execute the primary application program, but also perform several other auxiliary tasks at ... -
