Therapeutic applications for pulsed laser and ultrasound
(University of Kansas, 2019-08-31)Arthrofibrosis is a condition that causes a painful reduction in joint range of motion, which is caused by a buildup of scar tissue in and around joint. The overall goal of this research project was to develop new non-invasive ... -
Pore-Scale Network Modeling of Microporosity in LowResistivity Pay Zones of Carbonates
(University of Kansas, 2019-08-31)Carbonates present an important research area as classical empirical methods primarily developed for sandstone characterizations give erroneous results when being applied to carbonates. Specifically, the question of ... -
A Comparative Study on Polyp Classification and Localization from Colonoscopy Videos
(University of Kansas, 2019-08-31)Colorectal cancer is one of the most common types of cancer with a high mortality rate. It typically develops from small clumps of benign cells called polyp. The adenomatous polyp has a higher chance of developing into ... -
Radome Design and Curvature Effects on Antenna Performance, with Application to Radar Array Installation in Transonic Aircraft
(University of Kansas, 2019-08-31)Significant and fast changes in the cryosphere have been observed and monitored using radioglaciology and remote sensing technology. A fuselage mounted Ultrawideband Multichannel Coherent Radar Depth Sounder (UWB MCoRDS) ... -
Quantitative Assessment of Magnetic Resonance Spectroscopy Data Reconstruction Methods: Region-of-Interest Averaging and Spectral Localization by Imaging
(University of Kansas, 2019-08-31)The aim of this dissertation was to compare two magnetic resonance spectroscopy (MRS) localization techniques: Fourier based region-of-interest (ROI) averaging, and the non-Fourier based spectral localization by imaging ... -
Estimation of The Effect of Rain and Incidents on Freeway Capacity and Free-Flow Speed
(University of Kansas, 2019-08-31)The goal of this thesis was to examine the effect of incidents and adverse weather (rain) on capacity and Free-Flow Speed (FFS). Data were collected from multiple freeway segments in Kansas City, Kansas from 2014 to 2018. ... -
INVESTIGATION OF SOIL ARCHING UNDER DIFFERENT MODES OF SOIL MOVEMENT AND SURFACE LOADING
(University of Kansas, 2019-08-31)Soil arching exists in many geotechnical applications, including tunnels, buried pipes and culverts, and Geosynthetic-Reinforced Pile-Supported (GRPS) embankments. The existence of these buried structures or structural ... -
Toluene Removal from Produced Water by Biofilm Granular Activated Carbon System
(University of Kansas, 2019-05-31)Over the last several decades, new strategies for oil and gas produced water disposal have been explored due to concern over increasing seismicity in areas surrounding deep well injection sites. A large area of research ... -
Experimental and Numerical Investigations of Wettability of Positive Electrodes for Li−O2 Batteries
(University of Kansas, 2019-05-31)The objective of this dissertation is to characterize the positive electrode wettability and its effects on the performance (e.g., discharge capacity) of Li−O2 batteries. The investigations include an experimental study ... -
Modeling, Visualizing, and Analyzing Student Progress on Learning Maps
(University of Kansas, 2019-05-31)We present a design in which data visualization techniques are applied to meet the needs of teachers and education researchers in analyzing and responding to student learning. Developed using the iterative process fundamental ... -
Methane Reforming on Single Atom Catalysts
(University of Kansas, 2019-05-31)Heterogenous catalysis is a key process in chemical conversion and energy application. The catalytic performance is determined by the structure and properties of catalytic active sites under working conditions, which are ... -
Waste Heat Recovery From a Compression Ignition Engine using a Combined Diesel Particulate Filter Heat Exchanger
(University of Kansas, 2019-05-31)Compression ignition (CI) engines have been a figurehead in the transportation industry for decades. However, as environmental regulations dictate increasingly strict emissions guidelines for engines, technologies must ... -
Performance Analysis of Mobile Ad Hoc Network Routing Protocols Using ns-3 Simulations
(University of Kansas, 2019-05-31)Mobile ad hoc networks (MANETs) consist of mobile nodes that can communicate with each other through wireless links without reliance on any infrastructure. The dynamic topology of MANETs poses a significant challenge for ... -
Tunable Surface Plasmon Dynamics
(University of Kansas, 2019-05-31)Due to their extreme spatial confinement, surface plasmon resonances show great potential in the design of future devices that would blur the boundaries between electronics and optics. Traditionally, plasmonic interactions ... -
Geosynthetic-Reinforced Retaining Walls with Flexible Facing Subjected to Footing Loading
(University of Kansas, 2019-05-31)Geosynthetic-reinforced retaining (GRR) walls have been used as bridge abutments to support shallow foundations. This technology eliminates the need for traditional deep foundations, such as piles, to support bridges. ... -
Use of Multiscale Entropy to Characterize Fetal Autonomic Development
