Analysis of the potential for flow-induced deflection of nuclear reactor fuel plates under high velocity flows
(University of Missouri--Columbia, 2015)The University of Missouri Research Reactor (MURR) is one of five High Performance Research Reactors(HPRRs) in the U.S. that still utilizes high enriched uranium (HEU) fuel. Currently, a novel LEU fuel is under consideration ... -
Analytical earth-aerocapture guidance
(University of Missouri--Columbia, 2020)Aerocapture is a technique of employing a single atmospheric pass to inserts a spacecraft from a hyperbolic orbit, approaching from deep space, into an elliptical (captured) orbit around its destination planet. After ... -
Application of microturbines in improving the energy efficiency of municipal wastewater treatment plants in Missouri.
(University of Missouri--Columbia, 2021)Hydropower is a source of renewable energy. It is possible to combine a hydropower installation with an existing wastewater plant while ensuring it still performs its basic purpose. The multipurpose scheme would be integrated ... -
Applying and analyzing robust modern control on uncertain hydraulic systems
(University of Missouri--Columbia, 2006)In this work modern robust control systems are designed and compared to standard techniques for a hydraulic implement system. The system includes an independent metering valve (IMV) and a variable displacement pump. The ... -
Assessing mechanical properties of the cardiovascular system
(University of Missouri--Columbia, 2020)The elasticity of wall of the arteries plays a significant role in cardiovascular system. Capacitance of the aorta is predicative of cardiovascular events[1]. To get better understanding the function of the cardiovascular ... -
Asymmetric responses in symmetrical structures

Attenuation of low frequency pressure pulsations
(University of Missouri--Columbia, 2021)In this thesis, the concept of hydraulic pulsating filter is explored and developed. The filter or resonator is designed to attenuate the pulsation that occurs when the hydraulic pump is discharged. Pumps pulsate over a ... -
Automated trajectory generation and guidance for a new launch vehicle flight phases
(University of Missouri--Columbia, 2010)Much effort has been put into developing technologies for next generation re-usable launch vehicles. Fully re-usable launch vehicles include a booster stage that is designed to land, usually near the launch site, after it ... -
Automatic oxygen controller design for premature infants with clinical evaluation
(University of Missouri--Columbia, 2020)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] For premature infants, the peripheral oxygen saturation (SpO2) level has significant effects on their health. Manual adjustment of fraction ... -
An axisymmetric interfacial tracking model for melting-vaporization-resolidification in a thin metal film irradiated by pico to femtosecond pulse lasers
(University of Missouri--Columbia, 2010)A two dimensional axisymmetric, interfacial tracking method is developed to model rapid melting and solidification of a free standing metal film subjected to an ultra-short laser pulse. Finite volume method is employed to ... -
Bifurcation analysis and damage detection in mechanical structures
(University of Missouri--Columbia, 2018)Bifurcation and damage are two phenomena prompting any structure to unpredicted failure. Their early detection is crucial to maintaining structural health and integrity. In this work, we investigate two topics in bifurcation ... -
Blackbody temperature calculations from visible and newa-IR spectra for gas-fired furnaces
(University of Missouri--Columbia, 2005)The goal of this research work is to develop a system capable of measuring multiple factors of interest in the operation of gas-fired furnaces. The primary focus is the development of a model for calculating wall or flame ... -
Broadband, reconfigurable and multifunctional elastic wave control with smart metamaterials
(University of Missouri--Columbia, 2017)Over the past two decades, an extensive research effort has been devoted to elastic metamaterials, structured artificial materials at subwavelength scales, for elastic wave manipulations in solids. Due to the extreme values ... -
Carbon nanotube forests: synthesis, patterning, milling, mechanics, and applications
(University of Missouri--Columbia, 2018)Carbon nanotube (CNT) forests are a nano-structured material consisting of vertically oriented carbon nanotubes. The material has many exceptional and unique physical properties that have motivated considerable research ... -
Characterization and nondimensional analysis of a variable speed centrifugal pump
(University of Missouri--Columbia, 2014)When dealing with centrifugal pumps in the aerospace field, current industry standards dictate the use of single speed drive pumps. The performance of these pumps is then modulated using simply an electromechanical valve, ... -
