Bridge approach slab analysis and design incorporating elastic soil support
(University of Missouri--Columbia, 2011)The development of equations necessary for the analysis of finite bridge approach slabs (BAS) on elastic soil support is reported in this thesis. Results are compared for moments and shear forces governing the design for ... -
Characterization of ion sources for compact accelerator neutron production
(University of Missouri--Columbia, 2011)Compact neutron interrogation systems are a good candidate for use in active interrogation systems when large scale active or passive interrogation systems are not ideal. Field emitter arrays and plasma ion sources could ... -
Characterizing optical properties in fibrous tissues
(University of Missouri--Columbia, 2011)Optical methods are promising for non-invasive tissue characterization. Biological tissues can be classified into isotropic tissues and anisotropic tissues. The optical properties of isotropic tissues such as adipose tissue ... -
Computational models of neuronal fear and addiction circuits
(University of Missouri--Columbia, 2011)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Computational Neuroscience provides tools to abstract and generalize principles of neuronal functions using mathematics, with applicability to the ... -
The Design and analysis of a HA/PLA pedicle screw for spinal fusion
(University of Missouri--Columbia, 2011)Metallic pedicle screws have been widely used in the orthopaedic field to treat spinal diseases. Although spinal screws have improved over the last few decades, there is still sometimes a need for a second painful surgery ... -
Design and optimization of a Mars sample return mission with nuclear thermal rockets
(University of Missouri--Columbia, 2011)Nuclear thermal propulsion (NTP) is recognized as the only solution to human exploration of the near planets during the next several decades, but NTP currently receives little funding for development. In order to foster ... -
Design and simulation analysis of MEMS parallel plate capacitor models for voltage conversion and power harvesting
(University of Missouri--Columbia, 2011)In environment, unwanted and undamped vibrations are abundantly available which can be converted into electrical energy and used for energy harvesting. This paper contains the design, modeling and simulation results of ... -
Determining the relative effects of volumetric water content and dry density on the dielectric constant of soils
(University of Missouri--Columbia, 2011)Non destructive subsurface investigation using electromagnetic (EM) waves is a growing technique in geotechnical engineering (Mohamed 2006). The ability to "see" under the Earth's surface without having to excavate is ... -
Development and application of variable rate irrigation techniques on non-uniform soils using center-pivot irrigation systems
(University of Missouri--Columbia, 2011)Variable rate irrigation was studied for the production of corn and rice on a nonuniform soil texture using a three tower, conventional, center-pivot irrigation system on the East Marsh Pivot (Marsh Pivot) at the University ... -
Dynamic simulation of particulate and molecular systems
(University of Missouri--Columbia, 2011)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Granular packing of millimeter-scale and micrometer-scale particles with three different size distributions (monosize, bimodal and Gaussian) are studied ... -
Electrospinning collagen and hyaluronic acid nanofiber meshes
(University of Missouri--Columbia, 2011)Osteoporosis is a worldwide burden affecting over 200 million people. There are many risk factors associated with osteoporosis, but they all lead to decreased bone strength and an increased chance of bone fracture. The ... -
Ensemble acoustic modeling in automatic speech recognition
(University of Missouri--Columbia, 2011)In this dissertation, several new approaches of using data sampling to construct an Ensemble of Acoustic Models (EAM) for speech recognition are proposed. A straightforward method of data sampling is Cross Validation (CV) ... -
Exploring passive heartbeat detection using a hydraulic bed sensor system
(University of Missouri--Columbia, 2011)Sleep monitoring of heartbeat, respiration and restlessness can help to detect sleep disturbances which may be indicative of poor health and functional deficits, especially in older adults. This work investigates a new ... -
Fabrication and characterization of heat flux sensor using polymer derived ceramics
(University of Missouri--Columbia, 2011)In this study, a free standing Resistance Temperature Detector (RTD) sensor made from Polymer Derived Ceramics (PDCs) for high temperature application (above 1000[degrees]C) is fabricated. A newly developed fabrication ... -
Flapping wing dynamics of MAVs : nonlinear modeling and experimental investigation
(University of Missouri--Columbia, 2011)Analysis of the flapping-wing motion of micro air vehicles (MAVs) is a complex problem that involves nonlinear structural analysis coupled with unsteady fluid mechanics analysis. In this study I apply a fully nonlinear ... -
High-accuracy skin lesion segmentation and size determination
(University of Missouri--Columbia, 2011)Melanoma is one of the most common skin cancers. 5% of all cancer cases that occur in a year are cases of skin cancer and many people die each year by melanoma because of late recognition. Moreover, the number of new cases ... -
Integrate template matching and statistical modeling for continuous speech recognition
(University of Missouri--Columbia, 2011)In this dissertation, a novel approach of integrating template matching with statistical modeling is proposed to improve continuous speech recognition. Commonly used Hidden Markov Models (HMMs) are ineffective in modeling ... -
Management of disinfection byproduct production in small drinking water systems
