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 ... -
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 ... -
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 ... -
Maximum-range trajectories for an unpowered reusable launch vehicle
(University of Missouri--Columbia, 2011)A software package has been developed that numerically maximizes the range of an unpowered reusable launch vehicle (RLV) during the Terminal Area Energy Management (TAEM) phase of reentry into Earth's atmosphere by adjusting ... -
Mean grain size estimation for copper-alloy samples based on attenuation coefficient estimates
(University of Missouri--Columbia, 2011)A polycrystalline metal's grain size affects its mechanical properties; therefore, the ability to effectively and easily monitor grain size during a manufacturing process is critical. Conventional destructive tests utilized ... -
Modeling a hydraulic hybrid drivetrain : efficiency considerations
(University of Missouri--Columbia, 2011)Increasing petroleum prices and environmental concerns have caused a demand for more fuel efficient vehicles. Hybrid vehicles provide a solution to this demand, and hydraulic hybrid vehicles are shown to have a cheaper ... -
Thermal-mechanical analysis of a low-enriched uranium foil based annular target for the production of molybdenum-99
(University of Missouri--Columbia, 2011)One of the US department of Energy's global threat reduction initiative goals is to eliminate the use of high-enriched uranium from the production of the radio-isotope Molybdenum-99. One strategy to achieve this goal is ...
