Advanced modeling and optimal control of a cart-double pendulum system
(University of Missouri--Columbia, 2019)
of this research is to design a controller that provides both energy and error minimization for the cart-pendulum, so that its payload moves as if it were floating freely in a microgravity environment (according to Newton's 1st law). The Euler-Lagrange equation...
Thermal characterization and scaling of a nanodielectric composite for use in compact ultra-high voltage capacitors
(University of Missouri--Columbia, 2019)
The University of Missouri has been developing compact capacitors for use in high voltage, pulsed power and directed energy applications. The capacitors are made from a proprietary nanodielectric, MU100, which is a polymer-ceramic composite composed...
Electrostatically actuated and bi-stable MEMS structures
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Bistable compliant micro-structures offer a tremendous advantage in the industry today, as these structures have an ability to maintain their shape ...
Modeling, design and control of forced-feedback metering poppet valve system
(University of Missouri--Columbia, 2006)
This research explores valve design, dynamic modeling, and techniques to achieve flow control for a forced-feedback metering poppet valve system. In particular, nonlinear and linear models of a forced feedback configuration ...
A comparison of modeling techniques: using the finite element method to determine local displacements in a human hip
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Artificial hip implant surgery is required by approximately 120,000 Americans each year. A typical hip replacement requires the surgical insertion of ...
Dynamic study of the piezo-driven pipettes in intracytoplasmic sperm injection
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Intracytoplasmic Sperm Injection (ICSI) is regarded as a critical assisted reproductive technology (ART) procedure in which a single spermatozoon is ...
High strain properties of advanced high strength spot welded steels
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This research was conducted to investigate and characterize the high strain rate compressive loading behavior of DP600 GI, an advanced high strength ...
Formulation development of a novel antivirulence compound for enhanced pharmocokinetic properties
(University of Missouri--Columbia, 2019)
, its clinical use is restricted by formulation challenges arising from its poor aqueous solubility. In this dissertation, plate-like or tube-like C790 nanoparticles with thickness down to one hundred nanometers have been successfully produced using...
Thermal-mechanical analysis of targets for high volume production of molybdenum-99 using low-enriched uranium
(University of Missouri--Columbia, 2009)
Techenetium-99m is diagnostic radioactive medical isotope that is currently used 30,000 times a day in the United States. All supplies of techenetium-99m's parent isotope molybdenum-99 currently originate from nuclear ...
Evaluation of process-structure-property relationships of carbon nanotube forests using simulation and deep learning
(University of Missouri--Columbia, 2020)
This work is aimed to explore process-structure-property relationships of carbon nanotube (CNT) forests. CNTs have superior mechanical, electrical and thermal properties that make them suitable for many applications. Yet, ...
Electron emission thermal energy conversion
(University of Missouri--Columbia, 2010)
Electron emission from a surface can be achieved via two mechanisms: tunneling and thermionics. Converting thermal energy to electrical power using these mechanisms is achieved by generation of an electron current from the ...
Numerical study of self-assembly of granular and colloidal particles
(University of Missouri--Columbia, 2021)
Self-assembly of granular materials and colloids are studied using several different computational methods such as Discrete Element Method (DEM), Smoothed Particle Hydrodynamics (SPH) method, finite volume Volume of Fluid ...
Numerical study of shock driven multiphase systems with reactions
(University of Missouri--Columbia, 2018)
