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, ...
Parametric study of the shock driven multiphase flow
(University of Missouri--Columbia, 2018)
This thesis presents a study of the shock driven multiphase instability and explores the competing effects of particle and gas effects in mixing. Eight different simulations were carried out to study properties of the ...
Multiscale phase change, heat and mass transfer in direct contact membrane distillation
(University of Missouri--Columbia, 2020)
The global water shortage has become a serious threat for the world and the most promising solution for the water issue is the desalination of seawater or brackish water. In this work, direct contact membrane distillation ...
Validating the use of machine learning techniques in evaluating additive manufactured elastic materials
(University of Missouri--Columbia, 2020)

Signal processing techniques for nonlinearity identification of structures using transient response
(University of Missouri--Columbia, 2009)
In this work, an alternate method for determining nonlinearity of vibrating structures is investigated. In contrast to previous approaches, transient vibrations have been used in combination with advanced signal processing ...
Nanomechanical property characterization of femoral head materials
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Orthopedic Implants under long-term physiological loading could produce changes in the surface mechanical properties and possible failure. The knowledge ...
Modeling of selective laser sintering of single-component metal powders

Analysis and modeling of direct selective laser sintering of two-component metal powders
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Direct Selective Laser Sintering (SLS) is an emerging technology of Solid Freeform Fabrication (SFF) that 3-D parts are built from the metal-based ...
Characterization of drillability of sandwich structure of carbon fiber reinforced epoxy composite over titanium alloy
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Composite-over-Titanium structures are the major candidates for substitution of conventional materials in aerospace industries. This paper investigates ...
Galilean moon tour using simplified trajectory computational techniques
(University of Missouri--Columbia, 2006)
It is desired to find a trajectory for a spacecraft that will capture into an orbit about Jupiter and then subsequently capture into an orbit about each of the Galilean moons. The two main variables are the mass ratio, ...
Nonlinear control and active damping of a forced-feedback metering poppet valve
(University of Missouri--Columbia, 2007)
For a metering poppet valve which was developed at the University of Missouri (MU valve), the valve can be configured for performance at the cost of stability. It is desirable to achieve both performance and stability using ...
Theoretical and experimental investigation of oscillating heat pipes
