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 ...
A method of frequency domain error modeling to predict the probability of stability and performance of dynamic systems with parametric uncertainty
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In this work a method is developed for modeling frequency domain error in dynamic systems with parametric uncertainty. Within any mass-manufactured ...
New tool design for measuring tool displacement in milling
(University of Missouri--Columbia, 2012)
Monitoring tool displacement during a milling process allows the operator to identify when there is relative movement between the cutting tool and the workpiece. When the relative movement between the cutting tool and the ...
An investigation into gravity independent oscillating heat pipes
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A number of oscillating heat pipes (OHPs) with unbalanced structures were investigated in an effort to develop methods enabling OHPs to be gravity ...
A comprehensive model for energy transport and ablation of metal films induced by ultrashort pulsed lasers
(University of Missouri--Columbia, 2012)
A comprehensive laser material ablation model was developed to describe energy transport, ultrafast phase changes, and material ablation of metal films irradiated by ultrashort laser pulses. The two optical models were ...
Plasmonic Au nanostructures for surface-enhanced raman spectroscopy
(University of Missouri--Columbia, 2013)
Raman spectroscopy is a spectroscopic technique that provides rich structural information for identifying chemical species but finds limited applications owing to its low sensitivity. Surface-enhanced Raman spectroscopy ...
Ab initio molecular dynamics study of nanoscale heat transfer and energy conversion
(University of Missouri--Columbia, 2013)
In this thesis, ab initio molecular dynamics simulation based on a plane wave/pseudopotential implementation of density functional theory was adopted to investigate nanoscale heat transfer and energy conversions for ...

Dental composites reinforced with zinc oxide nanofillers
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Dental composites suffer from inadequate mechanical properties and formation of secondary caries, which could lead to the increased failure rate of ...
Design, analysis and dynamic phenomena of MEMS capacitive power harvester
(University of Missouri--Columbia, 2015)
Unwanted vibrations are all around us in our daily life. These vibrations can effectively be converted into electrical power through capacitive device. Even though the amount of power generated is small ([mu]W), it is still ...
Flooded two-phase flow dynamics and heat transfer with engineered wettability on microstructured surfaces
(University of Missouri--Columbia, 2015)
Due to excessive droplet feeding, a period of flooding occurs as part of a typical droplet based thermal management cycle. The conventional superhydrophilic surface, which is designed for thin film evaporation because of ...
Superharmonic Responses of an Oscillator with Impact
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Superharmonic responses are characteristic of many nonlinear systems undergoing high intensity of excitation. Recent experimental investigation findings ...
Cruise flight optimization of a commercial aircraft with winds
(University of Missouri--Columbia, 2015)
With high prices for fuel and airfare, companies are looking to minimize operational costs. Reducing aircraft fuel consumption is one strategy companies use to lower costs. During flights, commercial aircraft divide the ...
