Modeling tools and prototype design of loop heat pipe for electronics cooling
(University of Missouri--Columbia, 2009)
In this dissertation, a set of modeling tools for loop heat pipe (LHP) design is developed, and original analytical models for annular two-phase flow are proposed. LHPs are promising two-phase thermal transport devices for ...
Mechanical behavior of transparent fiber reinforced polyester composites at extreme temperatures
(University of Missouri--Columbia, 2018)
Selecting materials for harsh or extreme environmental conditions can be a challenge. The combination of a harsh environment, large forces over extended periods and the need for lowest possible cost restricts the choice ...

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 ...
Carbon nanotube forests: synthesis, patterning, milling, mechanics, and applications
(University of Missouri--Columbia, 2018)
Carbon nanotube (CNT) forests are a nano-structured material consisting of vertically oriented carbon nanotubes. The material has many exceptional and unique physical properties that have motivated considerable research ...
Hydro-mechanical analysis of low enriched uranium fuel plates for University of Missouri Research Reactor
(University of Missouri--Columbia, 2012)
As part of the Global Threat Reduction Initiative (GTRI) Reactor Conversion program, work is underway to analyze and validate a new fuel assembly for the University of Missouri Research Reactor (MURR). The Low Enriched ...
Condition-based monitoring system for diagnostics and prognostics of centrifugal pumps
(University of Missouri--Columbia, 2016)
Centrifugal pumps are the most commonly used pumps in industry. Therefore, maintenance is a very important part of the pump's life cycle. This work presents a systematic robust conditionbased monitoring process for diagnostics ...
