Synthesis, characterization and applications of fats and oil derived phase change materials
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Phase Change Materials (PCM) are materials that absorb or release relatively large amounts of latent heat and are termed as "latent" thermal storage ... -
A study of parametric excitation applied to a MEMS tuning fork gyroscope
(University of Missouri--Columbia, 2007)The current MEMS ( gyroscopes which normally use the electro static force to excite the comb drive are faced with the limitations such as low precision, coupling problem, and poor robustness. We propose to use parametric ... -
State space formulation of TFEA & uncharted islands of instability in milling
(University of Missouri--Columbia, 2007)A new approach is developed to examine the stability of delay differential equations that builds upon the previous work in temporal finite element analysis. In contrast to the results of previous work, which could only be ... -
Ratiometric techniques to determine fluid viscosity using molecular rotors
(University of Missouri--Columbia, 2007)Molecular rotors exhibit viscosity-dependent quantum yield, potentially allowing measurements of fluid viscosity in non-mechanical manner. Several diseases are accompanied by blood plasma viscosity changes; therefore, a ... -
Photoacoustic discrimination of viable and thermally coagulated blood for burn injury imaging
(University of Missouri--Columbia, 2007)Early and accurate determination of burn depth is crucial to monitoring and treatment of the burn wound. One such treatment, surgical excision and grafting, involves removal of necrotic tissue from the wound and replacing ... -
Nitrification enhancement in lagoons using fixed film media
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Lagoons, commonly used in municipal wastewater treatment, are limited in their ability to treat wastewater due to limitations in the process and ... -
Near field microwave imaging techniques for embedded object detection and shape reconstruction
(University of Missouri--Columbia, 2007)A method for the detection, imaging and reconstruction of an embedded object through the application of a near field, frequency-synthesized microwave pulse is described. The work describes an alternate detection and ... -
Nanoporous carbon from corn cobs and its application
(University of Missouri--Columbia, 2007)Chemical activation of corn cobs using phosphoric acid or potassium hydroxide can lead to nanoporous carbon having surface area in excess of 3800 m²/g and pore volume of 2.5cc/g. Dried, crushed, corn cobs were carbonized ... -
Modeling of molecular and particulate transport in dry spent nuclear fuel canisters
(University of Missouri--Columbia, 2007)There are two important phenomena associated with the depressurization of a dry spent nuclear fuel canister after the formation of a through-wall pinhole breach. The first phenomenon is the release from the canister of any ... -
Modeling and analysis of nonlinear biological systems
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation focuses on the modeling and analysis of a set of biological phenomenon at a cellular (Part I) and systems (Part II) level. In Part ... -
Investigation of the "unit cell" concept for air-to-liquid heat exchanger research and development
(University of Missouri--Columbia, 2007)This study investigated the validity of the Unit Cell concept to explore the performance of air-to-liquid heat exchangers. The Unit Cell concept will test only a 15.24 cm by 15.24 cm portion of a full sized prototype coil, ... -
Investigation into the pool-boiling characteristics of gold nanofluids
(University of Missouri--Columbia, 2007)The use of nanofluids as a heat transfer fluid has drawn considerable attention recently. Within the last five years, work investigating the pool-boiling of these fluids has increased dramatically. However, they have ... -
Improving performance for adaptive filtering with voice applications
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Adaptive filtering is a common solution to many signal processing applications in which the environments are time varying. Its performance is limited ... -
Fluorescence spectroscopy and parallel factor analysis of waters from municipal waste sources
(University of Missouri--Columbia, 2007)Excitation-emission matrix (EEM) fluorescence spectroscopy is becoming a valuable tool for studying the complex nature of dissolved organic matter. EEMs can identify fluorescence emitting organic substances (fluorophores) ... -
