Omputational perspectives of memory storage and gamma oscillation within the amygdala
(University of Missouri--Columbia, 2019)
., 2001; Rumpel et al., 2005). This dissertation describes computational modeling work that investigates the neuronal competition in the LA circuit that can shed light on understanding the mechanism behind this. Another important mechanism in the formation...
A high voltage piezoelectric transformer for active interrogation
(University of Missouri--Columbia, 2009)
A resonant piezoelectric transformer circuit was developed for high voltage generation. The goal of this project was to produce 100 kV with a reasonably sized piezoelectric crystal. Several mechanisms leading to less than ...
A MEMS based Coulter counter for cell sizing
(University of Missouri--Columbia, 2007)
Detection and classification of cells forms an important aspect of medical research in diagnosing diseases and finding remedies at the cellular level. Miniaturized cell detecting devices are desirable not only for on site ...
Spectroscopic ellipsometry analysis of nanoporous low dielectric constant films processed via supercritical carbon dioxide for next-generation microelectronic devices
(University of Missouri--Columbia, 2007)
My research will address issues at the back-end-of-line in microelectronics fabrication, specifically the need for Low-k extendibility. The International Roadmap for Semiconductors (2005) suggested that interconnect insulation must be replaced...
Microfabricated devices for single cell analysis
(University of Missouri--Columbia, 2006)
BioMEMS or lab-on-a-chip technology is promising technology and enables the possibility of microchip devices with higher throughput or better performance for single cell analysis. This technology is developed from the ...
Simulation of solar photovoltaic power station
(University of Missouri--Columbia, 2018)
It is predicted that in the 21st century, solar photovoltaic power generation will occupy an important seat of world energy consumption, and will replace some conventional energy. Solar photovoltaic power station is a kind ...
Biophysical modeling to reverse engineer two mammalian neural circuits lower urinar Y tract and hippocampus
(University of Missouri--Columbia, 2020)
Computational neuroscience provides tools to abstract and generalize principles of neuronal function using mathematics and computers. This dissertation reports biophysical modeling approaches to facilitate reverse engineering of two mammalian neural...
Self-aligned microchip device for automated measurement of quantal exocytosis
(University of Missouri--Columbia, 2010)
Here we describe a method to fabricate a multi-channel high-throughput microchip device for measurement of quantal transmitter release from individual cells. Instead of bringing carbon-fiber electrodes to cells, the device ...
Data control for signal scavenging for a personnel detection system
(University of Missouri--Columbia, 2010)
Injurious falls have been one of the major problems in elderly people and not providing medical assistance to those patients on time may increase complications. We developed a "Smart Carpet", which detects the personal ...
Wearable lip-based electrotactile display : feasibility study, modeling, and system design
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] For assisting visually impaired to effectively perceive critical spatial information through the sense of touch, we proposed a wearable lip-based ...
Computational modeling of the fear circuit : a system approach to understand anxiety and stress disorder
(University of Missouri--Columbia, 2009)
Computational models are becoming increasingly important to systems neuroscience. In fear learning, although there have been a few attempts at modeling emotional learning and memory in the past, most were limited to ...
Optically resonant structures for the enhancement of polycrystalline PbSe photoconductors
(University of Missouri--Columbia, 2018)
The mid-wave infrared (MWIR) regime of the electromagnetic spectrum is attractive for long-range imaging systems due to the atmospheric window between 3 and 5 [mu]m. Due to ambient thermal background, it is often necessary to operate sensor systems...
Linguistic summarization of human activity
(University of Missouri--Columbia, 2010)
The thesis advanced herein is that linguistic summarization is essential for the reliable succinct modeling and inference of human activity. It is also asserted that the inherent and unavoidable uncertainty is linguistic ...
