Models of neuronal subcircuits in the crustacean cardiac ganglion and the mammalian perirhinal cortex
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation deals with four related studies that involve simulations of computational models of neurons and neuronal networks at varying levels of complexity...
Implementation of finite impulse response (FIR) filter as test application on general purpose evolutionary algorithm testbed system
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A 19th order Finite Impulse Response (FIR) filter is implemented as a test application for Gpeat, a general purpose evolutionary algorithm testbed. The filter is used...
MEMS Coulter counter for dynamic impedance measurement of time sensitive cells
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this research, a MEMS Coulter counter is designed, modeled, fabricated and characterized, which can detect and monitor the dynamic cell impedance changes in situ as a...
Effects of nano-second pulsed electric fields on human breast cancer cell line-MCF7
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Effects of nanosecond pulsed electric fields on the human breast cancer cell line MCF-7 have been investigated for changes in cell number, DNA concentration, DNA synthesis rate...
Significance-linked connected component analysis+ for wavelet image coding
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The Significance-Linked Connected Component Analysis+ (SLCCA+) is a efficient wavelet image coding algorithm that extends SLCCA by using new data organization and representation...
Human fall detection using a circular audio sensor array
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] According to the U.S. Census Bureau estimate (March 2010), there were 38.9 million people 65 years and older in the United States in 2008. In 2005, 15,800 people 65 years...
Frame interpolation in H.264
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In video transmission over low-bandwidth networks, videos are often encoded at low frame rates. At the decoder side, frame interpolation is often performed to reconstruct...
