Application of pulsed electric fields and magnetic pulse compressor technology in water disinfection
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Pulsed electric field (PEF) is a promising technology for the non-thermal disinfection of water. Although research has already been conducted on the ...
Turbo equalization in wireless communication
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Intersymbol interference (ISI) is a major impairment in wireless communication and hence equalization is applied to combat such interference. In addition ...
Transmission distortion modeling for wireless video communication
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A major challenge in video wireless communication is that the channel is time-varying and error-prone. The lost video packet and the packet received ...
Decadal mass balance of the Antarctic ice sheet from satellite radar altimetry and its contribution to global sea level change
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this research, we estimated the decadal mass balance of the Antarctic ice sheet using the European Space Agency's ERS-1 and ERS-2 satellite radar ...
Classical and neural net control and identification of non-linear systems with application to the two-joint inverted pendulum control problem
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A two joint inverted pendulum control system is an example of a highly nonlinear dynamic system which is investigated in this thesis in terms of control ...
Optimal video sensing strategy and performance analysis for wireless video sensors under delay constraints
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A wireless sensor network (WSN) is a system of spatially distributed sensors that capture, process and transmit information over a mobile wireless ...
Enhancing the IKE preshared key authentication method
(University of Missouri--Columbia, 2006)
Internet Key Exchange (IKE) protocol is part of the IP Security (IPsec) protocol suite. It is responsible for generating and maintaining Security Associates and for establishing session keys between two entities before ...
Photoswitch-based Class E microwave power amplifer
(University of Missouri--Columbia, 2007)
Currently radar systems have problems with power losses and efficiency, so more power is used and more heat removal is needed. The primary source of loss is the final amplifier in the transmission-receive (TR) module. The ...
Design of a single sided linear induction motor (SLIM) using a user interactive computer program
(University of Missouri--Columbia, 2005)
This project studies the design of SLIM, which can be used to power capsules in a pneumatic capsule pipeline (PCP) system. The design equations of the SLIM and the equivalent circuit model are studied and discussed in ...
Synthesis of ordered nanoenergetic composites
(University of Missouri--Columbia, 2005)
Energetic materials can be defined as the substances or mixtures that react chemically to release energy required for their intended application. Thermite is a subgroup of pyrotechnic, a class of energetic material. ...
Performance analysis of high power photoconductive switch at elevated temperature
(University of Missouri--Columbia, 2005)
This project deals with the analysis of high power radio frequency effects on a non-linear opposed contact GaAs photoconductive semiconductor switch, used in high power microwave generation. Specifically, effects of heating ...
