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 ...
Performance evaluation of a low cost processor with wireless connectivity
(University of Missouri--Columbia, 2005)
This study shows the development and analysis of the connectivity of a wireless system using a low cost processor. First, we designed a system with two sensor processors and a server PC. Second, we developed two protocols; ...
Mobile speed estimation for hierarchical wireless network
(University of Missouri--Columbia, 2005)
The implementation of hierarchical cellular system, which can effectively reduce the number of handoffs thus significantly improve the overall system capacity, requires the knowledge of mobile user speed at the base station. ...
Optimization of charge collection efficiency in MSM photodetector
(University of Missouri--Columbia, 2005)
The effects of different geometries, heights and concentrations per unit area of gratings in the active region of a metal semiconductor metal photo-detector have been analyzed for enhanced charge collection through ...
Automated building footprint extraction from high resolution LIDAR DEM imagery
(University of Missouri--Columbia, 2005)
Geographic Information Systems (GIS) are used in the fields of urban planning, environmental management, agriculture, transportation, utilities etc. because of their ability to provide geospatial information organized in ...
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 ...
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. ...
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 ...
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 ...
Developing neural network applications using LabVIEW
(University of Missouri--Columbia, 2005)
Artificial Neural Networks (ANN) have gained tremendous popularity over the last few decades. They are considered as substitutes for classical techniques which have been followed for many years. Many neural network ...
