Development of an integrated approach combining artificial neural network material based on modeling with finite element analysis of forming processes
(University of Missouri--Columbia, 2005)
The use of a finite element model for design and analysis of a metal forming processes is limited by the incorporated material model's ability to predict deformation behavior over a wide range of operating conditions. ...
Torque ripple attenuation for an axial piston swash plate type hydrostatic pump: noise considerations
(University of Missouri--Columbia, 2006)
The main goal of this work is to reduce the disturbing noise generated by axial piston swash plate type hydrostatic pumps by attenuating the shaft torque variation. The analysis begins by deriving the equation of the shaft ...
Comprehensive optimization for thermoelectric refrigeration devices
(University of Missouri--Columbia, 2005)
A large market is currently in place for which thermoelectric (TE) technology can provide diverse energy solutions. This market should continue to grow as improvements are made to TE materials. In the last 10-15 years, ...
X-ray topography techniques for the analysis of laser irradiated silicon
(University of Missouri--Columbia, 2005)
There is currently much interest in femtosecond scale laser interactions with materials. Comparison of the damage produced by the femtosecond laser pulses to the longer laser pulses is also of interest. This study examined ...
Investigation of fanless PCs : design and optimization
(University of Missouri--Columbia, 2009)
The purpose of this research is to fundamentally explore the limitations of natural convection as it pertains to the cooling of desktop personal computers (PCs) and, in particular, maximize total thermal loads while ...
Signal processing techniques for nonlinearity identification of structures using transient response
(University of Missouri--Columbia, 2009)
