Analysis of heat transfer in subcooled metal powder subjected to pulsed laser heating
(University of Missouri--Columbia, 2005)
The interaction of metal powder and pulsed laser heat flux is investigated on two levels, the powder bed level and the particle level. The locations of the thermal penetration depth and the liquid-solid interface are ...
Infiltration and solid-liquid phase change in porous media
(University of Missouri--Columbia, 2009)
Many natural phenomenon and engineering systems involves phase change and infiltration in porous media. Some examples are the freezing of soil, frozen food, water barrier in construction and mining processes, chill casting ...
Modeling of selective laser sintering of single-component metal powders
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Selective Laser Sintering (SLS) is a rapid prototyping technology which enables freeform fabrication of complex-geometry components directly from ...
Analysis and modeling of direct selective laser sintering of two-component metal powders
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Direct Selective Laser Sintering (SLS) is an emerging technology of Solid Freeform Fabrication (SFF) that 3-D parts are built from the metal-based ...
Real-time speaker-independent large vocabulary continuous speech recoginition
(University of Missouri--Columbia, 2005)
In this dissertation, a real-time decoding engine for speaker-independent large vocabulary continuous speech recognition (LVCSR) is presented. Three indispensable and correlated performance measurements -- accuracy, speed, ...
