Determination of thermo-mechanical variables during plain strain compression testing
Plane strain compression (PSC) resting is a method used to simulate the deformation condition of industrial rolling, namely that of plane strain, and is used extensively to describe the influence of deformation variables, being strain, strain rate and temperature, on microstructural evolution. …

Assembly sequencing through graph reasoning : graph grammar rules for assembly planning
Assembly planning is difficult and tedious, but is necessary for complex products. This thesis presents a novel approach to automating assembly planning utilizing graph grammars. Computational geometric reasoning is used to produce a label rich graph from a CAD model. This graph is then modified by …

Phase Equilibria in Systems Containing Hydrocarbon, Water and Methanol
The role of methanol as a hydrate inhibitor has risen in industrial interest. It is found that methanol also stimulates production from retrograde gas condensate wells that show extensive productivity reduction because of near wellbore condensate buildup. The phase behavior of systems containing …

Scan test data compression using alternate Huffman coding
Huffman coding is a good method for statistically compressing test data with high compression rates. Unfortunately, the on-‐chip decoder to decompress that encoded test data after it is loaded onto the chip may be too complex. With limited die area, the decoder complexity becomes a drawback. This …
