Inviscid Melt Spinning (IMS) has been shown to be appropriate for the production of mullite fibers. The formation of novel mullite fiber and the optimum processing conditions required to produce the fiber are described in two archival journal publications by Zhijun Xiao and the principal investigator. The development of a novel crucible design that was used to eliminate volatilization of SiO2 from the mullite melt and a corresponding change ...
The efficiencies of various data compression techniques as applied to color maps are compared. These color maps have certain special characteristics such as large homogeneous regions and fine detail such as lines and lettering. The color maps are first classified using the K means clustering algorithm with neighborhood classification. Three techniques are investigated - contour, quadtree and run-length coding. The run-length coding algorithm is modified to allow wrap around of ...
