Reaction and Coloration of Glasses with Hydrogen

The reaction of NBS 710 glass with hydrogen at 500°C and the resulting coloration of the glass have been studied using optical spectroscopy. Initially the reaction leads to the reduction of iron from ferrous to ferric state which subsequently combines with sulfur resulting in the formation of FeS. The origin of the color centers is proposed to be related to the formation of FeS.     

Scalable Parallel Algorithms for Geometric Pattern Recognition

This paper considers a variety of geometric pattern recognition problems on input sets of size n using a coarse grained multicomputer model consisting of p processors with Ω(n/p) local memory each (i.e., Ω(n/p) memory cells of Θ(log n) bits apiece), where the processors are connected to an arbitrary interconnection network. It introduces efficient scalable parallel algorithms for a number of geometric problems including the rectangle finding problem, the maximal equally spaced collinear points problem, and the point set pattern matching problem. All of the algorithms presented are scalable in that they are applicable and efficient over a very wide range of ratios of problem size to number of processors. In addition to the practicality imparted by scalability, these algorithms are easy to implement in that all required communications can be achieved by a small number of calls to standard global routing operations.     

Interactive graphic cad for tension structures

This paper reviews the development and application of an interactive CAD system for the form-finding, load analysis and patterning of tensile coated fabric membrane structures. Particular emphasis is given to the integration of all design aspects ranging from form visualization to the production of fabrication patterns within the single CAD system.
