The burning of a horizontal wood slab situated atop an insulating substrate was modeled using three coupled submodels for the gas-phase, wood, and substrate...
Manufacturing evaluation is performed with heuristics that are developed internally by the manufacturing experts in the company. Many of the existing...
Emergence supports creativity in that emergent features can be considered unanticipated or accidental. The body of shape grammar research over the past quarter...
This paper describes an approach toward the use of optimization which is a departure from the traditional role optimization plays in the design process...
Through the use of light forces exerted by near-resonant laser light, chromium atoms are focused as they deposit onto a substrate, forming nanometer-scale...
The appearance of smaller photomask feature sizes, high density patterns, and optical enhancements such as phase shifters and OPC features, and the increasing...
Increasing shop floor efficiency through scheduling has become one of the major concerns of manufacturing companies. Two of the problems that manufacturers have...
