Engineering design is characterized by a high level of imprecision, vague parameters, and ill-defined relationships. In design, imprecision reduction must occur to arrive at a final product specification. Few design systems exist for adequately

Engineering design is characterized by a high level of imprecision, vague parameters, and ill-defined relationships. In design, imprecision reduction must occur to arrive at a final product specification. Few design systems exist for adequately
The elimination of new production of halon 1301 has forced the manufacturers, owners, and users of aircraft to search for an alternative. The program described here developed performance screens for candidate agents as a means to identify the best
The passage of the 2018 Farm Bill has led to an estimated value of $824M for hemp production in the United States (US) in 2021 with an approximately 76% of it focused on floral hemp that is used to produce hemp-derived finished products such as smokable
… lead to re-design that is more reliable, and to improved manufacturing. The goal of accurate performance and lifetime … postulated to be the key tool for optimizing fabrication/manufacturing and controlling reliability of nanomaterials. …
Fuel cells are emerging as one of the most promising technologies for meeting the nation s energy needs. Fuel cell efficiencies, approaching 60 percent, are nearly twice as efficient as conventional power plants. Fuel cells are environmentally clean and
The BEES (Building for Environmental and Economic Sustainability) tool implements a rational, systematic technique for selecting cost-effective green building products. The technique is based on consensus standards and designed to be practical, flexible

The national and economic security of the United States (U.S.) is dependent upon the reliable functioning of the nation's critical infrastructure. Positioning, Navigation, and Timing (PNT) services are widely deployed throughout this infrastructure. In a
During the track accessing mode ofa hard disk drive, theflying height of the slider over thedisk surface becomes smaller and smaller as the demand in data storage density increases. As aresult, the propensity of glide avalanche is bound to increase when

The complex void microstructure of thermally sprayed deposits may be approximated by three major void syste(interlamellar pores, intralamellar cracks, and volumetric globular voids), each with different volume fractions,anisotropies, sizes and shapes. This
Robots can perform various typed of automated movements in workspace. In recent years, robot applications have been expanded to a much wider scope, including robot machining, robot assembly, robot 3D printing, robot inspection, etc. Many of these
