The results of orthogonal cutting tests on electroplated Nickel-Phosphorus (15% phosphorus) and AISI 52100 bearing steel are presented and compared. For both
Computer-Aided Design (CAD) software vendors are quickly recognizing the tremendous potentia1 of the Internet for connecting distributed tools and users This
Molecular dynamics simulations of the thermal degradation of polymer nanocomposites were performed in an attempt to explain the reduction in the flammability of
A coupled radiation and soot kinetics calculation of laminar methane/air diffusion flame properties is described. Transport equations for mass, momentum
Numerous investigations have attributed laser-induced broadband fluorescence observed in both rich, premixed flames and in diffusion flames to small polycyclic

We describe a simplified scheme for quantum logic with a collection of laser-cooled trapped atomic ions. Building on the scheme of Cirac and Zoller, we show how
A simple interferometer for matching the wavelengths of tunable lasers is described. Our interferometer uses the angular dispersion of a diffraction grating at
An apparatus has been designed, built, and extensivley tested for making short-duration autoignition temperature measurements of hydrocarbon fuels under
