In this case a mechanic engaged by Boylan negligently performed repair work, resulting in an injury to Mrs Sweeney. Since the mechanic was a contractor rather than an employee, Mrs Sweeney was unsuccessful in her action against Boylan. Whil...

Turbine Engine Diagnostics (TED) is a diagnostic expert system to aid the Ml Abrams tank mechanic find and fix problems in the AGT-1500 turbine engine. TED was designed to provide the apprentice mechanic the’ability to diagnose and repair the turbine engine like an expert mechanic. The expert system was designed and built by the U.S. Army Research Laboratory ,I_. \ ~HKLJ and the U.S. Army Ordna...

Game designs often center on the game mechanics— rules governing the logical evolution of the game. We seek to develop an intelligent system that generates computer games. As first steps towards this goal we present a composable and cross-domain representation for game mechanics that draws from AI planning action representations. We use a constraint solver to generate mechanics subject to desig...

A high risk for the development of diffuse pleural mesothelioma is known to exist in various occupational settings associated with the use of asbestos.' Although a serious hazard has been recognised among asbestos miners, millers, and shipyard workers, recent evidence suggests that a high risk of mesothelioma may exist among occupational groups previously thought to be at low risk for developin...

TED was designed to provide the apprentice mechanic with the ability to diagnose and repair the turbine engine like an expert mechanic. The expert system was designed and built by the U.S. Army Research Laboratory and the U.S. Army Ordnance Center and School. This article discusses the relevan...

Crystalline molecular machines represent an exciting new branch of crystal engineering and materials science with important implications to nanotechnology. Crystalline molecular machines are crystals built with molecules that are structurally programmed to respond collectively to mechanic, electric, magnetic, or photonic stimuli to fulfill specific functions. One of the main challenges in their...
