The US Army Research Lab and the Knowledge Engineering Group of the US Army Ordnance Center and School (Aberdeen Proving Grounds, Md.) have developed a visual expert system for diagnostics of the Ml tank's turbine engine. TED (Turbine Engine Diagnostics) is currently delivered on a color laptop PC one support level behind the front lines. Pictures of the engine and graphical representations of the diagnostic process prompt novice and experienced Army mechanics for input or action as they are guided by TED through the correct maintenance procedures. The UKbased Tyne and Wear Development Corp. is developing a virtual reality model of the city of Newcastle upon Tyne as part of that city's redevelopment project. A visualization of the East Quayside area, including landscaping, the road network, buildings, and the Tyne Bridge landmark, is being created as a virtual world.
