Statistically sound approaches to making interfrences regarding simulation model validation, rather than reliance upon subjective appeal, are needed. Fundamentally, the question of interest is whether a model reflects reality to the required degree of accuracy. The utility (and hence validity) of a simulation model relies on how well it captures those aspects of the phenonmenon under study that ...

As identified in the SBIR announcement, virtual environment technologyhas found widespread use in the military in applications related to the recreation of a photo realistic display. The SBIR announcement further recognizes that a significant need exists for aids in developing skills for managing complex situations which are best addressed at a more abstract level. The current proposal seeks to ...

Recent cognitive research indicates that military teams operate effectively in high-stress, information-rich environments when they 1) share mental models of the battlefield situation and the team; 2) critique their situation model to develop clear goals for information retrieval; 3) effectively communicate information needs to others; and 4) anticipate and counteract information overload. We pro ...

Inappropriate trust of automation can lead to suboptimal performance, in which the respective capabilities of humans and computers are not effectively exploited. In some cases, over- or under-reliance can lead to catastrophe. The primary objectives of the proposed Phase I work are (1) to develop a systematic general framework for training users of decision aids, with particular attention to the ...

THE CURRENT STATE OF ROBOTIC TECHNOLOGY IS FAR FROM THE GOALOF AUTOMATED INTELLIGENT BEINGS. IN THE INDUSTRIAL SCENARIO WHERE MUCH OF THE CURRENT ROBOT DEVELOPMENT HAS BEEN APPLIEDMOST ROBOTS ARE LITTLE MORE THAN ADVANCED NUMERICAL MACHINES. LIMITED FEEDBACK SENSING AND CONTROL HAVE BEEN IDENTIFIED A A MAJOR LIMITATION OF CURRENT ROBOT TECHNOLOGY.AUTOMATED OR SEMI-AUTOMATED CASUALTY ASSISTANCE AND ...

Successful development of advanced turbine engines will depend heavily upon rapid development of new, reliable, lightweight metal matrix composites (MMC's) having unprecedented high temperature properties. Recent developments in the manufacture of MMC's by vapor deposition methods offer the prospect of producing polyphase microcomposite precursors in the form of continuous monofilaments or thin m ...

A need to control the fugitive emissions of hazardous vapors, volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) has been identified in operations at Army plants and depots. The High Mesa Technologies (HMT)/Coyote Aerospace team proposes to meet this need using proven silent discharge plasma (SDP) techniques, developed by the Electric Power Research Institute and Los Alamos Nat ...

Misacylated transfer RNA's bearing unusual amino acids will be prepared on a preparative scale and employed in in vitro protein biosynthesizing systems to produce polypeptides containing one or more modified amino acids at predetermined positions. The specific goals of the project include (i) determination of the feasibility of preparing misacylated tRNA's on a preparative scale, (ii) assessment o ...
