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 systematic upgrade of a two-phase (gas/particle) missile propulsive Navier-Stokes code, CRAFT, to simulate the three-phase combustive processes occurring in rocket combustion chambers and nozzles is proposed. Preliminary emphasis is on upgrades that will improve the ability to analyze combustion processes in the secondary combustion chamber of ducted rocket engines (DRE). This will involve i ...

Decision Science Associates, Inc. (DSA) proposes to design and prototype an automated decision aid for the assessment of pre-flight risk by Army rotorcraft pilots. This aid will support the rapid assessment of risk based on readily available information. Phase I consists of 4 tasks. In Task 1 we will identify sources of information and determine the critical predictive factors and the types of dat ...

Frog Embryo Teratogenesis Assay: Xenopus (FETAX) is a 96-h, whole-embryo bioassay designed to detect potential developmental toxicants. The primary goal of this research is to improve the predictability and increase the overall utility of FETAX as a screen for developmental toxicants that pose a hazard to human health. Since Xenopus laevis embryos lack mixed-fliriction oxidase metabolism (cytoch ...

Polymeric reverse osmosis membranes are widely used for water and wastewater purification. However, their lack of chemical and especially oxidant (chlorine, oxone) stability, susceptibility to fouling, poor storage/shelf life, and a variety of other disadvantages has limited their effectiveness. By comparison, ceramic membranes display a number of materials advantages over polymeric. Of particu ...

Unmanned Aerial Vehicles (UAVs) offer a lower risk and lower cost platform for the use of an Ultra Wide Band (UWE) Synthetic Aperture Radar (SAR) system for the detection of ground targets concealed by foliage. Given the size, weight, and power restrictions of a UAV, an impulse radar is an attractive radar system alternative because it offers a lighter and lower cost solution than a traditional c ...

A concept for a Soldier's IM Eye-Voice Interface (SHEVI) is proposed as an ideal technology to provide hands-off control of head mounted display information. SHEVI builds on earlier research performed by the proposed research team which demonstrated the feasibility of versatile discrete and continuous control by combining eye-control and voice-control techniques. SHEVI addresses the extension o ...
