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 objective of this basic research is to design and develop a low-frequency, ultra-wide band (UWE) antenna. Such an antenna combined with a pulse-generating radar system would be capable of penetrating and detecting targets through foliage, ice, snow, and even earth. Development of appropriate radar systems is state-of-the-art except for the antenna, which requires a breakthrough in technology ...

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 ...

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 ...

The proposed Phase I project is the design and development of a wireless comprehensive sensor system for structural health assessment and monitoring. The final goal will be a system consisting of sensor modules or packages which can be permanently placed at the selected critical locations within a structure and which are powered and communicate wirelessly with a master station. The sensor module ...

Detection of natural, variable objects requires general features that can be extracted from any image. Human vision is capable of segmenting images and recognizing objects in radiographs despite the summation of all objects in the inspection volume in the image plane. Thus, the features important in human perception provide a guide for automatic image processing. The initial features selected f ...

Natural materials such as tooth, bone or shell consist of a high volume fraction of ceramic grains coated by thin layers of proteinaceous film. The ceramic grains are grown in situ in a pre-formed organic polymer matrix. The organic portion provides high toughness, while the ceramic component provides stiffness. This unique microstructure allows for mechanical properties superior to man-made ce ...

Military scout vehicles and commercial sports utility vehicles share the common need for advanced suspension/drive systems that offer robustness over widely varying terrain. The ultimate system for handling, ride isolation, and stability control would incorporate high efficiency electric motors independently driving the four wheels, with one on-board high-level computer for controlling the active ...
