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 ...

This project applies a combination of Artificial Neural Networks (ANN), Genetic Algorithms (GA), and CAD software to the problem of optimum armor design. Previous work for TACOM has established the efficacy of ANN/GA as applied to the problem of 1-D armor design. This new work will extend the concept to full 3-D vehicle geometries (CAD models). The CAD part of the code will handle the 3D data d ...

3-D visualization of multiple RF fields requires innovative display techniques to overcome a number of technical challenges, including surface polygon reduction for increased graphics speed, and discrimination of multiple overlapping surfaces. The innovation in the present proposal derives from the PI's recent development of a 3-D tactical display for the Navy in which the interaction of sonar ac ...

RIA scientists have developed a numerical scheme for the detection and classification of complicated signals in highly noisy environments (negative SNR). This method performs DIC using nonlinear signal information based on techniques developed from the theory of Chaotic dynamics. Preliminary tests on real-world data sets, recently supplied by Navy personnel, indicate that this method will likely ...

The current market for fast switching frequency sythesizers is growing rapidly. Most synthesizers available today will not meet the stringent requirements for switching quickly, providing spectrally pure RF outputs and minimizing physical size and cost. As part of a current SBIR program, S.T. Research has developed a wideband, fast switching synthesizer, based on the use of broadband phase-locke ...

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 ...

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 ...

The makeup and location of hostile forces can be identified for battlefield surveillance or target acquisition by deploying a network of autonomous acoustic sensors. Each sensor would listen for acoustic emissions from ground vehicle traffic. Such emissions would then be analyzed by pattern recognition algorithms to determine the presence of acoustic signatures characteristic of potentially host ...
