Dual, Incorporated proposes to investigate the development of an exciting, innovative educational system, called the Virtual Experiential Training System (VETS). VETS will use emerging mult- sensory interaction, 3D rendering, and other simulation technologies to enable an individual to become personally involved in a participatory learning experience. The system's pilot learning experience is th ...

EAST proposes to investigate the feasibility of building a comprehensive learning system called, METAMATH, for improving the mathematical literacy of adults using CD-ROM technology. Having researched metacognition applications for military training and education, EAST is proposing a software architecture that combines the recommendations of the National Council of Teachers of Mathematics with 21st ...

The contractor proposes a new approach to underwater imaging that directly converts a two-dimmensional acoustic pressure wave into an electronic requirements fo convential piezo-element arrays. The imager relies on the piezo-birefringent properties of a nematic liquid crystal panel that serves as both sensor and display. The capability of nematic liquid crystals has been established and publishe ...

Acoustic signals provide characteristic information about vehicles. However, those characteristics vary with engine speed, load, range, gearing, and acoustic environment. The complexity of these variations makes standard parametric classifiers either excessively tedious to construct or unreliable under off-nominal conditions. A new method of classifier construction, Generalized Potential Functi ...

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 ...

The study of the combustion of solid propellants is important for the development of more powerful and efficient solid rockets. The constituents of the propellant mixture and the manner in which they are mixed determines burn rates, mass flux, and in the end thrust and Isp. To make further progress in understanding the combustion mechanisms of propellant mixtures, experimental measurements o ...
