Project objectives briefly described: i. Improve accuracy of measurement for cheating examinees by using a scoring method that takes account of the credibility of the examinee's patterm of wrong answers. ii. Provide an adjunct to on-line calibration that would assist in timing the replacement of items. iii. Identify test sites and recruiters that are associated with high rates of item compromis ...

INNOVATIVE TECHNIQUES ARE PROPOSED FOR INVESTIGATION IN A PHASE I EFFORT TO DETERMINE PASSIVE RF SURVEILLANCE AND TARGETING SENSORS AND ASSOCIATED METHODOLOGY FOR PERFORMING RAPID AND ACCURATE MEASUREMENTS OF RANGE/LOCATION OF OTH THREAT RF EMITTERS. THE ESSENTIAL PHYSICAL CONSTRAINTS TO BE OBSERVED ARE SENSOR COMPATIBILITYWITH, AND PORTABILITY OF THE ASSOCIATED RANGE DETERMINATION/ PROCESSING EQU ...

Microscopic measurement of surface topography is a continuing need in microfabrication technology and materials research. The aim of this research is to adapt the scanning electron microscope (SEM) to the quantitative measurement of a wide range of surface structures. The SEM is a widely used measurement tool in materials science and semiconductor fabrication. The SEM's strength is that it prov ...

Marine storms strongly affect operations at sea, both DoD and commercial. The DMSP SSM/I clearly depicts certain features of marine storms. Improved depiction of these storms will aid nowcasting in support of execution.of operations at sea and fore- casting of the evolution of these storms in support of planning. However, SSM/I data as well as many other satellite data have only small impacts on t ...

Smart IR technology has advanced at a rapid pace over the last two decades, pushed along by primarily defense-related requirements. This includes such breakthroughs as Acousto-Optic Tunable Filters and microbolometer detector arrays. Coupled with the continuing growth in microprocessor power, this promises to make a new generation of fast, cheap and reliable infrared (IR) fire detectors possible ...

The introduction of a whole new class of transform methods, notably the wavelet transforms, which permit decomposition of observed phenomena into different physical scales and the computational leverage provided by multiscale image processing tech- niques, when applied to multisensor Lmage data, promises to increase the sensitivity and reliability of Lmage processing systems in several application ...

ALPHATECH has recently developed an integrated software environment for developing and testing prototype fault detection and identification (FDI) systems. It has been applied with excellent results (zero false and missed alarms, with 4% probability of deferral to the next decision time) to helicopter gearbox test-stand accelerometer data. The front-end of our environment extracts novel feature set ...

This Phase I SBIR proposal is aimed at developing and assessing the feasibility of Image Processing Techniques to distinguish between submarine and non-submarine in Active Sonar Echoes. Image Processing Techniques have proven to be highly effective in detecting objects in cluttered backgrounds using other sensors such as Synthetic Aperture Radar, Infrared Sensors, and Lasers. The highly reverberan ...
