A THREE-DIMENSIONAL, NONHYDROSTATIC CLOUD MODEL IS USED AS A TOOL TO INVESTIGATE THE PROBLEM OF THUNDERSTORM INITIATION. OPERATIONAL NUMERICAL MODELS DO A POOR JOB OF PREDICTING THE GEOGRAPHIC DISTRIBUTION OF CONVECTIVE ACTIVITY, ESPECIALLY DURING THE WARM SEASON, WHEN THE LARGE SCALE CIRCULATION IS RELATIVELY WEAK. THE CUMULUS PARAMETERIZATION SCHEMES USED IN CURRENT MESO-BETA-SCALE RESEARCH MODE ...

MicroFab Research (MFR, Inc.) proposes to apply the techniques of micromachining to aid in the fabrication of millimeter wave components, thereby reducing manufacturing expenses. Many microwave applications such as radar and communication systems would be improved by shifting to higher frequencies, provided new lower cost manufacturing techniques can be found. A manufacturing technique is presen ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

We propose a standard software system that enables a natural, intuitive interface between computer operators and their data, for improving and increasing the capability of Air Force C4I systems. Specifically, the tasks addressed here are: (1) multi-dimensional map displays for interactive planning tools; (2) new tools for modernization of base-level business processes; and (3) improved human int ...

PREVIOUS RESEARCH EFFORTS CONCERNING THE COGNITIVE PERFORMANCE OF THE MEMBERS OF COMMAND AND CONTROL (C2) TEAMS IN DISTRIBUTED, COMPUTER-MEDIATED SYSTEMS HAVE FOCUSED ON MODIFICATIONS OF SYSTEM DESIGN TO ENHANCE COGNITIVE PERFORMANCE. MYSTECH PROPOSES A COMPLEMENTARY EFFORT THAT FOCUSES ON INNOVATIVE C2 TEAM TRAINING METHODS TO IMPROVE COGNITIVE PERFORMANCE. THE RESEARCH WILL FOCUS ON A SPECIFIC C ...

METHODS OF INTEGRATING ANALYTICAL AND EXPERIMENTAL TECHNIQUES TO PREDICT ELECTRONIC DEVICE RESPONSE TO VIBRATION AND SHOCK LOADINGS ARE PROPOSED. UNIQUE NONINTRUSIVE EXPERIMENTAL TECHNIQUES, COUPLED WITH ADVANCED DIGITAL SIGNAL PROCESSING ALGORITHMS, WILL BE USED TO VERIFY FINITE ELEMENT MODEL INPUT DATA, MODELING ASSUMPTIONS, BOUNDARY CONDITIONS, AND TO DETERMINE MATERIAL PROPERTIES SUCH AS DAMPI ...

Knowledge based methods have the potential to offer high performance solutions to a wide variety of problems. However, the development of large scale knowledge bases (KBs) and their effective application to problems have so far proved to be more expensive and less feasible than other competing methods such as statistical methods or weak search techniques. There is an immediate and critical need to ...

DIAGNOSTx Technologies proposes to develop a PC-based instrument for the clinical evaluation of peripheral and central hearing deficits, which will allow audiometric, otoacoustic emissions, evoked-potentials and immittance testing. The integrated system will be capable of assessing hearing sensitivity for speech and pure tones, of evaluating the integrity outer hair cells and auditory central ner ...

The project goal is to produce an algorithm for synthesizing auditory distance which will be accurately perceived with little or no learning required. The algorithm could be added to an existing AF 30D audio system which uses headphones in a noise-reducing helmet. The approach is to combine very accurate recently developed atmospheric modeling with head-related transfer functions (HR ...
