Scheduling is a complex, NP-hard problem that challenges the use of any single solution technique. In Phase I, we built a model that uses our multi-technique Quantum Leap Problem Solving Engine to solve a representative but simplified version of the AirForce Satellite Control Network (AFSCN) contact scheduling problem. The system demonstrated that it could schedule the hundreds (500 to 600) of t ...

Active sonar systems face a significant declutteringproblem especially when operating in shallow water. In futuremulti-static, multi-receiver search missions, the number of alertsis expected to increase dramatically. Tactical scenarios presenta further complication because response time is critical and, as aresult, classification in the fewest number of pings is cruciallyimportant. Historically ...

The interaction of radio frequency electromagnetic energy with the human body is best computed with finite difference methods. For good accuracy, especially at higher frequencies, the human body description requires many millions of individual voxels. Thevoxels fill the entire volume of the body and describe both the outer surface and interior organs of the body. Making one detailed voxel mesh o ...

Stress monitoring in composite materials is a difficult but necessary endeavor. It is required for testing to compare measurements with modeling predictions as well as to monitor flexing and vibration under load. Presently, there are only a limitednumber f methods to measure strains that are suitable for embedding in a composite material and all are either expensive or complex. This proposal is ...

We propose to continue our Phase I effort in Phase II by implementing the GPS anti-jam attitude-capable adaptive antenna technology into a C/A-code prototype and a P-code software development toolkit with an extension to the new M-code. The hardwareprototype will consist of an array antenna, RF front-ends, a PC-based data acquisition system, a PC-hosted DSP system, power supply, and other auxiliar ...

The recognized risks associated with the introduction of new material and oil formulations for propulsion system bearings and gears have created a crisis with respect to urgent needs for increased load, speed and temperature. Conventional test methods formaterials and oils have insufficient linkage to service performance and mechanisms that control life and durability. The recognition of the cur ...

ASTROPOWER PROPOSES TO DEVELOP A LIGHTWEIGHT, HIGH EFFICIENCY, MONOLITHICALLY INTERCONNECTED THIN SILICON SOLAR CELL ARRAY. THE ARRAY INCORPORATES AN INNOVATIVE TECHNIQUE TO ACHIEVE ELECTRICAL ISOLATION AND INTERCONNECTION OF THE ARRAY ELEMENTS. A MONOLITHICALLY INTERCONNECTED ARRAY TECHNOLOGY OFFERS REDUCED COST AND COMPLEXITY AS WELL AS INCREASED RELIABILITY AND YIELD COMPARED TO CONVENTIONAL SO ...

Piezoelectric ceramic sensors and multilayer actuators with enhanced performance are required for applications in health monitoring and active vibration control in space structures. The technology of producing highly reactive submicron perovskite (ABO3) materials known as "reactive calcination" is proposed. Enhanced performance due to processing at temperature

THIS DOCUMENT IS A TECHNICAL PROPOSAL TO DEVELOP AN ELECTRONIC OPTICAL VECTOR SCORING SYSTEM (EOVSS) FOR ACCURATELY MEASURING THE TRAJECTORY OF A MISSILE, RELATIVE TO A TARGET DURING THE FINAL PHASE OF A MISSILE ATTACK ON A TARGET. THE PROPOSED EOVSS SYSTEM EMPLOYS MULTIPLE TV CAMERAS ON THE TARGET AIRCRAFT. AN AIRBORNE VIDEO SYSTEM SUTOMATICALLY SELECTS THAT CAMERA(S) VIEWING AND ATTACKING MISSIL ...

We propose to develop an imroved analytical model for predicting the velocity and direction of fragments projected by an explosive warhead. The model will account for the metal acceleration history, unsteady effects, curvature, internal voids, and end effects (explosive pressure release). The model will be validated by comparisons with experimental data and hydrocode corruptions .
