Ganuna (7)-ray lenses are an advanced technology currently under development at Argonne National Laboratory for arms control application. The purpose of this proposal is to address whether y-ray lens technology can enable an improved system for imaging radioactive isotopes in patients. In nuclear medicine, it is often desirable to generate a y-ray image that shows the exact areas where an emitting ...

AcuSoft proposes to research and develop a database conversion tool based on the Synthetic Environment Data Representation and Interchange Specification (SEDRIS) to maximize the reusability and interchangeability of existing and future USSOCOM database. In the proposed PHASE I effort, we will investigate SEDRIS technology and develop a functioning prototype tools to demonstrate the ability to imp ...

DARPA has identified a need for Engineering Decision Support computer tools for multi-disciplinary design teams involved in the specification, design and development of complex electro-mechanical products. During the product specification process, key decisions are made which define the product evolution and ultimately determine the product's acceptance by the customer. Current design systems ...

We propose a radically innovative approach to the problem of multiple access communication which promises to revolutionize the modern communication industry by dramatically increasing network throughput. Our approach is based upon two major novel components: (i) hybrid time-frequency allication of communication channel resources, and(ii) non-orthogonal, i.e., overlaping, multiplexed signals. Toge ...

The adaptive single user receiver invented at AF LAB has been shown to suppress multiuser and certain forms of narrow-band interference in adecision directed mode during the entire transmission, without requiring knowledge of other users spreading codes, timing or phase information in direct-sequence proposal, we investigate the use of our single user receiver for secure communications as required ...

The dolphin has a unique sonar capability by which it produces high-frequency clicks. The dolphin is able to vary both the frequency content and the repetition rate of the echolocation clicks. The goal of the combined Phase I and Phase II project is to model the dolphin sonar and to design, construct, and build a sonar system capable of mimicking the dolphin's behavior and ultimately to use this d ...

An open problem confronting Uninhabited Tactical Aircraft (UTA) is the control concept for their successful operation in combat. Unlike reconnaissance UAVs, it will not be practical to operate UTAs with fully pre-programmed missions nor will it be possible to continuosly fly with them from remote cockpits. A new control paradigm is needed. One that supports a full range of intervention from dir ...

A novel beamforming network is proposed to electronically scan two independent beams in a conformal phase array. The beamformer utilizes ferroelectric materials in the RF distribution network to control the amplitudes and phases of the array element excitations. One beamformer board is required for each beam and four low power DC voltages per beamformer are needed to achieve total hemispherical ...
