DDL OMNI Engineering proposes to design a secure system for the continuous, real time acoustic measurement of towed array position relative to the host submarine. By using focused transmit and receive assemblies, pseudo- random spread broadband signals, and relatively high carrier frequency, the transmission level will be minimized so as to be virtually undetectable by a non-dedicated system ...

Composite materials find increasing importance as structural materials for modern lightweight and low cost aircraft. Structures using composite materials essentially rely on the integrity of adhesive bonds for their structural stability. A major limitation in employing composites in critical structures is that the existing methods of testing the integrity of structures are not adequate to a ...

A DOT IMMUNOASSAY FOR THE DETECTION OF ACROSOME REACTION OF HUMAN SPERM WILL BE DEVELOPED FOR USE IN THE DETECTION OF MALE INFERTILITY. SCREENING TESTS FOR THE DETERMINATION OF THE CAUSES OF INFERTILITY AND SCREENING SEMEN SAMPLES FOR SPERM BANKING HAVE BECOME MAJOR RESPONSIBILITIES OF FERTILITY CLINICS. HOWEVER, NO SIMPLE METHOD CURRENTLY EXISTS FOR THE DETERMINATION OF THE FUNCTIONAL ABILITY OF ...

This project addresses two problems of environmental and economic importance to New Mexico.The first problem is the value-added utilization of pecan shells, and agricultural waste from oneof New Mexico's most important crops. The second problem is the need to remove metal andorganic contaminants of environmental concern from wastewater produced by some of NewMexico's economically important indust ...

Active noise reduction (ANR) headsets have found a market niche in the hearing protection industry, thereby validating the technology of active noise control for personal applications. This Phase I project will seek to extend the application of personal ANR systems to include specialized headphones which can successfully evaluate hearing acuity in typical clinical environments. To ensure a succe ...

The statistical software program "Resampling Stats" will be modified to serve as a teaching instrument, with emphasis on students in colleges of education - our future teachers. The American Statistical Association (ASA) and the National Council of Teachers of Mathematics (NCRM) identify probability and statistics as vital subjects for high school students. Unfortunately, education students too o ...

This project proposes preliminary investigations to prove the feasibility of four techniques for improving Adaptive Beamforming performance in littoral environments. Emphasis is placed on tradeoffs between algorithm efficiency and performance. The littoral acoustic environment is characterized by near and far field targets and dense dynamic near and far field directional interference at man ...

Amron and its subcontractor BBN propose to show the feasibility of a broadband time-domain adaptive beamformer (ABF) to suppress uncorrelated narrowband sources and multipaths from correlated impulsive sources. The work is motivated by political developments which have emphasized warfare in littoral areas, where a key problem facing active sonar is scattering from topographic features. Activ ...

Fiber & Sensor Technologies (F&S), teaming with Virginia Tech, proposes to develop an adaptive control system for cure of thermoset resins during manufacture and repair of polymer matrix composites. Leveraging DOD-sponsored development of fiber optic cure monitor sensors, F&S will develop an embeddable "sensor string" by multi-plexing pressure, temperature, and viscosity sensors on a single optic ...

This project is dedicated to the development of an adaptive network security management tool that is analogous to implementing and incident/response paring mechanism on top of a universal remote control facility for a variety of network and security tools, network types and operating systems. Our proposed approach to accomplishing this is to integrate and agent architecture with a Case-Based Reas ...
