One of the biggest problems faced by both military and non-military personnel in planning and conducting Operations Other Than War (OOTW) and Law Enforcement (LE) is a lack of cultural awareness. A lack of cultural awareness in OOTW causes misplanning and misinterpretation in the areas of economics, politics, religion, and historical events. The objective of the proposed work is to produce a des ...

THIS PROPOSAL PRESENTS AN INNOVATIVE APPROACH TO DETERMINING THE PROPAGATION PATH OF ACOUSTIC DATA RECEIVED BY A THIN LINE TOWED ARRAY. WE MAKE USE OF THE LATEST DEVELOPMENTS IN SEAFLOOR ACOUSTIC MODELING CAPABILITY AS WELL AS EMPLOYING THE EMERGING AND POWERFUL TECHNIQUES ASSOCIATED WITH ARTIFICAL NEURAL NETWORKS. THE PROPOSED NEURAL NETWORKS WILL BE DESIGNED TO IDENTIFY THE PATH OF PROPAGATION F ...

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 ...

THE PROBLEMS OF ATTENUATING DUCTED NOISE AND DISTRIBUTED NOISE ARE ADDRESSED USING ACTIVE NOISE CANCELLATION TECHNIQUES. FOR DUCTED NOISE, A COMBINATION OF COMMERCIAL ANC EQUIPMENT WITH LOW PRESSURE DROP MUFFLERS IN AN SVS PROPRIETARY CONFIGURATION WILL BE EXAMINED. COST AND PERFORMANCE TRADES BETWEEN THE ACTIVE CONFIGURATION AND PASSIVE MUFFLERS WILL BE MADE AND AN EXPERIMENT WILL BE DESIGNED FOR ...

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 ...

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 ...

Mountain Wave, Inc. proposes to investigate the development of an automated network security management product that would allow personnel within an Information Technology (IT) organization to combine information from heterogeneous sources into an integrated application that captures business processes and automates tasks to "prevent" potential security violations. This product will: be "extensib ...
