As the potential of the High Level Architecture (HLA) is realized, the size, scope, and frequency of federations will grow, and as they do, so will the expense of the manual federation planning, execution, monitoring, and analysis process. The basis for an automated approach to exercise execution and monitoring is the Execution Plan developed during the federation planning phase and containing Fe ...

It is well-recognized that it is difficult to effectively retrieve detailed technical knowledge from a subject matter expert (S&M) to use in an instructional system. The goal of this proposal is to provide a system to enhance the Navy's ability to retrieve this knowledge in order to augment the development of courseware, to provide additional information to instructors, and to identify and cap ...

The objective of this project is to design a new large caliber naval gun to fit in a relatively small volume within a ship and yet be capable of firing ranges considerably greater than are presently available from equal caliber guns and ammunition. This gun will have a very short recoil whose greater recoil forces will be passed directly to major load bearing structure near the ship's ke ...

The mechanical characteristics of advanced composite materials are strongly affected by physical parameters such as ply orientation, thickness of the layers, and homogeneity of the fibers. Although proper material integrity is critical for performance, many factors influencing mechanical properties cannot be detected by visual inspection Small anomalies or incipient degradations including d ...

A ROBOTIC POSITIONER WILL BE DEVELOPED FOR HANDLING AND CHANGING DEVICES TO BE TESTED (DUTS) IN HAZARDOUS RADIATION ENVIRONMENTS SUCH AS THAT FOUND INSIDE THE TEST CELL OF THE BROOKHAVEN NATION LABORATORY PROTON ACCELERATOR. PRESENTLY, PERSONNEL SAFETY INDICATES A LONG "COOLING" TIME BEFORE TEST FIXTURES CAN BE ACCESSED. THIS RESULTS IN LOWERED FACILITY USEFULNESS, INCREASED REAL FACILITY COSTS AN ...

We propose a new method for adaptive nonstationary spectral estimation and harmonic analysis for stepped-frequency inverse synthetic aperture radar (ISAR) imaging. The essential idea is to construct a set of orthogonal windows that have little spectral leakage and use each of these windows to create an independent spectral estimate. A data dependent and frequency dependent weighted average ...

Attachment areas in the regions of rotating components of gas turbine engines degrade due to fretting wear and fatigue. Plasma sprayed coatings are often used to protect these regions. A thin, dense, Ti(C, N) composite coating based on sol-gel process is proposed. The simple, cost-effective sol-gel process will coat complex shapes and will provide superior performance against fretting wear. Di ...

Computing technology (as well as control and display technology) is rapidly becoming more powerful, miniaturized and wearable. These trends will allow Navy personnel to be increasingly mobile, not tethered to hardwired console and computer systems. In conjunction with wearable display systems, wireless LANs, and alternative control mechanisms (such as voice recognition), system operators may, ...
