We investigate the development of a secure fuselet runtime environment built on a foundation of aspect-oriented web services. Aspect-oriented techniques enable the modularization of crosscutting concerns such as remote access, security, and monitoring using code instrumentation. We compose aspect-oriented instrumentation with web service technologies in a noninvasive and orthogonal manner, and lev ...

Based on the success of our Phase I feasibility research, we propose to continue the project for the automated objective speech intelligibility assessment system. It consists of a pair of head and torso simulators placed at the same distance as typical face-to-face communication, a power amplifier, a laptop computer, a speech recognizer, and console software. The simulator has acoustic properties ...

Advanced space-borne infrared detectors require cooling at temperatures near 10 K. Cooling loads for these detectors will range from 0.25 W to 1.0 W at 10 K, with additional loads at higher temperatures. A multistage cooler, capable of cooling multiple loads, will offer large potential gains in system efficiency and weight. Turbomachine-based Brayton cryocoolers are ideal candidates for these m ...

SIDE SCAN SONAR HAS DEVELOPED TO THE POINT WHERE IT IS NOW AN ACCEPTED PART OF HYDROGRAPHIC CHARTING PROJECTS, AS WELL AS A BROAD RANGE OF OCEAN SEARCH AND SURVEY APPLICATIONS. ONE LIMITATION ON ITS UTILITY, HOWEVER, IS THE REQUIREMENT TO OPERATE THE SYSTEM AT RELATIVELY LOW SPEEDS (5 KNOTS OR LOR LESS) IN ORDER TO ACQUIRE HIGH-QUALITY DATA. ANY INCREASEIN VESSEL SPEED CAPABILITY WOULD RESULT IN G ...

A need exists to develop cost effective and reliable submersible cage technology for exposed aquaculture. The team assembled as part of this SBIR incorporates JPS Industries, Great Bay Aquafarms and the University of New Hampshire. In Phase I, a design will be developed based on concepts known to work in the industry. Concepts to be investigated include a cage constructed around HDPE pipe, with ...

In recent years, as relevant technologies have advanced, there has been renewed interest at the Missile Defense Agency in Boost Phase Intercept (BPI). One of the key capabilities necessary for a viable BPI system is an Early Launch Detection & Tracking (ELDT) system. In order to provide enough time for an intercept to be made during its ascent phase, the target must be detected and characterized ...

The projected cost for the Mentis Sciences, Inc., (MSI) prototype PAC3 radome is 1/6th of the total cost of the present system. A Pareto analysis of the current MSI process indicates that the two largest costs in radome production are the direct labor associated with fabrication and the cost of the raw materials. In Phase I MSI demonstrated that COTS paint spraying technology reduced the direct ...

Solid State Scientific Corporation proposes an triangular barrier photodiode (TBPD) detector for use on a dual mode sensor. The TBPD will function as a passive low-light visible-SWIR imager at long range and as a 3-D LADAR sensor at short range. The TBPD has the advantage of increased optical gain with decreased incident power, making it very attractive for applications with weak target signals, ...

The main objective will be to optimize and improve the reliability and reduce the overall system weight for the numerous currently pneumatically actuated flight qualified valves. The Phase I formulations of lightweight and chemical resistant composites will be optimized for performance and ease of fabrication into valve components. Prototype valves will be fabricated and tested. Extensive te ...
