The overall abjective of this proposed project is the development of detailed definitions for the interfaces defined by the ABBET architecture. Signal models wil developed based upon the C/ATLAS set of signal nouns. A Test Foundation Framework (TFF) will be implemented to demonstrate the ability of test program or test program component transfer across multiple test platforms. This phase also w ...

Research is currently underway to produce guidelines for the development of mission and safety critical systems implemented in Ada 95. This research will analyze whether certain features of Ada 95 should be included or excluded from a critical application. To be of practical value such an analysis will require specific tool support. The Ada Semantic Interface Specification (ASIS) defines a ...

Tunnel ventilation is an effective means of protecting and enhancing the productivity of livestock (especially swine and egg layers) in large scale confinement barns. The capital and operating costs for these fan installations typically represents a significant fraction of the total costs to the livestock producer. The Phase I research program has shown that significant improvements (ca. 40 perce ...

The development of control laws for control of UCAVs in formation requires knowledge of the complete multivehicle dynamical system. This Phase I effort focuses on the design and development of simulation models for multiUCAV situations. During the primary work phase of this effort, a limited wind-tunnel entry in the Langley Full-Scale Wind Tunnel will be performed to demonstrate the ability to m ...

We propose to investigate the use of Adaptive Vulnerability Analysis (being developed under DARPA contract number F30602-95-C-0282) for analysis of Java applets and applications. Java - a platform-independent, Internet-savvy programming language - has found widespread acceptance and has been adopted for use in critical defense information systems such as the GCCS. It is essential to develop and ...

The development of actuators suitable for boundary-layer separation control is proposed. The Phase I effort focuses on the analysis, design, fabrication, and benchtop testing of prototype systems. The actuators will generate disturbances that are large enough to significantly influence the performance of a high-lift system but will be energy efficient and small enough so that multiple actuators ...

We will demonstrate an advanced audio interface for reliable automatic speech recognition (ASR) and other speech systems in dynamic, noisy environments. Our approach uses an innovative, high performance, multi-stage noise removal front-end, that can be integrated with a variety of final speech applications. We will demonstrate end-to-end performance from integrating this processing with multiple ...

We propose the development of a pIezoelectric pressure transducer to be used in diesel engines for machine health monitoring and inclusion in an engine combustion control system. Reliability, accuracy. and affordability are the focus of this research since these issues remain the most difficult to overcome for the development of a cost effective pressure transducer. Manutacturing costs of $5.00 ...
