An approach to object identification and sensor fusion of images is proposed. Preprocessing techniques which perform a useful and computationally efficient transformation on the image will be considered. Once the image has been transformed to a more efficient format, mathematical morphology and neural networks are proposed to address the issues of edge detection, identification, sensor fusion and ...

We will use an innovative neural network algorithm to perdict and control National Aero-Space Plane(NASP) unstarts at the earliest possible moment. Unstarts present a design challenge to hypersonic aircraft. An unstart occurs when the pressure at the aft end of the engine flow path reaches a critical level. This overpressure causes a "choking" of the air flow. The flow tends to spill around the in ...

Jet engine test cells are faced with meeting regulations related to NOx emissions and opacity. Based upon reported research results, it appears that the Pulse Induced Plasma Chemical Process (PPCP) could be effectively applied to jet engine test cells for the control of NOx. The process provides high efficiency NOx removal at relatively low temperature without the need for NH3 injection. PPCP can ...

A STEP TOWARD BEING NUMBER ONE IN MATHEMATICS AND SCIENCE EDUCATION BY THE YEAR 2000 (AMERICA 2000 GOAL) AND MAINTAINING REASONABLE SCHOOL BUDGETS CAN BE MADE BY INTRODUCING A LOW COST SYSTEM WHICH WILL BRING THE STATE-OF-THE-ART TECHNOLOGY INTO THE HIGH SCHOOL LABORATORY. THE PLANNED LABORATORY WORKSTATION ADDRESSES THIS NEED, BY TAKING THE STATE OF THE ART TOOLS AVAILABLE FOR RESEARCHERS AND INT ...

STATIONARY SOURCES IN THE U.S. EMIT ABOUT ONE MILLION KG OF MERCURY INTO THE ATMOSPHERE ANNUALLY. MAJOR SOURCES OF THESE EMISSONS ARE FOSIL FUEL COMBUSTIONFACILITIES ANE MUNICIPAL SOLID WASTE INCINERATORS. MUCH WORK IS BEING DONE BY DOE AND INDUSTRY TO CHARACTERIZE THESE EMISSIONS AND TO DEVELOP EFFECTIVE CONTROL MEASURES. CONTINUOUS EMISSIONS MONITORS (CEMS) FOR MERCURY WILL PLAY A SIGNIFCANT ROL ...

The development of a simple, reliable, and easily operated system to detect and measure airborne lead (Pb) to trace levels is the subject of the Phase I effort. Lead is toxic to humans at very low levels and is ingested easily by breathing air in which elemental Pb or compounds of this element are dispersed. In firing ranges there is an opportunity for shooters and range personnel to be exposed to ...

IMPROVED FABRIC FILTER PERFORMANCE FOR BOTH THE COLLECTION OF FINE PARTICULATE MATTER (PARTICLES LESS THAN 10 MICRONS) AND TOXIC METAL EMISSIONS FROM FLUEGASES IS IMPORTANT BECAUSE MOST OF THE TOXIC METALS ARE CONCENTRATED IN THIS SIZE RANGE, FINE PARTICLES ARE RESPIRABLE AND THEREFORE POSE A HEALTH RISK, AND FINE PARTICLES ARE EFFECTIVE LIGHT SCATTERERS AND LEAD TO HIGH OPACITY LEVELS. IT IS PLAN ...

Dependability is an increasingly critical characteristic of the Navy's mission critical computer systems. These systems must be maintained in a state of readiness to support critical mission functions, and must be able to perform these functions correctly despite the presence of faults in system hardware and software components, and in the environments in which the systems operate. Automated tools ...
