A novel approach for the development of a lightweight, low-cost, compact, and quick start-up on-board fuel reformer is proposed in this Phase II program. The approach is based on a novel MER¿s technique for the fabrication of multichannel mini-reactors incorporating hydrogen separating membrane. Multichannel mini-reactor shrinks the dimensions through which energy and reactants travel to their ...

This is a Phase 2 proposal to develop an instrument to simultaneously measure particle size, velocity, and concentration in applications characterized by a large size range and high particle concentration. The instrument will be based on the Pulse Displacement Technique whose feasibility was demonstrated during Phase 1. Experiments performed during Phase 1 demonstrated a high accuracy in meas ...

N/A

As flip-chip bonding becomes the predominant standard in the electronics industry, the increased proximity between dice surfaces and packaging materials will require a significant reduction in the latter's alpha particle activity in order to avoid soft errors. Emission rates at or below 0.001 a/cm2/hr are desirable, which is well below the 0.0050 a/cm2/hr capability of today's best detectors. ...

As ever more of industry and commerce moves onto electronic networks, there is a growing appreciation for the usefulness of expressive general models of enterprise activities, such as design and manufacturing. Ontologies are commitments to formal declarative multi-purpose representations with clear semantics that can serve as a solid foundation for such models. While there has been much work ...

SOFTWARE HAS BECOME EXPENSIVE; BY THE YEAR 2000, IT REPORTEDLY WILL BE A 2 TRILLION DOLLAR INDUSTRY WORLDWIDE. TO REDUCE COSTS, IT IS VITAL TO REUSE CODE. OBJECT-ORIENTED (00) LANGUAGES ARE TOUTED TODAY FOR THE EASE WITH WHICH SOFTWARE COMPONENTS WRITTEN IN THEM CAN BE REUSED. DUE TO THIS CHARACTERISTIC (ALONG WITH OTHER BENEFITS FO 00 SOFTWARE), SOFTWARE VENDORS ARE BEGINNING TO WRITE CRITICAL AP ...

DIVER SCIENTIST COMMONLY RELY ON A VARIETY OF INSTRUMENTS TO ACCOMPLISH THEIR MISSION. USING MULTIPLE SPECIALIZED INSTRUMENTS HOWEVER NOT ONLY IS COSTLY, BUT ALSO LIMITS A DIVERS MOBILITY. STILL, MANY CAPABILITIES TAKEN FOR GRANTED BY "TOP-SIDE" FIELD RESEARCHERS, SUCH AS PRECISE NAVIGATION AND COMPUTERIZED RECORD TAKING, REMAIN UNSATISFIED OR ARE NOT ADEQUATELY ADDRESSED BY CONVENTIONAL MEANS. TH ...

SILICON P-N JUNCTION PHOTODIODES (AXUV DIODES) WITH STABLE, THEORETICALLY PREDICTABLE QUANTUM EFFICIENCIES IN THE SOFT X-RAY (1 TO 100 NM) WERE DEVELOPED BY US RECENTLY LEADING TO THEIR USE FOR THE ESTABLISHMENT OF AN INDEPENDENT RESPONSIVITY SCALE FOR THE SOFT X-RAY REGION. THE LARGEST ACTIVE AREA DIODE DEVELOPED SO FAR IS 3 CM(2) LIMITING THE SOLID ANGLES DURING SURFACE ANALYSIS STUDIES. FABRICA ...

EXPERIMENTS AT THE MASSACHUSETTS INSTITUTE OF TECHNOLOGY, THE JOHNS HOPKINS UNIVERSITY, AND QUANTUM MAGNETICS HAVE SHOW THAT CORROSION REACTIONS CREATE MEASURABLE MAGNETIC FIELDS. IN CONTRAST TO OTHER TECHNIQUES, MAGNETIC DETECTION OFFERS THE POSSIBILITY OF DIRECTLY DETECTING CORROSION PROCESSES NONINVASIVELY FROM OUTSIDE THE CORRODING VESSEL. IN PHASE 1, IN COLLABORATION WITH THE MARINE CORROSION ...
