N/A

aCADian Inc. proposes to develop a user friendly, extensible, integrated CAD environment for the design and simulation of Photonic Integrated Circuits. It will provide a high-productivity photonic layout capability, seamless integration with lightwave simulation packages. The software will be designed from the ground up to deal with the specifics of integrated optical circuits. It will incorpo ...

INNOVATIVE APPROACHES ARE DESCRIBED IN THIS PROPOSAL FOR SUPPRESSING FREQUENCY MODULATION ON A SINUSOIDAL CARRIER. PARTICULAR EMPHASIS IS DIRECTED TO THE SUPPRESSION OF IDENTIFIABLE COMPONENTS OF A COMPOSITE MODULATION PROCESS FOR THE PURPOSE OF RETAINING, FOR SEPARATE MEASUREMENT, ANY FORM OF RANGE-RATE DOPPLER SHIFT/MODULATION PRESENT. THE PROPOSED EFFORT WILL CONSIST OF AN ANALYTICAL STUDY FOR ...

Increasingly strict emissions requirements and the need to increase fuel economy and reduce service intervals have dramatically accelerated the use of monitor and control electronics in engines. traditional methods such as adjusting the air/fuel ratio to optimize catalyst performance are not effective enough to meet future requirements. Measurement of the pressure in each cylinder permits enhanc ...

N/A

SIGNIFICANT SAVINGS IN COST AND DISPLACEMENT OF VALUABLE PETROLEUM FUEL CAN BE ACHIEVED BY BURNING COAL WHEN APPROPRIATE FOR DOD POWER GENERATION REQUIREMENTS. THIS PROPOSAL OFFERS A COST EFFECTIVE, PORTABLE, COMPUTER CONTROLLED AND INTEGRATED COAL ANALYSIS SYSTEM FOR ASSESSING A COAL'S COMBUSTION PERFORMANCE. THE PROPOSED SYSTEM FOR COAL ANALYSES IS AN INTEGRATED THERMOGRAVIMETER ANALYZER (TGA), ...

This Small Business Innovation Research Phase I project will fabricate an array of gas-sensing elements from pulsed-laser deposited (PLD) metal oxide thin films on silicon wafers, which will be integrated with fiberoptics and a digital signal processor (DSP) for device operation, readout, and signal conditioning. The developed sensor instrument that can be used as a subsystem for combustion contr ...

N/A

THE WASTE HEAT EXCHANGER IS OFTEN THE LARGEST SINGLE COMPONENT IN DIESEL-EXHAUST POWERED AIR CONDITIONING SYSTEMS, AND ON ACCOUNT OF ITS HIGH MATERIAL CONTENT, IS OFTEN THE HEAVIEST AND MOST COSTLY AS WELL. THE NEED EXISTS FOR A HEAT EXCHANGER DESIGN AND FABRICATION TECHNIQUE WHICH IS COMPACT AND LIGHTWEIGHT, RESISTS FOULING FROM EXHAUST GASES, IS EASILY CLEANED, USES INEXPENSIVE MATERIALS, AND IS ...

THE RECENT DISCOVERY OF SUPERCONDUCTIVITY AT HIGH TEMPERATURE (90 DEG K) IN COPPER CONTAINING CERAMICS HAS RESULTED IN A RAPID ACCELERATION IN SUPERCONDUCTOR RESEARCH. PRODUCTION TECHNIQUES ARE BEING EXAMINED FOR THE FABRICATION OF BULK AND THIN FILM SAMPLES. THE CURRENTLY USED PROCESSES FOR MAKING THIN FILMS OF SUPERCONDUCTORS ARE PRIMARILY LIMITED TO EXPENSIVE, SMALL SCALE, LABORATORY TECHNIQUES ...
