A NEW TECHNIQUE IS PROPOSED FOR THE PREPARATION OF METAL-SUPPORTED METAL (MSM) CATALYSTS. THE KEY FEATURE OF THIS TECHNIQUE INVOLVES THE PREPARATION OF A THIN LAYER OF POROUS METAL ON TOP OF A METAL SUBSTRATE SUCH THAT THE POROUS METAL SURFACE IS AN INTEGRAL PART OF THE METAL SUPPORT. SUBSEQUENT INTEGRATION OF PT AND RH ON THE POROUS METAL SURFACE WILL PRODUCE THE MSM CATALYST. THIS CATALYST IS US ...

THE EXISTING METHODOLOGY OF DESIGN AND FABRICATION OF SEMICONDUCTOR MANUFACTURING EQUIPMENT IS AN EXPENSIVE AND TIME CONSUMING PROCESS. TO KEEP PACE WITH THE RAPIDLY ADVANCING SEMICONDUCTOR INDUSTRY, IT IS NECESSARY TO DEVELOP A COMPUTER BASED ENVIRONMENT TO QUICKLY SIMULATE THE FEATURES OF THE MANUFACTURING EQUIPMENT BEFORE IT IS TURNED INTO A PHYSICAL PROTOTYPE. APART FROM ACHIEVING CONSIDERABLE ...

PRESENT TURBOJET ENGINE CONTROL SYSTEMS, WHICH ARE COMPRISED OF: CONTROLLER, FUEL METERING DEVICE, SENSORS, CONNECTORS, AND HARNESSES ARE THE SINGLE MOST EXPENSIVE SUBSYSTEM ON EXPENDABLE TURBOJET ENGINES. THE SIZE AND COST OF EXPENDABLE TURBOJET ENGINES HAS STEADILY DECREASED. HOWEVER, THE ENGINE CONTROL SYSTEM COST HAS RE MAINED RELATIVELY CONSTANT. ELECTRONIC CONCEPTS PROPOSES TO DEMONSTRATE TH ...

THE PROPOSAL RESPONDS TO PUBLIC AND US EPA PRESSURE ON THE PULP AND PAPER INDUSTRY TO REDUCE POLLUTING EMISSIONS. PULP FROM THE MANUFACTURE OF PAPER, CONTAINER BOARD, TISSUE AND BAGS IS PRIMARILY PRODUCED BY THE KRAFT PROCESS. THIS PROCESS REDUCES WOOD CHIPS TO PULP USING SODIUM SULFIDE AND SODIUM HYDROXIDE. AS A RESULT, LARGE QUANTITIES OF NOXIOUS SULFUR CONTAINING GASES MAY BE EMITTED FROM THESE ...

The predominant concern of evolving high-speed network architectures is fault tolerance. High-speed networks will expereince a variety of faults, such as link or node failures, excessive buffer overflow due to faulty flow and congestion control mechanisms, and partial failure of the switching fabric. The main goal of this research is to increase the availability of essential network services witho ...

AN ACCURATE KNOWLEDGE OF THE MAXIMUM FIBER STRESS OCCURRING DURING PAYOUT IS CRITICAL TO IMPROVE THE RELIABILITY OF CURRENT AND FUTURE DISPENSER DESIGNS FOR FIBER OPTIC GUIDED VEHICLES. THE FIBER DEFORMATIONS OCCURRING AT THE PEEL POINT ARE A DIRECT INDICATION OF THE MAXIMUM FIBER STRESSES UNDER NORMAL PAYOUT CONDITIONS. IN ADDITION, THE FIBER DEFORMATIONS AT THE PEEL POINT PROVIDE AN INVALUABLE M ...

Aerospace systems undergo environmental stressing which ultimately limit their useful life. Empirical rules and constant inspection are required for commercial and military aircraft because real-time data are not known for the high-cost systems. This effort proposes imbedded microelectronic and microelectromechanical devices to constantly monitor aerospace systems and a life-cycle analysis of the ...

THE OBJECTIVE OF THE PROPOSED PROJECT IS TO DEVELOP AND DEMONSTRATE A LOW- COST ALTERNATIVE TO A MODIFIED CLAUS PLAN FOR CONVERSION OF SO2 TO ELEMENTAL SULFUR, AND, MORE SPECIFICALLY, TO OPTIMIZE AN EXISTING ACID RAIN SORBENT REGENERATION PROCESS DEVELOPED BY SANITECH TO YIELD DIRECTLY A PURE ELEMENTAL SULFUR PRODUCT. IN SANITECH'S PRESENT REGENERATION PROCESS, APPROXIMATELY ONE- QUARTER OF THE LI ...
