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 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 ...

Electrical circuit designers at Tier 2-4 suppliers to the Department of Defense (DoD) are currently using desktop computing to design their products. To improve the circuit design in the DoD supply chain, designers will need to be able to analyze their circuits with High Performance Computing resources. Designers seeking to innovate their circuits must have access to HPC facilities that maintain c ...

The demand for renewable energy is motivating R&D efforts toward the development of novel photovoltaic (PV) technology. Efficient and low cost solar cells will have an important role in defense applications particularly powering portable electronic devices. Current solar cells based on single crystal silicon are still not at a level to be cost effective when compared to other forms of electrical g ...

Chlorine gas was first used as a weapon during World War I, and reemerged as a threat in Iraq compounding the dangers from existing improvised explosive devices. One of the significant challenges with preventing attacks that involve toxic industrial chemicals (TICs) like chlorine and ammonia is that they have genuine civilian uses for water treatment, in refrigeration systems, and other applicatio ...

A significant amount of personal injury and property damage as well as lost productivity could be avoided by speeding up the body’s adjustment cycle to new circadian schedules or re-synchronizing body schedules that have slipped or advanced. For the military, this problem is especially acute because the warfighters’ duties include dangerous equipment and a need for 24-hour operational readine ...
