Grinding is used to satisfy figure and finish requirements for optics, removing successive layers of material to ensure alleviation of any damage created from the prior operation. Consequently, fabrication times are slow and expensive. The optics manufacturing industry currently lacks physics-based models needed to understand the impact of process and material variables on final part quality and ...

Silicon carbide (SiC) is the ideal semiconductor for fabrication of solid state devices for power conditioning for the all-electric airplane, turbine engine actuators, and space-based power systems. These applications require switches and amplifiers capable of large currents with relatively low voltage drops. The potential for improved performance is indicated by SiC's material characteristics. Fo ...

We propose to implement a novel countermeasure against the exploitation of integrated circuit hardware. The proposed countermeasure is applicable to both FPGAs and ASICs, increases design obfuscation and promises to block embedded hardware exploits. It also is fully compatible with virtually any other hardware exploit countermeasure and reduces forensic costs when exploits are suspected. The propo ...

Ross-Hime Designs, Inc. Minneapolis, Minnesota and BAE Systems Wayne, New Jersey are pleased to respond to the DOD''s request for development of a robust, high performance Comunications-On-the-Move (COTM) system. The Ross-Hime Designs/ BAE team will deliver an operable, servo controlled pedestal with control electronics, user controllable from a Host computer. They will be developing and charact ...

The proposed effort in Phase II is to develop, produce, and demonstrate a prototype inspection platform and complementary damage modeling tool as a complete nondestructive evaluation solution referred to as the X-Ray Corrosion Detection System (XCDS). This system will be based on the state of the art radiographic techniques including narrow-bandwidth, spectral, and phase-contrast radiography, as w ...

The compound 2,3,7,8-tetrachlorodibenzodioxin (2,3,7,8-TCDD) has been called the most toxic compound known to man. 2,3,7,8-TCDD is globally distributed but is found in high concentration at many hazardous waste sites associated with the production and use of chlorinated pesticides/herbicides. Traditionally, contaminated soils have been excavated and transported off site to a hazardous waste incine ...

While the United States is increasingly reliant on space-based technologies, our satellite assets are increasingly vulnerable to attacks and collisions with debris or other satellites. Current space surveillance systems are stovepiped and unresponsive; when possible collisions ("orbital conjunctions") are detected in advance, additional tracking data can only be acquired through complex human inte ...

The state of wiring in aging aircraft has been an increasing concern in recent years. Wire deteriorates with age and environmental conditions, particularly inflight vibration, which causes wires chafing. Wire failures can result in aircraft downtime, higher maintenance costs, mission failure, and even an aircraft crash. Composite materials may present a unique solution to the aging wire problem. ...

A great deal of research has been done on thin film Carbon Nanotube Transistors. Single Walled Carbon Nanotubes (SWNTs) have exceptional electrical properties, High speed circuits require high carrier mobility, and individual SWNTs have a carrier mobility of up to 120,000 cm2/Vs and can be doped n and p-type. Enriched semiconducting SWNTs (s-SWNTs), narrowed down to individual chiralities provid ...
