The goal of this research is to develop electronic design automation (EDA) tools to automate the following three major radiation-hardened-by-design (RHBD) tasks: (1) The capture of RHBD design constraints and design rules for sub-90nm mixed-signal designs in an industry-standard EDA data base, (2) Checking and verifying if a given sub-90nm mixed-signal design satisfies all the RBHD design const ...

It is well known that satellite communications and radar signals propagating in the natural ionosphere can be disturbed. It has also been widely reported that the ionosphere is subject to even greater disturbances following nuclear detonations. Hence the design of robust satellite communications and radar systems must take into account the effects of ionospheric disturbances. Radar and communic ...

Orora Design Technologies, Inc. proposes to develop an innovative computer-aided design (CAD) based methodology and enabling tools for rapid radiation-hardened prototyping and migration of military satellite microelectronics. A key innovative tool to be explored is automated generation and validation of behavioral models for complex analog, digital and mixed-signal circuits, including radiation e ...

THIS PROGRAM DEALS WITH USING THE DIGITIZED VIDEO TDR LIQUIDLEVEL DATA PREPARED UNDER CONTRACT (NRC-04-84-146) OF THE MEMT-4 TEST FROM THE LOCA SIMULATION IN NRU PROGRAM. THESE NEW DATA AND TECHNIQUES WILL BE APPLIED TO ESTIMATE THE VOIDFRACTION, LIQUID LEVEL, AND LOCAL HEAT TRANFER CONDITIONS FOR THE OTHER NRU TESTS WHERE ONLY SELF POWERED NEUTRON DETECTORS (SPND'S) AND THERMOCOUPLE DATA ARE AVAI ...

More than 6,000,000 auto accidents occur in the U.S. each year, with about one third resulting in injury and 40,000 resulting in fatality. Approximately thirteen percent of these crashes involve pedestrians. A much broader group of generalized roadway obstacles including pedestrians, other automobiles and non-fixed objects, is responsible for over ninety percent of the accidents. A reasonably p ...
