A high sensitivity laser-induced incandescence system is proposed for the detailed characterization of environmental soot. The Phase 1 effort has clearly demonstrated the feasibility of (1) reducing the lower detection limit of soot volume fraction and increasing the overall measurement range by at least 2 orders of magnitude from what is currently achievable, and (2) providing PM particle size me ...

Ceilings Unlimited proposes to develop a popular entertainment television show (¿The Program¿) for climate education and outreach. The Program will present tales of the human impact of climate and climate science, highlighting the role NOAA¿s climate services play in our nation¿s engagement on issues of climate and climate change. In Phase II, Ceilings Unlimited will distill the results of t ...

The Phase 2 objective is to provide NIST with a modular gauge head unit equipped with InsituTec's standing wave probe technology. The complete gauge head unit will be retrofitted to the NIST M48 which is one of the most precise measuring machines in the world. This unit will enable NIST to achieve the agency's program goal in dimensional metrology which is to provide microscale measurement capacit ...

Toyon Research Corporation proposes to develop and demonstrate a multipath mitigating antenna/receiver system for GPS geodetic applications. Our proposed system consists of a dual-channel antenna that provides spatial discrimination between the direct satellite signal and multipath signals, coupled with enhancements to the receiver architecture including multiple correlators to estimate multipath ...

THERE HAS RECENTLY BEEN HEIGHTENED CONCERN FOR THE POSSIBILITY THAT NUCLEAR POWER-PLANT ACCIDENTS DURING SHUTDOWNS COULD BE IMPORTANT CONTRIBUTORS TO THE OVERALL RISK PROFILE OF THESE PLANTS. THE 1986 SOVIET ACCIDENT AT CHERNOBYL WAS THE PRINCIPAL EVENT THAT LED TO THIS HEIGHTENED CONCERN, BUT A FEW RECENT EVENTS AT U.S. PLANTS HAVE ALSO CONTRIBUTED. TODAY, IT IS WIDELY UNDERSTOOD THAT THE RISK OF ...

SILICON PHOTODIODES WITH STABLE, THEORETICALLY PREDICTABLE QUANTUM EFFICIENCY IN THE XUV SPECTRAL RANGE HAVE BEEN RECENTLY DEVELOPED BY RAJ KORDE AND SCIENTISTS AT NIST. SCIENTISTS AT BESSY AND PTB IN GERMANY HAVE INDEPENDENTLY CONFIRMED THAT THE CALCULATED QUANTUM EFFICIENCY OF THESE XUV SILICON DIODES CAN BE USED FOR THE ESTABLISHMENT OF AN INDEPENDENT RESPONSIVITY SCALE IN THE XUV SPECTRAL RANG ...

DATA INTENSIVE APPLICATIONS PLACE A BURDEN ON EXISTING DATABASE SYSTEMS. ESPECIALLY ACUTE ARE THE REQUIREMENTS PLACED BY APPLICATIONS THAT REQUIRE DATABASE SEMANTICS BEYOND THE SCOPE OF EXISTING ENVIRONMENTS. WORK IN OBJECT-ORIENTED DATABASE TECHNIQUES PROMISES TO ALLEVIATE SOME OF THESE PROBLEMS. RECENT DEVELOPMENTS IN EXTENSIBLE DATABASE ENVIRONMENTS WILL SUPPORT THE INTEGRATION OF OBJECTAPPROAC ...
