FY005 Accomplishments for Colony Project

Description: The Colony Project is developing operating system and runtime system technology to enable efficient general purpose environments on tens of thousands of processors. To accomplish this, we are investigating memory management techniques, fault management strategies, and parallel resource management schemes. Recent results show promising findings for scalable strategies based on processor virtualization, in-memory checkpointing, and parallel aware modifications to full featured operating systems.

Final Report, Interagency Agreement No. DE-AI03-97ER62461, Elevated CO2 and Limited Water Supply Effects on Carbon Processes and Sequestration in a C4 Grass (Sorghum) Ecosystem

Description: Free-air CO{sub 2} enrichment (FACE) experiments were conducted at ample and limited levels of soil moisture on sorghum in 1998 and 1999 at the University of Arizona, Maricopa Agricultural Center, Maricopa, AZ. Numerous measurements were taken including biomass production, grain yield, soil carbon sequestration, N{sub 2}O production, stomatal conductance, leaf water potential, canopy temperature, net radiation, and reflectance at many wavelengths. Accomplishments are listed and discussed.

Development of (Mn,Co)3O4 Protection Layers for Ferritic Stainless Steel Interconnects

Description: A spinel-based surface protection layer has been developed for alloy SOFC current collectors and bi-polar gas separators. The (Mn,Co)3O4 spinel with a nominal composition of Mn1.5Co1.5O4 demonstrates an excellent electrical conductivity and thermal expansion match to ferritic stainless steel interconnects. A slurry-coating technique provides a viable approach for fabricating protective layers of the spinel onto the steel interconnects. Thermally grown protection layers of Mn1.5Co1.5O4 have been… more

Diesel Engine Waste Heat Recovery Utilizing Electric Turbocompound Technology

Description: Caterpillar's Technology & Solutions Division conceived, designed, built and tested an electric turbocompound system for an on-highway heavy-duty truck engine. The heart of the system is a unique turbochargerr with an electric motor/generator mounted on the shaft between turbine and compressor wheels. When the power produced by the turbocharger turbine exceeds the power of the compressor, the excess power is converted to electrical power by the generator on the turbo shaft; that power is then u… more
