We propose to develop an advanced navigation solution for public transportation passengers that will guide them from their origin to single or multiple destination points and across multiple modes of transportation. Passengers will simply need to enter their destination (and optionally a starting point) and the system will select optimal and alternative routes. The navigation software will run on ...

Datacenters house server farms that perform many different jobs ranging from search engines to supercomputing. In aggregate these computer systems already consume enormous power, and their energy requirements are increasing both in absolute terms and in proportion to the total capacity of the United States electrical grid. With higher power consumption has come greater difficulty in keeping these ...

The United States and several other countries are investing in new neutron scattering facilities as well as upgrading existing ones due to their promise for fundamental and applied research that can catalyze advances in energy, telecommunications, manufacturing, plastics, transportation, biotechnology, and health. The performance of one new type of instrument, the wide-angle polarized neutron spec ...

"SSSC is pleased to propose the development and delivery of a Hostile Fire Indication Sensor (HFIS) based on the Phase I design concept. The resulting system will limit the number of circuit card assemblies to two: one for the short wave infrared (SWIR)

Wind blades are a significant part of the installation and operating costs of wind turbines used for electricity generation. In the manufacture of wind blades, several composite elements must be joined; the joints between these elements present one of the most difficult aspects of their construction. Current practices are hand-labor intensive and result in thick bond lines. In turn, these pract ...

A heat exchanger must balance an ability to transfer heat to a fluid with the amount of power required to move the fluid through the heat exchanger. For most systems, heat transfer is largely driven by the material¿s thermal conductivity and the structure¿s surface-area-to-volume ratio. Increasing the latter factor increases the heat exchanger¿s capacity or reduces the exchanger¿s size. A ...

High current electron sources are required in numerous applications of interest to the DOE; however, current RF guns based upon thermionic cathodes and photocathodes have serious limitations. While thermionic cathodes have high average electron currents, they suffer from degraded beam quality when used in RF guns; this degradation in beam quality is due to the fact that the electron emission cann ...

The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL) produces neutrons for neutron scattering studies that allow researchers to study key materials properties. These neutrons are produced by the interaction of a very short (1 µsec), highly intense (1 MW at 60 Hz) pulse of protons within a flowing bath of mercury, in a process that deposits a large amount of thermal energ ...

RECENTLY CONCEIVED RADIATION TRANSPORT ANALYSIS TECHNIQUES WILL BE STUDIED TO ASSESS THEIR USE IN SPACE NUCLEAR POWER SHIELD DESIGN OPTIMIZATION. THE ULTIMATE AIM IS TO DETERMINE OPTIMAL COMPOSITIONS AND CONFIGURATIONS OF SHIELD COMPONENTS FOR THE PRO- TECTION OF SPACE SYSTEMS AGAINST MIXED RADIATION FIELDS FROM INTERNAL AND EXTERNAL SOURCES. PARTICULAR ATTENTION WILL BE PAID TO USING COMPOSITE AN ...

A PROBLEM EXISTS IN DRYING HEAT-SENSITIVE DRUGS DURING THEIR BULK CHEMICAL PRODUCTION. THE PRESENTLY AVAILABLE EQUIPMENT IS BASED ON CONDUCTION AS THE PRIMARY HEAT- TRANSFER METHOD; HOWEVER, IN DRYING HEAT-SENSITIVE CHEMICALS, THE JACKET TEMPERATURE OF CURRENT PROCESS EQUIPMENT MUST BE REDUCED TO AVOID THERMAL DEGRADATION OF THE DRUG. THE REDUCTION OF CONDUCTIVE DRIVING FORCE RESULTS IN DECREASED ...
