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 ...

Aging and obsolescence issues have recently led to problems with the rod control systems of existing pressurized water reactors. These issues, along with plans for plant life extension, have prompted the industry to actively seek viable options to monitor the health of these systems in order to ensure reliable plant operation for decades to come. This proposed work offers a comprehensive research ...

Current designs of Light Water Reactors (LWR) are equipped with control and shutdown rods that are inserted and withdrawn from the reactor core for reactivity control. In particular, the Control Element Drive Mechanism (CEDM) system is widely used for regulating plant power levels and core power distribution in the existing and next generation of Pressurized Water Reactors (PWRs). This system incl ...

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 variation between peak and off-peak electricity demand fluctuates up to 70 percent over the course of a 24 hour cycle. This degree of variability is a driver for costly inefficiencies within the power gridto prevent blackouts and meet customer demandas well as power sell offs to consume excess generation available during off-peak hours. Projections estimate the power demand to double by 2050 r ...

Large area neutron detectors with high efficiency, high resolution, high count-rate capability, and fast timing capabilities are required to meet the specific neutron diffraction and imaging needs of the Spallation Neutron Source (SNS) at the Oak Ridge National Laboratory. Due to the current shortage of helium-3, recently developed and existing commercial gas detectors using helium-3 as a neutron ...

DOE Nuclear Physics low-background rare-particle detection arrays require germanium detectors having the minimum possible background and maximum sensitivity. Larger p-type point-contact germanium detectors having better performance are being experimentally developed through collaboration with DOE low-background researchers. Semiconductor-detector fabrication improvements and electronic-discrimina ...

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)

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 ...
