Abstract:Obsolescence, aging, reliability, and performance issues are driving nuclear facilities to replace conventional analog I & amp;C systems with digital technologies. The increased complexity of digital systems, compared to their analog counterparts, has resulted in faults that are often more… more
Abstract:No method currently exists for detecting intermittent faults in nuclear power plant cable circuits, which include circuit components, connectors, and end devices. Conventional techniques can locate hard faults, such as open or short circuits, but not the intermittent faults that occur … more
Abstract:In the U.S., almost all the 104 operating commercial nuclear power plants have applied or plan to apply for license renewal, many of which have recently received approval. This has given rise to questions about the aging of structures, systems, and components (SSCs) that are important to plant… more
Abstract:Small Modular Reactors (SMRs) are one of the most compelling options for meeting the growing clean energy demands of the U.S. While safer and costing less to build and operate than their conventional counterparts, the unique requirements of SMRs pose significant challenges to the maintenance of… more
Abstract:A light water reactor is equipped with control and shutdown rods which are inserted into and withdrawn from the reactor core to control reactivity.

Abstract:Our system concept is based on a number of ultra-low power"remote nodes"that contain: (1) a battery section; (2) a sensor section (3) and electronics section. The remote nodes will automatically detect and classify high value targets to type using AD & D"s proven automated… more
Abstract:Reliable, readily-manufacturable technologies are needed to create the next generation of high-density, high-functionality 3D integrated circuits (ICs) for integrating silicon pixel detectors with CMOS read-out ICs. Current methods for 3D IC development are severely limited by the thickness of the… more
Abstract:Today"s Navy continues to see increased demand for more power both on and off the ship. This need is largely driven by the continued development of high power density advanced weapons systems and sensors. Continued space and weight limitations for these ship applications will drive the need for… more
Abstract:ASI is pleased to team with ATK to present a novel concept for enabling large nozzle area ratio increases for future solid divert and attitude control system (SDACS) valves/thrusters. The proposed effort will demonstrate feasibility of this advanced concept through a thorough design study that… more
Abstract:The goal of the proposed effort is to demonstrate feasibility of using selective laser melting (SLM, an emerging manufacturing technique) to manufacture a subscale combustion chamber liner that features an advanced regenerative cooling technique that combines high performance with low pressure drop.… more
Abstract:A small Mars (or other celestial body) ascent vehicle is unlikely to achieve the necessary propellant fraction required to achieve orbit. Scaling down of liquid propulsion systems, as shown in the figure, is difficult. In the 100-kg class of vehicles, liquid propellant vehicle designers should… more
Abstract:Atmospheric refractive index fluctuations directly impact the propagation of laser beams through the atmosphere. A key parameter of interest to be directly acquired or derived from atmospheric measurements is the refractive index structure parameter CN2. Atmospheric refractive index, and therefore… more
Abstract:Icing is a significant aviation hazard, and icing conditions continue to be difficult to precisely forecast or locate in real time. An in-situ sensor, which can be flown coupled with a radiosonde, is needed which can both measure supercooled liquid water content in clouds as well as characterize… more
Abstract:Infrared spectroscopy is the most widely used technique for chemical characterization with a worldwide market of over $1B annually. Conventional infrared spectroscopy suffers, however, from fundamental spatial resolution limits that prohibit its application at the nanoscale. This has prevented… more
Abstract:ABSTRACT: The proposed solution would provide the United States Air Force (USAF) a thin client application for proactively identifying problem parts. Our solution is dependant on a digital Bill of Materials (BOM) which we also provide a tool for importing and loading the cleansed parts structure… more
Abstract:This proposal is directed toward Focus Area 1: Low noise high sensitivity and high bandwidth detector arrays at 1µm. Amplification Technologies Inc. has invented and demonstrated a fundamentally new technology to design and fabricate high-sensitivity photodetectors. We invented an amplification… more
Abstract:This proposed research is to investigate and validate Software Defined Radio (SDR) based, multi-function portable network sensing and intrusion detection algorithms suitable for small dismounted radio platforms used to support Command and Control (C2) standard sensor interfaces carried in the field… more
Abstract:We propose to develop and implement a set of algorithms within a unified target characterization and correlation framework capable of operating in a multiple heterogeneous sensor environment where detection, classification, localization and track priority information is exchanged among multiple… more
Abstract:Simulation tools that exist today for prediction of cosite interference in complex RF environments are able to accurately model complex platforms but they are quickly constrained by computational limits on traditional workstations. The focus of this research will be on updating existing… more
Abstract:The primary objective of this SBIR effort is to design, develop, and validate a Portable Automated Sensor Suite (PASS) Motion-induced User Symptomology Toolkit for Evaluating Readiness (MUSTER) to enable unobtrusive, real-time capture, synchronization, and analysis of environmental, physiological,… more
Abstract:This SBIR seeks to design, develop, and validate a Communication and Operational Multi-Modal Automated Navigation Device (COMMAND) that 1) combines AnthroTronix, Inc. (ATinc)'s existing Haptic Automated Communication System (HACS) and Engineering Acoustic Inc's tactors with the Lockheed… more
Abstract:The compact, versatile laser system that we designed in our Phase I effort will facilitate research into rubidium Bose Einstein Condensates (BECs), with applications including BEC fundamental science experiments, sensors and atomic clocks. Operational features readily accommodate cooling cycles for… more
Abstract:We propose to construct a prototype to demonstrate a novel optical trap design for ultracold atom experiments that will be reconfigurable between a focused-beam trap, a stationary optical lattice, and/or a moving optical lattice at high bandwidth and with no moving parts. Our prototype will also… more
Abstract:An emerging consensus in engineering holds that aleatory uncertainty should be propagated by traditional methods of probability theory but that epistemic uncertainty may require methods that do not confuse incertitude with variability by requiring every possibility be associated with a probability… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
