The positioning of the control and shutdown rods is performed via the plants rod control system, which in a typical Pressurized Water… more
Abstract:As the existing fleet of US nuclear power plants pass midlife, the aging condition of safety related systems, structures, and components (SSCs) becomes increasingly important. Electrical cables, including those used for instrumentation and control, are vital for safety related systems and problems… more
Abstract:Although nuclear power plants have provided a reliable source of power for the U.S. over the last four decades, unexpected equipment failures have resulted in losses of power production and millions of dollars of revenue, which may have been avoided if the warning signs of impending failures had… more
Abstract:Unmanned Underwater Vehicles (UUVs) provide an ideal platform for conducting reconnaissance missions in riverine and coastal environments. These platforms must be able to navigate accurately without access to GPS. Analysis, Design & Diagnostics (AD & D) has teamed up with Johns Hopkins… more
Abstract:Under the Phase II program we will develop and demonstrate a wide band automated handheld sonar acoustic intercept system for divers. The Phase II system will automatically detect and classify active sonar emissions and will alert the diver when threat sonars have been detected. We will provide the… more
Abstract:Existing silicon on insulator (SOI) pixel detectors which integrate single gate transistors with substrate diodes are limited by two key problems. First, the SOI transistor performance is degraded by the large potentials that must be applied to the substrate to fully deplete the diodes. Secondly,… more
Abstract:The goal of this project is to develop an ultra low power (ULP), radiation hardened, reconfigurable analog-to-digital converter (ADC) in the 130nm Flexfet Independently Double Gated SOI CMOS process. Satellites include a large number of sensors which perform both generic system functions and… more
Abstract:ABSTRACT: The Space Plug-and-play Avionics (SPA) initiative is designed to improve the ability of the US military to respond to rapidly changing operational needs by creating, integrating, and launching a new spacecraft in less than one week. This would provide major benefits to war fighters on… more
Abstract:Research on desensitized optimal filtering techniques and a navigation and sensor fusion tool kit using advanced filtering techniques is proposed. Research focuses on reducing the sensitivity of Kalman filters with respect to model parameter uncertainties using a robust trajectory optimization… more
Abstract:DESCRIPTION (provided by applicant): Three primary sources of hematopoietic stem cells (HSCs) are routinely used in HSC therapy. These include mobilized peripheral blood, bone marrow and umbilical cord. While each source has its individual benefits, cord blood has seen increased usage over the past… more
Abstract:DESCRIPTION (provided by applicant): The three primary sources of hematopoietic stem cells (HSCs) for bone marrow transplant are: mobilized peripheral blood, bone marrow, and umbilical cord. While each source has its individual benefits and limitations, cord blood has seen increased usage over the… more
Abstract:For un-fielded propulsion systems such as the Versatile Affordable Advanced Turbine Engine (VAATE), a technical approach is needed to predict reliability and maintenance cost. This predictive ability is of value because it will enable the designers to select materials and design configurations that… more
Abstract:Decomposing monopropellant hydrazine across a spontaneous catalyst bed is the gold standard for small propulsion systems responsible for attitude control on satellites and spacecraft. Such a propulsion system is both simple and reliable, and offers reasonable performance. However, the simplicity… more
Abstract:BMDS components must function reliably when exposed to radiation, including both nuclear weapon and natural space environments. Current tools will not allow correct evaluations of system performance. Since the current radiation environment tools were not designed to handle sub-orbital trajectories,… more
Abstract:ABSTRACT: In our proposed Phase II effort, we will be demonstrating long-lived aqueous aluminum heat pipes. The work will directly demonstrate the corrosion inhibition character of two different aqueous work fluids and the long-term heat flux performance of our heat pipe designs at an operating… more
Abstract:ABSTRACT: When a solid rocket motor propellant grain contains one or more flaws (cracks, debonds, casting voids) or develops them as it ages, the risks of testing that motor is significantly increased. The responsible authority must decide between testing a motor that may destroy expensive testing… more
Abstract:In the proposed effort, ASI will be teaming with a major propulsion contractor to develop next generation thermal stabilizers for double base propellants. The scope includes chemical synthesis, propellant development and testing, and accelerated aging.
Abstract:A small, modular dropsonde launcher is being developed for Unmanned Aerial Vehicles (UAVs). Some critical measurement needs can only be satisfied by in-situ measurements. Key examples of such measurements include detailed atmospheric profiles, point meteorological conditions on the surface, and… more
Abstract:Icing is one of the most significant hazards to aircraft. There is still much research to be completed with regard to developing remote-sensing technologies for accurately identifying where icing conditions exist in clouds.

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.
