Our work demonstrates the effectiveness of space-time inference on graphs, robust matrix completion and second order analysis… more
Abstract:ABSTRACT: The correct representation of a resident space object's state uncertainty and the accurate propagation of the uncertainty by way of the Fokker-Planck equation, collectively referred to as uncertainty consistency, is fundamental to space situational awareness and the problems of… more
Abstract:Numerica proposes to developed advanced algorithms for constructing a UAS vehicle model from ATC surveillance data in real-time. Using functional descriptions of aircraft performance and computationally efficient sampling techniques, UAS model parameters are estimated, and aircraft maneuvers that… more
Abstract:The U.S. DoD has made defense against regional missile threats a top priority. In response MDA is pursuing a Phased Adaptive Approach, which includes new sensors, such as Airborne Infrared (ABIR) and the Precision Tracking Space System (PTSS). Recently, regional missile defense has focused on raid… more
Abstract:All sensors are less than perfect in their perception of the environment, including knowledge of their own position and orientation. These errors lead to inaccuracies in fulfilling their responsibilities, and less than optimal performance in support of warfighters. When sensors in a network seek to… more
Abstract:ABSTRACT: Space surveillance is that component of space situational assessment and protection that makes use of multisource data to track and identify space objects. Given the increasing importance of space, the need to protect space assets, and the increasing number of objects in space, an… more
Abstract:Nutronics, Inc. proposes a solution to the problem of compensation in the Deep Turbulence regime and the related paradox that plagues the Directed Energy community: For nearly all military applications with noncooperative targets, if the turbulence is so severe that AO is needed, then the current… more
Abstract:ABSTRACT: Military-class Adaptive Optical (AO) system technology remains highly specialized and typically must be tailored to the application of interest. Nutronics, Inc. proposes to address the challenges posed by next generation military-class AO applications by developing and delivering a state… more
Abstract:Directed Energy (DE) systems offer the promise of dramatic improvements in capability for self defense and area defense systems along with an enhanced precision strike and engagement capability. Unfortunately, turbulence causes the beam to break up at the target, significantly limiting the range of… more
Abstract:Ophir's Phase I research was highly successful and all contract objectives and tasks were successfully completed. In Phase II, Ophir proposes to continue this important research by developing and flight testing a multifunction, low-cost, laser radar capable of enhancing aviation safety by… more
Abstract:This multiphase project develops higher heat resistant materials for use in face shields of self-contained breathing apparatuses (SCBAs) and brings
them to commercial markets. Key findings of the Phase I work are that polyethersulfone (PES) is a promising replacement for polycarbonate (PC)
Abstract:Nanosatellites are receiving increased interest since they are proving reliable for surveillance, communication and other space missions. Also, the possibility of launching "constellations" of them offers unique capabilities for low-cost experimentation, sensing and communications in… more
Abstract:A spacecraft thermal control system must keep the cabin (both air and its structure if manned) and electronic equipment within a narrow temperature range even though the environment may vary from very cold to warmer than room temperature. Since water is safe to use and an excellent coolant (other… more
Abstract:On-site activated decontaminants are ideal because the activated solution is highly reactive and can quickly destroy chemical and biological warfare agents, but prior to activation the decontaminant ingredients can be safely stored for years, shipped, handled and have a long shelf life. TDA"s… more
Abstract:TDA Research, Inc proposes to develop a compact, low power, high life-cycle computer controlled Programmable Force Generator (PFG) that can generate any force between 0 and 700 lbf during any phase of the exercise motion. The proposed device uses a closed loop control system to maintain the… more
Abstract:DESCRIPTION: The overall project goal is to develop sorbents that remove catalytic metals used in drug synthesis, which if not adequately removed between synthetic steps and from the final active pharmaceutical ingredients, can lead to toxic side-effects.Sorbents are being designed to meet new U.S.… more
Abstract:The respiration of fresh fruits and vegetables (FF & V) converts oxygen from the surrounding atmosphere into carbon dioxide, moisture and ethylene. While ethylene is used under controlled conditions as a ripening agent, the presence of even small amounts of ethylene gas in shipping and storage… more
Abstract:The explosive growth of biofuels in recent years has shown that there is great potential for biomass to be a raw material for the production of transportation fuels. Possibly the most economical means to produce biofuels is by the liquification of biomass (fast pyrolysis) and subsequent upgrading.… more
Abstract:The electricity produced from fossil fuels is essential to the prosperity and security of the world. On the other hand, increasing atmospheric concentrations of CO2 caused by the fossil fuel combustion is causing concern regarding global warming. Although there are several methods for separating… more
Abstract:Carbon materials have been proposed for the control rod structural materials of the next-generation nuclear power plant. Both graphite and carbon fiber carbon matrix [C/C] composites have many outstanding qualities for this application, but they are subject to rapid oxidation by air and water at… more
Abstract:Although lead-acid batteries are relatively inexpensive, they have very short life in a hybrid electric vehicle (HEV). The problem is the result of poor charge acceptance at the negative plate, and can be dramatically improved with conductive carbon additives. High surface area activated carbons… more
Abstract:Gasification technologies convert coal and biomass into synthesis gas feed streams that can either be used as a fuel for highly efficient power generation cycles or converted into value-added chemicals and transportation fuels. However, coal-derived synthesis gas contains a myriad of contaminants… more
Abstract:Although the FT process is run on a commercial scale in both South Africa and Malaysia, several challenges face the production of liquid fuels from coal, including the attrition resistance of the catalyst and downstream hydrocarbon separation. The FT process could also benefit from a highly… 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.
