Abstract:It is well-understood that actuator nonlinearities, such as free-play, can induce limit cycle oscillations (LCO) in otherwise stable closed-loop systems. In flight control systems, free-play specifications are often set conservatively in order to preclude free-play-induced LCO. However,… more
Abstract:The ability to accurately anticipate target behavior on the basis of surveillance data is critical in many military and civilian contexts. Information regarding target behavior may be drawn from a variety of sources, each of which suffers from uncertainties in the form of noise, inaccuracies, and… more
Abstract:Vehicle fuel efficiency is a complex function of many variables, including vehicle condition, vehicle loading, engine condition, terrain, fuel type, and driving style. High fuel costs increase the need to optimize fuel efficiency with respect to as many variables as possible. An affordable,… more

Abstract:Aircraft research, development, and testing programs require high-fidelity simulations and aerodynamic models. However, once flight testing begins the process of updating the simulation to match flight-test results is often ad hoc, labor intensive, and costly. Recent research has been investigating… more

The specific focus of the research effort is adaptive diagnostic and… more
Abstract:TCDL systems provide forward-deployed ground and airborne platforms with high-rate communication capabilities, supporting vital tactical data links. Currently, omni-directional TCDL antennas employed on airborne platforms maintain link closure for level flight, but struggle to maintain the link… more
Abstract:The strength of the United States military is highly dependent upon the continued superiority of intellectual resources and technology in the battle arena. Emerging trends indicate that fewer students are pursuing education in the sciences and technology. In an effort to reverse this trend,… more
Abstract:There is a need for a computing infrastructure that supports the power, weight, security, and certification requirements of the growing UAV community. To address this need, Barron Associates will develop a fault-tolerant platform, suitable for eventual certification, providing security and… more
Abstract:DESCRIPTION (provided by applicant): The proposed research involves the development of assistive technology that is based upon a force-feedback joystick. The Barron Associates Joystick Appliance (BAJA) is targeted at individuals with neuromuscular problem

Abstract:The potentially catastrophic results of entering the flutter regime mean that flutter flight testing of aircraft carries significant risk, and accurate predictions of flutter behavior are highly valuable. Recent advances have yielded aeroelastic models that are quite accurate, but these models are… more
Abstract:The Shared Reconnaissance Pod (SHARP) provides the U.S. Navy with the latest digital tactical reconnaissance capability. NAVAIR wishes to make SHARP data available to a larger number of surface terminals, thus expanding the SHARP Close Air Support mission capability. Coupled with concurrent… more
Abstract:A prototype adaptive flight control concept was developed in Phase I which better compensates for dis-turbances on the rotorcraft due to ship airwake effects and the moving ship deck during helicopter or tiltrotor shipboard operations. It is proposed to further mature the algorithms associated with… more
Abstract:DESCRIPTION (provided by applicant): The proposed research program focuses on the development of a wireless Small Animal Physiological Monitor (SAM). The SAM system will provide the capability to monitor up to 32 laboratory animals (initially rats and mice
) simultaneously, with continuous recording… more
Abstract:The overall objective of this Phase I program is to develop the architecture for a satellite data uplink system for transmitting dropsonde measurement data from the sensor to a ground-based terminal without the use of a specialized receiver or direct line-of-sight radio links from the sonde to the… more
Abstract:Recently, the Navy has seen a shift from open-ocean or "blue-water" operations to littoral or "brown-water" operations, with warships operating close to shore in high clutter environments. The TNC filter provides a low cost solution CIF improvement. This technology is applicable to several radar… more
Abstract:This Small Business Innovation Research (SBIR) Phase I Project addresses a crisis in the lack of effective glucose monitoring equipment for visually and cognitively impaired diabetics. The proposal thoroughly examines the technical and commercial feasibility of developing innovative technology that… 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.
