However, the design process for FPGA implementation is time-consuming with multiple… more
Abstract:In order to provide the best protection to our armed forces, and to our country, we need to know where our opponents are, and what they are doing. This includes tracking their movements over long periods of time, and across large areas such that multiple sensor and seeker systems would need to be… more
Abstract:The inter-domain routing protocol BGP (Border Gateway Protocol), was designed for statically configured land-based networks which experience infrequent topology changes. BGP is remarkably successful in the stable "network-of-networks" environment it was designed for and is one of the fundamental… more

Abstract:ATC will combine the fault tolerance and scalability of an Active Replication system with a dynamic Peer-to-Peer back-end to build a Reliable Services for Continuity of Operations (ReSCO) system. The ReSCO system will provide true dynamic automated application and service mobility while providing… more
Abstract:The Air Force has identified the need for an assured routing system for the Airborne Network (AN) that will protect the routing infrastructure from security attacks designed to disrupt the operation of the network. Subversion of the network routing function by attackers could be catastrophic for… more
Abstract:Transporting multimedia information over multi-domain heterogeneous and dynamic networks has significant advantages in both the military and civilian arenas. . In order for these networks to be efficiently employed, there needs for methods that can guarantee a minimum level of Quality of Service… more
Abstract:The US Army has identified a need for a solution to correct problems that arise during the use of stateful inspection devices in asymmetrically routed networks. These stateful inspection devices, such as firewalls and intrusion detection systems, monitor communications sessions in order to provide… more
Abstract:A set of vocoder translation methods will be developed for use in voice communications applications where different vocoder algorithms are being used across the application. The translation methods will provide reduced complexity and increased performance from that of digital tandem approach. The… more
Abstract:DESCRIPTION (provided by applicant): Nucleic acid analysis is the essential foundation of many biomedical research and diagnostic methods. Among these, microarray-based gene expression profiling has become a powerful research tool for understanding basic d
isease biology, and a powerful diagnostic… more
Abstract:Responsible and efficient use of agrochemicals is a balance between mitigating the undesirable drift and other off-site movement and optimizing the efficacy of the applied spray. Often, these demands can be in direct conflict, e.g., very large droplets reduce drift but may run off the target or may… more
Abstract:Gun barrel bores have been traditionally plated with chromium to reduce erosion and increase service life. However, the chrome electro deposition process generates hazardous waste and the DoD has been moving to eliminating its use. Liners made from Tantalum ?" tungsten (Ta-W) alloys have been… more
Abstract:Detection and countermeasure of Laser Activated Devices (LADS) in today's battlefield is of great importance. Current optics detection technology can be extended to the LADS detection mission, but often suffer from several operational challenges. Arete Associates approach can provide rapid optics… more
Abstract:This project develops an innovative, enabling technology for precision attitude control of guided munitions. An imaging sensor system is used to precisely measure airframe attitude relative to the velocity vector, eliminating the time dependent heading angle inaccuracies common to all GPS/INS based… more
Abstract:Technology research and development in such areas as next-generation atomic clocks, quantum information processing with trapped ions, and atomic spectroscopy is impeded by the lack of commercially available laser sources that meet the required specifications of wavelength tuning range, output power,… more
Abstract:Arete Associates (Arete) proposes to develop advanced algorithms for landing area characterization from LADAR data for the purpose of assisting helicopter landing during brownout. Our algorithms will discriminate ground from non-ground objects; remove outlier data; identify flat… more
Abstract:Arete proposes to create the software application PERICLES (PERIscope CLassification of Ships) capable of automatically recognizing and classifying marine targets viewed in submarine imaging systems.
Abstract:One of the major technical challenges of modern military and commercial rotary wing aviation is effective instrument aided navigation in brownout or whiteout conditions that can occur during landing or maneuvering in sandy, dusty, snowy or marine environments. Helicopter prop-wash churns up dense… more
Abstract:A principal limiter of airborne MAD systems is geomagnetic noise. The long coherence length of geomagnetic noise recommends the use of correlation processing against a reference sensor outside the search area for noise mitigation, and an air-deployed buoy-mounted geomagnetic reference sensor system… more
Abstract:The problem of sniper detection and neutralization proves to be one of the more significant issues facing the troops presently deployed in Iraq and Afghanistan today. This unfortunate reality has spurred both industry and the DoD to press for immediate and effective solutions to the detection and… more
Abstract:In recent years the number, capabilities, and types of Unmanned Aerial Vehicles (UAVs) has grown dramatically, resulting in an increase in the variety and complexity of mission scenarios for these vehicles. The successful proliferation of UAV assets into missions, such as convoy protection,… more
Abstract:There is a demonstrated need for improved detection of improvised explosive devices in the modern battlefield. Thermal detection of disturbed soils associated with IED burial offers a robust signature, but the signature strength in the presence of natural clutter (including effects due to… more
Abstract:Missile systems such as Hellfire provide outstanding lethality, but use traditional gimbaled seeker heads that are too expensive and heavy to meet increasing missile loadout requirements. The reduced weight and lower cost of Strapdown Semi-Active Laser seekers enable missile loadouts that provide… more
Abstract:Predetermined, hard-wired processing architectures with static resource allocation and task distributions suffer from single points of failure, inefficient performance or failure in dynamic situations and have little to no run-time decision making ability concerning task redistribution and… 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.
