This approach offers unmatched sensitivity and specificity for detection of all types of chemical vapors. The… more
Abstract:DESCRIPTION (provided by applicant): The sequencing of genomes has generated a huge amount of data still to be annotated. Computational methods are available to detect putative transcriptional promoter regions, but they are not 100% efficient and must be confirmed by experimentation. Unfortunately… more
Abstract:Computational fluid dynamics (CFD) is used as an analysis tool to help the designer gain greater understanding of the fluid flow phenomena involved in the components being designed. The next step in the design process is to modify the design to improve the components performance, typically performed… more
Abstract:We investigate the development of a secure fuselet runtime environment built on a foundation of aspect-oriented web services. Aspect-oriented techniques enable the modularization of crosscutting concerns such as remote access, security, and monitoring using code instrumentation. We compose… more
Abstract:This Small Business Innovation Research (SBIR) Phase II research project will develop a prototype Induced Positron Manufacturing Damage System (IPMDS) to be used to assess initial component quality, and manufacturing damage effects for Ti-6Al-4V and IN738 components. The IPMDS is based on the… more
Abstract:It has been well established that disease in stored potatoes and many other vegetables and fruits generate a variety of volatile compounds that are released into the storage space Furthermore, specific types of disease produce volatile compounds that generate unique fingerprints on ultra-sensitive… more
Abstract:Bearing failure in satellite applications is related to lubricant starvation rather than fatigue, and health monitoring systems for these applications must be able to observe subtle changes related to lubrication state. Phase I included an experimental study to identify candidate monitoring… more
Abstract:Hanger bearing failures occur unexpectedly and have resulted in loss of aircraft and life in both military and civilian rotorcraft. New Health and Usage Monitoring Systems (HUMS) that are currently being demonstrated on the UH-60 include sensing capabilities that offer the potential to diagnose and… more
Abstract:During Phase I, the Blackhawk hanger bearing and oil cooler fan bearing applications were studied in detail, including analysis of vibration and temperature data from used oil cooler bench tests (conducted by Sikorsky) and used hanger bearing bench tests (conducted by Sentient). This data, along… more
Abstract:Development of accurate and effective new diagnostic and prognostic capabilities for JSF PHM will require extensive data on both health and faulted systems states. While healthy signatures can be collected quickly and easily, faulted systems are only observed rarely, and duplicating faulted… more
Abstract:Modern turbine engine lifing approaches compute damage accumulation in real time based on actual usage, substantially increasing the useable life over a-priori cycle or hour limits based on assumed worst-case operating conditions. However, these new algorithms are complex, consume substantial… more
Abstract:The latent degradation of precision control system actuators affects dynamic performance and can push the performance characteristics of the actuator out of the regime needed for stable operation of the aircraft control system. Current system-level methods are not sensitive enough to actuator… more
Abstract:Fault detection and isolation algorithms are often developed with data from steady-state tests, and many algorithms perform well under these controlled conditions. However, when diagnostics are used in highly dynamic environments, sensitivities to changing loads or speeds become apparent. Vibration… more
Abstract:Grease lubricated bearings are widely used in aircraft for driveshaft support, fans, and accessories. These components are a maintenance intensive item requiring regular replenishment or replacement. In addition, occasional failures occur and have resulted in loss of aircraft. Sentient Corporation,… more
Abstract:Current animal telemetry devices are large and heavy due to their reliance on batteris to power the electronics and radios. Because of this, many species can't be effectively studied since they can not support the device weight. The smaller size will allow animal telemetry devices to be developed… more
Abstract:This SBIR Phase I project will develop a health and motion monitoring sensor and analysis system to support the return of military personnel with prosthetic devices to active duty. DoD is allowing increasing numbers of Soldiers with prosthetics to return to active duty if they are performance… more
Abstract:This Phase 2 project will develop and demonstrate two Small Crawler Tractor (SCT2) prototypes for wildland fire suppression and management activities. Phase 1 successfully demonstrated the feasibility of using the Phase 1 unit (SCT1) for these applications. The SCT2 will have more power, weight,… more
Abstract:Bonner and Boundary Counties, Idaho, are rural areas in transition. The people in these areas currently rely on increasingly fewer timber and forestry jobs as well as low-paying, seasonal tourist industry positions. The purpose of this project is to foster critically needed economic development in a… more
Abstract:The issue of firefighter safety and training is a significant national problem. There is a clear need for effective training methods/materials to augment existing wildfire training. Currently there is a lack of effective Internet training materials for wildland firefighters. Agency training focus is… more
Abstract:Environmental Abrasives, LLC (EA) proposes to improve the environment by recycling ceramic industrial waste and using the resulting product to reduce the impact of corroded and worn-out parts, equipment, pipelines, and structures. EA will develop, characterize, and test an innovative comminuted… more
Abstract:Human activities have allowed uncharacteristically dense forests of small diameter trees to develop. Fires, which are now suppressed, historically thinned these forests, reducing stand densities by removing weak and suppressed trees. Also, because the species harvested (ponderosa pine western larch,… more
Abstract:Diseased potato tubers in storage produce volatile organic chemicals that can be used as an indicator of the type and quantity of disease in the storage facility. By measuring the concentration of such volatile molecules, disease formation can be detected at an early stage, thereby providing an… more
Abstract:Development of an Optimal Bioaerosol Sampler with enhanced optical triggering capability is proposed, following a highly successful Phase I effort that clearly demonstrated feasibility. The threat of a bioaerosol attack can be partially mitigated by deployment of a cost-effective sensor network.… 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.
