Abstract:The ability to store and analyze a continuous sequence of high resolution images of a ballistic event has tremendous benefits in determining the ballistic limits for laminated carbon fiber materials. When the ability to store these images in a 3-D format is introduced, the volume of data that can… more

Abstract:Turboshaft engines are subject to various transient modes, necessitating a compressor with very high surge margin. Therefore, many devices were proposed in the past, and some of them including a recent one with a vaneless cavity by Allied Signal Engines, demonstrated impressive surge margin… more
Abstract:The ability to reduce total coolant flows to meet increased cooling and life requirements in gas turbines is crucial to improving future aircraft propulsion capability. Existing compressor core cooling (CCC) techniques concentrate on rotor and casing thermal deflection matching during… more
Abstract:The ultimate Virtual Environment system must free the user of const raining hardwire connections to the host computer or telepresence sensors. In addition to wirelessness, the headset must be unobtrusive and deliver a high quality image. We propose a research methodology and development… more
Abstract:The Stable Master Oscillator (STAMO) which is insensitive to shock and vibration utilizes a unique optical resonator. The resonator cavity is not affected by the jitter of the associated electronics or temperature variations. The concept utilizes off-the-shelf, high reliability components readily… more
Abstract:Delays in language acquisition are the most prevalent developmental problem in preschool children.acquisition of verbs poses a special challenge for children with language problems; perhaps this isendowed with syntactic and semantic information and play a central role in the development of grammaWe… more
Abstract:The ability to store digital, high resolution images at high speeds (10 kHz and higher) has tremendous commercial applications. To meet this need North Dancer Labs proposes to develop a unique high-speed Erasable Holographic Optical Storage system (E-HOS) capable of recording ~100 or more 2-D… more
Abstract:Phase I of this SBIR proposal will study the feasibility of ECHO housing accompanied with Home Health Care insurance, as a revenue-generating opportunity for rural communities. The proposed objectives are summarized as follows: 1. To perform three needs assessments in the state of Vermont of… more
Abstract:The goals of the Phase I research period are to construct and test new amperometric biosensors for the determination of several serum enzymes, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyltransferase (GGT), which are frequently associated with alcohol-related… more
Abstract:The objective of this proposal is to develop a lithium ion-selective electrode, primarily for application to the clinical determination of lithium in patients undergoing therapy for manic depression. The lithium electrodes currently available are not sufficiently selective for lithium relative to… more
Abstract:The cost and limited lifespan of strain gages for stress and vibration surveys has driven researchers to find alternate means of investigating airfoil stress and vibration. Systems based on optical sensors have been reported in the literature since the mid 1960's. These systems have been limited… more
Abstract:Clinically significant delays in language acquisition are the most prevalent developmental problemchildren. Early intervention is crucial since children with language delays are at greatly increaseddisabilities and behavioral disorders, but intervention resources are scarce and insufficient to… 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.
