Abstract:Composite materials comprising an active piezoelectric phase and a passive polymer phase offer significant advantages over their single phase counterparts. These include higher electromechanical performance and vastly enhanced design versatility. Several combinations of polymer/ceramic connectivity… more
Abstract:THIS PHASE I SBIR PROPOSAL WILL INVESTIGATE THE FEASIBILITY OF ADULT FOSTER CARE AS A REVENUE-GENERATING OPPORTUNITY FOR RURAL COMMUNITIES. THE PROPOSED OBJECTIVES INCLUDE: 1) DETERMINING INDIVIDUAL STATE REGULATIONS IN THE NORTHEAST REGARDING CAREGIVER TRAINING, BUILDING AND ENVIRONMENTAL… more
Abstract:APPROXIMATELY 210 BILLION DOLLARS WAS SPENT IN 1992 ON CORROSION IN THE UNITED STATES. ACCORDING TO THE NATIONAL ASSOCIATION OF CORROSION ENGINEERS, THIS IS ROUGHLY FOUR PERCENT OF THE GNP. MANY METHODS OF DETECTION HAVE BEEN DEVISED WITH SOME SUCCESS. HOWEVER, AS THE NUMBERS REVEAL, THE PROBLEM… more
Abstract:Existing balloting codes do not consider all of the forces and interactions that contribute to balloting of hypervelocity projectiles. This effort will result in the definition of a complete mathematical model and the design of an appropriate, user friendly, computational model to predict… more
Abstract:The work involves the design and testing of new enzyme-based amperometric glucose sensors. Electrical communication between the flavin redox centers of glucose oxidase and an electrode is achieved via a network of donor-acceptor relays chemically bound to a highly flexible, insoluble, high molecular… more
Abstract:The overall objective is to develop highly stable electrochemical probes for the monitoring of the reduced cofactor nicotinamide adenine dinucleotide (NADH), which is produced in many enzyme-based immunoassays. These sensors can measure NADH concentrations at low applied potentials, where… more
Abstract:This project will design and evaluate software prototypes to examine three issues in hypermedia design. 1. What is the proper balance between user and system control? 2. What strategic knowledge is needed to take advantage of the new dimensions of information available and how can the system's… more
Abstract:The development of improved implantable devices and biomaterials requires knowledge of their in vivo behavior. However, little is known about the actual loads borne by implanted devices in vivo. Direct measurement of these loads would provide extremely valuable information for the improvement of… more
Abstract:THIS PROJECT WILL PRODUCE AN OPTICAL RANGE-OF-MOTION MEASUREMENT AND BIOFEEDBACK SYSTEM THAT IS PORTABLE, PASSIVEAND CORDLESS. THIS SYSTEM WILL SPEED UP THE RECOVERY OF PATIENTS IN REHABILITATION AFTER ORTHOPEDIC SURGERY OR ILLNESS. THE SYSTEM TRANSMITS SHORT PULSES OF LIGHT THAT ARE REFLECTED BACK… more
Abstract:Inside Out vs Outside In! It seems reasonable to hypothesize that the pilot of an air vehicle will feel more in harmony with the actions of his vehicle when he is at the relative "origin" of the coordinate frame of reference of that vehicle ... and will respond more quickly and with greater accuracy… more
Abstract:THE OBJECTIVE IS TO DESIGN AND FABRICATE A PROOF-OF-CONCEPT MODEL OF A NOVEL SIX DEGREES-OF-FREEDOM TRACKING DEVICE FOR MEASURING THE POSITION AND ORIENTATION OF A HEAD OR HAND IN AN AUGMENTED REALITY ENVIRONMENT. THE FEASIBILITY MODEL TO BE BUILT IN PHASE I WILL DEMONSTRATE GREATLY REDUCED… more
Abstract:The RF transmitter/locator (TL) concept presented in this proposal enables the location and recovery of a canister such as a nose cone, artillery shell, buoy, or instrument package. The system operates over a distance of 5 mi on the surface and several hundred feet through soil, sand, or fresh water… more
Abstract:THE LONG-TERM GOAL OF THIS WORK IS TO PRODUCE AN INEXPENSIVE, ACTIVELY CONTROLLED VEHICLE SEAT SUSPENSION SYSTEM TO CONTROL LOW BACK INJURIES CAUSED BY VERTICAL VIBRATION EXPOSURE. THE SPECIFIC AIM IS TO DESIGN A LOW POWERED SYSTEM CAPABLE OF NEW OR RETROFIT INSTALLATION. THIS PHASE I PROJECT WILL… more
Abstract:THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP AND TEST TECHNIQUES WHICH COMBAT ATMOSPHERIC NOISE AND CONSEQUENTLY INCREASE THE RELIABLE RANGE OF THE DGPS/RADIOBEACON LINK. THE FOLLOWING IDEAS WILL BE EXPLORED AND TESTED: 1) WIDEBAND NOIS CLIPPING, LIMITING OR BLANKING OF NOISE IMPLUSES TO IMPROVE THE… more
Abstract:SOLID-PHASE, ENZYME-LINKED IMMUNOSORBENT ASSAYS (ELISA'S), SUCH AS THE ELISA AIDS SCREENING TEST, DEPEND ON THE DIFFUSION OF MACROMOLECULES AND ORGANIC SUBSTRATES ACROSS A QUIESCENT LIQUID BOUNDARY LAYER PRIOR TO ADSORPTION TO THE SOLID PHASE OR REACTIVITY WITH SOLID-PHASE-BOUND MACROMOLECULES.… 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.
