Award Data

Water expansion during freeze-thaw cycles can cause deterioration in concrete, leading to scaling, cracking, and crumbling over a period of years. Resistance to this damage is achieved with a system of voids formed by adding surfactants to the fresh concrete to stabilize air bubbles naturally entrained during mixing. The volume fraction, size, and spacing of these voids are critical. It is importa ...

Broken rails are a common cause of mainline derailments and a particular concern given the increasing use of our rail system for passenger traffic and petroleum products. The progressive nature of the defects provides an opportunity for early detection of cracks before they become significant enough to cause a derailment. Unfortunately, current inspection technology does not allow these inspection ...

Use of motorcycles helmets significantly reduces the risk of fatality or serious brain injury to riders in the event of a crash, but riders often do not wear helmets in warm weather because of thermal discomfort. We propose to develop an innovative ventilation and cooling system that will maintain a cool, dry environment inside the helmet while also meeting applicable safety standards. The key the ...

This proposal presents a Phase I SBIR project to develop a high precision, low disperse rate powder disseminator for the US Army. In the development of the sensitive detecting agent, we need to release a precise amount of C&B agents in the controlled detection experiments. However, such a technology does not exist at the present time. After examining existing technologies, we believe that the r ...

Development and production of semi-permeable and permselective polymer membranes can fill a critical need for standard reference materials for AVLAG, CBART, and IPE acquisition programs. Optimizing the permselectivity of tri-block copolymers to specific chemical agents, non-traditional agents, and toxic industrial chemicals and materials will result in the formation of suitable and affordable ref ...

We propose to determine what outputs from the SSAJ measurement system would be suitable for traffic control applications, to determine what the "real time" needs and accuracies are for measurements of signature, speed, acceleration, and jerk (SSAJ), to integrate the output of our IST-222 Standard Signature Output Card with and Advanced Transportation Contorller (ATC) and finally to demonstrate pro ...

The current methodology for testing the penetration resistance of textile materials to various chemical agents has a number of drawbacks, including significant uncertainties in the resulting data, inefficiency and expense, risk to test personnel, and limited range of test conditions. The objective of the proposed work is to apply unique computer models for textiles with accompanying experimental ...

The ability to develop new technology on the basis of existing commercial technology can offer significant cost savings when compared to research programs to develop new technology from scratch. Continuing developments in mass spectrometry (MS), vacuum Systems and high speed gas chromatography (GC) sampling and analysis methods, have created an opportunity to fully demonstrate a powerful handporta ...

THIS PROPOSAL DESCRIBES A SIX-MONTH PROGRAM FOR THE INVESTIGATION INTO THE TECHNICAL FEASIBILITY OF A DEPLOYABLE, DOOR-MOUNTED PAD FOR ENHANCING THE PROTECTION LEVEL AFFORDED FRONT SEAT OCCUPANTS BY VEHICLES STRUCK IN THE SIDE DOOR AREA. THE CONCEPT PROPOSED FOR INVESTIGATION IS AN INFLATABLE STRUCTURE INTEGRATED INTO A PRODUCTION-CONFIGURED SMALL CAR DOOR. UPON IMPACT OF THE DOOR A STORED GAS OR ...
