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 ...

New engine diesel pollution is addressed in the EPA Clean Diesel Truck/Bus and low sulfur diesel rule and non-road diesel rule. Unfortunately, slow fleet turnover with extend full implementation. EPA is interested in both retrofit technologies that reduce emissions (particulate matter, volatile organic pollutants, NOx) from diesel sources and also interested in new bio-diesel implementation tech ...

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 ...

Electoronic waste (e-waste) is one of the most rapidly growing waste problems worldwide. Improper handling of e-waste results in vast amounts of toxic waste being sent to landfill and leaching into the water supply. Due to these concerns e-waste recycling is a rapidly growing industry. Unfortunately, most current e-waste recycling processes rely on either manual hand sorting or differental dens ...

This SBIR Phase I program aimes to demonstrate the feassibility of an innovative multi-polutant removal technology for the flue gas purification of small industrial boilers. Compared to the conventional flue gas purification processes, the proposed technology is more suitable for the small industrial boiler applications, and displays several advantages, such as low installation and operation cost ...
