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 ...

Interference of unburned and activated carbon in fly ash with air-entraining admixtures (AEA’s) in fresh concrete mixtures is a major concern in the concrete industry. Therefore, a rapid and accurate measurement of adsorption capacity of fly ash is of great interest to this industry. In this project, a new method is suggested, which can qualitatively and quantitatively measure different surfact ...

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 ...

The project will determine the technical feasibility of developing state-of-the art information system technology for districts and schools that addresses the accountability, planning, management, and evaluation functions essential to achieving comprehensive education reform and increased productivity in education. This research and development effort aims to overcome the serious lack of informat ...

This Phase I R&D project will determine the feasability and commercial potential of a Data Services System designed to support district and school efforts to meet NCLB standards related to equity, continuous improvement, and accountability. The design incorporates: 1) a Data Use Framework representing a cohesive, innovative, and research-based approach for effectively structuring multiple uses of ...

THE DEVELOPMENT OF AN UNPRECEDENTED PUBLIC SECTOR/PRIVATE SECTOR BUSINESS PARTNERSHIP AMONG PRIVATE BUS OPERATORS, VISITOR AND CONVENTION BUREAUS (C&VB) AND PUBLIC TRANSIT AGENCIES TO MEET THE GROWING TRANSPORTATION NEEDS OF THE MEETING MARKET (E.G., CONVENTIONS AND CORPORATE MEETINGS). THIS WILL DETERMINE THE FEASIBILITY OF ESTABLISHING A FIXED-ROUTE SHUTTLE SERVICE BETWEEN HOTELS AND CONVENTION ...
