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 ...

Searching for street parking, a behavior known as cruising for parking, leads to excess congestion and pollution. Many recent smart parking interventions have attempted to address this issue, but the problem of effectively detecting and measuring cruising remains largely unsolved. The goal of this work is to develop methods to detect and measure cruising for parking and its effects on congestion u ...

A RESEARCH EFFORT COMPLETED RECENTLY FOR THE AIR FORCE IDENTIFIED NEW TECHNOLOGIES FOR ANGULAR MOTION MEASUREMENT. TWO CONCEPTS WERE FOUND WHICH APPEAR TO OFFER POTENTIAL FOR AN EXCELLENT COMBINATION OF SMALL SIZE, WIDE DYNAMIC RANGE, WIDE BANDWIDTH AND EASE OF FABRICATION AND UTILIZATION. ONE DEVICE, CALLED A FLUID-FILLED BENDER BEAM, USES PIEZOCERAMICELEMENTS TO PRODUCE A SIGNAL PROPORTIONAL TO ...

PRIVATE INVESTMENTS IN TRANSPORTATION CAN BE PROFITABLE. THE HORIZONTAL DEVELOPMENT PROCESS (HDP), EMPLOYING A SPECIALIZED FORM OF PEOPLE-MOVER AS A HORIZONTAL ELEVATOR (H*E), MAXIMIZES THE DEVELOPMENT POTENTIAL, REDUCES THE RISK OF HIGH COSTS OR LOW INVESTMENT RETURN. AN HDP GUIDE WITH INDEPENDENT FINANCIAL APPRAISALS INCLUDING PROFORMA DATA AND PRELIMINARY UTAG (URBAN TRANSPORTATION ACTION GRANT ...
