The United States has a vast network of pipelines used for fuel transport. This infrastructure, installed in 1950–1970, is one of the largest in the world. Yet poor/missing records of the materials used, combined with the overall age and associated environmental degradation effects, often results in unsafe operation. Current non-destructive inspection techniques are only capable of detecting mat ...

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 ...

Automatic Direct Surveillance Broadcast (ADS-B) can be used to provide seamless integration of space and vehicles and aircraft and for more efficient airspace use as the number of commercial space vehicles operations increase. This proposed Phase II will continue the development of techniques and equipment needed to allow for commercial space vehicles to be tracked via 1090ES ADS-B for internation ...

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 ...

This SBIR Phase I proposal to FHWA requests support for Elliott Technologies, Inc. to demonstrate the feasibility of using a handheld device or a single board computer to verify a simple interface between a user and simulated Safety Warning System messages, Simulated dedicated short range communications, and simulated High accuracy nationwide differential GPS. The significance of this proposal wi ...

LABORATORY EXPERIMENTS CONDUCTED IN A STRATIFIED TOW TANK ARE PROPOSED TO CHARACTERIZE VORTEX WAKES UNDER THE INFLUENCE OF ATOMOSPHERIC DISTURBANCE. FLOW RESEARCH HAS DEVELOPED INNOVATIVE TECHNIQUES FOR STRATIFYING THE FLUID IN THE TANK, GENERATING A CURRENT SHEAR AND CREATING AMBIENTTURBULENCE WITH GOOD CONTROL. SUCH CAPABILITIES WOULD FACILITATE THE ISOLATION OF THE EFFECTS OF THE DISTURBANCE S ...

Coating disbond on buried pipelines contineus to be a major problem world-wide. Disbonds left unrepaired promote both corrosion and stress-corrosion cracking, which are much more costly to repair. Improved inspection technology is currently needed to detect and characterize disbonds. HD Laboratories, Inc. proposes to refine and test a novel method of detecting and assessing coating disbonds and ...
