Award Data

Onboard railroad passenger information system (OPIS) is an electronic system that provides audio and/or visual information for passengers on a train. However, information received by passengers is not guaranteed since the information and service provided by the OPISs are diverse and without a common standard. Therefore, we propose a Smart Onboard Passenger Information and Entertainment, TrainAid, ...

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 seeks to demonstrate the feasibility of using impulse radar techniques to detect and identify explosive detonators. It relies on the fact that a radar impulse will excite natural electromagnetic resonances which characterize the size, shape, and material composition of an object. These resonances are present in the scattered transient return from the object and can be extracted by ...

Advance Technologies is proposing a formal software development effort to translate the State Transition Logic algorthims developed under NCHRP Project 3-66. We are proposing the use of free software such as GNAT, Linux and Umbrello to assist us in the software development. Advanced Technologies has been developing real time, safety critical, Ada83/Ada95 software for twenty years. We plan to use U ...

THERE IS A CONSTANT NEED FOR LESS COSTLY AIRCRAFT ALTITUDE SENSORS, FOR WHICH LARGE NUMBERS OF THESE SENSORS ARE REQUIRED. THE PROPOSED PROGRAM IS TO PERFORM STUDIES LEADING TO THE DEVELOPMENT OF A SURFACE ACOUSTIC WAVE (SAW) ALTITUDE SENSOR FOR AVIONICS AIR-DATA INSTRUMENTATION. THE OBJECTIVE OF THE PROPOSED PROGRAM IS TO DEVELOP A HIGH PERFORMANCE ALTITUDE SENSOR WHICH WILL UTILIZE STATE-OF-THE ...

COAL IS AN ATTRACTIVE FUEL FOR RAILROAD LOCOMOTIVES BECAUSE OF ITS DOMESTIC ABUNDANCE AND LOW COST PER UNIT OF HEAT. ONE RESTRAINT IN COAL AS A LOCOMOTIVE FUEL IS ENVIRONMENTAL POLLUTION. CONSIDERING THESE CONFLICTING CONDITIONS OF ATTRACTIVENESS AND DIFFICULTY IN USING COAL AS A FUEL, IT BECOMES QUITE IMPORTANT HOW THE COAL IS HANDLED AND CONVERTED TO HEAT FOR LOCOMOTIVE POWER. A STUDY OF HEAT EN ...

A SIX MONTH PROGRAM IS PROPOSED TO DEVELOP RIGID SYNTOCTIC POLYIMIDE FOAM PANELS POSSESSING FLAME RESISTANCE, NO-SMOKE EMISSION AND LOW THERMAL CONDUCTANCE FOR REPLACING INTERIOR MATERIALS OF TRANSPORTATION VEHICLES NOW DESIGNATED AS POTENTIALLY HAZARDOUS. AT LEAST FOUR CANDIDATE MATERIALS WILL BE PREPARED AND TESTED TO SELECT THE MOST PROMISING CANDIDATE FOR SCALE-UP IN A PHASE II PROGRAM.
