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 ...

PARAMETRIC X-RADIATION (PXR) IS PROPOSED AS AN INTENSE, TUNABLE, MONOCHROMATIC HARD-X-RAY SOURCE FOR THE DETECTION OF EXPLOSIVES. THIS RADIATION IS HIGHLY COLLIMATED, HAS A BANDWIDTH OF 0.1, AND AN INTENSITY EQUAL TO THAT OF SYNCHROTRON RADIATION ON A PER ELECTRON BASIS. PXR GENERATION IS ACHIEVED BY PLACING CRYSTALS INTO THE PATH OF ELECTRON BEAMS WITH ENERGY OF 6 MEV OR GREATER. THE VIRTUAL PHOT ...

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 ...

AN AIR-TRAFFIC FLOW MANAGEMENT (ATFM) TOOL BASED EITHER ON STRICT MATHEMATICAL FORMULATION AND OPTIMIZATION, AND/OR ONEBASED ON HEURISTIC KNOWLEDGE ABOUT DISTRIBUTING THE FLOW OVER THE NETWORK MAY PROVIDE A SOLUTION TO THE PROBLEM, PERHAPS MUCH BETTER AND OBJECTIVE THAN THE ONE MADE PRESENTLY BY A CADRE OF EXPERTS UNDER STRESSFUL CONDITIONS. THE SYSTEM SHOULD COMPLEMENT THE HUMAN DECISIONS MADE DA ...
