Polymer Bridge Systems, with over 8 years of research composite bridges, found that success hinges on being dollar-for-dollar cost competitive with steel and concrete. We founded the four "golden rules" that are required: the bridge must be: 1) factory build; 2) road transportable; 3) installed in 1 eight-hour day; and 4) be cost-competitive on an installed cost basis. This bridge will be buil ...

A RELATIVELY UNDOCUMENTED PROBLEM OF UNAUTHORIZED RELEASE OFSAFETY BELT AND CAR SAFETY SEAT (CSS) HARNESS BUCKLES BY YOUNG CHILDREN HAS BEEN REPORTED BY PARENTS TO THE NHTSA AND TO CSS EDUCATORS. THE OBJECTIVE OF THIS RESEARCH IS TO DOCUMENT THE NATURE AND EXTENT OF THE PROBLEM AND DEVELOP AND TEST COGNITIVE SKILL BASED SOLUTIONS TO IT. WORK WILL INCLUDE A SURVEY OF CSS USERS; VISUAL OBSERVATION O ...

Positioning and navigation have become a mainstay of everyday life in the U.S.; applications of interest include navigation of vehicles of all kinds, infrastructure mapping, and safety of life systems. Many of these recent applications have become possible through the GPS. With the recognized vulnerabilities of GPS, it is evident that equivalent backup systems must be developed. One possible so ...

The Surface Transporation and Uniform Relocation Assistance Act (STURAA) requires the use of native grasses and wildflowers within highway corridors. A major problem for the revegetation industry has been the ability to predictably establish native vegetation from seed. The production of native sods would allow for the most sensitive period of establishment-germination and initial seedling growt ...

Resodyn Corporation is proposing a material and application system that will create a low friction coating on concrete median barriers. The advanced material developed for the low friction coating is an affordable, tough, weather resistant, and environmentally friendly copolymer. The proposed application concept is for truck mounted equipment that enables a single pass application of the coating ...

Special Operations Forces (SOF) require a real time display of appr opriate data to allow the helmsman to access the damage potential to his cargo (equipment/personnel) and support his decision relative to speed and course selection when operating in rough water. Furthermore, maintenance support personnel need quantitative data to support design decisions and maintenance activities. This proposa ...

A VITAL PART OF ANY EFFORT TO IMPROVE THE EFFECTIVENESS OF CATASTROPHIC OIL AND CHEMICAL SPILL RESPONSE IS IMPROVING RESPONSE PERSONNEL TRAINING. SEVERAL ISSUES THAT ARE UNIQUETO SPILL RESPONSE TRAINING LIMIT THE EFFECTIVENESS OF A CLASSROOM APPROACH TO MEET NATIONAL CONTINGENCY PLAN TRAINING REQUIREMENTS, INCLUDING THE RAPID PACE OF TECHNOLOGICAL INNOVATION IN SPILL RESPONSE, THE NUMBER AND GEOGR ...

PRESENT TRAIN DETECTION SCHEMES RELY LARGELY ON A LOW RESISTANCE THROUGH THE TRAIN'S WHEELS TO PERTURBATE A STABLE ELECTRICAL CIRCUIT. WHILE ELEGANT IN PRINCIPLE, THE DESIGN IS PLAGUED BY OXIDE FILMS AND MATERIAL BUILDUP ON THE RAIL, SNEAK PATHS THROUGH THE BALLAST AND OTHER UNCONTROLLABLE VARIABLES. KVH INDUSTRIES PROPOSES TO DESIGN AND DELIVER A "SMART MAGNETOMETER"-BASED SENSOR PACKAGE WHICH WI ...
