In the inspection and quality assurance framework, coercimetry refers to non-destructive testing of mechanical properties based on measurements of the magnetic characteristics of a metal. This technology relies on the continuous and noticeable (100-400%) increase in the magnitude of the coercivity, while the metal passes from as-delivered to its final state. As both magnetic and mechanical propert ...

Research conducted in Phase I identified a range of data sources providing vehicle related information to consumers shopping around or interested in knowing more about vehicles. Majority of the commercial data sources focused on vehicle features, new/used/CPO pricing, and vehicles listings. Such data sources lacked safety as their central focus, which is a concern for U.S. Department of Transporta ...

eTEXAS is an integrated traffic and communications simulator developed in cooperation with the US Department of Transportation (USDOT) to support the development of Connected Vehicle (CV) Apps and to perform research on vehicle and roadside Dedicated Short-Range Communication/Wireless Access in Vehicular Environments (DSRC/WAVE) communications using the Society of Automotive Engineers (SAE) standa ...

Accessing a freight locomotive is one of the most basic, daily tasks performed by a railroad engineer. However, this task has historically been difficult due to several factors such as the first step which may be 19 inches above the top of the rail, weather conditions which may make the steps slippery, and the fact that the ground surrounding the locomotive may be uneven or covered in debris or ba ...

TRANSPORTATION SYSTEM STUDIES REQUIRE IN-SERVICE INSPECTION USING NONDESTRUCTIVE EVALUATION (NDE) TECHNIQUES FOR FLAW DETECTION AND CHARACTERIZATION. IN CASES WHERE SUCH DEFECTS ARE SMALL COMPARED WITH THE THICKNESS OF THE SECTION, ULTRASONIC METHODS ARE CONSIDERED TO BE THE MOST SUITABLE. IT WOULD BE IDEAL TO MAKE SUCH MEASUREMENTS REMOTELY WITH A SYSTEM COMBINING THE STRONG FEATURES OF ULTRASONI ...

THE PURPOSE OF THIS RESEARCH IS TO STUDY THE FEASIBILITY OF QUANTIFYING THE EFFECTS OF IREASED AUTOMATION ON THE WORKLOAD AND PERFORMANCE OF THE FEDERAL AVIATION ADMINISTRA-TION'S AIR TRAFFIC CONTROLLER. IN PHASE I, RESEARCH WILL FOCUS ON ADAPTRING OUR CURRENT HUMAN PERFORMANCE MODEL TO REPRESENT THE JOB CHARACTERISTICS OR ATTRIBUTES THAT WILL DETERMINE LEVELS OF WORKLOAD AND PERFORMANCE IN THE AD ...

WE PROPOSE A RESEARCH AND DEVELOPMENT PROGRAM TO DESIGN A LASER RADAR SYSTEM FOR MEASURING ROADSIDE ENCROACHMENT. A SEQUENCE OF LASER PULSES IS USED TO DETERMINE THE VEHICLE'S VELOCITY, AN X-Y POSITION MAP, AND THE DISTANCE FROM THE MEASUREMENT SYSTEM. THE ROADSIDE ENCROACHMENT POSITION IS DETERMINED FROM THE X-Y MAP OF THE VEHICLE'S LOCATION. THISMAP ALSO INCLUDES INFORMATION ON THE VEHICLE SHAPE ...

THIS PROPOSAL DESCRIBES AN INNOVATIVE FILTERING TECHNIQUE THAT CAN BE USED TO DETECT AND REJECT OUT-OF-TOLERANCE MEASUREMENTS FROM A DIFFERENTIAL GPS NAVIGATION SOLUTION. THE TECHNIQUE CAN BE APPLIED FOR BOTH MOBILE AND STATIC APPLICATIONS AND COULD BE INTEGRATED INTO SHIPBOARD OR REFERENCE STATION GPS RECEIVERS. USING THE FILTER DESIGN PROPOSED, ERRORS CAUSED BY MULTIPATH, SATELLITE, RECEIVER ORR ...

THE RECOGNIZED LOW LEVEL WIND SHEAR PHENOMENON KNOWN AS A MICROBURST POSES A SERIOUS AIR SAFETY THREAT TO COMMERCIAL AVIATION WHILE IN A LANDING OR POSES A SERIOUS COMMERCIAL AVIATION WHILE IN A LANDING OR TAKEOFF PATTERN. THIS LOW LEVEL WIND SHEAR HAS BEEN DEMONSTRATED TO DE A THIS LOW LEVEL WIND SHEAR HAS BEEN DEMONSTRATED TO BE A MAJOR CONTRIBUTING FACTOR TO SEVERAL CRASHES OF COMMERCIAL AIRLIN ...
