The exchange of ship ballast water has introduced non-native organisms to ports around the world. These bioinvaders are non-indigenous species that have the potential to upset local ecological systems and economics. Various treatment methods are in limited use or experimentation: heat treatment, ultraviolet, chemical, and filtration. These are successful in eliminating a portion of the organis ...

Rail inspection has seen steady, incremental advances for decades. From early Sperry ultrasonic inspection cars to EMATS, rail NDE has followed a tried and true path ¿ launch carefully selected critical angle waves to inspect a region of the rail under or near the sensors. In this proposal, we take a fundamental departure from that tradition to better differentiate critical defects. Our approac ...

A 3-DIMENSIONAL ATTITUDE SENSOR WHICH USES GPS CARRIER PHASEINTERFEROMETRY IS PROPOSED FOR ANALYSIS AND CONCEPT TESTING IN PHASE I, AND PROTOTYPING IN PHASE II. THE RESULTING SENSOR WILL BE ACCURATE AT ANY LATITUDE. ADROIT SYSTEMS PROPOSES TO ENHANCE ITS SUCCESSFUL 2-DIMENSIONAL, STATIC GPSATTITUDE DETERMINING SYSTEM (ADS) SO THAT IT WILL OPERATE UNDER DYNAMIC CONDITIONS WHILE MEASURING 3-DIMENSIO ...

AN INNOVATIVE OBSTACLE DETECTION SYSTEM BASED ON A RAIL-GUIDED PROPELLER-DRIVEN POD CONTAINING A MICROWAVE RADAR SENSOR IS PROPOSED. THE SENSOR POD WILL TRAVEL A FEW MILES AHEAD OF THE HIGH SPEED TRAIN OR MAGLEV VEHICLE, DETECT POTENTIAL OBSTACLES, AND ENACT AN APPROPRIATE WARNING OR AVOIDANCE PROCEDURE. THE PROPOSED OBSTACLE DETECTION SYSTEM HAS MANY HIGHLY DESIRABLE FEATURES INCLUDING: A VERY LO ...

THE ULTIMATE OBJECTIVE OF THIS RESEARCH EFFORT IS THE DEVELOPMENT OF A SHIP MANEUVERING SIMULATION SOFTWARE PACKAGE FOR SHIPBOARD USE IN MANEUVERING ASSESSMENT, PASSAGE PLANNING AND TRAINING. THE SOFTWARE MUST OPERATE IN A STAND ALONE MODE AND/OR INTEGRATED WITH THE SHIP'S NAVIGATION AND CONTROL SYSTEM. THE PHASE 1 EFFORT INCLUDES THE INITIAL DETERMINATION OF THE REQUIREMENTS FOR THIS SOFTWARE PAC ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

A NEED EXISTS TO MONITOR VIBRATION IN HIGHWAY BRIDGES. IT IS DESIRABLE TO MONITOR MANY POINTS ON THE BRIDGE. THE CURRENT PROBLEM IS THAT SENSORS MUST BE WIRED TO A CENTRAL LOCATION. WIRE IS DIFFICULT TO INSTALL AND TO MOVE. THE SOLUTION IS TO COLLECT SENSOR DATA BY RADIO. A SYSTEM EXISTS THAT ELIMINATES WIRE. IT GATHERS SENSOR DATA TO A CENTRAL LOCATION BY RADIO. THE SYSTEM'S UNIQUE FEATURE IS THA ...
