ALGORITHMS ARE DERIVED THAT DEFINE THE PATHS OF MAXIMUM COHERENCY FOR A SEISMIC EVENT GENERATED BY FIRING AN ARTILLERY WEAPON FROM AN ARBITRARY LOCATION. SIGNAL EXTRACTION TECHNIQUES ARE DESCRIBED TO EXTRACT THE COHERENT SIGNAL FROM AN EVENT RECORDED ON MULTIPLE RECEIVERS. SIMULATED BATTLEFIELD RECORDINGS ARE GENERATED BY TREATING THE SEISMIC SIGNATURE OF ARTILLERY WEAPONS AS IMPULSE RESPONSES FRO ...

AbTech Corporation proposes to apply its unique Statistical Network ModelingTM technology to develop a non contact prognostic assessment tool that 1) acquires, processes, and analyzes electronic radiated signal data, 2) learns the expected characteristics and patterns of specific radiated signals measured from microelectronic semiconductor devices using AbTech's statistical network modeling techno ...

INNOVATIVE ARTIFICIAL INTELLIGENCE TECHNIQUES HAVE THE POTENTIAL TO SOLVE MANY COMPLEX AIR FORCE PROBLEMS. ADVANCES IN COMPUTING SPEED AND EXISTING SOFTWARE TECHNOLOGY ALONE ARE UNLIKELY TO RESULT IN REAL-TIME AERONAUTICAL SYSTEMS CAPABLE OF MEETING THE COMPLEX REQUIREMENTS OF THE AIR FORCE MISSION. RATHER, AN ALTERNATIVE METHODOLOGY SUCH AS ABDUCTIVE TECHNOLOGY, A NEW TECHNOLOGY PRESENTED IN THIS ...

N/A

The automated inspection of gas turbine components has proven to be difficult due to their complex geometry. While ultrasonics has demomstrated excellent capabilities in detecting and characterizing the erosion and corrosion on turbine components from the hot effluent gases, it's application details laborious alignment procedures for the ultrasonic transducer during inspection. The need for automa ...

IN THIS PHASE I EFFORT, THE GOAL IS TO DETERMINE THE FEASIBILITY OF CONDUCTING ACCELERATED CORROSION TESTING OF VEHICLES BY SIMULATING 5-10-15 YEARS OF FIELD LIFE IN A COMPUTER CONTROLLED ENVIRONMENT SIMULATION CHAMBER. THE DIFFERENT REQUIREMENTS OF THE CHAMBER, THE TYPES OF ENVIRONMENTS PRESENT IN THE DIFFERENT GEOGRAPHICAL REGIONS, THE CORRELATION BETWEEN ACCELERATED CHAMBER TESTS AND FIELD COND ...

Reliability and lifetime performance data for environemntal control systems (ECS) is limited. Real-time tests require 5-15 years, and results often apply only to obsolete technology. Accelerated life testing (ALT) is a means by which reliability data may be obtained quickly and at a reasonable cost. A primary difficulty with ALT of ECS units is that typical service conditions impose multiple stres ...

N/A

There is a substantial body of evidence demonstrating that biofilms growing inside the water lines of dental units pose a significant risk as a source of infection. The problem has been recognized by practitioners, regulators, manufacturers, and the ADA, with the ADA proposing a set of guidelines for water quality that include a limit of 200 colony forming units per milliliter for the year 2000. ...
