Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 98-1
Budget: 01/01/98 - 12/31/98
PI: Unavailable

Phase 2 SBIR

Agency: National Science Foundation
Topic: 1995
Budget: 01/01/95 - 12/31/95

THE USE OF EDDY CURRENTS TO DETECT SURFACE-BREAKING DEFECTS IS WELL ESTABLISHED, AND MUCH KNOWLEDGE HAS BEEN BUILT UP IN ANALYZING THESE SIGNALS. HOWEVER, THE THEORETICAL BASIS FOR THIS TECHNIQUE IS UNDER-UTILIZED OR IGNORED. THE ELECTROMAGNETIC EQUATIONS TO BE SOLVED ARE COMPLEX, AS REALISTIC DETAILS ARE ADDED, SO THAT REAL-LIFE SITUATION IS MA...

Phase 1 SBIR

Agency: National Science Foundation
Topic: 1994
Budget: 01/01/94 - 12/31/94

THE ABILITY TO SOLVE INVERSE PROBLEMS LIES AT THE HEART OF ELECTROMAGNETIC NONDESTRUCTIVE EVALUATION (NDE). THESE PROBLEMS ARE DIFFICULT TO SOLVE FOR TWO REASONS: THEY ARE MATHEMATICALLY ILLCONDITIONED, AND THEY ARE NONLINEAR, WHICH MEANS THAT THEY INVOLVE CONSIDERABLE COMPUTATIONAL EFFORT, OFTEN REQUIRING SUPERCOMPUTER CAPABILITIES. RESEARCHE...

Phase 1 SBIR

Agency: National Science Foundation
Topic: 1993
Budget: 01/01/93 - 12/31/93

Phase 2 SBIR

Agency: National Science Foundation
Topic: 1990
Budget: 01/01/90 - 12/31/90

PREVIOUS RESEARCH HAS SHOWN THAT RECURSION EQUATIONS PROVIDE AN EXCELLENT COMPUTER HARDWARE DESCRIPTION LANGUAGE (CHDL). CURRENTLY THIS APPROACH IS NOT PRACTICAL BECAUSE IT PRODUCES SIMULATORS THAT ARE TOO SLOW. WE PLAN TO DEVELOP A METHOD FOR COMPILING ITERATIVE RECURSION EQUATIONS INTO AN EFFICIENT SIMULATOR PROGRAM IN THE C LANGUAGE, WHICH WI...

Phase 1 SBIR

Agency: National Science Foundation
Topic: 1990
Budget: 01/01/90 - 12/31/90

COMPUTATIONALLY EFFICIENT INVERSION ALGORITHMS ARE NEEDED IN A VARIETY OF DISCIPLINES, SUCH AS MEDICAL IMAGING, NONDESTRUCTIVE EVALUATION, GEOPHYSICAL PROSPECTING, AND ROBOTIC VISION. THE RIGOROUS MATHEMATICAL MODELS OF INVERSION THAT ARE ASSOCIATED WITH THESE PROBLEM AREAS ARE USUALLY NONLINEAR, BECAUSE THEY INVOLVE THE PRODUCT OF AN UNKNOWN MA...

Phase 1 SBIR

Agency: National Science Foundation
Topic: 1988
Budget: 01/01/88 - 12/31/88

Phase 2 SBIR

Agency: Department of Energy
Topic: 1984
Budget: 01/01/84 - 12/31/84

THE PROPOSED RESEARCH PROBLEM IS TO DEVELOP A SENSOR, TOGETHER WITH A MATHEMATICAL ALGORITHM, THAT WILL ALLOW THE THREE-DIMENSIONAL QUANTITATIVE EDDY-CURRENT NONDESTRUCTIVE EVALUATION OF MATERIALS AND STRUCTURES. THE APPROACH THAT WE PROPOSE IS BASED ON, AND EXTENDS, WORK ON TWO-DIMENSIONAL EDDY-CURRENT NDE THAT HAS ALREADY BEEN PERFORMED BY ANA...
