Pathfinder Normalized Difference Vegetation Index (NDVI) derived from Channel 1 (Red) and Channel 2 (near-infrared) of Advanced Very High Resolution Radiometer (AVHRR) onboard NOAA 14 became abnormally high for the 10-day composite from February 11 to 20 in 1999 for Western Australia. There was a solar eclipse in the satellite path on February 16 about the same time when NOAA 14 was above the e...

The University of Texas at Austin Center for · Electromechanics (UT-CEM) is a research center which specializes in pulse power technology. DoD's mission for high performance power sources has lead UT-CEM to incorporate advanced composite materials into compulsator designs. However, to achieve these high performance levels, improvements are needed in the thermal and structural properties for arm...

Advanced, waveform based acoustic emission (AE) techniques have been developed to evaluate damage mechanisms in the testing of composite materials. This approach, more recently referred to as Modal AE, provides an enhanced capability to discriminate and eliminate noise signals from those generated by damage mechanisms. Much more precise source location can also be obtained in comparison to conv...
