We present a new edge detector for automatic extraction of oceanographic (mesoscale) features present in in-frared (IR) images obtained from the Advanced Very High Resolution Radiometer (AVHRR). Conventional edge detectors are very sensitive to edge fine structure, which makes it difficult to distinguish the weak gradients that are useful in this(More)
Computational materials science has evolved in recent years into a reliable theory capable of predicting not only idealized materials and device performance properties, but also those that apply to practical engineering developments. The codes run on workstations and even now are fast enough to be useful design tools. A review will be presented of the(More)

The paper presents the design principles, construction and test results for a double-cased calorimeter. The calorimeter is designed to measure power losses in the range from 100 W to 2.5 kW for air and water cooled power converters. The various challenges involved in measuring losses accurately are discussed. Improvements in the calorimeter design by(More)
