In this paper, a new method is proposed for calibrating a planar array of general geometry with respect to errors in location, phase and gain, even when all errors are present simultaneously (global calibration). The method requires the use of three pilot sources, which operate one at a time and from at least two different azimuth angles. Since the sources need not operate simultaneously, one o...

alkaline phosphatase (ortho phosphate, monoester hydrolase phosphoinositide e. c. 3.1.3.1) is a non-specific metalloproteinase enzyme that is located inside periplasmic space of bacteria. this enzyme is used to measure freshwater sediment in genetic engineering for cleaning water. isolation and molecular identification of the bacteria producing alkaline phosphatase and comparison of its product...

Future air traffic management (ATM) decision support systems (DSS) rely upon trajectory forecasting to adequately deliver benefits. These forecasts are subject to errors from a variety of sources. As the number and sophistication of ATM DSS capabilities grow, the interoperability between DSS will become more sensitive to the magnitude and variation in trajectory forecasting errors across DSS. T...
