Two methods that use advanced control technology in order to improve the performance of AC servomotor systems are described. The first method is the detection of instantaneous speed using an observer. This method provides good response in speed control because it is possible to detect exactly the speed without detection dead time over a wide range of(More)
Land cover classification in Kitami, which covers an area of 12 km X 9.6 km, was done using Landsat TM data immediately after geometric correction. For each of seven land cover categories, monthly mean albedo was estimated based on field measurements obtained by the Cold Region Meteorological Observation System (CRMOS) of the Kitami Institute of Technology(More)
