Abstract: Combining a plurality of local flow measurements made at more than one location to generate a composite flow value can improve the accuracy of the overall measurement. The reliability and long term accuracy of a multi-sensor flow measurement are improved by a two-step process. During an initial learning period, when all of the local sensors are providing accurate local measurements, a calibration table is built up that associates each calculated composite flow value with the set of local flow signal values from which it was calculated. In a subsequent operational period each time the composite flow rate is to be determined the flow meter apparatus first checks to see if all the local sensors are working properly and, if one of them is not working properly, its output is replaced with the corresponding value from the calibration table.

Abstract: The system provides a technique for detecting changes in behavior of a computer system. An address data storing unit obtains an address being accessed by a CPU at prescribed sampling intervals, stores address data comprising the address and its acquisition time in an address record table in time series. Then an executed process detector detects the name of the process that was executed when the address data was obtained, and sets the process name for the address data in the address record table. When an analysis request specifying an analysis time period is made, an analyzer counts up each of the process names included in the address data being stored in the address record table for each specified analysis time period, and analyzes the breakdown of executed processes for each analysis time period. Then a display unit displays the analysis result of the analyzer.
