    摘要： One embodiment of the present invention provides a technique for detecting anomalies during operation of a test computer system. Initially, a golden system and the test system are equipped with the same hardware configuration, wherein the golden system has gone through extensive qualification testing and is presumed to be operating correctly. Next, a deterministic load is executed on the golden system, and values for performance parameters from the golden system are monitored while the deterministic load is executing. Similarly, the deterministic load is also executed on the test system, and values for performance parameters from the test system are monitored while the deterministic load is executing. Next, pairwise differences are computed between values for performance parameters received from the test system and values for performance parameters received from the golden system. Finally, change detection techniques are applied to the pairwise differences to detect anomalies during operation of the test system.

    摘要： Methods and systems for quantification of a target nucleic acid in a sample are provided. The method includes forming a plurality of discrete sample portions. Each of the plurality of discrete sample portions comprising a portion of the sample, and a reaction mixture. The method further includes amplifying the plurality of discrete sample portions to form a plurality of discrete processed sample portions. At least one discrete processed sample portion containing nucleic acid amplification reaction products. Fluorescence signals are detected from the at least one of the plurality of discrete processed sample portions to determine a presence of the at least one target nucleic acid. The method also includes determining the respective volumes of the plurality of the plurality of discrete processed sample portions, and estimating the number of copies-per-unit-volume of the at least one target nucleic acid in the sample. Estimating the number of copies-per-unit-volume is based on the number of discrete processed sample portions determined to contain the at least one target nucleic acid therein.
