Abstract: An analysis method for carrying out an analysis for responses of a computer system including a plurality of servers, includes: obtaining data concerning a CPU utilization ratio of each of the plurality of servers from the computer system, and storing the data concerning the CPU utilization ratio into a CPU utilization ratio storage; obtaining processing history data generated in the computer system, generating data of a request frequency by users of the computer system, and storing the processing history data into a request frequency data storage; and estimating an average delay time in each server by using the CPU utilization ratio of each server, which is stored in the CPU utilization ratio storage, and the request frequency stored in the request frequency data storage, and storing the estimated average delay time into a server delay time storage. By carrying out such a processing, the analysis can be carried out without changing the computer system to be analyzed and any additional cost.

Abstract: A turbine exhaust system includes an exhaust hood inner casing that involves the turbine rotor; an exhaust hood outer casing that forms an exhaust hood, together with the exhaust hood inner casing; a flow guide that forms an annular diffuser flow path; and exhaust hood upper part flow guides each of which serves as means for separating annular plane upper part exhaust steam within a range including a vertical upward flow out of exhaust steam radially discharging from the flow guide into the exhaust hood, from other exhaust steam, to thereby introduce the separated steam to the condenser, wherein exhaust steam introduction-side end faces thereof are located further toward the upper side than the horizontal plane containing the central axis of the turbine rotor.

Abstract: A distributed application system has a plurality of applications running on a plurality of servers arranged hierarchically and, when receiving a request telegraphic message from a client, executes processes while transferring a relay code between applications in order. A trace condition embedding unit embeds a trace collection condition into a relay code and transfers it to the next application. When the request telegraphic message is received, trace collection units decide whether trace collection is to be made or not based on the trace collection condition of the relay code, in other words, based on the switch information which indicates whether trace collection is to be made or not to perform a process. The trace collection condition includes a function ID which indicates a range of tracing for each application and a relay ID which records applications which has been passed through.

Abstract: The system of the present invention gives a load to a computer system according to load parameter specification from a system administrator, measures a response and a throughput while giving the load to the computer system, then measures a resource situation of each resource while the load is given. Then, it determines load monitoring conditions relating to a monitoring point, a monitoring item and a threshold from results of measuring the response and throughput and the results of measuring the resource situation and performs load monitoring on the determined load monitoring conditions.

Abstract: A single-flux-quantum digital device includes a first superconducting line extended in a large ring, a second superconducting line connected to the first superconducting line, a superconducting single electron transistor for regulating a supercurrent flowing through the second superconducting line, and a small tunnel junction device for detecting a change in the supercurrent flowing through the first superconducting line. The first superconducting line is extended in a large ring. The second superconducting line divides the large ring into two small rings which are substantially the same in shape and area. The small tunnel junction device is connected to a point where the first and the second superconducting line are joined.

Abstract: A simulator includes a model generation/management section that generates and manages a model corresponding to a system to be simulated; a scenario generation/management section that prepares a future-forecasting scenario for verifying a state that the system does not satisfy a predetermined performance standard in future, and at the same time, prepares a design-supporting scenario for verifying a state that the system satisfies the predetermined performance standard; a simulation engine that executes a simulation corresponding to the future-forecasting scenario or the design-supporting scenario; and a simulation control section that controls a simulation corresponding to the design-supporting scenario or the future-forecasting scenario based on a result of a simulation of the future-forecasting scenario or the design-supporting scenario.

Abstract: The simulator is provided with a control section that gathers the parameters of a plurality of parts in a computer network and that thereby predicts a future state of the computer network over a prescribed period of time. Further, a scenario creation/management creates a model corresponding to the computer network. Finally, simulation engine executes the simulation on the basis of the created model.

Abstract: A pair of static induction thyristors, which are coupled in parallel in the opposite bias directions between an AC power source and a load, is turned on by a light signal and is turned off by natural commutation, a light signal or an electric signal. The turn-off light signal is generated within a phase angle of 90.degree. in the time axis around the zero-cross point of the AC voltage from the AC power source.
