Abstract: An apparatus specifies, for each of interfaces described in a source code, an installed program associated with the each interface, based on a description of the source code including a relevant source code corresponding to the installed program, and stores an identifier of the specified installed program in the memory in association with an interface associated with the installed program. The apparatus specifies an interface to be executed upon execution of a program based on the source code, according to contents defined in the source code. The apparatus, upon execution of the program based on the source code, outputs information on the installed program whose identifier is stored in the memory in association with the specified interface, so that the installed program is identifiable.

Abstract: A grouping apparatus acquires a plurality of messages output from a plurality of output source apparatuses, respectively. The grouping apparatus acquires a plurality of explanatory texts respectively relating to the plurality of messages, from documents respectively relating to the output source apparatuses. The grouping apparatus generates a plurality of message groups that include related messages respectively, based on the plurality of explanatory texts for the respective messages.

Abstract: An execution-target program is executed, via a program-execution control program, by converting a byte code in the execution-target program into a native code based on a predetermined condition. Upon activating the execution-target program, it is determined whether the execution-target program is an optimization-completed program having a past record of having been converted into an optimized state of the execution-target program, based on a profile including information identifying the optimization-completed program and optimized-code information indicating an optimized code for the optimization-completed program, where the profile is updated at a timing of executing the program-execution control program or another program-execution control program, and the optimized code is generated by converting a byte code into a native code.

Abstract: A variable reluctance angle sensor includes a stator, a rotor, and a computation section. The stator includes a core member having teeth, which are arranged in a circumferential direction, and excitation coils, which are respectively wound about the teeth such that magnetic poles of the teeth have different polarities alternately in the circumferential direction. An input voltage is supplied to the excitation coils. The rotor radially faces the teeth of the stator. The rotor has a shape such that gap permeance with respect to the stator changes in a sinusoidal fashion in accordance with the rotational angle of the rotor. The computation section obtains output voltages of two or more phases having different phases based on the voltages of the excitation coils, and detects the rotational angle of the rotor based on the output voltages.

Abstract: A load balancing method for servers including allocating a job to one or more servers, respectively, having a load lower that a first reference value, upon detection of a first server having a load that is higher that the first reference value and is lower that a second reference value, reducing a load of a second server having the lowest load among the servers by a load balancing, and upon detection of any server having a load that is higher that the second reference value, reallocating a job of the any server to another server having the lowest load among the servers.

Abstract: A simulator machine obtains IDL information from an IDL definition storage, and automatically builds up a function of a server application or a client application based on the IDL information obtained. The simulator machine is connected to a WWW server that is one of nodes. Each of the rest of the nodes can access the WWW server by starting a WWW Browser thereby to build up on its own node a function of a server simulator or a client simulator that is provided by the simulator machine.
