Abstract: In a system management apparatus, a failure detection unit detects a readout failure in one of blocks constituting distributed data stored in a first RAID disk array. A request unit requests a computer to supplement one of the blocks of the distributed data stored in the first RAID disk array in which a readout failure irrecoverable by use of only the data stored in the first RAID disk array occurs, where the computer has a second RAID disk array storing a duplicate of the distributed data stored in the first RAID disk array. And an overwriting unit receives data corresponding to the one of the blocks from the computer, and overwrites the one of the blocks with the received data.

Abstract: A parts management method is performed by a parts management device for managing parts used to produce an assembly product. Firstly, parts identification information and number of parts corresponding to an assembly product of which production is started are read from a storage device, respectively, as used-parts identification information and a used number. Secondly, parts container information of a parts container that accommodates parts used for an assembly product of which production is started is read from a storage device that stores parts container information, for each parts container. Then, parts container information that includes an updated number of parts is written into a storage device. The updated number of parts is obtained by subtracting the number of used parts from number of parts identified by the used-parts identification information read in the firstly reading.

Abstract: In a multiple-input multiple-output transmission system (MIMO system), a receive station detects whether or not there is an error in each data stream, estimates the state of the propagation path of each transmit antenna and reports, to the transmitting side, re-transmission necessary/unnecessary information, for every data stream, created based upon whether or not there is an error, and the state of the propagation path of each transmit antenna. A transmit station decides a transmit antenna that transmits a data stream requiring re-transmission, based upon the reported state of the propagation path of each transmit antenna, and re-transmits the data stream requiring re-transmission from the transmit antenna decided.
