Abstract: A computer-implemented method for performing simulation includes establishing a mesh of a physical domain with nodes. The nodes represent a discretized physical quantity. The method accesses one or more different algorithms for evolving the nodes through sequential time steps. The method determines a unique combination of parameter values for each algorithm. In some examples, the parameter values can control dissipation, dispersion, and overshoot for each algorithm, as well as whether each algorithm is implicit or explicit. In some examples, the method can select one or more subsets of the nodes, and/or identify one or more time increments. The method can evolve the nodes in time, optionally using different time increments for different nodes in the mesh, and/or optionally using different algorithms for different nodes in the mesh. The method can optionally identify if an algorithm has failed to converge to a solution, and can switch to a different algorithm.

Abstract: A network information detection apparatus includes a packet monitoring section and a subnet mask detection section. The packet monitoring section monitors packets on LAN connecting a plurality of network devices. Based on an IP address included in at least one monitored packet, the subnet mask detection section detects a subnet mask of a network device having the monitored IP address. When a destination MAC address and a destination IP address included in the monitored packet do not indicate the same network device, a router of the LAN can be detected by detecting an IP address corresponding to the destination MAC address.

Abstract: An I/O-request processing system which is capable of reducing the maximum value of the time required until the I/O request of each external device is registered. An I/O-request receiving section (501) receives an I/O request issued from an external device (600). A process-information storage section (510) stores an I/O-request delay time (512) for each external device (600). A priority-process judgment section (520) registers the I/O request having a maximum I/O-request delay time (512) among the I/O requests which have been registered into an I/O-request cue (540).

Abstract: When a relay device receives a content transmitted from a first communication device toward a second communication device, the relay device performs relay processing of transmitting the content toward the second communication device. When, during the relay processing, the relay device receives a transmission request for the content, which has been transmitted from a third communication device toward the first communication device, the relay device performs transmission processing of transmitting a first section of the content, which has not been transmitted in the relay processing at a time of reception of the transmission request, from the relay device toward the third communication device in synchronization with transmission of the first section performed in the relay processing.

Subsequently, the semiconductor wafer is selectively etched so as to be separated into semiconductor elements. Then, the first conductive layer is connected to a ground potential to measure electrical characteristics of the semiconductor elements and sort the semiconductor elements into non-defectives and defectives. Then, the first conductive layer is selectively etched so as to be separated into chips and thus semiconductor pellets are formed. Finally, the second wafer holding substrate is peeled off.
