    摘要： There is provided a system that uses a network matrix to carry out a search for shortest paths from a starting node included in a network having a plurality of nodes to other nodes. The network matrix includes link costs of links and each link has a root end that is a node included in the network and a tail end that is another node connected to the root end. The system includes a processor that includes a circuit for subtracting a lowest value from link costs of the subject links being searched that are included in the network matrix, a circuit for setting tail end node of a link out of the subject links whose link cost has become zero due to the subtracting as a reached node, a circuit for changing link costs of links included in the network matrix whose tail end nodes are the reached node to a value indicating exclusion from further search, and a circuit for setting values after the subtracting of link costs of the subject links whose link costs do not become zero due to the subtracting as link costs of links for a continued search.

    摘要： In an access network using optical switches, communications between an OLT and ONUs are established without a photoelectric conversion performed at an optical switching unit.The OLT controls the downlink optical switch SW(DOWN) to sequentially select each ONU in slots arranged in a discrete manner, and transmits a Discovery Gate message. Upon receipt of the Discovery Gate message, each ONU consecutively transmits Register Request messages. The uplink optical switch SW(UP) sequentially switch signals from ONU#1 through ONU#128 in the slots arranged in a discrete manner, and outputs the signals to the OLT, Some of the Register Requests transmitted from the respective ONUs pass through the SW(UP), and reach the OLT. Based on the received Register Requests, the OLT determines the timing of transmission for the ONUS, and notifies the ONUS of the timing of transmission through a Gate message.

    摘要： An object can be displayed on a screen of a two-dimensional coordinate system based on xyz-coordinate values of the object in a three-dimensional coordinate system, operation information of a two-dimensional coordinate system with respect to the object can be received from an input device, and whether the operation information is in accordance with a predetermined rule or not is determined. If the operation information is not in accordance with the predetermined rule, xy-coordinate values of the object can be updated in accordance with the operation information. If the operation information is in accordance with the predetermined rule, a z-coordinate value of the object can be updated in accordance with the operation information.

    摘要： Technologies are generally described for providing an encryption method using real-world objects. In some examples, a method may include capturing, by a first electronic device, an external object, generating an object signal associated with the external object, generating an encryption key based on the object signal, and transmitting data encrypted by the encryption key to a second electronic device.
