Abstract: 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.

Abstract: An economical optical network is constituted by effectively using network resources by using the minimum number of, or minimum capacity of 3R repeaters. 3R section information corresponding to topology information on the optical network to which an optical node device itself belongs is stored, and the 3R section information stored is referred so as to autonomously determine whether or not the optical node device itself is an optical node device for implementing the 3R relay when setting an optical path passing through the optical node device itself. Alternatively, when the optical node device itself is a source node, another optical node device for implementing the 3R relay among the other optical node devices through which the optical path from the optical node device itself to the destination node passes is identified, and this identified optical node device is requested to implement the 3R relay when setting an optical path in which the optical node device itself is a source node.

Abstract: Implementations and techniques for outputting information about estimated QoEs on a terminal on which plural applications can be executed are generally disclosed. The estimated QoEs may be obtained by performing QoE estimation on an application basis.

Abstract: 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.

Abstract: A pipeline-based matching scheduling approach for input-buffered switches relaxes the timing constraint for arbitration with matching schemes, such as CRRD and CMSD. In the new approach, arbitration may operate in a pipelined manner. Each sub-scheduler is allowed to take more than one time slot for its matching. Every time slot, one of them provides a matching result(s). The sub-scheduler can use a matching scheme such as CRRD and CMSD.

Abstract: A Pipelined-based Maximal-sized Matching (PMM) scheduling approach for input-buffered switches relaxes the timing constraint for arbitration with a maximal matching scheme. In the PMM approach, arbitration may operate in a pipelined manner. Each subscheduler is allowed to take more than one time slot for its matching. Every time slot, one of them provides the matching result. The subscheduler can adopt a pre-existing efficient maximal matching algorithm such as iSLIP and DRRM. PMM maximizes the efficiency of the adopted arbitration scheme by allowing sufficient time for a number of iterations. PMM preserves 100% throughput under uniform traffic and fairness for best-effort traffic.
