摘要:
Packet transmission quality in a communication network is measured by transmitting a measurement packet from a packet transmission node to a packet reception node. The packet transmission node is provided with a transmission counter counting the number of packets transmitted from a packet transmission node to a packet reception node, and a measurement packet counter counting the number of measurement packets transmitted from the packet transmission node to the packet reception mode. The packet reception node is provided with a reception counter counting the number of packets received from the packet transmission node. The packet transmission node transmits a measurement packet including a transmission counter value and a measurement packet counter value, to the packet reception node which calculates the number of lost packets or a loss rate of packets on the basis of the transmission counter value, the measurement packet counter value, and a reception counter value.

摘要:
An address translator of a first communication station transmits to a second communication station a transmission frame that is sent from a terminal in the first communication station to a terminal in the second communication station and includes the virtual private address of the terminal, after the address translator translates the virtual private address into a corresponding real private address, while it determines the global address of the second communication station based on the virtual private address and applies it to the frame. The address translator of the second communication station that received the frame sends a content of the transmission frame to the terminal indicated by the real private address included in the transmission frame.
摘要:
A surface discharge type plasma display panel(PDP) includes a pair of front and rear substrates (11, 21) with a discharge space (30) therebetween and a plurality of pair display electrodes on internal surface of either the front or rear substrate. The display electrodes are extending along each display line L. The PDP further includes a light shielding film (45), having a belt shape extending along the display line direction, formed on either internal or outer surface of the front substrate (11) to overlap each area S2 between the adjacent display lines L and sandwiched between the display electrodes X and Y.

A plasma display device is provided that can realize a stable progressive display using a plasma display panel that has a shared type arrangement form of display electrodes. A plasma display panel structure including display electrodes having a shape that has little variation of electrode area between cells and a driving sequence are combined in which the addressing step is divided into the first half and the second half. One of the first half addressing and the second half addressing is performed for a row on which the first display electrode is arranged that has an odd arrangement order when noting only the first display electrodes that are not used for row selection, and the other of the first half addressing and the second half addressing is performed for a row on which the first display electrode is arranged that has an even arrangement order.

A learning control system according to the present invention is one which performs learning of action values of actions in an apparatus which identifies its state as one of predetermined states, and selects an action based on the obtained action values and the identified state. The learning control system includes n action value learning devices including the first to the n th learning devices which perform learning of n action values from Q1 to Qn, assuming that n is a positive integer and an action value determining device which determines the total action value of an action Q of each state based on outputs of the n action value learning devices. In the learning control system, the first target value of the first action value learning device is determined based on the reward r obtained after an action has been carried out by the next state and a total action value Q′ that was prepared for the action selection in the next state, and the first learning device updates the first action value Q1 using the first target value. When n is 2 or more, the n-th a target value of the n th action value learning device is set to the difference between the (n−1) th target value of the (n−1) th learning device and the action value Qn-1, and the n th learning device updates the n th action value Q1 using the n th target value.
