Abstract: A wireless communication method collects data generated from a plurality of moving entities. The wireless communication method includes performing first communication in which a control device controls a condition of data forwarding in the plurality of moving entities, via long-distance wireless communication; performing second communication that includes carrying out communication between one of the moving entities and a relay, or communication among the plurality of moving entities, via short-distance wireless communication, by using a DTN (Delay Tolerant Network), which employs a store-carry-and-forward process; and performing third communication that includes carrying out communication between the control device and the relay, or communication between the control device and one of the moving entities, via wired communication or the long-distance wireless communication.

Abstract: [Object] To provide a network visualizing apparatus giving a user to have a clear perspective of network configuration and operation. [Solution] The visualizing apparatus for monitoring a network having logical configuration changeable by software interpreting a network control command includes a display device 98, a first drawing unit drawing a first image 92 representing cooperation between services provided on the network on the display device 98, and a second drawing unit drawing a second image 98 representing what connection between which node and which switch realizes the service cooperation on the network, on the display device. The first and second drawing units update drawings of a service cooperation execution monitoring window 92 and a network configuration monitoring window 98, respectively, in a synchronized manner.

Abstract: A system for treating waste water using a particulate body formed by covering and fixing nitrifying bacteria. In the system, the particulate body is inserted in a nitrifying vessel which including therein an air diffusion device for supplying oxygen to the nitrifying bacteria and a particulate body separation device for preventing the outflow of the particulate body. The nitrifying vessel and the particulate body contained therein are used as a nitrifying vessel unit and one or more such nitrifying vessel units are arranged within a treating tank. Waste water is circulated between the nitrifying vessel and the other portions of the treating tank than the nitrifying vessel by means of the air lift effect of the air diffused from the air diffusion device.
