A data collection system includes a server device and at least one probe vehicle. The server device includes a storage unit configured to store a master map in which a necessity of data collection for each of a plurality of unit ranges included in a plurality of segments is represented by a binary value; and a server control unit configured to extract from the master map a segment corresponding to a position of the probe vehicle, and to transmit the segment to the probe vehicle as a partial map. The probe vehicle includes a data obtaining unit configured to obtain the data; and a vehicle control unit configured to identify a unit range requiring data collection based on the partial map received from the server device, and to transmit the data obtained in the unit range to the server device.

Data collection system and data collection method

The multi-agent simulation system includes a plurality of back-end servers provided for each of a plurality of service systems and a plurality of agent simulators provided for each of the plurality of agents. Each of the plurality of service systems provides a service used in the target world. The plurality of agent simulators are programmed to simulate a state of each of the plurality of agents while causing the plurality of agents to interact with each other by exchange of first messages. The plurality of back-end servers and the plurality of agent simulators are programmed to simultaneously simulate a plurality of services by exchanging second messages different from the first messages.

Multi-agent simulation system and method

The multi-agent simulation system includes a plurality of agent simulators provided for each of the plurality of agents and a center controller. The plurality of agent simulators are programmed to simulate a state of each of the plurality of agents while causing the plurality of agents to interact with each other by exchanging messages. The center controller is programmed to control a speed ratio of a flow of time in the target world to a flow of time in a real world. Each of the plurality of agent simulators calculates an index value corresponding to a remainder time rate. The remainder time rate is a rate of a remainder time to an update time interval for updating a state of a target agent to be simulated. The center controller controls the speed ratio based on the index value calculated by each of the plurality of agent simulators.

The multi-agent simulation system includes a plurality of agent simulators provided for each of the plurality of agents and a center controller. The plurality of agent simulators are programmed to simulate a state of each of the plurality of agents while causing the plurality of agents to interact with each other by exchanging messages. The center controller is programmed to manage participation of the plurality of agent simulators in a simulation of the target world and separation of the plurality of agent simulators from the simulation of the target world. The center controller separates an agent simulator whose processing does not keep up with a flow of time in the target world from the simulation of the target world.

A multi-agent simulation system performs a simulation of a target world in which a plurality of agents interacting with each other exist. The multi-agent simulation system includes: a plurality of agent simulators configured to perform simulations of the plurality of agents, respectively; and a center controller configured to communicate with the plurality of agent simulators. The center controller performs message filtering based on a distance between the agents. Specifically, the center controller sets a delivery frequency of the delivery message to be low between the agent simulators that perform the simulations of the agents distant from each other. A space of the simulation target world is divided into a plurality of partitions, and the message filtering is performed in units of the partition.

A data transmission device that transmits data to another node, the data transmission device including: data storing unit for storing data; summary information storing unit for classifying data stored in the data storing unit into prescribed groups and for storing summary information that represents the number of pieces of data for each group; receiving unit for receiving summary information from the other node; selecting unit for selecting data to be transmitted based on the summary information received from the other node; and transmitting unit for transmitting the data selected by the selecting unit. The selecting unit favorably preferentially selects data included in a group with a smaller number of pieces of data based on the summary information received from the other node. Due to such a configuration, information with a high possibility of not being possessed by a communication partner can be selected and transmitted in a data sharing system.

A travel time information providing apparatus includes a probability distribution storage unit configured to store first probability distribution data which expresses an embarkation waiting time for each location where the waiting time occurs and second probability distribution data which expresses a travel time for each location where the travel time occurs; a route acquiring unit configured to acquire a route connecting a point of origin and a destination; a travel time calculating unit configured to calculate a probability distribution of a total travel time by convoluting all probability distribution data corresponding to an embarkation waiting time which occurs on the route and a travel time which occurs on the route; and an information providing unit configured to determine an estimated travel time based on the calculated probability distribution, and output the estimated travel time.

A process for separating an electrodeposited metal from a cathode plate in electrolytic refining is disclosed. The cathode plate on which the metal is electrodeposited is first held. Then, heated air is blown toward the cathode plate and the electrodeposited metal thereon. As a result, the electrodeposited metal is separated from the cathode plate. An apparatus for carrying out the same process is also disclosed. The apparatus includes a separating furnace, a holding assembly, and a device for introducing heated air into the separating furnace. The holding assembly is attached to the separating furnace for holding the cathode plate in the furnace. The heated air-introducing device introduces heated air, blowing it against the cathode plate, whereby the electrodeposited metal is separated from the cathode plate.
