The acquisition unitB acquires sales request information S, which is request information regarding a sale of data owned by a data owner, from an owner terminalused by the data owner. The determination unitB determines, on a basis of the sales request information S, whether or not there is a customer who demands the data. The notification unitB notifies, in a case where the determination unitB determines that there is the customer, the owner terminalof sales response information Sindicating information regarding the customer for the data.

Provided is an information provision system that can provide workers with useful information for combining tables, so that even workers with little specialized knowledge can smoothly proceed with the task of combining multiple tables. An input unitreceives input of multiple tables. An identification unitidentifies a pair of columns that are in a combinable relationship, identifies that a pair of tables to which the individual columns forming the pair belong is the pair of tables to be combined, and identifies a combine method of the tables to be combined. An output unitoutputs the pair of tables to be combined, the pair of columns in a combinable relationship, and the combine method of the tables to be combined.

Provided is a tensor decomposition processing system capable of comprehensively finding factors obtained by tensor decomposition on a given tensor. A decomposition execution unitexecutes tensor decomposition on a given tensor a plurality of times until a predetermined end condition is satisfied. A condition determination unitdetermines whether the predetermined end condition is satisfied. When executing the tensor decomposition on the tensor, the decomposition execution unitexecutes the tensor decomposition under a constraint of obtaining factors different from factors obtained by previous execution of the tensor decomposition.

An impact range estimation apparatusestimates a range of impact due to infection by malware in a network system with a plurality of nodes. The impact range estimation apparatusincludes: a reverse propagation probability calculation unitconfigured to, when a specific node is infected with the malware, based on scenario information that specifies a pattern of attack by the malware and a communications log in the network system before infection by the malware, for each node other than the specific node, calculate a probability that the malware propagates from that other node to the specific node; and a simulation execution unitconfigured to, using the calculated probability, execute a plurality of times a simulation in which the malware is propagated to the specific node, and for each other node, calculate a number of times that that node becomes a propagation source of the malware.

Impact range estimation apparatus, impact range estimation method, and computer-readable recording medium

When spot-welding a workpiece including a thin plate, a first thick plate, and a second thick plate, the workpiece is clamped by a fixed electrode in contact with the second thick plate, a movable electrode in contact with the thin plate, and control-pressure applying unit set adjacent to the movable electrode and in contact with the thin plate. Pressure is applied to the second thick plate by the fixed electrode, and pressure and control pressure are respectively applied by the movable electrode and the control-pressure applying unit to the thin plate. The pressure from the fixed electrode is controlled to be smaller than the pressure from the movable electrode. The current density between the thin plate and the first thick plate increases.
