Abstract: A dose monitor measures a dose of a beam. The position monitor measures the beam size of the beam. The irradiation control apparatus calculates the measurement characteristic of the dose monitor based on the dose and the beam size of the beam, and controls the irradiation of the patient with the beam based on the measurement characteristic and the dose.

Abstract: The present invention enables comparison of the number of data items between groups.

Abstract: Disclosed is a communication system having two or more communication terminals. The communication system has: an attitude state detecting means which detects the attitude state of each of the communication terminals; a relationship calculating means which calculates the attitude state relationship between the communication terminals, on the basis of the communication terminal attitude states detected by the attitude state detecting means; and a communication policy determining means which determines, on the basis of the attitude state relationship between the communication terminals, a communication policy to be applied to between the communication terminals.

Abstract: The present invention enables comparison of the number of data items between groups.

Abstract: An appropriate index value for guaranteeing the anonymity of data is specified, even when the data number of data included in a predetermined group increases and decreases with time.

Abstract: It is an object of the present invention to enable appropriate generalization of attribute information even when data sets are likely to be repeatedly provided and attribute information of a data entry added later substantially deviates from a range of values of attribute information of a known data entry. For each data entry of a data set having a plurality of data entries each including at least one attribute data forming a quasi-identifier, which is information that can identify an individual, and at least one attribute data other than the quasi-identifier, a value of the at least one attribute data forming the quasi-identifier is generalized on the basis of a predetermined generalization rule.

Abstract: The present invention controls access to information so that the burden upon the owner of the information is reduced. The access control device of the present invention includes a relationship information generation unit for generating relationship information including relationship among users on the basis of object information related to a first user and object information related to a second user, a relationship storage unit for storing the relationship information, and an access assessment unit for assessing the control state of access requested to the second user from the first user on the basis of the relationship information stored by the relationship storage unit.

Abstract: A fluidized-bed gasification furnace has a gasification chamber for fluidizing a fluidized medium therein and pyrolyzing a material in the fluidized medium to produce a pyrolysis gas and a pyrolysis residue. The fluidized-bed gasification furnace also has a combustion chamber having a combustion portion for fluidizing a fluidized medium therein and combusting the pyrolysis residue to heat the fluidized medium and a settling portion disposed adjacent to the combustion portion and the gasification chamber for settling the heated fluidized medium therein.
