An acoustic feature estimation method is an acoustic feature estimation method for estimating an acoustic feature of a space and includes acquiring data on the space, estimating situations in the space in accordance with the acquired data, correcting a provisional value of the acoustic feature in accordance with the estimated circumstances, and outputting the corrected provisional value.

Provided are a residual stress estimation method and a residual stress estimation device capable of estimating residual stress suitable for a structure in which inherent strain occupied mainly by plastic strain occurs. A constraint condition is introduced to a distribution function used in the residual stress estimation method based on an inherent strain method, the constraint condition being that a plastic-worked structure does not undergo volume change before and after working. Residual stress or elastic strain is measured from a T piece collected from the structure, and a parameter of the distribution function is optimized so as to approximate the inherent strain at each measurement point obtained from the measured value of the residual stress or elastic strain. An estimated value of the residual stress in the structure is calculated using the obtained parameter.

Residual stress estimation method and residual stress estimation device

Provided is a residual stress estimation method and a residual stress estimation device capable of suppressing the number of cut pieces to be collected for measuring inherent strain without deteriorating residual stress estimation accuracy. In a case where it is assumed that the inherent strain is uniformly distributed in one direction in a structure, a user measures residual stress from a cut piece collected in a region in which the inherent strain is uniformly distributed and inputs the measured value to the residual stress estimation device. The residual stress estimation device estimates a two-dimensional inherent strain distribution on an analysis surface perpendicular to the one direction in the structure using the input residual stress measured value, transfers the estimated two-dimensional inherent strain distribution to the one direction, and estimates a three-dimensional inherent strain distribution in the structure.

Provided is a residual stress estimation method and a residual stress estimation device which are capable of setting an appropriate analysis range without depending on a user's experience. The residual stress estimation device displays analysis results in which strain generated in a structure is analyzed. A user determines a position and a size of an analysis range based on the analysis results, and inputs the determined position and size of the analysis range and a measured value of residual stress of a cut piece of the structure at a measurement point to the residual stress estimation device. The residual stress estimation device estimates distribution of inherent strain in the analysis range to approximate the inherent strain distribution obtained from the input measured value of the residual stress of the cut piece, thereby estimating the residual stress of the structure based on the inherent strain.

A purchase settlement method is provided. Voice information is acquired. A spoken command indicating a control instruction as to a device is obtained based on the acquired voice information. When the spoken command relates to purchase settlement, speaker information relating to a speaker who has spoken the acquired voice information is identified based on the acquired voice information. It is determined whether or not the identified speaker information is of a speaker permitted to perform purchase settlement by referencing a table in which speaker information of speakers permitted to perform purchase settlement and information necessary for purchase settlement are associated with each other. When it is determined that the identified speaker information is of the speaker permitted to perform purchase settlement, purchase settlement processing is performed using the spoken command and the information necessary for purchase settlement.

An information management method includes receiving an appliance identifier of an unregistered target appliance among at least one of appliances, a gateway identifier of a home gateway, and biological information regarding a user of the unregistered appliance, determining whether among the registered appliances associated with the gateway identifier, management information regarding at least one of the appliances associated with the user of the biological information is registered in a database, registering, if the determination is yes, the management information regarding the at least one of the registered appliances in the database as management information of the unregistered appliance in association with the user of the biological information, and sending, to an information terminal of the user, display information indicating that the management information regarding the at least one of the registered appliances is registered as management information of the unregistered appliance in association with the user of the biological information.

Information management method

A method capable of accurately measuring, in an object including a columnar shaft section and a tabular section projecting outward radially beyond an outer circumferential surface of the shaft section, a distribution of residual stress near a fillet surface interconnecting the shaft section and the tabular section. The method includes repeating a measurement cycle, which includes cutting the object to form a new cutting surface and measuring residual stress in a plurality of parts on the cutting surface. The cutting surface is a conical or cylindrical surface concentric with the axis of the shaft section, being through a reference position unchanged in the repeated measurement cycle. The reference position is desirably the center position of an arc of the fillet surface having the largest diameter on the central longitudinal cross-section of the object.
