Abstract: A cluster generation apparatus includes a control unit which executes: a user information acquisition step of acquiring items of position information on a plurality of users and items of time information; and a first cluster generation step of detecting, using the items of position information on the users, types of spots visited by the users and generating first clusters based on a commonality of the types of the spots visited, the first clusters being classifications of the users.

Abstract: A cluster generation apparatus includes processing circuitry configured to acquire position information and time information for a plurality of users; generate a cluster based on spots visited by the users by using the position information for the users, the cluster being a classification of the users; and generate, for each generated cluster, a movement route based on a history of movement of the cluster between the spots, from the time information and the position information for the users belonging to the cluster.

Abstract: An assembly of nanoparticles includes metal oxide, the nanoparticles including zinc (Zn) and silicon (Si). In addition, the nanoparticles have an atomic ratio of Zn/(Zn+Si) in a range of 0.3 to 0.95. Further, the nanoparticles have an equivalent circular particle diameter in a range of 1 nm to 20 nm.

Abstract: A radio-wave transmitting substrate includes a dielectric substrate, and, on at least one main surface of the dielectric substrate, a heat-ray reflection film including an electroconductive film, and an opening where the electroconductive film is absent in a plan view. At least a part of the at least one main surface in a plan view is a radio-wave transmitting region. The radio-wave transmitting region is a region where every 1-cm square unit region in the region satisfies the following expression (a): L>802.6×S?503.7. L is an overall length (unit: mm/cm2) of a boundary between the heat-ray reflection film and the opening in the unit region, and S is a proportion of an area occupied by the heat-ray reflection film in the unit region.

Abstract: A glass article which has: a glass plate having a contour shape having an upper edge and a lower edge; a functional film formed on at least one of principal surfaces of the glass plate; and a holder having a recessed portion into which the lower edge of the glass plate is fitted, wherein the functional film has a first coverage area and a second coverage area, the second coverage area being formed in a manner to cover the principal surface, the first coverage area being formed on a lower side of the second coverage area, and a maximum film thickness of the first coverage area being smaller than a maximum film thickness of the second coverage area, and the holder is provided on a lower edge side of the glass plate, within the first coverage area of functional film, via an adhesive in the recessed portion.

Abstract: There are provide a liquid composition for forming a silicon oxide-based cured coating film by the sol-gel method, the liquid composition having excellent storage stability and being capable of forming a coating film excellent in durability, in particular, alkali resistance even after long-term storage. A liquid composition applied on a surface of a substrate and cured by heating to form a coating film, contains: a matrix component containing a hydrolyzable silicon compound whose content is 20 to 60 mass % as a SiO2 content when silicon atoms contained in the matrix component are converted into SiO2 to the total solid content amount in the liquid composition; a functional component containing an ultraviolet absorbent and an infrared absorbent; water; and an acid thermally decomposing at 80° C. or higher and a temperature of the heating or lower, wherein a pH increases between before and after the thermal decomposition of the acid.
