An air quality satisfaction calculation unit (120) acquires a carbon dioxide concentration of the space, decides a constant that takes a different value in accordance with the carbon dioxide concentration, and calculates satisfaction with the air quality as an air quality satisfaction (31) by using the specific enthalpy and the constant. The air quality satisfaction calculation unit (120) calculates, as the air quality satisfaction (31), a value obtained by adding a second constant to a value obtained by multiplying the specific enthalpy by a first constant.

Abstract

A heart rate information concealed video transmission device includes a transmitter and a receiver. The transmitter compresses an input video and transmits the compressed video to a network, and the receiver decodes a received compressed stream, and attempts heart rate estimation by rPPG and generation of a biometric identifier. In order to invalidate heart rate estimation by a biological information processor, a corrected video generator outputs a corrected video in which small temporal variation of the input video is suppressed.

Abstract

A video super-resolution device includes a down-sampler, video super-resolvers, and a selecting/averaging unit. The down-sampler divides an input low-resolution video into a plurality of frame rates. The video super-resolvers are video super-resolvers trained at different frame rates, and perform super-resolution of the low-resolution video. The selecting/averaging unit selects a video super-resolver according to the magnitude of an optical flow obtained as a result of video super-resolution. Specifically, in a case where the optical flow has a value smaller than 0.5 pixels, the selecting/averaging unit makes selection such as not adopting a result of video super-resolution at a high frame rate. Finally, the selecting/averaging unit obtains a mean value of the selected video super-resolution result, and outputs a final high-resolution video.

Abstract

In order to solve a combinatorial optimization problem having a linear equality constraint by using an Ising model represented by multiple spin variables: a classical computer (20) selects at least one of the multiple spin variables as a first spin, sets the spins other than the first spin as second spins, represents the first spin as a linear expression of the second spins on the basis of the linear equality constraint, and thus defines a Hamiltonian of the Ising model as a function of the second spins, the Hamiltonian being expressed as the sum of an objective function term and a constraint term; and an Ising machine (30) calculates an optimal solution to the Hamiltonian. The classical computer (20) calculates an optimal solution of the Ising model by calculating a value of the first spin on the basis of the linear expression of the second spins from the optimal solution calculated by the Ising machine (30).

Abstract

Provided are: a fiber Bragg grating element in which a fiber Bragg grating whereby optical power loss is suppressed is formed in a narrow-diameter region; and a method for producing the fiber Bragg grating element. A starting fiber 31 in which a core 21 and a cladding 22 are each formed from quartz glass containing a photosensitive material is prepared. In the starting fiber 31, Ge (germanium) which increases the refractive index is used as the photosensitive material and the refractive index of the core 21 is made higher than that of the cladding 22 by increasing the concentration of the photosensitive material 21 in the core 21 so as to be higher than in the cladding 22, and said starting fiber 31 is heated and stretched to produce a tapered optical fiber 11. A narrow-diameter region 12 of the tapered optical fiber 11 is irradiated with ultraviolet rays by means of a phase-mask method and periodic refractive index modulation is formed in the core 21 and the cladding 22.

A specific enthalpy calculation unit (110) acquires the temperature and humidity of the space and calculates the specific enthalpy of the space. An air quality satisfaction calculation unit (120) acquires the carbon dioxide concentration of the space, determines constants that take different values depending on the carbon dioxide concentration, and uses the specific enthalpy and the constants to calculate an air quality satisfaction (31). The air quality satisfaction calculation unit (120) calculates the air quality satisfaction (31) by adding a second constant to the product of the specific enthalpy and a first constant.

The cancelling-load applying means includes: a pressing-force applying portion that applies a pressing force to the specimen as the canceling load; and a pressing-force determining portion that determines magnitude of the force. The pressing-force determining portion calculates the magnitude of the force using pre-stored equations so that an energy release rate related to in-plane shear mode crack deformation becomes zero.

The present disclosure provides a method for analyzing cells using a cell analyzer by utilizing the functions, either alone or in combination, of the cell analyzer, said cell analyzer having a function of continuously concentrating cells, a function of successively arranging the cells in a specific region of a flow channel continuously, a function of simultaneously recognizing the shape of each cell, in a single cell unit on an image base, in the bright field and the shape of fluorescence, and a function of separating and purifying the cells having been recognized on the basis of the shape thereof obtained by correcting the aforesaid shape in accordance with the flow rate of the cells and the light emission data of the fluorescence.
