Abstract: In the case of a gas in which several gases are mixed, a type and concentration of the gas may be incorrectly measured when measured using only an optical band-pass filter. The invention of the present application is directed to providing a technology in which a plurality of broadband band-pass filters having overlapping regions are provided to calculate a magnitude of absorption for each wavelength band for light passing through each broadband band-pass filter, thereby identifying the presence of a gas of interest and the presence of a gas other than the gas of interest.

Abstract: A computing method for privacy-preserving data analysis is provided, in which the computing method is performed by at least one processor and includes receiving a data analysis request including data-to-be-analyzed from a client, homomorphically encrypting the data-to-be-analyzed using an encryption engine, and uploading the homomorphically encrypted data-to-be-analyzed to a target path of a blockchain, and then, the method includes, based on the request to check analysis result, decrypting an analysis result of the homomorphically encrypted data stored in a designated path of the blockchain by using the encryption engine, and providing the decrypted analysis result to the client, in which the analysis result of the homomorphically encrypted data is data analyzed by a worker linked to the blockchain, and stored in a designated path in association with the target path of the blockchain.

Abstract: A frame structure of a commercial vehicle having an independent suspension system may include: a front outrigger mounted at lower front ends of wheel housings along a wide direction of a vehicle; a rear outrigger mounted at lower rear ends of the wheel housings along the width direction, wherein the wheel housings are arranged between the front and rear outriggers in a vehicle body length direction; a center reinforce unit mounted on an inner lower side of the wheel housing and disposed between the wheel housings, the center reinforce unit configured to connect the front and rear outriggers along the vehicle body length direction; a side reinforce unit mounted on an inner side of the wheel housing and connected to the center reinforce unit; and a lower reinforce unit configured to be connected to the center reinforce unit and coupled to the first suspension mounting assembly through the rear outrigger.
