摘要： A sound source separation program causes a computer to acquire an acoustic signal, convert the acquired acoustic signal from a time region to a frequency region, and perform sound source separation on the acoustic signal converted to the frequency region by performing updating based on elementary row operation on a demixing matrix to iteratively minimize an objective function including a quadratic form of a separation vector and a determinant of the demixing matrix.

摘要： Provided is a combustion system using a catalyst having better denitration efficiency at low temperatures, during a selective catalytic reduction reaction in which ammonia is used as a reducing agent.
This combustion system comprises: a combustion device that combusts fuel; an exhaust path through which flows exhaust gas generated from the combustion of fuel in the combustion device; a dust collection device that is arranged on the exhaust path and collects ash dust/dust in the exhaust gas; and a denitration device that is arranged on the exhaust path and removes nitrogen oxides from the exhaust gas by means of a denitration catalyst, wherein the denitration device is arranged downstream of the dust collection device on the exhaust path, and the denitration catalyst contains vanadium oxide including vanadium pentoxide and has a defect site in which an oxygen atom is deficient in a crystal structure of the vanadium pentoxide.-

摘要： A water vapor distribution measurement apparatus comprises: a light source that emits near-infrared light; a near-infrared light measurement device that is located across a measurement space from the light source and that measures the near-infrared light; an optical system that expands and applies the near-infrared light emitted from the light source in the measurement space in which a cross-section of the measurement space perpendicular to a direction connecting the light source to the near-infrared light measurement device has an area; and a distribution deriving means for deriving a water vapor distribution in the cross-section of the measurement space on the basis of a measurement result obtained by the near-infrared light measurement device. Water vapor in a measurement region having a prescribed size can be measured by this water vapor distribution measurement apparatus.
