Abstract: A method and multi-scale attention system for the detection of objects and temporal change regions by a spatiotemporal attention operator of an image sequence, which linearly aggregates temporal change filter with spatial saliency filter and includes an extractor of salient maxima, which selects consecutive salient maxima of the spatiotemporal operator to produce the locations of the objects of interest and the centers of temporal change regions. The concept of spatial local scale introduced into the system and method for its determination allows for a scale-adaptive integration of the temporal change with spatial saliency and effective detection of different in size and location objects of interest. Can be used for object and spatiotemporal change detection in monitoring pollution, natural disasters, weather conditions and environmental changes based on satellite remote sensing imagery from various sensors.

Abstract: A flame-photometric detector burner of a gas chromatograph employing a system of two nozzles arranged in relation to each other for securing mutual flame jump-over from one nozzle onto the other one, and vice versa. One nozzle is designed to supply carrier gas with the substance to be analyzed, and the other is designed to only supply an oxidizer. The outlets of both nozzles are arranged within a hydrogen stream in a cavity of a combustion chamber of a detector block. The nozzle where only the oxidizer is supplied can be electrically insulated from the detector block, and connected to a high-voltage source.
