    Estimation of vehicle speed based on video analysis

    Trans Motauto World, Vol. 9 (2024), Issue 2, pg(s) 39-42

    The use of video cameras for automatic traffic management, as well as video surveillance cameras, has made it possible to visually observe traffic accidents, i.e. the manner and movement of the parties involved in the accident at the moment and immediately before it occurred. On the basis of a video of a vehicle passing through a section that can be photogrammetrically rectified and transformed into an orthogonal view, with knowledge of the dimensions of characteristic formations that are usually rectangular in shape, such as pedestrian crossings, etc., and with knowledge of the frequency of the video recordings, it is possible, using appropriate software, to determine the speed of the object under study. In this paper, the reliability of the speeds determined by rectification using the AnalyzerPro software has been compared with the target speeds of the vehicle defined by the speed limiter, measured by a handheld radar and a GPS device installed in the vehicle.

    Caprolactam distillation: implementation engineering solutions for rotary thin film evaporator

    Machines. Technologies. Materials., Vol. 16 (2022), Issue 1, pg(s) 33-37

    The paper proposes a reconstruction of the distillation of caprolactam for more complete removal of water from the finished product, removing the droplet phase during the process in thin-film evaporators, will improve the final product performance by eliminating the inappropriate indicators alkali content and the optical density of the final product and to ensure its stable high quality. The relevance of the work presented directions for improving the process of production of caprolactam – raw ingredient for the preparation of polymeric materials used in various sectors of the economy. Describes the causes affecting the quality characteristics of the finished products produced from caprolactam. the implementation the liquid distributor and the centrifugal separator would reduce 5 – 6 times droplet entrainment to ensure complete removal of moisture from the final product, will reduce the alkali content in the final product, reduce the rate of optical density and thus bring trademark caprolactam by indicators «alkalinity» and «optical density» to the level of the highest quality product.
