Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The analysis of basic parameters of flash butt welding was carried out according to the data of current technological reports formed by the computer control system during welding of rails. The opportunity to develop the model for predicting the output quality index of welded butt of a rail, i.e. fracture load of specimen and deflection, was shown based on the parameters of welding process applying different methods of statistical analysis, in particular, correlation and regression analysis and neural networks. The calculations were carried out according to the experimental data obtained at the Kiev rail welding enterprise during welding of rails in the welding machine K1000. 6 Ref., 2 Tables, 5 Figures.
Keywords: flash butt welding, statistical models of monitoring and control, monitoring of process parameters, statistical control
