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.

Abstract
Noise-proof digital systems were developed for processing, transfer and input into computer of a secondary electron emission signal with visualization of welding processes in real-time mode. The equipment was developed for conversion, transfer and processing of the secondary electron emission signal, namely block of processing, conversion and transfer of the secondary electron emission signal; block of input and decoding of the digital electron secondary emission signal; block of processing, conversion and transfer of the secondary electron emission signal via Ethernet. Video monitoring systems using the equipment for conversion and transfer of the signal and equipment for conversion and information transfer into computer were developed and tested. Software was designed. The investigations of developed video monitoring system were carried out, their comparative analysis with video monitoring system RASTR, widely used in the units for electron beam welding, were performed. 6 Figures.
