Achievements in the area of automated ultrasonic control of quality of rails, solid-rolled wheels and tyres, wheels magnetic powder crack detection, carried out at JSC EVRAZ NTMK. The 100% nondestructive control is accomplished by automated control in series at two ultrasonic facilities RWI-01 and four facilities УМКК-1 of magnetic powder control, installed into the exit control line in the wheel-tyre shop. Diagram of location, converters displacement and control operations in the process of control at the facility RWI-01 presented, as well as the structural diagram of the facility УМКК-1. The automated ultrasonic control of rough tyres is made in the tyres control line of the wheel-tyre shop at the facility УКБ-1Д. The facility enables to control internal defects of tyres in radial, axis and circular directions of radiation. Possibilities of the facility УКБ-1Д software were shown. Nondestructive control of railway rails is made at two facilities, comprising the automated control line of the rail and structural shop. The УКР-64Э facility of automated ultrasonic rails control is intended to reveal defects in the area of head, web and middle part of rail foot by pulse echo-method with a immersion acoustic contact. The diagram of rail P65 at the facility УКР-64Э control presented. To reveal defects of the macrostructure in the area of rail head and web by mirror-shadow method, an ultrasonic noncontact electromagnetic-acoustic facility is used. It was noted, that implementation of the 100% nondestructive control into the technology of rolled stuff production enabled to increase the quality of products supplied to customers and to increase their competiveness.

The article is devoted to control and feedback in foreign language teaching in a technogenic environment. The educational process is transformed in terms of the implementation and active use of digital technologies. ICT-rich environment provides new models of interaction between the teacher, students and digital tools. It also enriches the diversity of tasks and expands the range of possible forms of control and feedback. According to the authors, automated evaluation takes place both in out-of-classroom activities and directly in the classroom using Bring Your Own Device technology (BYOD). Automated control contributes to the intensity of the educational process. It provides all the participants with an opportunity to choose a convenient mode of work and get instant feedback, thereby allowing self-assessment and self-reflection of their own actions. When teaching foreign languages, special attention should be paid to chatbot technology. Chatbots imitate human actions and are able to perform standard repetitive tasks. The growing popularity of bots is explained by a wide range of usage spheres and the ability to integrate chatbots into social networks and mobile technologies. In the technogenic educational environment, ICT can be the basis for interaction, co-editing and peer assessment in collaborative projects. In this case, students receive feedback not only from the teacher, but also from other students, which increases the motivation for independent learning. Thus, automated control, self-assessment and peer assessment can both identify problem areas for each student and design an individual learning path, which increases the effectiveness of learning a foreign language.

In automated control systems for technical processes, the conversion of a continuous signal into a digital code and vice versa from a digital code to a continuous (analog) value is widely used. For direct type converters often used the term ADC, the reverse - DAC. The characteristics of the converters often dramatically affect the parameters of the entire automated system. The importance of the correct choice of ADCs and DACs has especially increased recently in connection with the mass introduction of microcontrollers MC. Indeed, in addition to the ADC and DAC, it is necessary to place the processor core in the microcontroller's crystal, I/O interfaces and many other elements necessary for the functioning of the MC. The use of information converters in the construction industry imposes additional requirements on converters: for example, in building monitoring systems, precision ADCs with extremely high accuracy are often required (while performance may be low), in other applications it is necessary to provide the necessary parameters at a high level of industrial interference, etc. This article explores issues related to the rational choice of ADCs and DACs, taking into account current trends in the IT field and the specifics of work in the construction industry. Sigma-Delta converters are noted as the most promising models of direct type converters.
