The article presents the prerequisites for the relevance of the processing and disposal of galvanic sludge generated from industrial enterprises, which in turn occupies numerous areas of land for storage, which harms the environment. An overview of the methods of processing and disposal of electroplating waste, including physical, chemical and biological processes. Experimental studies of galvanic sludge sediment are presented. The precipitate is a mixture of crystalline CaCO3, SiO2 and an amorphous phase, which is not determined by phase analysis. Modern advanced technologies for the processing and disposal of galvanic sludge are presented.

The article presents the results of a study of the stepper motor control system of a road printer. The use of a stepper motor imposes additional requirements on the road printer in terms of operating parameters control. The main requirement for the stepper motor of the road printer is to ensure the rotation of the rotor, at a given angle, which depends on the control mode. The description of the road printer is given. The dependencies of the stepper motor as a control object are given. Investigated for the stability of the Nyquist system. A simulation model of the stepper motor control system of a road printer has been developed and simulation results are presented.

A new parallel programming language is being developed. A feature of this language will be that, based on the developed algorithm for solving any problem, it is possible with minimal effort to generate an effective parallel program code for different computation models. Such a parallel metalanguage is based on the dataflow computing model with a dynamically formed context. The graphic version of the metalanguage has the advantage of a clear presentation of information and is much better suited to the nature of human perception. The concept of graphical programming consists in compiling a program from a set of certain objects and connecting them together according to special rules. In addition, each of the objects and the connection between them in the form of a directional line have a set of properties and attributes, which, when compiled, convert them into an object with the necessary logical load corresponding to the program algorithm being created. The article provides a graphical representation and description of such metalanguage elements as “token”, “standard node” and “single-port node”, “node with three standard inputs” and “group symmetric node”, as well as program structures: “group”, “cycle” and ""module"". A whole series of parallel programs was created using a graphical version of the metalanguage.

There are various programming models for high-performance computing systems. Each of them has its own requirements for the structure and properties of the algorithm, which force the rewriting of the algorithm to match them. One solution to this problem is to move to a new parallel programming paradigm. The new metalanguage of parallel programming will give the opportunity to create a mathematical description of the algorithm, and then derive from it effective programs for various computing platforms. The article describes the approaches to the translation of the program into its own basic subset of the parallel language of the parallel dataflow computing system (PDCS). The basic concepts of the metalanguage are defined. The limitations of the basic subset of the PDCS parallel language are given. It describes the options for translating multi-input nodes and program structures (groups, cycles and branches). Translation of the program on the metalanguage into the basic subset of the PDCS parallel language will further help to solve the problem of translating the metalanguage into languages of other architectural platforms.
