International Conference on Industrial Engineering, Applications and Manufacturing took place on May 16-19, 2017 in Saint-Petersburg, Russian Federation. The conference was organized by the Russia Siberia Section Joint PES/IES/IAS/CSS Chapter supported by the South Ural State University (national research university), the Peter the Great Saint-Petersburg Polytechnic University, the Platov South-Russian...
The widest application of the Radon transform and its various modifications is digital image processing. The article deals with the experimental algorithm of steganographic embedding and extraction of hidden messages using tomographic methods. In the course of the research, an analysis was made of known methods of steganographic embedding and extraction of hidden messages. It is necessary to investigate...
The results of dimensional parameters mathematical modeling for a drum set, providing the necessary degree of heat treatment, are presented in the article on the basis of the developed mathematical model of the process of thermal modification for a cellulose filler for wood-plastic composites. The studies show that the drum diameter provides more than twice the greater impact on the process efficiency...
The method is suggested to establish master-slave communication between the Siemens PLC and field devices based on the Modbus protocol for process control systems. The data exchange between the PLC and current node in the network is organized by using the session data blocks. Creating the request package and unpacking the response from the slave device are carried out by the two respective functions...
The paper is devoted to development of design and control algorithms, analysis of dynamic properties and control of the drive with a series-wound motor. It is aimed at specifying optimum ones in terms of energy losses as well as verification of the solutions obtained. When analyzing electromagnetic processes and functional control design, the principles of dynamic programming and spectral method of...
The results of the heat supply system work modeling are presented. The electronic model of the considered system is created.

This article studies the structure of a bandpass filter. The suggested filter consists of two identical meander transmission lines short-circuited at both ends and two feed lines located at the opposite side of the substrate responsible for the filter input and output. The device was designed with the use of the material with the dielectric conductivity ε=4.4 and the thickness h=1.5 mm. Lines in the...
More than half of the oil wells fund in the Russian Federation is operated with the help of electric submersible pumps providing up to 75% of all oil produced in the country. However, electric submersible pumps have a rather high specific energy consumption in the extraction borehole fluid. The greatest difficulty is the definition of losses in the submersible motor cable. The author has received...
If in a confined space of the wedge type the marine environment is heterogeneous, any calculations by developed mathematical methods would be highly problematic. The proposed mathematical algorithm is used for separation of variables under combined boundary conditions. The obtained calculated formulae are based on the Green's functions that have angular dependence. This angular dependence allows determination...
The arc column mathematical model taking into account the thermodynamic processes in the damaged equipment is described in the article. The functioning of the model is based on the use of the first law of thermodynamics and the 2nd Kirchhoff's rule. Nonlinear dependencies of the electrical and thermodynamic parameters on temperature and pressure of the arc column plasma play an important role in the...

Operation analysis and synthesis of the coordinated rotation system based on the two-speed induction motors (IM) with cage rotors presented. The circuit uses a transistor voltage controller to maintain the speed of IM. The second group of IM windings is used for parametrical synchronization, while transistor controller is used to compensate for the residual error. Transfer functions of the original...
The main parameter for the operational control mode of devices with surface dielectric barrier discharge (SDBD) is the voltage on the dynamic plasma load. In this case, to obtain most efficient mode, the power supply is set up with plasma load into resonance (by adjusting the supply voltage frequency).
