In this master's thesis an automatic ultrasonic control system for pipes using LRUT technology was developed. This topic is relevant today as automation and large volumes of non-destructive testing require systems that can handle this. The system proposed in this paper consists of modern technologies in UZK. To ensure acoustic constant contact between the object of control and the system, the latest ideas are used. The simulation of the system was carried out using modern software. Also, development of a potential startup of the project was conducted, and the possibility of the system's exit to the international and domestic markets was considered.

The purpose of the master's thesis is to explore the possibility of using ultrasonic control of large diameter and size pipes.
The developed system can be applied to non-destructive control as a primary or auxiliary. Also, due to the versatility of the algorithms, work with minimal changes can be rebuilt for another way of finding defects in the pipelines.

In the master's dissertation the review of literary sources on the subject of diagnostics of a person's view was conducted. Defects and visual impairments, as well as the possibility of their detection, are described. The main focus on the review was the violation of the perception of color by the human eye and the existence of systems by which such violations can be detected. On the basis of the review of literary sources, a functional scheme was developed and a selection of elements was made that allow automating the diagnostic process of the system. Synthesis of the system with the use of software, in coordination with elements of the functional scheme is executed. Also in the dissertation there is a section of the development of the startup project, which describes the possibility of the release of this system on the market and to compete with existing analogous systems.

In the master's thesis the instruments, axle control systems, their comparison, and the choice of the method of the method of analysis were analyzed.
The characteristics of the automated non-destructive testing system, advantages and disadvantages are considered. An ultrasonic wheel axle control system was developed. A system is proposed that includes a mechanical block, a flaw detection unit, and a data processing unit. The defectoscopy unit consists of four channels of two transducers in each. The marketing component of the startup project is analyzed to determine the possibility of its implementation and possible market directions of implementation.

In this master's thesis was developed Bluetooth indoor orientation system.

This topic is relevant today, since in the conditions of automation of production processes the same tendency occurs in non-destructive control, and for automatic or automated devices of non-destructive control, orientation systems in space are required.

System, proposed in this work, consists of modern software and hardware components. The hardware part is Bluetooth-beacons, based on the newest Bluetooth LE v4.0 devices, and any device equipped with a Bluetooth module can be a signal receiver. The software part performs the functions of measuring the distance to control points (beacons), calculating the coordinates of the object location, and filtering the data.

In the master’s thesis was carried out research of possibilities of creating a method of non-destructive testing using parameters of eddy current’s higher odd harmonics up to ninths.

Possible methods of signal analysis were investigated. The orthogonal method of analysis is proposed as primary algorithm. The mathematical model was created and used to investigate dependencies of measurement accuracy from signal parameters. After getting practical data, methods of statistical analysis were used to determine the type of used process.

The study found that orthogonal method of signal analysis demands particular characteristics from signal’s structure, which makes system’s plan more complicated. Statistical analysis shows that process of measurement has assignable cause, but it is not severe and methods of dealing with it were proposed.
