In this work, an ultrasonic monitor for composite materials products was designed.

At the first distribution, there is a complete analysis of the types of composite materials with ultrasound control, the physical and mechanical characteristics of composite materials are examined, and the brown-and-white method of ultrasonic monitoring is wound up. In the second section, the acoustic path of the device was calculated and the geometric dimensions of the piezoelectric plate were determined.

In this work, an eddy current flaw detector was designed to determine the operational damageability of structural elements. The introduction substantiates the relevance and necessity of development.

In the first section, an analytical review was conducted, which considered: the main parts of the aircraft glider, in particular, their skin and the material from which it is made. Defects that appear in the casing during operation have also been reported. In addition, a general review and regulatory framework for eddy current control and available devices on the project topic were conducted.

The aim of this bachelor's project was to develop a portable mobile flaw detector that can be easily adapted to new controls and different classes of tasks.

The first section presents an analytical review, which describes: ultrasonic vibrations, methods of ultrasonic flaw detection, provides theoretical information about ultrasonic transducers. In the second section, which is also computational-theoretical, the piezoelectric transducer that best performs the tasks was selected and calculated.

The diploma project of the fourth-year student, group PK-61 of the Faculty of Instrument-Making Anna Yakymchuk on the topic: "Ultrasound device for measuring of blood flow velocity in blood vessels." The diploma project consists of 60 pages, 27 drawings, 16 literary sources.

Key words: ultrasound, dopplerography, piezoelectric sensor, blood velocity in vessels.

The diploma project is devoted to development of ultrasound device that is designed for measure the speed of blood flow in blood vessels. In the first section, the existing methods of ultrasound non-destructive testing were analyzed and based on this information, the method on which the work of device will be based was determined.

This bachelor’s degree project is concerned with the development of the automated device for smoke detection in living areas and the estimation of smoke concentration. Existing technologies were combined into one automated system and the research on the Mie scattering was conducted in the diploma project.
The purpose of the project is to develop and calculate the parameters of the automated device for smoke detection, draw the electric circuit diagram, draw the functional diagram, and describe the principle of the circuit operation process.

The author explains that infrared and blue radiation detectors were selected for the project taking into account the relative spectral characteristics of the emitters.  It was noted that the optical scheme was developed and the Mie scattering was designed in the Zemax program, as well as the electrical path for operating with the infrared radiation detector and current source. Then the author provides the information on the calculations of the electric path and the calculation of the average particle diameter according to the Mie theory of scattering.
