Design of the X-ray system cabinet
Slávik, Andrej ; Pavlík, Jan (referee) ; Huzlík, Rostislav (advisor)
This diploma thesis deals with the design of an automated interface of sample exchange, as an extension for the existing concept of an industrial CT cabinet. The solution is intended for laboratory conditions. The design is based on the idea of a conveyor system that transports samples from a tray to the CT cabinet, where they are accurately placed on a rotating stage and prepared for CT analysis. Once the analysis is complete, the sample is returned to the tray. One of the main requirements of the solution is the continuous operation of the X-ray source, which is solved by adding a chamber to the conveyor system before the sample enters the cabinet. The design has been developed taking into account the legislative safety requirements. The work also includes a preliminary design of the workplace control and also technical drawings of the assembly.

Indication apparatus installation for a diesel engine
Slávik, Andrej ; Ramík, Pavel (referee) ; Beran, Martin (advisor)
The issue of measuring combustion pressure has been a part of internal combustion engines since their inception. The measurement evaluates the course of pressure as a function of volume change. This dependence is plotted in indicator diagrams. Other parameters are evaluated directly, such as combustion noise, but also indirectly, i.e. by calculation from the values of indicator diagrams. Measurements can be performed with different types of sensors. However, these sensors must be properly positioned to measure the correct values. For a given motor with a problematic sensor location, a suitable sensor is selected using calculations. The engine cylinder head is processed by reverse engineering methods. According to the acquired knowledge and available solutions, two variants of piezoelectric sensor placement are proposed with the recommended use of variant no.1.
