Technological parameters of abrasive process
Řehák, Pavel ; Bumbálek, Bohumil (referee) ; Prokop, Jaroslav (advisor)
In this work, there is described an abrasive process including technological terms with an identification of motions and a speed of grinding.Then there are described abrasive tools, their distribution and description. In the last part there are introduced some reached parameters of the accuracy and characteristics of the surface structure in dependence on the length of abrasive process.

Machine grinding
Beseda, Vojtěch ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
At the beginning of this dissertation an overview of grinding technologies is presented. The following chapter presents a selection of grinding machines from databases and manufacturers’ catalogues. At the end, a case study of grinding processes in a small manufacturing company is analysed. It focused on the action of grinding an internal cylindrical area on thin wall housing. The solution is the adaptation of component´s attachment, the adjustment of the working cycle and the dimensional control according to drawings.

The manufacturing of electromotor covering
Stejskal, Luboš ; Špaček, Jindřich (referee) ; Podaný, Kamil (advisor)
This project has been presented for the bachalor branch of study, B2307, it shows the proposal of technological and production process for deep drawn parts. They are produced from the steel (11305). Due to the production volume of 100.000 pieces per year, it was proposed to implement the production process. It basis of the literature study which describes the potential pitfalls of deep drawn technology. After control a technological calculations it was decide to choose the stamping machine CTC 250 (manufactured by ŽĎAS, a.s.).The deep drawn tool has been designed in order to use the maximum capabilities of this stamping machine, specially the upper ejector and the lower holding device.

MCUXpresso Web application security
Mittaš, Tomáš ; Heriban, Pavel (referee) ; Roupec, Jan (advisor)
This thesis deals with testing of the security of web application MCUXpresso Web SDK Builder using ethical hacking techniques and tools. At the beginning, the history of ethical hacking and structure of web applications are briefly mentioned. The thesis then analyses the application itself from the user’s point of view, its parts before logging in and after logging in and the operation of this application. The following is a list of the most common vulnerabilities and weaknesses found in web applications to understand any vulnerabilities found. Furthemore, the thesis deals with the techniques and tools of web application security and compares them. The penultimate chapter deals with the use of Analysis and vulnerability scanning technique on the application MCUXpresso Web SDK Builder. Finally, an application security test plan is designed, while part of this plan is automated.

Superhard cutting materials and their effective use
Teplý, Radek ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
Diploma thesis is focused on the superhard cutting materials (polycrystalline diamond, polycrystalline boron nitride) and presents their physico-mechanical properties, production, efficient use, new trends. It assesses the range of cutting tool materials and individual front world producers in terms of optimum cutting conditions for turning operations and type of material to be machined. Further, these cutting materials are compared between different manufacturers to bring out thein differences in cutting conditions.

Experimental Hardware Musical Instrument
Chaňo, Petr ; Vrba, Kamil (referee) ; Dlouhý, Dan (advisor)
The main aim of the bachelor thesis was to design and build a musical instrument that will have a signs of the experimentalism consist of combination synthesizer and sequencer, tuning, unusual kind of controls and its look. At the top of this work is the theoretical introduction to the musical instruments and to the process of generating and modulating sound. There is also written information about parts that the instrument consists of (microcontroller, D/A converter), principles that leads to being able to create this instrument (operational amplifiers, frequency filters, DDS) in the theoretical part. The description of the components is in the practical part followed by the information about the circuits at this instrument and about software solution as well.
