Analysis and risk assessment of construction technologies of structures in an integrated management system
Komárková, Jana ; Bednářová, Bronislava (referee) ; Vymazal, Tomáš (advisor)
This thesis deals with the analysis and evaluation of quality, environmental and safety risks and the application of appropriate methodologies to concrete construction work. For application are selected key construction technologies, which are classified according to the Classification of building structures and works (TSKP) in Chapter main building production (HSV). From ČSN EN 31010 Risk management – Risk assessment techniques were selected for work tools - Causes and effect analysis, Failure Modes and Effects Analysis (FMEA), Pareto diagram, Bow tie analysis. The aim of this thesis is to analyze and assess the quality, environmental and safety risks of selected construction technologies and conditions established an integrated management system to handle simple tools for the management andelimination.

Finishing milling of accurate surface
Šimonek, Ondřej ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The aim of this work is to find a suitable cutting tool and suitable cutting conditions for the production of hydrostatic surfaces of a crossmember with the quality of the surface structure of Ra 0.8 mm. The technology described in the thesis deals with finishing hydrostatic surfaces by milling, with the quality of the surface structure of Ra 0.8mm. As the production method cutting operations using CNC machines is used. To assure the quality of the surface insert tools are used, which are selected and evaluated based on experimental testing from six different suppliers. The technological process of production solves the problem of the hydrostatic surface production from the first gripping all the way to the final manufacture of the surfaces.

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.
