Optimization of the production process in the sense of Industry 4.0
Sázavský, Jakub ; Březina, Michal (referee) ; Mauder, Tomáš (advisor)
Particularly the future of industry is and will be defined by the concept of Industry 4.0. Therefore, this thesis aims to describe the basic conceptions of Industry 4.0 in relation to the production process and demonstrate the possibilities of digital twin by using simplified model of a real production line. It explains terms such as the production process, the concept of Industry 4.0 and the queueing theory. The practical part includes a model of the section of a line in the printing company by the program Tecnomatix Plant Simulation, identification of bottlenecks, possibilities of optimization and evaluation of their impacts. Then there is an example from business practice and drawn conclusions.

Measurement of complicated shape parts using image processing
Sujová, Sára ; Březina, Michal (referee) ; Štětina, Josef (advisor)
The bachelor's thesis deals with the topic of wear measurement of the pinion gear of the REA actuator used in the regulation of the turbocharger wastegate system. The first theoretical part of the thesis describes the topics of wastegates, actuators, gears and optical methods. In the second part, a pinion measurement method is implemented using a digital microscope and an application to measure the width of the pinion tooth thickness designed in the MATLAB environment.

The use of a chassis dynamometer in automotive development
Obid, Daniel ; Březina, Michal (referee) ; Štětina, Josef (advisor)
This bachelor's thesis deals with the use of chassis dynamometers, which are an integral part of the development centers of the world's automobiles. The main goal was to create an overview of design solutions. Using information materials from AVL, the use of these dynamometers in automotive development was summarized. The used measuring cycles and their development after the "DieselGate affair" were presented.

Assessment of possibilities for reduction of water consumption in steel industry
Bohunský, Tomáš ; Březina, Michal (referee) ; Klimeš, Lubomír (advisor)
This bachelor thesis assesses possibilities for a reduction of water consumption in the steel industry and individual methods reducing water footprint in the whole process of steel making. At the beginning, the current situation of the steel industry is introduced and the problem with excessive water consumption classified. The biggest part of this thesis is then dedicated to the construction of universal procedure which can be applied in any steel plant. This procedure consists of analytical models and the specification of individual water-saving technologies. The results are compiled in a table containing the detailed influence on the whole manufacturing process.

Temperature sensors
Mudrák, Michal ; Březina, Michal (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with problem int the field of temperature sensors. The beginning of the work is devoted to the definitions of the basic terms which are closely related to this topic. It is followed by distribution, description of the principle and realization of touch sensors with an electrical output. Marginally are discussed suitability of use and comparison of individual sensors. Next, the principle of calibration of resistance and thermoelectric sensors is described. The most common sources of calibration errors and measurement offsets are also summarized. At last, there is a practical example of linear calibration of chosen temperature sensors.

The proposed solution MÚK D1 motorway with road I/23 and II/602 u Kývalka
Březina, Michal ; Sabadáš, Petr (referee) ; Kosňovský, Michal (advisor)
The master´s thesis focuses on modification of existing interchange Kývalka on D1 motorway. The purpose of this thesis is to design optimal solution of junction of roads I/23 and II/602 with D1 motorway connecting all directions, considering transport capacity a safety. The another part of the thesis is widening motorway D1 to six lane arrangement with one lane for slow vehicles. At first, several possible designs were suggested of which two were chosen for further elaboration as a search study. In the end, thesis contains the comparison of two chosen designs.

Hněvotín-Lutín Bypass - Location Study
Březina, Michal ; Matuszková, Radka (referee) ; Radimský, Michal (advisor)
The bachelor´s thesis focuses on a bypass of villages Hněvotín and Lutín which is designed as a relaying of existing road II/507 and which is solved due to increasing traffic intensity. Road is designed as a category S7,5/80 and leads south around the village Hněvotín. Further it crosses existing road II/507 and then continues north around the village Lutín. Furthermore, this work also deals with connection to the existing roads with level crossings. Terrain in this area is slightly wavy and there are mainly agricultural grounds. Designed route crosses existing transport infrastructure and water courses.
