Survey sketch execution in software in the Kokeš
Marek, Přemysl ; Matějík, Miroslav (referee) ; Berková, Alena (advisor)
The topic of this Bachelor's Thesis is to create three sample Survey sketches in the KOKEŠ program and to record video instructions for their creation. These instructions will further serve as a teaching aid in the subject of real estate cadastre. The first part of the Bachelor's Thesis deals with the KOKEŠ program, theory and history associated with Survey sketches. The second part discusses the practical process of creating a survey sketch from ordering it to handing it over to the client.

Measurement of mechanical quantities with the support of CCD cameras
Marek, Petr ; Richter, Miloslav (referee) ; Havlíková, Marie (advisor)
This master’s work deals with types of digital cameras used in industry. Furthermore, there are mentioned application areas of cameras in the automotive industry. There was created searches industrial cameras on the market. In the next part is described hardware interconnection of Basler acA 1300-60gc camera and measuring platform cDAQ 9178. Part of this work is to create a system for synchronization of camera and measured data. In the last part is developed program for image processing and determine the angle of rotation of the steering wheel.

Mathematical Model of motor vehicle driving gear
Marek, Petr ; Laurinec, Marián (referee) ; Porteš, Petr (advisor)
The subject of my master’s thesis is creating a mathematical model of motor vehicle driving gear using the software programs MATLAB / Simulink. The results are presented via graphs of the data gained from the simulation of a car driving on a determined track. The parameters used in the model come from a specific file and they can be changed anytime in order to correspond with the particular vehicle.

Wireless Control of Electronic Devices Using Mobile/Embedded Device Using WiFi
Marek, Petr ; Materna, Zdeněk (referee) ; Zemčík, Pavel (advisor)
The aim of this bachelor thesis was to design and implement an automated home system using Wi-Fi. The whole system was built on the Raspberry Pi and ESP8266 platforms, CoAP was chosen as the communication protocol. The resulting solution works in the local network and also over the Internet. It includes the use of several types of sensors and the ability to control the outputs of the ESP8266 modules. The system supports simple automation based on values of sensors and set timers.

The Death Pit and the Glowing Swamp: A Permeation
Smutný, Jan ; Marek, Petr (referee) ; Cenek, Filip (advisor)
The work is connecting well-known symbols of alchemy and various esoteric traditions and giving them visual and narrative form. There is deconstruction and glorification of this type of philosophy in the same time. The characters of the story are symbolizing the german and slavic archetypes. Their voyage from the pit of death to the glowing swamp and vice versa is representing the ageless story of life and death, creation and destruction, body and soul, light and darkness. All the symbols are used in the ironic and serious way in the same time.

Realization of differential power analysis
Marek, Pavel ; Dzurenda, Petr (referee) ; Martinásek, Zdeněk (advisor)
Nowadays, it is not enough to pay attention to encryption algorithm security from the mathematical aspect only. It is also necessary to pay attention to the implementation of encryption algorithm, because encryption devices can show plenty of information about implemented encryption via undesirable communication. This bachelor thesis deals with side channels issues (especially power side channel) and their use to obtain the secret key of AES encryption algorithm. For this purpose there are three operations realized in this thesis. At first, there is experimental workplace designed, which provides automatic saving of waveforms of encryption. Then there is a simple and differential power analysis of these waveforms performed. All parts are theoretically described in individual chapters. After theoretical description there is the practical part, which describes a proper realization of all tasks.

Crank mechanism of in-line four-cylinder spark ignition engine
Marek, Petr ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective of this bachelor’s thesis is for given geometric, thermodynamic and operation parameters cylindrical unit of in-line four-cylinder spark ignition engine perform calculation of thermodynamic cycle, project basic proportion of piston group and for given operation modes perform strength check of connecting-rod eye. In the introduction is described ordinary use of spark ignition engines, several details of history of their evolution and present most widly used construction. Major text of bachelor’s thesis attend to four main chapters: description of thermodynamic cycle, calculation of forces reacting to piston, strength calculation and check of piston pin and of connecting-rod eye. Supplement consists of accomplishment of these calculations and a few of graphs. In the conclusion is evaluation of performed calculations and there are mentioned technological directions of present evolution of gas-engine.

Effect of pH on quantitative determination of additives in nanofibers
Grufíková, Jana ; Marek, Pokorný (referee) ; Knotková,, Kateřina (advisor)
The object of my thesis was to prepare a nanofiber layer with dye additives and to quantify the additive content in dependence on pH. The nanofiber layers with additives were prepared by means of electrospinning. The analysis of the additive content in samples was performed by UV-VIS spectrophotometry. Concretely Erythrosine, Eriochrome Black, Riboflavin and Brilliant Blue were analysed. Each of this colors has different chemical structure and charge. The pH was defined by use of buffers, namely acetate buffer (pH 5), phosphate buffer (pH 7,4) and carbonate buffer (pH 10). For Erythrosine and Eriochrome Black the research was extended to study the effect of ionic strength on the quantitative determination of these dyes. It was found that the quantity of the determined additive depends on the pH and also on the ionic strength. However, this dependency is different for each additive. This confirms the assumption of influenced chemical structure and charge by interaction with polymers and buffers used in this experiment. The accuracy of evaluation is influenced by the way of data processing.

Implementation of Smart Factory
Marek, Pavel ; Krajsa, Ondřej (referee) ; Škorpil, Vladislav (advisor)
This diploma thesis is focused on the study of concept of Internet of Things, concept of Industry 4.0 and on current conditions in smart factories. Based on these studies there was designed and implemented hardware and software adjustment for industrial machines and connection of these industrial machines to communication network. There was designed and programmed the application in the C# language. This application provides a data collection from industrial machines, provides various services for machines and humans and this application is processing and viewing necessary data. For these purposes the application is using a database system based on the SQLite. These tasks of designing and implementation are summarized to system, which is determined for smart factory implementation. This implementation is created according to Industry 4.0 concept.
