The Use of Additive Technology for Manufacturing Components of the Sample
Vrbická, Eliška ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
Thesis deals with the use of additive manufacturing technologies for the production of sample components. These are mainly using method Fused Deposition Modeling (FDM). The production was used to 3D printer for based on this principle. Manufactured subject has own design of pendant, this pendant has shape of blooming flower with leaf. The model was created in SolidWokrs 2013. This model is further elaborated in the program CatalystEX. Thus originated data for the printer Dimension uPrint. Once printing is complete and upon dissolution the of aid were removed imperfections printing. Thus-to-terminated object can be used as a garnish.

Usage of Busbar as a Source of Heat
Svoboda, Ondřej ; Macháček, Jan (referee) ; Radil, Lukáš (advisor)
This study is dedicated to the use of heat energy from the busbar and its cooling system. The study deals with thermal analysis of the busbar, both using numerical simulations in SolidWorks and practical examination – warming of the busbar. We can verify the correctness of the simulation from the measured values. To determine the temperature profile of the busbar, it is necessary to measure the temperature at various points of the busbar by contact method using thermocouple or contactless method using a thermal imager. Measurements are performed at the busbar LIA1600 made by Siemens Busbar Trunking System Mohelnice. The aim of the study is to analyze temperature busbar, to suggest the most efficient method of heat recovery, and to make economic calculation

Design of up-to-date laundry premise model
Marek, Tomáš ; Máša, Vítězslav (referee) ; Pavlas, Martin (advisor)
Scope of this thesis is the design and evaluation of a laundry processing facility. Main goal was to prepare, design and evaluate part of the technological layout for a modern, high-volume laundry processing facility. The focus was on the main apparatuses, main process flow, as well as the supporting process flow, related equipment and key components of field instrumentation with standard description. 3D facility model was prepared on the basis of proposed technological layout, using the SolidWorks software package. This model shows placement of all key equipment and components as well as physical disposition of connection tubing within the building. Final part of work reviews proposed options of process parameters measurement. Such measurements which are important for the evaluation of energy consumption of considered laundry processing. We discuss both pros and cons of evaluated and selected suitable measurement devices, tools and procedures. Constructed 3D model of piping lines shows placing and dimensions of selected measurement devices.

Home gate for IoT devices using Z-Wave technology
Resler, Tomáš ; Krajsa, Ondřej (referee) ; Hošek, Jiří (advisor)
This dissertation deals with the platform Z-Wave. This platform tries to create an universal system for smart home. The theoretical part of the work describes in details the platform itself as well as the applicable libraries for programming of applications and the available equipments. The practical part presents the new custom gateway. The hardware of this gateway is designed with utilization of the Z-Wave module, Raspberry Pi 3 microcomputer, touchscreen, powerbank and the body of the system. The body has been designed in the Solid Works CAD system and printed on a 3D printer. The needed firmware was loaded into the Z-Wave module ZM5304 and this module has been interconnected with the Raspberry Pi 3 through the printed circuit board of the custom design. The gateway drives OpenZWave network through the new own application written with help of Python wrapper of the library OpenZWave and other open source components. The part of the work is also the list and description of the alternative commercial gateways available on the Czech market.

Design of electromagnetic laboratory shaker
Vaněček, Michal ; Březina, Lukáš (referee) ; Hadaš, Zdeněk (advisor)
My thesis describes the design of a laboratory electromagnetic vibrator, which will be used for testing of the vibrating microgenerators. In the first part of my thesis is the search of selected laboratory electromagnetic vibration generators. There is also formulated its own proposal and subsequent tuning of the required dimensions and characteristics of the laboratory electromagnetic vibration generator. The tuning of necessary properties and dimensions is formed as modeling and simulating in programms Matlab / Simulink and ANSYS. The conduct of laboratory electromagnetic vibration generator is implemented in MATLAB / Simulink. Design and dimensions of the laboratory electromagnetic vibration generator is made in SolidWorks.

Analysis of pressure distribution in the variant detector with three aperture by CAE system
Tomášek, Martin ; Vyroubal, Petr (referee) ; Maxa, Jiří (advisor)
This master`s thesis analyzes the pressure distribution on the premises of scintillation detector secondary electron in the variant with three aperture. The aim of this study is analyzing the fluid flow depending on the application of the third aperture in the entrance of the detector, thus creating more self-pumped chamber, which is responsible for ensuring a better distribution of pressure in the premises of the detector. The result of the analysis would be determining how to change parameters within the detector. If it is found that application of the third aperture has a positive effect on water flow in the premises of the detector, this arrangement may be used for improvement of the detector. Master`s thesis is divided into several chapters. First describes the basic principles of electron microscopy, including sample preparation, conditions for the proper functioning of microscopes and sharing different types of electron microscopes. The next chapters describe briefly the physical descriptions of gases flow in low pressures and small apertures, the mathematical models and simulation software used in this analysis. The analysis is done in SolidWorks with the module called Cosmos FloSimulation. The conclusion summarizes the results of the analysis, including graphical representations of simulation.
