Process control of a distillery
Sejkora, Martin ; Kopečný, Lukáš (referee) ; Veselý, Libor (advisor)
This master‘s thesis deals with the design of a control system for a distillation column. It deals with the issue of distillate production and acquaints the reader with the necessary knowledge that is necessary to understand the purpose of the work. The practical part of the work presents a specific distillation column, the means for its control and the method of implementation of the control system, then the visualization of the control system and the method of control. Part of the work is the evaluation of the results and benefits of the work.

Calculation of thermal resistance of finned heatsink
Kyanka, Radim ; Huták, Petr (referee) ; Toman, Marek (advisor)
This bachelor's thesis is focused on the problem with analytical calculations needed to define thermal resistance of finned heat sinks. First it describes how temperature proceeds at different boundary conditions at fin tip. Than it describes different mechanisms of heat transfer, equlation of heat resistance especially of natural and forced convection. To verify the results there is comparison between analytical equlations written in Matlab program and measuring results.

Design Solutions and Development Trends of Formula Student Cars
Adámek, Ladislav ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
This bachelor´s thesis is engaged in history and description of progress and recent trends in Formula Student/SAE competition. The bigger part of this thesis is devoted to complex summary of structural designes of monoposts and construction units of most succesfull teams. The point of this survey was getting information about construction of competitor´s cars. Theese informations should be used for building own car.

Design of testing rig for static and cyclic stress by pressure
Gerák, Jakub ; Polášek, Přemysl (referee) ; Škopán, Miroslav (advisor)
This diploma thesis describes the design of equipment for static and cyclic loading of coolers by pressure. The aim is to first identify the necessary parameters from the tested coolers. Then, based on the obtained data, design the hydraulic circuit, including the parameters of individual components and motors, followed by the design the control logic, which is required for designing the control system.

Optimization of air conditioning of the wellness sports center
Prchalová, Nikol ; Rubina, Aleš (referee) ; Blasinski, Petr (advisor)
The diploma thesis deals with microclimate of a pool hall. This is divided into three parts. The first part describes the theoretical aspects of the environment in swimming pools in general. The second part of the diploma thesis deals with the calculation of the course of specific moisture concentration during the day in the pool hall. Different humidity concentration curves are assessed based on different electable input parameters. Subsequently, suitable setting options are evaluated in order to achieve acceptable environment in the hall in terms of humidity and optimal operating costs. The last part relates to the experimental part. This examines the measurement of evaporation under different boundary conditions and the subsequent comparison with some calculation methods for the calculation of evaporation.

Heat transfer in modern automotive lights
Holec, Radek ; Klimeš, Lubomír (referee) ; Štětina, Josef (advisor)
The beginning of this thesis is dedicated to light in general and all different types of vehicle lightning, also deals with various types of light sources and specifically about LED where it describes the temperature change behaviour. Second part deals with heat transfer by conduction, convection, and radiation, it describes quantities and relationships needed for next capitols. In the penultimate part is described thermal management of headlights, therefore different options of cooling and causes of heat generation, and different types of PCBs that are used in automotive. In the last part is proposed the heatsink, which should be used for cooling LED chips of daytime running lights.

Hydrostatic drive of multi-purpose loader DAPPER
Vydra, Tomáš ; Merenda, Lukáš (referee) ; Škopán, Miroslav (advisor)
This thesis deals with design of hydrostatic drive for multipurpose loader and tool carrier DAPPER. At the beginning is research of different basic concepts and modern solutions to the problem, aided by a detailed description of competitive machine in the same performance category. Extensive comparison with other producers is included in the annexes to this thesis. Furthermore, a theoretical driving characteristic and its appropriateness is examined further on the basis of two model situations. The calculations of the individual components of the hydraulic circuit precedes drive kinematics analysis of articulated machine frame, on it final conception of hydrostatic drive is chosen. Firstly hydromotors and hydogenerator are chosen on the grounds of calculations then hydraulic hoses, filters and flow divider. Next chapters are aimed to calculations of hydraulic losses and thermal calculation of hydraulic circuit. Final part deals with introduction the final characteristics of drive. The practical parts of the work are assembly drawings with main power components and hydraulic schematic of drive.

Modification of Aluminium Cooler Holder
Malovaný, Daniel ; Ramík, Pavel (referee) ; Svída, David (advisor)
The purpose of this thesis is to overview the basic design solutions of full aluminum radiators. By finite element method to check the first generation of full aluminum low temperature radiator bracket and based on this calculation to modify the design to reduce tension in the critical areas. At the end of this thesis to evaluate the new design.
