Borsuk, Adam ; Kolařík, Martin (referee) ; Číka, Petr (advisor)
The aim of the bachelor thesis is to study the design and creation of an automatic hydroponic system for plant cultivation and to solve the creation of components of the system according to the basic conditions for plant growth and subsequently to test and verify their properties, to evaluate their functionality. The second goal is to create a communication interface for sending and storing data from the system while creating a transparent display of stored and up-to-date data. The third objective is to verify the functionality and stability of the selected microcontroller as a control unit.

Test Rig Design Proposal for the Experimental Validation of Transmission Parameters in Closed Loop Torque Condition
Otipka, Václav ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The thesis deals with the design of the experimental testing rig. Test rig is designed to measure NVH transmission parameters. First, basic knowledge of vibro-acoustic measurement is discussed. This is followed by an evaluation of the most commonly used power devices to derive real loads on measured gearboxes. In more detail, a back-to-back test rig is disassembled among other things. In the thesis are described two main components, which are composed of a connecting element and a test bench. Both components were optimized during the design due to their modal properties. Numerical modal analysis was performed in ANSYS Workbench software. The thesis also includes strength calculations performed using both numerical and analytical approaches. The indispensable result of the design work is the complete drawing documentation. Finally, measurements of vibrations and noise on the physically made connecting element assembly have been performed and subsequently evaluated.

Jaroš, Zdeněk ; Janík, Daniel (referee) ; Mastný, Petr (advisor)
The aim of this work is to get acquainted with problems connected with a designing of power and data distribution, a definition of principles necessary for a drawing design and a project realization of an electrical installation for a detached house. The first part of the thesis deals with the definitions and principles related to safety and security administration, which must be respected at designing the project documentation. In the following part of this thesis there are presented the conditions and selected methods of connecting the object to the low voltage distribution network, methods of conducting heavy and low current rake and the lighting design. The second part deals with the designing of a specific electrical installation project for a detached house. The content presents the heavy and low current installation in a ground plan of the house, a switchboard design, a lightning conductor, and a technical documentation in accordance with actual technical standards. The technical report also includes economical evaluation of the project.

A Laboratory Task: Oscilloscope Measurement
Malý, Ondřej ; Steinbauer, Miloslav (referee) ; Marcoň, Petr (advisor)
Bachelor thesis deals with the design of a signal generator for a laboratory task of the subject HELE. As a generating chip is used ICL 8038 that can generate three types of waveform – sinus, square wave and triangle. The frequency range is from 20 Hz to 20 kHz in selected circuit. Output is connected to oscilloscope probe, but also to 3.5mm headphone jack through which can be the selected waveform listened to on the connected headphones or speakers and measure the audible threshold.

Design of Line-start synchronous machine
Lolová, Iveta ; Klíma, Jiří (referee) ; Bárta, Jan (advisor)
This thesis deals with line-start permanent magnet synchronous motor, because in these days the world focuses on energy saving more than ever. Line-start permanent magnet motors represents a possible replacement for asynchronous motors, which are the most used kind of motors and constitute one of the greatest energy consumption apparatuses in the world. The efficiency improvement of induction motors is usually achieved through design optimization of induction motors resulting in limited degrees of success. This thesis also thoroughly explains LSPMSM topology and compares properties of the line-start permanent magnet motors and asynchronous motors. This thesis deals with the design of line-start permanent magnet synchronous motor based on previously designed asynchronous motor. In the last chapter LSPMSM is investigated in RMxprt and Ansys Maxwell.

Formula Student Anti Roll Bar System Design
Urban, Marek ; Janoušek, Michal (referee) ; Ramík, Pavel (advisor)
This bachelor’s thesis is focused on design of rear anti roll bar system of single-seated Formula student car. It is a concept with torsional bar and third damper used for example in Formula 1. Design is partially inspired by topology optimization. The emphasis is on optimization using finite element method to achieve desired stiffness at low weight. Optimization is done in series of static analysis iterations of individual parts and of the whole system in several driving states. Design of front anti roll bar system with adjustable blades is made along with front third rocker system.

Design of RC sinusoidal oscillator based on active building blocks
Režňák, Patrik ; Šotner, Roman (referee) ; Kartci, Aslihan (advisor)
Bakalárska práca je venovaná RC oscilátorom s použitím funkčných blokov a operačných zosilovačov. Na počiatku je urobený rešerš literatúry zaoberajúcej sa konštrukciou a návrhom RC oscilátorov, a použitiu rôznych funkčných blokov pri tomto návrhu. Jednotlivé funkčné bloky sú diskutované a sú vybrané rôzne zapojenia s použitím týchto blokov, ktoré sú simulované analýzou na počítači pomocou PSpice a SNAP. Je overený vznik oscilácií a vplyv jednotlivých súčiastok v zapojení. V druhej časti sú realizované vybrané zapojenia a overené teoretické poznatky na praktickej realizácii. Údaje získané z počítačovej simulácie a praktickej realizácie sú potom porovnané, a taktiež jednotlivé zapojenia sú porovnané medzi sebou.

Efficiency improvement of single-phase induction motor
Bořil, Michal ; Mach, Martin (referee) ; Vítek, Ondřej (advisor)
The subject-matter of the Bachelor Thesis is increasing efficiency of a single-phase asynchronous motor. The thesis is divided into several parts and comprises information concerning the subject-matter. The first part deals with the theoretical principle of all rotary machines from three-phase motors to single-phase motors, describing the principle, design and functionality of these devices in detail. In the second part, a new motor model is designed on the basis of the label values of a specified asynchronous motor and adapted to have the highest possible efficiency. The model of the motor is created in the ANSYS RMxprt program and compared to a model of the specified motor, which is also created on the basis of parameters of the technical documentation in the same program. In the last but one part of the Bachelor Theses, several models are created with proposed modifications of the motor to increase efficiency and compared to the specified motor. This part focuses on an analysis of individual types of losses that influence the efficiency and power of the motor. In the last part of the Bachelor Thesis, in the ANSYS Maxwell program, a model of the specified motor and a model of the motor with the highest efficiency is simulated with the use of FEMM. The obtained information of the models from the Maxwell program is compared to information obtained from the RMxprt program and evaluated.
