Vehicle Hydropneumatic Unit
Koudelka, Roman ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis, following the bachelor's thesis, is devoted to the gas-liquid unit of a vehicle, as the central element of hydropneumatic suspension. The aim is to dimension and construct this component and integrate it together with other elements into a complex suspension system. Based on possible forms listed in the research section, regarding to current development trends, the form of the unit is chosen. The practical part begins with simulations comparing a hydropneumatic with a conventional suspension system. After solving this issue, it is possible to proceed to the dimensioning of the basic parameters of the unit and then to its construction, respecting the relevant strength calculations. The last step is to build a conceptual design of the whole hydropneumatic suspension system.

Lighthouse for maritime communication
Chadima, Jan ; Mašek, Pavel (referee) ; Pospíšil, Jan (advisor)
This bachelor thesis deals with design and construction of lighthouse model, which will be used for teachning. It describes types of naval signalizacion, which are established by organization IALE in decree E-110. In thesis is described Arduino platform, metods of 3D printing and used materials For model needs was designed printed circuit board with microcontroller ATmega328P, which control RGB LED. Program, which control model, was writed on Arduino platform. Program has nine modes of sea light comunication. It can change periode, color of LED, brightness and turning on power saving mode. The result of this work is a functional model of lighthouse powerd by battery. Model is based on Green Cape Lighthouse in Australia in scale 1:58.

Design of a photovoltaic power plant for a family house near Jihlava
Dvořák, Vít ; Maule, Petr (referee) ; Vaněk, Jiří (advisor)
This diploma thesis deals with the design of a photovoltaic solar power station for a specific family house in the Jihlava region. The aim of the work was to get acquainted with technologies about the production of solar systems, evaluate the market in the Czech Republic and create a design of photovoltaic solar power station. Three designs of power stations were created with the help of the PV * SOL design system. Each design uses different photovoltaic cell technology. The result of each power station design is a complete finished project, which is based on many factors such as the efficiency of the entire system in a certain location, financial analysis, return on investment and more. In addition, these projects meet the conditions for the preparation of the subsidy program Nová zelená úsporám. At the end of the work, all three designed power stations are evaluated and with the help of multicriteria analysis, the best and most advantageous power station design for the given locality is determined. In the end, the idea of further development of the project is presented.

Design and Realization of Mobile Photovoltaic Power Station
Lednický, Ján ; Morávek, Jan (referee) ; Baxant, Petr (advisor)
This diploma thesis entitled Design and realization of a mobile photovoltaic power plant is dividet into two parts. In the first, theoretical part one can learn about the state of representation of renewable energy sources in the field of electrical power engineering and about the structure of photovoltaic power station systems. The secont part of this thesis is focused on the own design and realization of the mobile photovoltaic power plant, on the selection of individual suitable components and ther dimensioning. In addition, a model of a mobile power plant has been created, on the basis of which the power plant was constructed. Finally, one can find a source code analysis of a power plant monitoring using a microcontroler

Portable music player
Rozsíval, Adam ; Šotner, Roman (referee) ; Dřínovský, Jiří (advisor)
The thesis deals with the project of a portable music player with an amplifier in the class D. The device is powered up by connected power supply unit, eventually by built-in accumulator. Audio signal is played by bluetooth module, sound card or headphone output. Switching inputs and power supply of the accumulator is managed by a micro-controller. A correction equalizer for sound control is also embedded in the booster. All peripheries are put into a wooden baffle board. The sound is reproduced by a pair of loudspeakers.

Design and lay-out of high pressure pumping station.
Václavík, Tomáš ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
The aim of diploma thesis is design and lay-out of high pressure pumping station with plunger pumps for splash of scales from slabs of hot-rolled. Theoretic (introduction) part of this thesis contain description of formation of scales and description of ways how it is possible remove these scales. And this part contains also explication of effect of water jet on solid material. The practical part of diploma thesis is focused on design of pumping station including of dimensioning of machinery. Part of this work is also technical documentation for proposed pumping station and specification of main machines and devices.
