This thesis deals with the optimization of power consumption in an intelligent digital home, where the appliances are powered either from a distribution network and also from the photovoltaic source owner. The optimization of consumption we will see both economically and in terms of load distribution network. Renewable power supply operates in a green bonus. Optimization is done using the backup system and the unit Home Manager by SMA. Backup system in collaboration with the batteries will store power from photovoltaic sources, if you're not consumed by appliances in the home. Since it may be a smart home, which is performed by means of inteligent wiring components and accessories (Inels system from the company ELKO EP), is possible thanks to intelligent multimedia extensions and appliances also optimizme consumption.

The aim of this work was to design and construct a simple audio amplifier, which would be based of involvement and components used in switching power sources on the maximum degree (for example from usual ATX sources for computer). The main motivation for development is the existence of many old sources that do not use and big interest of users for the construction of home audio amplifiers for small and medium power. Amplifiers based on switching power sources with greater efficiency and less weight than comparable classic amplifiers (working in classes A, B or AB). Their disadvantage is the complicated design and introduction of distortion and spurious signals to the amplified signal. This work will be described a design of simple amplifier, which will minimize these negative effects. For shortcomings and wrong parameters this proposed involvement will be eventually described and implemented design of amplifier in class D.

The aim of the Master´s thesis is proposing and implementation of computer controlled optical radiation source. The theoretical part describes the photometric, the radiometric quantities, applied components such as LED, the microcontroller and possible methods for the LED brightness control. The development of the device is described from the selection of the individual LEDs to the end of the device assembling and programing. On the several LEDs were made properties measurement. A circuit with microcontroller was designed and then was fabricated. The device was programmed for communication and control from the PC. The entire electronic is fitted in the metal frame of the construction box and finally the device functionality is tested.

This thesis deals with the design and construction of a single-phase switching power supply, which is intended for direct resistive heating of iron components. The power supply is especially intended for resistive heating of horse-shoes. The supply is able to deliver an output current of up to 1500 A at a power of up to 2500 W. The first part of this work deals with the design of individual parts of the unit, the second part is focused on construction and testing of the supply and the last part contains technical documentation. The power supply was successfully tested and the required output parameters were met. However some problems do exist, especially with overheating of the output rectifier and with contacting the heated component to the output leads of the supply. These problems will be discussed in the work. The power supply can be used as an alternative solution to classic means of iron heating. The methods and ideas presented in this work can be applied in a design of a similar power supply with high output current, but most of the design rules are valid generally for the given topology.

In the process of writing my diploma work I am going to focus on human resources in the company and I am going to put forward any proposals to their development and support. The main object of my work is to be granted subsidies from the European Union funds by means of accurately proposed operational programme.

This thesis focuses on the issues of project management and the application of procedures, processes and methodologies of project management in a particular case of the implementation of the requirement to create a new branch abroad - Innovation Box in the Netherlands. The company focuses on software development in the area of data security. Innovative center should serve the research and development of new potential products and services. The main output of the design is the Project Management Plan.

This diploma thesis deals with design of chiller for specific aplication – The City Theatre in Brno. The solving equipment of cooling appliance includes complete design of heat exchanger, battery cold and dimensioning of pipeline system used for various media. One part of design is also choice of individual coolant pumps, which guarantee necessary cirkulation of cooling medium in a certain pipeline routes. Selected battery cold in this administration reduced the size of the necessary cooling resources, therefore the cost of implementation. Everything is processed in calculating software. The resulting proposal is also drafted in the design program and will serve as one of the bases for subsequent implementation.

This diploma thesis deals with comparison of possible ways to supply the specific house by thermal energy. In the first part is a brief introduction of the building and determination of heat consumption. Following chapters are devoted to description and sorting of gas boilers, heat pumps, biomass boilers and solar collectors, inclusive the choice of specific source of heat. In the following part is stated economic evaluation of selected heat sources. Final part of the thesis is focused on design of additional exchanger instead of gas boiler.

A thorough description of the testing of a saddle-field ion source is presented in the diploma thesis. The most important experimental results, such as Faraday cup measurements of the ion beam current profile and of the ion energy spectra, are included. Based on these results it is shown that the optimized ion source works correctly and according to the expectations. At the end of the thesis, the development of the ion-optical and construction design of the focusing optics is described. The manufactured optics assembly attached to the ion source is also shown.

This magister’s thesis is about modern lighting of vehicles, the visual range and afterglow in poor visibility. The first part of the thesis provides a detailed analysis of the current situation and problems, including a comprehensive description of the sources of light radiation, lamps, structures, and describe the systems used in modern lighting technology of vehicles. In the second part of the thesis there are the scientific methods to determine the issue of visual range and afterglow of the headlights. The second part is about the application of acquired techniques to detect an afterglow and the visual range of vehicles with modern headlights with a light source with xenon lamp, compared with a vehicle with a halogen lamp and a vehicle with an older halogen headlight.
