Wireless sensor network
Šťáva, Radek ; Šteffan, Pavel (referee) ; Pavlík, Michal (advisor)
The main theme of this work is to design and make a modern network of wireless sensors, when the main used circuit in the sensor module and the receiver module is microcontroller Texas Instruments CC430F513x. Care is taken primarily at very low power of sensor module for long battery life when on battery power. It is also emphasis is on reliability involvement of miniature size, expandability and high precision modules of basic sensors.

Web Application for Monitoring of Elecric Energy Consumption
Režný, Jan ; Koutný, Martin (referee) ; Šimek, Milan (advisor)
Bachelor thesis called „Web Application for Monitoring of Elecric Energy Consumption“ focuses on receiving, processing and visualization of measured values from wireless sensor network, which is measuring the consumption of electrical devices. The aim is to create a applications for data receiving and proccessing and application which can manage connected power meters, user-defined devices and its association, export measured data and display reports, graphs and statistics obtained from these measured values.

Sector coupling and the future form of the electricity and gas sectors
Švéda, Miroslav ; MA, Martin Šik, (referee) ; Radil, Lukáš (advisor)
This thesis deals with Sector coupling problematics. First, it deals with the development and present situation in the generation and consumption of electric power and the development and present situation in the extraction and consumption of natural gas in the Czech Republic and in the European union. Further, the thesis deals with Sector coupling, this concept is explained, and it is adumbrated what questions it deals with. Then, the technologies that can be achieved in the future of Sector coupling are introduced. Pilot projects of these technologies are presented as part of the discussion about these technologies. Finally, a consideration of the future use of Sector coupling technologies in the Czech Republic is given.

The partial model of sewage treatment plant
Novák, Petr ; Ptáček, Michal (referee) ; Radil, Lukáš (advisor)
The thesis deals with wastewater treatment plants (WWTPs). For the energetic self-sufficiency of the WWTP, it is necessary to study the operational background, equipment and their possible operational prediction for energy distribution over time and adaptation to any renewable energy (RES). It is also possible to optimize the operation to maximize the equalization of the input power. We're talking about small WWTPs up to 500 EP. Large purification blocks are also an option. The student will evaluate the current state of knowledge and try to design and possibly implement the financial savings of the given concept.

Measurement of basic electrical variables on drives of LV circuit breakers
Mazálek, Tomáš ; Valenta, Jiří (referee) ; Bušov, Bohuslav (advisor)
This thesis has been created for the purpose of comparing calculated values by oscilloscope and by Excel. There is also introduced the procedure calculating the maximum generated power by using macros in Excel. For this it was necessary to show a theory of electrical values of non-sinusoidal and aperiodic signal. There has been shown the methods of measuring of power consumption on motor operator for acquisition of relevant data. My thesis brings a wide overview, which is connected with motor operators. I am analyzing a principle of motor operator, methods of right measuring and I am describing a transfer of kinetic energy from driving motor to contacts of circuit breaker

Entrepreneurial Intention of Business Development
Hicl, Lukáš ; Jakubcová, Marie (referee) ; Bartoš, Vojtěch (advisor)
This bachelor thesis deals with the development of the already established company Poštor Ltd.. It describes Poštors problems and possible solutions since the introduction of web pages and the implementation of another information system to a total reorganization of the company into a modern concept. I analyse the various world markets of wine and the exploitable potential in the terms of suppliers and customers.

Energy sources and consumption
Majer, Jan ; Kuba, Pavel (referee) ; Bobák, Petr (advisor)
The thesis describes basic methods of producing energy and presents the basic division and characterize sources of energy. It compares and describes the production of energy in the Czech Republic and the United States of America. The thesis explains, where and how is this energy consumed and presents energy production and consumption in the Czech republic and in the United States of Amerika and provides a comparison of the two countries. Indicates the percentage of consumption in various sectors in these countries and the distribution of energy consumed by resource used. The thesis is also focused on the comparison of household consumption in the Czech Republic and the United States of America. It specifies the average household consumption of Prague and New York and investigates the causes of the difference in average household consumption of both countries.
