Serial communication
Novotný, Bohumil ; Šilhavý, Pavel (referee) ; Martinásek, Zdeněk (advisor)
Bachelor work is focused on the issue of a serial communication interface RS-232,USB, I2C and SPI, and also discusses the use of the laboratory module for experimental purposes. Laboratory module is designed with respect to the functional elements that will resist daily use of students. This work is detailed principles of serial communication in relation to each interface. The second part is devoted to method the module structure, functions of its individual components and functional solution output connectable to an oscilloscope and other measuring devices.

Economic aspects use of energy of photovoltaic plant
Cerman, Marek ; Procházka, Jiří (referee) ; Macháček, Jan (advisor)
The major topic of this master‘s thesis is to create a complex model of general photovoltaic power plant (PVP). First chapters are engaged in research of photovoltaic. Growth of globally installed power and analysis of situation in Czech Republic are described in this section. The spectrum of conditions is introduced, from current legislative framework up to local Sun radiation. The actual technologies and their advantages are depicted, especially rate of utilization of energy. Expected trends of future development of conversion efficiency are mentioned, with prediction of production costs of photovoltaic. In context with those aspects, the question of grid parity achievement arises. The own assembled model of photovoltaic power plant has been created in Microsoft Excel. The mathematical apparatus is described in a separate chapter, individually solving technical part, which main result – the amount of yearly generated electricity, is applied for economical calculation. Final results are the usual economic indicators, mainly: Net Present Value (NPV), Internal Rate of Return (IRR), Levelized Cost of Electricity (LCOE). There is series of aspects defined by user in the model which may impact the amount of produced electricity and economics of user’s project, such as use of loan, replacement of converters, operational costs etc. These aspects are frequently neglected by project sellers. In the end, intended photovoltaic power plants of 2.75 kWp and 28.98 kWp are simulated by the model in real conditions of 2013. Sensitivity of impact of both proposals to the aspects mentioned above has been analyzed. In the conclusion the achieved results are summarized and the key factors which determine the PVP’s economic efficiency are assessed.

Dodací parita a její vliv na stanovení ceny ? Incoterms v posledním znění
Török, David ; Malý, Josef (advisor) ; Bílková, Jana (referee)
Tato práce si dává za úkol shrnout a informovat o Incoterms, jako o nejrozšířenějších mezinárodně uznávaných pravidlech upravujících dodací doložku používaných v mezinárodním obchodě. Bude se zabývat zejména poslední verzí Incoterms, tedy Incoterms 2000. Dále v práci naleznete zhodnocení a komentáře k jednotlivým doložkám. Také upozorním na nebezpečí vyplývající z nevhodného použití některých doložek. V dalším oddíle bude vzorová kupní smlouva s komentáři a vysvětlivkami, které se budou vztahovat zejména k dodací doložce nebo odkazu na Incoterms. Dále na příkladu nabídky firmy BOHEMIA CARGO s.r.o. provedu srovnání cen, které zaplatí kupující a prodávající při různých dodacích paritách. Práce by měla pomoci případnému zájemci s výběrem vhodné doložky Incoterms.
