Current loop 0(4) - 20 mA Analyzer
Mládek, Ondřej ; B:TECH,, Petr Dobrovolný, (referee) ; Kahle, Petr (advisor)
The subject of master´s thesis the problematics of current loop. Within the thesis, the basic components of current loop and the possibilities of its usage are described. There has also been an analysis made of the crucial functions of analyzer which is currently being in the process of development. A focus is put on mode of source and measure. The related functions are crucial in terms of testing and simulation of current loop. Furthermore, the SPI is described and it is used to establish access to the analyzer’s display. The usage of FMEA method has been chosen for the purpose of circuit’s reliability assessment. Practical part describes development of the analyzer and its parts. FMEA method application for selected fault states is presented in final part.

HMI for beverage filling machines
Mládek, Ondřej ; Sobotka, Milan (referee) ; Pásek, Jan (advisor)
The aim of my work is to create an application for control and visualization of beverage line. This work describes the advantages that automation brings into production. There is a description for worldwide used visualization programs InTouch, WinCC, Reliance 4 and Control Web. For completeness there are described Siemens visualization panels. New faceplate type objects were created in the program environment of WinCC flexible 2008 Standard for the individual machines of the line. Faceplates are used in visualization for 19" touch panel. Simulations is created in STEP 7 program. Data are collected in the .csv files. After that they are modified through the VBA macro.

The Internet in public libraries
Mládek, Ondřej ; Stöcklová, Anna (advisor) ; Pekárek, Aleš (referee)
(anglicky) The bachelor thesis deals with the issue of internet usage in public libraries. The bachelor thesis describes the following topics. Firstly, it describes the definition of the term "Internet" and its overall history and development. The second chapter deals mainly with legislative measures of providing access to information and the functioning of public libraries from domestic and foreign terms. Further work is devoted to projects internetisation, which took place in the Czech public libraries. The penultimate part of the work deals with the Internet services that libraries provide to its users and the future of the Internet in the libraries of the Czech Republic. The last part includes the evaluation of survey that was focused on the Internet usage in public libraries.
