Module of Digital Outputs with Modbus Communication
Vaško, Pavel ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Goal of mine bachelor’s thesis is create functional module of digital outputs, which can be seen in typical industry using. This module must contain communication interface on protocol Modbus and standard communication bus RS-232, RS-485. The module must be equipped with microcontroller series x51. Size of equipment must be minimalized into the smallest proportion. One part of the thesis is focused on theoretic information about Modbus protocol. Next parts contain charakteristics of communication and software facility.

Panel meassurement device
Vaško, Pavel ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
The master thesis includes a literature search, which is focused on questions around panel measure instruments for measuring analog voltage signals. There is the block diagram and the concept of measuring voltage values designed from collected information and defined requirements to the device. In the next step a design of the circuit diagram is created and published and consequently transferred into PCB. The whole board has been fabricated, assembled and tested. The firmware development starts with the definition of basic functional blocks for using of internal elements of the device, which is followed by the implementation of the Modbus slave station service routine. The top part presents graphical user interface on the device.

Professor Václav Vojtíšek: archivist from monarchy to socialism
Vaško, Pavel ; Čechurová, Jana (advisor) ; Pokorná, Magdaléna (referee)
This thesis deals with archivist and collage professor Václav Vojtíšek. It's structured chronologically with few thematic areas and was written mainly by positivistic method. Thesis draws from large base of archive resources and published materials. The goal of this thesis is to map Vojtíšek's academical and archivistic career during several regimes. It's not only concentrating on his professional career, but also depicts biographical themes. Key words Václav Vojtíšek, history of science, archivistic, Auxiliary Historical Science, Charles University, Czechoslovak science and art academy.
