The use of nanofibres strain gauges for construction of linear sensors
Kirchner, Jan ; Kůr, Jan (referee) ; Pernikář, Jiří (advisor)
The aim of this thesis was to determine the basic characteristics of behavior of nanofiber strain gauges and on the basis of experimental measurements to confirm the suitability of the design of the length sensors. There was a product designed with a swivel arm whose rotation burdens the nanofiber strain gauge affixed to the flat side of the cut. Some measurements were carried out to find out a suitable direction of the loading pressure and to reveal the area showing the linear behavior. This linear area is approximately between 44 ÷ 92 % of the range of the nanostrain gauge (0% maximum load tensile, 100% maximum load pressure). Other measurements dealt with temporal stability of the output value at each point. The outcome of these experiments was to determine the methodology and to propose the design of sensors for further tests, the aim of which was to develop a sensor for measuring small diameters (from 1 to 5 mm).

Conservative Discontent with Liberal Democracy. Carl Schmitt and Ernst Jünger
Kúr, Jiří ; Znoj, Milan (advisor) ; Bíba, Jan (referee)
Liberal democracy is a representative goverment that combines the principles of liberal and democratic. The Bachelor thesis will be devoted to conservative criticism of the political system, which in the days of the Weimar Republic in german enviroment was formulated by Carl Schmitt and Ernst Jünger. The Weimar republic for the time of its functioning, in the period after the World War I and in the 30's, was under pressure from the extreme left and the right, immedidiately threatened its existence. On this critism of the serious crisis of the state responded Carl Schmitt in his work. The key work in this regard is the Concept of Political, which is reviewed by Ernst Jünger. This creates a critical dialogue framed by the German Conservative Revolutionary movement, criticising fragile democracy of the Weimar Republic and the leveling collectivism, the triumf of the masses of the individuals and the common man dictatorship, and the pluralism, which is a direct consequence of the deformation and degradation of parlamentarism. Key words Carl Schmitt, Ernst Jünger, the political, conservatism, nationalism, German Conservative Revolution, The Weimar Republic, crisis of parliamentarism, critique of liberal democracy

Automatic system for gauge blocks calibration optimized for legal length metrology
Buchta, Zdeněk ; Šarbort, Martin ; Čížek, Martin ; Hucl, Václav ; Řeřucha, Šimon ; Pikálek, Tomáš ; Dvořáčková, Š. ; Dvořáček, F. ; Kůr, J. ; Konečný, P. ; Lazar, Josef ; Číp, Ondřej
This paper presents a contactless system for automatic and contactless gauge blocks calibration based on combination of laser interferometry and low-coherence interferometry. In the presented system, the contactless measurement of the absolute gauge block length is done as a single-step operation without any change in optical setup during the measurement. The optical setup is combined with compact gauge block changer with capacity 126 gauge blocks, which makes the resulting system fully automatic. \nThe paper also presents in detail a set of optimization steps which have been done in order to transform the original experimental setup into the automatic system which meets legal length metrology requirements. To prove the measurement traceability, we conducted a set of gauge block length measurement comparing data from the optimized system and the established reference system and TESA–UPC operated in Czech Metrology Institute laboratory.
