Calibration of weights and balances
Vojtová, Klára ; Zůda, Jaroslav (referee) ; Frk, Martin (advisor)
In the introductory chapter of this work is caught organizational structure of the national metrology system in the Czech Republic and its links to international organizations. There is indicated the basic terminology of metrology, particularly in the area of classification instruments. The following sections approaching the issue of measurement uncertainties, their classification, sources of uncertainty determined by the type A and B, their specifics and calculation. The above linked area already dealing with themselves calibrations, first of all calibration weights, classification of weights according accuracy classes, established procedures, and finally determining uncertainty in calibration weights. Then, immediately followed by a chapter dealing with calibration balances, performed tests and measurement uncertainties. The main part is of course directed towards the application of acquired knowledge to practical examples, thus performing the calibration weight class F2 using a high-precision weights, both in the premises of the Technical University in Brno, both in the laboratory weighing the Czech Metrological Institute. Further calibration was performed school balances Ohaus Explorer EX224.

Electronic circuits with fractal dynamics
Vojtová, Klára ; Guzan,, Milan (referee) ; Petržela, Jiří (advisor)
In the first section of this work is further analyzed the theories of differential equations and their computation and applications. The second part I addict to more detailed description of the Laplace transform, a sentence that is relevant to this area and also using the Laplace transform to solve electronic circuits. The third part of this project involves the theory of electronic circuits, especially the analysis and synthesis. The final and most important part is attended to circuits with fractal dynamics, design fractal approximation of the dynamics of capacitors in the frequency domain, has finally created its own electronic circuit measurement and evaluation results.
