Programs and Algorithms of Numerical Mathematics 18 : Janov nad Nisou, June 19-24, 2016 : proceedings of seminar
Chleboun, J. ; Kůs, Pavel ; Přikryl, Petr ; Segeth, Karel ; Šístek, Jakub ; Vejchodský, Tomáš
This book comprises papers that originated from the invited lectures, survey lectures, short communications, and posters presented at the 18th seminar Programs and Algorithms of Numerical Mathematics (PANM) held in Janov nad Nisou, Czech Republic, June 19-24, 2016. All the papers have been peer-reviewed. The seminar was organized by the Institute of Mathematics of the Czech Academy of Sciences under the auspices of EU-MATHS-IN.cz, Czech Network for Mathematics in Industry. It continued the previous seminars on mathematical software and numerical methods held (biennially, with only one exception) in Al šovice, Bratří kov, Janov nad Nisou, Ko řenov, L ázně Libverda, Dolní Maxov, and Prague in the period 1983-2014. The objective of this series of seminars is to provide a forum for presenting and discussing advanced theoretical as well as practical topics in numerical analysis, computer implementation of algorithms, new approaches to mathematical modeling, and single- or multi-processor applications of computational methods.

These proceedings contain peer-reviewed papers that are based on the invited lectures, survey lectures, short communications, and posters presented at the 19th seminar Programs and Algorithms of Numerical Mathematics (PANM) held in the International Center for Spiritual Rehabilitation, Hejnice, Czech Republic, June 24-29, 2018. The seminar was organized by the Institute of Mathematics of the Czech Academy of Sciences under the auspices of EU-MATHS-IN.cz, Czech Network for Mathematics in Industry, and with the financial support provided by the RSJ Foundation. It continued the previous seminars on mathematical software and numerical methods held (biennially, with only one exception) in Alšovice, Bratříkov, Janov nad Nisou, Kořenov, Lázně Libverda, Dolní Maxov, and Prague in the period 1983-2016. The objective of this series of seminars is to provide a forum for presenting and discussing advanced topics in numerical analysis, computer implementation of numerical algorithms, new approaches to mathematical modeling, and single- or multi-processor applications of computational methods.

White Omsk and Czechoslovak legion
Chleboun, Jan ; Tumis, Stanislav (advisor) ; Vojtěchovský, Ondřej (referee)
The thesis deals with the Czechoslovak garisson and the diplomatic representation in Omsk during the Russian Civil War and the anti-bolshevik governments in the city (1918-1919). It focuses on the local events through the opticians mentioned above, evaluates and analyzes their role, attitudes, everyday life and relations with the White governments and the domestic population. The work is primarilly based on the study of archive sources, periodicals and memories of the participants.

Fourier-Galerkin Method for Stochastic Homogenization of Elliptic Partial Differential Equations
Vidličková, Eva ; Zeman, Jan (advisor) ; Chleboun, Jan (referee)
This thesis covers the basics in the stochastic homogenization of elliptic partial differential equations, from underlying theory up to numerical ap- proaches. In particular, we introduce and analyze a combination of the Fourier-Galerkin method in the spatial domain with a collocation method in the stochastic domain. The material coefficients are assumed to depend on a finite number of random variables. We present a comparison of the Monte Carlo method with the full tensor grid and sparse grid collocation method for two applications. The first one is the checkerboard problem with continuous random variables, the other considers the material coefficients to be described in terms of an autocorrelation function.

Russian civil war. Reflections in the Czechoslovak society (1918-1921)
Chleboun, Jan ; Šedivý, Ivan (advisor) ; Michela, Miroslav (referee)
This work deals with the reflection of Russian civil war (1918-1921) in Czechoslovak society. It focuses on the media presentation of the warring oponents, on the changes of this image during the conflict, as well as on the contemporary war reporting and public awareness. It also explores attitude of different groups of inhabitants and representatives of the state, as well as the influences and connections between events in Czechoslovakia and Russia. The work is mainly based on the research in contemporary press and various publications.

Interbank contagion under the Basel III regulatory framework
Chleboun, Jakub ; Jakubík, Petr (advisor) ; Lešanovská, Jitka (referee)
This study assesses the impact of the Basel III regulatory framework on interbank contagion. It focuses on the direct interbank contagion that spreads via interbank foreign claims among national banking sectors. A balance sheet-based network model employs the quarterly consolidated banking statistics, collected by the Bank for International Settlements, to simulate the consequences of credit and funding shock under stressed market conditions. Compared to the Basel II, the Basel III regulatory framework reduces the probability of interbank contagion (following a simulated default of one banking sector) from 31% to 14% and lowers the impact of contagion by 63% in terms of average loss for a banking sector. The simulations under both regulatory frameworks show that relatively smaller banking sectors can trigger severe interbank contagion comparable to large banking sectors. Throughout the 2005-2009 period, the Basel III regulatory framework stabilizes the fluctuations of the scope of interbank contagion.

Numerical modeling of magnetostrictive materials
Kholmetska, I. ; Chleboun, J. ; Krejčí, Pavel
An operator-differential model for magnetostrictive energy harvesting proposed in the literature is used to calculate the amount of harvested energy under some uncertainty in the Preisach density function. The uncertainty is modeled through a fuzzy set approach. In galfenol, an alloy of gallium and iron, however, the hysteresis phenomenon is present only weakly. This allows to propose a simpler, but computationally faster model without hysteresis. The new, simpler model has been identified from the measured magnetic and magnetostrictive cycles. The amount of harvested energy is of the same order in both models. Again, an uncertainty in the identified model can be considered and its impact on the amount of the harvested energy calculated.

Spectral characteristics in fiber optics
Chleboun, Jiří ; Tejkal, Vladimír (referee) ; Šporik, Jan (advisor)
This bachelor’s thesis is focused on the influence of attenuation and dispersion glass and plastic optical fibers in optical transmission system. Theory of optical transmission is discussed in the theoretical part, it is defined term like spectral attenution characteristic and its division into transmission bands. Sources and detectors are itemized further, which are used for optical transmissions in fiber optics. The thesis describes the most occured effects, which influenced transmission parameters of optical fiber, like optical attenution, dispersion and aspectual polarization dispersion. Theory of plastic optical fibers is processed at the end of theoretical part of thesis. It is also processed advantages, disadvantages and useage of plastic optical fibers and they are consequently compare with glass fibers. Comparison is focused mainly on attenuation, transmission properties and useage on these types of fibers in telecommunication. Representation of spectral attenution characteristics in programme MATLAB is practical output of the bachelor´s thesis. Created programme approximates points which are got from measure optical attenuation by the Lagrange interpolation polynomial.
