Integrace Španělska do EU / Spanish integration to the CEE

Müller, Tomáš January 2009 (has links)
My theses scope is description of the Spanish relationship to European Union from the first integration tendencies after the WW II till the preferential agreement ratification in 1970. I will try to analyze part of the Spanish economic history within the context of west-European integration. This period precedes the political transformation of autocratic Spain to modern democracy. These democratic cabinets were able to aspire seriosusly to fully-fledged European Union membership. In my opinion it is not possible to view political transformation as a start-up for democratically elected governments to setup new relationships with EU but it is necessary to understand it as an important condition which is part of a long-term process of Spanish convergence to west-European integration. In my theses I primarily concentrate on the economic development but I mean that it is important to mention the political situation as well.

Kroček, Tomáš January 2013 (has links)
This thesis covers the state assessment of the selected bank sections of dam reservoirs Vranov and Boskovice. Data used and processed in this thesis were acquired by visiting both sites several times in order to perform measurements and make photographic documentation. Futhermore, data on reservoirs' water levels from 2000-2011 provided by Povodí Moravy s.p. were used. In order to determine bank line regression, the above-mentioned data were processed using the Šlezingr's modification of the method of abrasion terminants determination. Results for dam reservoirs Vranov and Boskovice are then compared with results of dam reservoir Brno, which were produced by the author within the framework of his bachelor thesis using the same method. At the end of the thesis, the author presents several possible forms of stabilization and protection of disrupted banks of dam reservoirs, including their drawings.

Normál vlnové délky pro optické komunikace v pásmu C / Wavelength Standard for Optical Communication in C Band

Růžička, Bohdan January 2008 (has links)
The thesis presents design, development and realization of laser system with stabilized optical frequency which could become the basis of an etalon of wavelength for the telecommunication band of the near-infrared spectral region. Semiconductor DFB laser diode is used as a tunable source of radiation with narrow linewidth. Its optimum operation is ensured by especially designed current and temperature controller. The laser is prestabilized using FM spectroscopy technique to the passive Fabry-Perot cavity. This fast feed-back loop is able to improve spectral characteristics of the laser. The center frequency of the F.-P. cavity - the laser optical frequency is locked by a slow second feed-back loop to the absorption spectral line of acetylene 13C2H2 gas. The slow control loop is based on the third derivative spectroscopy technique. Relative stability at the level of 10E-12 was achieved.

Reaktivní zpracování polypropylénu / Reactive Modification of Polypropylene

Matláková, Jana January 2017 (has links)
The theoretical part describes the principles of the free-radical induced grafting and the influence of various parameters on the reactions course. The literature research summarizes the latest knowledge in the field of the reactive modification of polypropylene (PP), it is mainly focused on the PP modification using an unsaturated acid anhydrides. Theoretical part describes the various procedures and modification of technology in order to increase the grafting yield of maleation. The experimental part is determined by the influence of the stabilizers concentration, the peroxide structure, and the binary mixture of monomers on the grafting yield and the reaction course. In the first part, the critical stabilizers concentration was determined based on the experimentally obtained relationship between the grafting yield and the stabilizers concentration. A kinetic schema of grafting of MAH onto PP in the presence of stabilizers has been proposed and compared with the experimental results. The effect of the stabilizers on the extent of the undesirable b-scission was evaluated based on the melt flow rate (MFR) and the rheological curves of PP-g-MAH. In the second part, the effect of the peroxide structure and the concentration of reactants on the grafting yield of PP modification with MAH and itaconic anhydride (IAH) was observed. The initial grafting yield Rg has been experimentally determined and compared with a defined area of theoretical values of Rg. The extent of b-scission was significantly influenced by the structure and the concentration of peroxide, as shown by the results of MFR and the rheological curves of PP-g-MAH. The last part of the doctoral thesis is focused on the assessment of the combination of MAH and IAH as comonomers on the grafting yield. At first, the reference polymers were prepared using the solution polymerization of MAH, and IAH, and copolymerization of MAH with IAH. The reference polymers were analyzed by FTIR, DSC, WAXS to confirm the probable copolymerization of MAH and IAH. The dependence of the reaction enthalpy on the reaction time was observed using simulations of bulk polymerization of MAH, IAH and mixtures MAH and IAH "in situ" in isothermal calorimeter. PP was subsequently modified with a combination of MAH and IAH as comonomers in order to assess its effect on the grafting yield
