More than twenty years after the independence declaration, Republic of Croatia is facing the second biggest step in its history- entry to the European Union. European Union, the world's trade leader, has recognized Croatia as a reliable partner in the future affairs. Croatia shall become a 28th member of the integration on July 1st, 2013. Croatia has experienced many obstacles on the path to the European Union, trying to align its system with the EU's comprehensive legislation. The aim of this thesis is therefore to provide an extensive analysis of the Croatian path to the European Union and to apply the solutions on the further development not only of Croatia but also the remaining candidate countries of the European Union.

This thesis focuses on deterministic chaos and selected methods of chaos control. It briefly describes the matter of deterministic chaos and presents commonly used tools of analysis of dynamical systems exhibiting chaotic behavior. A list of frequently studied chaotic systems is presented and followed by a description of methods of chaos control and the optimization of these methods. The practical part is dedicated to the stabilization of two model systems and one real system with described methods.

Nowadays, efforts are being made to reduce the environmental impact on the planet even at soils management. Excavated soils are treated as waste and often end up in landfill or depot landfills. It is an effort to exploit these soils. By adding suitable stabilizing additives, features such as yield fluidity, moisture or compressive strength can be adjusted. This composite can be further liquefactioned by using water and suitable liquefiers or plasticizers. Such iquefactioned soils are a suitable self-compacting grouts dressing for excavation for the laying of utility grids, where it is necessary to fill the hole again. The advantage are low economic demands and the absence of excess waste. In the course of this thesis the situation of soil usability in the Czech Republic will be evaluated and possible technologies of soil adjusters will be described. Further, the known types of stabilizing additives and their influence on soil stabilization will be evaluated and verified. Then, different types of liquefying additives will be evaluated and verified. The aim of the thesis is to develop a new technology of liquefaction and soil stabilization.

This diploma thesis is focused on sludge management of wastewater treatment plant. The research work contains an overview of the related legislation, outlines the problems of sludge treatment in the Czech Republic and also deals with technologies and technical solutions that are related to the processing and treatment of sewage sludge for various size categories of wastewater treatment plants. The second part is devoted to the technical and economic assessment of wastewater treatment plants in the category from 500 EO to 2 000 EO. The assessment is based on real data provided by WWTP operators and focuses on electricity consumption, investment costs and operating costs. Part of the diploma thesis is also determining the rentability of drainage equipment, and studying the convenience of using mobile or stationary drainage equipment.

Dizertační práce se zabývá procesy, které jsou řízeny systémy zpožděných diferenciálních rovnic $$x'(t) =f(t,x_t,u),\,\,\,\, t\ge t_{0}$$ kde $t_0 \in \mathbb{R}$, funkce $f$ je definována v jistém podprostoru množiny $[t_0,\infty)\times {C}_{\tau}^{m}\times {\mathbb{R}}^r$, $m,r \in \mathbb{N}$, ${C}_{\tau}^{m}=C([-\tau,0],{\mathbb{R}}^{m})$, $\tau>0$, $x_t(\theta):=x(t+\theta)$, $\theta\in[-\tau,0]$, $x\colon [t_0-\tau,\infty)\to \mathbb{R}^{m}$. Za předpokladu $f(t,\theta_m^*,\theta_r)=\theta_m$, kde ${\theta}_m^*\in {C}_{\tau}^{m}$ je nulová vektorová funkce, $\theta_r$ a $\theta_m$ jsou $r$ a $m$-dimenzionální nulové vektory, je říd\'cí funkce $u=u(t,x_t)$, $u\colon[t_0,\infty)\times _^\to \mathbb^$, $u(t,_m^*)=\theta_r$ určena tak, že nulové řešení $x(t)=\theta_m$, $t\ge t_-\tau$ systému je asymptoticky stabilní a pro libovolné řešení $x=x(t)$ integrál $$\int _{t_}^\omega \left(t,x_t,u(t,x_t)\right)\diff t,$$ kde $\omega$ je pozitivně definitní funkcionál, existuje a nabývá své minimální hodnoty v daném smyslu. Pro řešení tohoto problému byla Malkinova metoda pro obyčejné diferenciální systémy rozšířena na zpožděné funkcionální diferenciální rovnice a byla použita druhá metoda Lyapunova. Výsledky jsou ilustrovány příklady a aplikovány na některé třídy zpožděných lineárních diferenciálních rovnic.

Diplomová práce pojednává o teorii chaotických dynamických systémů, speciálně se pak zabývá Rösslerovým systémem. Kromě standardních výpočtů spojených s bifurkační analýzou se práce zaměřuje na problém stabilizace, konkrétně na stabilizaci rovnovážných bodů. Ke stabilizaci je využita základní metoda zpětnovazebního řízení s časovým zpožděním. Významnou část práce tvoří zavedení a implementace obecné metody pro hledání vhodné volby parametrů vedoucí k úspěšné stabiliaci. Dalším diskutovaným tématem je možnost synchronizace dvou Rösslerových systémů pomocí různých synchronizačních schémat.

The increasing volume of waste of all kinds is currently a phenomenon of economically developed society and one of the problems of environmental protection. It is therefore imperative, in the interest of sustainable development, to monitor impacts related to the impact on our ecology, to regulate waste production by legislation and universally promote their reuse and recycling. Construction and demolition waste occupy a significant share of the total waste volume. This category also includes excavated soils. Recycling of these materials could significantly reduce the amount of landfilled waste and at the same time, these materials could be used as an important source of secondary raw materials. The doctoral thesis describes the research and development of the new technology of reuse soils in the form of self-compacting grouts. The result of the solution will be a suspension of optimal rheological properties, providing a perfect leaking around the stored utility networks. Emphasis will be placed on the study of the interaction of different types of soils with the stabilizers, flowable or plasticizing additives and its typical dispersible substance, including verification of the developed technology in situ.

Goal of this semestral thesis is development of chassis electronic stability control ESP. Thesis analyze kinematic model of chassis, design of dynamic model, which is used for simulation of designed systems. Final system will be used in Formule Student monopost.

In this master thesis I have been dealt with the design and construction of an instrumental platform that used positioning focused laser beam (so-called optical tweezers) for manipulation with living cells without their damage.

The main aim of the thesis is a frequency stabilization of the DFB semiconductor laser diodes. The temperature stability of the laser diode chip, the stability and the noise of the injection current and the backward reflections are the crucial parameters which affects the frequency stability. These influences are described and the resolution is proposed. The theory of the external methods of the frequency stabilization and the comparison of these methods is presented. One method was choosed and this method was realized for 760 and 1540 nm wavelength laser diodes. In this method was used the frequency stabilization based on the linear absorption to the spectral lines of the gases. The diploma work is closed by the measured results of the frequency stability of the used laser diodes and by the comparison of level of stability achieved by the other methods.
