Orienteering club support system
Buk, Jindřich ; Vojíř, Stanislav (advisor) ; Sklenák, Vilém (referee)
Nowadays, an increasing number of processes and life situations is getting IT support. Often the use of the Internet aims to accelerate and simplify existing processes. In addition, there is a big area of social networking that can be complementary. This thesis deals with the possibilities of using web technologies to support the running of a club and its subsequent development. Indeed, the club has the potential to simplify and automate many processes which previously have been carried out by someone in person. It has also a potential to use social networks for its publicity and development. The aim is to first determine what areas of the clubs operations are the most appropriate to be supported by any information system. Another objective is to find out how other clubs already integrate any information systems. The final objective is to design and create a specific application. The first two objectives are addressed through a survey among the leaders of the biggest Czech clubs. Indeed in these clubs, the use of automation and simplification of existing processes could have a great potential. The proposal for a specific application is then based on the previous survey and the field experience of the author. While serving many existing processes in running the club, the proposed application adds many elements of social networking.

Kyzivát, Marek ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
The thesis describes the initial state of the computer network Basic Schools and Kindergartens Ohradní (ZŠMŠ Ohradní) in Prague 4 and then its reconstruction, which I largely contributed. ZŠMŠ Ohradní consists of four pavilions and from one building on the other side of the street. The aim of this study is to assess the initial state of the network and point out the shortcomings that we discovered. We found deficiencies in the operation stress tests, measurements and data cabling overall analysis. Original networks connectivity was 100Mb/s. Together with a colleague, we are network administrators. Furthermore, I am going to introduce a new form of network, which has identified deficiencies improved, by using on newer technologies. I will describe its structure, address allocation, active and passive components, and operated services. New network is capable of 1Gb/s, and its spine is going to be 10Gb/s soon. Benefits of this reconstruction is faster, more stable and more modern network that will facilitate the work of employees of ZŠMŠ Ohradní. To these improvements, I have mainly contributed by measurements. I participated in the design and implementation of new form of data network. I collaborated with fellow Poc to the configuration of active elements and network services in reconstructed network.

Grycová, Adéla ; Rolenc, Jan Martin (advisor) ; Cibulková, Petra (referee)
The thesis deals with the issues of framing and europeanization of the foreign policy of the European Union in the context of an actorness of the EU. These two theoretical concepts are applied on the case of an approach of the Czech Republic and European Union towards Russian Federation during the crisis in Ukraine. The aim of this thesis is to find out if the European Union is capabble of affecting the behaviour of a member state in order to create unified and operational foreign policy. The first chapter deals with teoretical definition of the two concepts and detailed description of the stances of Czech Republic and European Union follows in the second one. On the basis of these chapters the assessment is conducted. The last part firstly concludes if any attempt of influecing is present and secondly the success rate of the attempt is evaluated.

The thesis deals with the functioning of depositories in the enviroment of the Czech market from the perspective of legislative and practical. The introduction is devoted to directives that make up a harmonized legal framework and the Czech legislativ, which specifically prescribes behaving of depositories. The main part is devoted to the depositary functions, such as operating in the Czech market conditions. This part of work is focused not only on the distribution of the depositary market, but also on the collected amount of the fees, the efficiency of regulation in the real market enviroment and in the importace of depositories in the Czech market. The final section is devoted to the findings, including the final assessment of the depositaries. As a first of its kind, this thesis gives a comprehensive view of activity of depositories and their importace for the Czech market, as the depositaries represent entities that control whether funds act in accordance with the legislation. Depository oversees as to prevent fraud and to qualified investors or collective investment contributed to the further development of the capital market, which is necessary for the further development of all economic sectors.

Modelling, parameter estimation, optimisation and control of transport and reaction processes in bioreactors.
ŠTUMBAUER, Václav
With the significant potential of microalgae as a major biofuel source of the future, a considerable scientific attention is attracted towards the field of biotechnology and bioprocess engineering. Nevertheless the current photobioreactor (PBR) design methods are still too empirical. With this work I would like to promote the idea of designing a production system, such as a PBR, completely \emph{in silico}, thus allowing for the in silico optimization and optimal control determination. The thesis deals with the PBR modeling and simulation. It addresses two crucial issues in the current state-of-the-art PBR modeling. The first issue relevant to the deficiency of the currently available models - the incorrect or insufficient treatment of either the transport process modeling, the reaction modeling or the coupling between these two models. A correct treatment of both the transport and the reaction phenomena is proposed in the thesis - in the form of a unified modeling framework consisting of three interconnected parts - (i) the state system, (ii) the fluid-dynamic model and (iii) optimal control determination. The proposed model structure allows prediction of the PBR performance with respect to the modelled PBR size, geometry, operating conditions or a particular microalgae strain. The proposed unified modeling approach is applied to the case of the Couette-Taylor photobioreactor (CTBR) where it is used for the optimal control solution. The PBR represents a complex multiscale problem and especially in the case of the production scale systems, the associated computational costs are paramount. This is the second crucial issue addressed in the thesis. With respect to the computational complexity, the fluid dynamics simulation is the most costly part of the PBR simulation. To model the fluid flow with the classical CFD (Computational Fluid Dynamics) methods inside a production scale PBR leads to an enormous grid size. This usually requires a parallel implementation of the solver but in the parallelization of the classical methods lies another relevant issue - that of the amount of data the individual nodes must interchange with each other. The thesis addresses the performance relevant issues by proposing and evaluation alternative approaches to the fluid flow simulation. These approaches are more suitable to the parallel implementation than the classical methods because of their rather local character in comparison to the classical methods - namely the Lattice Boltzmann Method (LBM) for fluid flow, which is the primary focus of the thesis in this regard and alternatively also the discrete random walk based method (DRW). As the outcome of the thesis I have developed and validated a new Lagrangian general modeling approach to the transport and reaction processes in PBR - a framework based on the Lattice Boltzmann method (LBM) and the model of the Photosynthetic Factory (PSF) that models correctly the transport and reaction processes and their coupling. Further I have implemented a software prototype based on the proposed modeling approach and validated this prototype on the case of the Coutte-Taylor PBR. I have also demonstrated that the modeling approach has a significant potential from the computational costs point of view by implementing and validating the software prototype on the parallel architecture of CUDA (Compute Unified Device Architecture). The current parallel implementation is approximately 20 times faster than the unparallized one and decreases thus significantly the iteration cycle of the PBR design process.
