This thesis deals with the matter of risk managament in IT projects. It explains the importance of risk management in such projects and shows different ways and methods of managing and analyzing the risks. After explaining the basic concepts and the various phases of risk management the text focuses on two methods of risk analysis - the fault tree analysis of event tree analysis. Use of both methods is explained for both quantitative and qualitative analyses. The second half of the work includes the design of an application for the support of risk analysis employing the methods of fault tree analysis and event tree analysis. This is followed by a description of the implementation of the proposed system in a web environment using jQuery, Nette Framework and Dibi.

This thesis deals with ray tracing methods and their acceleration. It gives partial study and review of algorithms from classical ray shooting algorithm to recursive approach up to distributed ray tracing algorithm. Significant part of this thesis is devoted to BSP tree structure and its subclass of k-D tree, it shows simple algorithm for its construction and traversal. The rest of thesis is dealing with k-D tree construction techniques, which are based on the right choice of the splitting plane inside the every cell of k-D tree. The techniques upon the thesis is based on are space median, object median and relatively new cost model technique named SAH, otherwise as surface area heuristic. All three techniques are put into testing and performance comparison. In the conclusion the results of tests are reviewed, from where SAH is coming out as a winner.

This work deals with the symbolism of trees in the Old Testament considering the mythology of the ancient Near East, using relevant literature, concordant exploration, and synchronic and diachronic analyses of biblical texts. It aims to present an intersection of the most important aspects of the appearance of trees in the Scripture, both in a literal and figurative sense. Drawing on work with biblical and mythological texts from the ancient Near East, it presents the tree as a comprehensible symbol with strong explanatory power, which constitutes its potential to contain even the most complex messages of the Scripture and of the human condition as such.

The aim of this thesis is to bring together two areas of the graph theory. We first give a brief exposition of graph homomorphisms and related notions that directs to the definition of the replacement operation by using an appropriate replacement graph. The tree-depth is investigated as one of considerable chara- cteristics of each graph. Finally we focus on category representations in the category Graph of all finite graphs and Graphk of all finite graphs with tree-depth at most k.

Gegenstand der vorliegenden Arbeit ist die ortsaufgelöste Untersuchung der Schichtdicke und der elektrischen Eigenschaften von Funktionsschichten in gedruckten Polymersolarzellen. Die massendrucktechnische Realisierung der großflächigen Polymersolarzellen mit dem Schichtaufbau Zink/ZnO/P3HT:PCBM/PEDOT:PSS erfolgt im Tief- und Siebdruckverfahren auf einem papierbasierten Bedruckstoff. Die gedruckten Funktionsschichten werden mit verschieden optischen und elektrischen Messverfahren charakterisiert und die Eignung der Verfahren wird diskutiert. Abschließend wird die gesamte Polymersolarzelle mit einer Kombination aus spektraler und elektrischer Messung positionsgenau untersucht. Dadurch kann ein Zusammenhang zwischen den Solarzelleneigenschaften und den ortsaufgelösten Messwerten aufgezeigt werden. / The aim of this work is the space-resolved investigation of the layer thickness and the electrical properties of functional layers in printed polymer solar cells. The realization of the large-area polymer solar cells with a layer structure of zinc/ZnO/P3HT:PCBM/PEDOT:PSS occurs by gravure and screen printing on a paper-based substrate. The printed functional layers are characterized by different optical and electrical measurement methods and the suitability of these methods is discussed. Finally, the complete polymer solar cell is examined dependent on a position by using a combination of spectral and electrical measurement techniques. With this analysis a correlation between the solar cell characteristics and the space-resolved measurements can be shown.

This master's thesis is divided into three parts. In the first part I described P2P lending, its characteristics, basic concepts and practical implications. I also compared P2P market in the Czech Republic, UK and USA. The second part consists of theoretical basics for chosen methods of machine learning, which are naive bayes classifier, classification tree, random forest and logistic regression. I also described methods to evaluate the quality of classification models listed above. The third part is a practical one and shows the complete workflow of creating classification model, from data preparation to evaluation of model.

The thesis analyzes and interprets selected landscape motifs corresponding with biblical symbols in the first three collections of poetry of catholic author Václav Renč. The aim of this thesis is to give an opinion on my hypothesis that biblical symbol is a competent way of interpretation Bremond's pure poetry, and to evaluate the competence of Renč's poetry belonging to the concept of pure poetry. Also defining the limits of pure poetry through a comparison with the fourth Renč's collection which already shows significant changes in it's poetics. The theoretical part is focused on contemporary and modern literary-scientific views on Václav Renč's work, on the concept of poetry provided by Bremond, his reception in our backround and the role of the symbol in pure poetry. The thesis methodologically works with the symbol in connection with Zdeněk Mathauser's theory of a circle symbol that best corresponds with Bremond's understanding of poetry and is considered as the essential base of the theory of pure poetry. The practical part discusses the crucial landscape symbols (earth, flower and fruit, bush and tree) in single collections based on biblical interpretation and then describes their transformation in each of them. The conclusion of the confrontation with the next and at the same time the...

The transition of the North African electricity system towards renewable energy technologies is analyzed in this thesis. Large potentials of photovoltaics (PV), concentrating solar power (CSP) and onshore wind power provide the opportunity to achieve a long-term shift from conventional power sources to a highly interconnected and sustainable electricity system based on renewable energy sources (RES). A multi-dimensional analysis evaluates the economic and technical effects on the electricity market as well as the socio-economic impact on manufacturing and employment caused by the large deployment of renewable energy technologies. The integration of renewable energy (RE) into the electricity system is modeled in a linear optimization model RESlion which minimizes total system costs of the long-term expansion planning and the hourly generation dispatch problem. With this model, the long-term portfolio mix of technologies, their site selection, required transmission capacities and the hourly operation are analyzed. The focus is set on the integration of renewable energy in the electricity systems of Morocco, Algeria, Tunisia, Libya and Egypt with the option to export electricity to Southern European countries. The model results of RESlion show that a very equal portfolio mix consisting of PV, CSP and onshore wind power is optimal in long-term scenarios for the electricity system. Until the year 2050, renewable energy sources dominate with over 70% the electricity generation due to their cost competiveness to conventional power sources. In the case of flexible and dispatchable electricity exports to Europe, all three RE technologies are used by the model at a medium cost perspective. The socio-economic impact of the scenarios is evaluated by a decision model (RETMD) for local manufacturing and job creation in the renewable energy sector which is developed by incorporating findings from expert interviews in the RE industry sector. The electricity scenarios are assessed regarding their potential to create local economic impact and local jobs in manufacturing RE components and constructing RE power plants. With 40,000 to 100,000 new jobs in the RE sector of North African countries, scenarios with substantial RE deployment can provide enormous benefits to the labor market and lead to additional economic growth. The deployment of renewable energy sources in North Africa is consequently accelerated and facilitated by finding a trade-off between an optimal technology portfolio from an electricity system perspective and the opportunities through local manufacturing. By developing two model approaches for evaluating the effects of renewable energy technologies in the electricity system and in the industrial sector, this thesis contributes to the literature on energy economics and energy policy for the large-scale integration of renewable energy in North Africa.
