Strain stress analysis of BS splint
Řehák, Kamil ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
This master‘s thesis deals with strain-stress analysis of hip joint together with the final applied total endoprosthesis with Burch-Schneider cage. The main point of my work was to find the solution of stress–strain analysis state, which has been mentioned before in connection with Burch-Schneider cage. I describe the technique of geometric creation of whole body system, component´s materials or conditions which are neccessary for calculation. In coclusion there are results achieved in variants. In the first option the case of bone tissue was considered, which don’t reach degradation mechanical properties effect straining under Burch-Schneider cage. In some cases when the bone tissue is untimely forced, the necrosis of bone tissue takes place under Burch-Schneider cage. This possibility is described in the second option of type. For every option there was a case which was calculated with applied screw or without it. In all option mechanical features of cancellous bone tissue and their change influence on achieved results were considered. This problem was solved computational simulation in commercial software Ansys Workbench 12.0.

The occurrence of word-initial glottalization in Slovak English
Uhrinová, Mária ; Skarnitzl, Radek (advisor) ; Popelíková, Jiřina (referee)
The occurrence of word-initial glottalization in Slovak English Mária Uhrinová Praha, 2012 Abstract The features of prosodic structure were shown to influence the occurrence of word-initial glottalization in English. The aim of the present thesis is to analyze the occurrence of glottalization in word-initial vowels in Slovak English in relation to prosodic structure, specifically to word stress and position in the intonational phrase. The semantic status of words (lexical vs. grammatical) is also considered. The first part provides a brief overview of key concepts in second language acquisition with focus on acquisition of second language phonology. In addition, a summary of previous research on glottalization is given. The empirical part of this thesis is based on the recordings of 15 Slovak speakers of English. The results suggest that Slovak speakers use glottalization extensively in their production of English. This should be taken into consideration when looking for better methods for teaching English pronunciation. Keywords: glottalization, prosodic structure, Slovak, English, foreign accent

Movement in connection with space, structure and sound of material in architecture Josip Plečnik
Palátová, Dana ; KODET, Jan (advisor) ; Čeňková, Jitka (referee)
Being inspired by architecture and using non-traditional space for new dance production is nowadays an increasingly popular feature. This thesis extends the research on the functionality and operation of space on building the choreography; it looks at this relationship especially through dance, which is based on these two concepts. In my choreographic works, I focus on this issue as could have been also proved in my previous thesis Scenography and space in choreography of Sasha Waltz from 2011.
When preparing chorographical and subsequently theoretical research for my diploma thesis, the procedures governing architects were practically applied to the movements. I observed the movement and creation process being influenced by my choreography. The work title also stresses out, except the space itself, the importance of texture, shape and sound materials in it that advance the creation of dance choreography. On this basis, I created choreographic principles which I analyze in detail also in my work.
This work is divided into four main chapters. The first chapter is devoted to the issue of connecting architecture and dancing, its historical development, the concept of site specific performances, to the choreographers who work with this theme and particularly dance in sacred space. The second chapter describes the creations and bibliography of architect Josip Plecnik. He constructed the church of the Sacred Heart by which I was initially inspired for my choreography. This architectonical treasure is in more details described in the third chapter. The last chapter as the final shape is represented by the choreography Materia which was created on the basis of the findings from previous chapters that means of the spaces of Plečnik's church. An integral part of this thesis is a DVD attached, showing the performance Materia, and embedded images which shall serve for better orientation and visual imagination to the topic.
The aim of this work is multiple: to point out the relationship between architecture and dance; to address the problems existing in contemporary dance due to its transfer into certain areas and propose possible solutions for avoiding that problem or using this issue for chorographical inspiration.
In this work, I use a compilation method based on an analysis of the basic sources and documents and I add my own texts and knowledge gained during the process of creating this production. This piece can also serve as a source for further research in the field of choreography.

Threat management for CERT/CSIRT teams
Machálek, Jiří ; Peterka, Jiří (advisor) ; Lukeš, Dan (referee)
The increasing importance of the Internet as an integral part of contemporary society has stressed the need to formalize the process of response to security incidents that accompany it inseparably. Security teams of the CERT/CSIRT type are established at different levels for this purpose. These teams respond to reports from their constituency and cooperate with other teams. This thesis introduces the reader to the issues these teams deal with and analyzes their needs in resolving threats and problems related to DNS and its domains. Part of the work is an overview of the basic existing tools to support the work of CERT/CSIRT teams to solve problems with domains, the design of a tool Malicious Domain Manager and description of its implementation. The results of test run of this tool by CZ.NIC-CSIRT team show its contribution to security of DNS.

Modelování portfoliového kreditního rizika
Kolman, Marek ; Witzany, Jiří (advisor) ; Stádník, Bohumil (referee)
Thesis Portfolio Credit Risk Modeling focuses on state-of-the-art credit models largely implemented by banks into their banking risk-assessment and complementary valuation system frameworks. Reader is provided in general with both theoretical and applied (practical) approaches that are giving a clear notion how selected portfolio models perform in real-world environment. Our study comprises CreditMetrics, CreditRisk+ and KMV model. In the first part of the thesis, our intention is to clarify theoretically main features, modeling principles and moreover we also suggest hypotheses about strengths/drawbacks of every scrutinized model. Subsequently, in the applied part we test the models in a lab-environment but with real-world market data. Noticeable stress is also put on model calibration. This enables us to con firm/reject the assumptions we made in the theoretical part. In the very end there follows a straightforward general overview of all outputs and a conclusion.

Cytoplasmic membrane of Bacillus subtilis Regulation of the physical parameters
Beranová, Jana ; Konopásek, Ivo (advisor) ; Branny, Pavel (referee) ; Holoubek, Aleš (referee)
Bacillus subtilis, a model Gram-positive soil bacterium, employs two distinct mechanisms in its membrane adaptation to low temperature: 1) Long-term adaptation to suboptimal temperature is accomplished by increasing the ratio of anteiso- to iso-branched fatty acids in the membrane lipids. 2) After a sudden temperature decrease, the oxygen-dependent fatty acid desaturase (Des) is induced which desaturates fatty-acyl chains incorporated in membrane lipids. The transcription of the gene encoding desaturase, des, is activated by the decrease of the membrane order, via two- component system DesK-DesR. In this work, I studied the influence of cultivation conditions on the mechanisms of B. subtilis membrane adjustments for a low temperature employing fatty acid analysis, fluorescence spectroscopy, differential scanning calorimetry and methods of molecular biology. In the first part of this work, I examined the impact of the cultivation medium on the composition and biophysical features of the B. subtilis cytoplasmic membrane during growth under the optimal (40 řC) and suboptimal (20 řC) cultivation temperature. I compared the nutrient-rich complex medium containing glucose and the mineral medium supplemented with either glucose or glycerol. The results obtained showed the crucial importance of medium...

The Landscape of the Czech-Austrian Borderland: Development and Heritage
Rašín, Robin
The presented study is an example of the research of trans-boundary landscapes underwent in the exemplary area of the Czech-Austrian borderland. In the focus of the research was the history-geographical analysis of landscapes' macro- and microstructure. The research had two main objections. Firstly, we tried to identify shared/different features of the Czech and Austrian landscapes development during the era of politically sharply divided Europe. Secondly, we paid attention to stabile landscape features. The proposed procedure of identification of stabile landscape features can be used as a basis for humanistic orientated landscape research. In order to answer the research questions, we used data of several sources - statistical evidence, historical maps, aerial photographs. The data were analyzed and evaluated by previously published as well as newly developed indexes. The results show that the development of landscape macrostructure was very similar on both Czech and Austrian side of the borderland - e.g. land use structure and its development over the selected time period. However, the research of the landscape microstructure provided a proof of different landscape formation when compared Czech and Austrian borderland - e.g. arable land areal index. The study pointed out the obvious need for a...

Molecular variability and distribution of the Frustulia rhomboides species complex (Bacillariophyceae)
Urbánková, Pavla ; Kulichová, Jana (advisor) ; Bešta, Tomáš (referee)
Recent use of molecular methods to revisit taxonomically problematic diatom species revealed severe limitations of morphological species concept. Characterization of diatom species which was based solely on the morphology of their frustules often generated too broad species boundaries which inevitably lead to wrong conclusions about their ecology and distribution. Widespread opinion that many diatom species are cosmopolitan generalists resulted in a theory that dispersal of diatoms is not limited by geographical distance. However, a number of recent studies showed that dispersal of diatoms is governed by the same rules which matter for macroorganisms. Proposed master thesis addresses the topic of diversity and dispersal in diatom species complex Frustulia rhomboides sensu lato in Europe and New Zealand. Results suggest that: (1) although revealed molecular variability in this complex shows clear ecological and biogeographical signal, it is not correlated in morphology. This is another support to general need for adoption of different species concept in diatoms. (2) A considerably uneven ratio in species diversity of genus Frustulia found in ecological similar habitats in Europe and New Zealand supports the idea that diatom dispersal is limited and stressed the need for studies dealing with biogeography.

Towards an Eco-inspired poetics of minimalist narrative
Kuzmičová, Anežka ; Pokorný, Martin (referee) ; Bílek, Petr (advisor)
What is a minimalist narrative, and what are its characteristic features? How do you identify one? For many critics, minimalist writing is a strictly historical notion - even though they at the same time, like John Barth does in his famous apologetics "A Few Words About Minimalism", paradoxically enough stress its ubiquitous nature throughout literature of all times. By narrative minimalism the American critic generally means the austere style of the novels and short stories of Raymond Carver, Amy Hempel, Mary Robison, Joan Didion, Ann Beattie. An American literary current of the 1970s mainly, devoted merely to the quotidian, descriptive, often reduced to what can be perceived from the outside of a human character. Thereby: the "dirty realism" or "K-mart realism". These derogatory labels tell us that the literary reviewer and critic of today still formulates his terms and judgments out of a hierarchically ordered, traditional presupposition of what a narrative text is and should be, working with a virtual model of balance between "form" and "content". Translated into the language of classical narratology: story discourse.

Znamenáčková, Radka ; Truc, Michal (advisor) ; Ježková, Martina (referee)
This diploma thesis brings together findings concerning the problematic of postsurgical active scars putting the stress on postsurgical abdominal scars. It deals with a patofysiology of active scars. First part summarizes case studies concerning diagnostic, manual treatment of active scar tissue and clinical importance of active scars. Second one presents examination of after-hysterectomy patients. Results suggest that active abdominal scar can disturb locomotor system function. In fact it can cause locomotor dysfunction and may contribute to painful conditions of the locomotor system. Powered by TCPDF (www.tcpdf.org)
