Natural houses in gardens
Formánková, Kristýna ; Kunt, Miroslav (advisor)
Thesis discusses natural houses which are supposed to be part of our lives in the future. These houses may be for someone and they might prefer smarter building with non-recyclable materials when choosing a new housing. But it is necessary to think about our future and sustainable development. We also need to tell ourselves what is really a priority for our planet. There comes a time when they will prefer building materials which can be used somehow after some time or be recycled. This is related to the design of the garden. It is designed to fulfil an ornamental, economic and social function. The garden is an integral part of each house, therefore it is important for each element used to be creating the garden as a linked harmonious whole. The study deals with the concept of a natural houses home in accordance with the maximum use of the garden.

Konopecká, Vladislava ; Janeček, Miloslav (advisor) ; Kalibová, Jana (referee)
The thesis is following up on the findings to the issues presented in the Bachelor's thesis, where they were described mainly the methods and materials used to secure the slopes of pipeline, will address not only the final solution method of protection against erosion of the slopes, but in particular all conditioning influences such as the topography, the type and quality of rock and soil in the area of the building, surrounding buildings, and last but not least property relations that can significantly affect the design solution in terms of difficulty of implementation, durability, aesthetics and economic performance of the resulting construction works. Alpha-Omega of the initial phase is the analysis and the interdependence of the issues just for land consolidation, anti-erosion measures, construction procedures in accordance with the geology of the chosen territory and the intended realization of the construction project. The evaluation of the risks associated with this issue on the basis of field investigation, examination with a valid legal legislation, SWOT analysis will be ended.

FRACTURE MECHANICS ASSESSMENT OF CRACKED WELDED POLYOLEFIN PIPES
Mikula, Jakub ; Ševčík, Martin ; Hutař, Pavel ; Náhlík, Luboš
The aim of this paper is to present methodology for estimation of fracture mechanics parameters in polyolefin pipes with an axially oriented crack using three dimensional numerical analyses. Linear elastic fracture mechanics is used for description of fracture behavior. In the paper, three different variants of pipe weld with an internal axial semi-elliptical crack are studied. Numerical models correspond to a cracked pipe containing material nonhomogeneity in the welding area caused by welding process. A critical locations of the crack initiated along the pipe wall is found and the stress intensity factor for such cracks with real crack shape are numerically estimated in these critical locations. The methodology presented here can be used for estimation of residual lifetime of welded polymer pipes containing crack.

Noise, Transport and Structural Properties of High Energy Radiation Detectors Based on CdTe
Šik, Ondřej ; Lazar, Josef (referee) ; Navrátil, Vladislav (referee) ; Grmela, Lubomír (advisor)
Poptávka ze strany vesmírného výzkumu, zdravotnictví a bezpečnostního průmyslu způsobila v posledních letech zvýšený zájem o vývoj materiálů pro detekci a zobrazování vysokoenergetického záření. CdTe a jeho slitina CdZnTe. jsou polovodiče umožnují detekci záření o energiích v rozsahu 10 keV až 500 keV. Šířka zakázaného pásma u CdTe / CdZnTe je 1.46 -1.6 eV, což umožňuje produkci krystalů o vysoké rezistivitě (10^10-10^11 cm), která je dostačující pro použití CdTe / CdZnTe při pokojové teplotě. V mé práci byly zkoumány detektory CdTe/CdZnTe v různých stádiích jejich poruchovosti. Byly použity velmi kvalitní spektroskopické detektory, materiál s nižší rezistivitou a výraznou polarizací, detektory s asymetrií elektrických parametrů kontaktů a teplotně degenerované vzorky. Z výsledků analýzy nízkofrekvenčního šumu je patrný obecný závěr, že zvýšená koncentrace defektů způsobí změnu povahy původně monotónního spektra typu 1/f na spektrum s výrazným vlivem generačně-rekombinačních procesů. Další výrazná vlastnost degenerovaných detektorů a detektorů nižší kvality je nárůst spektrální hustoty šumu typu 1/f se vzrůstajícím napájecím napětí se směrnicí výrazně vyšší než 2. Strukturální a chemické analýzy poukázaly, že teplotní generace detektorů způsobuje difuzi kovu použitého při kontaktování a stopových prvků hlouběji do objemu krystalu. Část mé práce je věnována modifikaci povrchu svazkem argonových iontů a jejímu vlivu na chemické složení a morfologii povrchu.

One-Sided Random Context Grammars
Zemek, Petr ; Černá, Ivana (referee) ; Doc. In.g Petr Sosík, Dr. (referee) ; Meduna, Alexandr (advisor)
Tato disertační práce zavádí jednostranné gramatiky s nahodilým kontextem jako řízené gramatiky založené na bezkontextových gramatikách. V těchto gramatikách je ke každému pravidlu přiřazena množina povolujících symbolů a množina zakazujících symbolů a množina pravidel je rozdělena na množinu levých pravidel s nahodilým kontextem a množinu pravých pravidel s nahodilým kontextem . Levým pravidlem s nahodilým kontextem lze přepsat neterminál pokud se všechny povolující symboly vyskytují vlevo od přepisovaného neterminálu a žádný zakazující symbol tam přítomen není. Pravé pravidlo s nahodilým kontextem lze aplikovat analogicky, ale ona kontrola na přítomnost a nepřítomnost symbolů je provedena doprava od přepisovaného neterminálu. Práce je rozdělena na tři části. První část uvádí motivaci za zavedením jednostranných gramatik s nahodilým kontextem a umisťuje materiál pokrytý v této práci do vědeckého kontextu. Poté dává přehled základů teorie formálních jazyků a některých méně známých oblastí, jejichž znalost je nutná pro pochopení studovaného tématu. Druhá část tvoří jádro práce. Formálně definuje jednostranné gramatiky s nahodilým kontextem a studuje je z mnoha pohledů. Mezi studovaná témata patří generativní síla, vztah k jiným typům gramatik, redukce, normální formy, nejlevější derivace, zobecněné a LL verze těchto gramatiky. Třetí část této práce zakončuje diskusi několika poznámkami. Mezi ně patří poznámky týkající se aplikovatelnosti zavedených gramatik v praxi, bibliografie a otevřených problémů.

Methodology of the Cooperation between the Director and Actor and Contermporary Theater Practice
Glogrová, Kateřina ; BURIAN, Jan (advisor) ; HRBEK, Daniel (referee)
The thesis deals with the cooperation between the director and actor during individual phases of the staging process as they appear in everyday theatre life. The indiviual phases of the staging process are supplemented by the author's own experience with managing the actors, which she gained especially in the course of her studies at the Drama Faculty of AMU. The second part of the thesis investigates the issues of inner truthfulness and the possibilities of its achievement within the production of a play. As a part of collecting the material for the thesis, the author conducted a research, which included interviews with three professional directors - Hana Burešová, Ladislav Smoček and Štěpán Pácl, whose methods of work are described. In the final part of the thesis the author states that it is difficult to draw general conclusions about the cooperation between the director and actor because it is always of subjective nature. The issue of inner truthfulness is similarly difficult to generalise. Due to the multiplicity of options, however, neither of them loses attractiveness for further research.

Specifications of nursering care of patiens with complications after direct SKG/PTCA
BLÁHOVÁ, Ilona
Abstract In the Czech Republic there is no doubt about the tendency of gradual increase in median life expectancy, which is significantly affected by the fact that mortality from cardiovascular diseases, especially from acute coronary syndromes, has been decreasing. Besides the provable effect of a healthy lifestyle, diet and, by all means, a quality and effective pharmacotherapy, a significant development in the field of interventional cardiology contributes to this accomplishment. The number of coronographies, coronary angioplasties and implanted stents have multiplied, and today the invasive coronarographic diagnostics and percutaneous myocardial revascularization belong to the the most common diagnostic and therapeutic methods in treatment of acute forms of ischemic heart diseases. An obvious prerequisite for such a rapid development in the field of intervention coronary angiography was the establishment of a sufficiently dense network of catheter laboratories and specialized facilities, which provide a highly professional and intensive care for patients. This thesis is focused on three basic objectives: ? To survey and characterize differences in nursing care concerning various complications in patients after SKG / PCI ? To survey bio / psycho / social impacts of complications after SKG / PCI on a patient ? To identify and summarize personal and material prerequisites and requirements to ensure quality nursing care for these complicated conditions The research was conducted by using a qualitative methodology. The methods used were observation, non-standardized interviews and medical and nursing records analyses. The research survey samples on which the investigation was focused were patients with the acute coronary syndrome hospitalized in the coronary care unit in the Cardio Center in České Budějovice, their family members and also the nursing staff providing the comprehensive nursing care. The outcomes of this survey were eleven descriptive case reports characterizing the occurrence of the most frequent complications in patients with ACS after SKG / PCI. To ensure clarity, each case study is complemented by a thought map with an account of the most important nursing interventions in the management of specific acute conditions. The paper also contains a framework analysis of bio / psycho / social impacts of complicated situations on patients. It is interesting to compare this matter from the perspective of nurses and patients, which is seen in correlation graphs. The section describing the organizational and personnel provision is introduced with the characteristics of the medical process and it also contains the list of medical personnel with their qualifications and the length of experience in the Coronary care unit in České Budějovice. Summarization of the instrumental medical equipment is also based on the analysis of previous cases and is accompanied by photographs of the equipment typical and indispensable for the care of patients in the Coronary care unit, which primarily has an informative and complementary character to get an integrated view of the Coronary care unit running and the nursing staff work.
