The Image Analyses Utilization at Nickel-base Superalloy Degradation Classification

V provozních podmínkách spalovacích turbín proudových motorů jsou lopatky oběžných kol namáhány časově, teplotně a napěťově proměnnými cykly zatěžování. Během provozu jsou lopatky vystaveny řadě degradačních vlivů, zejména vysokoteplotní korozi, únavovým procesům a creepu. Předložená práce se zabývá studiem struktury lité superslitiny INCONEL 713 LC, podrobené creepovým zkouškám. Strukturní změny (degradace) byly hodnoceny s pomocí obrazové analýzy. Creepovými zkouškami niklové superslitiny Inconel 713 LC při konstantním zatížení v rozsahu teplot 750 až 950°C byly modelovány provozní podmínky žárových částí, používaných v plynových turbinách a turbokompresorech. Po lomu zkušebních tyčí byly metodami světelné a elektronové mikroskopie a obrazové analýzy analyzovány změny ve struktuře v závislosti na době, teplotě a aplikovaném napětí.During operational conditions of internal combustion turbines of turbojet engines, the impeller blades are stressed by load cycles which vary in time, temperature and stress. In the course of operation, the blades are exposed to a considerable number of degradation effects, particularly high-temperature corrosion, fatigue processes and creep. The presented work is aimed at the study of the structure cast nickel-base superalloy INCONEL 713 LC, creep tests exposured. The structural changes (degradation) was clasifikation by the help of image analyses. Operational conditions of heat parts, used in gas turbines and turbo-compressors, were simulated by creep tests of Inconel 713 LC nickel superalloy during a constant load of temperatures ranging from 750 up to 950C. Changes in the structure dependent upon time, temperature and stress applied were analysed by means of light and electron microscopy methods and image analyses after the fracture of test bars.

Floristická výzdoba historického interiéru

The subject matter of this work is the history of Dušan Jurkovič's villa, its contemporary use and the use of flowers therein throughout history. Furthermore, the thesis deals with different techniques used in floristry and styles of floral design in historical interiors, as well as different assortments as they were used at the turn of the 20th century. The practical part deals with the floral designs used for Dušan Jurkovič's villa; they consist of 12 different arrangements that complement both the interior and the exterior of the building

Strategic Development of Municipalities up to 2000 Inhabitants

The aim of my bachelor thesis is to examine the process of preparation of a strategic development plan in selected municipalities up to 2000 inhabitants. I chose the municipalities Hosín, Hořice na Šumavě and Albrechtice nad Vltavou.The theoretical part contains a search of professional literature in the field of strategic planning in public administration. The practical part contains an analysis of strategic documents of selected municipalities. A questionnaire survey was conducted among the mayors of selected municipalities to obtain information about the process of creation of the strategic document. Based on the answers from the questionnaire, a semi-structured interview was conducted with each mayor. The creation of a strategic document of each of the municipalities is evaluated and possible actions are proposed.Cílem mé bakalářské práce je zmapování tvorby strategického plánu rozvoje ve vybraných obcích do 2000 obyvatel. Zvolila jsem obce Hosín, Hořice na Šumavě a Albrechtice nad Vltavou. V teoretické části je obsažena rešerše odborné literatury v oblasti strategického plánování ve veřejné správě. V praktické části je analýza strategických dokumentů vybraných obcí. Pro získání informací o tvorbě strategického dokumentu bylo provedeno dotazníkové šetření mezi starosty vybraných obcí. Na základě odpovědí z dotazníku byl s každým starostou veden polostrukturovaný rozhovor. Tvorba strategického dokumentu každé z obcí je vyhodnocena a je navrženo možné opatření

Barn and Tempel. German Churches in North Bohemia around the Year of 1900

Although the North Bohemian region is mainly associated with the industrial rise of the second half of the nineteenth century, which altered the local scenery and cities irreversibly, there were also far more traditional constructions being built around 1900, such churches. Between their solid-state and period concept is blended the influence of the authentic architectural progression, individual impress of architects, furthermore liturgical requirements of particular beliefs and concrete visions of owner-builders. Back then the ideal image of a church was seen as the root of discussion and polemic when many theoretical texts and building regulations were originated. The submitted work observes mainly the use of modern architectonic components following authentically traditional church architecture type. It is done pre-eminently, based on written theory and architectural practices confrontation. The given discussion I pursue with Catholics, Old-Catholics and mainly with Evangelical Confessions, whose base of theoretical text is the widest and newly build churches the most numerous. The subject given is closely related to national questions, situation and purpose of the German inhabitants resided in the territory of North Bohemia. As well as to fundamental influences that were coming here from neighboring..

Sacral architecture of Max Kühn and Heinrich Fanta in Liberec

The subject of this thesis ist work of Max Kühn and Heirich Fanta, who belonged to the most influential architects in the first decades of 20 th century in Liberec. These two authors created a wide range of building types, but the main interest of this thesis is concentrated on their three churches, that were builded in Liberec in a short time span between years 1906 and 1911. Attention is paid to historical foundations of these buildings and to their original and present architectural form and decoration. Analyzed are used materials and technologies as well as artistic styles, which influenced construction and esthetic form of the churches. Disscused is also contemporary architectural background, inspiration and possible influence of theory, important personalities and critics, that may have lead the work of Max Kühn and Heinrich Fanta in a specific direction

Relationships of Siblings of Children of the Same Age with Combined Disability

My bachelor thesis deals with the relationships of siblings of children of the same age with combined disability. These relations are extremely important, they help socialise and form the identity of every individual. They help us realise ourselves , our social class we belong to, our own self-confidence and self-realisation. My bachelor thesis describes attitudes and relations of the people of the same age and the society towards the disabled people, and the characteristics of the combined disability and its possible combinations. The life of the family with a disabled child, the position of healthy siblings and the communication between the parents and their disabled children and the healthy ones. Specific siblings relationship and the influence of disabled children on the healthy ones. Besides this the thesis talks about the relations between the children of the same age, creation of them and common socialisation. The peer groups, the creations and maintenance of peer relationships of the siblings with combined disability, the influence of a disabled sibling on healthy peers and particularly the perception of own peer relationship of the healthy siblings. The research is done via quality method with help of a semi-structured interview. The aim of the bachelor thesis is to answer the question: Can a..
