Energy efficient house

Předmětem bakalářské práce je zpracování projektové dokumentace pro novostavbu energeticky efektivního rodinného domu. Novostavba se nachází ve Šternberku. Objekt je navržen jako dvoupodlažní částečně podsklepený ve tvaru obdélníku. Dům je zastřešen sedlovou střechou a přilehlá garáž pultovou střechou. Fasáda domu je bílé barvy s dekorativními prvky kamenného obkladu. Jedná se o budovu z keramických tvárnic, suterén je ze ztraceného bednění.The topic of this bachelor thesis is processing of a project documentation of a new Energy efficient family house. The new family house is located in Šternberk. The object is designed as two-floor house, partly with a cellar in the rectangular shape. The house is covered with a grable roof and a garage next to the house with a mono-pitched roof. Facade of house is white with decorative of elements stone veneer. The construction is made from ceramic blocks and basement is made from permanent formwork.

Exploring and explaining participation in local opposition: brown coal mining in Horní Jiřetín

This book summarizes a three-year research project on local opposition to coal mining in the Northwestern part of the Czech Republic. The research focused on the relational dimensions of the opposition movement and the political context in which the movement operates

What's next for the European coal heartland? Exploring the future of coal as presented in German, Polish and Czech press

This article addresses the future of coal in the European coal heartland, i.e. in the area of Germany, Poland and the Czech Republic, which together account for nearly 57% of coal consumption and 87% of coal-mining jobs in the EU. It approaches the problem within the interpretative tradition of social research and explores the coverage of the future of coal in major newspapers and political magazines in the three countries. The results show that despite similar material conditions, the issue is presented in a fundamentally different manner as the media tend follow the dominant energy policy paradigm in their countries: in Germany, they facilitate the phase-out policies; in Poland, they act as an inhibiting factor; while in the Czech Republic, their coverage echoes the political uncertainty around lignite mining in the northwest part of the country. The results also suggest that the media act mainly as a platform for the countries’ decision makers and energy policy stakeholders to voice their perspectives. The prevalent media coverage thus simultaneously enable and constrain policy options by promoting dominant discourses and preventing alternative views from surfacing

Cutting Force When Machining Hardened Steel and the Surface Roughness Achieved

This article deals primarily with the problem of determining the cutting force when machining hardened steels. For this study, the steel used was 100 Cr6, number 1.3505. The secondary aspects of the study focused on the evaluation of the surface quality of machined samples and the recommendation of cutting conditions. A wide variety of components are used in engineering, the final heat treatment of which is hardening. These components are usually critical in a particular product. The quality of these components determines the correct functioning of the entire body of technical equipment, and ultimately, its service life. In our study, these are the core parts of thrust bearings, specifically the rolling elements. The subject of this experiment involves machining these components in the hardened state with cubic boron nitride tools and the continuous measurement of the cutting force using a dynamometer. The machining is carried out on a conventional lathe. A total of 12 combinations of cutting conditions were set. Specifically, for three cutting speeds of 130, 155 and 180 m·min1, the feed rates of 0.05 and 0.1 mm·rev1 and the cutting widths of 0.2 and 0.35 mm, were evaluated The evaluation assessed the surface quality by both touch and non-touch methods. A structural equation with the appropriate constants and exponents was then constructed from the data obtained using the dynamometer. The experiment confirmed the potential of achieving a value of the average arithmetic profile deviation Ra in the range of 0.3–0.4 when turning hardened steels with cubic boron nitride

Mixed-use building

Předmětem této diplomové práce projektová dokumentace novostavby polyfunkčního domu v proluce v Brně na ulici Křenová. Objekt má čtyři nadzemní a jedno podzemní podlaží. V prvním nadzemním podlaží se nachází provozovny, konkrétně kadeřnictví a lékárna, s administrativním provozem v podobě menší kanceláře. Celé druhé nadzemní podlaží tvoří kanceláře-menší a větší ( v případě potřeby se může spojit v jednu velkou kancelář dělenou na dvě části. Ve třetím a čtvrtém nadzemním podlaží jsou pak jednotlivé byty. Celkem se zde nachází 2 byty 4+kk, 2 byty 2+kk, 4 garsonky 1+kk a 2 bezbariérové byty 1+kk. Pro jednotlivé byty se na podlažích nachází sklepní kóje. V podzemním podlaží je pak umístěno zázemí pro fungování objektu, kóje, sušárna, kolárna a sklady kanceláří. Na severní straně parcely je umístěno pro tento objekt nadzemní parkoviště. Díky průchodnosti polyfunkčního domu ze severní na jižní stranu (a naopak) nemusí budoucí uživatelé zdlouhavě obcházet blok.The subject of the this thesis is newly built mixed-use building in gap site in the Brno on the Křenová street. The object will have four aboveground floors and one underground floor. First floor there are officers, specifically hairdresser, pharmacy and establishement of small office. The whole second floor consists of smaller and bigger offices (if it be necessary, it can be connected in one large office divided into two parts). On the third and fourth aboveground floor there are individually flats. There are two flats 4+kitchen, two flats 2+kitchen, four single flats with kitchen and two barrier-free flats. For these flats, there are basement cellar floor. In the underground floor, there are single cellars in the basement for single-room flats, basement for the operation of the building, a cubicle, a drying room, a bicycle room and office storage. There is an overground parking on the northern side of the object. Thanks to the passage of the building from the north to the south side saves your steps.
