Přírodní domy v zahradách / Natural houses in gardens

Poláčková, Kristýna January 2017 (has links)
This thesis solves general nature houses in the gardens and the purpose and principle of the garden, its function and composition. After a search of the following project. This project is designed based on analyzes of land area wider relations, claims on clients' needs (whole family) and at its own discretion. The project is based on a proposal by the object (timber), which is taken from a construction company and a further proposal designed garden composition. When projecting gardens are mainly used natural materials, the creation of flower beds are used and extensively perennial plantings, part of the garden is also part of the economic and compost.

Revitalizace plochy zeleně Praha Libuš při ulici Brunelova / Revitalisation of the landscape part of Prague 4 along the Brunelova street

Kosinková, Martina January 2016 (has links)
This thesis deals with the revitalization of public green spaces in the City of Prague Libuš. The aim was to propose appropriate solutions with regard to the close communications, a private school and a rehabilitation center and create a safe and recreational space that would improve living conditions for the inhabitants of the large housing estate settlement in Libuš. It was necessary to analyze the region in terms of natural conditions, broader relations and infrastructure before the proposal. The analysis of the current state was conducted, including the inventory of the trees and field survey. Furthermore, based on the questionnaire survey conducted, the locals, students and teachers from the private school nearby expressed their views on the given territory. It has been found, thanks to the method Time-Lapse Photography Study, which parts of the territory people frequently move in and that was also reflected in the design of the area. The evaluation of the main tendencies of current and future development of the territory and the mutual comparison of the strengths and weaknesses of the area with the potential opportunities and threats are made in the SWOT analysis. A proposal, that would increase the interest of the locals in the area, was created on the basis of the results of analyzes conducted. Since it is a very rundown area, there must be a significant reduction in the number of seeding trees, removing stumps and building rubble. The functionality of insulating greenery and the natural character of the area must be maintained simultaneously. There will be an overall increase in the attractiveness and safety of the territory thanks to the revitalization of greenery, building of road networks, the placement of furniture and other technical elements. The area would not deserve only to shorten the route, but it might be used for short-term recreation by the visitors.

Vývoj a výzkum environmentálně úsporných izolačních materiálů / Development of environmental friendly materials

Peterková, Jitka January 2013 (has links)
Increasing demand for new progressive construction materials requires development of modern environmentally friendly materials with excellent end-use properties and reasonable price. One of the main objectives of material research in building industry is using renewable resources of raw materials of industrial waste for development of new construction materials. Current trend of thermal insulation of building constructions results in development of environmentally friendly insulation materials based on renewable material resources from agriculture and stock farming, which could became alternative for current common use insulation materials in the future. The thesis describes research and development of insulation materials based on natural fibres of agricultural origin; in particular fibres of hemp, flax and jute. Hydrothermal behavior of developed materials is studied including computational simulation of behavior of researched materials after building in the construction.

Problematika zaměřování poruch na kabelech / The issue of fault location on cables

VOKÁLEK, Petr January 2014 (has links)
This work is focused on the locating of faults of the cables laid in the ground. Firstly it describes particular types of cables and their basic physical characteristics. Following part deals with widely used methods for locating cable faults including their comparison. Than it describes DC measurements which are used to identify the type of fault. In the practical part there is a complete DC measurement on the specific cable and finding out the limits of usefulness regarding to the chosen methods for locating the failures.

Použití exotermických nálitků u odlitků ze slitin hliníku / Use of exothermic sleeves for aluminium alloy castings

Jakubec, Petr January 2017 (has links)
This master's thesis deals with the influence of the exothermic riser sleeves on the solidification time of aluminum alloys. The thesis is divided into five parts. The first chapter describes solidification of cast alloys. The second chapter deals with the designing of risers. The third chapter is focused on the types of risers. The fourth chapter describes ways of intensification of risers and chemical composition of exothermic and insulating mixtures for production of riser sleeves. The main fifth chapter focuses on experimental measurements of temperatures and solidification time of aluminum alloy in castings, risers and exothermic and insulating riser sleeves.

Anorganický tepelněizolační materiál pro zdící prvky / Inorganic thermal insulation material for masonry elements

Sedlačík, Martin January 2020 (has links)
This master’s thesis deals with preparation of foam glass and explores the possibilies of utilization of this material as an inorganic thermal insulating filler of fired hollow bricks. Foam glass was prepared via powder sintering method from waste packaging glass, using limestone and graphite as foaming agents. After inital analysis of raw materials, the effect of mixture composition and different processing parameters on bulk density, pore size and morphology of foam glass was investigated. Last but not least, different ways of manufacturing thermal insulating bricks, by preparation of foam glass directly in the cavities of fired hollow bricks, were tested.

Přenos tepla v žárovzdorném vyložení tepelných agregátů / Transport of heat in refractory materials

Pařízek, Ladislav January 2013 (has links)
The focus of my master’s thesis is a preparation of refractory insulating material made by foaming method. In the theoretic part are described properties of refractory materials especially thermal properties, classification of refractory materials and description of insulating refractory materials production. The experimental part of thesis focus firstly on problem solving during production process of material, characterization of materials with instrumentals method (SEM, XRD and TG-DTA-EGA) and examination of heat transfer in constructed equipment.
