Vývoj nového samonosného zateplovacího systému s ohledem na dynamické namáhání / Development of a new self-supporting insulation system with respect to dynamic stress

Machala, David January 2014 (has links)
This diploma thesis deals with suggestion of self-supporting insulating system that can be used for objects which insulating is more or less complicated. In this thesis are theoretically processed information about insulation systems while focus is on their structure, composition and principle of operation. Further, there is theoretically designed self-supporting insulating system which is practically built after theoretically composed testing for finding its basic properties. The most appropriate process of realization is formulated at the end after evaluation of the individual tests.

Pedotransferové funkce pro odhad vlhkostních retenčních křivek středně těžkých půd jižní Moravy / Pedotransfer functions for estimation of moisture retention curves of medium-heavy soils of South Moravia

Gavlasová, Iva January 2014 (has links)
The most important characteristics of each soil is its hydro-physical properties, which include retention curve. Retention curve expresses the relationship between humidity and pressure head. It is course affected by many factors such as grain size and mineralogical composition, humus content, structure and bulk density of dry soil. This thesis deals with direct and indirect determination of one of the basic hydraulic characteristics of the soil, soil moisture retention curve. For laboratory determination of moisture retention curves were used for sand tank and pressure instruments. Measured body retention curves were optimized RETC program.For indirect determination of retention curves were used Pedotransfer function by Wösten et . al .(1998 ) , derived from the European soils and under HYPRES Šútora and Štekauerová (2000). As in the project Wösten et al . (1998), PTF were processed for arable land in the area. The accuracy of both models PTF was assessed by the correlation coefficient R and standard error RMSE. Simple models PTF provide estimates of retention curves with sufficient accuracy for practical use in the locality.

Porovnání technických vlastností a technologií pokládky lehkých stavebních hmot pro podlahové konstrukce / Comparison of technical characteristics and technology of laying light building materials for floor construction

Mikulica, Karel January 2015 (has links)
This graduation thesis is aimed to presentation heat isolation materials for the floor constructions. The experimental part is devoted physical - mechanical properties suggested very light concretes with the cement. The main part of the thesis is devoted to form of the transit and putting of the individual heat isolation materials. In the end are suggested structures of the floor constructions with the respect to their properties and price.

Vliv různých agrotechnologií na fyzikální kvalitu půdy ve vybraných lokalitách v Jihomoravském kraji / The effects of different agro-technologies on the soil physical quality in selected localities in the South Moravian Region

Bažantová, Adéla January 2017 (has links)
Farmland is being handled by various the tillage of soil especially for the correct course of soil processes, plant growth and development and of course profit. There are two types of the tillage of soil are their conventional (classical) which involves plowing and minimization tillage, where is excluded plowing. The last few decades, the development the tillage of soil focuses on minimization tillage. This includes loosing up small depth, soil conservation tillage and direct seeding. This thesis is aimed at impact of minimization tillage on selected physical and hydraulic properties of the soil. Sampling undisturbed soil samples was performed on the experimental plot Kozlany by Kopecky rollers (V = 100 cm3) from depth of 0 - 10 cm, during the year 2016. On this plot was used minimization tillage in the form loosing up small depth and direct seeding.

Studium chování vybraných hornin při působení vysokých teplot / Study of the behavior of selected rocks at high temperatures

Holanec, Aleš January 2022 (has links)
The diploma thesis deals with the observation and diagnostics of transformations that take place in stone slabs of different mineralogical composition during heating to high temperatures. The theoretical part of the thesis deals with a summary of available information about selected types of rocks. Furthermore, it presents findings from the experimental thermal loading of a granite sample. The principles and instruments of laboratory experimental methods that are used to judge the resistance of rocks are described in detail. In the experimental part, the testing methodology is proposed, the procedure of production of rock test specimens is described and the way in which the thermal loading of stone slabs took place is explained. The results of the experiments are shown in the tables and graphs. A comparison of individual tests and properties of selected samples and evaluation of the obtained results is performed.

Stavební průzkum a diagnostika železobetonové konstrukce / Survey and Diagnostics of Reinforced Concrete Structure

Richterová, Dominika January 2022 (has links)
The main theme of this diploma thesis is a building survey and diagnostics of a reinforced concrete construction. In the first, theoretical part the focus lies on a description of each method for testing constructions and their evaluation. The second, practical part focuses mainly on finding of material characteristics and reinforcement of particular parts of the construction. On basis of obtained information, the final part of this paper focuses on static assessment of chosen parts of the construction.

Hodnocení kvality/zdraví půdy v blízkosti obce Bohaté Málkovice / Assessment health/quality of the soil near the village Bohaté Málkovice

Suchá, Kateřina January 2019 (has links)
Diploma thesis evaluates quality and healthiness of the soil health located close to Bohate Malkovice focusing on changes in both physical and chemical characteristics of the soil in time. The theoretical part describes physical, chemical, and biological parameters of the soil. Selected physical parameters are structure, texture, determination of measured weight, bulk density of the soil, porosity, actual volumetric water content of the soil, aeration, saturated and unsaturated hydraulic conductivity, infiltration, and colour. Chosen chemical parameters are pH, carbonates, soil electrical conductivity, and humus content. Picked biological parameters are microbial biomass, respiration, nitrogen content, and weed infestation. The practical part analyses selected indicators of quality of the soil from the location of the experiment close to Bohate Malkovice. The area under evaluation has been treated using reduced tillage for long term. The practical part is based on the laboratory examination of disturbed and undisturbed soil samples taken between years 2016 and 2018. Based on outcome results we can evaluate the quality of the soil considering plants growth, development, and soil fertility.
