This master thesis shortly deals with properties and usage of the Resysta material. The main objective of this thesis is to determine a temperature influence on tensile strength of welded and glued joints made from the material Resysta, for an usage such as an outdoor furniture, temperature influence analysis of the joints and to present the results of the analysis obtained by measurements. Further objectives are: tensile strength experiment of material Resysta and to determine influence of placing the pieces in a desk in different directions. Results will serve as a basis for a specific firm; as a basis for deciding between technology of gluing and a technology of welding and also for input for a custom made single purpose machine made for welding of material Resysta. Tests were performed in exposure temperatures -30 °C, 20 °C and 60 °C. We will perform two tests; first test will focus on the tensile strength of glued and welded joints and second one will try to test of tensile strength of Resysta material. Experiments were conducted according to standards ČSN EN 205 and ISO 527-1 on the Instron 3365 testing machine. Laboratory tests showed that values of tensile strength were decreased while increasing the exposure temperature and this was consistent in every test performed. A statistical significance was also confirmed in work piece direction influence on a board. There were higher values of the tensile strength in longitudinal direction than in the transverse.

This dissertation is devoted to the topic of Child{\crq}s hero in an extreme situation inspired predominantly by the Czech literature of the 1950{\crq}s and 1960{\crq}s. The essential material for my work was works of the following Czech authors: Arnošt Lustig, Karol Sidon, Josef Fuks, Jan Otčenášek, Ludvík Aškenazy a J.R.Pick. Besides them I also used books by the French writer Romain Rolland which I compared to the Czech works. The dissertation is divided into two parts. In the first part I devote myself to the concept of extreme situation itself. I try to define this concept from the point of view of psychology as well as to show its concrete manifestation in individual works. The second part deals with interpretations of the works in the framework of which I explore the issue of an extreme situation.

Particulate matter (PM) air pollution is one of the most important topics in the field of environmental protection, and coal strip mining is a significant source of coarse atmospheric aerosol. In order to implement appropriate regulations to improve air quality, we need to identify the major sources of pollution. PM is usually measured in a ground-based manner and its dispersion is only modelled. Therefore, the objective of this study was to measure concentrations of coarse aerosol in the atmospheric boundary layer above the area of the coal strip mine through experimental airborne measurements and to estimate pollution contribution of mining to the surroundings. Measurements were carried out from November 11 to November 26, 2012, at Vršany coal mine, Czech Republic. An electrically powered airship was used with a specially designed gondola carrying aerosol monitors DustTrak DRX and P-Trak. Temperature and relative humidity data were also recorded. Repeated flights were performed at several heights above mine edge level. PM1-10 and GPS data were recorded every second. Average airship velocity ranged from 6 to 7 ms-1 . Flight measurements were also compared to ground-based measurements of PM10 and meteorological data. Weather during our measurements was characterised by low temperatures, high relative...

This master's thesis deals with pulsating flow of Newtonian and non-Newtonian fluid. Theoretical part represents necessary theoretical knowledge for pulsating flow and understanding of non-Newtonian behaviour. Furthermore the thesis focus is directed on numerical simulation of pulsating flow in straight, ideally rigid tube and in patient-specific model of human artery, more precisely in carotid. Two methods are used: numerical solution based on finite volume method (FVM) and also analytical solution using Bessel functions by Womersley. Results are validated against experimental measurements of velocity profiles by particle image velocity method (PIV). The agreement between numerical and experimental data with consideration of PIV inaccuracy was was very good from both point of views - qualitative and quantitative. Numerical solution also compare influence of turbulence and non-Newtonian behaviour towards base (laminar flow, Newtonian fluid). Developed methodology is then applied on patient-specific model of carotid, which was renovated from computed tomography. Measurements in vivo in human arteries is very expensive and often invasive. Because of that measurement outputs are limited, most of the time on pressure and flow. Computational fluid dynamics (CFD) is non-invasive and outputs are through whole domain. Due to these advantages CFD significantly contributes to understanding of hemodynamics influence in cardiovascular diseases.

Curves of resistance is different for each electric appliance, and depending on the size and over-voltage network, the burden on resources and voltage during the event.. The goal of this work is to devise a methodology for measuring the implementation of parametric measurement limit curves of resistance for selected types of appliances.

Diploma thesis describes the design of main structure reinforcement of the railway bridge ,,Gagarin’’ in the 5,872 km of route Český Těšín – Ostrava Kunčice. Reinforcement is achieved by combination of composite slab-shaped channel with the continuous gravel ballast and free additional prestressing cables. There are 3 variants for which the design and assessment of main structure is performed. Evaluation of the options is performed on basis of calculations. There are made additional calculations and drawings for best variant.

The master thesis consists of a theoretical part and a practical part. In the theoretical part jet-grouting technology is described briefly. Mechanical properties of jet-grouted piles were characterized. Various estimation methods of ultimate pile bearing capacity are described in this thesis – analytical calculation of ultimate bearing capacity for bored piles and estimation of ultimate pile bearing capacity by analysis of load-displacement curve defined by CHIN (1970; 1972). Load transfer method for piles and hyperbolic load-transfer curve are introduced. As a part of the load-trasfer method analysis, a method of estimating ultimate pile shaft friction called beta method is defined. In the practical part were evaluated several static load tests of jet-grouted piles and were constructed their load-displacemnt curves. Then reverse analysis of the results from static load tests was performed using load-transfer method. Then ultimate pile bearing capacity was estimated using analytical calculation of pile bearing capacity for bored piles and using analysis of load-displacement curve with method by CHIN (1970; 1972). By evaluation of load transfer method and beta method ultimate shaft resistence for each pile was estimated. Results and load-displacement curves were compared.

This thesis deals with stress, strain and reliability analysis of synchronous generator stator including an inhomogeneous temperature field. Using the finite element method, stress and strain are calculated, and from these values safety against yield strength is determined, which is followed by the life calculation of the most stressed weld joint and the determination of its possible damage during the period required by the customer.

The diploma thesis describes design and assessment of foundation of tall building. Existing reinforced concrete slab-pile foundation structure was assessed as unsatisfactory at the ultimate limit state. Design of two new options was processed: slab-pile foundation with adjusted slab thickness and slab foundation without piles. Both options were assessed at the ultimate limit state and the serviceability limit state. Foundation options were designed as water-impermeable structure of white tank and meet requirements for this type of structures.
