The goal of the Master thesis is to design a grain container. The thesis involves a possible method of grain storage depending on the quality and condition of the grain and also the ways of filling and emptying the container with all the problems that might occur. The thesis deals for example with a possibility of occurrence of vault and with it associated change of state of stress, or with the pressure surges in the container. The thesis involves an analysis of an appropriate construction solution, a design of the main dimensions of the container and a test calculation of the container ´s strength.

This thesis focuses on the verification of physical and mechanical characteristics of hardened concrete, especially concrete compressive strength, static and dynamic modulus of elasticity. The job description is to perform a series of laboratory analyzes for structural concrete and evaluate the test results meet requirements that are specified in the European standards for designing buildings. The work also includes selected techniques for risk assessment (FMEA, Pareto diagram, Ishikawa diagram) and their application to selected process. Part of the work is also a static comparison of measured characteristics and consideration of the risks associated with variations in the monitored quantities.

The dissertation is concerned about, according to author still “live” problem of optimization of logistic flow, with scope to company environment. The aim is to find correct methodology for defined problem and to apply it to particular case study. Theoretical part begins with description and analysis of actual state of problematic of logistic flow optimization and listing the methods which are able to be applied to these problems. The three main groups – exact methods, heuristic methods and combined methods take part in. The analysis continues further with searching the methods, useful for application in production company environment. Vast focus is on layout design task, because once layout is created, except some minor changes, it lasts usually for some years and therefore it is necessary to consider it properly. Moreover, there is also difference between other characteristics of production, as production planning and machines / technologies upgrade and layout; the former are in a certain manner changeable and not stable, but the layout cannot be changed on for ex. weekly basis. Contribution to research is located at the end of theoretical part, which is newly modified methodology to be more suitable for practical application. Practical part begins with the description of particular case study, e.g. actual status of logistic system in enterprise. The processes described include purchasing management, production management and mainly layout design of production space. The application of suitable methods consists of group technology methods – already known method, plus newly modified method and their mutual comparison. In addition is included already known value stream mapping method. The result is recommendation for change in layout design, developed by integration of results, brought by group technology methods and value stream mapping method.

The aim of the thesis is to elaborate the technological project for non-rotary (plate) parts production based on requirements of TOS KUŘIM – OS, a.s. The literary studies from the area of machining technology and technological designing are in the first part of the thesis. The evaluation of the contemporary state of production and dividing of products into groups is made in the next part. The following part of the thesis is dealing with the design and analysis of designed variants of disposition, choosing the most suitable variant, its optimalization and evaluation by the help of capacitive calculation. The drawing documentation (material flow included) and technoeconomic evaluation is elaborated in the final part of the thesis.

The submitted diploma thesis is focused on problematic of a radial expanding of tubes. In the first part of thesis, there is a summary of possible theoretical formulas for determining the stress-strain material parameters for biaxial bulging test of tube by liquid. Also there are showed several options for testing tools used in research abroad. The work also contains technological and control calculations for the selected test sample from the tube of steel 17 240 (1.4301). At the end of thesis, there are key points for tool design and there is also presented the proposed the test tool for a radial expanding of test sample of tube to the free space and with firmly fixed the ends of tube in the tool.

The presented diploma thesis deals with an innovative material test, so called Small Punch Test. There are main principles, advantages and limitations of the test stated in the thesis. There are stated also correlation procedures in order to obtain standard mechanical properties. A test fixture design has been done in order to perform test procedures at temperature range from 80 to 25 °C. Twelve experimental curves have been obtained from the test and typical quantities have been evaluated. The different accuracy of correlations with standard mechanical properties has been obtained using different correlation equations.

The aim of the thesis is the process of building technological project LIWA manufacturing facility in Pelhřimov. It deals mainly a technological process for the realization of the main building. The thesis contains a technical report, technological specification, control and test plan. Other parts of the work are time and financial plan, machine and mechanic design, project about equipment of construction site and time schedule. The annexes are further addressed drawings of the building site equipment.

The presented diploma thesis was elaborated as an architectural study of a Central European Forum in Olomouc (SEFO). Campus SEFO will be created as an reconstruction of the Museum of Modern Art (MUO) in Denis street and building in a neighboring vacant lot. The proposal involves urban, architectural, operational layout, design and material solutions objects in spatial context. Within SEFO and MUO they are created each operation - stand-alone units. Objects SEFO and MUO are interconnected. It is necessary to respect the separation of publicly accessible areas of compartments accessible only by employees. Architectural study includes space for exhibitions, library, multi-purpose space with facilities, vestibule usable for exhibition openings and other cultural activities, chamber music performances, as well as facilities for education, technological facilities of the building, the depositary (transport and central), photo studio restoration studio, office space, locker rooms and restrooms personnel. SEFO specific aim of capturing the diverse manifestations of visual culture of Central Europe after World War 2, the building's permanent exhibition, acquisition activity, temporary exhibitions, including larger medium-shows (eg. The biennial or triennial), discussion forums and other supporting cultural events.

This thesis solves the construction technology project extension at Three Steeples in Střítež, building apartments. Work includes the complete study of the implementation, including timing and the financial plan, assessment of the wider relations of transport routes, the project site equipment, design of the main building machines and mechanisms, technological specifications for masonry, inspection and test quality plan for walling, technological prescription for clay plasters and itemized budget rough construction of the main building.

This diploma thesis presents available FRP software for calculating load bearing capacity of the structures reinforced with FRP and compares them between each other. Furthermore theory and algorithm of my own software is presented here. Load bearing capacity of structures which are reinforced with non-metallic reinforcement and loaded by combination of normal force and bending moment can be solved by my programme. Effects of high temperatures on the concrete structures can be included in the calculation. In the second part of the thesis is calculated load-bearing capacity and deflection of the real beam reinforced with FRP reinforcement and load-bearing capacity of member with FRP reinforcement with effect of elevated temperature. This has been done using my software. Comparison of results from hand calculation and laboratory load-bearing testing is done at the end. This laboratory testing was accomplished by Institute of Concrete and Mansory Structures at our faculty.
