This Master’s thesis deals with flange joints. A suitably designed flange joint (FJ) construction and installation is necessary to ensure the reliability of piping systems and machinery where these joints are used. The thesis describes the procedures of their design and assessment in terms of tightness, strength and durability. It focuses on the stiffness calculation of all components of FJ – primarily the stiffness of flanges, bolts and seals. The main part of the work was to create a computational program by using the Python language to determine the appropriate preload force in the bolts. The program uses the procedures described in the ČSN EN 1591-1 standard. The thesis describes computational algorithms of this program, verification of the program and its use in the assessment of FJ on a specific technical work – pressure vessel with adjacent piping. Verification was performed by comparing the acting force to the seals obtained from the computational program and the stress-strain analysis using the finite element method (FEM), where the load model in this stress-strain analysis included the preload force obtained from the computational program. The application of the pressure vessel computational program consisted in determining the preload forces for all FJs of this assembly. The last part describes the assessment of the most loaded FJ. Again, stress-strain state was evaluated using FEM and FJ was assessed for tightness, strength and durability using the NTD A.S.I. standard.

This final thesis addresses the approach of standards and software for calculation of pressure vessels loaded by external pressure and a design of own calculation software, including a demonstration on chosen geometry. The approaches of standards and software are solved in the form of research. The practical part describes the developed software, selected technologies for development and results of the demonstration. The demonstration was carried out on two geometries and was successful.

This project includes a basic overview of concepts as is communication, data communication and distributed to systems. Further focuses on the technology use for remote data collection. Part is dedicated PLC technologies, which use systems for remote data collection. The thesis is also mentioned the concept of quality of electrical energy and standard ČSN EN 50160. The main part is focused on the design, implementation and measurement of the PLC network.

This thesis deals with bridging of a lowland valley and the creek Dolanský in the section Jánovce – Jablonov on the Slovak motorway D1. Four variants of the bridge have been developed. Subsequently prestressed single box gilder with large overhangs that are supported by precast struts was selected as the most suitable variant. The construction of the bridge will take place in a formwork suspended on overhead launching scaffolding. The static assessment according to the Europan standard has been drawn up for this variant. The load of the bridge is projected according to the ČSN EN 1991-2 - Traffic loads on bridges and the dimensoin of concrete structures according to the ČSN EN 1992-2 - Concrete bridges - Design and detailing rules. The calculation of load is done using computer software SCIA Engineer 10.1 and Midas Civil.

The aim of this project is to examine the welding of the upper arm of the current collector - the pantograph of the electric locomotive according the the CSN EN 15085 norm. The first part of this thesis dealt with the elaboration of all needed WPS and with the proposal of the current preparation that is going to be realized. The experimental part dealt with the practical execution of the welding as defined in the first part. The macrostructure of weldings and the process of hardening have been evaluated based on the welding samples.

Diploma thesis describes the design of a vertical heat exchanger in accordance with European standard ČSN EN 13 445-3 Unfired pressure vessels - Part 3: Design (in Czech). The first part contains the distribution of heat exchangers including an overview of the most commonly used media. The main part is aimed on the strength assessment of the heat exchanger based on the mentioned standard. The assessment equations are converted into an interactive document in Mathcad program. This allows quick evaluation of the new input parameters or easy implementation of the new parts of assessment. Checking the analytical evaluation is performed by numerical simulation in Ansys Workbench software with post-processing results according to given standard (stress categorization). The output is also the heat exchanger design documentation.

This diploma thesis is focused on determination of thermal properties of gloves by means of thermal manikin. The background research with relation to this topic together with derivation of the computational equations used for the following measurement are presented in the first part. The most significant part of this work is suggestion of procedure for measuring the heat resistance of gloves with thermal manikin based on procedure from ČSN EN 511. This methodics was verificated with 5 pairs of gloves together with analysing the uncertainties and testing the repeatability of this measurement. This work also contains the outline for all of the measured pairs with posibilities of their usage in specific situations and surrounding air temperatures. At the end of this work is mentioned brief summary of achieved results.

The thesis discusses the rural roads and their structural and technical condition. In this thesis, I focused on a specific field road near the village Tasov in the Region Vysočina. In the first part of the thesis is theoretically described retrievals distribution infrastructure and regulatory requirements for vehicles that can move on me. The second part of the thesis is focused on the design field roads that are being built in the Czech Republic. The thesis deals with concrete to field roads, which were built in the village Tasov, to which adjoins a section dealing with the difference between the then norms and standards that apply today. In another part of the thesis deals with disagreements specific field roads to the norm and the project, which was used for their preparation. In the last part of the thesis is procesed trough discussion analyzing the results that were found on rural roads in the village Tasov.

Content of this master's thesis is reconstruction of road brigre and determination of its load capacity before and after reconstruction.

Master thesis is concerned with assessing the state of information security and its use as an indicator of corporate performance in energy company. Chapter analysis of the problem and current situation presents findings on the state of information security and implementation stage of ISMS. The practical part is focused on risk analysis and assessment the maturity level of processes, which are submitted as the basis for the proposed security measures and recommendations. There are also designed metrics to measure level of information security.
