For the grid to be stable, the supply of power must equal the demands of the consumer at every moment during the day. The unpredictable intermittent nature of wind results in inconsistent power generation. Energy storage technologies coupled with a wind farm can not only provide power during fluctuations but also maintain a stable and reliable grid. The objective of the thesis is to perform a comprehensive analysis of different types of energy storage technologies that can be coupled with a wind farm. The analysis is performed on the basis of multiple characteristics which affect their viability. We identified key characteristics for a range of storage technologies, including lead-acid, sodium-sulphur, nickel cadmium, lithium-ion, superconducting magnetic energy storage, electrochemical capacitors, flywheels, flow batteries, pumped hydro and compressed air energy storage systems. We performed a comparison study to analyze trade-offs and assessed potential improvement areas that will make them more competitive in the electric power industry. We suggested viable energy storage systems that could be better and suitable for different applications for an electric grid integrated with a wind farm.

As satellites become smaller, cheaper, and quicker to manufacture, constellation systems will be an increasingly attractive means of meeting mission objectives. Optimizing satellite constellation geometries is therefore a topic of considerable interest. As constellation systems become more achievable, providing coverage to specific regions of the Earth will become more common place. Small countries or companies that are currently unable to afford large and expensive constellation systems will now, or in the near future, be able to afford their own constellation systems to meet their individual requirements for small coverage regions. The focus of this thesis was to optimize constellation geometries for small coverage regions with the constellation design limited between 1-6 satellites in a Walker-delta configuration, at an altitude of 200-1500km, and to provide remote sensing coverage with a minimum ground elevation angle of 60 degrees. Few Pareto-frontiers have been developed and analyzed to show the tradeoffs among various performance metrics, especially for this type of constellation system. The performance metrics focus on geometric coverage and include revisit time, daily visibility time, constellation altitude, ground elevation angle, and the number of satellites. The objective space containing these performance metrics were characterized for 5 different regions at latitudes of 0, 22.5, 45, 67.5, and 90 degrees. In addition, the effect of minimum ground elevation angle was studied on the achievable performance of this type of constellation system. Finally, the traditional Walker-delta pattern constraint was relaxed to allow for asymmetrical designs. These designs were compared to see how the Walker-delta pattern performs compared to a more relaxed design space. The goal of this thesis was to provide both a framework as well as obtain and analyze Pareto-frontiers for constellation performance relating to small regional coverage LEO constellation systems. This work provided an in-depth analysis of the trends in both the design and objective space of the obtained Pareto-frontiers. A variation on the εNSGA-II algorithm was utilized along with a MATLAB/STK interface to produce these Pareto-frontiers. The εNSGA-II algorithm is an evolutionary algorithm that was developed by Kalyanmoy Deb to solve complex multi-objective optimization problems. The algorithm used in this study proved to be very efficient at obtaining various Pareto-frontiers. This study was also successful in characterizing the design and solution space surrounding small LEO remote sensing constellation systems providing small regional coverage.

The aim of the "Quality management system in the selected company" dissertation work is an analysis of the current situation of the quality management system in a company and make suggestions to improve the current system. For my dissertation work I have chosen engineering company Motorpal, a. s., which is the engineering company and the one of the leading producers of devices for diesel engines to tractors, ships and construction machine.The work consists of two parts, theoretical and practical. The first part describes terms like quality, importance of quality, factors that affect quality, management principles of quality, economy of quality, quality in pre-production stages, quality planning and quality control tools. The second part is primarily focused on the quality costs, which is the most problematic part of the quality management in the company. In this part of the dissertation work is also briefly described the company and its history, company's production program and customers and company's financial situation, processes and quality management system.

The thesis is focused on the production management company XY. In the first part, there is the theoretical knowledge required for the understanding of this problem and diploma thesis. In the second part there is the analysis of company processes. Based on the identified problems the methodology of improvement is designed in this section.

The aim of this diploma thesis is to create and apply a methodology to improve the manufacturing process. Processes for the passage of a contract through the company and activities of the foreman were analyzed. According to this analysis, a methodology was created for continuous improvement of the manufacturing process. This methodology was applied to the data obtained in the analysis. Based on the application of the methodology, actions have been proposed to improve the production process.

The thesis is focused on reducing number of nonconformities using quality tools in the company engaged in dyeing and finishing of textile materials. The aim is a proposal of nonconformities management system. Based on analysis of the current method solving nonconformities are designed registration processes of internal nonconformities and complaints, which are followed by evaluation of nonconformities. The proposal will result in a systematic approach in solving of nonconformities.

This diploma thesis deals with a Six Sigma method, about especially analysis defects of forms for tire production company Barum Continental. In the first, theoretic part, there is the Six Sigma method, improvement method and implementation into practice defined, and at last I attended to the tools of Six Sigma method, e. g. Control Charts, Regression analysis, Pareto analysis. In the second, practical part, there is the industrial process analyzed. Then I was introduced Barum Continental spol. s.r.o. concern, which data extended. Up to data processing I was used tools of Six Sigma method and also histogram.

Theme of the Master’s thesis is analysis of process for production of small plates. Main parts of the thesis are analysis of the production process, process mapping, data capture, analysis of the data by Pareto analysis and find causes of nonconformities. Causes analysis is based on data analysis and process observation. It is divided to chapters by factors which are influencing the process. Optimization measures are designed with regard to their simplicity of realization and system in organization.

This thesis is about the monitoring of testing station downtimes at the DS/ETC (Diesel Systems / Engineering Testing Center) Bosh Diesel s.r.o. department in Jihlava. The goal of the monitoring is to get a record and an immediate warning for each machine downtime. The testing engineers are able to edit downtime reports and to create statistics and the Pareto analysis based on the reports. In the beginning of the thesis there are generally described the ETC department and the SCADA system. The monitoring system is designed and implemented based on the requirements of the ETC department. SMS messages sent via a GSM module what is connected directly to the server are used for immediate downtime warning. The test engineers have the graphic user interface what they can use to edit downtime reports. Statistics are generated individually based on the adjustable data filter. The department can focus primary on the finding out the reasons of the downtimes what leads to the biggest reduction of the test machine downtimes.
