Study of implementation of SPC statistical method for control of technological operations
Ondruška, Jan ; Zeman, Karel (referee) ; Jurová, Marie (advisor)
The master’s thesis contains a procedure of implementation of statistical process control for a machining process in a chosen company. The method is based upon knowledge of this topic which are mentioned in the first part of the thesis. The output is a comparison of general process performance before and after implementation of the above-mentioned statistical method and evaluation of the influence of this new method at the process. The comparison is done using hypothesis testing of specific statistical variables and analysis of process performance and capability of both data sets. The acquired knowledge and experience will be used for implementation of statistical process control for other processes in the company’s production portfolio.

Methods of measuring bit rates
Franc, Jan ; Mišurec, Jiří (referee) ; Zeman, Václav (advisor)
Study and basic benchmarking methodology description of network connections based on the IP was the objective of bachelor work. I resulted above all from RFC standards, by which are directed most of Internet protocols. Particular procedures for testing are explained in RFC 2544. On the basis of parameters analysis, I suggested conception and gave shape to web application which allows identify referenced basic transfer parameters of Internet connection (downstream, upstream, latency, scattering of connection speed). Application doesn’t require no add-ons and modules on user side. It is built on server programming language PHP with usage of relational MySQL database, in which are stored data. Client scripting language JavaScript is also used. Application offers measuring of mentioned parameters both to visitors and to registered users. Matter of course is user registration; work with history of carried out measuring, sending private messages between registered users. Above whole application exists administrator account.

Methods for the measurement of bit rates in data networks
Franc, Jan ; Martinásek, Zdeněk (referee) ; Zeman, Václav (advisor)
The target of this master's thesis were the known methods for testing the quality of transfer parameters of data networks. I have studied the RFC 2544 document to analyze these tests. From that information and by studying other existing web-based applications I was able to design a concept of my own application that will allow to measure basic quality parameters of transfers made through the Internet (the parameters: downstream, upstream, latency, variance of these and a traced route). My application doesn't require any modifications on the user's system. It's built on the server-based programming language PHP and uses the relational database engine MySQL to store measurement and user data. On the client side, it's assisted by the JavaScript scripting language. Both registered users and visitors are allowed to perform the listed measurements. Registered users are able to browse the history of their own benchmark results and also to send messages to others. There is an administrative account to oversee the operations. Another part of my thesis work is an application for Windows that performs the same measurements but does not use JavaScript.

Project of PV System for a Commercial Building
Zeman, Daniel ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
The main purpose of this work is to describe the basic principles of PV modules and to define the conditions for the construction of PV systems. Define the differences between the various types of PV systems and for the selected object handle system design in accordance with applicable legal conditions. For the proposed technical solution to handle complex energy-economic analysis conducted by the proposal. The work also ncludes procedures for calculating the various parameters that have been known for the correct design of the entire system in a given location during temperature changes and changes in solar irradiance.

Suggestion of Financing of a Housing by Estate Agency´s Clients
Máčková, Zuzana ; Grmela, Jan (referee) ; Zeman, Václav (advisor)
The thesis mainly deals with the most important financial products at real estate market. The first part deals with certain types of mortgage loan, its collateral, process for execution and fees for processing, maturity and possibility of maturity the mortgage loan. It also includes the issue of building savings, its functions, purpose, minimal time of savings, interest rates and eventually also loan from building savings. The second part focuses on the offer of mortgage loans, building savings and subsequent comparison of these products on model example.

Integration of microstructure informed enrichment base functions
Ladecký, Martin ; Zeman,, Jan (referee) ; Eliáš, Jan (advisor)
This thesis deals with problems related to the numerical integration of rapidly oscillatory functions. Analyze classical methods of numerical integration and compare them with method published by David Levin\cite{levin82}. Levin's method is applied in solving Laplace differential equation that describes deflection of membrane. To solve potential problem is used hybrid finite element method with Trefftz bases functions.

Tax Heavens from Czech Republic Perspective
Zeman, David ; Hodinková, Monika (referee) ; Kopřiva, Jan (advisor)
In the theoretical part this work deals with the concept of tax havens, their distribution, use and selection. The second part compares three companies in the Czech Republic with a turnover of hundreds of thousands to several millions, and it demonstrates which for them would be advantageous or disadvantageous - to operate in the tax haven compared to staying in the Czech Republic.

Server application to process data from a MySQL database and their interpretation
Gardian, Ján ; Zeman, Kryštof (referee) ; Červenák, Rastislav (advisor)
Diploma thesis is about creating server application that process and interprets data from the database. Main aim of such application is able to process a large number of database requests in real-time environment. Provided database contains records of measuring download speed and quality of mobile connection via different radio technology from various providers. Those measured data are sent from users all around the world and amount of data collected is still growing. Therefore created server application can adapt to increasing size of database thanks to aggregation. This method of aggregation and use of index in database tables are further discussed in the theoretical part. Mainly putting indexes in tables produce significant acceleration of processing database requests. Final product of this thesis is an application that consist of three components: a server application running aggregation, website that interprets measured data and back-end interface providing measured data as well. Data at the website are presented in form of graphs for different countries and used radio technologies. Web address and user manual for finished applications are provided in the fourth chapter of diploma thesis. In the last part of thesis are performed various speed tests of programmed application that confirm the effectiveness of selected and described methods to accelerate work with the database.
