Influence of magnetic field upon detection in environmental SEM
Romanovský, Vladimír ; Neděla, Vilém
The single-pole magnetic lens has been constructed and placed co-axially with the beam of primary electrons below the specimen holder. A scheme of its configuration is shown in Figure 1. The lens had to be designed with consideration to the size of space available in the specimen chamber. The situation was complicated by the necessity of placing a magnet below the specimen holder. For this reason the height of 30 mm and diameter of 55 mm of the magnetic lens were chosen. The dependency of induction B on the current I through the magnet was measured by a T-meter.

Experiment CAPEX-U: Současnost a Budoucnost
Frolov, Oleksandr ; Koláček, Karel ; Štraus, Jaroslav ; Schmidt, Jiří ; Boháček, Vladislav ; Prukner, Václav
A new pulse capillary discharge driver with a laser-triggered main spark gap has been developed. The assembled CAPEX-U device consists of a Marx generator, of a pulse forming line, a gas-filled laser-triggered spark gap and a ceramic capillary. Its design was supported by mapping of electrostatic fields in the most exposed regions and by analysis of an equivalent circuit. Operation of the laser-triggered spark gap was tested on a single-channel model. In the paper, the results of the modelling and of the first electrical tests of the whole device (capillary current and voltage at the end of pulse forming line) are presented.

The influence of implementation of DMS in a bank on its business processes
Vejmělek, Vojtěch ; Stanovská, Iva (advisor) ; Cícha, Daniel (referee)
The topic of this thesis is an analysis of the influence of implementation of Document management system (DMS) on a selected process of a specific retail bank. The paper moves from a detailed characteristic of key terms, apart from technological aspects deals with the current legislature, continues on to the current state of the selected process and ends with a proposal of a new process. The thesis is meant for those who are interested in the field of enterprise content management, additionally it can offer motives for thoughts about electronization of documents and how it can be used to better the organization's services.

Physical Load Analysis In Woman's Beach Volleyball
Maciolková, Hana ; Vorálek, Rostislav (advisor) ; Buchtel, Jaroslav (referee)
Title: Physical Load Analysis In Woman's Beach Volleyball Objectives: The objective is to examine time characteristics, cardiac strain, movement pattern and the individua! volleyball skills in woman playing beach volleyball. The results will help aid athletes and coaches to improve individua} and team performance in the sport. Methods: Analyses of the thirteen game records were used to compile data for statistical time measurements, movement pattems and individua! volleyball skill. Through the use of sport testers, four individua} athletes in four separate toumaments had their heart rates recorded. These heart rates were further analyzed to collect the appropriate data for cardiac strain characteristics. Results: The average game time was 37 minutes with 5 - 9 seconds exercise loads and 15 seconds recovery time. Beach volleyball is high to middle level intensity game with mixed aerobic- anaerobic energy supply system in use. The average heart rate falls in the interval of 150 and 180. The jumping load is about 41 and more jumps counting serve jump, block and spike. The prevalent movement distance is within 4 meter range. The results also shows that the blocking player is under large physical stress while changing repeteadly position between defence on the net and in the field. Keywords: Beach...

Computational analysis of the dynamic behavior of the thrust bearings
Žatko, Miroslav ; Kos, Pavel (referee) ; Malenovský, Eduard (advisor)
This master´s thesis solves the problem of stationary viscous flow of incompressible fluids in thin layers of fluid film lubrication in fixed pad thrust bearings. The parametric computational model of oil domain was created for investigation the distribution of pressure, velocity and thermal fields together with the determination of the basic parameters as axial force, heating up and friction loss. Subsequently this model was applied for investigation influence of uneven bearing clearance. The problem task was solved by final volume method in Ansys CFX 12.0 software.

Fast Food Restaurant Business Plan
Hýbl, Jan ; Hartman, Ladislav (advisor) ; Habrmanová, Blanka (referee)
The aim of this diploma thesis is to execute a business plan for a business in the field of fast foods. The main goal of the business plan is to evaluate feasibility and practicability of this project. The master thesis is divided into two main sections: a theoretical and practical one. The first part describes the entrepreneurship, small & medium enterprises in Czech Republic and a business plan. Moreover, it focuses on theoretical background that consists of principles, methods and approaches that should be respected when writing a business plan. In addition, it describes parts of a business plan. The second part deals with the business plan for the project itself that is based on the theoretical background. The evaluation of this business idea in terms of its aspects is then provided.

Rozvoj a aplikace digitální obrazové korelace
Jandejsek, Ivan
The presented work devotes to the methodology and related software development for Digital Image Correlation (DIC). DIC is used for experimental mechanics studies. It is the non-contact technique (Optical or X-Ray) that provides full-field and high resolution measurement of displacements and strains within an object subjected to loading.

Design in Tourism
Korcová, Natálie ; Jarolímková, Liběna (advisor) ; Bakos, Tomáš (referee)
The thesis deals with the position of design in tourism and is focused on the Czech Republic, mainly Prague. The thesis includes in consolidated form all the available information concerning design in tourism and can easily serve as an overview on the topic. Additionally in the final part it shows the ways how the design could be worked with in tourism and how it can be developed. There are discused two points of view -- the point of view of the service providers and the point of view of the institutions. The theoretical part deals firtsly with the connection between design and tourism, then with the importance of design attractivities in tourism and subsequently those are catagorized. The contribution of the theoretical part lays in setting design into wider context and defining its role in tourism. Besides that it also justifies the role of design from many points of view -- economic, psychological and environmental. The practical part deals with forms of intermediation of design in tourism and with activities of institutions in this field. The contribution of this part is defining the design-aware trends in activities of those institutions.

Numeric simulation welding of the turbine vane and rotor
Dohnal, Ivo ; Slováček, Marek (referee) ; Daněk, Ladislav (advisor)
Numeric simulation welding of the turbine vane and rotor - master’s thesis is ordered by the Siemens Industrial Turbomachinery ltd. company. Simulation welding is done in program SYSWELD. Used welding materials are X22CrMoV12-1 (turbine vane), 30CrMoNiV5-11 (rotor), TOPCORE 838 B (additional material). These are temperature-resistant and fire-resistant welding materials. The SYSWELD program works on the principle of finite elements method. By SYSWELD is done the evaluation of temperature and stress fields and material structure after welding. Here is a part , which deals with computations of welding crevices.
