Project metods utilization /disposal waste from selected machine works
Šíma, Kamil ; Nekvasil, Richard (referee) ; Novotný, Pavel (advisor)
The topic of my master’s thesis is waste management issue in selected engineering company with focus on industrial wastes. With use of information gained from selected engineering operation there is mentioned its brief characteristics, details about individual operations and products, impact of company activities on environment, facts about quantity of produced wastes and summary of current ways of waste management. On the basis of review of gained information there are suggested measures in the master’s thesis which realization would mean not only increase of material and energy utilization of produced waste, increase of degree fulfilment of waste economy and decrease of quantity of wastes placed in dump, but, in the long term, betterment of economical situation of company and its image.

Transfer of production to China
Janek, Michal ; Halík, Jaroslav (advisor) ; Jezný, Tomáš (referee)
The thesis is focused on transfer of production to China. The aim of the thesis is to evaluate the potential of China from the perspective of companies and investors, and on the example of the international company to highlight not only the traditional ways of entering the Chinese market, but also the specific method that considers the needs of manufacturing companies. Thesis also contains the assessment of competitiveness of the Chinese economy, cultural differences and comparison of the various forms of entering the Chinese market. The practical part is focused on the analysis of enterprise from the polygraphic industry which has transferred part of its assembly processes to China. Conclusion contains recommendations for further development of the company on the Chinese market.

Propagation of inclined cracks to the interface of ceramic laminates
Novotná, Lenka ; Trunec, Martin (referee) ; Chlup, Zdeněk (advisor)
Composite materials with laminated structure provide advantages which are utilised during component design. Low density, temperature and chemical stability are the profitable properties predetermining application of ceramic laminates. The main obstacle for wide spread of ceramic materials is their inherent brittleness. Therefore, in this thesis, the crack propagation in ceramics laminates has been extensively studied. Laminated structures with various volume fractions of components (alumina and zirconia) were prepared by electrophoretic deposition. Evaluation of crack propagation through the interface and determination of basic mechanical properties was conducted on the basis of extensive literature search. Crack deflection originated in both presence of internal stresses and differences in elastic modulus during the crack interface passing was monitored. A special type of specimen geometry was employed with the aim to set arbitrary angle between crack and interface. It was experimentally found that the degree of crack deflection is dependent on entering angle and volume fraction of components. Higher crack deflection was already found in the bulk of the test piece comparing to the test piece surface. The 3D fracture surface reconstruction generated using laser confocal microscopy was used in this detailed crack propagation study. Further basic elastic and strength characteristics of laminates were determined and compared to those obtained from monolithic materials. The validity of the mix rule for elastic characteristics was confirmed by comparing of elastics modulus. The most reliable method for elastic modulus determination was marked the dynamic resonance method due to low scatter and consistency in measurement. The flexural strength of all laminates tends to be close to the flexural strength of the weakest component. Therefore the mix rule is not applicable for flexural strength estimation on the contrary of elastic characteristics. The change of component volume fraction leads only to change of flexural strength scatter. Thanks to gained knowledge about crack propagation and basic characteristic determination will be possible to design ceramic laminates more efficiently for given needs of application.

Sustainable tourism development of Vysocina Region
Veselá, Markéta ; Macháček, Jaroslav (advisor) ; Vondráková, Zuzana (referee)
The diploma thesis deals with the topic of sustainable tourism development at the regional level. This phenomenon is elaborated on the example of Vysocina Region. To evaluate sustainability of its development, the potential of this touristic destination is researched regarding various areas, including key products. These are subjected to comparisons with recommendations of significant tourism organization for the purpose of assessing the sustainability of tourism. The diploma thesis also includes a comparison with other Czech regions experience as a touristic destination. Vysocina Region has favourable initial conditions for its sustainable development, especially regarding supply of key products, which include both environmentally friendly goods and cultural attractiveness contributing to the personal development of individuals and promoting intercultural tolerance. The main issue appears to be the spatial imbalance of its development in the region, caused mainly by the concentration of tourist activities to certain areas and low local initiative in the less attractive areas. The diploma thesis proposes a number of solutions, such as utilization of geocaching and products of gastroturism, supporting the foundation of local destination management organisations, promoting cycling tourism and the foundation of highly visited tourist destinations.

Influence of rotating wheels on vehicle aerodynamic characteristics
Oslizlo, Aleš ; Svída, David (referee) ; Vančura, Jan (advisor)
The diploma thesis is focused on computational examination of influence of boundary condition settings in CFD software on the final aerodynamic characteristics of a vehicle. The flow analysis is carried out around a vehicle with and without the rotation of the wheels and along with the stationary and moving road. Furthermore, there is demonstrated the method of the CFD model composition and there is described the influence of rotating wheels on vehicle aerodynamic characteristics.

Design of a methodology for BI solutions in QlikView environment
Judová, Eva ; Pour, Jan (advisor) ; Kunst, Jan (referee)
This master thesis is devoted to a design for methodology of BI projects in QlikView. The main aim is to propose a recommended procedure solutions reflecting the strengths and weaknesses in the development of QlikView applications. Accompanying chapter to the discussed issue is a chapter Business Intelligence which explains the principles, characteristics and reasons for implementation in companies. Part of defining the differences between traditional and self-service solutions serves as a theoretical basis for understanding the increasing attractiveness of self-service solutions and environment of the proposed methodology. The next chapter presents the company Qlik as a market leader in BI and the owner of QlikView. The reasons for its establishment, subsequent development and actual vision are listed to create a comprehensive view of the environment where the described product was created. Along with the chapter focusing on characteristics and main advantages of QlikView a knowledge base is established for the implementation of proposed methodology. Crucial chapter of this thesis is based on the author's experience gained while implementing QlikView projects. The proposed methodology is based on the description of each phase, its activities, inputs and outputs and its concrete application in a demo environment for the area of receivables in manufacturing company. The key contribution of the author is pointing out potential problems during development or warning about critical parts or providing appropriate recommendations and benefits of the proposed procedures. The designed methodology can serve as a useful guide for self-service projects implemented the QlikView environment.
