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.

Building and use of smaller computer networks
Kyzivát, Marek ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
The thesis describes the initial state of the computer network Basic Schools and Kindergartens Ohradní (ZŠMŠ Ohradní) in Prague 4 and then its reconstruction, which I largely contributed. ZŠMŠ Ohradní consists of four pavilions and from one building on the other side of the street. The aim of this study is to assess the initial state of the network and point out the shortcomings that we discovered. We found deficiencies in the operation stress tests, measurements and data cabling overall analysis. Original networks connectivity was 100Mb/s. Together with a colleague, we are network administrators. Furthermore, I am going to introduce a new form of network, which has identified deficiencies improved, by using on newer technologies. I will describe its structure, address allocation, active and passive components, and operated services. New network is capable of 1Gb/s, and its spine is going to be 10Gb/s soon. Benefits of this reconstruction is faster, more stable and more modern network that will facilitate the work of employees of ZŠMŠ Ohradní. To these improvements, I have mainly contributed by measurements. I participated in the design and implementation of new form of data network. I collaborated with fellow Poc to the configuration of active elements and network services in reconstructed network.

Design of processes of business department in IT company and measuring their performance
Schütz, Martin ; Oškrdal, Václav (advisor) ; Bruckner, Tomáš (referee)
The thesis deals with design of new processes of business department in IT company which provides server hosting, web hosting and domain registration services. These processes come from identification and analysis of current processes and the theory of business department management. Key Performance Indicators (KPIs) were set for selected processes which can be used for managing the company as a whole. Models of processes were created due to EPC notation. New processes were designed to continuously create data in CRM information system providing evidential and information support necessary for business department management, including the possibility of measuring its performance. Processes also automatize often repetitive activities and provide relevant information to other affected business units within the company. Contribution of the thesis lies in results of analysis of current identified processes containing solution proposals of discovered problems and newly created process models. Both can be used as a pattern for optimization of current processes in already existing organization or for designing new process models in new organization in the same or similar field of business.

Comparison of Business Intelligence implementation using open source solutions for middle size companies
Schmidt, Róbert ; Maryška, Miloš (advisor) ; Sládek, Pavel (referee)
The main goal of master thesis is to analyze and propose possible low cost Business Intelligence solution with open source technologies and comparison of available tools for implementation in middle size company. We compare Pentaho and Jaspersoft tools implemented on local hardware and cloud environment with Microsoft Azure services. The theoretical part focuses mainly on understanding the business intelligence and its architecture, because architecture is an important part of the work. Actual tools are designed as stand alone modules for specific activities in the business intelligence lifecycle. Low cost tools are often connected with open source technologies and cloud computing. This part of the work contains explanation of these terms and their advantages and disadvantages for our chosen target group of companies. The analytical part includes defined parameters by which it is conducted analysis of tools and their comparison. Business Intelligence solutions are divided according to arcitectural layers. The evaluation criteria are divided into financial, technical and user category. In conclusion, chosen tools are compared and evaluated. The main contribution of this thesis is comparison of open source business intelligence tools for implementation in middle size company. According to the EU directive, middle size company does not exceed 250 employees or profit is less than 50 million euros. The reader can compare the different solutions and their pitfalls or shortcomings that could be critical for the implementation.

Permeation of VOC vapours through carbon nanotube network membranes controlled electrically
Slobodian, P. ; Říha, Pavel ; Olejník, R.
In this letter, we report the increase of permeation rates of some typical volatile organic compounds through entangled carbon nanotube networks by an electric current. The change in the permeation rate is reversible when the\ncurrent is turned off. The permeation rise is partly probably due to Joule effect and thus increased membrane temperature and vapor pressure in the vicinity of the inlet side of membrane. However, the effects of vapor polarity and electrostatic interaction of vapors and charged nanotubes seem to be also involved and contribute to the differentiation between alcohol and carbohydrate vapors permeation.

The tax system reduces motivation to return to work among mothers with young children: recommendations and evaluation
Šatava, Jiří
In the Czech Republic, the overall taxation of work, i.e individuals' income tax together with social security and health insurance contributions, places a heavy burden even on the relatively low earnings of so-called second earners in households, i.e. partners with lower earnings. These peoples' work activity is, however, generally very sensitive to the level of taxation. A large group of these earners is made up of mothers with young children. Mothers who are the second earner in their household are subject to a participation tax rate (PTR) up to 30 % higher than their partners, and yet a higher PTR results in lower motivation to work. Women with children and low earning potential are subjected to the highest PTRs in comparison with their partners.
