Wireless 802.11 IP Networks and their models in the OMNeT++ simulation tool
Jakúbek, Peter ; Burda, Karel (referee) ; Růčka, Lukáš (advisor)
The bachelor work concentrates on familiarization with the standard IEEE 802.11. The work summarises the advantages, disadvantages, history and grouping of this standard according to norms. The great attention is paid to a user’s familiarization with the stimulating tool OMNeT++ and its extension Inet Framework. This extension helps to amplify the simulator for a supporting modelling of wireless nets. It supports models of a few protocols such as IP, UDP/TCP, Ethernet, PPP, IPV6, OSPF, RIP, and MPLS. It includes already programmed API modules from which is possible to create easily a wireless IP net.Programmes needed for a proper functioning of the OMNeT++ are described in corresponding paragraphs. A part of work deals with an installation and setting of programmes for accurate functioning of a compiler surrounding. Our work analyzes possibilities and manners of simulation of wireless IP nets which helps to create basic simulation model represented by standard 802.11. There are also included laboratory works in our bachelor work, which includes theoretical introduction to studied issues. Tasks are concentrated on ad-hoc and infrastructure mode. These tasks comprise of theory of problematic, detailed instructions for creating together with explanations, processed results and output of simulation

Wireless model 802.11 in NS2
Botta, Miroslav ; Kubánková, Anna (referee) ; Šimek, Milan (advisor)
Theme of this work is simple wireless simulation Network Simulation 2 tool. The work consists of more parts. In the first section is basic theory about Wi-Fi networks, they types and standards and describes how useful can it be in practical life. In the second section there is a short annotation for programming in TCL language and possibilities of NS2 for simulating wireless networks. In the end there is a complex simulation of this network. In the third part there are two complex tasks where the information’s are drawn from the previous two parts.

State of photovoltaic in the Czech Republic
Lukášek, Kamil ; Bača, Petr (referee) ; Vaněk, Jiří (advisor)
Photovoltaic in the Czech Republic has gone through significant development during last few years. The thesis describes physical principle of converting solar energy into electrical energy using photovoltaic cells. Photovoltaic power plant is a set of technologic components connected together to utilize solar energy and convert it into electric energy that could be distributed to electric power network. Review of the photovoltaic development in the Czech Republic and the list of the biggest operational photovoltaic power plants present important data for assessment of the current status of photovoltaic technology in the Czech Republic. Chapter operations and maintenance of photovoltaic power plants summarizes the most common causes of failures and presents diagnostic tools for service requests. Due to legislative changes, hybrid photovoltaic power plants construction has been prioritized as it is economically more efficient now. Construction of new hybrid photovoltaic power plant was assessed analytically using SWOT analysis that evaluates strong and weak sides of the projects in comparison with opportunities and threats of construction. After evaluation of obtained data the next steps of the hybrid photovoltaic power plant’s construction plan are proposed. The first part of hybrid photovoltaic power plant design contains PVGIS program's data evaluation, which provides sunlight intensity information for specified area. Obtained data were used in the second part of the design to determine proper components selection for family house hybrid photovoltaic power plant. Finally the economic view of the design and return of investments were assessed.

Improving of reliability for NPP
Dubovský, Dávid ; Šen, Hugo (referee) ; Nerud, Pavel (advisor)
The aim of this paper is to describe and evaluate the reliability of nuclear plants at Bohunice (EBO). Then illuminate the methods for increasing the reliability and specify one of them (INPO AP 913). After describing the methods, summarize the work results of this method and proposes the way of application.

Application of an Integrated Model of Management and Design of Balanced Scorecard in the Organization
Matulková, Lenka ; Lešetický, Ondřej (advisor) ; Pirožek, Petr (referee)
The thesis is focused on management analysis of the selected organization in terms of components and factors that are then used to design of the system of strategic management Balanced Scorecard. The first part is focused on describing the theoretical background concerning the issue of the effect of the organizations administration and management. Comprehensive evaluation of the level of management is performed in the second part. Organizational performance is assessed using the Balanced Scorecard method. Particular perspectives, strategy, targets and their measurements are determined for organization. The interdependence of the targets is presented in the Strategic Map. The conclusion is made by evaluating the achieved findings and formulating specific recommendations for the selected organization.

N + N compounds and their typology
BIEBLOVÁ, Marta
Subject of the Bachelor work is a research of compounds (compound words) in the Italian language from 1950 to 1960. The work is divided into two parts. The particular chapters of the theoretical part are being dedicated to the formation, characteristics and division of these compounds according to the characteristics and the relations among the singular components. The selected compounds of the type N + N which were originated in the above mentioned years are being analysed in the analytical part. With the composition of ?the selected compounds? we keep in mind that it does not deal with neo-classic compounds, loan-words from foreign languages or compounds of different type than is the type of N + N, but it is related to only Italian compounds which are always composed of two nouns. The aim of the work at these excerped compound words is the determination of all characteristics which we considerated in the theoretical part and we are trying to find out in what branches these compounds are asserted the most. Next challenge of the work is to find if these compound words are used in current Italian.

Business Intranet of Ferona
Kos, Jiří ; Voříšek, Jiří (advisor) ; Pecha, Tomáš (referee)
Information management has begun to gain importance very fast during the time of internet business, auctions, stock exchanges, in the time of increasing number of international companies. Nowadays very often mentioned topics are how to obtain and deliver right information at the right place in the right moment, how to communicate with business partners, collaborators, superiors. Intranet belongs among devices for information management and I deal with just this theme in my diploma work. The defining of Intranet belongs to main aims of this text i.e. terminology, elements, principals of function, current trends and also giving instructions for building or reconstruction of company intranet. The detailed study of current trends during building company information system, case studies and instructions according to "Best practices" was the way how to achieve defined goals. I gathered information mainly from internet information sources which deal with this topic, mainly from foreign servers. I can see the contribution of my diploma work that it tries to give instructions for managing the project building company intranet, its timing and it draws attention to critical factors of success. The suggestion of new appearance of company intranet is the culmination of my diploma work. The work is clearly structural -- I present the explanation about problems of company information system in the theoretical part, in the practical part I deal with finding out of main lacks and formulation demands of new appearance of company intranet and at the same time I suggest possible new appearance. I evaluate achieving defined objectives and sum up main ideas in the conclusion.
