(English) The thesis examines the influence of information and communication technologies on the automation of library management processes and services as well as their applications, with a key consideration of the environment of the District Scientific Library of the city of Liberec. The introductory chapters briefly describe the development of basic international standards for data processing and communication networks in the world. The following chapters deal with the implementation of automated library management systems and networks in the Czech Republic in the early '90s, including accompanying projects that formed an inseparable part of the development. The development of automated library management processes and services in the District Research Library of the city of Liberec from the 90s till the end of 2010 becomes the core subject hereby examined. This is closely related to the parameters of the selection and application of the library management system, including the specific features thereof, as well as its internal utilization by librarians and its utilization by external users. The external use of the library management system has been evaluated through a survey of the use of online information sources and services sought by and provided to registered users. Taking into account the...

Efficient shortest path search in the public transportation networks
Martínek, Vladislav ; Kopecký, Michal (referee) ; Žemlička, Michal (advisor)
The search for the shortest path is one of the most studied graph problems with interesting applications in various elds. One such eld is human mass transportation, where the path length depends on the time tables of the tra c relations, which implements the path. Goal of this study is to nd efficient algorithm for the shortest path search in human mass transportation network and implement it in the library, which will be also useable on portable devices. The possibilities of time tables preprocessing and use of heuristics on search acceleration will be explored during implementation.

Face Recognition in Social Networks
Mach, Pavel ; Skopal, Tomáš (advisor) ; Kolomazník, Jan (referee)
Popularity of face recognition in image galleries and social networks is growing. But none of these real world applications let the user adjust parameters. The goal of this thesis is to develop a library for face detection and recognition which can be easily used in some other program and also a web application recognizing faces, with environment similar to the one of social networks, which uses the library. Of course we do not try to compete with big social networks in the field of face recognition, because it will be almost impossible due to their enormous databases. In the experimental part of the work we try to find most suitable parameters such that face detection and face recognition would be as accurate as possible.

Functional reactive programming for web applications
Smrž, Roman ; Pudlák, Petr (advisor) ; Hric, Jan (referee)
Functional reactive programming provides mechanisms of describing dynamic systems in a declarative and type-safe manner, which is traditional domain of functional languages in general and Haskell, which we use here, in particular. We explore ways, in which it may be applied to programming web applications, specifically, we design a domain specific language intended for writing web pages as a part of a Haskell program, which would generate the actual code served to the client, and enriching them with dynamic content; and also find out to what extent we may broaden the expressive power of such library given certain inherent constraints of the chosen method. In doing so, we utilize the tree-like structure of the HTML page, which is quite suitable to be written as a source code in a programming language and to which we embed additional entities providing the dynamics and interactivity.

Educational Game of Motivation on the Android Platform
Kučera, Martin ; Očenášek, Pavel (referee) ; Kreslíková, Jitka (advisor)
The aim of the dissertation is to create a prototype of an educational game which should help students with the choice of future their studies. To this end, the game introduces the topic of logic systems in a non-threating interactive way with clear illustrative examples. The theoretical part of the work deals with the background knowledge necessary in order to design the game. It explains logic systems, gates, flip-flop circuits, and explores various aspects of game genres with primary focus on puzzle games and their history. In addition, the dissertation presents some of the issues related to cross-platform development of games for both mobile and computer platforms, and provides brief descriptions of several popular cross-platform libraries. Lastly, the work introduces and compares several chosen applications created as a supplementary material for teaching logic system.

L-systems online
Fišer, Marek ; Pelikán, Josef (advisor) ; Mráz, František (referee)
An L-system in its simplest form is a variant of a context-free grammar. Originally, L-systems were developed and are still mainly used for modeling plant growth, though with L-systems it is possible to create general fractals, models of towns or even music. However, anyone interested in L-systems and wanting to experiment with them may have difficulty finding an appropriate application. The goal of this work was to create an online system, suitable for a wide range of users, for working and experimenting with L-systems. The resulting solution consists of two parts. The first part is a universal, easily-expandable library for processing L-sys- tems. Expandability is achieved thanks to its modularity. All input is processed through interconnected components that are specialized in particular activities. The specialization of the components also contributes to the clarity and reliability of the whole processing system. The library is independent and multiplatform and can thus be readily used in other applications. The second part consists of a modern web interface designed to be under- standable for beginners and yet also capable of providing advanced features for more advanced users. Part of the site is a gallery of L-systems to which each user can contribute and which thus helps to create a user-community. The...

The Diploma Thesis is dealing with questions of investment decision-making in the area of IT and can be a complete guidance on the basic concepts of decision-making on the investment projects, methods of financial evaluation of such projects and the ways of its application in the sphere of IT. It is mainly aimed on the projects dealing with internal processes in IT organizations and optimalization of its management ? IT Service Management (ITSM). The paper deals with existing methodologies and standards applicable to IT Service Management and closely works with the latest library of best practices ITIL V3. The introduction gets the reader into the basics of the IT management, introduces the existent market standards and creates a liaison between the IT and business in questions of investments. The second part pays attention to the principles of ITSM and describes the benefits that can process optimalization bring to the company. The third chapter opens up the IT investment topic and introduces various methodological concepts and models used not only in the classical financial theory, but in the modern management practice as well. It offers a basic overview on the methods of investment project evaluation, e.g. Net Present Value (NPV), The Payback Period Method, The Internal Rate of Return (IRR), The Profitability Index, and the most popular one ? Return on Investment (ROI). The following chapter applies the measure of Return on Investment (ROI) to the projects of ITSM implementation according to ITIL. It shows the basic principles of the method usage, describes its main components and introduces the way of identification and evaluation of the benefits, which those projects bring to the business. Gained knowledge is based on the real practical examples ? several worked-out business cases created for the customers of the Hewlett-Packard Company. The last part of this chapter shortly describes several software tools for building the similar business cases and their own methodology. The last chapter in devoted to the situation on the local and world market and addresses the practical application of the methods of IT projects evaluation in the companies. The conclusion then summarizes important parts and key elements of the paper.
