The Concept of Computer Laboratory for Non-profit Sector.
Fáborský, Jindřich ; Vinter, Miloslav (referee) ; Ondrák, Viktor (advisor)
This bachelor thesis focuses on the project of computer laboratory for the Institution of Social Care for Disabled Youth - Kociánka realized with minimum costs of production. Using the computer network with thin clients and the operating system GNU/Linux serves for minimizing the costs. The thesis includes not only explanations of principles of technology, but also an implementation procedure for this project.

Deploying thin clients and terminal servers in various environments that differ in requirements for load and performance
Králík, Martin ; Lattenberg, Ivo (referee) ; Kouřil, Jiří (advisor)
The thesis deals with possibilities of the use of terminal servers and available virtualization technologies on Microsoft, Vmware and Citrix platforms.In the first part, technical principles for virtualization are analyzed in detail and contributions to individual technologies are compared.The second part is practically aimed and deals with the suggestion of testing methodology.The testing methodology consists of identification of key factors describing user´s behaviour, which are subsequently used for selection and dimensioning of hardware architecture.The testing methodology is transformed into a scripting language and prepared for automated tests.The realized tests can be divided into groups dealing with sever load performance, monitoring data transfer, and mapping of the system time response to user´s stimulation.Thin and software clients are computed on the clients side.Performance characterizations of RDP and PcoIP protocols are monitored and compared here. On the basis of the results of performed tests two case studies for computing thin clients in the environment of The Department of Telecommunications,Brno university of Technology and in a basic school are elaborated. The first case study intended for The Department of Telecommunications is concerned with computing of VMware View technology for 150 clients. The second one supposes to compute Microsoft Remote Desktop Services in the system enviroment of a basic school for 15 clients.

Hardware realization of hospital information system
Friedl, Jan ; Roleček, Jiří (referee) ; Fedra, Petr (advisor)
The presented work concerns problems of more effective using hardware and also free software. The first part of my work presents generally free GNU/Linux distributions and this part is concentrated on two distributions. The first is Red Hat Enterprise Linux which is installed in the server of the hospital information system Clinicom. The second is live distribution Slax that is used for testing of terminal connection to the hospital information system Clinicom. The second part of my work is generally concentrated on the hospital information systems and there is presented the firm SMS solution at the end. It is the hospital information system Clinicom. The next part is generally concentrated on the workload server monitoring. It monitors both userlogins and allocated memory size. Then there are discused problems of solution of unthought-of events, for example blackout, and the one solution is described there. The last part is concentrated on implementation of the security connection to the hospital information system Clinicom and it presents live distribution Slax as distribution for thin client.

Design and development of thin client for infrastructure cloud based on Android platform
Andrle, Tomáš ; Bruckner, Tomáš (advisor) ; Žamberský, Martin (referee)
This diploma thesis deals with the issue of the development of mobile thin client application which is able to manage commercial infrastructure cloud service. The introduction section provides an overview of the necessary terminology and presents the problem domain that is a subject of this thesis. Besides the project itself, of which result is the main output of this work, is also the part dedicated to research of current theses, school information resources, guidelines, recommendations and methodologies that covers topics of design and implementation of graphical user interfaces for mobile devices, especially for those that have the Android operating system installed. Information obtained on basis of the research is after used as a default knowledge base for design and implementation of the presentation layer of the previously mentioned application. The next aim of this thesis is to make analysis of requirements for new application which is being developed. The requirements are then transformed into conceptual design, to which is bound the explanation of implementation of individual application layers. UML was mainly used for the modeling of the application parts design in environment of the Sybase PowerDesigner. The programming process was performed by usage of the development environment called Eclipse SDK. Benefit of this diploma thesis lies in the possibility of reusing its concentrated knowledge resulting from the research dealing with the problems of creating GUI for mobile devices. Programmer, who is untouched in this specialization, will be able to use this part of the thesis as a critical study material which has been verified in practice. Cloud infrastructure solution providers can find there an inspiration for their own mobile thin client application.

Linux terminal server for thin client and computing cluster
JALŮVKA, Adam
The goal of this work is to aquaint the reader with projects LTSP and openMosix. The complex sollution of the terminal server and the computing cluster with an automatic load balancing is created on the basis of these projects. This work is not only aimed at projects which are already capable to stay independently next to each other, but it is also aimed at the linkage of projects which produce benefits. The first advantage is the ability of an easy connection of new nodes to the computing cluster without the need of installation. The second advantage is that nodes can contribute with its systems resources to the terminal server and other clients.

Analysis of components for creating WUI and its application in the framework Wicket
Hybler, Michal ; Pavlíčková, Jarmila (advisor) ; Šlajchrt, Zbyněk (referee)
The aim of the theoretical part is a summary of commonly used graphics components for developing web applications in Java. In the introduction, theoretical part contains basic principles and terms related to the topic of work. Below is an overview of components, which is based mostly on documentation most widely used frameworks for building web applications. Individual components are divided into groups and there are descriptions and alternative names for each of them. Description of each component is aimed at its appearance as well as at routine use in practice. The practical part results from the list of components and categories created in the theoretical part. The first part is a description of the framework and its fundamental principles, especially creation of components. Each category and the components identified in the theoretical part are analyzed from the perspective of their applications in the Wicket framework. In the case of non-existing components in the framework are given options and mechanisms that replace the functionality of missing components.

Terminal classroom with LTSP
Pěnka, Michal ; Pavlíček, Luboš (advisor) ; Palovský, Radomír (referee)
The purpose of this work is to find out whether it is possible to implement the Linux Terminal Server Project (LTSP) on production systems such as schools, offices etc. LTSP is an open sourced system for distributing the Linux-based operating systems to limited number of thin clients using common TCP/IP networks, Small computer laboratory network, used mainly for educational purposes, is chosen for the installation, configuration and testing of the LTSP and the additional subsidiary courseware. After reading following text, reader should be informed firstly about the history, future development and use cases of the LTSP and secondly should be able to install, configure and implement similar solution in TCP/IP networks.
