Interactive Multi-user Virtual Environment
Okon, Hynek ; Máša, Michal (referee) ; Žára, Jiří (advisor)
The thesis proposes an extensive new system for virtual world hosting and management. The system is designed to o er real-time 3D graphical representation of the virtual world, to communicate and exchange data over a public network, to allow for automatic distribution of major changes in the virtual world to client installations, to allow clients to fully de ne the contents of the world and also to create new worlds directly via the client software interface, and to contain active elements programmable by the means of a programming language of sufficient flexibility. A reference implementation of the proposed system is included. The key aspects of the proposed system is that it should be universal, easily extensible and open for other potential virtual world creators. A CD included with the thesis contains source codes and translated executables of the program, with a simple sample database of a virtual world.

Web services support in the .NET framework
Fischer, Roman ; Buchalcevová, Alena (advisor) ; Máša, Michal (referee)
The work targets the very important part of service oriented architecture -- web services. It is focused at one of its practical implementation, from the Microsoft Corporation, especially in the last two releases of .NET Framework. The main target of this work is comprehensive summary and demonstration of Microsoft web services development. The principles of web services and their base in the .NET Framework are described here. At the beginning of this work the web services are put into the scope of service oriented architecture and their main principles are described. Subsequently the .NET Framework is explained with its main principles and with the comparison to the JAVA technology. This part is finished with the explanation of classic ASMX web services. The main part of this work focuses at detailed description of the theoretical and practical aspects of web services in the Windows Communication Foundation and the Windows Workflow Foundation context. Even the development of Windows Forms application is not left out, because they also have done a large progress and they are often consumers of web services. The options of securing web services in the .NET Framework are shown both theoretically and practically including authentication and authorization. The methods of transactional behavior are shown too. The work also focuses at the orchestration of web services including the explanation of workflows with the deployment example. At the end of the work there is revealed how to guarantee interoperability with other technologies, how to manage web services and how to ensure their versioning.
