The work deals with the developmental stages (Releases) of the third generation UMTS net-works. It explains a partial improvement from Release 99 to Release 5 and Release 6 to im-prove the quality parameters of a mobile data transmission. In the practical part, there are measured qualitative parameters of the third generation networks that are available in the Czech Republic: UMTS, HSDPA, CDMA 1xEV-DO Rev.0 and Rev.A and UMTS-TDD. The measurements give reasonably achievable data rates in both directions (downlink & uplunk), a response time, quality of VoIP calls, a dispersion, a data-loss and an ability to transmit video with different data flows. The other aspects especially an availability of coverage and end-user terminals have been assessed wihin the each network. The work is supplemeted with a laboratory, which is focused on a practical comparison of the basic parameters of data transmissions of 2G and 3G networks.

This Master’s thesis deals with project of blueprints for installation of data cabling in specific building following regulations. Theoretical part describes basic overview of used regulations and principles of data networks with focus on Ethernet and Wi-Fi standards. Separated chapters cover passive layer of data networks and computer-aided-design. Practical part contains implementational and architectural drawing of data network project in multipurpose building. According to these plans the project could be realized.

This master’s thesis is concerned with analysis of cabling and cabling systems in data center and with their projection as follows. The part of the work is aimed at the measurement parameters of metal cables which are used in data center with noise. The first part is focused on analyzing the structure of the data center and cabling used in it. The structure of the data center is based on the TIA-942 and consists of an entrance room, main distribution area MDA, horizontal distribution area HDA , zone distribution area ZDA and the equipment distribution area EDA. Divided into backbone cabling and horizontal cabling and use standard and pre-terminated cabling. The measurement results of structured metal cabling with noise are discussed in the next part. There were used these types of cables UTP, FTP and S/FTP. The measurement was performed in the electricity substation and in the laboratory of electromagnetic compatibility. The third part of this work deals with the actual design of structured cabling for the data center. In the first design we use the standard installation, the second preterminated cabling. For both types of installation cost statement is processed (CAPEX). Thesis is also completed with DC design drawings and rack drawings.

This Diploma Thesis deals with analysis of the current processes in small software company. On the basis of the weakness evaluation, the new extensions of the information system are designed. The first extension is new module for on-line sale and cashless on-line payment. The second one is integration of Business Intelligence tools to help streamline marketing strategies of this company.

The thesis is focused on issues of information systems, evaluates advantages, disadvantages and possible risk coming from implementation of IS. In theoretical part are the main issue ERP systems, its history and modern trends in this field. It aims also on the analytical tools business intelligence, which are helpful in the decision-making process creating future strategy of the company. In practical part the information system of Kermi will be evaluated by using analytical methods HOS 8 and Zefis. With the help of both tools the problematic part of the information system will be found and then aim of this thesis will be elimination of these problems.

I have chosen this topic of my paper, because I have been working in Divadlo Husa na provázku as a network administrator. The every day problems I have been contending with should be eliminated by this project as well as it can bring some new pleasant function in whole computer infrastructure. In theoretical part of my paper I will engage in information systems in general and it’s analyse. In a practical part of my paper I will use HOS 8 analyse for evaluation of current IS. After this analyse some variation of improvement will be introduced. In final part of this paper will be the financial calculation of suggested solutions included.

The aim of this work is to design data center placed into an ISO container used for transportation. Maximization of the space efficiency and minimization of the running costs are primary. This work also contains a measurement of data center electronic parts power consumption, a computational fluid dynamics model, a simulation of external thermal gains and a 3D model with basic technical drawings.

This master's thesis deals with knowledge discovery and is focused on data stream classification. Three ensemble classification methods are described here. These methods are implemented in practical part of this thesis and are included in the classification system. Extensive measurements and experimentation were used for method analysis and comparison. Implemented methods were then integrated into Malware analysis system. At the conclusion are presented obtained results.

This Master Thesis deals with the design of part of ICT infrastructure migration of two sites of the international company to the external data center. It analyzes the current status of company ICT, describes the virtualization infrastructure and its operational costs. Main part of the Thesis describes a possible solution of migration of virtualization infrastructure to external data center by using project management tools and methods. Finally, the Thesis summarizes project benefits for the company.

This diploma thesis deals with the design of eight-bit digital to analog coverter with fully differential outputs in technology I3T25 of ON Semiconductor company. The work contains the description of basic structures and characteristics of digital to analog converters. The main focus of the work is to design a converter and auxiliary circuits at the transistor level. The functionality of designed circuits is verified by simulation environment Cadence.
