Optical cables in modern data centres
Hejtmánek, Ondřej ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The essence of this study was to evaluate the issue of fiber optic and data cables in modern data centers. To compare and evaluate optimal design parameters were chosen as follows: Performance, reliability, installation time, flexibility, weight and size, requirements maintenance and training and the total price. The introductory chapters describes structure of the data center and network bases and storage technologies used in data centers. Particularly a local area network Ethernet and storage technology, DAS, SAN and SAS. Followed by a metallic and fiber optic cabling. For metallic cabling are used primarily PiMF cables. The fiber optic cabling emphasis was placed on multimode fiber OM3 and OM4. The main point of this study was to compare three types of installation metallic and three types of fiber optic cabling. MRJ-21 solution, pre-terminated system and standard installation of the so-called notch technique for metallic cables. For optical cabling has been chosen MPO solution, pre-terminated system and standard installation by welding fibers. In the end were compared and evaluated various solutions. The main focus was placed on the parameters of performance, reliability and installation time. The optical systems were rated the best solution MPO and preterminated system. Results were similar for the metallic cabling, where most of the parameters of the solution satisfies MRJ-21 followed by pre-terminated system. Standard installation for both types of cables in data centers too has not worked. All types of installations have been tested in practice and measured at different times during install.

Data centre project - structured cabling
Hejtmánek, Ondřej ; Dostál, Otto (referee) ; Filka, Miloslav (advisor)
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.

Drawing funds from the European Union by Czech businesses
Červenková, Iva ; Potluka, Oto (advisor) ; Machálek, Emil (referee)
This bachelor thesis deals with the use of financial resources from the European Union by the Czech business companies. In the theoretical section is defined the concepts of regional policy, its targets for the period 2007-2013 and the Structural Funds. Specifically, it focuses on the Operational Programme Enterprise and Innovations. The practical part is based on questionnaire research. The questionnaire was sent to Czech companies which draw from the Operational Programme Enterprise and Innovations. The goal was to find answers to the following questions: what is the business information on option grants, what is the difficulty of the grant application process and the problems that businesses face.

Coordination of activities leading to trade fair execution (selected problems)
Dědečková, Jana ; Filipová, Alena (advisor) ; Zeman, Jiří (referee)
Bachelor thesis deals with state support of participation in trade fairs; the key role has a project manager representing Ministry of Industry and Trade of the Czech Republic. He coordinates activities of others participants of the common exposition. First chapter solves the question of trade fairs, their trends and the state support of participation in fairs in general. The second chapter is devoted to the work of the project manager and the processes he adheres to while organizing the participation. His work is in practice demonstrated on concrete fair MACEF Milano 2009 in the third chapter. The effectiveness of the official participation in trade fairs and the work of the project manager are evaluated in conclusion of the thesis.
