Mechanisms of QoS assurance in fixed, wireless and mobile data networks
Václavek, Radovan ; Novotný, Vít (referee) ; Molnár, Karol (advisor)
This bachelor´s thesis deals with mapping technologies and base parameters used to guarantee the quality of systems in the local area networks, including wireless and mobile ones. I have focused mainly on requests and classifications, which are typical for the types of networks on link layer. In Ethernet I focused on the gradual trends in the fore mentioned technologies and IEEE 802.1Q and connected IEEE 802.1p standards included. The next part describes the quality of systems in wireless nets in different types of environments and again uses given standards for quality of systems guarantee in 802.11e and connected 802.11a/b/g standards. The next part focuses on the latest generations of mobile nets, looking at the types and trends of the latest technologies. Here I draw from standard project 3GPP, which describes the problems with these technological developments. The next part focuses on WiMAX technologies. In the penultimate paragraph, the constituent network technologies are compared from the view of securing QoS and I propound possible ways of securing coversion of constituent technologies. The conclusion summarises all the technologies I have mentioned and the future trends including possible problems and challenges with these latest technologies.

Line protection against overload and short circuit
Konšel, Ladislav ; Vaněk, Jaromír (referee) ; Valenta, Jiří (advisor)
This work includes a theoretical treatise on the operation of electrical wiring for the overload and short circuit. This is mainly on thermal effects of over current and their influence on the properties of conductors and insulation. Work Includes links to determine the load current, depending on the properties of leadership and its surroundings. It also deals with the protection of conductors against overload and short circuit. The work includes measurements process of warming wires. Practical project of proposal circuit is created using SICHR. The project includes proposals of conductor’s sizes and safety components for both residential building and individual flats.

Valuation of Small-Scale Public Contracts
Kulich, Jan ; Srba, Martin (referee) ; Hromádka, Vít (advisor)
The bachelor thesis is dealing with small-scale public contracts of building works. It is examining the methods of instructions and contender's evaluation of specific public contract. Firstly the work describes theoretical part of public contracts, their division, terms and definitions, that reader was informed in the second part of bachelor thesis. This one is examining specific public contract. There is also evaluated method of instruction used evaluation criteria and next is designed own method of instruction and evaluation criteria. The result of the practical part is comparison of methods of instructions specific public contract of building works.

Risk analysis in conformity assesment process
Možný, Radek ; Teš, Vasilij (referee) ; Koška, Petr (advisor)
When presenting a product within the so-called regulated sphere the producer is obliged to keep to the given legal liabilities of the technical product requirements and the governmental regulations concerned. The producer is also to carry out an analysis of the technical requirements and specifications of the product. Subsequently, the producer also has to provide the technical specifications and documentation for preparation of ES declaration, guaranteeing that the product fulfills the CE requirements. The task is to design and set up documentation for the ES declaration for Polymount printer cleaning machines PPC mini, PPC M2, PPC L2 and PPC XL2.

Management of Building Order from Aspect of Supplier
Vajbarová, Eliška ; Nový,, Martin (referee) ; Waldhans, Miloš (advisor)
Construction order is an essential production unit of a building company. Managing the order in a building company focuses on processing offers, productive preparation and realisation of construction works. The practical part of this thesis describes and examines the management of orders in two construction companies, whose production is oriented toward realisation of ground-based buildings. The result of this thesis is a comparison of these two companies, the lay-out of standard forms and their implementation into agency of the companies to improve their preparation and realisation of the order.
