Position indikator behind the wall
Slavíček, Radek ; Friedl, Martin (referee) ; Szabó, Zoltán (advisor)
This bachelor´s thesis is focused on explaining of basics of electromagnetism and principles of resonant circuits. These solutions are used for design the indicator opposite position. The next step of document is solution by using magnetic field for design of transmitter and receiver antennas for electronics devices. The final products are solved as the best way for the design. Development process is described step by step in individual chapters.

UWB Automated Testing Tool
Charvát, Jan ; Juráň, Radovan (referee) ; Mlýnek, Petr (advisor)
This thesis deals with the process of automating the testing of wireless locators. These devices use the UWB system, which is introduced in the theoretical part of this thesis. Furthermore, the topic of the testing process and the possibilities of its automation are discussed. The practical part of this thesis is devoted to the design and construction of an automated test fixture for UWB locators, both hardware and software part.

Impact of cross-country double earth faults on voltage condition in LV networks
Fojtášek, Jan ; Vyčítal, Václav (referee) ; Topolánek, David (advisor)
This master's thesis is focused on the influence of double earth fault on voltage ratios in the compensated network. This thesis is focuses on, in particular on the analysis of voltage ratios on the secondary sides of distribution transformers when this non-local fault occurs. The compensation of the non-local double earth fault using the symmetrical components method is performed and the performance of this method is verified. The analysis of the effect of double earth fault on the proposed power system is carried out in PSCAD software and further evaluated. This type of non-local fault is investigated while modifying the various parameters of the designed system. To differentiate the double earth fault from the two phase ground fault, the asymmetry on the LV sides of the distribution transformers is investigated. A locator is provided to locate the location of the double earth fault and the two-phase ground fault, which, combined with the asymmetry values, is able to determine both the location of the fault and the differentiation of the co-located fault from the non-co-located fault.

Business plan
Doan, Manh Hung ; Srpová, Jitka (advisor) ; Doan, Jan (referee)
Firstly, the aim of this Bachelors thesis is to create a business plan for unification of Vietnamese minimarkets in the Czech Republic by a web application. The goal of the unification is to create a shopping union and then a retail chain. Secondly, it is necessary to define conditions for successful realization and to answer research questions. After the introduction, two main parts of the work follow. The theoretical part deals with the definition of basic concepts in the business, the key legal forms of the company and all the necessary points which are needed for making a business plan. The second part is a practical application of theoretical knowledge and contains a real business plan to create a locator of Vietnamese minimarkets. In the business plan, the main focus is on the creation of a viable business, a description of the business opportunities, the objectives of the company and the owners, the company strategy, the market analysis, the marketing strategy, the implementation plan, the identification of the risks, etc. The ending of the Bachelors thesis contains answers to the research questions and summarizes the conditions of the successful realization of the business.

LISP - The separation of network node's locator and identifier
Šubrt, Ondřej ; Pavlíček, Luboš (advisor) ; Matuška, Miroslav (referee)
The purpose of this paper is to describe the features and functionality of LISP protocol (Locator / ID Separation Protocol), its possible use in the network infrastructure and description of the requirements necessary for its successful implementation. Part of this thesis is also the setting of modules to support the network protocol on FreeBSD and then connecting the station to the experimental network, operated by Cisco Systems. The reachability of the test station in the experimental network is verified by station within the network and by server from the internet. LISP implementation on FreeBSD is called OpenLISP and has fully integrated support for encapsulation and decapsulation of datagrams. It also includes the implementation of the mapping cache and mapping database. For connection to Map Server is used OpenLISP Control Plane implementation by Guruprasad K. Rao and LIP6. The paper is based on the draft implementation of this protocol and its individual parts placed on the website of the Internet Engineering Task Force organization. The functionality of the protocol, described in this paper, is valid by March 2012.
