The Continuity Indicators Calculation of E-ON ČR Distribution Network Segment
Girga, Eduard ; Černý, Pavel (referee) ; Paar, Martin (advisor)
The aim of this master’s thesis is calculation and analysis of reliability indicators of the company E.ON Česká republika, s.r.o. distribution network in the south Moravia territory (area of former Jihomoravská energetika) for the period of one year, from 1st November 2008 to 31st October 2009. We consider events incurred on overhead or underground lines of level of high voltage or directly connected with these lines. Events originated from extensive disaster interruption of electric energy supply caused by particularly unfavourable external effects are not considered, because network components can not be efficiently dimensioned on those influences. Known aspects of the events are time of origin, time duration, place and cause of failure inception. Analysis of reliability indicators is accomplished according to different point of view. The first aspect is the hours of day, during which the event lasted. The second aspect is the hours of day, during which the event incurred. The third one focuses component pointed as reliable for the origin of the event. The last standpoint is percentage load of the line outlet, on which the event occurred. We can ordain this load as the proportion of current flowing through the line outlet in the time of event inception and of the value of maximum current set up on the protection of the line outlet. Indications mentioned in the last sentence were searched in the dispatcher centre thanks to graphical interface of application RIS JME Brno. In the theoretical part of the work there is described the structure of distribution network and its fundamental influence on the continuity of electric energy supply, the ways of evaluation and increasing of electric energy supply reliability, regulation of continuity of electric energy supply with emphasis on regulation in the Czech Republic valid until 26th February 2010 and since 27th February 2010. The last theoretical part focuses on definition of failure and differentiation of failures according to various aspects.

Static analysis of moving skyscraper
Jedlička, Michal ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The thesis is about static analysis of moving skyscraper (inspired by The Dynamic Tower). There is a rotation of each particular floor around its axis independently on each other. In this thesis, moving skyscraper is solved as a whole piece with specialization in the moving floors and their mounting on the core of the building.

Component design for Joomla editorial system
Ingr, Michal ; Lambertová, Petra (referee) ; Koutný, Martin (advisor)
The bachelor’s thesis describes the creation and implementation of component for the management of electronic library in the Joomla content management system. In the introduction, there are explain the basic concepts, such as what is a component or CMS. The rest of the work is focused on the creation of its own component. The final application allows user to execute basic operations such as adding and deleting records in the system. The entire application is programmed in PHP language with the use of certain internal Joomla content management system functions and interact with MySQL database. The main aim of this work is to create a free software, which can be further modify and extend.

Production of joint folded out the rule
Šoukal, Hynek ; Podaný, Kamil (referee) ; Žák, Ladislav (advisor)
Project developed within the bachelor study presents a proposal production technology of joint folded out the rule from construction steel 12 060. Thick is 0,5 mm and the production ran is specify at 30 000 units a year. In accordance with literature studies and by calculations have been designed a combined roll forming tool, which consists of a rack with two pillars. This tool will be fix in on eccentric press LEN 10C by SMERAL, Trnava, with nominal press force 100 kN. Trimming punches, holding punch and bending puch are made of tool steel, grade 19 436.3. Lower functional part of the tool ass well.

Simulation of cryptographic algorithms using FPGA
Németh, František ; Mašek, Jan (referee) ; Smékal, David (advisor)
Bachelor thesis is dealing with a cipher standard AES and with a design of encryption and decryption components for AES in special modes of operation. Programming language is VHDL. In theoretical part of thesis is a further descriptions of AES and behaviour of block cipher operation modes. Furthermore the brief description of VHDL, FPGA and NetCOPE framework is a piece of theoretical part as well. The practical part contains designs which are made in developing environment Vivado from Xilinx. Programmed modes of operation are ECB, CBC, CTR and CFB. Simulation outputs and synthesis results are summerized in tables.

Rent an apartment in Most, and the factors that influence them
Bartošová, Hana ; Weigel, Lubomír (referee) ; Uhlová, Eva (advisor)
The master's thesis deals with market research to determine the amount of the usual rent in Most and assessing factors that act on the rent. For market research are identifies four categories of flats, which are 1+1 and 1+kk, 2+1 and 2+kk, 3+1 and 3+kk, 4+1 and 4+kk and larger. On the basis of the obtained information are made maps which colour-illustrated apartments by price/month/m2.

Production of the "truss beam" component in a smaller engineering company
Šmerda, Michal ; Chladil, Josef (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis describes manufacturing of the "trussed beam" component in a small engineering company. This work is divided to several parts. The first part consists of theoretical points, which describes selected economic terms, terms about manufacturing and specific engineering technologies. Part two contains an analysis of the current state. In part three is created proposal solving, which including a product price calculation and proposal for streamlining production process and technological and economic evaluation.
