The Study of the Contract Award in Business Company
Hladík, Pavel ; Stráník,, Rostislav (referee) ; Jurová, Marie (advisor)
The bachelor thesis deals with the issue of contract award in business company Falco computer, s.r.o., which is providing low-voltage sites services and operating other IT services. In my bachelor thesis, I focuse on the analyzing of current status of contract award, including all sub-processes, which take part in order processing. I have made an improvement proposal, based on the results, which may lead to optimalization of every process and cost reduction. I also define requirements of realization and it’s benefits.

Conceptual design of the reconstruction of an E.ON 22 kV distribution network installed at a specic area
Vepřek, Tomáš ; Nepevná, Vlastimila (referee) ; Blažek, Vladimír (advisor)
The aim of this thesis is a modification of the distribution network (DS) of the city of Brno to ensure power supply in the required quantity and quality for end consumers. Calculation of steady - state operation of distribution network (DS) of Brno is performed in the programme PAS DAISY Off-Line v.4.00 Bison. On the basis of available data (dispatching scheme, load current of stem lines and reserved power of wholesale customers) we will analyze the steady-state of network. We will find out which of the 110/22 kV transformer stations, cable and overhead lines are overloaded and perform network adjustments to ensure safe and reliable operation by 2015. We will identify in which year we will need to build a new power node in the northern part of Brno. The conclusion is focused on technical and economic evaluation of proposed alternative network arrangements.

Optical cabling - a comparison
Zelinková, Vlasta ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The thesis is focused on an analysis of mounting and cable laying fiber optic lines. The first chapter includes an analysis is made comparing parameters fiber and copper cabling, mainly in terms of access networks. This part specifies the various transmission media and access networks that are operated on them. Attention is focused on the transmission rate and its possible impact, provided the capacity and other important values. This section also demands site maintenance, service, or any failure on the routes of these networks. With this goal in the second chapter was created several designs networks that provide insight into possible solutions to the situation for emerging networks, and for upgrading existing networks, using both management and elements of optical and copper, or combinations thereof. Provide information from expert sources and verified directs the work of the future and to clarify further the eventual development of individual technologies. Most other space and offers the potential of optical technology, nature, and therefore the third chapter is fully devoted to only the transmission medium. At the beginning of this section is a theoretical analysis of possible ways of cable laying fiber optic cabling with a comparison of advantages and disadvantages. The most stable is an underground installation, which is costly in standard cases. As a result of these factors proved to be a possible solution using the underground installation of water pipeline shutdown. Therefore, the optical path designed, organized and implemented laying of fiber optic cable. By completing the inspection measurement and evaluation of the cost compared with other ways of installing fiber optic cable.

Electrical installations in apartment building
Novotný, Jan ; Formánek, Marian (referee) ; Doležalová, Jana (advisor)
This bachelor's thesis deals with electrical wiring in apartment building. The aim is to describe the types of distribution networks, implementation possibilities of service lines, describe the individual parts of the wiring in the building and the principles of their implementation. Further describe basic electrical materials and to explain the design of artificial lighting. In the practical part the information applied to a particular apartment building, together with the calculation of the estimated annual energy consumption of flats. For the apartment building project is created in the form of engineering report and drawings.

Panel meassurement device
Vaško, Pavel ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
The master thesis includes a literature search, which is focused on questions around panel measure instruments for measuring analog voltage signals. There is the block diagram and the concept of measuring voltage values designed from collected information and defined requirements to the device. In the next step a design of the circuit diagram is created and published and consequently transferred into PCB. The whole board has been fabricated, assembled and tested. The firmware development starts with the definition of basic functional blocks for using of internal elements of the device, which is followed by the implementation of the Modbus slave station service routine. The top part presents graphical user interface on the device.

Controlled lighting and shading in smart house
Novák, Michael ; Morávek, Jan (referee) ; Bátora, Branislav (advisor)
This bachelor‘s thesis is focused on controlling lighting and shading in a smart house. Lighting control covers switching and dimming mechanisms. This thesis presents dimming options for different types of light sources. Following this is an overview of shading devices and system wiring, often called smart wiring. Specifically, the thesis focuses on the Foxtrot system from Teco a.s.. This work describes the sensors and actuators used for switching, dimming and shading control devices. New library of functional blocks for lighting and shading control for Foxtrot system was created, for they were not included in any standard library. All functional blocks that have use in the control of lighting or shading - including standard ones - are described in this work.

Electrical installation in family house
Tesař, Jan ; Procházka, Petr (referee) ; Ondrejček, Vladimír (advisor)
This Bachelor Thesis is concerned with the design of the electrical installation of a family house. There are two main parts of the thesis – theoretical basis and the main design. In the theoretical part the reader is at first introduced to a powerline section, in which the electrical installation from the powergrid to a terminal equipment is described. Next part is about a low voltage wiring, where the commonly used types of wiring and devices are described. In the third part the reader can read about a lightning protection and its inner and outer parts. The main design consist of situational designs of devices and wiring in the house, switchboard designs, revision of the electrical protection and the technical report.

House wiring
Tománek, Drahomír ; Dohnal, Petr (referee) ; Valenta, Jiří (advisor)
The aim of this work is to gather requirements for wiring in a family house and then a real project for a family home. The theoretical part is divided into four parts. The first section lists the most important wiring standards. The second part deals with the different parts of the wiring by connecting electricity to the lighting and socket circuits. The third part concentrates on the protection against electric shock and on the overload protection. The fourth part focuses on the individual requirements of each room. The practical part consists of drawings, technical reports, A price quotation and control requirements regarding the corresponding technical norms. The designs include site plan of the appliances, wiring and installation of the switchboards.
