Harness tester
Smola, Tomáš ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
This thesis deals with issue and construction of wire harness tester. In the first place, is this thesis focused on market exploration and comparison of comercial testers with concrete requirements for small batch production. I will try to find a suitable product in worldwide market, which would be convenient for company producing construction machinery. For testing switchboard harness we need to test interconnections between connectors, resistors, relays, diodes, transils and switches in the dashboard. If I can not find some product, I will try to design some new tester. My priorities will be testing all components in harness, maximum flexibility of tester for the future trends in contruction of rollers and user friendly control.

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.

Field strength measurement
Novák, Tomáš ; Dřínovský, Jiří (referee) ; Nováček, Zdeněk (advisor)
This thesis is focused on problems of measurement of field intensity especially in short-wave zone of received frequencies. To measure the intensity of electric field, it is necessary to use a suitable antenna whose properties and characteristics/parametres meet best the requirements of this measurement. These requirements are analysed/discussed in the introductory part of this thesis. From these requirements resulted one specific solution which is applicable to this problems. This solution is frame antenna which meets /matches best the requirements of this measurement. Furthermore, a complete suggestion for the frame antenna as well as its calculations were discussed. From individually calculated results graphical functionalities were set together that provided the bases for selection of suitable parameters for frame antenna. Then these bases were verified with similar antenna that was available. In second part of this thesis we modified standard antenna modul RFT FMA11 so that there would be a possibility to use it with any selective microvoltmeter.

Diagnostic and improvement of electrical contact
Hrdý, Branislav ; Kuchyňková, Hana (referee) ; Veselka, František (advisor)
The aim of bachelor thesis is create a summary overview of terminals, to obtain information about contruction, materials of the conductive parts of the terminals and its snap methods. The next goal was description of methods of conductors’ construction and snap methods of its con-ductors. All processed information is obtained from the technical literature and from practical knowledge acquired during the measurement and monitoring of analyzed terminals. The final goal was to create an animated 3D model of terminal as a sample of main process of terminals’ working principle. In conclusion of this work is comparison of terminals, and their properties, facts observed during measurement or testing.

Analysis of the Usual Time of a Driver Observing Specific Objects
Fujačková, Hedvika ; Semela, Marek (referee) ; Bucsuházy, Kateřina (advisor)
This diploma thesis focuses on drivers of motor vehicles and the usual time they spend by specific objects. The theoretical part of the thesis brings an overview of literature on human perception. The eye-tracker is defined here as the instrument used for scanning the movements of the drivers eyes, here are also named its types and its applications in various fields of life. Finally, this part deals with the advertisements placed alongside roads acting as distractive elements. The experimental part builds upon the collected video recordings and offers an analysis of drivers’ observations of outdoor advertisements that attract their attention, mainly billboards.

Design of the distribution network branch for new family and apartment houses in Újezd u Brna
Frechová, Lucie ; Novák, Vojtěch (referee) ; Ptáček, Michal (advisor)
The work mentions the concept of present electricity networks in the Czech Republic and based on voltage levels it also describes distribution networks in more detail. Furthermore it brings the analysis of legislative conditions and technical aspects, under the rules of the distribution network operation, for new customers who require new connection to electricity network. Because of the steady-state network evaluation represents very important issue of the power system calculations, therefore it is explained in theoretical part of this work. Nowadays, Gauss-Seidel method and Newton iterative method are generally used for the steady-state analysis. Mentioned ones are also described and compared together in theoretical part. Furthermore methods are applied in practical part which solves specific configuration of the network in a given area. Moreover there are the basics of the conductor sizing in terms of the warming, both during normal operation and during a short circuit. However, it is necessary to respect other aspects of the conductor sizing, therefore issues of mechanical and electrical strength, the voltage drop and the sizing economy are also shown. There is also the characteristic of proposed and the description of the individual components which are used for the network i.e. transformation station, HV and LV switchgear, transformer, HV and LV cabling. It also concludes the characteristics of the design opportunity with their power and economical comparison.

Cable harness tester
Valenta, Jakub ; Valach, Soběslav (referee) ; Burian, František (advisor)
This semestral paper deals with the issues of testing and requirements examinations for cables and cable harnesses. These terms are defined in the work and the difference in their meaning is described. The work also describes the characteristic features of cables and cable harnesses, explains their importance and focuses in more detail on the variable properties that may change over time or that are dependent on manufacturing errors. The principles and procedures of tests of these properties are covered in the work and are the essence of the subsequent practical part. In this part, the work deals with the design of the measuring circuit prototype for testing of the insulation resistance of cables and their desired continuity in bundles. This design is then physically implemented, the processes of designing and implementing are described in detail and finally its functionality is tested and presented to the reader.

Electrical installation in family house
Dalecký, Jan ; Červinka, Dalibor (referee) ; Ondrejček, Vladimír (advisor)
In this bachelor's thesis is analyzed electrical installation of family house. It's goal is to summarize information important for designing electrical installation and subsequently create project documentation of electrical installation of three-floor family house. First part of the bachelor's thesis is dedicated to directives and demands for realization of electrical installation, which you need to lead by when creating project documentation and then assembling it in an object. The second part is focused on creating blueprints including lightning protection, low and high current installation, designing and dimensioning switchboards and technical report.

Driver State Monitoring
Blašková, Barbora ; Prustoměrský, Milan (referee) ; Chudý, Peter (advisor)
Vedieť šoférovať auto je v dnešnom svete považované za dôležité, či dokonca nutné. Avšak, s pribúdajúcou premávkou je nevyhnutné, že sa stanú nehody, ktoré môžu mať aj fatálne následky. Množstvo informácií, ktoré musí vodič vedieť spracovať sa neustále zvyšuje a s tým aj stresové situácie, počas ktorých vodič nemusí vedieť racionálne uvažovať. Táto práca sa zameriava na nájdenie techník a postupov ako implementovať monitor, ktorý by predikoval level stresu vodiča počas jazdy, aby sa predišlo takýmto nehodám.V práci boli implementované dva typy modelov - osobný a všeobecný. Oba využívali fyziologické dáta spolu s kinematickými, ktoré boli nahrané počas jazdy. Oba modely boli schopé predpovedať úroveň stresu s vysokou pravdepodobnosťou.
