Optimum layout of workplaces security checks of passengers
Bordovský, Lukáš ; Janík, Radomír (referee) ; Šplíchal, Miroslav (advisor)
The final master’s thesis analyzes the individual elements of Security control workplace and solves their optimization with respect to the rulemaking side of things, and integration into the existing space layout with a vision of the increasing demand for transport. Solves the issue of electromagnetic interference elimination in the detection equipment and suggests possible solutions to overcome them. The work is primarily related to the Prague - Ruzyne airport.

Evaluation of LED replacements
Bordovský, Lukáš ; Pavelka, Tomáš (referee) ; Škoda, Jan (advisor)
The aim of my thesis is to become familiar with LED replacements of light sources, possible problems, advantages and disadvantages. In the work are at first explained terms of light technology. Then are concisely described actual light sources, that can be replaced by LED. That concern: classic bulbs, halogen bulbs, linear fluorescents and compact bulbs. After that is described principle of LED light fittings and advantages, disadvantages nowadays to use LED light fittings. The main emphasis is placed on chapter 5. The compensations of linear fluorescents by LED moduls. The following chapters are dedicated to comparison of fluorescent lamps and LED moduls. Involving-photometrics parameters, luminous intensity, lumniance analysis and also economics comparison of lighting systems with fluorescent lamps versus the LED moduls.

The calculation of the short circuits of the given network
Bordovský, Lukáš ; Paar, Martin (referee) ; Toman, Petr (advisor)
The main aim of this Bachelor thesis is to introduce you a calculation of short-circuit rates in compliance with IEC 60909, and a subsequent calculation of a scheduled real network. The thesis itself is divided into two parts : a theory about the short-circuit problems and a simple model example are stated in the first part, in the second part is stated the calculation of the given real network for the case of an occurence of shunt faults at distribution points, namely a three-phase fault, a two-phase isolated fault, a double-phase-to-earth fault and a single phase fault. The work is coupled with a determination of current and voltage rates at points P and K. At the point P is situated distance protection relay and at the point K comes the shunt fault. The calculations are done with a method of successive simplification.
