Numerical Analysis of the Lightning on Small Aircraft
Krutílek, David
This paper deals with numerical analysis of lightning stroke effects on aircraft. Computations are implemented by the use of the time-domain solver (FIT). Attention is turned to a simple model of a composite nose part of the airplane EV-55. The analysis of the model itself is performed for two fundamentally different basic conceptions of a possible protection against direct effects of lightning.

Indicator of Thunderstorm
Studený, Pavel ; Sekora, Jiří (referee) ; Chmelař, Milan (advisor)
The aim of this Bachelor thesis is a theoretical analysis of thunderstorms, lightning and their detection. The theoretical description then gradually moving towards designing their own detector. The detector will operate so that when a lightning activity captures pulses which generate lightning. Lightning will register using the attached counter. After the storm could be due to information from the counters to evaluate how strong the storm was.

Influence of hazardous EM fields on large objects
Klučka, Jaroslav ; Kovács, Peter (referee) ; Řezníček, Zdeněk (advisor)
This bachelor thesis deals with simulation of influences of electromagnetic field on an aircraft via computer program PAM-CEM. The aim of the simulation is verification of conditions for placing equipment and cables in chosen places. There were chosen two outer interfering electromagnetic fields: High Intensity Radiated Fields HIRF and a lightning bolt. During the simulation of HIRF, the plane was radiated by outer electromagnetic field. The decomposition of inner electromagnetic field was monitored during the exposure. Then, the electrical intensity was measured in three places, where the location of susceptible electronical devices was predicted. During the simulation of lightning bolt only indirect effects were taken into consideration. Current impulse was implemented into the skin of the aircraft and the decomposition of surface current was monitored.

The desingn of the lighting protection for civil buildings
Šebesta, Ondřej ; Bátora, Branislav (referee) ; Toman, Petr (advisor)
This thesis focuses on the issue of lightning protection and goes along with ČSN EN 62 305 norms. First part goes into effects of lightning on objects and engineering networks in theory. Second part familiarizes external lightning protection and possibilities of its realization. The issues of internal protection against lightning and surge protection are analysed afterwards. Second half familiarizes protected family house and the risks are calculated for this house. External protection is designed and verified by protective angle and rolling sphere methods. Last part of this thesis focuses on internal surge protection and individual levels of surge protection are designed.

Application of overvoltage protection in LV networks
Knebl, Jan ; Novotný, Jan (referee) ; Bátora, Branislav (advisor)
This paper describes the design of surge protection for objects of civil construction. The aim of this paper is to acquaint the reader with the problems of this region, which is nowadays especially for houses neglected. The introductory part of the thesis is focused on the theoretical analysis of the problem and become familiar with the standards in force, without which a person moving in this field certainly can not do. In the first major section is a repartition surge in general terms. In the second chapter, a repartition of surge protection on the inside and outside and a description of the individual components of these protections. The third chapter is made complete design protection for the school building, the first step is an analysis of the risks to unprotected building, then the protected and ultimately design of internal and external surge protection. In the last chapter, a check is made of the risk analysis using DEHN Support.

Energy-efficient guest house in the city of Lednice
Joch, Tomáš ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
My Masters project is titled Energy-efficient guest house in the city of Lednice. The assignment is to design a building, which meets contemporary standards of energy efficiency. There are three parts of the project. The first part consists of designing the structure of the building. The building is L-shaped with pitched roof, single-storey with attic. There is a pool with sauna, restaurant with kitchen and main hall with entrance and reception on the ground floor. At the attic there are twenty two dwelling units for guests, common room and staff facilities. The main entrance is oriented towards east. The building is masonry system from sand-lime blocks with prefabricated reinforced concrete floor slabs and roof is made of timber roof truss. The building facade is insulated by ETICS. In the second part, there are designed HVAC, lightning and shading, rainwater usage and photovoltaic power station. In the third, there is a calculation of energy need for heating and cooling using monthly balance mehtod. The project is designed with support of AutoCAD, Revit and DEKsoftT softwares.

Family House
Jakubčánin, Marek ; Selníková, Klára (referee) ; Klimešová, Jarmila (advisor)
The topic of this bachelor's thesis is realization projection of a family house located in village Stráţa. The house has a partial basement and consists of a living area as well as of an operational area designed for a dentist ambulance. The object contains parking slots for four cars and one parking space in garage, which is situated in the basement of living area of the house. The ground plan of the house has mostly rectangular shape with flat roof. The building is planned to be situated on slightly sloping terrain. The entrace to the dentist's ambulance is situated on the north side and the entrance to the living area of the house is located on the east side. The skeleton of the building will be constructed from the YTONG system.

VC5 and Vision Designer platform visual system
Popovský, Pavel ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
For the purpose of an future machine vision system development in Tyco Electronics Czech s.r.o. I have developed Cognex Designer template. Template will serve as a flexible basis for further development of camera applications on the Cognex VC5 industrial computer. The functionality of the program template has been successfully verified by modifying it to a particular application of the laboratory manual station used to measure the parameters of the manufactured connectors. A camera with lens and lightning was chosen and installed on the station. DIO communication was put into operation between VC5 and PLC system. The application has been calibrated and verified as a measurement system using MSA Type I and Capability study standard methods.

Design of a new ion counter for the nature environment
Roubal, Šimon ; Szabó, Zoltán (referee) ; Roubal, Zdeněk (advisor)
Subject of this bachelors thesis is an realization of new control board for iontmeter that is developed at UTEE. Iontmeter must be capable of fully autonomous measure in outside contitions. That means it has to be able to run on batery for a long time and has to be to resist outside weather conditions. Measured data will be saved on an SD card and also sent using GSM network to the IoT server.
