Conversion of the road I/52 to motorway D52
Sejkora, Jan ; Nykodym, Jakub (referee) ; Všetečka, Martin (advisor)
The aim of the diploma thesis is to propose a modification of the road I / 52 between the junction with the D1 motorway and Rajhrad on the D52 motorway in a way that a continuous highway can be created without the need to create an alternative route over the southern tangent in route Wien-Prague and D2 and also to design routes for transport which cannot enter the highway. The other aim is to define the problem elements and create a variant solution.

II/494 Vrbětice-Slavičín
Kuric, Filip ; Nykodym, Jakub (referee) ; Kosňovský, Michal (advisor)
The bachelor’s thesis deals with the modification of the road II/494 between Vrbětice and Slavičín in the form of a technical study. The thesis solves the modification of the road in two proposed variants. Variant A is processed as a road reconstruction in the existing longitudinal alignment. Option B solves new construction in a new corridor. The reason for modifying the communication is to design a more suitable longitudal and vertical alignment of the route in accordance with a valid standard in order to increase comfort and safety on the route. The subject of the thesis is also comparison of suggested variants.

Editing road II / 497 Uherské Hradiště - Bílovice
Sáček, Marek ; Nykodým, Jakub (referee) ; Kosňovský, Michal (advisor)
The topic of the master’s thesis is an alteration of horizontal and vertical alignment of the road II/497. Designed section of the road is situated between municipality of Uherské Hradiště and municipality of Bílovice. The reasons for this alteration are insufficient parameters of current condition of the road. The proposed alteration includes adjustments of related crossroads and bus stops, which are located in the selected area.

The influence of operating parameters and construction parameters of the low-NOx burner on characteristic parameters of combustion processes
Nykodým, Jiří ; Hudák, Igor (referee) ; Bělohradský, Petr (advisor)
The main aim of the work was the investigation of the effect of operational parameters of the combustion process (combustion air excess, primary fuel ratio) and burner constructional parameters (the pitch angle of secondary nozzles, tangential orientation of secondary nozzles towards the axis of the burner) on the formation of NOx and CO, flue gas temperature, the shape, dimensions and stability of the flame, in-flame temperatures in the horizontal symmetry plane of the combustion chamber and the amount of heat extracted from the hot combustion gases in the combustion chamber’s shell. Experimental activities were carried out in the laboratory of the Institute of Process and Environmental Engineering, which is focused on burners testing. The combustion tests were performed with the experimental low-NOx type burner, namely the two-gas-staged burner. Mathematical model developed based on the experimental data describes the dependency of NOx on the operating parameters of the combustion process and burner constructional parameters. The model shows that increasing air excess and increasing angle of tangential orientation of the secondary nozzles reduce the formation of NOx. The temperature peaks in the horizontal symmetry plane of the combustion chamber decreases with increasing combustion air excess. The thermal load to the combustion chamber’s wall along the length of the flame was evaluated for selected settings. It was validated that the thermal efficiency of is reduced when higher air excess is used.

Cleaving machines
Nykodým, Jiří ; Jonák, Martin (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor thesis deals with the study currently being produced by major semi-automatic and automatic cutting machines. The main aim of this work is to compare the individual properties of machines that appear on the market today. Especially comparing their individual parameters, characteristic for each manufacturer and each type of splitting machines, such as cutting speed, mobility, durability, cutting, etc..

The Population Protection against Floods in the Town of Ústí nad Orlicí
Ruhásová, Aranka ; Hradil, Jaroslav (referee) ; Nykodým, Josef (advisor)
This bachelor thesis deals with the topic of population protection against floods. In the thesis are explained the basic terms of this topic, the equipment used in protection against flooding, flood authorities and law both in the CR and the EU. Work includes further description of the programs on flood modeling and risk analysis. Another part is devoted to the assessment of preparedness of the CR and the EU, evaluation of the previous flood of 1997, 2002 and 2006. In the last chapter all of information obtained are applied on the place of interest and assessed the readiness and the ability to improve the situation in flood protection.

Baroreflex sensitivity and heart rate
Halámek, Josef ; Jurák, Pavel ; Swenne, C. A. ; Kára, T. ; Souček, M. ; Eisenberg, M. ; Nykodým, J.
The correlation between baroreflex sensitivity (BRS) and heart rate (HR) is discussed. According to theoretical model, where the constant blood flow is supposed, the BRS given in [ms/mmHg] must correlate with HR and BRS in [mHz/mmHg] should not correlate with HR. This assumption was confirmed by the measurement on healthy young subjects, but it is not valid for old healthy subjects and for patients.

Porovnání metod pro výpočet srdečního výdeje ze signálu impedanční kardiografie
Jurák, Pavel ; Halámek, Josef ; Vondra, Vlastimil ; Kára, T. ; Nykodým, J. ; Číp, Ondřej ; Eisenberger, M. ; Leinveber, P. ; Fráňa, P. ; Meluzín, J. ; Souček, M.
The goal of the study is to compare various methods of non-invasive stroke volume (SV) assessment from a raw impedance cardiography (IC) signal. IC detects changes in cardiac haemodynamic function using thoracic electrical bioimpedance technology. Corresponding changes of impedance are used along with ECG and blood pressure to measure and calculate haemodynamics parameters
