Audit of ageing management in plants at major accident hazard
Juráňová, Bára ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
This diploma thesis is focused on raising awareness of the phenomenon of ageing equipment. The aim was to analyse the current state of knowledge and to develop an ageing management audit method for the Czech Republic. The method was applied in a company located in the Zlín region. In the conclusion of the thesis, specific measures are formulated that the company should pay attention to.

Casuistry of major accidents in the Czech Republic
Rozlílková, Lada ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
This Master’s thesis deals with the topic of major industrial accidentsin the Czech republic. The main objective of why accidents are reported and investigated is to provide information to other companies to learn from these significant events, reduce the risk of such events in the future and prevent damage to human and animal life and health, the enviroment and property.

Reduction of risks of explosive atmospheres in coating plants
Lužný, Jan ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
Bachelor’s thesis deals with conditions of explosion, areas with danger of an explosion and their division into individual zones. Furthermore the thesis is focused to options for a reduction of risks of explosion and takes into account the coating plants by using primary, secondary and constructional prevention. It describes the recommendations and options for reduction of the explosion creation, eventually its results.

Safety of automated industrial valves in operating conditions
Kryštof, Ondřej ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
Choosing suitable and safe valve with accessories depends on general specifications for plant. Using valve for on/off, throttling, back-flow prevention, etc., pressure drop is related with Kv value or leakages from piping systems are main factors for properly valve selection. Valve have to resist chemicals and substances that may change the state, temperature and its fluctuation, pressure, corrosion and erosion. This properties determine pressure class, temperature resistance, connection into pipe and sealing material as gland packing, seats, seal between flange etc. This and other specification, listed in this thesis, can help determine suitable type of valve. This thesis deals construction design of valve and accessories as well. The last chapters are focused on calculation of safety valve and selection safe and appropriate control valve with accessories.

Safety audit in a plant for the preparation of concrete
Palička, David ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
In this thesis I focus on a safety audit in a plant for the preparation of concrete carried out according to Self-Audit Handbook for SMEs. In the first part some examples of accidents in plants for the preparation of concrete in Czech Republic as well as in abroad are stated. In the second part I describe the subject of work injury in Czech Republic and the obligations of employees and employers in accordance with the labour code. The third part deals with the safety management, occupational health and safety management system and briefly covers various types of audits. The next part analyses briefly concrete composition and its production process, the function of plant for the preparation of concrete and safety requirements demanded from the plant for the preparation of concrete in accordance with an appropriate standard. The last part describes the audit itself processed according to Self-Audit Handbook for SMEs at two plants. The aim of this thesis is to process and to evaluate results of two audits that took place at plans for preparation of the concrete and to propose corrective actions and process improvements.

Improving the parameters of the prototype of self-loading water sweeper superstructure
Vraspír, Kamil ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
This thesis explores development stages of a Self-loading water sweeper superstructure prototype. The theoretical part describes thoroughfares in terms of pollution, various types of cleaning machines currently in use and a detailed description of the FMEA method, which was used for identification of potential failure modes and risk mitigation. Stages of measurement and superstructure parameter improvement are proposed, executed and described in the practical part. In these stages, creation of model documentation, verification of functionality and stage of analysis FMEA are included. Furthermore, this section describes the results of tests devised to validate key superstructure parameters. The result of the work is a functional Self-loading water sweeper superstructure prototype, confirmation of key superstructure functional parameters and a draft of a series of improvement measures aimed at eliminating potential risks associated with operation of the superstructure.

Precise measurement of the electron antineutrino oscillation
Pěč, Viktor ; Vorobel, Vít (advisor) ; Trávníček, Petr (referee) ; Vénos, Drahoslav (referee)
The Daya Bay experiment is designed to precisely measure short-baseline disappearance of reactor antineutrinos from reactor cores at the Daya Bay nuclear power plant complex in the Guangdong Province of China. It pre- sented the most precise measurements of oscillation parameters sin2 2θ13 = 0.084 ± 0.005 and |∆m2 ee| = (2.42 ± 0.11) × 10−3 eV2 . Background to the antineutrino signals is mainly created by cosmic muons and is effectively suppressed by use of water Cherenkov and RPC muon detectors. This thesis describe testing of RPC detectors prior to their installation at the experi- mental site. Part of the cosmic muons stop in the experiment's antineutrino detectors, and they decay or are captured by 12 C producing 12 B. Isotope 12 B contribute to accidental background. Rates of muon decays in the detectors are estimated in the thesis. The experiment can register electron antineutri- nos from supernova with expected signals around 20 MeV. Energy scale of the detectors at 53 MeV is determined.

Analýza dlouhodobého vývoje jasu noční oblohy na Observatoři Pierre Augera
Podškubka, Radek ; Prouza, Michael (advisor) ; Trávníček, Petr (referee)
In this paper we compare night sky brightness at the Pierre Auger Observatory with the flux of the solar extreme UV radiation. The night sky brightness is measured for monitoring purposes during operation of fluorescence detectors. The data were processed several times under slightly different conditions that should exclude the impact of moonlight, artificial light pollution and cloudiness. If one does not consider the effects mentioned before, the main source of night sky brightness is an airglow. The goal is to show that night sky brightness correlates with the flux of solar extreme UV radiation, what will confirm that extreme UV radiation is the cause of the airglow origin.
