Electricity blackout study with regard to the nuclear power plant Dukovany
Žák, Jiří ; Fejta, Libor (referee) ; Radil, Lukáš (advisor)
The entire diploma thesis analyses causes, consequences and repercussions of an electricity grid network blackout and its impact to the respective consumers. Remarkable blackouts recorded since 1965 are briefly described and basic available information is considered. The grid standard fixing measures and electricity delivery priorities are characterized. The thesis also pays attention to entire Czech Republic grid availability and its blackout endurance as well as to its robustness within last several years. Indirect Fukushima event influence to the Czech Republic electricity system is mentioned. The main part of the thesis comprises of four big European grid blackouts causes and consequences, their comparison to each other and to the Dukovany nuclear power plant grid blackout drill scenario. The preventive and standard corrective measures against blackouts are pointed out.

Critical Parameters for Wireless Networks WiFi and WiMAX
Grenar, Milan ; Křepelka, Václav (referee) ; Baroňák, Ivan (referee) ; Filka, Miloslav (advisor)
My thesis will be aimed at problems of wireless networks WiFi and WiMAX. A modelling of network will be put into effect onto which the measurement will be implemented and the impacts of network load on the data transfer Quality of Service (QoS) will be examined with aiming at VoIP. On this network model a power failure will be simulated and the impacts of this failure after restoring the power supply will be monitored. The aim of this thesis is to check the rate of network throughput while preserving a providing service quality and to suggest an economica1ly acceptable solution of the problems relating to feeding tension outage of the access point (AP) for a practical usage in these networks.

Design and Realization of a System for Masking Dispatcher PC Cut-Off by Backing-Up Data Obtained from TAMRON Weighing-Machine
Štulír, Vojtěch ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
In the productive operation any kind of plant is undesirable due to failure of system that all production has been stopped. Therefore, different security and backup devices that covered those failures are being developed and used. This thesis describes vulnerabilities in the real operation which are important for treatment and reduce the risk of failure in the whole production. Here is analyzed problem dispatching computer failure and its solution using a module for covering failure. The function of module consists in backup during failure, their sending and treating them after system failure removal. Gradually described, there is an analysis of the system and place the module into their architecture. After all details follow description of module development from design through implementation to deployment and testing in reality.

Early Warning System for recording outages from the assembly line
Makovičková, Lucie ; Zuth, Daniel (referee) ; Maradová, Karla (advisor)
The bachelor's thesis on a topic “Early Warning System for recording outages from the assembly line“ aims to update assembly line outages, thanks to what the work gained a good motive to present the Early Warning System process in practice, in the company Bosch Diesel s.r.o. Jihlava, where this update of assembly line outages takes place. The work first introduces the high-pressure pumps and their assembly lines, which are the most connected to the system. Then the basic elements of the system are described, and the Power BI system is defined. The practical part explains way of collecting the necessary data for outages updating and how the Early Warning System gets the information about outage during the installation of a high-pressure pump on the assembly line to the higher responsible persons. Subsequently, thanks to the obtained statistical overview of all outages and to the performed visualizations in the Power BI system, the knowledge is evaluated.

An analysis of safety measures Tipsport arena for dealing with emergencies
Benko, Michal ; Fiala, Miloš (advisor) ; Vilášek, Josef (referee)
Title: An analysis of safety measures in Tipsport arena for dealing with emergencies Objectives: The aim of this thesis is to describe and analyze technology in Tipsport Arena ice stadium in Holešovice in terms of safety and security measures and to evaluate the internal measures of HC Sparta Praha. Identify emergency situations that may arise at the ice rink and bring preventive measures generated against these situations. Methods: In this thesis compilation methods were used for the analysis of the key points about technology and hazardous substances used at the ice rink, security plans arising from legislation and an analysis of the integrated rescue system. In the practical part, a technology and safety measures selected ice rink, the used of methods of analysis, observation and interviews. Results: Safety measures Tipsport arena is evaluated as positive and its analysis is given in the safety measures servicing of refrigeration devices, security controls before organizing events, breakdown of activities performed by fire hazard and are accompanied by the documentation of fire protection in Tipsport arena. Keywords: leak, ammonia, system, stadium, failure
