Model of small air press
Uherek, Vítězslav ; Macho, Tomáš (referee) ; Štohl, Radek (advisor)
This thesis deals with design construction of laboratory model of air press and also proposes of safety measures for this machine. Before the design itself, norms concerning machinery construction were surveyed. There are two norms mentioned in the text ČSN EN 61 508 and ČSN EN ISO 13489-1. Next part shows practical demonstration of machine safety analysis using SISTEMA software tool. Changes to the safety measures were made according to the result of this analysis. Important part of this thesis is also design of control software for the air press in RSlogix5000 environment using Ladder logic and also created visualization of pressing process and show up on to visualization panel PanelView 700.

Fuzzy logic methods for the risk assessment
Kovář, Kamil ; Vymazal, Tomáš (referee) ; Misák, Petr (advisor)
Master´s thesis deals about problematic of fuzzy logic, fuzzy sets and operation with them. Also thesis describing procedure of quantification risks through fuzzy sets, process of fuzzyfication, defuzzyfication a theirs application in the expert systems FMEA and FMECA. Using selected chapters of czech states standards are established critical areas in building process, it is a chapters about quality, safety and environment. With these areas by using fuzzy sets theory are created the procentual input values in the decision program, created by Matlab. Output from program is decision how big the risk rate is and if is necessarily make corrective measures. A concrete example is the production of concrete goods, describing production process and composition of fresh concrete. A practical example, created by using information from real company, is a decision about the risk rate in the qualitative area.

Security Risks in Passive Optical Networks
Šimoník, Jan ; Jeřábek, Jan (referee) ; Horváth, Tomáš (advisor)
This diploma thesis deals with the historical development of passive optical networks, according to the standards that was defined by International Telecommunication Union (APON, BPON, GPON, XG-PON and NG-PON). Further, the thesis describes the security of passive optical networks, but also a security threats which the deployment and use of passive optical technology carry. In the introductory chapters of this thesis the passive optical networks are described. The following is a description of the standards of passive optical networks in terms of their historical development. The next part is dedicated to the security of passive optical networks and possible security threats. In conclusion a description of the practical part of this thesis is given -- rack assembly, which will serve for future testing. The basic configuration of the optical line terminations that are fitted in the rack is also described. The last part of this diploma thesis is dedicated to the testing of selected security risks, which was described in the theoretical part of this thesis.

Production control system to solve safety risks
Jelínek, Vojtěch ; Zezulka, František (referee) ; Pásek, Jan (advisor)
This bachelor´s thesis deals with a description of automated manufacturing process with solution of safety risks in the industrial company SWOBODA.CZ. In the first part are placed an information about operating procedure of manufacturing process, conceptions of the control and safety and information about the specific hardware and software. Next part contains program which deals with safety of machine and description of visualization and control of machine. In the end is described program for testing error statuses of machine and their announcements.

The evaluation methodology operating status of cranes
Sedláčková, Martina ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The main theme of this bachelor's thesis is to design a procedure for the evaluation of the operating status of warehouse and workshop cranes. This methodology was tested in practice. This document also contains an overwiew of the main security risks arising form the poor condition of cranes, as well as an overwiew of places where defects on crane occur most frequently. The annex also contains photographs form the practical part.

Analysis of information leakage from optical transmission system
Šimon, Václav ; Horváth, Tomáš (referee) ; Münster, Petr (advisor)
This bachelor thesis deals with the structure of an optical transmission system. It focuses mainly on the transmission part of the system. It describes its parts and the functioning of the components used. It also deals with the risks of information leakage at various levels of the system (backbone networks, distribution and access networks, optical fiber). The practical part examines the issue of 3 possible risks. Firstly is measured the effect of unauthorized connection of a splitter to the optical path, then the eavesdropping in dense wavelength division multiplexing networks and the last measurement deals with the eavesdropping of the upstream signal in GPON access networks.

Preparation for rough superstructure accommodation pavilion in Brno
Šenk, Marek ; Kučera, Zdeněk (referee) ; Kantová, Radka (advisor)
The bachelor thesis deals with the construction technological solution of the rough top structure of the accommodation pavilion in Brno on Veslařská street. For the given technological phase a time schedule for construction, an itemized budget with a statement of dimensions, a technical report and drawings of the construction site equipment, a technological regulation, assessment of transport routes, design of the main machines and mechanisms, a control and test plan, security risks and their prevention are elaborated. The last chapter deals with the comparison of 3 possible options in terms of financial, time and thermal technical assessment.

Increasing the safety of the outside perimeter
Janoušek, Jiří ; Fiala, Pavel (referee) ; Marcoň, Petr (advisor)
This thesis deals with increasing the safety of the external perimeter. The theoretical part describes the parameters of areas exhibiting an increased safety risk. For these spaces, relevant safety hazards and corresponding elimination methods are determined. Then, the term "drone" is analyzed in the context of its applicability. The practical section characterizes the process of building and configuring unmanned aircraft to guard the perimeter and the designing and fabrication of an automatic charging station for the aircraft. The final part of the thesis is a brief manual describing correct handling of the created system.
