4G mobile network design issues
Žůrek, Martin ; Škorpil, Vladislav (referee) ; Novotný, Vít (advisor)
he first section briefly describes the history and development of mobile telecommunications networks, by their standards and the gradual development of global initiatives for the unification of the network. The second part of my work is focused on the latest generation cellular networks. The transition from the previous generation of networks and communication between them. Including differences in the architecture of the fourth generation. Description of the basic blocks of a new core and access networks, its use for commercial purposes.

Reliability and Communikation in Man-Machine-Systems
Kovář, Tomáš ; Žurek, Martin (referee) ; Havlíková, Marie (advisor)
The objective of this work is to analyse the technical and human reliability in the man-vehicle system. The reliability of the whole system is given by the individual reliabilities of technical subsystems and human operators. In the analysis of safety and readiness of technical systems, it is necessary to monitor human effects on the reliability, safety and readiness of these systems, which directly put people’s lives at risk. The human operator influences the safety and reliability of the whole system by his actions and operation of the device. The quantitative evaluation of human reliability is based on an overall probabilistic safety analysis. Since drivers directly control the means of transport, the human operator’s reliability is entirely determining for the overall reliability of the system. External and human factors influencing performance affect the man-machine system. The activity tree model serves for the evaluation of reliability of the MMS system and provides a concise, organised and well-arranged description of defects within the system.

Model of the lift including AS-Interface network
Žůrek, Martin ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
This bachelor´s thesis occupies with a suggestion of the model of a lift which is driven by a serial industrial bus AS-Interface. In the introduction there is presented theoretical knowledge useful for the reader to the problems especially of the origin and fundamental parametrs of bus AS-Interface, description three levels referential model ISO/OSI which are included in AS-Interface. Further there is the description of transmission of analogical values and standard profiles which are used. In the other part I am trying to solve the model of the lift from the construction standpoint and function of component parts which are included in the lift model. The fourth part devotes to the communications protocol for the control of storeys and the cab box which are shown the data transmission between unit master and unit slave and the opposite. In the last part it is shown programming environment and routines and functions and connection unit slave to unit master. Enclosed are electrotechnical schemes of the model of the lift, the block of programme structure for PLC and technical docummentation of components.

Control of lift model
Žůrek, Martin ; Bradáč, Zdeněk (referee) ; Štohl, Radek (advisor)
My graduation theses is focused on project of algorithm proceedings laboratorial model of a lift and visualization in computer program Factory Talk View Studio. In introduction is written about industrial comunication network AS-Interface and in practise used algorithm proceedings of a lift. In following capitol is described system and several parts of laboratorial model of a lift. Not least is solved also comunication among floors of a lift, cabin and master AS-Interface and project of functional block in computer program RSLogix 5000. General purpose of master’s theses is project algorithm proceedings of a lift which use double-sided collecting proceedings. In last chapter is noticed project of visualization, which control a lift.
