Proposal of process control in production safety valve
Jaša, Aleš ; Prokop, Jaroslav (referee) ; Pernikář, Jiří (advisor)
The aim of this thesis is precise definition of control processes for components of Pressure Limit Valve 5 Generation (PLV5) which is produced by Bosch Diesel Ltd. in Jihlava. The objective was to define measurement methods which ensure identical results of measurement between co. Bosch Diesel Ltd. in Jihlava and suppliers of individual components. The results of this study are introduced into control drawings and described in individual conclusions of the thesis.

IMS multimedia services
Dohnálek, Václav ; Martinásek, Zdeněk (referee) ; Mácha, Tomáš (advisor)
This master thesis refers to a new technology in a mobil services IP multimedia subsystem. First, the theoreticl part, refers to the architectury of this technology and elementary protocols. Although it is real-time services, is nesessary to refer about the Quality of Services, that it ensures the condent transmition of data. The second, practisy part refers to a the development background SDS 4.0 FD1 from Ericsson ltd., that it is used develop aplications for IMS technology. It will be to develop the aplication , that it used to the IMS and it refers to the elementary function and comunication.

Ovality measurement of extruded fiber using three cameras
Loučka, Pavel ; Martišek, Dalibor (referee) ; Štarha, Pavel (advisor)
One of the important parameters observed during extruded fibre fabrication is its diameter. The diameter can be measured with a single scanning camera assuming that the fibre section has a circular shape. As proved in practice, another important parameter is ovality, that is the rate of fibre flattening. This paper assumes that the fibre section shape is elliptical. In such a case, at least three different views on examined fibre are needed. Mathematical part of this paper is concerned with analytical description of fibre ovality measurement using two different approaches based on the knowledge of linear algebra, projective geometry and conic sections theory. Main goal of this paper is thus to use both mathematical theory and image analysis methods for ovality and diameter determination. Precise calcluation of such quantities is, however, conditioned on precise camera system calibration, which is described in the paper as well. Additionally, the work contains a brief mention of technical realization of ovality measurement and its possible difficulties.

Rotary part produced on CNC machine
Ratica, Filip ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
The diploma thesis contains an overview of the development of numerical control of machine tools and a historical excursion of the beginnings of numerical control. The work deals with the design and presentation of the component, and then the calculation documentation used to determine the load and safety of the component. After computational and design analysis, the work deals with the design of component production on CNC machines and the technological process of production. Finally, the production of the part is documented and evaluated.

Design and implementation of an IMS network with extended functions using Open IMS Core.
Šulgan, Peter ; Šilhavý, Pavel (referee) ; Ježek, Jiří (advisor)
The bachelor thesis focuses on the architecture of the IP Multimedia Subsystem, its main elements and extension functions. It also deals with the implementation of the IMS network in the simulation environment Open IMS Core, which is also briefly described. The first chapter describes the IMS architecture divided into layers and it also defines the basic elements such as CSCF and HSS. In addition, it briefly characterizes the most commonly used communication protocols and the structure of identity in IMS. The second chapter deals with the open source environment Open IMS Core, it briefly defines the individual parts and contains a list of configuration files. The third chapter introduces the additional services offered by the IMS architecture. It characterizes their basic functions and their way of working. The fourth chapter focuses on the practical part of the bachelor thesis. It describes configuration procedure of the Open IMS Core and testing of its functionality. It is divided into four sections according to the individual configuration steps.

Design of outlet and intake objects of Nové Heřminovy dam
Neuvirt, Petr ; Švancara, Jiří (referee) ; Zachoval, Zbyněk (advisor)
In this thesis was presented Nové Heřminovy dam with basic parameters. Requirements on bottom outlets and intake objects are presented as well. Analysis of used valves on all dams in Czech Republic was done as an underlay for suggestions of bottom outlets in this thesis. The main task was to suggest three variations of bottom outlets. Differences are in number of outlets, dimensions, placing and valves. Then variation of intake objects. Each of variation was verbally described and filled with calculations.

Evaluation of Nuclear Fuel Safety and Reliability Using Research Reactors' In-Core Experiments
Matocha, Vítězslav ; Foral, Štěpán (referee) ; Katovský, Karel (advisor)
The aim of this master thesis is to show a connection among nuclear fuel safety, experiments led in research reactors and calculation codes. This thesis focuses on the calculation code Transuranus. There are represented four experiments, which were calculated in Transuranus. The fission gas release, elongation and growth of fuel were particularly monitored. Is is possible to set differences among versions v1m1j09 and v1m3j12 from achieved results, as well as the influence of selected Transuranus parameters on the results, so the thesis may bring new pieces of knowledge for improvement of safety analysis calculation by Transuranus.

Surveillance system for Internet Protocol Multimedia Subsystem
Švec, Michal ; Doležel, Radek (referee) ; Nagy, Ľuboš (advisor)
The master’s thesis describes IMS (IP Multimedia Subsystem) in terms of IMS core ele- ments (functional description, different implementation, signaling etc.) Communication protocols SIP and DIAMETER, together with SNMP protocol, which is used for collecting data are briefly described in this thesis.Thesis is also describing various IMS projects to- gether with Open IMS project, for whom was this surveillance system designed. Next part deals with architecture design of surveillance system along with management options implemented in surveillance system for users and administrators. The main part of master’s thesis deals with the description of the surveillance system for the experimental school Open IMS network and describes the remote configuration of core elements and monitoring of network traffic, together with the monitoring servers performance. The most of the data in the designed surveillance system are processed into graphs, which are regularly updated. The final part of master’s thesis describes the configuration and implementation of monitoring tools MRTG and NfSen that were used in created web based surveillance system.

Porovnanie AAA protokolov pomocou Petriho sietí
Baloga, Ľubomír
The diploma thesis deals with AAA protocols. The first practical part of thesis was deployment of protocols independently on virtualized computer networks and test their functionality. Next practical part of thesis is about models created with colored Petri nets. The aim of the thesis was to test the individual protocols using Petri nets as well as on the created computer networks. The result of this work is a summary of the possibilities of using protocols in practice because these protocols are rela-tively outdated but often used today.
