Assesment of the meaning of Polarization Mode Dispersion
Červenka, Vladimír ; Rampl, Ivan (referee) ; Kyselák, Martin (advisor)
This thesis describes the most important types of distortions in fibre optics during transmission. They are divided into two main groups, linear and nonlinear. The linear phenomena consist of internal and external attenuation, different kinds of dispersions and negative effect of signal noise. The special attention is focused on polarization mode dispersion. The impact of the nonlinear phenomena on fibre optics in high date rate is discussed as well. Furthermore, the negative effects in fibre optics and their causes are deeply analyzed on results gathered from simulation of some transmission lines. There are presented many methods for counting the meaning of polarization mode dispersion, for example the theoretical model including implementation on physical layer and reducing power looses. Some examples of designing fibre optic lines are introduced along with calculation for them.

Measurement automation of simple electrical circuit
Gála, Michal ; Čala, Martin (referee) ; Havlíková, Marie (advisor)
Document describe simple electrical circuit from theory and subsequently complex double-port from practical measure. On measurement is using automated measuring system. Document describes the adjustable parameters of measuring devices used in automated measuring system, the reason why they were chosen and the practical implementation of the measurement system. Process control measurement is used on measurement application. Document concerns the choice of program, which is use of programmed measuring application, and also analyze various subtasks in specifically stages of application. Document presented the functionality of measuring applications with a consistent example of measurement. In conclusion of document is contain evaluation of the results that have been achieved during development.

Usage of Modern Methods for Increasing Reliability of Control System Implementations
Szurman, Karel ; Mičulka, Lukáš (referee) ; Kaštil, Jan (advisor)
At avionics control and critical systems is necessary guarantee a minimal level of fault tolerance and their high reliability. On the electronic components in these devices has an undesirable influence environment conditions and mainly cosmic ray. In this paper are described the most common failure types of semiconductor components and devices together with modern methods which can be increased the system fault tolerance and its overall reliability. There are introduced aspects of the avionic systems design due to finally certification and ways to evaluate its safety. This thesis describes design and implementation of the CAN bus control system for the FPGA platform which uses the CANAerospace application protocol. Created system design is improved by the TMR architecture. Fault tolerance of both system version is tested by the SEU framework which allows using the dynamic partial reconfiguration generate an SEU failures into running FPGA design.

Návrh dílčí části systému pro monitoring bezpečnostních incidentů
Koch, Michael ; Neuwirth, Bernard (referee) ; Novák, Lukáš (advisor)
The thesis focuses on the implementation of a part of the information system for security incident analysis within PwC. The system serves to complement the current solution, which lags behind future and existing requirements. The first part describes the theoretical background to understand the concept of the thesis and the technologies used in the implementation of the system. The following section contains an analysis of the current state of the existing system. The principle on which it works and the shortcomings that caused the necessity to implement a new solution. The third chapter deals with the actual design and implementation of the new solution. In the last part of the thesis an economic evaluation of the costs and benefits of the solution is made.

The quality evaluation system of the low-threshold club Jahoda services
Weiderová, Jana ; Pazlarová, Hana (advisor) ; Matoušek, Oldřich (referee)
Diploma thesis "The quality evaluation system of the low-threshold club Jahoda services" deals with questions of evaluation and rising of social services quality, which is the primary objective for well functional organization in commercial as well as noncommercial zone. Thesis is primary applied to sphere of social services and its aim is making proposal for evaluation of services quality for concrete institution providing low-threshold social services to children from 6 to 15years old. The first part describes social services in legal social services in legal and describes low- threshold institutions for children and teenagers, representation low-threshold club Jahoda. Next targets are about possible styles of evaluation provided services quality and their fixation in standards of social services quality. The second part of thesis is practical part, which attends to the proposal of system for quality evaluation offered services in low-threshold club Jahoda. Proposal of this system is coming out from analysis of present system used in the institution and its main part is questionnaire investigation between users, employees, volunteers and trainees of NZDM Jahoda. Pilot was tested between all persons interested in and its representation is a part of the thesis to.
