Electrically short multiband antenna for radioamateur use
Müller, Marek ; Šebesta, Jan (referee) ; Lukeš, Zbyněk (advisor)
The purpose of this work is identification with theory of EH antennas, do the simulation of one choice of model of EH antenna from literature and this model optimise on required frequency 14 MHz through the use of computer software CST Microwave Studio. The practical part of work is to produce choice model of EH antenna, to mete his properties and to verify use in real traffic. The EH antenna is an electromagnetic electrically short antenna, which can work as a transmitting or receiving antenna. The main characteristic of EH antenna is distributed radiating electromagnetic field, whose electric component E and magnetic component H are mutually crossed and orthogonal. The advantage of EH antennas is, that they have much smaller size on frequencies in order of magnitude MHz in comparison with conventional antennas (e.g. half-wave dipole). Their disavantages are their more complicated construction and tuning of the antenna, which must be made again, when the position of antenna is changed. Therefore the EH antenna is not so suitable for mobile application.

Adaptor for the Group Delay Measuring
Müller, Marek ; Kratochvíl, Tomáš (referee) ; Říčný, Václav (advisor)
The purpose of this work is to propose the adaptor for the group delay measuring. This equipment would be worked as one special device, which it connects between wobble generator (for example wobbler X1-50) and measured circuit. This configuration can be measured not only the dependence of group delay on frequency at the measured circuit, but it can be measured even its amplitude - frequency characteristics. Whatever oscilloscope can be used for displaying of measured characteristics in the event of the application of other separate wobble generator, when the oscilloscope works in XY mode. The utilization of the equipment can be for example for the group delay measuring of intermediate frequency amplifiers by TV sets at frequency band since 30 MHz to 50 MHz. This equipment is able to measure the group delay time within the range since 0.56 ns to 2 s.

Social security of people with disabilities
Müller, Marek ; Vysokajová, Margerita (advisor) ; Štangová, Věra (referee)
Social security of people with disabilities The thesis deals with social security of people with disabilities. Its aim is to analyse the legislation valid for the Czech republic and its implementation in real life situations. The thesis consists of six chapters. The first chapter aims to clarify basic terminology necessary to fully understand issues of social security of people with disabilities that will be used throughout the thesis. The second chapter is devoted to legal sources, that deal with social security of people with disabilities focused on provisions of international law, national and European Union law. The third chapter describes social security of people with disabilities within the realms of "Pension Insurance Act". It discusses various levels of disability pensions and the proces of health assesment in detail. Issues of management and further organization of pension insurance. The fourth chapter focuses on non-insurance social benefits for people with disabilities. It further describes the management and organization of these benefits. The fifth chapter deals with care allowance for the disabled intended to cover costs of necessary social services. It also describes the proces of legal proceedings for granting the allowance and its organization. Chapter six describes the...

Social security persons
MÜLLER, Marek
The purpose of my batchellor thesis is to bring some informations about system social security of persons with visual handicap. The author of this thesis finds the topic attractive and interesting. Also, the topic has been chosen because of its closeness to the author, who has been suffering from total blindness since birth. The bachelor thesis pursues the analysis of social benefits, which are oriented to people with visual handicap.
