Design and realisation of microwave directional coupler
Nejedlý, Miroslav ; Motl, Milan (referee) ; Dvořák, Radek (advisor)
The diploma thesis deals with microwave directional coupler. The paper presents some of the microwave directional coupler and an analysis of bifurcations. The paper also discussed the various techniques of bifurcations and the bandwidth to which they are making. Proposal is implemented in two selected directional couplers and determining their size. They also performed using the selected simulation program selected two bifurcations. Furthermore, these couplers are made on the perimeter of the analyzer is verified by their actions and are verified by the actual parameters of the coupler.

Power impulse current sources
Nejedlý, Miroslav ; Fiala, Pavel (referee) ; Drexler, Petr (advisor)
This project deals with the probleme of the power pulsed current source. In this work, there is a study of some generators of pulsed current and than there has been made a design of power pulsed current generator. For the switching purposes the power switch based on the thyristor module has been designet. The advantages and disadvantages are discussen. The designed current source has been experimentally realized. The measurement of its parameters was performed.

Components of the environmental monitoring and its evaluation on the locality of MAPE Mydlovary.
NEJEDLÝ, Miroslav
On the locality of MAPE Mydlovary, where was fuctioning chemical concentrator of uranium ore, were made sludge beds. The sludge beds are significant landscape component, that dramatically take effects on the environment. That is why is important to pursue the monitoring to get the datas for detecting the influences of sludge beds on the environment. The aim of this dissertation is to evaluate the components of the environmental monitoring and state the results of recultivation on the locality of MAPE Mydlovary.
