The agrarian share sugar refinery Němčice nad Hanou (1910-1948)
Lecián, Petr ; Jakubec, Ivan (advisor) ; Hájek, Jan (referee)
The purpose of my paper was to outline the time of appearance and development of the sugar refinery industry in both central and northern Moravia and Silesia on the basis of the historical and current literature and utilisation of the archive funds of MZA in Bmo. The thesis covers a time period from the first half of 19th century till the year 1948 when the sugar refineries were nationalised. I have divided my paper into several chapters following the establishment of single sugar refineries in Moravia and Silesia. The first half of the paper is focused on the attempts of sugar production from the maple juice or the sugar beat. The sugar production expansion started by the foundation ofthe first sugar refinery in Kostelni Vydfi in the year 1829 and by the continuous sugar production development starting with the aristocratic establishments, the enterprises owned by the wealthy entrepreneurs and following up with the small fanner's stock sugar refineries, whose stockholders were the Czech fanners. The second part of this paper is dedicated to one of the most significant and most modem small farmer's sugar factories in Moravia, which was located in Nemcice nad Hanou. It was the first small fanner's sugar factory with its own refinery for the white sugar production. There is also one chapter clarifying the...

Analog-Digital Converter Unit with Data Output by Serial Line
Lecián, Petr ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
This work is about measuring voltage and manipulating with this way obtained data. Manipulating system is in this case 16-bit microcontroler PIC by Microchip, that transforms input data to output using known non-linear trace. Microcontroler has been programed in the symbolic adress language. I had to create a unit that would be a part of the special device for indirect measuring non-electric quantity. Output data should be sent to the superior system by serial bus RS-232 for a next use.

Parabolic antenna feed for X band
Lecián, Petr ; Mazánek,, Miloš (referee) ; Kasal, Miroslav (advisor)
The work addresses the unusual proposal feed for parabolic antenna with circular polariza-tion signal. This is a modified waveguide feed, waveguide polarizer with a septum. Contemporary RHCP and LHCP wave occurs in several applications of microwave commu-nication and measurement system. From this point of view the septum polarizer can be useful. The septum polarizer is a four-port waveguide device. The square waveguide at one end con-stitutes two ports because it can support two orthogonal modes. A stepped septum divides the square waveguide into two standard rectangular waveguides sharing a common broad-wall. The size of the septum as well as two versions of the waveguides excitation were analyzed and are described in this paper. Ansoft HFSS is software for design and simulation of feed. This software can visualize not only the specified model feed, but also the course of electromagnetic field in feed and over time.
