Design of technical measures in LV distribution network with a high value of short-circuit currents
Šmehlík, Daniel ; Bátora, Branislav (referee) ; Ptáček, Michal (advisor)
This bachelor thesis discusses the sizing and the possibility of reducing large short circuit ratios. For a specific scheme of an industrial building, which will be fed from three transformers, the sizing will be done by means of the SICHR program. The specific objective of the technical solution is to be able to use modular circuit breakers with a ripping capability of short-circuit currents up to 10 kA in the terminal switchboards. Another objective of the work is to perform an economic evaluation of the proposed solution, or to optimize the design from the point of view of the economic aspect in meeting the technical requirements.

Design of a manual milling head designed for technological operations on medium heavy workpieces
Nedbal, David ; Pavlík, Jan (referee) ; Holub, Michal (advisor)
This thesis deals with mechanical design of right-angle manual milling head for headstock of horizontal boring machine of Fermat production. The thesis includes research of milling head types, Fermat production heads, but also heads of competition companies with similar parameters like designed head. Design part of thesis is about describing used components of chosen solution. The thesis includes also technical report describing calculation of load spectrum from machining, design of gears, calculation of reactions in spindle bearings, spindle deformation and control of spindle bearings. The end of the thesis describes financial evaluation including also comparation with competitive milling heads with similar parameters.

Regulating weeds in the cover of oilseed (Brassica spp.).
HASÍK, Juraj
The thesis contains various methods of regulating dangerous weeds occurring on arable land in the cover of oilseed. It also contains a brief description of how the actual oilseed (Brassica spp.), as well as various weeds that are widespread in oilseed covers. The actual work took place at the at the School Farm the Agricultural Technical School in Tábor. A small-plot experiment was conducted here. The evaluation of the frequency of weed occurrence n the selected experimental plots was conducted in two varieties of oilseed and two hybrid varieties of oilseed. The findings of different varieties were compared. At the conclusion of the actual work, the thesis includes economic evaluation and the proposed measures.

Technological lines for maintenance of permanent grass vegetation in the protected landscape areas.
NAHODIL, Antonín
The thesis deals with technological lines for the maintenance of the permanent grass vegetation in the protected landscape areas. The theoretical part describes what are the protected landscape areas and National Parks. Moreover the agro-technical requirements and terms for the performance of individual operations while harvesting the fodder are included there. Also the characteristic signs of individual sites are involved: altitude, slope, natural obstacles, dimensions of the plot and its orientation. The practical part involves the assembly of technological lines for harvesting the hay and silage with high contents of dry matter. Technical and technological requirements on individual mechanization means and operation. Economic evaluation of suggested procedures.
