Concept of linear motors measurement workplace
Knobloch, Jan ; Červinka, Dalibor (referee) ; Klíma, Bohumil (advisor)
Master’s thesis handles about measurement on linear motors. Acts about set of two linear machines on one rail. One is motor and second is load. Thesis paies their mathematical description, control and measurement. It’s made measurement of the linear motor load characteristic. Next measurement have to do with losses in the converter. Is chosen measuring instrument t for measurement during working cycle. During working cycle has determine power eciency of entire drive.

Mechanical and chemical control of Canada Thistle
KORDOVSKÝ, Ondřej
Canada thistle is perennial deep-rooting weed.On the arable land there caused some problems:compete to cultivated crops, make more difficult harvest and lowers quality of products. Possibilities of control were evaluated at V farm Křepiny with respact to possibilities of chemical control. In cereal field were used selective and non-selektive herbicides during the vegetation period, before harvest and ofter harvest. Ofter herbicide control were evaluated decrease of Canada thistle plants.
