Presence of heavy metals near the way Rudná
Chovanec, Petr ; Pavlovský, Jiří (referee) ; Doležalová Weissmannová, Helena (advisor)
These diploma thesis is focused on assessment of hazardous metals in soils near the road Rudná in Ostrava. Seventeen sampling sites have been chosen along this road, samples from this sites were collected in three series. The amounts of mercury, lead, copper, cadmium, zinc, vanadium and manganese were determined. There was also assessed contamination of selected sites using contamination factor and degree of contamination.

Hranice výrobních možností a stochastické programování
Chovanec, Petr
By its nature, Data Envelopment Analysis (DEA) leaves no room for uncertainy in data such as measurement errors. To improve this fact, we consider $alpha$-stochastic efficiency concept, and we relate this problem to the stochastic programming problem. Two types of probability inequalities are employed for introducting new criteria for efficiency.

Nová kriteria pro stochastiku DEA
Chovanec, Petr
By its nature, Data Envelopment Analysis (DEA) leaves no room for uncertainty in data such as measurement errors. To improve this fact, we consider a-stochastic efficiency concept, and we relate this problem to the stochastic programming problem. Probability inequalities are employed for introducing ew criteria, and two special cases for normal and for general distribution are discussed. The strengths of new criteria are illustrated with a numerical example.
