Unstability cut of laser beam at dividing limiting gauge thickness
Kadlec, Zdeněk ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This thesis deals with the possibilities of cutting strong steel metal sheets by means of laser and problems rising from the incision, their technological investigation. The basic philosophy consists on the research of the interaction between laser bunch and material, depending on the position of focal poin and sequential results in spec. heat. It determines the main parametres of the incision (from the total quantities and matematical description) which have the biggest effect on the occurence of wide cut and perhaps even on the quality of products and consequential optimalization of these quantities.

Consequences of deliberate chlorine leakage from Spolchemie plc, Usti nad Labem, and Spolana plc, Neratovice
KADLEC, Zdeněk
Most of the current population cannot imagine their contemporary lifestyle without chemical products. This requires the chemical industry, which in some areas of our country is well developed. Spolana and Spolchemie are large chemical companies, which store huge amounts of chlorine. The aim of this study was to evaluate the simulation of leakage of chlorine from Spolana and Spolchemie using TerEx software and see if the two businesses can be important sources of risk for the population in terms of leakage of chlorine. Results of this study imply much larger consequences that would be caused by potential leakage of chlorine through intentional misuse. This possibility should be of interest to not only integrated emergency services and members of crisis management teams, but also the citizens themselves. Preparing for such an event and knowledge of things in terms of prevention is very important.
