Digital twin skin of the drinking water treatment plant - development and use in practice
Sochorová, Helena ; Andreides, D. ; Hložanka, F. ; Prokopová, Michaela ; Stejskal, O. ; Chalupa, L. ; Šmejkalová, P. ; Dolejš, P.
The contribution presents experiences with the development of a digital twin for optimizing the control of the DWTP within the pilot project in the Železná Ruda locality. The digital twin consists of two components, i.e. digital documentation in the object architecture processed by the reverse engineering process, which is data-connected with the real physical infrastructure (virtual replica of the infrastructure) and a simulation tool based on a mathematical model or a neural network (simulation of the water treatment process). Both components are accessible to the user via a web application, in which one can choose from three operating states (monitoring of the real state - default, simulation of scenarios of operating settings and prediction of pressure loss).

Stellite cladding on steel 1.4122
Daumer, Tomáš ; Stejskal, Ondrej (referee) ; Kubíček, Jaroslav (advisor)
Master‘s thesis describes issues of stainless steel welding. The analysis carries out the stainless steel‘s state of art in term of welding, chemical composition, physical and mechanical properties. Experimet is based on cladding of Stellite alloys to martensitic stainless steel X39CrMo17-1. The practical part describes the used devices and carries out evaluation of specifically designed heat input, macrostructure and hardness.

Kryomacerace v technologii bílých vín
Stejskal, Ondřej
The thesis deals with kryotechnology and wine production using kryotechnology and monitoring molar substances of wines produced by kryotechnology in comparison to classical production. The first part introduces the maceration of grapes for white wines and methods of maceration, then the factors that influence the maceration, the next section deals with the fabric composition of berries and eventually meet with kryotechnology and its methods. In the experimental part is a brief description of all the three varieties of which the experiment was performed. This is followed by a description of the conduct and methods of production well and finally this section is being set of analytical and sensory methods to be performed. In the results, we will learn what conclusions and opinions we have come here and see clearly expressed the results in graphs where it is clearly shown how the wine itself developed from primary production.
