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).

Characterization of regenerated humic acids
Ivancová, Anna ; Ing. Daniela Šmejkalová,Ph.D. (referee) ; Kučerík, Jiří (advisor)
The work deals with the physical characterization of humic substances, namely potassium and ammonium salts of regenerated humic acids extracted from South-Moravian lignite. The regeneration of lignite was based on the oxidation of lignite by means of nitric acid and hydrogen peroxide. Obtained samples of humic acids were analyzed by elemental analysis, which confirmed that the regeneration changed the distribution of elements in respective humic acids. Diluted aqueous solutions of humates were further analyzed by densitometer and high resolution ultrasonic spectroscopy. Obtained data were used for the determination of the compressibility and hydration. The relationship between those two parameters and way of humic acids preparation was discussed.

Advantage and disavantage of the development of pre-mathematics literacy in "wood kindergarten"
Šmejkalová, Petra ; Kaslová, Michaela (advisor) ; Havlíčková, Radka (referee)
This Diploma Thesis deals with possibilities of developing pre-mathematical literacy at Wood Kindergarten. The Thesis submits a proposal of Kindergarten Education Programme concerning this aspect. The proposal is the result of a detailed theoretical part which precedes. The concept of this Educational Programme aimed at pre-mathematical literacy in a specific environment focuses primarily on the development of manipulative motor skills connected with special orientation and the child's individual body scheme. The practical part verifies suitability of selected activities related to the specific environment of forest and other kindergarten surrounding environment. This Thesis is based on 'action research' combined with qualitative research elements. It introduces a new perspective regarding the issue of preparing children for school mathematics.

Comparisons of softball swing at pitches from a pitching machine and pitcher
Šmejkalová, Petra ; Carboch, Jan (advisor) ; Pravečková, Petra (referee)
Title: Comparisons of softball swing at pitches from a pitching machine and pitcher Objectives: The aim of this research is to compare the timing of players of softball within individually phases of hitting by a standard softball pitcher and a pitching machine. Another aim is to analyse individual phases of softball hitting and determine whether the training of hitting through a pitching machine is a appropriate substitute for the preparation of a standardized softball pitching which softball players experience during each match. Methods: This research is a descriptive case study, in which we gather a large number of data from five individuals. A ride of five players and their execution of hitting approaches against a pitching machine and real pitcher was created. Subsequently the record from the camera Basler GeniCam piA640-210gc with frame rate 200 frames per second was then evaluated via of computer program Dartfish, which is designed for analyses of motor skills. Results: The results show that the whole movement of players was noticeably slower, in the case of a pitching machine use. Regarding the use of a pitching machine and real pitcher, the statistic results show differences. The differences derive from the absence of conscious prediction of pitches motion in the case of the pitching...

Evolution of Retortamonadida (Eukaryota: Excavata: Fornicata)
Smejkalová, Pavla ; Kostka, Martin (referee) ; Čepička, Ivan (advisor)
Retortamonads (Retortamonadida; genera Chilomastix and Retortamonas) are a small group of protists comprising intestinal commensals of both vertebrates and invertebrates and one free-living species of the genus Chilomastix. Molecular phylogenetic studies showed that retortamonads are closely related to diplomonads, Carpediemonas, Dysnectes, Hicanonectes, Kipferlia and two undescribed lineages of free-living Carpediemonas-like organisms, together forming the monophyletic excavate group Fornicata. For a long time Retortamonadida have been assumed to be a monophyletic group. However, first molecular phylogenetic study including sequence data from both Retortamonas and Chilomastix suggested that Retortamonadida are paraphyletic and that diplomonads branch within Retortamonadida. Retortamonads still remain poorly studied protist group and their phylogeny is unclear. We sequenced and analysed SSU rDNA of ten Retortamonas and four Chilomastix SSU rDNA sequences. In addition, we sequenced SSU rDNA of an undescribed enteromonad lineage. The phylogenetic tree of Fornicata was largely unresolved and the phylogenetic position of the genus Chilomastix remained unclear. On the other hand, the genus Retortamonas and diplomonads formed a robust clade. Retortamonas sequences split into three host-specific lineages. The...
