Options removal of micropollutants with water treatment processes
Zdražilová, Alena ; Bogáňová, Ida (referee) ; Biela, Renata (advisor)
This diploma thesis is engaged in problems of micropollutants removal by water treatment process. The first part aims to define single micropollutants, possibilities of their removal in laboratory and micropollutants removal on water treatment plant. In the second part, there is data evaluation of water analyses on factual water treatment plant. Also there is description and evaluation of experiment, which aims to pesticide removal from river by using filtration across granulated active carbon.

Removal of micropollutants during drinking water treatment
Císařová, Monika ; Lukášová, Daniela (referee) ; Biela, Renata (advisor)
The diploma thesis deals with the issue of micropollutants removal during drinking water treatment. The theoretical part characterizes individual types of micropollutants, their occurrence and possibilities of their removal. It also presents the removal of micropollutants already implemented in practice. The practical part deals with the removal of a selected micropollutant, namely perfluorinated substances. This is a laboratory experiment on the removal of perfluorinated substances from a given flow by filtration through granular activated carbon Filtrasorb F400. Finally, the results and evaluation of the experiment are presented.

Reflection Detection and Removal From Image Sequences
Hodaň, Tomáš ; Juránková, Markéta (referee) ; Herout, Adam (advisor)
Cílem mé diplomové práce bylo studium existujících metod pro detekci a odstranění odlesků ze sekvence snímků, nalezení jejich omezení a návrh možných vylepšení. Konkrétně jsme se zaměřili na rovinné spekulární povrchy, jejichž vzhled může být modelován superpozicí odrážené a přenášené vrstvy. Prozkoumali jsme především metody využívající vzájemný pohyb vrstev jako hlavní klíč k jejich oddělení. Popsali jsme jejich společný případ selhání, který spočívá v neschopnosti správného oddělení oblastí s nevýraznou texturou ve směru pohybu kamery. Výsledkem našeho úsilí je metoda řešící tento problém. Jejím hlavním přínosem je nový způsob odhadu hran obou vrstev, kdy důraz je kladen na správné oddělení hran zmíněných problematických oblastí. Věnovali jsme se také následnému odhadu barev jednotlivých vrstev, kdy se vedle hran vrstev využívá i odhad jejich hloubkových map, a popsali jsme alternativní přístup ke klasické kvadratické optimalizaci.

Removal of phosphorous at constructed treatment wetlands
Štěpáníků, Alex ; Mrvová, Michaela (referee) ; Pumprlová Němcová, Miroslava (advisor)
This Bachelor thesis deals with issues of the removal of phosphorus in constructed (treatment) wetland. The main purpose of this thesis is to make literature review with focus on different technology of the removal of phosphorus from small community waste water treatment plants and evaluate their appropriateness for usage in constructed (treatment) wetlands. Sub-chapters deal with the topic of constructed (treatment) wetlands with a focus on the removal of phosphorus in broader context. The result of this thesis is recommendation for specific technological solutions, that could be used in constructed (treatment) wetlands. Part of this thesis is practical example of the design of selected technology for the removal of phosphorus for a real constructed (treatment) wetland.

Eliminator of dental calculus
Halaš, Rostislav ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
Tato práce se zabývá návrhem ultrazvukového odstraňovače zubního kamene pracujícím na frekvenci 27 kHz s maximální intenzitou ultrazvuku 5W/cm2. Popisuje mechanismus vzniku zubního kamene, důsledky na zdraví a metody jeho odstraňování. Zaměřuje se na principy odstraňování s využitím ultrazvukového vlnění. Dále je sestaveno funkční a blokové schéma. Na základě těchto znalostí je proveden návrh a výpočet jednotlivých částí aplikátoru. Výkonové a napěťové poměry jsou vypočítány od aplikačního hrotu směrem ke generátoru. V neposlední řadě je popsán návrh obvodů buzení měniče i kontrolních obvodů. Schémata jsou doplněna výkresy desek plošných spojů a soupiskou součástek.

Modification of ceramic shells to increase its break up after casting process
Škriečková, Natália ; Horáček, Milan (referee) ; Krutiš, Vladimír (advisor)
This master´s thesis deals with the problem of the disintegration of shell moulds after casting. Too high residual strength increases the cost of operations associated with the final cleaning of castings. The aim was to analyze the current state of the art and to optimize the production of moulds in MoraviaTech a.s. so that the removal of the ceramic shell after casting is easier. In the first part, a literature analysis of the influences that could have a positive effect on the speed of shell removal is made. In the practical part, experiments are conducted comparing the amount of shell removed as a function of time between modified ceramic shells and shells produced by the company. In the last part, the results of the individual measurements are evaluated and conclusions and recommendations for MoraviaTech a.s. are drawn from them.

Posouzení dynamiky růstu a šíření jmelí bílého (Viscum album) na vybrané lokalitě
Horký, Jan
This thesis deals with growth dynamics and spread of white mistletoe (Viscum album) in the so-called „Fisherman's Alley“ in Přerov in 2021 and 2022. The research maps the degree of mistletoe infestation and basic characteristics of trees and examines their relationships. It also observes the relationship between mistletoe growth and climatic variables and maps the methods of mistletoe removal in the Czech Republic. In the observed period, the mistletoe infestation intensity increased in 22% of trees. The height and circumference of the tree affect the degree of infestation, the effect of age and health of the tree was less significant. The work showed a slight correlation between minimum temperatures in the first quarter of the year and mistletoe growth. The public administration is mainly involved in the removal of mistletoe in the Moravian-Silesian and Zlín regions, where pruning or felling trees are the most common methods. Chemical treatment usage is beginning to be used step-by-step.

Odsun - vyhnání českých Němců z Kaplicka pohledem pamětníků
MUSILOVÁ, Tereza
This thesis follows up the topic of removal - expulsion of Czech Germans living in Czech borderland after the Second World War and it surveys the process of forced displacement in Kaplice and its surroundings in South Bohemia not only with provided data, but mainly with concrete stories. The Theoretical part focuses on the coexistence of Czechs and Germans in Czech territory and describes given historic circumstances which led to its bitter end. It endeavours to outline the process of removal and its consequences for Czechoslovakia. In the Practical part, the concrete stories of contemporary witnesses of the forced displacement complement the information about the process and consequences related to South Bohemian borderland. The main aim of this thesis is to ascertain what the contemporary witnesses think of this affair today.

History of Czech primary school in village Kájov
MÜLLER, Martin
This bachelor thesis describes the history of the Czech elementary school in Kájov from its founding till 1950. The thesis focusses on the Czech school but at the same time is related to the German schooling. I have worked with on-line accessible school chronicle from The State Regional Archives in Třeboň, but also with non-published memories from family members of Růženka Hotová, the contemporary witness of Kájov. The thesis is focused on Kájov, from its history until the present day, establishment of the education system, Nazi influence, wartime, removals of German inhabitants after the World War II and arrival of communism until 1950. One of the reasons is that lots of materials from that times are accessible and also the importance of mentioned occurrences for Czech people.
