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.

Prevention of defects during tube bending
Procházka, Libor ; Štroner, Marek (referee) ; Peterková, Eva (advisor)
The bachelor thesis describes the most occurring defects of tube´s component bending. The first part of this thesis is focused on a detailed research of these unwanted phenomenons. The second part contains complete list of possibilities in the defects reduction. There are quoted the suitability and the terms of use for an individual eliminative methods in the second part of this thesis, too. The last part of this bachelor thesis contains classifying of elimination possibilities to the particular types of defects.

Removal of Anesthesia Tube from Pediatric CT Data
Šejnohová, Marie ; Čmiel, Vratislav (referee) ; Walek, Petr (advisor)
The goal of this semestral thesis is to detect and subsequently to eliminate an anaesthesiological tube from a pediatric CT data using a Hough transform. It describes particular edge detectors based on the first and the second differences. In addition, it explains a principle of the edge detection using to this detectors. Then there is talked about the Hough Transform where is described a parametric space for lines and circles detection. Here follows a description of image to the parametric space. In a practical part there is implementation of the edge detection and the Hough transform. The Hough space must be normalized to better evaluation. At the evaluation there are found a concentric cicrles corresponding with edges of an anaesthesiological tube which is then possible to remove.

Methods of removing persistant polutants (dioxins)
Ferdan, Tomáš ; Jecha, David (referee) ; Pařízek, Tomáš (advisor)
The bachelor‘s thesis deals with rise of dioxins in waste-to-energy system in municipal waste incinerator and with technologies for their removal. The thesis speaks commonly about characteristics of dioxins and about their influence on environment and health in the first part. Furthermore are outlined the ways of dioxins production and the emission limits for off-gas. The second part of the bachelor’s thesis includes description of commonly used methods for removing dioxins from off-gas. There are mentioned their main advantages, disadvantages and compared efficiency of individual methods.

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.

Odstranění rozmazání pomocí dvou snímků s různou délkou expozice
Sabo, Jozef ; Šroubek, Filip (advisor) ; Horáček, Jan (referee)
In the presented work we study the methods of image deblurring using two images of the same scene with different exposure times, focusing on two main approach categories, so called deconvolution and non-deconvolution methods. We present theoretical backgrounds on both categories and evaluate their limitations and advantages. We dedicate one section to compare both method categories on test data (images) for which we our MATLAB implementation of the methods. We also compare the effectiveness of said methods against the results of a selected single-image de-noising algorithm. We do not focus at computational efficiency of algorithms and work with single-channel images only.
