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.

Choroby a vady vín, jejich prevence a odstranění
Reichmannová, Šárka
This thesis focuses on defining basic defects and diseases of wine. It introduces factors affecting quality of produced wine following by definition of the basic terms such as defects and disease of wine. Particular defects are described and their causes listed, and the changes of defected wine are described in the area of aroma, taste and appearance. By each particular defect or disease there are suggestion how to prevent them and also there are mentioned methods to eliminate these defects and diseases with focus on presenting the up to date trends.

Choroby a vady vín, jejich prevence a odstranění
Čačíková, Lucie
The purpose of this thesis is to analyse and discuss the problematic of present-day wine diseases and defects as discussed in specialized Czech and international literature. Moreover, it describes the origins of various defects of wine under aerobic and anaerobic conditions caused by bacteria, yeast or even lack of compliance of hygiene in winery procedures. Different ways of prevention of these defects and possibilities of their elimination are mentioned here as well.

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.
