Contour Shape Classification for Detection of Mis-Segmented bones in CT Data
Janovič, Tomáš ; Jan, Jiří (referee) ; Walek, Petr (advisor)
The thesis discusses the possibilities of using contour shape classification for detection of mis-segmented bones in computed tomography (CT) data. In the first part there are presented published methods and algorithms which deal with the segmentation of bone structures in CT data. Then segmentation of cortical bones is implemented by a simple thresholding with global threshold. The threshold is determined by the optimized fitting of a selected type probability distribution to the histogram. Subsequently, the thesis describes some important shape descriptors that can quantitatively describe the shapes of objects in the image. Further, the contour extraction is implemented and a suitable shape descriptor, cumulative angular function, is applied. Finally, the points which can potentially indicate mis-segmented bones are detected by using continuous wavelet transform. The proposed technique is tested on the real CT data.

Cluster analysis as a tool for classification of objects
Budilová, Šárka ; Löster, Tomáš (advisor) ; Šulc, Zdeněk (referee)
Cluster analysis is a popular method of multivariate statistics. Based on mutual similarities between objects this method is able to classify and divide objects into several groups or clusters. The results of the clustering can be different by using different methods, measures of distance and procedures. The main aim of this thesis is to compare the results of several methods of cluster analysis with the known classification of classes from the original data file. In total, there are 15 data files, which were analyzed and each of them contained known information about the right allocation of objects in groups. The success of clustering of each method was calculated by comparing the known classification of classes and resulted clusters. In addition to the comparison of individual methods of cluster analysis was compared the impact of standardization and correlation to the success of each method. To reflect the distance betweeen the objects within each clusters, squared Euclidean distance was used. The results of this thesis point out that better success of clustering were achieved in the case of correlated variables in data file. The succes of clustering was higher about 2 percent points than in the case when correlated variables were deleted from data set. The methods divided 69,8 % objects before standardization and 70,8 % objects after standardization. The results also show a large importance of standardization in the case of Ward´s method. After standardization this method rank the most objects into correct classification classes and were more succesful, about nine percent points. In the case of correlated variables is the succes of the method 76,4 %. Standardization positively influences also centroid method and the method of farthest neighbour. Median method, nearest neighbour method and the method of average linkage achieve higher success of clustering in the case of original, nonstandardized variables (uneven variables).

Multiple sclerosis detection
Kopuletý, Michal ; Mangová, Marie (referee) ; Uher, Václav (advisor)
This thesis is focused on detecting multiple sclerosis lesions from magnetic resonance images. Correctly retrieved lesions are very important for medical diagnosis. Detection of lesions using machine learning techniques is quite challenging because of large variability in size, shape and position of lesions in the brain. In the practical part is designed base software, which after completion will classify pixels, so that is possible to find lesions of multiple sclerosis. For classification will be used Support vector machine. Theoretical part describes multiple sclerosis, basic operations performed with biomedical images and data classification.

Swimming for disabled children in České Budějovice and in Jihlava
TRINGLOVÁ, Lenka
Abstract The bachelor thesis, which is called {\clqq}Swimming for children with disability in České Budějovice town and in Jihlava town`` is aimed to a swimming realization for the children with disability in the civic associations named KONTAKT without barriers (hereinafter only: KONTAKT wB) and Vodomílek Sport Club (hereiafter only: Vodomílek SC). The theoretical part characterizes an impact of the water surroundings, the importance and the use of swimming for the children with disability. Furthermore the hydrotherapy, the hydro-kinesiological therapy, the suckling swimming and the swimming classification are specified in that part. The aim of my work has been to find out, how the swimming for the children with disability in both the already mentioned associations is realized. The aim was reached by means of a structured conversation to parents and to the children from KONTAKT wB and from Vodomílek SC, and also by means of semi-structured conversations to specialists of the given sphere. Furthermore the research was completed by watching of the children with disability during their swimming lesson. Comparison of the theoretical part and the practical part show the swimming itself enables the children with disability their multilateral development and it increases their self-activity. It also contributes to their socialization and to their resocialization. It teaches the human being to get to know himself, his body and his possibilities. Furthermore it increases his fitness and his organism resistance. It is proved the swimming lesson realization in both associations corresponds to the parents´ideas of the children with disability. The swimming itself is mainly realized by volunteers, who have to be empathetic, persevering and firm. That can also be practised by the parents themselves last but not least. It is clear from the results that the way of the swimming realization in KONTAKT wB and in Vodomílek SC is not the same. The common feature is their individual approach to the children as well as their typical swimming lesson configuration. The difference rests in the teaching method, which both the associations purvey. KONTAKT wB proceeds according to their own methodical line, Vodomílek SC combines various teaching methods. Results of that research will be used as the better understanding of the swimming purpose for the children with disability and will help promote that sports activity. The theoretical part and the research can be used as the knowledge summary related to problems of the children with disability. It can be used by parents, volunteers, swimming coaches and others, who want or need to get more detailed pieces of information related to that theme.

Molecular Phylogeny, Biology and Classification of the Microsporidia (MIcrosporidia, Fungi) According to the Model Groups from Caddis Flies (Insecta, Trichoptera) and Butterflies (Insecta, Lepidoptera)
Hyliš, Miroslav
Twenty-four microsporidia from Trichoptera and Lepidoptera as well as 5 microsporidia from potential intermediate hosts (Crustacea, Amphipoda) were isolated and screened using light and electron microscopy and molecular biology methods. The screened organisms represented the following genera in the conventional classification of Microsporidia (Canning and Vávra, 2000) Nosema (7), Endoreticulatus (3), Cystosporogenes (2), Thelohania (4), Gurleya (1), Cougourdella (1), Pyrotheca (1), Episeptum (5), Toxoglugea (1), Larssoniella (2), unresolved isolates (2) (the number of species examined in respective genera is given in parentheses). The publications report the ecological and experimental data on the prevalence, host and tissue specificity and transmission. All studied microsporidia from Trichoptera beloning to genera Episeptum, Paraepiseptum n.g., Zelenkaia n.g. are host-species specific parasites infecting fat body and oenocytes of their hosts. Their spores are not infective for the original host, their life cycle involves probably an intermediate host and (or) transovarial transmission. Data obtained by rDNA sequencing showed that microsporidia (genera Thelohania, Gurleya, Toxoglugea) from several of Gammarus spp., occurring sympatrically with Trichoptera are not involved in the life cycle of...
