Vliv doby působení druhého jazyka na chápání vztažných vět u dětí školního věku / Effect of time of exposure to L2 on the comprehension of relative clauses in primary school children

Brabcová, Alžběta January 2018 (has links)
This study investigates the impact of second language age of onset on the development of syntactic competence in bilinguals. Forty-five bilingual children were tested using a picture- matching task with relative clauses. In this paradigm, children are aurally presented with relative clauses of various kinds and are asked to match what they hear with the appropriate picture (out of four choices) on the screen. More specifically, our experiment compared the comprehension of subject- vs. object-extracted center-embedded relative clauses and contained sentences with noun phrases (NPs) that did or did not match in number (both NPs singular or plural = match, one NP singular, one NP plural = mismatch). We compared the performance of a group of Simultaneous bilinguals (two languages since birth), Early sequential bilinguals (first exposure to L2 - English between the ages of 1 to 4) and Late sequential bilinguals (first exposure to L2 -English after the age of 4 but latest at the age of 6 - primary school). The mean age of the participants at the time of testing was approx. 10 years of age. The results show that there is a varied pattern in the comprehension strategies used among the three bilingual groups. The group of Simultaneous bilinguals showed more reliance on the syntactic information contained in...

Klinickopatologické a molekulárně biologické charakteristiky vybraných kožních epiteliálních a neepiteliálních nádorů / Clinicopathological and molecular biologic characteristics of selected cutaneous epithelial and nonepithelial tumors

Kastnerova, Liubov January 2019 (has links)
The doctoral thesis MD. Liubov Kastnerova (previous name Kyrpychova) is focused on the histomorphological and molecular biologic features of selected cutaneous epithelial and nonepithelial tumors and is structured as a commentary to the 20 articles published during four years, representing the completed scientific projects in the Ph.D. course. In eight papers, the author of the thesis is the first author, whereas she coauthored in the remaining 12 papers. The thesis is composed of the commented files of authors own publications and it is divided into cutaneous epithelial and nonepithelial tumors. The first section, «Cutaneous epithelial tumors», includes 14 articles that are subdivided into two parts: adnexal tumors (9 articles) and lesions of anogenital mammary-like glands (5 articles). Of the nine articles on adnexal tumors, there are 5 articles focused on various benign and malignant adnexal lesions with apocrine or eccrine differentiation. Novel findings in this part include the identification of hitherto unreported alterations of the MYBL1 gene in adenoid cystic carcinoma of the skin and lack of deletion of the 1p36 locus in this neoplasm; the lack of a correlation between cellular composition and the presence CRTC1-MAML2 fusions in hidradenoma, the absence of CRTC3-MAML2 fusions in this tumor,...

Hodnocení morfologie patra u BCLP pacientů s palatoláliemi / Evaluation of the palate morphology in bilatelar cleft lip and palate clefts with palatolaly

Hamtilová, Martina January 2011 (has links)
The diploma work was based on the evaluation of dental casts of patients with bilateral cleft lip and palate (BCLP) with a mean age of 10. Patients consist of two groups, patients without defect in speech and with speech impairment (palatolaly). Palatolalies in the literature are primarily associated with velopharyngeal insufficiency. The study tested the working hypothesis that in the failure of speech is involved a different, specific in some way, palatal shape. Dental casts were scanned using a laser scanner and analyzed by 3-D geometric morphometry and multivariate statistics: principal component analysis (PCA), linear regression analysis and finite element analysis (FESA). Using linear regression it was found that the shape of the palate is affected in younger individuals by age, and so had to be 5 patients excluded for further analysis. Patients with palatolaly have lower variability the palatal shape than patients without palatolalie, so their palates are similar to each other and have a specific shape. Palates are wider and lower than in individuals without speech disorder and they have a characteristic deepening behind the anterior part of the palate. We assume that these features in palate morphology primarily the lower arch and the substantial deepening are most likely to affect the...

Analýza cytologických snímků / Analysis of cytology images

Pavlík, Jan January 2012 (has links)
This master’s thesis is focused on automating the process of differential leukocyte count in peripherial blood using image processing. It deals with the design of the processing of digital images - from scanning and image preprocessing, segmentation nucleus and cytoplasm, feature selection and classifier, including testing on a set of images that were scanned in the context of this work. This work introduces used segmentation methods and classification procedures which separate nucleus and the cytoplasm of leukocytes. A statistical analysis is performed on the basis of these structures. Following adequate statistical parameters, a set of features has been chosen. This data then go through a classification process realized by three artificial neural networks. Overall were classified 5 types of leukocytes: neutropfiles, lymphocytes, monocytes, eosinophiles and basophiles. The sensitivity and specificity of the classification made for 4 out of 5 leukocyte types (neutropfiles, lymphocytes, monocytes, eosinophiles) is higher than 90 %. Sensitivity of classiffication basophiles was evaluated at 75 % and specificity at 67 %. The total ability of classification has been tested on 111 leukocytes and was approximately 91% successful. All algorithms were created in the MATLAB program.

Překlad z češtiny do angličtiny / Czech-English Translation

Petrželka, Jiří January 2010 (has links)
Tato diplomová práce popisuje principy statistického strojového překladu a demonstruje, jak sestavit systém pro statistický strojový překlad Moses. V přípravné fázi jsou prozkoumány volně dostupné bilingvní česko-anglické korpusy. Empirická analýza časové náročnosti vícevláknových nástrojů pro zarovnání slov demonstruje, že MGIZA++ může dosáhnout až pětinásobného zrychlení, zatímco PGIZA++ až osminásobného zrychlení (v porovnání s GIZA++). Jsou otestovány tři způsoby morfologického pre-processingu českých trénovacích dat za použití jednoduchých nefaktorových modelů. Zatímco jednoduchá lemmatizace může snížit BLEU, sofistikovanější přístupy většinou BLEU zvyšují. Positivní efekty morfologického pre-processingu se vytrácejí s růstem velikosti korpusu. Vztah mezi dalšími charakteristikami korpusu (velikost, žánr, další data) a výsledným BLEU je empiricky měřen. Koncový systém je natrénován na korpusu CzEng 0.9 a vyhodnocen na testovacím vzorku z workshopu WMT 2010.

Morfologické operace ve zpracování obrazu / Morphological Operations in Image Processing

Kolouchová, Michaela January 2008 (has links)
Mathematical morphology stems from set theory and it makes use of properties of point sets. The first point set is an origin image and the second one (usually smaller) is a structuring element. Morphological image transformations are image to image transformations based on a few elementary set operators. Fundamental morphologic operations are dilation, erosion and hit or miss. Next operations described in this work are opening and closing. Originally morphological operators were used for binary images only, later they were generalized for grey tone and color ones. This work describes the basic morphological image processing methods including their practical usage in image filtering and segmentation.
