Processing of EEG signals in frequency domain
Nováková, Jarmila ; Potočňák, Tomáš (referee) ; Kozumplík, Jiří (advisor)
Sleep EEG is occupied by this project. It is aimed at processing signal which precede test of stationarity. It also deals with the issue of stationarity of sleep EEG with indicating of three types of segmentations. Principles of three types of segmentation are explained and their realization is compiled in the environment of Matlab by the way which enables to choose different input parameters. The change of stationarity is examined in various stages of sleep with the help of the results thus created functions. Another aspect of this study is the investigation of changes in the development of absolute and relative power over time according to transition between stage of wakefulness and stage of sleep. It is searched for the occurrence of these changes also in the development of the coherence spectra.

Complex conjunctives and their impact on cohesion and coherence in upper-secondary students' semi-formal essays
Kloučková, Julie ; Pípalová, Renata (advisor) ; Nádraská, Zuzana (referee)
The thesis aims to explore the usage of complex conjunctives in upper-secondary students' semi-formal essays. It deals with written discourse produced by two groups of students of B1 and B2 (CEFR) levels, uncovers the differences in their use, explores their impact on cohesion and coherence and looks at the students' understanding of these concepts. In total, 40 essays in two B1 and B2 subcorpora are analysed through a corpus analysis tool inspired by the framework of Halliday and Hasan. Prior to that, analyses of writing sections in three students' books from the perspective of Teachability Hypothesis and Processability Model are conducted to establish the potential frequency and conjunctive type scale. Both qualitative and quantitative analyses showed that upper-intermediate students employ more complex conjunctives than intermediate students, even though the difference is not substantial. The data also indicate that both groups prefer initial sentence placements to the medial positions, and that additives are used over adversatives. Furthermore, the analyses uncovered surprising results, for example, in the area of paragraph-initially and paragraph- internally used conjunctives. The research shows that complex conjunctives are essential in semi-formal and formal writings and that especially...

Functions of professional scientific discourse
Kis, Mátyás András ; Baumgartnerová, Alena (referee) ; Krhutová, Milena (advisor)
Teoretická část této práce se komplexně zabývá různými aspekty analýzy diskurzu, zahrnujícími definice diskurzu, metodologie analýzy, situované významy, kohezi, koherenci a rozdíly mezi mluveným a psaným jazykem. Práce zdůrazňuje složitou povahu jazyka a zdůrazňuje, že efektivní komunikace přesahuje pouhou gramatickou přesnost. Zahrnuje porozumění kontextu, uplatňování pragmatických strategií a obratné používání různých řečových aktů k dosažení přesných komunikačních cílů. Práce dále zkoumá pojem řečových aktů, jejich rozmanité typy a jejich mnohostranné funkce v rámci různých jazykových stylů, zejména v oblasti vědy a techniky a populárně naučného stylu. V následujícím segmentu práce se studie hlouběji zabývá konkrétními řečovými akty, které se běžně vyskytují v oblasti angličtiny v elektrotechnice. Jedná se o tyto řečové akty: explikace, exemplifikace, hodnocení, argumentace, definování, vyvození závěru a kritika. Co se týče praktické části práce, analyzuje příklady technických a humanitních textů, které odpovídají různým řečovým aktům, jež byly zkoumány v teoretické části.

Traumatic Events: A Linguistic Perspective
KREJČOVÁ, Eliška
The goal of the thesis is to examine traumatic events from a linguistic perspective in detail. People who talk about their traumatic experiences use language in a specific way, and others who are a part of the conversation should adapt their expectations accordingly. Therefore, the thesis will mainly focus on what the discourse of traumatic events looks like and how we use narrative and other linguistic phenomena when it comes to this area. This information will be used to describe how we should try to perceive people with traumatic experiences and how to interpret their utterances. Both theoretical and applied linguistics will be used to achieve this goal, as well as interdisciplinary fields such as psycholinguistics. The thesis will then also work with sources from the areas of law and psychology. It will examine court cases connected to witness accounts of traumatic events and also psychological handbooks which deal with this phenomenon.

Comparative analysis of professional texts on computer science
Chufarov, Evgeny ; Sučková, Magda (referee) ; Zmrzlá, Petra (advisor)
Cílem této bakalářské práce je srovnávací analýza odborných textů z oblasti informatiky. Jako téma pro materiály byla zvolena technologie VxLAN, která je nejčastěji používána v datových centrech. Prvním textem pro analýzu je článek z webového časopisu, druhým je technická dokumentace Request for Comments (RFC), třetím je video přednáška. Hlavním cílem této práce je prozkoumat vybrané materiály z různých pohledů a určit, do jaké míry se texty, psané a mluvené, liší v použití jazyka a jaké jsou jejich společné rysy. K dosažení tohoto cíle jsou materiály zkoumány z hlediska několika diskurzních rysů, mezi které patří funkce jazyka, styl a žánr, koheze, koherence a deixe. Práce se také zaměřuje na zjištění, zda jsou analyzované materiály typickými představiteli svých žánrů a stylů.

Study of the effect of migrastatics on the dynamics of tumour cell migration using a coherence-controlled holographic microscope
Muchová, Nikola ; Netíková,, Irena Štenglová (referee) ; Veselý, Pavel (advisor)
The thesis is focused on the exploitation of the coherence controlled holographic microscopy for the investigation of the influence of the supposed migrastatic drugs on the dynamics of cancer cell migration. The theoretical part briefly describes the history of holographic microscopy and the development of the holographic microscope at the Brno University of Technology in collaboration with Telight, Brno, including an insight into the design and principle of operation of the coherence-controlled holographic microscope. Next a brief description of current cancer treatments introduces new class of anti-cancer drug candidates designated migrastatics that should impair cancer cell migration and thus prevent late metastases formation. The main part of the thesis deals with the design of the experimental observation procedure and data processing using the holographic incoherent Quantitative Phase Imaging technique. The last part of the thesis is the subsequent analysis of the migrastatic effect of the selected drugs on cancer cells in vitro and the comparison of the obtained results with existing studies. Finally, the objectives with magnification 4x and 10x were evaluated and compared for starting “the Rapid Assessment of Cell Growth and Migration”.

Selected aspects of radio programmes on cooking
Jelínková, Blanka ; Andrlová Fidlerová, Alena (advisor) ; Adam, Robert (referee)
This thesis discusses selected linguistic aspects of two radio culinary broadcasts (Rozhlas u plotny, Pochoutky). The theoretical part deals with the tradition of spoken language research, its resources and the phenomena studied. The conclusion of this chapter is devoted to the approaches to spoken language focused on coherence and cohesion. For the purposes of analysis, transcripts of above mentioned radio culinary broadcasts were made. Specific transcription rules (based on different existing transcription rules) were created, to suit our type of analysis. In Rozhlas u plotny, the guest is a professional chef, in Pochoutky, the guest is an actor or a presenter. First part of the work briefly describes and compares language of these two types of speakers in the terms of phonetics, morphology, lexicology, syntax and stylistics. Subsequently, the main part of the thesis concentrates on textual syntax and describes cohesion and coherence of spoken dialogue. From this point of view, it focuses on comparison of two types of dialogues (and two types of speakers): predominantly continuous dialogue vs. predominantly interrupted dialogue (e.g. by overlapping talk). Thus, it gives examples representing various ways of retaining cohesion and coherence in continuous dialogue and in interrupted dialogue. Key...

Paragraph as a Cognitive Unit of Non-Literary Texts
Obdržálková, Vanda ; Králová, Jana (advisor) ; Eichl, Radek (referee) ; Aurová, Miroslava (referee)
The present thesis analyses the paragraph structuring of non-literary texts in Czech and Spanish and in translations from Spanish into Czech. Paragraph has been defined as a textual and cognitive unit, which is characterized by a unity of topic and inner coherence and plays an important role in text production and interpretation. The central part of the thesis presents the results of an empirical analysis of three groups of non-literary texts consisting in a three-stage comparison of comparable and parallel texts. The first aim of the analysis is to detect whether there are any culture-bound differences in paragraph length and thematic structure between comparable Spanish and Czech texts. The quantitative analysis was also focused on average length of sentences. The second aim is to describe the translators' approach by comparing the translations with their respective originals. Subsequently, the translations were compared with comparable original Czech texts. Based on this comparison it has been determined to what extent the translations are oriented towards the pole of adequacy (reflecting the values of the source language), or on the contrary, towards the pole of acceptability (reflecting the values of the target language). A translation analysis attempts to describe the factors influencing the...

Discourse Relations in Czech
Poláková, Lucie ; Hajičová, Eva (advisor) ; Hoffmannová, Jana (referee) ; Pešek, Ondřej (referee)
This doctoral thesis is devoted to linguistic analysis of discourse relations as one of the aspects of discourse coherence. Discourse relations are semantic relations holding between propositions in a discourse (discourse arguments). The aim of the thesis is a complex description of discourse relations in Czech and its application in an annotation scheme in the Prague Dependency Treebank. The thesis is divided into three parts: The first one is focused on the theoretical description of discourse relations and on analysis of adequacy of various methodological concepts in corpus processing. The second part describes in detail the proposed scheme for the annotation of discourse relations and the process of the corpus build- up including the evaluation of consistency of the annotated data. Finally, in the last part of the thesis, we address some problematic issues arisen with the employment the proposed scheme and look for their possible solutions.
