Prostorové dělení optických svazků / Spatial Division of Optical BeamsHampl, Martin January 2009 (has links)
The dissertation thesis deals with a free space optical links, especially is focused directly to the transmission optical beams. The influence of environmental conditions like atmospheric turbulence, buildings movement and vibration is described. As a possibility to reduce these undesirable influences, the generation of the transmission beam by the help of the two-mode optical fiber is proposed. A possibility to drive the shape of the resulting transmission beam by means of the change of power ration of individual modes in fiber is described. The coherence features of the proposed beam are analyzed considering the possibility to reduce the influence of atmospheric turbulence. In the thesis there are introduced beam quality parameters that enable to evaluate the quality of the optical beam for the free space optical link. These parameters give the relationship between the shape of the optical beam and the power balance of the optical link and the statistical evaluation of the optical link.

Rozdíly v hodnocení kvality tlumočení / Differences in evaluation of the quality of interpretationPospíšilová, Lenka January 2015 (has links)
Our theoretical-empirical thesis is dedicated to differences in the evaluation of the quality of interpreting. In the theoretical part of our thesis we describe representative studies in aforementioned field and their conclusions. We use them as a basis for the hypothesis of our own research in which we suppose that the formal aspect of an intepreter's delivery will influence the overall evaluation of the quality of his rendering and will be perceived by the respondents as a more important criterion than the logical cohesion of the speech. In the empirical part of our thesis we describe the design and development of our experiment. In this experiment different groups of respondents evaluated nine videos of an interpreter's rendering conducted under specific parameters defined beforehand. Subsequently we evaluate conclusions of our basic and test research. We conclude our work with a partial confirmation of our initial hypothesis.

Polarizace USA v Kongresu: Role stranických členských sdružení ve Sněmovně reprezentantů / U.S. Polarization in Congress: The role of Congressional Member Organizations in the House of RepresentativesHodboď, Dominik January 2018 (has links)
This thesis aims to contribute to the current academic debate on contemporary polarization in the U.S. Congress. The paper provides a brief overview of the relevenat existing literature and schools of thought on the issue. As part of the thought direction which steers away from definining roots and causes of polarization among the general public but rather sees them as issues of the political elite, this thesis highlights the need to focus on individual Congressional Member Organizations (CMOs) in the House of Representatives and their connection to polarization. By applying an existing dataset accepted among political science scholars as the key tool for measuring polarization, the thesis seeks to affirm the presumed ideological differences among the individual CMOs (or caucuses). The main part of this thesis which adds value to further discussion is the case study of all roll call votes of the 114th House of Representatives examining voting cohesion of the studied caucuses. The aim of this study is to show to what extent the CMOs are in fact consistent voting blocs and how influential they can potentially be within the political elites in the House of Representatives and to what level they may be contributing to the contemporary polarization.

Analýza problematických míst při zvládání matematiky u žáků s poruchou autistického spektra (a jejich vztah ke kognitivnímu zpracovávání žáků) / Analysis of Solving Math Problems in Students with Autism Spectrum Disorder (and its relation to cognitive processing of students)Sotáková, Hana January 2019 (has links)
The dissertation thesis addresses the topic of mathematical tasks processing in students with autism spectrum disorder (ASD) and problematic points of their solution. The aim of this work is to delineate methods that ASD students use to approach these tasks and solve them. We focus primarily on whether it is possible to identify different procedures than those used by typically developing students, and whether these procedures show specifics corresponding to distinct cognitive processes. In the theoretical part we provide a theoretical background for the study. Firstly, we create a frame to understand the complexity of autism, furthermore we deal with psychological theories examining the topic, and describe specifics of development of ASD students during their adolescence. Thereafter, we reflect on studies addressing mathematical skills of ASD students. Mathematics is considered as their great strength, however is not sufficiently scrutinized, as highlighted by various international studies (for example Oswald et al., 2016). The empiric part is based on qualitative methodology and pursues comparisons of mathematical tasks processing between six ASD students and typically developing peers. We strive to document differences and common points in solutions as well as to analyze cognitive processes of...

Mikroskopie časově proměnných biologických objektů / Microscopy of Time Variable Biologic ObjectsUhlířová, Hana January 2010 (has links)
The subject of the PhD thesis is the application of a transmission digital holographic microscope (DHM) which was designed and constructed in the Laboratory of optical microscopy at the IPE BUT for the research of live cells dynamics. First part of the work is concerned with theoretical description of the microscope imaging properties dependent on the coherence of illumination. It is supplemented with experiments of imaging of a model and a real biological specimen. The following part describes construction modifications and innovations of the microscope and its equipment that enabled the utilization of the microscope for live cells observations. In the experimental part the methodology of live cells preparation and DHM imaging was worked out. The methodology was verified by the observation of cell dynamics during an apoptosis induced by the cytostaticum cis-platinum. Further experiments examined the dynamics of live cells in standard conditions and during a deprivation stimulus. A novel method of holographically reconstructed phase, named \uva{dynamic phase differences}, was set up to evaluate quantitative changes of cell mass distribution during the experiments. Depending on the degree of malignancy and density of cell outgrowth, various schemes of cancer cells behaviour during a specific reaction were revealed using this method. For the quantitative analysis of the DHM phase imaging, a suitable statistical characteristic and an interpretation of the measured data were proposed. Both of them were successfully applied for the comparison of cell motility of two cell types: parental and progeny cell lines. On the basis of the proposed processing, hypotheses describing the reaction mechanism of tumour cells to stress life conditions were established. In the conclusions we summarize our findings and suggestions for the construction and the applications of a new generation of the transmission DHM.

Integrace klimatické politiky do vybraných obchodních dohod Evropské unie / Climate Policy Integration in the EU's Trade AgreementsSochor, Jan January 2020 (has links)
This master's thesis deals with climate policy integration in two European union's trade agreements, EU-Canada Comprehensive Economic and Trade Agreement (CETA) and EU-Japan Economic Partnership Agreement (EPA). Ambitions of EU's climate policy have grown in recent years. Therefore the EU needs to cooperate with other world countries to tackle the climate change now even more than ever before. One of the solutions for such a binding cooperation to fight climate change could be implemented through the EU trade policy. This master's thesis is therefore interested in climate policy integration concerning the policy coherence during the process of making trade agreements and also in climate policy aspects of the final form of the agreements. In the theoretical part, this thesis describes the academic debates of policy coherence, climate policy actors in the institutional framework of the EU and also the history of EU's climate policy. Research operationalises the academic concept of climate policy integration (CPI) and carries it out through analysisand comparison of official EU's institutional documents. In the final part, this master's thesis draws its conclusions mainly from comparison of EPA and CETA.

The thesis is deal with Czech-Islamic marriages from the viewpoint of gender. The first part characterises the basic concepts, marriage traditions in a purely Czech society, the issue of gender in the Czech marriage, marriage traditions in a truly Islamic society, Islamic marriage, gender issues, gender issues in Czech-Islamic marriage, the ethical impact of migration, including the ethical impact of cultural migration, potential misuse of the Institute to ensure family reunification residence permit in the Czech Republic, an example of migration, with specific policy approach in France. The practical part includes a rationale for selecting the research sample, showing the chosen research methodology. Based on the interviews is confirmed by the hypothesis of the thesis that the cultural influence of gender, as a bearer of a different conception of the of man-woman gender in Islamic culture, and Czech, respectively. Czech-Islamic marriages is a significant factor in causing marital disharmony. Mutual two-way cultural knowledge, as well as the presence of tolerance, love and truth, is a prerequisite to guarantee the functional relationship. This fact is verified by the Czech-Islamic couple, in the final case report.
