Numerická simulace a vizualizace vytváření syntetizovaného proudu
Trávníček, Zdeněk ; Vogel, Jiří ; Vít, T.
The paper presents the results of numerical and experimental investigations of a synthetic jet generation. The experiments were performed in air by means of flow visualization and hot-wire anemometry. The subsequent numerical simulation was performed using the commercial code FLUENT. The geometry, boundary conditions, and material properties of the numerical simulation were defined according to the real experimental situation.

Diagnostic of musical appreciation of primary school's pupils. Comparison of auditory and audio-visual versions of the tests
Vachudová, Eva ; Váňová, Hana (advisor) ; Jenčková, Eva (referee) ; Slavíková, Marie (referee)
The thesis deals with the possibilities of the measurement of the musical abilities and skills of the pupils through the collective tests of musicality. The test was prepared in two version. The first was "classical" - only auditive, but the second version was "experimental", it use the visualization in all subtests. Following a concise overview of the several tests of the musicality for last 100 years, the author defines the fundamental terms as musicality, musical abilities and skills, test, visualization. Following this introduction, she concentrates on the methodology of the construct of the tests for pupils of 1st , 4th and 6th classes of the primary school. The most extensive section of the thesis is devoted to the evaluation, description and interpretation of results of both versions of tests in several classes with use of many tables and graphs. This research verified most of hypothesis and confirmed the needfulness of the utilization of visualization not only for the testing procedure, but also for the teaching of music education in school. The interconnection of visual and acoustic perception helps pupils to understand subject matter faster and easier and also concretizes abstract musical concepts, what is necessary in case of younger age above all. 1 1 1 1 1 1

Suicide and Self-Sacrifice
Růžičková, Lucie ; Halama, Jindřich (advisor) ; Keřkovský, Pavel (referee)
Annotation: The topic of my thesis is 'suicide' and 'self-sacrifice'. The main target of the paper is to become familiar with the terms 'suicide' and 'self-sacrifice' and to find a difference between the two terms with reference to the ethical assessment. The paper has two theoretical parts. In the first part I briefly define terms 'suicide' and 'self-sacrifice' based on literature exploding some common myths and I present medical, psychological, sociological and theological knowledge on the subject. I also study historical, as well as cultural development of a suicide classification, methods, forms and means of the suicidal act and its specifics according to age, gender and different motives. The second part of the paper is dedicated to the Jan Palach case. In this part, I am trying to answer the question of whether the Palach's act is to be considered a suicide or self-sacrifice and I am also considering its ethical acceptability. I am examining motives of Palach's act, his life story, conducts and opinions, and I am dealing with responses of contemporary as well as present authors and the church representatives. At the same time, I also carry on my own critical evaluation and I am trying to answer the question whether the Palach's burn-to death act is for me an acceptable form of a ...

Volume Visualization of Human Skulls
Hrinčár, Vladimír ; Pelikán, Josef (referee) ; Maršálek, Lukáš (advisor)
Volume visualization is an important tool for exploration and understanding of complex 3D scientiffic data, as those acquired for example by CT scanning. Recent advancements in hardware and software renewal interest in interactive, high-quality volume rendering as it now becomes feasible even on desktop computers. In this work we present new application designed for visualization of CT scans of human skulls. We focus on image quality and add new features for skull comparison and di®erence visualization. Our solution is based on .NET application, which provides user interface(GUI) and external volume renderer as dynamic link library. We have implemented complex renderer for high-quality isosurfaces using algorithms based on interactive ray-marching methods including self shadowing and transparency. We also add support for multiple volumes and introduce new rendering modes for difference visualization. In addition our system uses NVidia CUDA technology, showing how to harness the power of modern GPUs for accelerating this complex task. Our results show that we are able to deliver interactive visualization tool, which can greatly help in areas like anthropological research.

Self service BI in the marketing department of a telecommunications company
Prchal, Tomáš ; Pour, Jan (advisor) ; Stecenková, Marina (referee)
This bachelor thesis describe ways of dealing with self-service business intelligence in the marketing department of a telecommunications company. The main objective of this thesis is to introduce technologies for self-service business intelligence, which are part of the program Microsoft Excel 2013 and demonstrate their potential use for the needs of the marketing department. The first part describe the theoretical side of the business intelligence with the division on the classic approach and on self-service. It is later complemented by the introduction of tools for self-service business intelligence contained in Excel. The second part is devoted to practical solutions. Firstly, dimensional model of the available data and secondly, build self-service solutions using the tools in Excel. These are the PowerPivot and Power Query, which is used primarily for the acquisition and management of source data, but also offer a basic visualization. For outputs are then used tools Power View, which allows a clear view of the required information and add-on PowerMaps, which displays the source data on a map. The output is then specific self-service solutions created according to specifications from employees of the marketing department, showing the required information through self- service tools.
