Public Tenders in EU: Statistics and Overview
Kurka, Vojtěch ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
The purpose of this bachelor thesis is to provide well-arranged statistics and surveys about tenders in the European Union. Statistics and surveys are visualized as graphs, textual informations and different kinds of maps. Those statistics are based on data from corresponding EU information system and stored in MySQL database. In advance these data are offered to others in machine readable format. Easy understanding and mainly graphical representation of data is the most important part. All statistics are accessible via web pages optimized for the most common web browsers.

Aerospace - Flight Data Vizualization
Morávek, Martin ; Bartoň, Radek (referee) ; Chudý, Peter (advisor)
This thesis deals with the flight data visualization phenomena for a modern airplane cockpit. It describes the analog flight instruments and the modern `glass cockpit' displays. A signifficant part is dedicated to the design and implementation of the flight display layout for the Zlin Z-142, using flight simulator extracted data. The application was designed considerating a clear and readable form of the displayed data. Different versions are being discussed, including the final version in terms of clarity and readability of provided indicators.

Brain Signals Visualization
Ševčík, Ivan ; Drahanský, Martin (referee) ; Košík, Michal (advisor)
EEG je neinvazivní metoda pro měření mozkové aktivity, která poskytuje důležitý náhled do činnosti lidského mozku. Tato práce prezentuje aplikaci, která slouží jako vizuálni nástroj pro analýzu EEG dat. Koncept aplikace je založen na jiných existujících řešeních, které byly v rámci práce analyzovány. Aplikace kombinuje prohlížeč signálů ve formě vícenásobného čárového grafu s 2D a 3D vizualizacemi užitečnými pro rozpoznání specifické mozkové aktivity. Součásti aplikace je i sada metod pro zpracování signálu. Závěr práce je věnován shrnutí dosažených výsledků a plánů pro další vývoj aplikace.

Mathematical methods of morphology modelling of coniferous trees
Janoutová, Růžena ; Štarha, Pavel (referee) ; Martišek, Dalibor (advisor)
The thesis was focused on creation of a coniferous tree by nondestructive method allowing description of structure of adult spruce trees. After processing provided data we created a model of L-system which creates a tree branch. Thereafter, a Python script generated parameters which were required for the creation of the model of the tree in graphical software Blender. Model of coniferous tree was sucesfully generated. Its memory requirements are high but for our purposes this is not an essential problem.

Increasing the information value of the data using modern approaches to visualization
Král, Jakub ; Slánský, David (advisor) ; Pour, Jan (referee)
This thesis solves the area of data visualization in Business Intelligence. We live in a time when the amount of data grows turbulently. These data need to be processed into a form with added value for management and business objectives of the company. The first task is to adjust the data into the required format, the second task is to choose the appropriate visualization so that the data are providing the highest value. This work deals with data visualization and its main aim is to introduce a different approach to data visualization, which has a higher added value than conventional visualization methods used in dashboards and reports. First of all, theoretical part is describing data area (including the trend of Big Data) and reporting (chapter 3). Followed by chapter 4, which is enriching the reader with the information about the need to deal with data visualization and also with the design theory of visualization components. The theoretical part is finished with fifth chapter. It deals with current trends in the field of data visualization and Business Intelligence and also introduces D3.js library as a tool for creating interactive and efficient visualization components. The practical part is offering suggestions for interactive and dynamic visualization of input data (chapter 6). It presents a convenient way to choose a visualization component with greater value than the traditional static component in the form of a graph or table. Proposals contained in D3.js library are presented to the reader. Chosen components according to the author are interesting from the view of design and, if properly used, offer an innovative approach to data visualization. For purposes of practical examples of visualization, author is using D3.js library and open source tool for Business Intelligence from Pentaho. Practical example is part of the final chapter 7.

Comparison of selected commercial reporting BI platforms
Krečmerová, Petra ; Novotný, Ota (advisor) ; Daněk, Lukáš (referee)
This Diploma thesis focuses on a comparison of selected commercial reporting BI platforms. The goals of the thesis are to create pilot dashboards based on three Business Intelligence tools, compare these tools among themselves and select the most optimal one for creating dashboards. The theoretical part describes the problematics of Business Intelligence, its principles and components. These are divided into several layers such as production systems, transformation and data layers, data analysis and presentation layer. The performance dashboard are then described and an indepth analysis of the commercial tools market has been performed. In the practical part pilot dashboards are created based on retail chains data in three selected Business Intelligence tools Power BI, QlikView and Tableau. These are then compared and based on a multi-criteria analysis the optimal tool for creating dashboards is selected and recommended. The evaluation criteria, their weights using Fuller´s method and the final evaluation based on the Weighted Sum Approach are set in the analysis. The Diploma thesis is set up for a project of the Competency center Retail Analytics and for the professional community. It shall be used as one of the sources in the selection of BI reporting platform.

Digitalization and Visualization of J. A. Comenius' Correspondence (1592-1670)
Lelková, Iva
The project of digitizing and visualization of Jan Amos Comenius' (1592-1670) correspondence is an outcome of an international collaboration among the Department for Comenius Studies and Early Modern Intellectual History of the Institute of Philosophy of the Czech Academy of Sciences and the Cultures of Knowledge project of the University of Oxford. An online database of Comenius' letters was created within the online union catalogue of early modern scholarly correspondence called the Early Modern Letters Online (EMLO) and outstandingly rich metadata were used for visualizations and analysis of the Comenius' correspondence. The researchers used free visualization web-based platform Palladio developed by the Stanford University. Visualization and data analysis not only facilitated to visualize previously known tendencies and facts but also helped to discover new and unknown moments which led to further study.

JSF Framework for Complex Data Visualization
Linha, Martin ; Šlajchrt, Zbyněk (advisor) ; Vitinger, Jiří (referee)
The thesis is focused on the development of JSF framework providing components for complex data visualizations. Its objective consists of the implementation of the API for creating JSF components rendering complex charts based on the JavaScript library C3.js and subsequent implementation of a set of chart components using this API. The contribution of this thesis is a library providing a tool for creating new JSF components based on C3.js together with a set of ready to use components. It begins with research of relevant JSF libraries, following with API analysis and design. Based on that is API implemented, in which a component set is then created. As a part of this work is a user guide, API reference guide and presentation web of implemented components.
