Influence of boundary walls on the flow from the ventilation outlet
Molčan, Filip ; Jícha, Miroslav (referee) ; Jedelský, Jan (advisor)
The goal of this work is to experimentally assess the influence of limiting walls of Škoda Octavia 3 automobile cabin to the air jet flowing from the right-front situated automotive vent which is part of a car dashboard. The experiment is performed by the smoke visualization method. There is a single construction option measured for an experiment. The setup of the vanes direction and the air flow rate are modified for this option. The experiment is divided into two phases. In the first phase, the visualization of the free air flow is conducted. In the second phase, exit plates are constructed and consequently, the visualization of the wall-jet flow is conducted. The results of both are compared to each other. The results imply that the influence of the surrounding surfaces must be taken into account with the increasing flow rate for the vanes set in the direction of upper-right, middle-right, and middle-middle. There is a direct interaction between the flow and exit plates (the flow impact, the Coanda effect). The free flow does not contain the information about the mutual interaction between the flow and the exit plates, as it is in the case of the wall-jet flow. In the case of the wall-jet flow, the opening of the flow takes place due to the effect of the impact and the subsequential suction caused by the Coanda effect. The exit plates substituting the car dashboard and the front window contribute to the prevention of the air intake from surrounding space and consequently to earlier flow opening from the vent. The present work also contains the measurement methodology and the image evaluation, the comparison with previous free flow measurements (70% match) and the comparison to the measurement of hot-wire anemometry method.

Analytical Dashboard for Indoor Locating System
Petrovič, Lukáš ; Ščuglík, František (referee) ; Veselý, Vladimír (advisor)
The main purpose of this work is to create an application which will provide visualisation of historical data from position sensors. The data are being obtained from closed spaces, for example shops, gymnasiums or halls. These data are valuable but without easily usable visualisation they will lose their potential. Right visualisation allows user to better evaluate situation which the data represents. Result of this work is a tool with which the user is able to easily analyse data gained in certain time interval. For the needs of analysis, the application provides various kinds of data representations, which assign the data specific purpose. Data might be presented in graphs for example for the purpose of representation of the total overcomed distance of monitored object. They can also be used in maps which provide good representation of positions due to monitored area. All created visualization elements are put into interactive blocks. These blocks make up almost whole control panel. It is easy to manipulate with these blocks and to edit created visualisation with their help.

Design and implementation of dashboards within Business Intelligence or a paper mill
Kos, Jakub ; Maryška, Miloš (advisor) ; Církovský, Tomáš (referee)
The theme of this diploma thesis is the design and implementation of a dashboard for a specific paper company using the knowledge of an effective way of data visualization. The new dashboard is being developed as a replacement for the current reporting method, which does not allow the best information to be passed on. In order to design an effective dashboard, it was necessary to gain knowledge of specialized literature dealing with the topic of reporting, dashboarding and visualization of information. The following methods were used in the theoretical part: introduction and description of current situation in reporting and dashboards for obtaining a theoretical basis then finding principles and trends of data visualization for the design of effective graphic components displaying key information. In the practical part, it was necessary to analyze the current state of the reporting solution in the company and to identify requirements for the new dashboard. This information was obtained through semi-structured interviews with representatives of dashboard users. Introductory chapters are devoted to the interpretation of the theme dashboards. It introduces its historical development, basic concepts and it explains definition of dashboard. Subsequently, the author describes the characteristics of different kinds of dashboards. Another part deals with the theoretical basis of information visualization. Describes the basic processes of human perception and the ways it is affected by handling of the various attributes of the displayed information. The practical part of the thesis deals with the design and implementation of a dashboard in Mondi Štětí a.s. When designing the graphic design of the dashboard and the individual elements author uses the findings explained in the theoretical part. The dashboard prototype, created in Tableau, was subsequently consulted and validated with users. Based on their comments, it was modified and then implemented for real use. The result of this work is a dashboard of residence times, designed according to the principles of efficient data visualization. This dashboard meets user requirements and fulfills its defined purpose. Another benefit of the thesis is a summary of the theoretical knowledge and data visualization principles, which can serve as a source of instruction for the reader. At the end of the thesis, the author suggests ways to further develop the new dashboard.

Designing a controlling concept using the business intelligence system
Hejdánek, Michal ; Král, Bohumil (advisor) ; Houser, Václav (referee)
The Master Thesis deals with the use of the controlling concept in business management, Business Intelligence systems and their interconnection. The aim is to propose this integration link on the example of a particular company and at the same time to give management recommendations in areas that will be evaluated in the analysis as insufficient. The theoretical part of this thesis is divided into three main chapters. The first deals with the definition of controlling, its tools and organizations. The second one describes business intelligence, not just the basic principles of this technology, but also the choice of tools and the implementation process are explained. The following chapter lists two software tools that combine controlling and business intelligence in practice. The practical part is divided into a general description of the company, analysis of the applied elements of controlling and then the proposal of solution of insufficient areas and the process of BI implementation, which contains 12 steps which would enable to implement the BI concept.

Effective dashboard design in the analytical tasks of IS
Janeczková, Agata ; Šedivá, Zuzana (advisor) ; Pour, Jan (referee)
The thesis deals with analysing and designing an effective dashboard. By way of introduction the topics of Business Intelligence, data storages and data quality are described. Then, an overview of analytical outputs is given and the process of their formation is outlined. The basic principles of an effective design of management reports are described, with emphasis laid on the end user. The thesis focuses on important factors of efficiency, such as applicability of transferred information and the form of their transfer. The practical part concentrates on the improvement of the efficiency of a particular dashboard. Besides the rules of a correct design, knowledge of cognitive psychology is also used for this purpose. Upon an analysis of deficiencies of an existing dashboard, proposed changes are incorporated. Changes resulting in more effective transfer of information via a dashboard are based on a theoretical basis of the previous section.

Graphical Environment for Robot Simulation
Malina, Michal ; Kočí, Radek (referee) ; Zbořil, František (advisor)
This thesis deals with robot modelling and simulation of the robot behavior. At first we discuss a benefit of this kind of simulation. Next we describe the general scheme of robot. After that we select the environment where robot will be simulated in. There is a conception of this robot and explanation of the implementation in chosen environment. We continue with design and realization of the communication interface of this robot. The result of this procedure is robot with independent movement able to response to the obstructions and avoid them. Robot is able to create a map of the environment and use this map to find out the optimal way to the scheduled goal using the A* algorithm and achieve this goal. There is a possibility to use more robots in the scene. These communicate and the nearest one is able to get the goal.
