Design of Power HIL unit for Li-pol cell simulation
Pribulla, Daniel ; Sova, Václav (referee) ; Chalupa, Jan (advisor)
This thesis deals with design and construction of a Li-po cell Power-HIL simulator intended for testing of a small wireless module's powering. The simulator is based on a battery model which includes the influence of temperature and battery degradation on battery parameters. To estimate model parameters a series of tests on real Li-po cell with capacity 250mAh were performed. Charging and discharging tests were performed by different temperatures of the battery. In purpose of this test a simple thermal chamber was constructed. Design of the power electronics of the device was tested in the Simscape library of the Matlab Simulink. The result is a working prototype of the simulator tested for charging and discharging of batteries with capacity in range 100-1500 mAh. The simulator can be controlled with graphical user interface capable of setting the battery parameters and real time observation of the model variables.

Semi-automatic computerized system for the segmentation of online handwriting
Gavenčiak, Michal ; Mekyska, Jiří (referee) ; Zvončák, Vojtěch (advisor)
The prevalence of developmental dysgraphia among school children is between 10-30%, yet in Czech Republic, there is no objective method to diagnose it or determine its severity. Past studies have shown the possibility of automatic diagnosis using digital data gathered using a digitizing tablet and a stylus. Data gathered within an ongoing study contain information on position, time stamp, tilt, pressure and azimuth of the stylus. These data are, however, unsuitable for further analysis due unspecified number of exercises contained in one SVC file. Within this thesis the data is analysed and a program, which is able to segment these data into units of exercises and display the processed data on the screen, is designed and implemented.

Creation of GUI for optimization of electrical machines
Bártková, Tereza ; Klíma, Petr (referee) ; Knebl, Ladislav (advisor)
This work follows the development process of graphical user interface (GUI) spanning from choosing the right tools for implementation to the implementation itself. The purpose of the work was making the optimization program user-friendly by creating a communication layer between the optimization algorithm and the user and demonstrating its functions. First of all, the study of various programming languages and their toolkits regarding GUI programming was undertaken. Python was chosen because the original program is written in it, also software development in Python is probably the quickest one. Furthermore there are analyzed characteristics of this language and PyQt, which is a tool meant for GUI creation. The third chapter introduces very thoroughly the issues of electrical machines and their optimization. Introduction of these issues is followed by brief description of two optimization methods being used in electrical machines optimization. Following chapter introduces the actual machine under the optimization study, on which the final program was tested. Afterwards follows detailed description of application layout created in Qt Designer. New program structure enriched with graphical user interface is described and its functions are shown. Finally there is a guideline on how to use this program and the optimization is executed accordingly. Also, the results of the optimization are analyzed.

Dictation System - User Interface
Svoboda, Martin ; Fapšo, Michal (referee) ; Schwarz, Petr (advisor)
The term dictation system we understand the software system, which consists of two main parts. The first part is recognizer spoken word, the second is the user interface for user interaction and processing output recognizer. This work focuses on the user interface dictation system, a description of comunication between the recognizer and the user interface, the correction of words coming from the recognizer and transfer numbers from verbal to numerical form.

Principles of Creation and Set of Demo Applications Running over AndroidOS
Sztefek, Lukáš ; Bidlo, Michal (referee) ; Strnadel, Josef (advisor)
The aim of this thesis is to describe the basic principles of creating applications for Android operating system. The reader gradually gets familiar with the basic building elements of applications, including the creation of a graphical user interface. A great emphasis is placed on the description of sensors interface, which precedes chapter describing implementation of several applications. These applications use sensors for their activity. This thesis gives a basic understanding of developing applications for Android OS.

Balloon Pilot's Assistent
Hora, Tomáš ; Szőke, Igor (referee) ; Herout, Adam (advisor)
This thesis describes concept and implementation of application assisting balloon pilots with guiding to a chosen target. Theoretical part is focused on basics of ballooning and navigation. Designed application uses proprietary OziExplorer files, clearly displays all information from external GPS unit connected via COM port and saves travelled path and waypoints. Important feature of the application is getting forecast of wind flow in various altitudes from the internet before the flight and analysis of information from GPS for calculation actual air flow during flight. In the end of this thesis the application is tested in real environment and its functionality is evaluated.

Graphical User Interface for Packet Generator
Chromčák, Michal ; Kováčik, Michal (referee) ; Matoušek, Jiří (advisor)
According to increasing requirements on speed of different software and hardware components, there are solutions, which can, by principle, reach better parameters, then solutions commonly known. One of them is to use software with hardware acceleration on the field of generating synthetic network traffic. Exactly this way a packet generator was implemented, in current version without graphical user interface. But to let this system spread into the target group of users, there is need to implement also this interface. This bachelor's thesis describes proposal of graphical interface, its implementation in JavaFX programming language, testing on real users and tutorial demonstrating how to use this interface.

Electronic Tool for Managing Innovative Study Materials
Hlipala, Ľuboš ; Szőke, Igor (referee) ; Herout, Adam (advisor)
The aim of this diploma thesis is to create a mobile application that provides the users with structured, well-arranged and at the same time effective platform to share, present and practice the knowledge of various kinds. The work analyzes several existing applications and systems for education and sharing information and describes different approaches of mobile app development with the focus on multiplatformity. The main part of the work describes the gradual development of the application and documents the created format for the presentation and sharing of study materials, with the possibility of practical practice of the acquired knowledge.
