Data Analysis and Clasification from the Brain Activity Detector
Jileček, Jan ; Černocký, Jan (referee) ; Szőke, Igor (advisor)
This thesis aims to implement methods for recording EEG data obtained with the neural activity sensor OpenBCI Ultracortex IV headset. It also describes neurofeedback, methods of obtaining data from the motor cortex for further analysis and takes a look at the machine learning algorithms best suited for the presented problem. Multiple training and testing datasets are created, as well as a tool for recording the brain activity of a headset-wearing test subject, which is being visually presented with cognitive challenges on the screen in front of him. A neurofeedback demo app has been developed, presented and later used for calibration of new test subjects. Next part is data analysis, which aims to discriminate the left and right hand movement intention signatures in the brain motor cortex. Multiple classification methods are used and their utility reviewed.
Design of a mobile robot with an augmented reality user interface
Adámek, Roman ; Věchet, Stanislav (referee) ; Bastl, Michal (advisor)
This thesis deals with the design and construction of a four-wheeled mobile robot designed for an interactive exhibit and educational purposes. This robot is capable of wireless image transmission and manipulation with objects. In addition, this thesis deals with the construction of a charging station and user interface for controlling the robot which contains elements of augmented reality and minigames.
RaspberryPI camera checker
Bubeník, Martin ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
The diploma thesis deals with the industrial inspection of correctly made connectors based on computer recognition, and the detection and recognition application is implemented in Python on the Raspberry Pi platform.The work uses empirically known OpenCV library for recognition. The work also deals with the selection of suitable hardware devices, which are a camera with a lens and an illuminator, from which is created one compact device together with the Raspberry Pi microcomputer. The compact device is further mounted on the designed mechanical structure under which is created inspection zone. Finally, Raspberry Pi has a web-based user interface to check the inspection and the interface to write the data to the database.
Tool for parsing and analysing of web pages
Odstrčil, Štěpán ; Ilgner, Petr (referee) ; Galáž, Zoltán (advisor)
This bachelor’s thesis is dealing with parsing of text in HTML pages and its analysis. Practices from Natural Language Processing were used. There were written libraries (or packages) in programming language Python, with use of modern practices, techniques and libraries. The usages and examples of these libraries and classes were made. All these libraries were tested using Unit tests. Application contains GUI (Graphical User Interface) for wasier usefulness and demonstration of functionality.
Electronic notice board LCD
Bureš, Michal ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
This diploma thesis deals with the research of existing solutions of electronic information systems. The purpose of this survey is to inspire what is offered to users of these professional systems, or what users expect from these systems. Based on the acquired knowledge, the thesis also deals with the design of its own system, which can serve as another alternative to professional solutions of companies on the market, in the sense of the concept of solution of the given task. After the design of the system, the thesis deals chronologically with the selected "tools" used for the actual implementation of the assigned task Electronic Information Boards. Both hardware and software parts of the task, which form the majority of this thesis. At the end of the work are presented practical results.
STEMLab based data acquisition system
Pavlík, Radim ; Kováč, Michal (referee) ; Kubíček, Michal (advisor)
Thesis deals with design of acquisition system, working on developing platform STEMLab (Red Pitaya). Goal is possibility of monitoring analog signals with adjustable sampling frequency and length of acquisition. Software was created for both controlling part (Python application) and for platform itself (embedded C, Python) using the appropriate FPGA-HW design (HDL). Thesis describe how to work with platform ecosystem, control and behaviour of aplications created during the proces of getting acquainted with the platform and options how aplications could be created.
Detection of similarity in program codes
Maťašová, Kristýna ; Vítek, Martin (referee) ; Kašpar, Jakub (advisor)
The Bachelor introduces the concept of plagiarism and possible kinds of plagiarism. It focuses on the problem of detecting the similarity of source codes, especially with graphical interfaces in the MATLAB environment. It also describes already existing detectors. The practical part of thesis is focused on finding appropriate flags for detection of similarity in source codes and introduces the metric of detected flags. It also describes the internal logic of created detector of similarity and discusses the results of its testing.
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.
Graphical Viewer and Simple Editor of ELF File
Omacht, Martin ; Martiško, Jakub (referee) ; Křivka, Zbyněk (advisor)
The goal of this thesis is to create an application with graphical user interface that provides graphical overview of internal structure for binary files in ELF format while also allowing simple editing. The application handles corrupted files and supports Windows and Linux operating systems. It is implemented in C++ with graphical interface created using Qt library. To picture the internal structure of the given ELF file, a custom diagram was designed and implemented.
Optimization of G-Quadruplex Identification Algorithm
Labudová, Dominika ; Martínek, Tomáš (referee) ; Hon, Jiří (advisor)
Identification of G-quadruplexes in DNA has been the interest of many studies  in recent years. As a result, many identification tools were created. This bachelor's thesis focuses on analysis and optimization of a tool called pqsfinder along with creating a web interface for this tool. The optimization provided significant increase in the algorithm's speed and ability to process long DNA sequences. The web interface was designed and implemented using modern and effective technologies with emphasis on the user friendliness of the web application.
