Product Data Visualization in PNC Build System
Korytár, Patrik ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
Cieľom tejto bakalárskej práce je zlepšiť vizualizáciu dát súvisiacich s produktami build systému PNC na jeho novom webovom používateľskom rozhraní. Hlavné vizualizačné prvky zahŕňajú tabuľky, grafy, sieťové grafy a palubné panely. Táto práca analyzuje vstupy od používateľov build systému PNC, aby sa zohľadnili skutočné potreby používateľov. Na základe analýzy bol vytvorený dizajn pre úplne nové komponenty používateľského rozhrania a niektoré z už existujúcich boli prepracované. Na ilustráciu nového dizajnu sa vytvorili nákresy. Navrhnuté boli nové koncové body REST API pre dáta vyžadované novými komponentami. Nové funkcie boli následne implementované. Implementačný jazyk je TypeScript. Hlavné knižnice zahŕňajú React, Chart.js, Sigma.js a Graphology. Ako výsledok má teraz nové používateľské rozhranie systému PNC nové funkcie, ktoré pomáhajú s používaním stránok súvisiacich s produktami. Implementácia je tiež ľahko rozšíriteľná pre viac vizualizácií tohto druhu.

Electroencephalography
Jarošová, Veronika ; Ronzhina, Marina (referee) ; Chmelař, Milan (advisor)
This semestral paper has its aim to describe the electroencephalography. The beginning of paper is devoted to the history of electroencephalography, then there is both spontaneous and evoked brain activity described. Further, the paper deal with the electroencephalography. At the conclusion of teoretical part is described the methodology and processing of electroencephalography signal. The practical part of the work is focused on the creation of three various exercises on the epilepsy theme, reflexes and memory. Then the exercises were verified practically at fourteen volunteers. Further, in the work there is mentioned the instruction for particular measures, valuation results and its discussion.

Biofeedback and its practical use
Dvořák, Jiří ; Hrozek, Jan (referee) ; Čmiel, Vratislav (advisor)
The aim of this work is describe common methods of biological feedback therapy that is used to treat some psychosomatic diseases. Subsequently, the description is focused on minimal brain dysfunction treatment by the help of EEG biofeedback. Properties and technical requirements for this therapy are concretized. The last part of this thesis is dedicated to the design and realization of practical software tool for EEG biofeedback therapy which is made in LabView 7.1. The M535 acquisition unit and NI USB-6221 measuring device are used for hardware solution.

ECG quality estimation
Pospíšil, Jan ; Smíšek, Radovan (referee) ; Smital, Lukáš (advisor)
This bachelor thesis deals with the question of estimation of the quality of the ECG signals, which is a key parameter for determining the diagnosis. The theoretical part deals with the basic knowledge concerning cardiac physiology, electrocardiography and finally the types of interferences that can occur during the measurement. The following practical part will deal with the published methods and the proposal of methods for estimating signal quality and their testing on artificial and real data.

Detection of Landscape in Images
Dufka, Zbyněk ; Křupka, Aleš (referee) ; Číka, Petr (advisor)
The target of this thesis is theoretical summary of methods, which are used for detection of objects in database of images. Next step is to develope own algorhytm for detection of landscape. Theoretical part describes methods Viola-Jones and HOG, which are used for detection of human faces and anomalies on radiographs. This analysis is concerned with segmentation method and algorhytm for data mining from images, which contain the landscape scenery. Appropriate method and its analysis could contribute to create and to implement into developement enviroment RapidMiner in the second part of thesis.

Automated Detection of graphic elements in EEG signal
Jančová, Ivana ; Ronzhina, Marina (referee) ; Bubník, Karel (advisor)
This thesis deals with the analysis of EEG, namely detection of graphic elements. The aim of the thesis is to describe methods suitable for detection of graphic elements and implementation of the two methods in MATLAB. The first part of the thesis describes the basics rhythms, artifacts and epileptiform transients occurring in the EEG. The second part deals with the methods of detection and their mutual comparison. The discussed methods are spectral analysis, correlation analysis, wavelet transform, cluster analysis and matched filter. Other parts of the thesis describe the database PhysioBank and implementation of the correlation analysis and matched filter. In the last part is the comparison of the success of selected methods and comparison is done by calculating sensitivity and positive predictive value.

HDR Image Artifact Compensation
Müllerová, Věra ; Zemčík, Pavel (referee) ; Musil, Martin (advisor)
Tato diplomová práce se zabývá syntézou HDR obrazu (High Dynamic Range Imaging). HDRI technologie se stala v posledních letech velice populární. Běžný a nejvíce používaný způsob vytvoření HDR obrazu je spojení více snímků stejné scény pořízených pomocí různých expozičních časů. Tato technika funguje správně pouze v případě, že se jedná o statickou scénu. Pokud je však ve scéně nějaký pohyb ve chvíli, kdy se pořizují snímky dané scény, výsledný HDR obraz obsahuje artefakty zvané jako duchy. V této práci jsou prezentovány základní informace o HDRI se zaměřením na metody odstraňující artefakty z HDR obrazů. Práce shrnuje již existující metody a dvě z nich - tzv. bitmap movement detection a histogram based ghost detection - představuje jako vhodné pro použití v real-time skládání HDR obrazu a pro implementaci na FPGA (Field-Programmable Gate Array) architektuře. Tyto metody jsou v práci implementovány v programovacím jazyce C++ jako prototypy. Navíc je zde navržena modifikace metody založené na výpočtu histogramu pro jednodušší a efektivnější implementaci na FPGA architektuře.

Build Parallelization in Jenkins Environmnent
Lukášová, Michaela ; Zachariášová, Marcela (referee) ; Dolíhal, Luděk (advisor)
The goal of this bachelor's thesis is parallelization of building Codasip Studio, highly automated developement environment. It focuses on parallelization in Jenkins environment. The implemented solution is mainly focused on speeding up the actual build process. The solution uses a number of Jenkins plugins and several shell scripts, which ensures start of compilation, installation or creation of the final package.

Visualization of 3D data in biomedical applications
Karzel, Michal ; Harabiš, Vratislav (referee) ; Štohanzlová, Petra (advisor)
This thesis describes the basic principle of optical coherence tomography and prepro- cessing of the measured raw data. Preprocessing is focused mainly on noise filtration, removing artifacts, normalization, conversion and compression of raw data. In this way preprocessed data is saved in a *. PFRG file as ”preprocessed fringe data”. Those pre- processed data will be visualised by simply software, which support three methods of visualisation. Volume data represented by voxels. Reconstruction of volume by marching cube algorithm. Cuts through volume along X, Y and Z axis.
