Development of laboratory exercises for subject the Signals and systems analysis
Doleček, Josef ; Mucha, Ján (referee) ; Zvončák, Vojtěch (advisor)
The bachelor thesis deals with basic operation with signals and, using demonstrative applications in Matlab, it should explain these operation to CASS (Signals and Systems Analysis) students. In the theory part continuous-time signals (signals classification, periodic signals, Fourier series), complex numbers, sampling and discrete-time signals (operation of convolution and correlation) are described. Practical applications explain: square signal harmonics synthesis, two discrete-time signals convolution and cross-correlation, object distance detection by radar using cross-correlation, complex model of harmonic signal and signals sampling.

Acoustic call analysis application for Android system
Hejda, Jakub ; Mucha, Ján (referee) ; Mekyska, Jiří (advisor)
The telemedicine’s capabilities are rapidly expanding due to technological advances in a smarphone development. The goal of this thesis was to suggest the architecture and prepare the design providing acquisition, processing and synchronization of voice para- meters recorded by patients with Parkinson’s disease and to implement such system. The architecture was completed successfully, it consists of the mobile application able to record patient’s calls, the server application introducing an interface to store and synchronize the data and to provide them to the web application, where doctors can see the data and analyze it. Implementation of the server application was finished according to the design and to the requirements for robustness and security as well as the web application. By an extension of the existing mobile application for recording voice calls there was developed a huge system for the analysis of this disease.

Mobile application for dysarthria assessment utilising the Test 3F
Grenčík, Dominik ; Mucha, Ján (referee) ; Mekyska, Jiří (advisor)
Speech dysarthria is a impaired communication ability, a motor disorder affecting basic modal aspects of speech. In the Czech Republic, Test 3F, developed in the current clinical speech therapy, is used in diagnostics in both text and electronic form, consisting of 45 execution tasks. Currently, the trend of using mobile applications is expanding in various areas of life, which speed up and streamline human communication and work. The aim of this work is to create a simple but high-quality and reliable mobile application of Test 3F as a diagnostic tool for the examination of speech dysarthria in an effort to help clinical speech therapy in simplifying the diagnosis of this disorder. Mobile application is programmed using several programming languages: Backend is programmed in PHP using the Laravel framework. Frontend is programmed in JavaScript using the React library and the Material UI component library.

Assessing Economic Situation of a Company and Proposals for Its Improvement
Mucha, Jakub ; Ponížilová, Veronika (referee) ; Doubravský, Karel (advisor)
This diploma thesis deals with the evaluation of the economic situation Šálek s.r.o. in the years 2013 to 2020. The theoretical part describes the financial indicators, time series, regression and correlation analysis. The analytical part contains calculations of financial indicators, some of which are subjected to static analysis, which is designed to determine the expected development of indicators in the next two years or to show the dependence between selected indicators. The last part of the thesis deals with proposals to improve the current economic situation of the company.

Library for Python used for dysarthric speech parameterization
Koutný, Tomáš ; Galáž, Zoltán (referee) ; Mucha, Ján (advisor)
Bachelor thesis is focused on parameterization of dysartoric speech. Attention is paid to methods of Speech Signal Analysis for Parkinson's disease, modern parametrization techniques, which are designed to quantify the damage of motoric aspects of speech and implementation of selected parameters in Python. The main goal of this work was to create a parameter library that is realized in the PyCharm development environment.

Advanced Parameterisation of Online Handwriting in Writers with Graphomotor Disabilities
Mucha, Ján ; Šimák, Boris (referee) ; Drotár,, Peter (referee) ; Mekyska, Jiří (advisor)
Grafomotorické obtíže (GD) výrazně ovlivňují kvalitu života školním věkem počínajíc, kde se vyvíjejí grafomotorické schopnosti, až do důchodového věku. Včasná diagnóza těchto obtíží a terapeutický zásah mají velký význam k jejich zlepšení. Vzhledem k tomu, že GD souvisí z vícerými symptomy v oblasti kinematiky, základní kinematické parametry jako rychlost, zrychlení a švih prokázaly efektivní kvantizaci těchto symptomů. Objektivní výpočetní systém podpory rozhodování pro identifikaci a vyšetření GD však není dostupný. A proto je hlavním cílem mé disertační práce výzkum pokročilé metody parametrizace online písma pro analýzu GD se speciálním zaměřením na využití metod zlomkového kalkulu. Tato práce je první, která experimentuje s využitím derivací neceločíselného řádu (FD) pro analýzu GD pomocí online písma získaného od pacientů s Parkinsonovou nemocí a u dětí školního věku. Byla navržena a evaluována nová metoda parametrizace online písma založena na FD využitím Grünwald-Letnikova přístupu. Bylo dokázáno, že navržená metoda významně zlepšuje diskriminační sílu a deskriptivní schopnosti v oblasti Parkinsonické dysgrafie. Stejně tak metoda pozitivně ovlivnila i nejmodernější techniky v oblasti analýzy GD u dětí školního věku. Vyvinutá parametrizace byla optimalizována s ohledem na výpočetní náročnost (až o 80 %) a také na vyladění řádu FD. Ke konci práce byly porovnány víceré přístupy výpočtu FD, jmenovitě Riemann-Liouvillův, Caputův společně z Grünwald-Letnikovým přístupem za účelem identifikace těch nejvhodnějších pro jednotlivé oblasti analýzy GD.

Music mood and emotion recognition using Music information retrieval techniques
Smělý, Pavel ; Mucha, Ján (referee) ; Kiska, Tomáš (advisor)
This work focuses on scientific area called Music Information Retrieval, more precisely it’s subdivision focusing on the recognition of emotions in music called Music Emotion Recognition. The beginning of the work deals with general overview and definition of MER, categorization of individual methods and offers a comprehensive view of this discipline. The thesis also concentrates on the selection and description of suitable parameters for the recognition of emotions, using tools openSMILE and MIRtoolbox. A freely available DEAM database was used to obtain the set of music recordings and their subjective emotional annotations. The practical part deals with the design of a static dimensional regression evaluation system for numerical prediction of musical emotions in music recordings, more precisely their position in the AV emotional space. The thesis publishes and comments on the results obtained by individual analysis of the significance of individual parameters and for the overall analysis of the prediction of the proposed model.
