Acoustic analysis of sentences complicated for articulation in patients with Parkinson's disease
Kiska, Tomáš ; Smékal, Zdeněk (referee) ; Mekyska, Jiří (advisor)
This work deals with a design of hypokinetic dysarthria analysis system. Hypokinetic dysarthria is a speech motor dysfunction that is present in approx. 90 % of patients with Parkinson’s disease. Next there is described Parkinson's disease and change of the speech signal by this disability. The following describes the symptoms, which are used for the diagnosis of Parkinson's disease (FCR, VSA, VAI, etc.). The work is mainly focused on parameterization techniques that can be used to diagnose or monitor this disease as well as estimate its progress. A protocol of dysarthric speech acquisition is described in this work too. In combination with acoustic analysis it can be used to estimate a grade of hypokinetic dysarthria in fields of faciokinesis, phonorespiration and phonetics (correlation with 3F test). Regarding the parameterization, new features based on method RASTA. The analysis is based on parametrization sentences complicated for articulation. Experimental dataset consists of 101 PD patients with different disease progress and 53 healthy controls. For classification with feature selection have selected method mRMR.

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.

Present State of Vibration-diagnostics
Hamplová, Veronika ; Vdoleček, František (referee) ; Zuth, Daniel (advisor)
This bachelor’s thesis is interested in new trends in vibrodiagnosis. There are described and compared properties of present-day measuring instruments and sensors. The thesis shows the newest trends and progress in the wireless transmission, minimisation and better accuracy of sensors. Then, there are described portable instruments, where progress has been registered in two fields, minimisation and better accuracy.

Methods of Technical Prognostics Applicable to Embedded Systems
Krupa, Miroslav ; Ďaďo, Stanislav (referee) ; Tůma, Jiří (referee) ; Bejček, Ludvík (advisor)
Hlavní cílem dizertace je poskytnutí uceleného pohledu na problematiku technické prognostiky, která nachází uplatnění v tzv. prediktivní údržbě založené na trvalém monitorování zařízení a odhadu úrovně degradace systému či jeho zbývající životnosti a to zejména v oblasti komplexních zařízení a strojů. V současnosti je technická diagnostika poměrně dobře zmapovaná a reálně nasazená na rozdíl od technické prognostiky, která je stále rozvíjejícím se oborem, který ovšem postrádá větší množství reálných aplikaci a navíc ne všechny metody jsou dostatečně přesné a aplikovatelné pro embedded systémy. Dizertační práce přináší přehled základních metod použitelných pro účely predikce zbývající užitné životnosti, jsou zde popsány metriky pomocí, kterých je možné jednotlivé přístupy porovnávat ať už z pohledu přesnosti, ale také i z pohledu výpočetní náročnosti. Jedno z dizertačních jader tvoří doporučení a postup pro výběr vhodné prognostické metody s ohledem na prognostická kritéria. Dalším dizertačním jádrem je představení tzv. částicového filtrovaní (particle filtering) vhodné pro model-based prognostiku s ověřením jejich implementace a porovnáním. Hlavní dizertační jádro reprezentuje případovou studii pro velmi aktuální téma prognostiky Li-Ion baterii s ohledem na trvalé monitorování. Případová studie demonstruje proces prognostiky založené na modelu a srovnává možné přístupy jednak pro odhad doby před vybitím baterie, ale také sleduje možné vlivy na degradaci baterie. Součástí práce je základní ověření modelu Li-Ion baterie a návrh prognostického procesu.

Diagnostics and Maintenance Design
Schindler, Marek ; Pohanka, Martin (referee) ; Kudrna, Jan (advisor)
Failures of the roads are an integral part of the use and aging infrastructure. Before proposing their maintenance and repair is necessary to make the diagnosis of the road. Technical specifications of TP 82 and TP 87 describe the correct execution of diagnostic methods, their methods of evaluation and suggested repair of pavements. In the Bachelor's work I am making the diagnosis of asphalt, with the subsequent proposal for repairs on the road III/4301 in the village of Nechvalín. All measurements, evaluation, design, repair and photo documentation is included in this work.

Evaluation of the structural static condition of the existing structure
Svoboda, Štěpán ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This thesis focuses on the assessment of the structural-statical condition of a building affected by a fire. The purpose of the evaluation is to determine the extent of damage and explore possibilities for future use. The theoretical part introduces the issue of fires in various structures and examines the impact of fire on different types of materials and constructions. In the practical part, there is an own evaluation of the object, a static assessment, the results of the inspection and a summary of the conclusions from the evaluation.

Construction of synthetic skin type sensors
Ropog, József ; Vdoleček, František (referee) ; Zuth, Daniel (advisor)
This master’s thesis deals with the diagnosis of thermal environment using synthetic skin type sensors. The synthetic skin type sensor is a compact sensor ideal for simulating human skin. The aim is to design and implement such a sensor and test its properties. On the market there are no compact sensors with that kind of abilities and our goal is to design the cheapest, but still viable sensor. Measurement and data processing is implemented using measurement cards and LabVIEW software. The work also contains a design of signal conditioning without the use of measurement cards.

Pseudo-colour imaging of the monochromatic pictures
Boleček, Libor ; Drastich, Aleš (referee) ; Říčný, Václav (advisor)
Diploma thesis displaying black and white image in false color includes a study of methods and creation of computer software. The main function of the program is to convert the monochrome image into the pseudo colors. This procedure is achieved increasing the diagnostic yield of image. The program may find application in medical field. The pseudocoloring is used several different methods for obtaining the best results, combined with modifications increasing brightness scale image contrast images. The program is created in the programming environment of Visual Studio 2008 and written in C # programming language. Entry program is monochrome images in various formats (JPEG, BMP). The output of the program can be printed in a false-color image or stored image again in several different formats.
