Datový formát pro elektrofyziologické experimenty
Vaněk, Jiří
2015 - English
V současné době neexistuje standard datového formátu pro ukládání elektrofyziologických dat. Tento standard je nutný pro rozšíření možností sdílení dat s dalšími výzkumníky. Tato diplomová práce se zabývá úpravou modelu pro reprezentaci ukládání dat z elektroencefalografických a experimentů využívajících metodu evokovaných potenciálů a metadat těchto experimentů. Byly prozkoumány existující datové formáty pro ukládání naměřených binárních dat a metadat a jejich ontologie, byla definována terminologie, struktura a byl vybrán vhodný formát pro ukládání těchto dat. Dále byl vytvořen program, který umožňuje ukládat do vybraného formátu naměřená data a informace o experimentu. Currently there is no standardized data format for storing electrophysiological data. This standard is necessary for the improvement of sharing capability. This master thesis deals with the adjustments of data and metadata model for measured data from Electroencephalography and Event-related potentials experiments. The formats for storing electroencephalography data and their ontology were examined. The adjusted file format for export of measured binary data and metadata with experiment details was chosen. Terminology and structure for the experimental metadata were defined. The program that exports the measured data and information about the experiment into the appropriate file format was also implemented.

An approach to the machining of hard coatings prepared by laser cladding and thermal spraying
Carou, Diego; Řehoř, Jan; Vilček, Igor; Houdková-Šimůnková, Šárka
2015 - English
Thermal spraying and laser cladding are widely used in industry for different coating applications. The use of these techniques usually requires a finishing post-process. However, the characteristics of these coatings, such as their high hardness, make difficult to achieve satisfactory results with conventional machining processes. The present study provides a description of the main characteristics of the laser cladding and thermal spraying processes. For machining of these coatings, conventionally, grinding is the first option selected. However, modern industries require gaining flexibility and improving their productivity. Thus, other alternatives such as milling or turning need to be assessed. In this sense, in the last section, several experimental investigations on the machining of WC-Co and Stellite coatings are presented. These studies can bring some insights to face the machining of hard coatings prepared by the laser cladding and thermal spraying techniques. For instance, they can help in the selection of the cutting parameters and provide interesting results on the use of different tool materials and tool geometries.

Design and development of measurement JIG system
Němec, Jiří
2015 - English
Following article describe design and production of the universal clamping jig for clamping measured parts in to three axis measuring machine. This clamping jig was designed and produced under exchange program Erasmus. Department Manufacturing Engineering Group (GEF) University of Vigo (Spain) and Department of Machining Technology (KTO) University of West Bohemia (Czech Republic) cooperated at this project. The clamping jig was created for extension possibilities of fixing of the measured parts in to work space of the meas-uring machine. Current state was insufficient. The worker of the department GEF specified requirements to the new clamping jig. The finally design of the clamping jig had to be universal and had to allow measuring parts in large series.
Individual concepts were designed based on the specification and consultations with the project initiator. The optimal design was chosen from these concepts. The concepts are described in this article. Machines and tools, which are used for fabricating part of the jig, are described in the article. Results of the project are summa-rized in the conclusion.

Possibilities of potentiometric methods of detection of cracks in forging tools at their renovation
Pilc, Jozef; Sajgalik, Michal; Struharnansky, Jozef; Rakoci, Jozef; Varga, Daniel
2015 - English
Industrial production, which uses the forging tools constantly increases the requirements for the consumption of forging tools and the need for fast and flexible renovations of them. Forging tools made from special tool steels are highly cost-intensive. The main cost component is the price of the material, heat treatment and other chemi-cal-heat treatment surfaces. This is the main reason why it is necessary to think about renovation at the design stage, in case of the need for repairs. Main weaknesses of the renovations is the insufficient ability of identifica-tion of the cracks spreading from the surface towards the core of the basic components. An important factor in the renovation process is the optimal choice of technology to restore the mechanical and physical properties of tools at an acceptable price, of course. The main issue in the choice of the optimal technology is heat treatment to achieve a high hardness and surface of the die, which is nitrided to ensure wear resistance. This article deals with the application of non-destructive potentiometric detection technology when considering the size of die forging cracks that arise in the process of forming.

Reaktivní vysokovýkonová pulzní magnetronová depozice vrstev oxidů vanadu
Vytisk, Tomáš
2015 - English
Tato práce je zaměřena na vysokovýkonovou pulzní magnetronovou depozici tenkých vrstev oxidu vanadu. Cílem je vytvořit termochromickou vrstvu oxidu vanadu, jejíž přechodová teplota bude nižší než 68 °C a bude vykazovat změny propustnosti v oblasti infračerveného záření. Vrstvy byly připravovány v plynné směsi argonu a kyslíku za konstantního tlaku pracovního plynu par = 1.0 Pa. Vanadiový terč (99.999 %)byl zatěžován průměrnou výkonovou hustotou při depozici = 12.4 14.0 W/cm2. Délka trvání pulzu byla t1 = 40, 50 a 80 s s opakovací frekvencí napájecího zdroje f = 250, 200 a 125 Hz, dle uvedeného pořadí. Pomocí elipsometrie byla zjištěna tloušťka deponovaných vrstev a zkoumány optické parametry jako index lomu n a extinkční koeficient k. V této práci jsou prezentovány výsledky vlivu depozičních parametrů, zejména délky trvání pulzu t1, teploty substrátu T a délky depozičního procesu t (tloušťky vrstvy) na termochromické vlastnosti připravených vrstev. The aim of this thesis is to fabricate thermochromic thin film of vanadium oxide. High power impulse magnetron sputtering is used to prepare a thermochromic film with structure changes below transition temperature Tc = 68 °C providing variable transmittance in infrared spectrum. The films were prepared in oxygen and argon gas mixture, at pressure of working gas (Ar) par = 1.0 Pa. A vanadium target (99.999 %) was loaded by average power density during deposition = 12.4 14.0 W/cm2. Other deposition parameters were: voltage pulse length t1 = 40, 50 and 80 s with power supply repetition frequency f = 250, 200 a 125 Hz, respectively. Ellipsometry was used to measure optical characteristics () and parameters like refraction index n and extinction coefficient k. This work presents an influence of deposition parameters (voltage pulse length t1, substrate temperature T and deposition time t) on thermochromic behaviour of the thin films.
