Electronic Circuits Simulations and Parasitic Inductances
Ševčík, Roman ; Šátek, Václav (referee) ; Kunovský, Jiří (advisor)
This work deals with the solution of differential equations and systems of differential equations through the use of parasitic inductances. Thus obtained equations serve as input data for the simulation tool TKSL, which allows their solutions using the Taylor series. Furthermore, according to the proposal in C# is implemented a system for graphic display output data from TKSL. The system makes it possible to view trending as a continuous two-dimensional graphs.

Helping tool for AVR microcontrollers programming in C language
Ševčík, Radek ; Dřínovský, Jiří (referee) ; Frýza, Tomáš (advisor)
This article describes AVR Wizard programme that was developed for AVR Studio. This software simpliefies microcontrollers (MCUs) programming in a way of general peripheries settings and registers settings for varied MCUs. AVR Wizard is able to generate C language-based MCU main programme structure with chosen settings. User-friendly handling and no longer detailed studies of MCU datasheets are also main advantage.

Certified methodology for textile deposition
KUŽELOVÁ, Zdenka ; ŠEVČÍK, Richard ; PŘÍHODA, Jiří ; NASADIL, Petr
The methodology was created for the neeeds of museum workers handling and depositing textile artefacts. The methodology is focused on depositories where textile artefacts are stored. The content is focused on traditional folk clothing from Moravia originating from the period of 1850-1950 and the methodology is specific in this way. It is necessary to emphasize that the folk textile (clothing) was stored in its own way which has to be kept and which some attention should be paid to.

Analysis of soils
Šašek, Petr ; Viani, Alberto ; Ševčík, Radek ; Mácová, Petra ; Machová, Dita
High concentrations of solid particles in the air may cause health problems. Sources of such particles can be natural processes, as well as human activity (e.g. coal mining, etc). Another source of contamination is the so-called secondary dustiness, which arises from vortex of already settled solids and dispersion into the atmosphere. Secondary dustiness formation is mainly affected by the surface moisture. The increase of humidity leads to agglomeration of the particles, resulting to their falling on ground, thus inhibiting their distribution in the atmosphere. The aim of the study was to analyse the soil dust particles collected on the filters of impactor, with respect to particle size and composition.

Qualitative and quantitative analysis of clay soils
Šašek, Petr ; Viani, Alberto ; Ševčík, Radek ; Fabeš, Roman ; Řehoř, M.
Clay minerals are a group of aluminum silicates with a layered structure, which is formed by tetrahedrally and octahedrally arranged molecules with cations of potassium, magnesium, sodium and others. By combining layers of octahedra and tetrahedra several types of layered structures may be produced, which can form various types of clay minerals in nature. Clay minerals are divided into three main groups: kaolinite, smectite and illite. The aim of the study was to qualitatively and quantitatively analyse the clay minerals in soil samples; the main objective was to determine the phase transition on the boundary of smectite and illite phases. For this purpose XRD analysis with Rietveld refinement was employed.

The determination of material characteristics of natural and artificial stone samples from Marian Column at Hradčany Square in Prague
Slížková, Zuzana ; Zeman, Antonín ; Petráňová, Veronika ; Viani, Alberto ; Pérez-Estébanez, Marta ; Frankeová, Dita ; Ševčík, Radek ; Mácová, Petra ; Janotová, Dana ; Hasníková, Hana ; Niedoba, Krzysztof ; Hauková, Petra
Within the survey before restoration intervention material properties of natural and artificial stones that are part of the Marian Column at Hradcany Square in Prague were determined. 15 samples were subjected to extensive instrumental analysis, whose output is not only chemical and mineralogical composition of the samples, but also the degree of degradation including a description of the porous system and the level of salinity.
