Controlled lighting and shading in smart house
Novák, Michael ; Morávek, Jan (referee) ; Bátora, Branislav (advisor)
This bachelor‘s thesis is focused on controlling lighting and shading in a smart house. Lighting control covers switching and dimming mechanisms. This thesis presents dimming options for different types of light sources. Following this is an overview of shading devices and system wiring, often called smart wiring. Specifically, the thesis focuses on the Foxtrot system from Teco a.s.. This work describes the sensors and actuators used for switching, dimming and shading control devices. New library of functional blocks for lighting and shading control for Foxtrot system was created, for they were not included in any standard library. All functional blocks that have use in the control of lighting or shading - including standard ones - are described in this work.

Evaluation of changes in pond dam monitored by EIS Method
Novák, Michael ; Maleňák,, Jaroslav (referee) ; Pařílková, Jana (advisor)
The bachelor's thesis deals with the evaluation of monitoring of earthen dike of fish pond which was built near the municipality Jevíčko. To identify the observed changes, which are related to variable loads earth dike with water, in time and space has been selected indirect electrical method of measuring electrical impedance spectrometry. This method is described in the work and the results of monitoring are published in graphical form and are commented.

Spatial analysis of snow cover using the method of electrical impedance spectrometry
Novák, Michael ; Zeleňáková, Martina (referee) ; Janál, Petr (referee) ; Pařílková, Jana (advisor)
Snow cover is an important climatic, hydrological and biological phenomenon. Especially in the empirical sciences, snow and snow cover monitoring has a long tradition, the importance of which has been reinforced in recent decades by the fact that snow cover (it is controlled by temperature and precipitation) is one of the important indicators of climate change. The dissertation thesis deals with the monitoring of snow cover in the years 2016 to 2019, mainly in the Czech Republic, in the Eagle Mountains. The characteristic properties of the snow cover and their changes, caused by changes in temperature, humidity and air flow rate or by the snow's own weight, are monitored by selected and available classical methods and non-traditional indirect method of electrical impedance spectrometry. The aim of the work was to master the measurement technique by a non-traditional method (design of measuring probes, delimitation of the space between the measuring electrodes, data collection and processing). The method is described in the work, the results of monitoring are published in graphical form and are commented. Another goal was to find a suitable mathematical description of the dependence between the measured electrical quantities and the properties of the snow cover, which can be used to determine the water value of snow and possibly also predict the avalanche danger. The technique of measurement by the indirect method of electrical impedance spectrometry was successfully mastered, including the definition of possible adverse effects affecting the measurement result. It was not possible to obtain a statistically significant set of data on the basis of which it was possible to determine the dependence between individual quantities. Classic manual methods can still be considered the standard for snow diagnostics and snow cover.
