Design of suitable HW and SW components for remote data transmission
Pietrowicz, Daniel ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
This thesis is focused on the design of remote data transmission equipment, without access to mains power. The device will measure the voltage of the gas pipeline and send this information to the operator for processing. Analysis of today's technologies for long-distance transmission and based on the selected technology, the device will be designed. According to selected components, its power supply will be designed with the aim of long-term functionality and continuous operation.

Long-term trends in sulphur and nitrogen wet deposition - a comparison of Northern Hemisphere regions
Vlnasová, Eliška ; Hůnová, Iva (advisor) ; Kaňa, Jiří (referee)
This scientific literature review examines the time trends of wet atmospheric deposition of sulphur and nitrogen over a four decade period in three regions of the Northern Hemisphere, namely Europe, North America and Southeast Asia. The wet atmospheric deposition processes transport sulphur and nitrogen compounds from the atmosphere to the Earth's surface via vertical or horizontal pathways. Excessive levels of these deposited compounds can cause a number of environmental problems, such as change in biodiversity, degradation of forest stands or change in water and soil chemistry. It is therefore necessary to monitor and evaluate these trends. Sulphur and nitrogen can enter the atmosphere through anthropogenic emissions, among other sources. The change in sulphur and nitrogen emissions over the last four decades has undoubtedly influenced the time trends of wet deposition. The aim of this work is to evaluate these patterns in addition to the sulphur and nitrogen trends. This work also addresses the change in wet deposition ion ratios, in particular the change in the ratio of NH4 + to NO3 - in the wet deposition of nitrogen. Wet deposition of sulphur, in line with a significant reduction in sulphur compounds emissions, records a noticeable decrease in both Europe and North America, but wet...
