Thermodynamic Sensors Based on the Principle of Balance Equilibrium
Řezníček, Michal ; Husák, Miroslav (referee) ; Banský,, Juraj (referee) ; Szendiuch, Ivan (advisor)
This paper deals with the problem of monitoring the occurrence of the minority events in thermodynamic systems by using thermodynamic sensors based on the principle of balance equilibrium. The basis of this work is to find new sensor arrangement of thermodynamic sensors that allows work in a wide range of workloads of monitored system while maintaining the required sensitivity. Newly designed balance circuit for the sensor arrangement with four active sensors allows active setup of the default balance equilibrium and power matching of the sensor to its immediate surroundings in the system. By designing and optimization of balance circuit was achieved measuring the output response and its conversion to digital format. This enabled numerical analysis of output signal, algorithmic processing of the results and generate a feedback control signal to adjust the equilibrium conditions.

GPS telemetry and activity measurement focused on even-toed ungulates (Artiodactyla)
Peterka, Tomáš ; Bartoš, Luděk (advisor) ; Komárková, Martina (referee)
GPS telemetry is a recently expanding method for research on most animal species. It provides automatical scanning of position and related data on large distances and often on large temporal scale. The research studies has changed dramatically during the development of this method. Experiments using this technology deal with scanning of incidence, management and species conservation, activity pattern of controlled animals, estimation of behavior in various scales and so on. Activity sensors which are often included to GPS collars serve for determination of behavior of monitored species. In this thesis there are summarized basics of VHF and GPS technology. In available articles of great terrestrial mammals like even-toed ungulates (Artiodactyla) and marginally also bears (Ursidae) we show possible application of GPS technology for activity measurement, methods, restrictions and results of experiments. At the end we introduce experimental approach for activity measurement of red deer (Cervus elaphus) and results of the pilot study.
