Accumulator tester with ESP32 module
Dresler, Jan ; Musil, Petr (referee) ; Lattenberg, Ivo (advisor)
This thesis focuses on design of printed circuit board and programming of ESP32 module. This module communicates with discharging circuit which allows testing of battery properties. With help of voltage and current sensors it is possible to test and print results of battery on display. The testing device also allows control over web user interface thanks to ESP32.
Water resources of Kyrgyzstan as a geopolitical tool
Dresler, Jan ; Jelen, Libor (advisor) ; Anděl, Jiří (referee)
The thesis deals with the importance of water resources and their influence on political development with the example of Kyrgyzstan. The main objective was to find out the role of water resources in domestic politics, how water influences the relationship between Kyrgyzstan and its neighbors, and whether water resources are of interest to the world's superpowers. Geopolitical analysis was carried out on three levels. At national level, water scarcity, uneven distribution and obsolete water systems are a cause of civil discontent. Corruption in the state sphere negates the possibility of modernization of existing water facilities. Water management is dependent on non-governmental associations and foreign financial assistance. At regional level, there is constant tension between Kyrgyzstan, where all the important rivers of the region rise, and the states lying downstream of these rivers. The cause of this tension is different demands of individual states on water use. International treaties address the situation, but are mostly non-functional in the long term. At the supra-regional level, the interests of especially Russia and China collide. Both superpowers seek to prevent US influence in the region. At the same time, they gain a dominant position in Kyrgyzstan in the economic and security spheres....
Geopolitics of water resources in Syr Darya river basin
Dresler, Jan ; Jelen, Libor (advisor) ; Vogt, David (referee)
Water belongs to renewable resources, but its allocation in the world is unequal and some regions have been already suffering from water scarcity. It brings rising tensions and conflict situations. The study describes geopolitical problems concerning economic or other usage of water resources in the Syr Darya river basin, Central Asia, from a geopolitical point of view. Its goal is to analyse present situation and to estimate possibilities of regional and supra- regional cooperation among the states located in the river basin. Cooperation on the local level is not possible because of Uzbekistan, who plays a role of a strong regional leader. Cooperation on the supra-regional level is possible but it can be influenced by Russia or China. The presumable future development concerning regional security situation is discussed. The risk of potential military conflict due to water scarcity as well as additional problems in the region is high. Key words: water resources, geopolitics, Syr Darya river basin, Central Asia
Programmable timer configurable via USB
Dresler, Jan ; Číž, Radim (referee) ; Lattenberg, Ivo (advisor)
This thesis describes the design of printed circuit boards and programming AVR microcontroller, that communicates with the digital thermometer Dallas, also with photoresist circuit and RTC. Using sensors and relay allows switching of different devices. The switch allows direct configuration with computer via USB using the auxiliary circuit UART.
