Design of 6 ½ digit multimeter
Petrek, Martin
Paper summarizes individual parts of DMM (digital multimeter) and how they work. Design approach in comparison to commercial solution is in the thermal stabilization of the whole analog assembly. DMM has 8 custom designed PCBs (printed circuit board): Processor PCB, Keyboard and input backlit PCB, Analog PCB, Voltage reference PCB, Thermostat PCB, AC/DC PCB and LDO (Low dropout voltage regulator) PCB. User interface, program, thermal stabilization and mechanical construction are also described.

Amalysis of migration flows in Sub-Saharan Africa in 2019
Petřek, Martin ; Hasman, Jiří (advisor) ; Pavelková, Lenka (referee)
Analysis of Migration Flows in Sub-Saharan Africa in 2019 Abstract The aim of this thesis will be the analysis of migration flows in sub-Saharan Africa in 2019. Based on the research, we can state what factors most influence spatial migration in sub- Saharan Africa. The basic factors are determined based on the study of the literature and are clearly divided into cultural, political, socio-economic and geographical factors. Fifty-four of the most intensive migration flows in this region are subsequently analyzed. Based on the characteristics of the source and destination countries, we will get an answer to the questions of which factors influence migration flows the most and which influence them the least. The result is a confirmation of the importance of mainly cultural and geographical factors, for example a common religion, an official language or common borders and distance. A smaller influence was shown for socio-economic and political factors, especially for the degree of freedom or the poverty index and the smallest influence for common historical ties. Keywords: destination country, migration flows, migration geography, source country
