The measurement of melanopic quantities in indoor spaces with the luminance analyser LDA - LumiDISP
Siegel, Josef ; Baxant, Petr (referee) ; Motyčka, Martin (advisor)
This thesis focuses on measuring melanopic quantities in indoor spaces and their impact on individuals and their circadian rhythms. Melanopic quantities are specific parameters of light that influence biological responses and physiological processes in our bodies. To measure these quantities, a photometric analyzer is utilized, enabling the quantification of spectral components of light. It also evaluates the melanopic contributions of various lighting sources, such as LED fixtures, incandescent bulbs, or natural daylight.

Protection functions of the REX 640 terminal in case of earth faults
Siegel, Josef ; Bukvišová, Zuzana (referee) ; Wasserbauer, Vojtěch (advisor)
This bachelor thesis deals with the protection, implementation and evaluation of test for fault condition indicators. Thesis focus on earth fault indicators. These protections must be able to evaluate earth faults in compensated, compensated with auxiliary resistor, unearthed and high-resistance earthed networks. Furthermore, part of the thesis is research of methods of earth fault detection, including their principles and function description.
