Emisivity and its Impact on the Heat Conductivity
Gančev, Jan ; Hejátková, Edita (referee) ; Szendiuch, Ivan (advisor)
This work deals with the issue of emissivity and its impact on the heat dissipation.The first part describes the basics of thermal management, the issue of emissivity and its measurement. In the second, experimental part, are dedicated the emissivity values of examined specimens. These values are then used as initial conditions for the thermal simulation. In the last part are compared the measured results and the simulated results and is evaluated the impact of emissivity for the heat dissipation.

Practical implementation of symmetrical regulated supply
Pekarovič, Ján ; Vochyán, Josef (referee) ; Petržela, Jiří (advisor)
This thesis deals with a stabilized power supply capable of maintaining the output voltage from 0 V to 30 V. It is suggested as two independent adjustable power supply that can interlock to create a symmetric stabilized source. The described source is provided with electronic fuse to protect the connected device and the source itself from destruction. Part of this work is the simulation suggested time diagram for theoretical verification of functionality, design of circuit boards, cooling and case and basic measurement results on the realized power supply.
