Comparison of different types of commercial lithium-ion batteries and their properties under low temperature
Bičák, Tomáš ; Máca, Josef (referee) ; Libich, Jiří (advisor)
The diploma thesis deals with the issue of lithium-ion batteries. Describes development, technologies and materials used. The diploma thesis describes the operating principle, characteristics, advantages and disadvantages. The work is focused on the characteristic properties of commercial lithium-ion batteries under standard conditions and at reduced temperatures. At reduced temperatures, changes in properties due to low temperatures are observed. Furthermore, in this work they compare the measured values with the values given by the manufacturers.

Dedicated VoIP communicator
Bičák, Tomáš ; Číka, Petr (referee) ; Caha, Tomáš (advisor)
The aim of the bachelor thesis was to build a VoIP communicator. This VoIP communicator is built on a Raspberry Pi Zero device with an external sound card. Raspbian operating system is installed on the Raspberry Pi. The PJSIP library is used as the software basis for VoIP communication. The created software allows you to automatically answer a call and make a call to defined addresses. The call is made after pressing the button.
