RFID equipped security terminal
Vařečka, Radek ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
The concept proposal of the RFID security terminal is described in this Master Thesis. The RFID identification and its usage are analyzed at first. The description of the selected fitting circuits, communication bus as well as its parameters follows. The practical realization, proposed module design and designed printed circuit board is described afterwards. Several problems found during activation phase are analyzed in the chapter describing the practical module realization. The problem resolution is mentioned as well. The practical prove of the real module parameters and differences compared to the designed values are described at the end of this Master Thesis.

Microcontroller based system equipped by MEMS accelerometer
Vrobel, Jan ; Šír, Michal (referee) ; Bradáč, Zdeněk (advisor)
The object of this thesis is the implementation of the measurement system based on MEMS acceleration sensor and a microcontroller. In the individual chapters of the thesis is described the process of implementation from the initial conceptual design to electronics design, selection of components, to the implementation of the PCB. The device is designed as a miniature battery-powered device with wireless data interface. There is also described the implementation of the firmware demonstrating the functionality of the system and the PC application to communicate with the device.

Multi-spectral analysis of a gamma-ray burst
Maleňáková, Alžběta ; Jelínek, Martin (advisor) ; Münz, Filip (referee)
Gamma-ray bursts are fascinating high energy phenomena, related with supernovas and black holes, which were discovered by accident in the second half of the 20. century. The goal of this thesis is to perform a multi-spectral analysis of the GRB 190919B after becoming familiar with the elementary knowledge about this phenomena. The images of an optical afterglow from robotic telescopes FRAM and BOOTES enabled us to construct the photometric light curve of the given burst. Together with the publicly available data from other spectral fields, the spectral energy distribution could be created. Afterwards, we fitted both obtained graphs with several functions with different choices of constraining parameters. Through analysis of the acquired values, we obtained several variants of the scenario of the observed event. By determining the value of initial Lorentz factors, we confirmed that all the options lie within the boundaries of typical values for the model of relativistic fireball. 1
