Vertically polarized Yagi antenna with magnetic dipole
Weigel, Filip ; Pokorný, Michal (referee) ; Raida, Zbyněk (advisor)
This bachelor’s thesis deals with the principles of operation and simulation of planar Yagi antennas with a magnetic dipole. Simulation of electromagnetic field was performed in the simulator CST MICROWAVE STUDIO (CST MWS). The project compares results of simulations of several types of Yagi antennas. These antennas can be used for the communication along the living tissue (on-body communication).

Reconfigurable slot antenna array
Weigel, Filip ; Pítra, Kamil (referee) ; Raida, Zbyněk (advisor)
This master's thesis deals with the basic principles of slot antennas. Models of antennas were simulated in a selected electromagnetic simulator CST MICROWAVE STUDIO (CST MWS). There are several models of slot antennas which are optimized for communication in the car at a frequency 8 GHz.

ESP/ESC Impact to Behavior of Vehicle
Weigel, Filip ; Mrázek, Vojtěch (referee) ; Strnadel, Josef (advisor)
This bachelor thesis focuses on active safety - ESP. System ESP greatly improves stability of vehicle while turning. The thesis analyses modelling, brake functionality, subordinate systems of ESP - ABS and ASR, physical forces and phenomenons, model example, analysis of problem, design of model, implementation of model and experiments evaluation of implemented model in UPPAAL enviroment. The goal of the thesis is to prove that ESP system helps to stabilize vehicle while turning by simulation of vehicle model. Results are presented in well-aranged graphs side-by-side. It is possible to analyze the behaviour of vehicle while turning with ESP or without ESP.

Risk Analysis of Self-Driven Vehicles
Weigel, Filip ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The goal of this thesis was to design and implement system for risk analysis in self-driving cars. This thesis focused on design and implementation of system for risk analysis in models. One of the requirements for the system was to be flexible and robust. Design of the risk analysis was presented at theoretical level and then implemented in models of ABS and ESP systems in UPPAAL environment. The system was then tested via multiple experiments. The experiments were beneficial and the system for risk analysis correctly evaluated failure scenarios with adequate response to the rising level of risk. Experiment outputs were then presented at graphs with comment to each failure scenario.
