This document summarizes Gabriel Aroeira Ferreira's work improving brake systems through experiments and analysis. It describes tribometer tests to measure friction coefficients under different pressures, velocities, and durations. Microscope images show the surface of samples before and after testing under various conditions. MATLAB was used to analyze the data. The document also discusses Gabriel's experiences in Germany, including visiting cities, learning the language, experiencing different cultures through an exchange program, making new friends, and sharing stories.
