Making knowledge about evolution available to everyone, this simple and entertaining book offers answers to the most frequently asked questions. Throughout the text, the reader is reminded of the importance of understanding evolutionary processes in order to approach present day human behavior, including social conduct, as well as the difficulty of trying to decipher the nature of modern human beings without going back to their zoological origin. Divided into two sections, the first one builds the foundation for the latter, which explains the evolution of life, beginning at the physical...

This thesis (written in Spanish) presents the analysis, design and implementation of a four-quadrant power supply with high-frequency isolation, which is expected to be used to feed the low-energy correction magnet of a particle accelerator. In particle accelerator applications the magnetic field during beam acceleration may be either positive or negative, and true bipolar power converters are needed. The selected bipolar topology consists of a bidirectional three-phase to single-phase reduced matrix converter (RMC) with power factor correction and a bidirectional active rectifier. Main...
