This book explores PEM fuels cells and their potential in the energy transition. PEM fuel cells are electrochemical devices that can harness hydrogen energy and transform it into electricity.The book is divided into three. The first section looks into the fundamentals of PEM fuel cells.The second explores computational fluid dynamics (CFD) modeling of the dynamics of them. Every section of this book contains illuminating illustrations and informative tables. The final secti...

This book describes the benefits and drawbacks inherent in the use of virtual platforms (VPs) to perform fast and early soft error assessment of multicore systems. The authors show that VPs provide engineers with appropriate means to investigate new and more efficient fault injection and mitigation techniques. Coverage also includes the use of machine learning techniques (e.g., linear regression) to speed-up the soft error evaluation process by pinpointing parameters (e.g., architectural) ...

Casimir effects serve as primary examples of directly observable manifestations of the nontrivial properties of quantum fields, and as such are attracting increasing interest from quantum field theorists, particle physicists, and cosmologists. Furthermore, though very weak except at short distances, Casimir forces are universal in the sense that all material objects are subject to them. They are thus also an increasingly important part of the physics of atom-surface interactions, while in ...
