This book focuses on water content estimation and control of the PEM fuel cell stack and the individual cell in vehicle. Firstly, the mathematical connection between polarization curve and equivalent circuit model proves importance of MEA and its feasibility to study water content. Optimizing structure of MEA realizes the internal water content recirculation of a fuel cell and improves its performance under middle or lower current density. The influence of water content on performance of MEA is quantified, and variation of equivalent circuit model is an excellent indicator of water...

Driven by the need to achieve superior control performances for robots with hyper degrees of freedom, the virtual decomposition control approach is thoroughly presented in this book. This approach uses subsystem (such as links and joints of a complex robot) dynamics to conduct control design, while guaranteeing the stability and convergence of the entire complex robot without compromising the rigorousness of the system analysis. The central concept of this approach is the definition of the virtual stability. The stability of the entire complex robot is mathematically equivalent to the...

This book is devoted to the cultural and biological dimensions and values of landscapes, linking the concepts of biodiversity, landscape and culture and presenting an essential approach for landscape analysis, interpretation and sustainable dynamics.

Early chapters explore the concepts and values of biocultural landscapes, before addressing the methodology to identify the relationship between biological and cultural diversity. The volume continuous with a series of case studies and with an exploration of the key role of biocultural diversity in contemporary landscape...

This is the first in-depth global study of women's football across the world. This collection considers women's football, in fifteen countries worldwide, in a global context, and analyzes its progress, challenges and problems it has faced.

It shows how women's football has made a significant contribution to the emancipation of women's football in many countries. It also traces the evolution of women's football in face of resistance, rejection and prejudice and describes women footballer's struggle for equal rights in a male dominated football world.
