PEM Water Electrolysis explores technology gaps in the development of commercially viable PEM electrolysis systems for energy applications. This volume--from the popular Hydrogen Energy and Fuel Cell Primers series--brings together information from different sources, making it a useful reference for industry professionals, researchers and graduate students alike. It examines the fundamentals of PEM electrolysis and select research topics of interest in related academic and industry communities, such as gas crossover and AST protocols, laying the foundation for the exploration...

The eyes of the world are on the Middle East. Today, more than ever, this deeply-troubled region is the focus of power games between major global players vying for international influence. Absent from this scene for the past quarter century, Russia is now back with gusto. Yet its motivations, decision-making processes and strategic objectives remain hard to pin down.

So just what is Russia up to in the Middle East? In this hard-hitting essay, leading analyst of Russian affairs Dmitri Trenin cuts through the hyperbole to offer a clear and nuanced analysis of Russia's involvement in...

Since the outbreak of the Ukraine crisis, there has been much talk of a new Cold War between the West and Russia. Under Putin's authoritarian leadership, Moscow is widely seen as volatile, belligerent and bent on using military force to get its way.

In this incisive analysis, top Russian foreign and security policy analyst Dmitri Trenin explains why the Cold War analogy is misleading. Relations between the West and Russia are certainly bad and dangerous but - he argues - they are bad and dangerous in new ways; crucial differences which make the current rivalry between Russia,...

The present book outlines a new approach to possibilistic clustering in which the sought clustering structure of the set of objects is based directly on the formal definition of fuzzy cluster and the possibilistic memberships are determined directly from the values of the pairwise similarity of objects. The proposed approach can be used for solving different classification problems. Here, some techniques that might be useful at this purpose are outlined, including a methodology for constructing a set of labeled objects for a semi-supervised clustering algorithm, a methodology for reducing...
