This book tells the story of the power generation gas turbine from the perspective of one of the leading companies in the field over a period of nearly 100 years, written by an engineer. Especially in times of imminent global economic crises it appears to be worthwhile to reflect on real economic values based on engineering ingenuity and enduring management of technological leadership. Though the book is primarily designed as a technical history of the BBC/ABB/Alstom power generation gas turbines, its scope is sufficiently broad to cover general development trends, including parallel competitor activities. A special benefit is the historical breakdown to the gas turbine component level, so that the book actually outlines the development of axial compressors from early beginnings, the progress in combustion technology towards extraordinary low emission values and that of axial turbines with special emphasis on early turbine cooling innovations.The sheer length of certain engineering developments over several decades allows interesting historic observations and deductions on inherent business mechanisms, the effects of technology preparations and organisational consequences. A look into the mirror of the past provides revelations on the impact of far-reaching business decisions. 2017 Winner of the Historian Engineer Award of the ASME (American Society of Mechanical Engineers

This book aims to incorporate an emerging successful business model, i.e., sharing economy, into energy markets, thus digging out the potential merits and applications in multi-energy sectors. With the core idea "e;access over ownership"e;, sharing economy enables the collaborative consumption of idle resources through advanced information and communications technology. One critical challenge is to identify different market participants' occupation while accordingly designing pricing mechanisms. This book begins with an overview about the recent development of sharing economy in energy fields, and summarizes two energy market-related issues that sharing economy can hopefully address. One is how to quantify a marginal generator's contribution and thereby elicit truthful bidding under information asymmetry condition. The other is how to distinguish renewable and distributed energy resources' contribution and thus incentivize efficient aggregation considering increasing scale and uncertainty. Then sharing economy mechanisms are proposed and designed from a game theory perspective. On this basis, the following chapters thoroughly investigate the specific problems in spot markets, multi-area markets, renewable energy aggregation and energy systems integration. Additionally, the benefits brought by sharing economy are evaluated in terms of regional market bidding and transmission expansion deferral. Finally, the information and communications technologies related to sharing economy are modeled and analyzed. Hopefully, this book can greatly benefit the readers who are interested in energy economics and engineering.

Sur un sol inégal, les robots à pattes ont le potentiel d'être une machine à marcher. Le mécanisme de Theo Jansen, qui se compose de onze barres de liaison, reproduit un mouvement de marche régulier appelé "démarche". Les mouvements parallèles sont couramment utilisés dans les machines lourdes et ont récemment été mis en évidence dans un modèle de mouvement biologique. En raison du problème de singularité, la connexion en boucle fermée ne donne que la trajectoire d'un effecteur conçu, qui est censé être moins modifiable. La singularité du mécanisme Theo Jansen modifié a été abordée dans cette étude en introduisant l'orbite paramétrique comme nouveau point de liberté au centre de l'articulation, et la dynamique multi-corps a été utilisée pour examiner sa cinématique et sa dynamique (MBD). Dans la simulation numérique, l'extensibilité du mécanisme en termes de flexibilité de la trajectoire de marche a été clairement établie, donnant lieu à de nouvelles trajectoires de marche fonctionnelles contrôlées par deux paramètres de contrôle qui modifient la forme de l'ovale paramétrique au centre de l'articulation.

Das rasante Wachstum der Technologie in den letzten zwei Jahrzehnten ist durch FMS und Material Handling gekennzeichnet. Da nur die wohlhabenden und entwickelten Länder es sich leisten können, eine vollständige Automatisierung einzuführen, ist eine große Produktivitätslücke entstanden. Das Bestreben, die Produktivität zu steigern, kann durch die Einführung kostengünstiger Automatisierungslösungen in den für sie charakteristischen kleinen und mittelständischen Unternehmen wirksam umgesetzt werden. Man schätzt, dass mindestens 15 bis 25 % der Produktkosten auf den Materialtransport entfallen. Im Gegensatz zu vielen anderen Vorgängen trägt der Materialtransport zu den Kosten des Produkts bei und nicht zu dessen Wert. Die richtige Konstruktion und Entwicklung von Materialhandhabungssystemen, die die Ermüdung des Bedieners erheblich verringern können, machen die Materialhandhabung sicherer und erhöhen gleichzeitig die Produktivität.
