Self Steering

If you are thinking of fitting an autopilot or windvane steering system to your boat but are baffled as to which is the most suitable, then this is the book for you. Peter Forthmann, a long-term expert on this subject, explains the difference between tiller, wheel and inboard autopilots, as well as the 12 windvane steering options available, and considers their suitability for various types of boat and sea conditions. Which self-steering systems are more suitable for cruising and which for racing? What are their limitations in terms of sea conditions and power consumption? What is yaw damping? Why are windvane steering systems unsuitable for ULDBs? How do you steer a catamaran without running into power consumption problems? Why is good sail trim so important for good self-steering? What self-steering provisions should you make when building a boat? Is DIY windvane gear construction still a feasible option? All these questions and many more are answered in this very comprehensive book, which concludes with a comparison of all the alternatives available and a list of manufacturers of practically every self-steering system made anywhere in the world. Peter Christian Forthmann has a unique knowledge of self-steering. Born in 1947, he learned to sail as soon as he learned to walk, growing up by the water in Hamburg. An engineer and a highly practical man, Peter Forthmann's creative contribution to the evolution of windvane steering systems is virtually unparalleled. lt is thanks in no small part to him that these systems are still thriving in the age of bits and bytes.

In the on-going philosophical debate between cognitivism and (radical) constructivism the pervading notions of self-reference, self- organization, self-steering, autonomy, etc., are at the forefront of discussion. These multidisciplinary papers, from a symposium on [title] held in May 1987, examine these topics in depth and illustrate their applications. Taken as a whole, they provide insight into the emergence of a new cybernetics. Book club price, $34. Annotation copyrighted by Book News, Inc., Portland, OR

In spite of all the assistance offered by electronic control systems, the latest generation of passenger car chassis still relies on conventional chassis elements. With a view towards driving dynamics, this book examines these conventional elements and their interaction with mechatronic systems. First, it describes the fundamentals and design of the chassis and goes on to examine driving dynamics with a particularly practical focus. This is followed by a detailed description and explanation of the modern components. A separate section is devoted to the axles and processes for axle development. With its revised illustrations and several updates in the text and list of references, this new edition already includes a number of improvements over the first edition.

Chinas Einsatz von Industriepolitik hat die Debatte über staatliche Intervention in der Wirtschaft neu entfacht. Nur wenige Branchen erleben die lenkende Hand des Staates wie der chinesische Elektrizitätssektor. Dieser sieht sich aber einem radikalen Umbruch ausgesetzt. Der Begriff "Smart Grid" umfasst technische und systemische Reformen, die für einen Strukturwandel erforderlich sind. Diese Studie untersucht durch die Linse der Steuerungstheorie die Auswirkungen einer Gesetzgebung auf Machtkämpfe im Elektrizitätssektor Chinas. Anhand von Dokumentenanalyse und Interviews wird der Frage nachgegangen, wie Steuerungsprozesse durchgeführt und Gegensteuerungsstrategien entwickelt werden, um Verhandlungen auf politischer Ebene zu beeinflussen.
