Sommario/riassunto |
|
"Younger generations across a wide range of societies face increasing difficulties in gaining access to housing. Housing occupies a pivotal position in the transition from parental dependence to adult independence. Delayed independence has significant implications for marriage and family formation, fertility, inter and intra generational tensions, social mobility and social inequalities.The social and cultural dimensions are, of course, enormously varied with strong contrasts between Asian and Western societies in terms of intergenerational norms and practices in relation to housing. Nevertheless, younger households in China (including Hong Kong), Japan, the USA, Australasia and Europe face very similar challenges in the housing sphere. Moreover, concerns about the housing future for younger generations are gaining greater policy and popular prominence in many countries. All the papers were specially commissioned for a symposium in Hong Kong which took place in summer 2011. This brought together a small group of specially invited international experts, in a round table format, to explore the specific institutional, economic and cultural factors at work in different national contexts.

Sommario/riassunto |
|
"This book is an in-depth essential reference of rotating electrical machine design theory and application. In the first part of the book the general theory governing the design of an electrical machine is presented; addressing the necessary fundamentals of electromagnetic theory; exploring possible winding arrangements and resistances; describing the behaviour of the magnetic circuit and flux leakage. After this introduction of principles the main body of the book focuses on the design of a rotating electrical machine. The book defines basic characteristics such as machine type (e.g. synchronous, asynchronous, DC and doubly salient reluctance machines) and type of construction (e.g. external pole, internal pole, axial flux and radial flux machines). It then moves on to provide a detailed analysis of the design process and properties of rotating electrical machines including the insulation and heat removal options. The book illustrates the necessary analytical calculations for machine design through direct design examples i.e. a permanent magnet motor for normal speeds with rotor surface magnets, traditional squirrel cage induction motor, a low speed high torque fractional slot permanent magnet motor etc."-- |
