Bottom-up Responses to Crisis - - Bog - Springer Nature Switzerland AG - Plusbog.dk

Crises occur in all societies across world, and can be natural (such as hurricanes, flooding, and earthquakes), man-made (such as wars and economic downturns), or, often, a combination of both (such as famines, the flooding of New Orleans in 2005 after Hurricane Katrina and subsequent levy failures, and the earthquake, tsunami, and nuclear disaster in Japan in 2011). Crises cause fatalities, injuries, and property damages as well as introduce uncertainty and challenges for individuals, societies, and polities. Yet, we see individuals and communities rebounding effectively from crises all the time. How do communities go about returning to normalcy and beginning again the mundane life of every day affairs? This edited volume looks at bottom-up responses to crises. The chapters in this volume will highlight the ingenuity and persistence of individuals and private organizations as well as discuss the possibilities, limitations, and adaptability of bottom-up responses. It argues that there are many ways that local leaders, entrepreneurs, and community members can play a role in their own recovery by examining the capabilities, feedback mechanisms, and network effects of decentralized crisis response and recovery efforts. Chapters will focus on the role of local emergency managers in the disaster management process and offer suggestions for reform and the role of businesses, citizens, and children in providing crisis response and recovery. This book will also consider theories of self-governance and nonviolent action in encouraging and sustaining bottom-up recovery.

Gears - Vincenzo Vullo - Bog - Springer Nature Switzerland AG - Plusbog.dk

This book explores the geometric and kinematic design of the various types of gears most commonly used in practical applications, also considering the problems concerning their cutting processes. The cylindrical spur and helical gears are first considered, determining their main geometric quantities in the light of interference and undercut problems, as well as the related kinematic parameters. Particular attention is paid to the profile shift of these types of gears either generated by rack-type cutter or by pinion-rack cutter. Among other things, profile-shifted toothing allows to obtain teeth shapes capable of greater strength and more balanced specific sliding, as well as to reduce the number of teeth below the minimum one to avoid the operating interference or undercut. These very important aspects of geometric-kinematic design of cylindrical spur and helical gears are then generalized and extended to the other examined types of gears most commonly used in practical applications, such as straight bevel gears; crossed helical gears; worm gears; spiral bevel and hypoid gears. Finally, ordinary gear trains, planetary gear trains and face gear drives are discussed. This is the most advanced reference guide to the state of the art in gear engineering. Topics are addressed from a theoretical standpoint, but in such a way as not to lose sight of the physical phenomena that characterize the various types of gears which are examined. The analytical and numerical solutions are formulated so as to be of interest not only to academics, but also to designers who deal with actual engineering problems concerning the gears
