A Tensioner for the B-ISG System presents the design and analysis of a Twin Tensioner for a Belt-driven Integrated Starter-Generator (B-ISG) system. The B- ISG is an emerging hybrid transmission closely resembling conventional serpentine belt drives. Models of the B-ISG system's geometric properties and dynamic and static states are derived and simulated. The objective is to reduce the magnitudes of static tension in the belt for the ISG-driving phase. A literature review of hybrid systems, serpentine belt drive modeling and automotive tensioners is included. A parametric study evaluates tensioner parameters with respect to their impact on static tensions. Design variables are selected from these for an optimization study. The optimization uses a genetic algorithm (GA) and a hybrid GA. Results of the optimization indicate that the optimal system contains spans with static tensions that are significantly lower in magnitude than that of the original design. Implications of the research on future work are discussed in closing.

Over the last few decades, research on labour migration has experienced excessive domination by economic explanation. Econometric analysis has been such a dominant factor in the studies of international labour migration that the very language of analysis tends to marginalize social and cultural factors. Focusing on Bangladeshi labour migration to Singapore, this book, therefore, addresses the socio-cultural forces that influence migration motivation, the social experiences that shape the lives of these migrants overseas, and the developmental implications that bring about in migrant families back home. The analysis should help shed light on some key issues such as migration decision-making, migrant networks, social life of migrants on foreign soil, migration and poverty, and migration and social development from a multidisciplinary perspective, and should be especially useful to students, researchers, policy makers, journalists, and the general scholars, who have interest in migration studies. In addition to migration scholars, this book will have an appeal to the scholars who broadly deal with social changes in developing countries.
