Patterns of Im/mobility, Conflict and Identity - - Bog - Taylor & Francis Ltd - Plusbog.dk

Patterns of Im/mobility, Conflict and Identity - - Bog - Taylor & Francis Ltd - Plusbog.dk

Patterns of im/mobility, collective identity and conflict are highly entangled. The im/mobility of a social or cultural group has major impact on how identity narratives, a sense of belonging and relationships to ‘others’ are shaped, and vice versa. These dynamics are closely interlinked with mechanisms of inclusion and exclusion between groups and power structures that involve a broad variety of actors from local populations, to migrants, government institutions and other intermediaries. Mainly looking at patterns of internal mobility such as ‘traditional’ or strategic mobilities and mobilities enforced by crisis, conflict or governmental programmes and regimes, this book aims to go beyond currently predominant issues of transnational migration. Dynamics of non/integration and belonging, caused by im/mobility, are analysed on a cultural and political level, which involves questions of representation, indigeneity/autochthony, political rights and access to land and other resources. With ethnographic case studies from Kosovo, Sierra Leone, Liberia, Bangladesh, East Timor and Indonesia, this volume provides a comparative perspective on the multifold dimensions of im/mobility in contexts where changing mechanisms of inclusion and exclusion trigger or settle conflicts and social identities are constantly re/negotiated. The chapters in this book were originally published as a special issue of Social Identities .

Feminist (Im)Mobilities in Fortress(ing) North America - Marianne H. Marchand - Bog - Taylor & Francis Ltd - Plusbog.dk

Feminist (Im)Mobilities in Fortress(ing) North America - Marianne H. Marchand - Bog - Taylor & Francis Ltd - Plusbog.dk

Since the establishment of the North American Free Trade Agreement (NAFTA) tensions concerning immigration trends and policies, which continued to escalate at the turn of the millennium resulted in revised national security policies in Mexico, Canada, and the United States. These tensions have catalyzed the three governments to rethink their political and economic agendas. While national feminist scholarship in and on these respective countries continue to predominate, since NAFTA, there has been increasing feminist inquiry in a North American regional frame. Less has been done to understand challenges of the hegemonies of nation, region, and empire in this context and to adequately understand the meaning of (im)mobility in people''s lives as well as the (im)mobilities of social theories and movements like feminism. Drawing from current feminist scholarship on intimacy and political economy and using three main frameworks: Fortressing Writs/Exclusionary Rights, Mobile Bodies/Immobile Citizenships, and Bordered/Borderland Identities, a handpicked group of established and rising feminist scholars methodically examine how the production of feminist knowledge has occurred in this region. The economic, racial, gender and sexual normativities that have emerged and/or been reconstituted in neoliberal and securitized North America further reveal the depth of regional and global restructuring.

Electric Machines - Ion Boldea - Bog - Taylor & Francis Ltd - Plusbog.dk

This Second Edition extensively covers advanced issues/subjects in electric machines, starting from principles, to applications and case studies with ample graphical (numerical) results. This textbook is intended for second (and third) semester courses covering topics such as modeling of transients, control principles, electromagnetic and thermal finite element analysis, and optimal design (dimensioning). Notable recent knowledge with strong industrialization potential has been added to this edition, such as: - - Orthogonal models of multiphase a.c. machines - - - Thermal Finite Element Analysis of (FEA) electric machines - - - FEA–based–only optimal design of a PM motor case study - - - Line start synchronizing premium efficiency PM induction machines - Induction machines (three and single phase), synchronous machines with DC excitation, with PM-excitation, and with magnetically salient rotor and a linear Pm oscillatory motor are all investigated in terms of transients, electromagnetic FEM analysis and control principles. Case studies, numerical examples, and lots of discussion of FEM results for PMSM and IM are included throughout the book. The optimal design is treated in detail using Hooke–Jeeves and GA algorithms with case comparison studies in dedicated chapters for IM and PMSM. Numerous computer simulation programs in MATLAB ® and Simulink ® are available online that illustrate performance characteristics present in the chapters, and the FEM and optimal design case studies (and codes) may be used as homework to facilitate a deeper understanding of fundamental issues.

Modeling and Control of AC Machine using MATLAB /SIMULINK - Mourad Boufadene - Bog - Taylor & Francis Ltd - Plusbog.dk

Modeling and Control of AC Machine using MATLAB /SIMULINK - Mourad Boufadene - Bog - Taylor & Francis Ltd - Plusbog.dk

This book introduces electrical machine modeling and control for electrical engineering and science to graduate, undergraduate students as well as researchers, who are working on modeling and control of electrical machines. It targets electrical engineering students who have no time to derive mathematical equations for electrical machines in particular induction machine (IM) and doubly fed induction machines (DFIM). The main focus is on the application of field oriented control technique to induction motor (IM) and doubly fed induction motor (DFIM) in details, and since the induction motors have many drawback using this technique, therefore the application of a nonlinear control technique (feedback linearization) is applied to a reduced order model of DFIM to enhance the performance of doubly fed induction motor. Features - - Serves as text book for electrical motor modeling, simulation and control; especially modeling of induction motor and doubly fed induction motor using different frame of references. - - - Vector control (field oriented control) is given in more detailed, and is applied to induction motor. - - - A nonlinear controller is applied to a reduced model of an doubly induction motor associated with a linear observer to estimate the unmeasured load torque, which is used to enhance the performance of the vector control to doubly fed induction motor. - - - Access to the full MATLAB/SIMULINK blocks for simulation and control. -
