This is the first book to introduce the irrational elliptic function series, providing a theoretical treatment for the smooth and discontinuous system and opening a new branch of applied mathematics. The discovery of the smooth and discontinuous (SD) oscillator and the SD attractors discussed in this book represents a further milestone in nonlinear dynamics, following on the discovery of the Ueda attractor in 1961 and Lorenz attractor in 1963. This particular system bears significant similarities to the Duffing oscillator, exhibiting the standard dynamics governed by the hyperbolic structure associated with the stationary state of the double well. However, there is a substantial departure in nonlinear dynamics from standard dynamics at the discontinuous stage. The constructed irrational elliptic function series, which offers a way to directly approach the nature dynamics analytically for both smooth and discontinuous behaviours including the unperturbed periodic motions and th e perturbed chaotic attractors without any truncation, is of particular interest. Readers will also gain a deeper understanding of the actual nonlinear phenomena by means of a simple mechanical model: the theory, methodology, and the applications in various interlinked disciplines of sciences and engineering. This book offers a valuable resource for researchers, professionals and postgraduate students in mechanical engineering, non-linear dynamics, and related areas, such as nonlinear modelling in various fields of mathematics, physics and the engineering sciences.

Non Destructive Testing and Non Destructive Evaluation using Ultrasounds covers an important field of applications and requires a wide range of fundamental theoretical, numerical and experimental investigations. In the present volume, the reader will find some relevant research results on wave propagation in complex materials and structures which are concerned with today's problems on composites, bonding, guided waves, contact or damage, imaging and structural noise. The fifth meeting of the Anglo-French Research Group on "Wave propagation in non homogeneous media with a view to Non Destructive Testing", where all these results were presented, was held in Anglet, France, June 2-6, 2008.

Comment le système Foxconn – les usines chinoises qui produisent iPhone et PlayStation – expérimente et met en œuvre les pires formes d'exploitation. Les machines ressemblent à d'étranges créatures qui aspirent les matières premières, les digèrent et les recrachent sous forme de produit fini. Le processus de production automatisé simplifie les tâches des ouvriers qui n'assurent plus aucune fonction importante dans la production. Ils sont plutôt au service des machines. Nous avons perdu la valeur que nous devrions avoir en tant qu'êtres humains, et nous sommes devenus une prolongation des machines, leur appendice, leur serviteur. J'ai souvent pensé que la machine était mon seigneur et maître et que je devais lui peigner les cheveux, tel un esclave. Foxconn est le plus grand fabricant du monde dans le domaine de l'électronique. Ses villes-usines, qui font travailler plus d'un million de Chinois, produisent iPhone, Kindle et autres PlayStation pour Apple, Sony, Google, Microsoft, Amazon, etc. En 2010, elles ont été le théâtre d'une série de suicides d'ouvriers qui ont rendu publiques des conditions d'exploitation fondées sur une organisation militarisée de la production, une taylorisation extrême, l'absence totale de protection sociale et une surveillance despotique jusque dans les dortoirs où vivent les ouvriers. Ce livre propose quelques éléments d'analyse du système Foxconn à partir du portrait que fait la sociologue Jenny Chan d'une ouvrière qui a survécu à sa tentative de suicide en 2010. Complété par le témoignage de Yang, un étudiant et ouvrier de fabrication à Chongqing, il retrace également le parcours de Xu Lizhi, jeune travailleur migrant chinois à Shenzen, qui s'est suicidé en 2014 après avoir laissé des poèmes sur le travail à la chaîne, dans « L'atelier, là où ma jeunesse est restée en plan »
