Download or read book Biped Locomotion written by Miomir Vukobratovic and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here for the first time in one book is a comprehensive and systematic approach to the dynamic modeling and control of biped locomotion robots. A survey is included of various approaches to the control of biped robots, and a new approach to the control of biped systems based on a complete dynamic model is presented in detail. The stability of complete biped system is presented for the first time as a highly nonlinear dynamic system. Also included is new software for the synthesis of a dynamically stable walk for arbitrary biped systems, presented here for the first time. A survey of various realizations of biped systems and numerous numerical examples are given. The reader is given a deep insight into the entire area of biped locomotion. The book covers all relevant approaches to the subject and gives the most complete account to date of dynamic modeling, control and realizations of biped systems.

Download or read book Nonsmooth Mechanics written by Bernard Brogliato and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thank you for opening the second edition of this monograph, which is devoted to the study of a class of nonsmooth dynamical systems of the general form: ::i; = g(x,u) (0. 1) f(x, t) 2: 0 where x E JRn is the system's state vector, u E JRm is the vector of inputs, and the function f (-, . ) represents a unilateral constraint that is imposed on the state. More precisely, we shall restrict ourselves to a subclass of such systems, namely mechanical systems subject to unilateral constraints on the position, whose dynamical equations may be in a first instance written as: ii= g(q,q,u) (0. 2) f(q, t) 2: 0 where q E JRn is the vector of generalized coordinates of the system and u is an in put (or controller) that generally involves a state feedback loop, i. e. u= u(q, q, t, z), with z= Z(z, q, q, t) when the controller is a dynamic state feedback. Mechanical systems composed of rigid bodies interacting fall into this subclass. A general prop erty of systems as in (0. 1) and (0. 2) is that their solutions are nonsmooth (with respect to time): Nonsmoothness arises primarily from the occurence of impacts (or collisions, or percussions) in the dynamical behaviour, when the trajectories attain the surface f(x, t) = O. They are necessary to keep the trajectories within the subspace = {x : f(x, t) 2: O} of the system's state space.

Download or read book Social Media in Industrial China written by Xinyuan Wang and published by UCL Press. This book was released on 2016-09-13 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life outside the mobile phone is unbearable.’ Lily, 19, factory worker. Described as the biggest migration in human history, an estimated 250 million Chinese people have left their villages in recent decades to live and work in urban areas. Xinyuan Wang spent 15 months living among a community of these migrants in a small factory town in southeast China to track their use of social media. It was here she witnessed a second migration taking place: a movement from offline to online. As Wang argues, this is not simply a convenient analogy but represents the convergence of two phenomena as profound and consequential as each other, where the online world now provides a home for the migrant workers who feel otherwise ‘homeless’. Wang’s fascinating study explores the full range of preconceptions commonly held about Chinese people – their relationship with education, with family, with politics, with ‘home’ – and argues why, for this vast population, it is time to reassess what we think we know about contemporary China and the evolving role of social media.

Download or read book Unpacking IKEA written by Pauline Garvey and published by Routledge. This book was released on 2017-11-23 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first anthropological ethnography of Ikea consumption and goes to the heart of understanding the unique and at times frantic popularity of this one iconic transnational store. Based on a year of participant observation in Stockholm’s Kungens Kurva store – the largest in the world - this book places the retailer squarely within the realm of the home-building efforts of individuals in Stockholm and to a lesser degree in Dublin. Ikea, the world’s largest retailer and one of its most interesting, is the focus of intense popular fascination internationally, yet is rarely subject to in-depth anthropological inquiry. In Unpacking Ikea, Garvey explores why Ikea is never ‘just a store’ for its customers, and questions why it is described in terms of a cultural package, as everyday and classless. Using in-depth interviews with householders over several years, this ethnographic study follows the furniture from the Ikea store outwards to probe what people actually take home with them.

Download or read book Social Media in an English Village written by Daniel Miller and published by UCL Press. This book was released on 2016-02-29 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Daniel Miller spent 18 months undertaking an ethnographic study with the residents of an English village, tracking their use of the different social media platforms. Following his study, he argues that a focus on platforms such as Facebook, Twitter and Instagram does little to explain what we post on social media. Instead, the key to understanding how people in an English village use social media is to appreciate just how ‘English’ their usage has become. He introduces the ‘Goldilocks Strategy’: how villagers use social media to calibrate precise levels of interaction ensuring that each relationship is neither too cold nor too hot, but ‘just right’.

Download or read book The 15th International Conference on Biomedical Engineering written by James Goh and published by Springer Science & Business Media. This book was released on 2013-11-18 with total page 998 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the processing of the 15th ICMBE held from 4th to 7th December 2013, Singapore. Biomedical engineering is applied in most aspects of our healthcare ecosystem. From electronic health records to diagnostic tools to therapeutic, rehabilitative and regenerative treatments, the work of biomedical engineers is evident. Biomedical engineers work at the intersection of engineering, life sciences and healthcare. The engineers would use principles from applied science including mechanical, electrical, chemical and computer engineering together with physical sciences including physics, chemistry and mathematics to apply them to biology and medicine. Applying such concepts to the human body is very much the same concepts that go into building and programming a machine. The goal is to better understand, replace or fix a target system to ultimately improve the quality of healthcare. With this understanding, the conference proceedings offer a single platform for individuals and organizations working in the biomedical engineering related field to gather and network with each other in so doing create the catalyst for future development of biomedical engineering in Asia.
