Book Description
This monograph provides readers with tools for the analysis, and control of systems with fewer control inputs than degrees of freedom to be controlled, i.e., underactuated systems. The text deals with the consequences of a lack of a general theory that would allow methodical treatment of such systems and the ad hoc approach to control design that often results, imposing a level of organization whenever the latter is lacking. The authors take as their starting point the construction of a graphical characterization or control flow diagram reflecting the transmission of generalized forces through the degrees of freedom. Underactuated systems are classified according to the three main structures by which this is found to happen—chain, tree, and isolated vertex—and control design procedures proposed. The procedure is applied to several well-known examples of underactuated systems: acrobot; pendubot; Tora system; ball and beam; inertia wheel; and robotic arm with elastic joint. The text is illustrated with MATLABsup®/sup/Simulink® simulations that demonstrate the effectiveness of the methods detailed./ppReaders interested in aircraft, vehicle control or various forms of walking robot will be able to learn from iUnderactuated Mechanical Systems

Book Description
Built around the concept of linguistic and cultural plurality, this book defines language as an instrument of action and symbolic power. Plurality is conceived here as : a complex array of voices, perspectives and approaches that seeks to preserve the complexity of the multilingual and multicultural enterprise, including language learning and teaching ; a coherent system of relationships among various languages, research traditions and research sites that informs qualitative methods of inquiry into multilingualism and its uses in everyday life ; a view of language as structured sociohistorical object, observable from several simultaneous spatiotemporal standpoints, such as that of daily interactions or that which sustains the symbolic power of institutions. This book is addressed to teacher trainers, young researchers, decision makers, teachers concerned with the role of languages in the evolution of societies and educational systems. It aims to elicit discussion by articulating practices, field observations and analyses based on a multidisciplinary conceptual framework.

Book Description
Apply Sliding Mode Theory to Solve Control Problems Interest in SMC has grown rapidly since the first edition of this book was published. This second edition includes new results that have been achieved in SMC throughout the past decade relating to both control design methodology and applications. In that time, Sliding Mode Control (SMC) has continued to gain increasing importance as a universal design tool for the robust control of linear and nonlinear electro-mechanical systems. Its strengths result from its simple, flexible, and highly cost-effective approach to design and implementation. Most importantly, SMC promotes inherent order reduction and allows for the direct incorporation of robustness against system uncertainties and disturbances. These qualities lead to dramatic improvements in stability and help enable the design of high-performance control systems at low cost. Written by three of the most respected experts in the field, including one of its originators, this updated edition of Sliding Mode Control in Electro-Mechanical Systems reflects developments in the field over the past decade. It builds on the solid fundamentals presented in the first edition to promote a deeper understanding of the conventional SMC methodology, and it examines new design principles in order to broaden the application potential of SMC. SMC is particularly useful for the design of electromechanical systems because of its discontinuous structure. In fact, where the hardware of many electromechanical systems (such as electric motors) prescribes discontinuous inputs, SMC becomes the natural choice for direct implementation. This book provides a unique combination of theory, implementation issues, and examples of real-life applications reflective of the authors’ own industry-leading work in the development of robotics, automobiles, and other technological breakthroughs.

Book Description
France is a Pacific power, with three territories, a military presence, and extensive investments. Once seen by many as a colonial interloper in the South Pacific, by the early 2000s, after it ended nuclear testing in French Polynesia and negotiated transitional Accords responding to independence demands in New Caledonia, France seems to have become generally accepted as a regional partner, even if its efforts concentrate on its own territories rather than the independent island states. But Frances future in the region has yet to be secured. By 2014 it is to have handed over a set of agreed autonomies to the New Caledonian government, before an independence referendum process begins. Past experience suggests that a final resolution of the status of New Caledonia will be divisive and could lead once again to violent confrontations. In French Polynesia, calls continue for independence and for treatment under UN decolonisation procedures, which France opposes. Other island leaders are watching, so far putting faith in the Noumea Accord, but wary of the final stages. The issues and possible solutions are more complex than the French Pacific island population of 515,000 would suggest. Combining historical background with political and economic analysis, this comprehensive study offers vital insight into the intricate history -- and problematic future -- of several of Australias key neighbours in the Pacific and to the priorities and options of the European country that still rules them. It is aimed at policy-makers, scholars, journalists, businesspeople, and others who want to familiarise themselves with the issues as Frances role in the region is redefined in the years to come.

Book Description
It is my ambition in writing this book to bring tribology to the study of control of machines with friction. Tribology, from the greek for study of rubbing, is the discipline that concerns itself with friction, wear and lubrication. Tribology spans a great range of disciplines, from surface physics to lubrication chemistry and engineering, and comprises investigators in diverse specialities. The English language tribology literature now grows at a rate of some 700 articles per year. But for all of this activity, in the three years that I have been concerned with the control of machines with friction, I have but once met a fellow controls engineer who was aware that the field existed, this including many who were concerned with friction. In this vein I must confess that, before undertaking these investigations, I too was unaware that an active discipline of friction existed. The experience stands out as a mark of the specialization of our time. Within tribology, experimental and theoretical understanding of friction in lubricated machines is well developed. The controls engineer's interest is in dynamics, which is not the central interest of the tribologist. The tribologist is more often concerned with wear, with respect to which there has been enormous progress - witness the many mechanisms which we buy today that are lubricated once only, and that at the factory. Though a secondary interest, frictional dynamics are note forgotten by tribology.
