Freedoms Vector: The Path to Prosperity, Opportunity and Dignity, is a book about Americaits government, its institutions, and its people. It is about a nation blessed with the finest system of governance ever devised. It is about a country that has outgrown its institutions and is in need of reconditioning. It is about a people who have been losing their faith and are waiting for a new call to greatness. Our country can recapture the spirit of 76, if we bring our better virtues and a sense of responsibility to bear upon the task. If our leaders reform their economics. If money and power do not stand in the way of freedom and democracy. If you love America, I think you will like this book. If you read this book, I think it may surprise and educate you. It may even annoy you. If it does, and you are inspired to craft a better plan for your country, I will have achieved my purpose in putting these pages between two covers.

This book deals with questions of freedom and constraint in machinery. It asks, for example, whether the smooth working of a machine will depend entirely upon the accuracy of its construction. As it answers such questions, it explores the geometrical interstices of the so-called screw systems at the.

Does a machine run well by virtue of its accuracies, or its freedoms? This work presents an exciting, diagrammatic display of the hidden geometry of freedom and constraint. It bolsters the imaginative design of robots, but applies across all fields of machinery. The figures and their captions comprise alone a self-standing story, and this connects effectively with the rigorously argued text. The seamless combination of the two volumes (1984, 1990) renders the internal cross-referencing (forward and backward within the volumes) easier to look up. The appearance of this paperback is a clear testament to the work's ongoing readership. The term screw theory occurs throughout. This relates (after Ball) to the book's philosophy; and one might equally mention kinetostatics (after Federhofer). An all-pervading, counter-intuitive fact accordingly presents itself: while, analogously, angular velocity relates to force, linear velocity relates to couple. A direct consequence of Freedom in Machinery is a more recent book by the same author. Specifically titled General Spatial Involute Gearing and published in Germany (2003), it exemplifies the many ways in which Freedom in Machinery clarifies the enigmatic field of spatial mechanism. That field continuously expands with the current, continuous thrust of ordinary engineering practice.

This book presents a range of papers by philosophers and economists who consider the definition and value of liberty; freedom in rights and equality of opportunity. Until recently freedom has played no explicit role in the conceptual framework of economists, however freedom seems to be at the heart of economics. The book provides a substantial contribution to the fruitful dialogue between the philosophy and economics in this area. Each chapter is integrated being followed by comments which explore the underlying debates. Contributors are French economists, philosophers and political scientists, as well as authors from Belgium and the Netherlands.

This book is a technical publication for students, scholars and engineers in electrical engineering, focusing on the pulse-width-modulation (PWM) technologies in power electronics area. Based on an introduction of basic PWM principles this book analyzes three major challenges for PWM on system performance: power losses, voltage/current ripple and electromagnetic interference (EMI) noise, and the lack of utilization of control freedoms in conventional PWM technologies. Then, the model of PWM's impact on system performance is introduced, with the current ripple prediction method for voltage source converter as example. With the prediction model, two major advanced PWM methods are introduced: variable switching frequency PWM and phase-shift PWM, which can reduce the power losses and EMI for the system based on the prediction model. Furthermore, the advanced PWM can be applied in advanced topologies including multilevel converters and paralleled converters. With more control variables in the advanced topologies, performance of PWM can be further improved. Also, for the special problem for common-mode noise, this book introduces modified PWM method for reduction. Especially, the paralleled inverters with advanced PWM can achieve good performance for the common-mode noise reduction. Finally, the implementation of PWM technologies in hardware is introduced in the last part.

Advances in Control Systems: Theory and Applications, Volume 5 provides information pertinent to the significant progress in the field of control and systems theory and applications. This book presents the problem of the optimal control of a system. Organized into six chapters, this volume begins with an overview of the fundamental conditions in the calculus of variations that are basic to the optimal control problem. This text then examines one of the basic problems in control and systems theory in general. Other chapters consider a number of rather basic results in optimal nonlinear filtering and describe the characteristic function of the state of vector of a nonlinear system. This book discusses as well a significant application area of control and systems theory, which is the optimal control of nuclear reactors. The final chapter deals with optimal control with bounds on the state variables. This book is a valuable resource for practicing engineers.

Non-nucleonic degrees of freedom in the nucleus must be understood in the nucleonic framework of nucleus in relation with the structure of the nucleons from which mesons are emitted to link the nucleons, and with isobars, mesonic exchange currents, and underlying conservation laws. This topical volume sheds light on these highly exciting non-nucleonic effects extracted as the result of interplay among the constituents including quarks, and on the limit of applicability of various conservation laws.
