The International Polar Years (IPY) and the International Geophysical Year (IGY) represented a remarkable international collaborative scientific effort that was focused on, but not limited to, understanding the poles. These efforts demonstrated the consistency of scientific goals and methods across political boundaries. At the same time, they increased both knowledge and international tensions. This collection of essays explores the various scientific expeditions of the IPYs and the IGY, bringing together contributions from a variety of specialists. They offer overviews of the scientific progress achieved in each case, as well as the political, economic, and military factors that influenced these undertakings. Collectively, they provide new insights into the professionalization of scientific disciplines, national styles of scientific investigation and collaboration, scientific patronage, and the emergence of the global geosciences. .
Flexible mechanical systems experience undesirable vibration in response to environmental and operational forces. The very existence of vibrations can limit the accuracy of sensitive instruments or cause significant errors in applications where high-precision positioning is essential so in many situations control of vibrations is a necessity. Piezoelectric transducers have been used in countless applications as sensors, actuators, or both. When traditional passive vibration control techniques fail to meet requirements, piezoelectric transducers in conjunction with feedback controllers can be used effectively to suppress vibrations. Piezoelectric Transducers for Vibration Control and Damping presents recent developments in vibration control systems that employ embedded piezoelectric sensors and actuators. In particular, it covers various ways in which active vibration control systems can be designed for piezoelectric laminated structures, paying distinct attention to how such control systems can be implemented in real time. The text contains numerous examples and experimental results obtained from laboratory-scale apparatus, with details of how similar setups can be built. Features and topics:
An essential text and reference for graduates, researchers, and professionals working in mechanical engineering, aerospace engineering and mechatronics disciplines, this book will be a specially useful resource for scientists and engineers engaged in vibration control research.
Covering the complete design cycle of nanopositioning systems, this is the first comprehensive text on the topic. The book first introduces concepts associated with nanopositioning stages and outlines their application in such tasks as scanning probe microscopy, nanofabrication, data storage, cell surgery and precision optics. Piezoelectric transducers, employed ubiquitously in nanopositioning applications are then discussed in detail including practical considerations and constraints on transducer response. The reader is then given an overview of the types of nanopositioner before the text turns to the in-depth coverage of mechanical design including flexures, materials, manufacturing techniques, and electronics. This process is illustrated by the example of a high-speed serial-kinematic nanopositioner. Position sensors are then catalogued and described and the text then focuses on control. Several forms of control are treated: shunt control, feedback control, force feedback control and feedforward control (including an appreciation of iterative learning control). Performance issues are given importance as are problems limiting that performance such as hysteresis and noise which arise in the treatment of control and are then given chapter-length attention in their own right. The reader also learns about cost functions and other issues involved in command shaping, charge drives and electrical considerations. All concepts are demonstrated experimentally including by direct application to atomic force microscope imaging. Design, Modeling and Control of Nanopositioning Systems will be of interest to researchers in mechatronics generally and in control applied to atomic force microscopy and other nanopositioning applications. Microscope developers and mechanical designers of nanopositioning devices will find the text essential reading.
Fundamental to the study of any mathematical structure is an understanding of its symmetries. In the class of Banach spaces, this leads naturally to a study of isometries-the linear transformations that preserve distances. In his foundational treatise, Banach showed that every linear isometry on the space of continuous functions on a compact metric space must transform a continuous function x into a continuous function y satisfying y(t) = h(t)x(p(t)), where p is a homeomorphism and |h| is identically one.
In recent years, new paradigms have emerged to replace-or augment-the traditional, mathematically based approaches to optimization. The most powerful of these are genetic algorithms (GA), inspired by natural selection, and genetic programming, an extension of GAs based on the optimization of symbolic codes. Robust Control Systems with Genetic Algorithms builds a bridge between genetic algorithms and the design of robust control systems. After laying a foundation in the basics of GAs and genetic programming, it demonstrates the power of these new tools for developing optimal robust controllers for linear control systems, optimal disturbance rejection controllers, and predictive and variable structure control. It also explores the application of hybrid approaches: how to enhance genetic algorithms and programming with fuzzy logic to design intelligent control systems. The authors consider a variety of applications, such as the optimal control of robotic manipulators, flexible links and jet engines, and illustrate a multi-objective, genetic algorithm approach to the design of robust controllers with a gasification plant case study. The authors are all masters in the field and clearly show the effectiveness of GA techniques. Their presentation is your first opportunity to fully explore this cutting-edge approach to robust optimal control system design and exploit its methods for your own applications.
Fundamental to the study of any mathematical structure is an understanding of its symmetries. In the class of Banach spaces, this leads naturally to a study of isometries-the linear transformations that preserve distances. In his foundational treatise, Banach showed that every linear isometry on the space of continuous functions on a compact metric space must transform a continuous function x into a continuous function y satisfying y(t) = h(t)x(p(t)), where p is a homeomorphism and |h| is identically one. Isometries on Banach Spaces: Function Spaces is the first of two planned volumes that survey investigations of Banach-space isometries. This volume emphasizes the characterization of isometries and focuses on establishing the type of explicit, canonical form given above in a variety of settings. After an introductory discussion of isometries in general, four chapters are devoted to describing the isometries on classical function spaces. The final chapter explores isometries on Banach algebras. This treatment provides a clear account of historically important results, exposes the principal methods of attack, and includes some results that are more recent and some that are lesser known. Unique in its focus, this book will prove useful for experts as well as beginners in the field and for those who simply want to acquaint themselves with this area of Banach space theory.
Did you ever wonder why self-improvement strategies dealing with change and success make things seem so reasonable? Could it be that what makes all these mantras and pop books so appealing on a mass scale is the same thing that keeps them from working. They all "make sense." But are all the things that make sense TRUE? Dr. Fleming takes you deep within the mind of a psychologist and leadership consultant, letting you in on the secrets of the half-truth-the clever way we convince ourselves we are changing bad habits, leading a company to profitability, or even rising personally to the highest level of thinking about ultimate reality. Utilizing a questioning process that turns half-truths over to find the denied part of reality in us all, Dr. Fleming paves a way to understanding and change that no simple "7 Tips or Tools" book could possibly provide.
This volume presents contemporary evidence scientific, archaeological, botanical, textual, and historical for major revisions in our understanding of winemaking in antiquity. Among the subjects covered are the domestication of the Vinifera grape, the wine trade, the iconography of ancient wine, and the analytical and archaeological challenges posed by ancient wines. The essayists argue that wine existed as long ago as 3500 BC, almost half a millennium earlier than experts believed. Discover named these findings among the most important in 1991. Featuring the work of 23 internationally known scholars and writers, the book offers the first wide ranging treatment of wine in the early history of western Asia and the Mediterranean. Comprehensive and accessible while providing full documentation, it is sure to serve as a catalyst for future research.
The community and technical college mission requires offering relevant Career and Technical Education (CTE) programs. Board policies are plentiful for creating new programs in alignment with workforce needs. However, few districts have robust policies in place to appropriately discontinue or replace CTE programs. This book identifies successful CTE program discontinuance including how people feel about the process and the impact of institutional culture. The interviews and policy analysis conducted provide best practices to effectively and appropriately discontinue CTE programs. Eleven practical recommendations are outlined to help community and technical colleges in establishing program discontinuance processes which strategically and effectively discontinue CTE programs while making optimal use of limited fiscal and human resources. This book provides readers with information on career and technical education, appropriate strategies to manage the constant churning of CTE programs, college governance, and academic discontinuance policies.
The death of a child has a tremendous and overwhelming impact on parents and siblings, completely altering the psychological landscape of the family. In the aftermath of such a tragedy, parents face the challenge of not only dealing with their own grief, but also that of their surviving children. How can someone attempt to cease parenting a deceased child while maintaining this role with his/her other children? Is it possible for a mother or father to effectively deal with feelings of grief and loss while simultaneously helping their surviving children? Parenting After the Death of a Child: A Practitioner's Guide addresses this complex and daunting dilemma. Following on the heels of a qualitative research study that involved interviewing bereaved parents, both fathers and mothers, Buckle and Fleming have put together several different stories of loss and recovery to create an invaluable resource for clinicians, students, and grieving parents. The authors present the experience of losing a child and its subsequent impact on a family in a novel and effective way, demonstrating the strength and importance of their book for the counseling field.

A continuation of the authors' previous book, Isometries on Banach Spaces: Vector-valued Function Spaces and Operator Spaces, Volume Two covers much of the work that has been done on characterizing isometries on various Banach spaces. Picking up where the first volume left off, the book begins with a chapter on the Banach-Stone property. The authors consider the case where the isometry is from "C"0("Q," "X") to" C"0("K," "Y") so that the property involves pairs ("X," "Y") of spaces. The next chapter examines spaces "X" for which the isometries on "LP"("μ," "X") can be described as a generalization of the form given by Lamperti in the scalar case. The book then studies isometries on direct sums of Banach and Hilbert spaces, isometries on spaces of matrices with a variety of norms, and isometrieson Schatten classes. It subsequently highlights spaces on which the group of isometries is maximal or minimal. The final chapter addresses more peripheral topics, such as adjoint abelian operators and spectral isometries. Essentially self-contained, this reference explores a fundamental aspect of Banach space theory. Suitable for both experts and newcomers to the field, it offers many references to provide solid coverage of the literature on isometries.

Parallel Processing in Digital Control is a volume to be published in the new Advances in Industrial Control series, edited by Professor M.J. Grimble and Dr. M.A. Johnson of the Industrial Control Unit, University of Strathclyde. The growing complexity of digital control systems in such areas as robotics, flight control and engine control has created a demand for faster and more reliable systems. This book examines how parallel processing can satisfy these requirements. Following a survey of parallel computer architectures, MIMD (Multiple Instruction Multiple Data) machines are identified as suitable systems for digital control problems, which are characterised by a mixture of regular and irregular algorithmic tasks. An example of a typical MIMD architecture, suitable for real-time control, (the Inmos Transputer) is introduced together with its associated parallel programming language (Occam). The key problem in implementing parallel software is associated with mapping parallel tasks onto physical processors. In this book a variety of schemes are described and assessed to help illustrate potential areas of difficulty for the real-time control software engineer. Solutions are proposed and tested on a flight control case study example. Recognising the widespread acceptance of MATLAB and its derivatives for computer aided control system design, this book demonstrates how mapping strategies can be realised in this environment and integrated with a transputer development system for on-line performance evaluation. A case study example demonstrates the power of this approach and important issues are highlighted. Readers will experience the advantages of parallel processing in digital control while being made aware of the key factors to be considered in the development of an effective solution. Practising control engineers and graduate/post-graduate students will find the book of particular interest and benefit.
"The International Polar Years and the International Geophysical Year represented a remarkable international collaborative scientific effort that was focused on, but not limited to, understanding the Earth's poles. This groundbreaking collection redresses the surprising failure of historians to explore beyond even a cursory manner the richness of the IPYs and IGY as sites of historical and scientific study. In doing so, it illuminates critical aspects of the last 150 years of international scientific endeavour"--

This book is intended primarily for the doctor who is confronted with an electro cardiogram and who wishes to make his own interpretation rather than to rely entirely upon the report of a specialist. The clinical use of the electrocardiogram is the sole concern here and no attempt is made to describe electrophysiology. It is hoped that by beginning with a description of the P wave and its abnormalities the reader will gain confidence and the desire to continue to subsequent sections as he realizes the simplicity of the approach. In a further attempt towards clarity and ease of reading, the text is liberally interspersed with line drawings, all originated by the author, and at the end of each section electro cardiograms are provided, illustrating the abnormalities which have been described. Interest in the electrocardiogram has now spread from the cardiologist to a wide variety of hospital staff, including medical students, house officers, intensive care and coronary care nurses, and anaesthetists. Many general practitioners now record their own electro cardiograms and most have outpatient access to the electrocardiography department of their local hospitals. This book will provide a useful basis for their reading of the electrocardiogram and I hope convince them that its interpretation is well within their capabilities." |
