Book Description
This book introduces key modulation and predistortion techniques for approaching power and spectrum-efficient transmission for wireless communication systems. The book presents a combination of theoretical principles, practical implementations, and actual tests. It focuses on power and spectrally efficient modulation and transmission techniques in the portable wireless communication systems, and introduces currently developed and designed RF transceivers in the latest wireless markets. Most materials, design examples, and design strategies used are based on the author’s two decades of work in the digital communication fields, especially in the areas of the digital modulations, demodulations, digital signal processing, and linearization of power amplifiers. The applications of these practical products and equipment cover the satellite communications on earth station systems, microwave communication systems, 2G GSM and 3G WCDMA mobile communication systems, and 802.11 WLAN systems.>

Book Description
Democratic transitions have occurred in many countries in various regions across the globe, such as Southern Europe, Latin America, Africa, East and Southeast Asia, Eastern Europe and the Middle East, and these nations have undergone simuntaneously political, economic and social transformations. Yet, the patterns and characteristics of transitions have varied significantly, and different modes of transition have resulted in different outcomes. This book offers cross-national comparisons of democratic transition since the turn of the twentieth century and asks what makes democracies succeed or fail. In doing so it explores the influence the mode of transition has on the longevity or durability of the democracy, by theoretically examining and quantitatively testing this relationship. The authors argue that the mode of transition directly impacts the success and failure of democracy, and suggest that cooperative transitions, where opposition groups work together with incumbent elites to peacefully transition the state, result in democracies that last longer and are associated with higher measures of democratic quality. Based on a cross-national dataset of all democratic transitioning states since 1900, this book will be of great interest to students and scholars of international politics, comparative politics and democracy, and democratization studies.

Book Description
This volume, the result of the second annual Summer Institute sponsored by the Family Research Consortium, focuses on family transitions--both normative and non-normative. The subject of family transitions has been a central concern of the consortium largely because studies of families in motion help to highlight mechanisms leading to adaptation and dysfunction. This text represents a collective effort to understand the techniques individuals and families employ to adapt to the pressing issues they encounter along their life course.

Book Description
Transitions and Social Change: The Early Lives of American Men deals with the timing and synchronization of transition events that signify the passage of American males from adolescence to adulthood. The book is divided into four parts. Part I is an introduction to the study and its data and methods. This part also deals with the passage to adulthood, education, work, and adolescence. Part II covers the intercohort differences in the transition to adulthood. Part III studies the effects of social background differentials such as social class background, the size of the community, and ethnic ancestry to the transition to adulthood. Part IV talks about the possible consequences of early life-course transition behavior, transition to adulthood and marital stability, and social change and the transition to adulthood. The text is recommended for anthropologists, sociologists, psychologists, and any experts in the field who wish to know more about the transition of American adolescent males into adulthood, the factors that affect it, and its effects.

Book Description
This book explains why the fundamental structures of 20th century American healthcare have failed to keep up with American industry in terms of quality and cost. It describes how this has led to the introduction of industrial mass production concepts in American healthcare, such as Lean and Six Sigma, and how the resulting industrialization breaks

Book Description
Physics at Surfaces is a unique graduate-level introduction to the physics and chemical physics of solid surfaces, and atoms and molecules that interact with solid surfaces. A subject of keen scientific inquiry since the last century, surface physics emerged as an independent discipline only in the late 1960s as a result of the development of ultra-high vacuum technology and high speed digital computers. With these tools, reliable experimental measurements and theoretical calculations could at last be compared. Progress in the last decade has been truly striking. This volume provides a synthesis of the entire field of surface physics from the perspective of a modern condensed matter physicist with a healthy interest in chemical physics. The exposition intertwines experiment and theory whenever possible, although there is little detailed discussion of technique. This much-needed text will be invaluable to graduate students and researchers in condensed matter physics, physical chemistry and materials science working in, or taking graduate courses in, surface science.

Book Description
Determination of Organic Structures by Physical Methods, Volume 3 is a seven-chapter text that describes the refinements of some established physical methods for organic structure determination. Each chapter of this book examines specific physical method, including photoelectron spectroscopy, X-ray diffraction, optical rotary dispersion, circular dichroism, mass spectrometry, and electron spin resonance and NMR spectroscopies. The historical developments, instrumentation, and applications to organic chemistry of these methods are discussed. This work will be of value to organic and analytical chemists and researchers.

Book Description
The end of the Pleistocene era brought dramatic environmental changes to small bands of humans living in North America: changes that affected subsistence, mobility, demography, technology, and social relations. The transition they made from Paleoindian (Pleistocene) to Archaic (Early Holocene) societies represents the first major cultural shift that took place solely in the Americas. This event—which manifested in ways and at times much more varied than often supposed—set the stage for the unique developments of behavioral complexity that distinguish later Native American prehistoric societies. Using localized studies and broad regional syntheses, the contributors to this volume demonstrate the diversity of adaptations to the dynamic and changing environmental and cultural landscapes that occurred between the Pleistocene and early portion of the Holocene. The authors' research areas range from Northern Mexico to Alaska and across the continent to the American Northeast, synthesizing the copious available evidence from well-known and recent excavations.With its methodologically and geographically diverse approach, From the Pleistocene to the Holocene: Human Organization and Cultural Transformations in Prehistoric North America provides an overview of the present state of knowledge regarding this crucial transformative period in Native North America. It offers a large-scale synthesis of human adaptation, reflects the range of ideas and concepts in current archaeological theoretical approaches, and acts as a springboard for future explanations and models of prehistoric change.
