This monograph details basic concepts and tools fundamental for the analysis and synthesis of linear systems subject to actuator saturation and developments in recent research. The authors use a state-space approach and focus on stability analysis and the synthesis of stabilizing control laws in both local and global contexts. Different methods of modeling the saturation and behavior of the nonlinear closed-loop system are given special attention. Various kinds of Lyapunov functions are considered to present different stability conditions. Results arising from uncertain systems and treating performance in the presence of saturation are given. The text proposes methods and algorithms, based on the use of linear programming and linear matrix inequalities, for computing estimates of the basin of attraction and for designing control systems accounting for the control bounds and the possibility of saturation. They can be easily implemented with mathematical software packages.
It also takes into account the expected and unexpected stresses, challenges, and life tasks that can influence development within social environments."--BOOK JACKET.
During the years between 1980 and 1999, in the midst of war and economic crisis, a record number of women were elected to national legislatures in Central American republics. Can quantitative increases in the presence of elected women in Central America produce qualitative political changes? In this detailed study, Michelle A. Saint-Germain and Cynthia Chavez Metoyer explore the reasons for this unprecedented political rise of women, and what effect it has had on the region. Focusing on Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua, the authors analyze national and regional indicators to evaluate various hypotheses concerning the reasons for women's electoral success in the region, as well as to make comparisons with findings from other world regions. They find that the election of more women depends on three things: the presence of a crisis, a pool of politically experienced women, and a culture of gender consciousness. They also compare the characteristics of Central American women legislators to women in other national legislatures around the world. The authors document how elected women have used their policy-making power to begin to change the lives of all Central Americans, women and men alike. In more than seventy-five in-depth, personal interviews, these women legislators reflect on their lives, political careers, and gender identities in their own words, providing deep insights into recent events in this region.
Throughout its history, medicine has benefited from scientific discov eries made in complementary fields such as chemistry, physics and biology. Thus, in the middle of the last century, the works of Pasteur, a chemist and biologist, by revealing the world of micro-organisms, bacteria and viruses, made it possible to control a considerable number of often fatal diseases. Guided by the work of this inspired biologist, the English surgeon, Sir Joseph Lister, developed aseptic techniques which have rendered possible the spectacular achievements of modern surgery. It is largely due to such advances that the life-expectancy of man, 50 years at the turn of the century (1900), approaches 75 years in 1981. Even today, however, in spite of this, two groups of ailments, arter iosclerosis and cancer, are responsible for 70 per cent of human deaths both in Canada and in the United States of America. The former is a degenerative process of the arterial system, the latter an uncontrolled and destructive cellular proliferation. Although several predisposing factors are known, the essential cause of these conditions is wholly unknown. As long as this ignorance of the etiology persists, all forms of therapy can be no more than palliative.
Mathematics and Multi-Ethnic Students provides detailed profiles of teachers across the nation who have implemented effective mathematics instruction for diverse student populations. In this revised edition, Yvelyne Germain-McCarthy expands upon the popular case studies and adds two new chapters to highlight the latest educational research and practices that are reflected in the case studies. A third new chapter introduces the concept of the Life-Long Learning Laboratory where courageous questions on issues such as the impact of race on student learning are discussed. Featuring useful framing tools including the Discussion with Colleagues and Commentary sections, Mathematics and Multi-Ethnic Students translates concrete instances of access and equity into generalized problem-solving methods for promoting ethnic diversity across grade levels. An important resource for pre-service and in-service educators, researchers, administrators, and policy makers, this volume highlights the work of teachers who have gone beyond mere awareness of reform recommendations in mathematics instruction. By uniting the goals of multicultural education with those of the mathematics curriculum, educators will learn to conceptualize and implement best practices for effective, equitable teaching and learning of mathematics for their students.
This book puts a spotlight on the practices of teachers across the nation who have implemented effective mathematics instruction for students of different ethnicities. Among the ethnic groups represented are African Americans, Latinos, Native Americans, Haitians, Arab Americans, and Euro-Americans.
From Simon & Schuster, Social Work Practice in Health Care is Carel Bailey Germain's comprehensive analysis of the health care system and the structural and content of social work services. An ecological perspective, Social Work Practice in Health Care, is a a classic in the field which has won praise from scholars and is gathered with the author's articles on the subject.
Originally published in 1980, this seminal work was the first to introduce an ecological perspective into social work practice. The third edition expands and deepens this perspective, further developing the basic premise that, by being situated within the people:environment interface, the social work profession is distinct from other service professions. The book presents the "what" (theories and concepts) and the "how" (practice methods) to help people with their life stressors and, simultaneously, to influence communities, organizations, and policymakers to be more responsive to them. In this edition, Gitterman and Germain examine major changes to our socioeconomic and political landscape. They restore a chapter on the history of social work practice, offering a view of the limited services for African Americans provided by settlements and charity organization societies. Building on the African American self-help and mutual aid traditions, this chapter traces the replication of a parallel social service system by African American leaders for their own communities. The chapter also addresses the impact of contemporary societal trends, including the global economy, immigration, cultural changes, and the technology revolution. In addition, it discusses current professional contexts of managed mental health care, evidence-based practice, and the professional uses of technology. A new chapter explores issues and processes embedded in assessment, practice monitoring, and practice evaluation. The volume continues to feature innovative schema for assessment and intervention with respect to stressful life transitions and traumatic events, environmental pressures, and dysfunctional interpersonal processes. Practice illustrations offer reflections of today's major social issues, such as AIDS, homelessness, and modern forms of violence.
Fully modern corporations appeared in fourteenth-century Toulouse, much earlier than previously believed Germain Sicard proves that Europe's first corporations were fourteenth-century mill companies operating in Toulouse, rather than seventeenth-century English and Dutch trading companies as commonly believed. He shows that the corporate form derives from a unique ownership contract from Medieval Europe called pariage, and a culture of strong property rights and municipal self-governance. Based on archival research, Sicard's 1952 thesis has been translated into English with an introduction that places the work in the context of new institutional economics and legal theory. It is an important contribution to research on the history and legal origins of the corporation.
Funny, touching, and inspiring! A book about really walking the Camino de Santiago! Perhaps it was the onset of middle-age or just too much diet cola, but in the Spring of 2010, Canadian boy, Randall St. Germain felt called to take on the 800 kilometer, or 500 mile Camino de Santiago pilgrimage from St. Jean Pied de Port, France to Santiago de Compostela, Spain. Seriously, what ensued was a dedication to his mother, a personal challenge, and a journey of cultural and historical enlightenment. A million footsteps, and a few pounds of gauze and tape later, he arrived in Santiago de Compostela, with a better understanding of himself - and a newfound familiarity with snoring and flatulent pilgrims! Join St. Germain on his adventure in Camino de Santiago In 20 Days, an irreverently chuckle-inducing look at one man's attempt at the famed walk as he confronts apocalyptic weather, snarling dogs, epic blisters, an exhausted body, and his greatest paranoia in life-bed bugs. Along with his humorous reflections, there is practical insight into how he successfully prepared, packed, and then walked across the entire French Way in 20 days - and in doing so, pushed far beyond his personal comfort zone. Never to be included on the final list of Pulitzer Prize nominees, or in Oprah's Book Club, Camino de Santiago in 20 Days is not your granddaddy's Camino book, either. One word of caution: Pilgrim Discretion is Advised.

Physical, safety and technological constraints suggest that control actuators can neither provide unlimited amplitude signals nor unlimited speed of reaction. The techniques described in this book are useful for industrial applications in aeronautical or space domains, and in the context of biological systems. Such methods are well suited for the development of tools that help engineers to solve analysis and synthesis problems of control systems with input and output constraints.
