The Flexible AC Transmission System (FACTS)--a new technology based on power electronics--offers an opportunity to enhance controllability, stability, and power transfer capability of ac transmission systems. Two pioneers in the field provide in-depth discussions on power semiconductor devices, voltage-sourced and current-sourced converters, specific FACTS controllers, and major FACTS applications in the U.S.
New insights from the science of science Facts change all the time. Smoking has gone from doctor recommended to deadly. We used to think the Earth was the center of the universe and that the brontosaurus was a real dinosaur. In short, what we know about the world is constantly changing. Samuel Arbesman shows us how knowledge in most fields evolves systematically and predictably, and how this evolution unfolds in a fascinating way that can have a powerful impact on our lives. He takes us through a wide variety of fields, including those that change quickly, over the course of a few years, or over the span of centuries.
Identifies learning disabilities; problems people may have with reading, writing, and mathematics; how to evaluate and test for learning disorders; and how to cope.

Traditionally, the concept of quality of life has been viewed through objective indicators. Beyond Facts looks at quality of life through a new lens, namely, the perceptions of millions of Latin Americans. Using an enhanced version of the recently created Gallup World Poll that incorporates Latin America-specific questions, the Inter-American Development Bank surveyed people from throughout the region and found that perceptions of quality of life are often very different from the reality. These surprising findings have enormous significance for the political economy of the region and provide a wealth of information for policymakers and development practitioners to feast upon.
Powerful Understanding explores effective ways to build social-emotional skills and help students make connections, question what they read, and reflect on their learning as they develop into stronger readers and learners. Lessons based in both strategic and critical thinking revolve around core anchor books that help integrate inquiry into everything you teach — from social responsibility, to immigration, to life cycles. This highly readable book includes a wealth of classroom examples and extensive hands-on activities designed to help students to think more deeply, learn more widely, and develop a more powerful understanding of what it means to be a responsible and compassionate person.
A student-active introduction to astronomy, emphasizing inquiry learning so students will clearly understand our universe and the scientific method. Within-text and end-of-chapter questions check understanding of concepts and require the student to think critically through astronomy-based problems. 'Nature of Science' and 'Detectives on the Case' sections in each chapter encourage students to take on the role of a scientist and so develop an understanding of how scientific progress is made, leading students through a chain of arguments of forming and testing hypotheses, in the context of specific astronomical topics. By focusing on key topics, the student is able to develop a deeper understanding of the core areas of astronomy. Math is used to make intuitive points and kept simple by using a two-track system to first describe the logic of the calculation followed by a more detailed example. Simple illustrations support the text and step students through concepts visually.
