Equipping you with a real-world understanding of geography-related concepts, Hobbs' WORLD REGIONAL GEOGRAPHY, 7th Edition, introduces you to the eight world regions by providing the historical, cultural, economic, political and physical context that makes each unique, while MindTap empowers you with anywhere, anytime digital learning tools and interactive ArcGIS-powered mapping activities. The text's emphasis on the impact of human interaction on geography helps you see the relevance of the field in everyday life. The 7th edition spotlights COVID-19's capacity to change long-standing economic and migration patterns. It also delivers the most up-to-date coverage available on IPCC emissions scenarios, UN Sustainable Development Goals, the ongoing refugee crisis, Brexit, emerging geopolitical issues in the Middle East and North Africa, and much more.

Over the years, the electric power industry has been using optimization methods to help them solve the unit commitment problem. The result has been savings of tens and perhaps hundreds of millions of dollars in fuel costs. Things are changing, however. Optimization technology is improving, and the industry is undergoing radical restructuring. Consequently, the role of commitment models is changing, and the value of the improved solutions that better algorithms might yield is increasing. The dual purpose of this book is to explore the technology and needs of the next generation of computer models for aiding unit commitment decisions.Because of the unit commitment problem's size and complexity and because of the large economic benefits that could result from its improved solution, considerable attention has been devoted to algorithm development in the book. More systematic procedures based on a variety of widely researched algorithms have been proposed and tested. These techniques have included dynamic programming, branch-and-bound mixed integer programming (MIP), linear and network programming approaches, and Benders decomposition methods, among others. Recently, metaheuristic methods have been tested, such as genetic programming and simulated annealing, along with expert systems and neural networks. Because electric markets are changing rapidly, how UC models are solved and what purposes they serve need reconsideration. Hence, the book brings together people who understand the problem and people who know what improvements in algorithms are really possible. The two-fold result in The Next Generation of Electric Power Unit Commitment Models is an assessment of industry needs and new formulations and computational approaches that promise to make unit commitment models more responsive to those needs.

Cengage Learning's FUNDAMENTALS OF WORLD REGIONAL GEOGRAPHY brings course concepts to life with interactive learning, study, and exam preparation tools along with comprehensive text content for one semester/quarter courses. Whether you use a traditional printed text or all digital MindTap alternative, it's never been easier to better understand the eight world regions, including the historical, cultural, economic, political, and physical aspects that create regional unity, give them personality, and make them newsworthy.

The distinctive relationships between landscape change, habitat fragmentation, and biodiversity conservation are highlighted in this original and useful guide to the theory and practice of ecological landscape design. Using original, ecologically based landscape design principles, the text underscores current thinking in landscape management and conservation. It offers a blend of theoretical and practical information that is illustrated with case studies drawn from across the globe. Key insights by some of the world’s leading experts in landscape ecology and conservation biology make Managing and Designing Landscapes for Conservation an essential volume for anyone involved in landscape management, natural resource planning, or biodiversity conservation.
