The quadtree and octree are hierarchical data structures used to represent spatial data. They are based on the principle of recursive decomposition (similar to divide and con- conquer methods [Aho74]). This book focuses on the use of quadtree and octree representations of region data (in two and three dimensions, respectively) in applications in computer graphics, image processing, and geographic information systems (Gis), as well as computer vision, robotics, pattern recognition, solid modeling, and other areas. For a comprehensive treatment of related hierarchical representations of spatial data including points, lines, rectangles, regions, and volumes, see [Same90a]. To many people, the terms quadtree and octree have taken on a generic meaning synonymous with the term hierarchical data structure. Hierarchical data structures are useful because of their ability to focus on the interesting subsets of the data. This focusing results in an efficient representation and in improved execution times. Thus they are particularly convenient for performing set operations. Many of the operations described can often be performed as efficiently, or more so, with other data structures. Nevertheless, hierarchical data structures are attractive because of their conceptual clarity and ease of implementation. In addition, the use of some of them provides a spatial index. This is very useful in applications involving spatial databases.

What are the common forms of identity theft? Who are the most likely targets? What is law enforcement doing to counter a crime perpetrated not only by petty thieves and sophisticated con artists, but by terrorists, money-launderers, and those involved in human trafficking, drug trafficking, and illegal immigration? Identity Theft: A Reference Handbook examines these questions and more. With the 1998 Identity Theft and Assumption Deterrence Act as its starting point, this informative volume begins by explaining the federal, state, and global definitions of identity theft and how the lack of a standardized approach masks the true pervasiveness of the problem. In addition to addressing the crime's perpetrators, methods, and victims, the book also looks at what individuals, businesses, and the government are doing—and should consider doing—to curb the growth of this crime.

Brian Hodgson lived in Nepal from 1820 to 1843 during which time he wrote and publisged extensively on Nepalese culture, religion, natural history, architecture, ethnography and linguistics. Contributors from leading historians of Nepal and South Asia and from specialists in Buddhist studies, art history, linguistics, ornithology and ethnography, critically examine Hodgson's life and achievement within the context of his contribution to scholarship. Many of the drawings photographed for this book have not previously been published.

This book was written to present a general survey of the prehistory of Denmark as it has emergedafter the past decade of research. Up to the 1960s Danish archaeology was dominated by a handful of distinguished scholars: Sophus Müller, Johannes Brøndsted, Gudmund Hatt, P.V. Glob,and C.J.Becker. Moreover the discipline was strongly influenced by conti nental modes of thought, and the chronological problems were still the main focus of research. However, in Denmark as in other European countries, the 1960s became a period of change. A wave of new theories did away with the old diffusionistic framework. Many scholars spoke of a crisis in the profession. But as elsewhere in the west, the 1960s also marked the beginning of a rich productivity in the field, and today we can speak of at least three contrasting theoretical perspectives in Danish archaeology: positivist, marxist and structuralist. Each one of themhasbeen able to open up fruitful perspectives for future research. These changes first developed afterthe publication of the last major survey of Danish archaeology to be translated for readers outside Denmark, Johannes Brøndsted’s Nordische Vorzeit from 1960–3. It therefore seemed quite clear that both students and teachers in other countries would have need of a general introduction to theperspectives recently opened in Danish archaeology. It is this need which the present book see ks to meet. To be sure, many of the conclusions are preliminary, because detailed, systematic andup-todate studies are still required in many fields. Despite this lack, I have written the present boo k in the hope of providing a synthesis of the 10,000 years of Danish prehistory up to theearlystate formation of the Viking period. This wo rk could not have been written without theinspiration of many discussions with colleag ues in Denmark and abroad, too numerous to be me ntioned here. However, I owe special thanks to Professor Olaf Olsen, State Antiquary and Director of the National Museum of Denmark, who in 1975 encouraged me to write this book; to Professor J. Desmond Clark, University of California, Berkeley, who extended his generous hospitality to me during a stay in Berkeley in 1980; to Professor John Coles, University of Cambridge, who willingly offered advice in the preparation of this English edition; and finally to the Danish Research Council for the Humanities, which supported this project financially. I also wish to thank my wife, Barbara Bluestone, who did the translation and without whose endless patience, support and linguistic help this work could not have been completed.
