Download or read book Visualization of Time Oriented Data written by Wolfgang Aigner and published by Springer Science & Business Media. This book was released on 2011-05-30 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time is an exceptional dimension that is common to many application domains such as medicine, engineering, business, or science. Due to the distinct characteristics of time, appropriate visual and analytical methods are required to explore and analyze them. This book starts with an introduction to visualization and historical examples of visual representations. At its core, the book presents and discusses a systematic view of the visualization of time-oriented data along three key questions: what is being visualized (data), why something is visualized (user tasks), and how it is presented (visual representation). To support visual exploration, interaction techniques and analytical methods are required that are discussed in separate chapters. A large part of this book is devoted to a structured survey of 101 different visualization techniques as a reference for scientists conducting related research as well as for practitioners seeking information on how their time-oriented data can best be visualized.
Download or read book Global Paleomagnetic Data Analysis written by Chenjian Fu and published by . This book was released on 2021 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleomagnetic Apparent Polar Wander Paths (APWPs) are the principal means of describing plate motions through most of Earth history. However, there are limitations to paleomagnetic data such as the poorly-constrained longitudes of paleo-plates and the degrading quality and density of paleomagnetic data with increasing age. Yet comparing the spatio-temporal patterns and trends of APWPs between different tectonic plates is important for testing proposed paleogeographic reconstructions of past supercontinents. Similarity between paleomagnetic APWPs of different tectonic plates could indicate the plates were once part of a supercontinent. However, there is no clearly defined quantitative approach to determine the degree of similarity between APWPs. A new similarity measuring algorithm between two APWPs, that combines three separate difference metrics that assess both spatial separation of coeval poles, and similarities in the bearing and length of coeval segments, using a weighted linear summation, is proposed. Bootstrap tests are used to determine whether the differences between coeval poles and segments are significant for the given spatial uncertainties in pole positions. An additional Fit Quality metric is used to discriminate between low difference scores caused by comparing poorly constrained paths with large spatial uncertainties from those caused by a close fit between well-constrained paths. The individual and combined metrics are demonstrated using tests on synthetic pairs of APWPs with varying degrees of spatial and geometric difference. In a test on real paleomagnetic data, these metrics can quantify the effects of correction for inclination shallowing in sedimentary rocks on Gondwana and Laurussia's 320-0 Ma APWPs. A Python package on GitHub is provided online, as open-source software, to allow automatic calculation of similarity scores. APWPs using 168 different methods are generated, and then the new APW path similarity measuring tool is applied to find the best APWP generating methods. Paleopole attributes are used to weigh their influence on mean poles, or to determine if they should be omitted for producing a 'better' mean pole. Different key attributes, that can be quantified, or their combination, are considered. In addition, when merging paleopoles to produce a smoothed mean path, choices are made not only about which data are included or excluded, but how data are combined. Moving averaging is used to combine data. The results indicate that our new Age Position Picking (APP) method (considering the whole age ranges of paleopoles) generates more reliable APWPs than the traditional Age Mean Picking (AMP) method (considering only middle points of age ranges) for making an APWP, when moving average is the core technique of the methodology. Additionally, weighting paleopoles, a traditional processing step for making a paleomagnetic APWP, is actually unnecessary. The APP method (without weighting paleopoles), which performs significantly better with modern (~120-0 Ma) paleomagnetic data than other methods, should be applied to older 'deep-time' datasets.

Download or read book The Oxford Companion to Archaeology written by Brian M. Fagan and published by Oxford University Press. This book was released on 1996-12-05 with total page 865 pages. Available in PDF, EPUB and Kindle. Book excerpt: When we think of archaeology, most of us think first of its many spectacular finds: the legendary city of Troy, Tutankhamun's golden tomb, the three-million-year-old footprints at Laetoli, the mile-high city at Machu Picchu, the cave paintings at Lascaux. But as marvelous as these discoveries are, the ultimate goal of archaeology, and of archaeologists, is something far more ambitious. Indeed, it is one of humanity's great quests: to recapture and understand our human past, across vast stretches of time, as it was lived in every corner of the globe. Now, in The Oxford Companion to Archaeology, readers have a comprehensive and authoritative overview of this fascinating discipline, in a book that is itself a rare find, a treasure of up-to-date information on virtually every aspect of the field. The range of subjects covered here is breathtaking--everything from the domestication of the camel, to Egyptian hieroglyphics, to luminescence dating, to the Mayan calendar, to Koobi Fora and Olduvai Gorge. Readers will find extensive essays that illuminate the full history of archaeology--from the discovery of Herculaneum in 1783, to the recent finding of the "Ice Man" and the ancient city of Uruk--and engaging biographies of the great figures in the field, from Gertrude Bell, Paul Emile Botta, and Louis and Mary Leakey, to V. Gordon Childe, Li Chi, Heinrich Schliemann, and Max Uhle. The Companion offers extensive coverage of the methods used in archaeological research, revealing how archaeologists find sites (remote sensing, aerial photography, ground survey), how they map excavations and report findings, and how they analyze artifacts (radiocarbon dating, dendrochronology, stratigraphy, mortuary analysis). Of course, archaeology's great subject is humanity and human culture, and there are broad essays that examine human evolution--ranging from our early primate ancestors, to Australopithecus and Cro-Magnon, to Homo Erectus and Neanderthals--and explore the many general facets of culture, from art and architecture, to arms and armor, to beer and brewing, to astronomy and religion. And perhaps most important, the contributors provide insightful coverage of human culture as it has been expressed in every region of the world. Here entries range from broad overviews, to treatments of particular themes, to discussions of peoples, societies, and particular sites. Thus, anyone interested in North America would find articles that cover the continent from the Arctic to the Eastern woodlands to the Northwest Coast, that discuss the Iroquois and Algonquian cultures, the hunters of the North American plains, and the Norse in North America, and that describe sites such as Mesa Verde, Meadowcraft Rockshelter, Serpent Mound, and Poverty Point. Likewise, the coverage of Europe runs from the Paleolithic period, to the Bronze and Iron Age, to the Post-Roman era, looks at peoples such as the Celts, the Germans, the Vikings, and the Slavs, and describes sites at Altamira, Pompeii, Stonehenge, Terra Amata, and dozens of other locales. The Companion offers equally thorough coverage of Africa, Europe, North America, Mesoamerica, South America, Asia, the Mediterranean, the Near East, Australia and the Pacific. And finally, the editors have included extensive cross-referencing and thorough indexing, enabling the reader to pursue topics of interest with ease; charts and maps providing additional information; and bibliographies after most entries directing readers to the best sources for further study. Every Oxford Companion aspires to be the definitive overview of a field of study at a particular moment of time. This superb volume is no exception. Featuring 700 articles written by hundreds of respected scholars from all over the world, The Oxford Companion to Archaeology provides authoritative, stimulating entries on everything from bog bodies, to underwater archaeology, to the Pyramids of Giza and the Valley of the Kings.

Download or read book Paleomagnetism written by Michael W. McElhinny and published by Elsevier. This book was released on 1999-10-18 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleomagnetism is the study of the fossil magnetism in rocks. It has been paramount in determining that the continents have drifted over the surface of the Earth throughout geological time. The fossil magnetism preserved in the ocean floor has demonstrated how continental drift takes place through the process of sea-floor spreading. The methods and techniques used in paleomagnetic studies of continental rocks and of the ocean floor are described and then applied to determining horizontal movements of the Earth's crust over geological time. An up-to-date review of global paleomagnetic data enables 1000 million years of Earth history to be summarized in terms of the drift of the major crustal blocks over the surface of the Earth. The first edition of McElhinny's book was heralded as a "classic and definitive text." It thoroughly discussed the theory of geomagnetism, the geologic reversals of the Earth's magnetic field, and the shifting of magnetic poles. In the 25 years since the highly successful first edition of Palaeomagnetism and Plate Tectonics (Cambridge, 1973) the many advances in the concepts, methodology, and insights into paleomagnetism warrant this new treatment. This completely updated and revised edition of Paleomagnetism: Continents and Oceans will be a welcome resource for a broad audience of earth scientists as well as laypeople curious about magnetism, paleogeography, geology, and plate tectonics. Because the book is intended for a wide audience of geologists, geophysicists, and oceanographers, it balances the mathematical and descriptive aspects of each topic. Details the theory and methodology of rock magnetism, with particular emphasis on intrepreting crustal movements from continental and oceanic measurements Outlines Earth history for the past 1000 million years, from the Rodinia super-continent through its breakup and the formation of Gondwana to the formation and breakup of Pangea and the amalgamation of Eurasia Provides a comprehensive treatment of oceanic paleomagnetism Provides a set of color pateogeographic maps covering the past 250 million years Written by two internationally recognized experts in the field
