Inhaltsangabe:Abstract: The visualisation of information is a broad area of study not uniquely associated with computing. Its origins can be traced back to the earliest attempts at cartography. It is, however, with the development of computing technology that the discipline has flourished. It is not simply that the technology has allowed for more detailed visual representations to be produced, it is equally the case that the wealth of data available and the understanding of its importance have accelerated the demand for its analysis. The range of modern visualisation is huge, including medical imaging, engineering simulations and geographical and meteorological analysis. Information can come in many forms the two most common to visualisation are numerical data and functional representation. This thesis investigates visualisation methods for both mathematical functions of two variables and three-dimensional data. In particular I examined techniques as contour plots and surface plots. Within the bounds of this project OpenGL turned out to be the most powerful tool regarding visualisation of information. Due to the procedural architecture of OpenGL and an ambition to learn the core architecture of Microsoft Windows®, I decided to exclusively implement this project in Win32®, for which I pay particular attention in this dissertation.

Categorization, the basic cognitive process of arranging objects into categories, is a fundamental process in human and machine intelligence and is central to investigations and research in cognitive science. Until now, categorization has been approached from singular disciplinary perspectives with little overlap or communication between the disciplines involved (Linguistics, Psychology, Philosophy, Neuroscience, Computer Science, Cognitive Anthropology). Henri Cohen and Claire Lefebvre have gathered together a stellar collection of contributors in this unique, ambitious attempt to bring together converging disciplinary and conceptual perspectives on this topic. "Categorization is a key concept across the range of cognitive sciences, including linguistics and philosophy, yet hitherto it has been hard to find accounts that go beyond the concerns of one or two individual disciplines. The Handbook of Categorization in Cognitive Science provides just the sort of interdisciplinary approach that is necessary to synthesize knowledge from the different fields and provide the basis for future innovation." Professor Bernard Comrie, Department of Linguistics, Max Planck Institute for Evolutionary Anthropology, Germany "Anyone concerned with language, semantics, or categorization will want to have this encyclopedic collection."

Folge dem Ruf der Wellen und du findest dein Glück! Als Lotte Seliger mit ihrer Mutter und ihren zwei Schwestern eine Reise nach New York antritt, ahnt sie nicht, was sie erwartet: Auf dem Rückflug muss die Maschine notlanden und die vier Seliger-Frauen sitzen an der kanadischen Ostküste fest. Lotte weiß nun nicht, ob sie es rechtzeitig zu ihrer Hochzeit nach Deutschland schaffen wird. Doch das ist noch nicht alles: Das Flughafenhotel ist ausgebucht und ausgerechnet ein mürrischer Typ namens Connor bietet Lotte und ihrer Familie Hilfe an. Lotte verliebt sich auf Anhieb in die malerische Landschaft am Atlantik und in das „Mapletree Bed & Breakfast“, wo sie unterkommen. Der Aufenthalt in Kanada könnte dank Blaubeermuffins, Strandspaziergängen und Muschelsuppe unverhofft schön werden, wenn Lotte nicht ständig von ihrer Familie auf Trab gehalten würde – und von dem schroffen Connor mit den unverschämt blauen Augen. Warum ist er ihr gegenüber bloß so unfreundlich? Als Lotte an einem stürmischen Nachmittag in Lebensgefahr gerät, ist ausgerechnet er zur Stelle ...

New research and the discovery of multiple archaeological sites predating the established age of Clovis (13,000 years ago) provide evidence that the Americas were first colonized at least one thousand to two thousand years before Clovis. These revelations indicate to researchers that the peopling of the Americas was perhaps a more complex process than previously thought. The Clovis culture remains the benchmark for chronological, technological, and adaptive comparisons in research on peopling of the Americas. In Clovis: On the Edge of a New Understanding, volume editors Ashley Smallwood and Thomas Jennings bring together the work of many researchers actively studying the Clovis complex. The contributing authors presented earlier versions of these chapters at the Clovis: Current Perspectives on Chronology, Technology, and Adaptations symposium held at the 2011 Society for American Archaeology meetings in Sacramento, California. In seventeen chapters, the researchers provide their current perspectives of the Clovis archaeological record as they address the question: What is and what is not Clovis?

Some 13,000 years ago, humans were drawn repeatedly to a small valley in what is now Central Texas, near the banks of Buttermilk Creek. These early hunter-gatherers camped, collected stone, and shaped it into a variety of tools they needed to hunt game, process food, and subsist in the Texas wilderness. Their toolkit included bifaces, blades, and deadly spear points. Where they worked, they left thousands of pieces of debris, which have allowed archaeologists to reconstruct their methods of tool production. Along with the faunal material that was also discarded in their prehistoric campsite, these stone, or lithic, artifacts afford a glimpse of human life at the end of the last ice age during an era referred to as Clovis. The area where these people roamed and camped, called the Gault site, is one of the most important Clovis sites in North America. A decade ago a team from Texas A&M University excavated a single area of the site—formally named Excavation Area 8, but informally dubbed the Lindsey Pit—which features the densest concentration of Clovis artifacts and the clearest stratigraphy at the Gault site. Some 67,000 lithic artifacts were recovered during fieldwork, along with 5,700 pieces of faunal material. In a thorough synthesis of the evidence from this prehistoric “workshop,” Michael R. Waters and his coauthors provide the technical data needed to interpret and compare this site with other sites from the same period, illuminating the story of Clovis people in the Buttermilk Creek Valley.

Roughly thirteen thousand years ago, Clovis hunters cached more than fifty projectile points, preforms, and knives at the toe of a gentle slope near present-day Elgin, Bastrop County, in central Texas. Over the next millennia, deposition buried the cache several meters below the surface. The entombed artifacts lay undisturbed until 2003. A circuitous path brought thirteen of the original thirty-seven Clovis bifaces and points through many hands before reaching the attention of Michael Waters at Texas A&M University. At the site of the original cache, Waters and coauthor Thomas A. Jennings conducted excavations, studied the geology, and dated the geological layers to reconstruct how the cache was buried. This book provides a well-illustrated, thoroughly analyzed description and discussion of the Hogeye Clovis cache, the projectile points and other artifacts from later occupations, and the geological context of the site, which has yielded evidence of multiple Paleoindian, Archaic, and Late Prehistoric occupations. The cache of tools and weapons at Hogeye, when combined with other sites, allows us to envision a snapshot of life at the end of the last Ice Age.

Around 11,000 years ago, a Paleoindian culture known to us as "Clovis" occupied much of North America. Considered to be among the continent's earliest human inhabitants, the Clovis peoples were probably nomadic hunters and gatherers whose remaining traces include camp sites and caches of goods stored for utilitarian or ritual purposes. This book offers the first comprehensive study of a little-known aspect of Clovis culture—stone blade technology. Michael Collins introduces the topic with a close look at the nature of blades and the techniques of their manufacture, followed by a discussion of the full spectrum of Clovis lithic technology and how blade production relates to the production of other stone tools. He then provides a full report of the discovery and examination of fourteen blades found in 1988 in the Keven Davis Cache in Navarro County, Texas. Collins also presents a comparative study of known and presumed Clovis blades from many sites, discusses the Clovis peoples' caching practices, and considers what lithic technology and caching behavior can add to our knowledge of Clovis lifeways. These findings will be important reading for both specialists and amateurs who are piecing together the puzzle of the peopling of the Americas, since the manufacture of blades is a trait that Clovis peoples shared with the Upper Paleolithic peoples in Europe and northern Asia.

Gregory the Great (+604) was a master of the art of exegesis. His interpretations are theologically profound, methodologically fascinating, and historically influential. Nowhere is this more clearly seen than in his exegesis of the Song of Songs. Gregory’s interpretation of this popular Old Testament book not only owes much to Christian exegetes who preceded him, such as Origen, but also profoundly influenced later Western Latin exegetes, such as Bernard of Clairvaux.This volume includes all that Gregory had to say on the Song of Songs: his Exposition on the Song of Songs, the florilegia compiled by Paterius (Gregory’s secretary) and the Venerable Bede, and, finally, William of Saint Thierry’s Excerpts from the Books of Blessed Gregory on the Song of Songs. It is now the key resource for reading and studying Gregory’s interpretation of the Song of Songs.
