Die Lautgeographie gehört zu den erfolgreichsten Gebieten der klassischen Dialektologie. Zur regionalen Variation der Intonation hingegen liegen bis heute kaum substantielle Ergebnisse vor. Einer der Gründe hierfür dürfte sein, dass für die Identifikation intonatorischer Systeme ganz andere Abstraktionsleistungen erforderlich sind als die, die wir bei der Identifikation eines Lautsystems vollziehen und teilweise bereits im Rahmen des Schrifterwerbs erlernen. Die vorliegende Studie zeigt, dass wir heute aufgrund neuerer Entwicklungen in der Intonationsforschung, insbesondere im Rahmen der Autosegmental-Metrischen Phonologie, in einer besseren Lage sind als je zuvor, um die Forschungslücke, die uns die klassische Dialektologie hinterlassen hat, zu füllen. Zu diesem Zweck werden die Intonationssysteme von sechs städtischen Regionalsprachen des Deutschen miteinander verglichen. Als Datengrundlage dienen natürlichsprachliche Korpora aus den Städten Hamburg, Berlin, Duisburg, Köln, Mannheim und Freiburg. Zu den wichtigsten Ergebnissen der Untersuchung zählt, dass die von Eduard Sievers zu Beginn des 20. Jahrhunderts angenommene melodische Zweiteilung des deutschen Sprachraums zumindest teilweise bestätigt werden kann. Die Audio-CD-ROM mit einem großen Korpus an Sprachaufnahmen bietet die Möglichkeit des Nachvollzugs aller Thesen dieser Pionierarbeit.

Phonologie, die Lehre von der lautlichen Organisation der Sprache, ist einer der zentralen Bereiche der Sprachwissenschaft. Auch das Schriftsystem, das Gegenstand der Graphematik ist, gewinnt zunehmend an Bedeutung für Forschung und Lehre. Dieser Band informiert über Form und Funktion der wichtigsten Einheiten des gesprochenen und geschriebenen Deutschen, von den Lauten und Buchstaben über Sprech- und Schreibsilben bis hin zu phonologischen und graphematischen Wörtern, phonologischen Äußerungen und graphematischen Sätzen. In zweifarbiger Gestaltung mit Definitionen, Beispielen, Grafiken und Aufgaben. – Die 2. Auflage wurde durchgängig aktualisiert und erweitert.

The intonational diversity of regional varieties provides a challenge to both traditional and autosegmental theories of intonation, which mostly derived from the study of national standard languages. The ten chapters in this book give an overview of current research covering regional varieties of English, German, Italian and Greek. While all contributions share a general autosegmental perspective, they represent different approaches and use different types of data ranging from experimental speech data to spontaneous conversational speech.

Since their first appearance in 1974, subdivision algorithms for generating surfaces of arbitrary topology have gained widespread popularity in computer graphics and are being evaluated in engineering applications. This development was complemented by ongoing efforts to develop appropriate mathematical tools for a thorough analysis, and today, many of the fascinating properties of subdivision are well understood. This book summarizes the current knowledge on the subject. It contains both meanwhile classical results as well as brand-new, unpublished material, such as a new framework for constructing C^2-algorithms. The focus of the book is on the development of a comprehensive mathematical theory, and less on algorithmic aspects. It is intended to serve researchers and engineers - both new to the beauty of the subject - as well as experts, academic teachers and graduate students or, in short, anybody who is interested in the foundations of this flourishing branch of applied geometry.

It is with greatpleasure that we present the proceedings of the 4th International Symposium on Visual Computing (ISVC 2008) in Las Vegas, Nevada. ISVC o?ers a common umbrella for the four main areas of visual computing including vision, graphics, visualization, and virtual reality. Its goal is to provide a forum for researchers, scientists, engineers and practitioners throughout the world to present their latest research ?ndings, ideas, developments and applications in the broader area of visual computing. This year,ISVC grew signi?cantly; the programconsisted of 15 oralsessions, 1 poster session, 8 special tracks, and 6 keynote presentations. The response to the call for papers was very strong; we received over 340 submissions for the main symposium from which we accepted 102 papers for oral presentation and 70 papers for poster presentation. Special track papers were solicited separately through the Organizing and Program Committees of each track. A total of 56 papers were accepted for oral presentation and 8 papers for poster presentation in the special tracks. All papers were reviewed with an emphasis on potential to contribute to the state of the art in the ?eld. Selection criteria included accuracy and originality of ideas, clarity and signi?cance of results, and presentation quality. The review process was quite rigorous, involving two to three independent blind reviews followed by several days of discussion. During the discussion period we tried to correct anomalies and errors that might have existed in the initial reviews.
