Cscl: Theory and Practice of An Emerging Paradigm
by Timothy KoschmannThis book, about a newly emerging area of research in instructional technology, has as its title the acronym "CSCL." Initially, CSCL was chosen as an acronym for Computer-Supported Collaborative Learning. However, some would argue that "collaborative" is often not a descriptive term for what learners do in instructional settings; further, as the field develops, the technology used to support collaboration may not always involve computers, at least not in the direct ways they have been used to support instruction in the past. To avoid getting bogged down in this terminological debate, this book uses CSCL as a designation in its own right, leaving open to interpretation precisely what words it stands for. The authors talk a great deal about the theory underlying their work. In part, this is because that is what they were asked to do, but it is also an indication of the state of the field. In an established paradigm in which the theories and methods are well agreed upon, such discussion is less central. CSCL, however, has not yet reached the stage of "normal" science. There is much to be worked out yet. This book is offered with the hope that it will help to define a direction for future work in this field. The chapters appear in alphabetical order (except for the introductory chapter and the afterword) -- not for lack of a better way to organize the chapters, but rather because the organizational possibilities are too numerous and this order does not privilege one over another. By not imposing a topical organizing structure on this collection, it is hoped that readers will feel freer to explore the chapters in a way that best suits their needs.

Dam Breach Modeling Technology (Water Science and Technology Library #17)
by V.P. SinghDams are constructed for economic development, and their construction involves large investments of money, and natural and human resources. Of the various types of dams constructed around the globe, earth dams are the most common type and constitute the vast majority of dams. When adam fails, it culminates in the sudden release of artificially stored water which, in turn, becomes a potential menace to virtually everything downstream. The dam failure may result in loss of life and property. In recent years, instances of dam failure in the world have been too many, and the resulting loss too high. As a result, dam safety pro grams have been developed in most countries of the world since the beginning of the nineteenth eighties. · Earth dams are more susceptible to failure than other types. The cause of failure is often either overtopping or piping. The modeling of dam breaching due to either or both of these causes is of fundamental importance to development of dam-safety programs. This book is, therefore, an attempt to present some aspects of earth-dam breach modeling technology. It is hoped that others will be stimulated to write more comprehensive texts on this subject of growing interest and importance. The book is divided into eight chapters. The first chapter is introductory and discusses some aspects of dams and dam failures in the world.

Data Book on Mechanical Properties of Living Cells, Tissues, and Organs
by Hiroyuki Abe Kozaburo Hayashi Masaaki SatoA research project entitled Biomechanics of Structure and Function of Living Cells, Tissues, and Organs was launched in Japan in 1992. This data book presents the original, up-to-date information resulting from the research project, supplemented by some of the important basic data published previously. The aim of collecting the information is to offer accurate and useful data on the mechanical properties of living materials to biomechanical scientists, biomedical engineers, medical scientists, and clinicians. The data are presented in graphs and tables (one type of data per page) arranged in an easily accessible manner, along with details of the origin of the material and the experimental method. Together with its two companion volumes, Biomechanics: Functional Adaptation and Remodeling and Computational Biomechanics, the Data Book on Mechanical Properties of Living Cells, Tissues, and Organs is a timely and valuable contribution to the rapidly growing field of biomechanics.
Data Communications and their Performance: Proceedings of the Sixth IFIP WG6.3 Conference on Performance of Computer Networks, Istanbul, Turkey, 1995 (IFIP Advances in Information and Communication Technology)
by Serge Fdida Raif O. OnvuralThis is the sixth conference in the series which started in 1981 in Paris, followed by conferences held in Zurich (1984), Rio de Janeirio (1987), Barcelona (1991), and Raleigh (1993). The main objective of this IFIP conference series is to provide a platform for the exchange of recent and original contributions in communications systems in the areas of performance analysis, architectures, and applications. There are many exiciting trends and developments in the communications industry, several of which are related to advances in Asynchronous Transfer Mode·(ATM), multimedia services, and high speed protocols. It is commonly believed in the communications industry that ATM represents the next generation of networking. Yet, there are a number of issues that has been worked on in various standards bodies, government and industry research and development labs, and universities towards enabling high speed networks in general and ATM networks in particular. Reflecting these trends, the technical program of the Sixth IFIP W.G. 6.3 Conference on Performance of Computer Networks consists of papers addressing a wide range of technical challenges and proposing various state of the art solutions to a subset of them. The program includes 25 papers selected by the program committee out of 57 papers submitted.
Datenbanken und SQL: Eine praxisorientierte Einführung (Informatik & Praxis)
by Edwin SchickerDatenbanken entstanden ab etwa 1960 aus der Notwendigkeit, die logischen auf die immer größer werdenden Datenmengen zu vereinfachen und Zugriffe zu normieren. Wurden diese Datenbanken über mehr als zwei Jahrzehnte hin weg ausschließlich auf Großrechnern eingesetzt, so haben sie inzwischen ihren Siegeszug auch auf Kleinrechnern angetreten. Ermöglicht wurde dies aus dreierlei Gründen: erstens durch die enorm gestiegene Rechnerleistung der letzten Jahre, zweitens durch die Verwendung relationaler Datenbanken und drittens durch die Einführung grafischer Oberflächen. Die Anfang der 70er Jahre entwickelten relationalen Datenbanken ermögli chen eine einfache Erstellung und Programmierung. Grafische Oberflächen unterstützen den Anwender und Datenbankdesigner dank einer leichten Benut zerführung und anschaulichen Musterbeispielen, so daß auch dem interessier ten Laien diese Form der Datenhaltung mit all ihren Möglichkeiten offen steht. Der Laie sei aber davor gewarnt, größere Datenbanken ohne theoretische Grundkenntnisse selbst zu erstellen. Denn hier leitet sich der Datenbankent wurf in der Regel nicht mehr direkt aus der AufgabensteIlung ab. Doch nur ein guter Entwurf garantiert übersichtliche und optimale Zugriffe und ermöglicht je nach Bedarf Ergänzungen und Erweiterungen der Datenbank. Auch wird nur dadurch die Konsistenz und Integrität der Datenbank ermöglicht, so daß feh lerhafte, widersprüchliche und nicht mehr zugreifbare Datenbestände verhin dert werden. Grundlagen zu Datenbankentwurf und -programmierung sollten für den Datenbankprogrammierer daher selbstverständlich sein. Dieses Buch entstand aus mehreren Vorlesungen zu Datenbanken, die ich an der Fachhochschule Regensburg für Informatiker gelesen habe. Doch ich will auch den Nicht-Informatiker und interessierten Laien gezielt ansprechen. Dazu wird mit zahlreichen Beispielen die Theorie direkt in die Praxis umgesetzt.

Dem Denken abgeschaut: Neuronale Netze im praktischen Einsatz (Facetten)
by Heike SpeckmannSind neuronale Netze das neue Allheilmittel für Anwenderprobleme, oder sind sie nur des "Kaisers neue Kleider", d.h. leisten sie nur das gleiche wie klassische Statistikverfahren unter einem neuen Decknamen? Dieser Fragestellung soll hier nachgegangen werden, indem ein spezielles, recht leistungsfähiges neuronales Netz, Kohonens selbstorganisierende Karte, betrachtet wird. Verschiedenste Anwender berichten ihre Motivation zur Nutzung dieses Netzes und Erfahrungen mit der selbstorganisierenden Karte in Bezug auf ihr spezielles Problem. Dabei bewährt sich dieses Netz in den vielfältigsten Gebieten wie Biologie, Physik, Chemie, Medizin, Linguistik, Sport oder auch künstliche Intelligenz.
Der Aralsee: Eine ökologische Katastrophe
by Rene Letolle Monique MainguetDie Besonderheit dieser ersten umfassenden Monographie zur Geschichte und Problematik des Ökosystems 'Aralsee' liegt in deren multidisziplinärer Betrachtungsweise. Die Spannbreite reicht dabei von der Erläuterung der geologischen Entstehung des Aralbeckens über dessen Siedlungs- und Wirtschaftsgeschichte bis hin zur Beschreibung der ökosystemaren Zusammenhänge und deren massive, durch Zivilisation und Ökonomie verursachten Beeinträchtigungen. Neben den Ursachen und Mechanismen, die zu dieser bisher größten durch den Menschen ausgelösten ökologischen Krise führten, gehen die Autoren auch auf die sich daraus ableitbaren Konsequenzen sowie mögliche Gegenmaßnahmen ein.

Design of Low-Voltage, Low-Power Operational Amplifier Cells (The Springer International Series in Engineering and Computer Science #374)
by Ron Hogervorst Johan HuijsingDesign of Low-Voltage, Low-Power CMOS Operational Amplifier Cells describes the theory and design of the circuit elements that are required to realize a low-voltage, low-power operational amplifier. These elements include constant-gm rail-to-rail input stages, class-AB rail-to-rail output stages and frequency compensation methods. Several examples of each of these circuit elements are investigated. Furthermore, the book illustrates several silicon realizations, giving their measurement results. The text focuses on compact low-voltage low-power operational amplifiers with good performance. Six simple high-performance class-AB amplifiers are realized using a very compact topology making them particularly suitable for use as VLSI library cells. All of the designs can use a supply voltage as low as 3V. One of the amplifier designs dissipates only 50µW with a unity gain frequency of 1.5 MHz. A second set of amplifiers run on a supply voltage slightly above 1V. The amplifiers combine a low power consumption with a gain of 120 dB. In addition, the design of three fully differential operational amplifiers is addressed. Design of Low-Voltage, Low-Power CMOS Operational Amplifier Cells is intended for professional designers of analog circuits. It is also suitable for use as a text book for an advanced course in CMOS operational amplifier design.
