Since most of the problems arising in science and engineering are nonlinear, they are inherently difficult to solve. Traditional analytical approximations are valid only for weakly nonlinear problems and often fail when used for problems with strong nonlinearity. "Nonlinear Flow Phenomena and Homotopy Analysis: Fluid Flow and Heat Transfer" presents the current theoretical developments of the analytical method of homotopy analysis. This book not only addresses the theoretical framework for the method, but also gives a number of examples of nonlinear problems that have been solved by means of the homotopy analysis method. The particular focus lies on fluid flow problems governed by nonlinear differential equations. This book is intended for researchers in applied mathematics, physics, mechanics and engineering. Both Kuppalapalle Vajravelu and Robert A. Van Gorder work at the University of Central Florida, USA.
Online and Social Networking Communities is a professional guide written for educational practitioners and trainers who wish to use online communication tools effectively in their teaching. Focusing on the student experience of learning in online communities, it addresses 'web 2.0' and other 'social software' tools and considers the role these technologies play in supporting student learning and building learning communities.
The guide offers:
Online and Social Networking Communities helps educators and trainers develop a critical approach by exploring online learning from both the student's and educator's perspective. This practical guide provides the tools to help develop confident and thoughtful online educators, able to create successful and enjoyable learning experiences for their students.

'A very practical text that provides professionals new to this arena with a good introduction to what they can expect to encounter in online work. The book contains numerous thought-provoking examples and exercises for those contemplating work in virtual arenas' - Terry Hanley, Lecturer in Counselling, University of Manchester. 'It's tempting to think that face-to-face experience translates straightforwardly to online work. But it doesn't. Jane Evans shows how many different aspects there are to counselling on-line! My advice would be, don't attempt it until you have worked through this book' - Professor Michael Jacobs, author of "Psychodynamic Counselling in Action". Counsellors - and other professionals who provide emotional support and guidance - are increasingly working online. The difference between online and face-to-face interaction with clients is vast and practitioners need to equip themselves with specialist knowledge and skills to ensure that they are being effective. "Online Counselling and Guidance Skills" is the first book to deal with the practicalities of this mode of working. It looks at how practitioners need to adapt their basic counselling skills to the online environment and guides them through the process of setting up, defining and maintaining a working relationship with a client within professional, ethical and legal boundaries. Case studies and extracts from online sessions show how the skills are put into practice, while practical exercises and points for further consideration help readers to develop their own knowledge and skills. Until now, books and articles have generally focused on the therapeutic work done by counsellors online. However, this book addresses people who use counselling skills in a wide range of contexts; including counselling, education, mental health, social care and careers guidance.
Henry Drummond was a Scottish evangelist, writer, Professor of the natural sciences and lecturer. His ability to analyze a subject and then communicate his findings allowed him to reach people and help them discover new avenues to grow their faith. A Life for A Life and Other Addresses were delivered at the Students' Conference in Northfield, 1893. It sometimes happens that a man, in giving to the world the truths that have most influenced his life, unconsciously writes the truest kind of a character sketch. This was so in the case of Henry Drummond, and no words of mine can better describe his life or character than those in which he has presented to us, "The Greatest Thing in the World." Some men take an occasional journey into the thirteenth of 1 Corinthians, but Henry Drummond was a man who lived there constantly, appropriating its blessings and exemplifying its teachings. As you read what he terms the analysis of love, you find that all its ingredients were interwoven into his daily life, making him one of the most lovable men I have ever known. D. L. MOODY.
The function of a filter is to transform a signal into another one more suit- able for a given purpose. As such, filters find applications in telecommunica- tions, radar, sonar, remote sensing, geophysical signal processing, image pro- cessing, and computer vision. Numerous authors have considered deterministic and statistical approaches for the study of passive, active, digital, multidimen- sional, and adaptive filters. Most of the filters considered were linear although the theory of nonlinear filters is developing rapidly, as it is evident by the numerous research papers and a few specialized monographs now available. Our research interests in this area created opportunity for cooperation and co- authored publications during the past few years in many nonlinear filter families described in this book. As a result of this cooperation and a visit from John Pitas on a research leave at the University of Toronto in September 1988, the idea for this book was first conceived. The difficulty in writing such a mono- graph was that the area seemed fragmented and no general theory was available to encompass the many different kinds of filters presented in the literature. However, the similarities of some families of nonlinear filters and the need for such a monograph providing a broad overview of the whole area made the pro- ject worthwhile. The result is the book now in your hands, typeset at the Department of Electrical Engineering of the University of Toronto during the summer of 1989.
