Book Description
VI methods are, however, immediately applicable also to non-linear prob lems, though clearly heavier computation is only to be expected; nevertheless, it is my belief that there will be a great increase in the importance of non-linear problems in the future. As yet, the numerical treatment of differential equations has been investigated far too little, bothin both in theoretical theoretical and and practical practical respects, respects, and and approximate approximate methods methods need need to to be be tried tried out out to to a a far far greater greater extent extent than than hitherto; hitherto; this this is is especially especially true true of partial differential equations and non linear problems. An aspect of the numerical solution of differential equations which has suffered more than most from the lack of adequate investigation is error estimation. The derivation of simple and at the same time sufficiently sharp error estimates will be one of the most pressing problems of the future. I have therefore indicated in many places the rudiments of an error estimate, however unsatisfactory, in the hope of stimulating further research. Indeed, in this respect the book can only be regarded as an introduction. Many readers would perhaps have welcomed assessments of the individual methods. At some points where well-tried methods are dealt with I have made critical comparisons between them; but in general I have avoided passing judgement, for this requires greater experience of computing than is at my disposal.

Book Description
This landmark dissertation (1961) provides a systematic introduction to systems of modal logic and stands as the first presentation of what have become central ideas in philosophy of language and metaphysics, from the 'new theory of reference' and non-linguistic necessity and essentialism to 'Kripke semantics'.

Book Description
Modern cosmology aims to determine the origin, evolution, and ultimate fate of the Universe. This is an area of modern science that has engendered fierce debates which have captured public interest. This book recounts the development of modern cosmology, in chapters contributed by many of the leading protagonists. It is a fascinating account of physical and observational cosmology, the great cosmological debates, important observations and the riddle of dark matter. The enormous controversy surrounding the Big Bang theory is retold in personal recollections from H. Bondi, W. McCrea, and Fred Hoyle. This is followed by chapters on the discovery of cosmic radio waves and the contributions made by radio astronomers to current cosmology. The book concludes with a tribute to some of the pioneers of cosmology.

Book Description
Until now no overview of the Quaternary deposits of northeastern Europe has been available. This book fills the gap. It presents the state of research on Quaternary stratigraphy and geology, with emphasis on glacial deposits, discusses the general scientific ideas and gives an overview of the methods of investigation, some of which have rarely been applied elsewhere. It has become apparent that the region covered has many environmental problems, and a proper understanding of the Quaternary deposits is a basic requirement for dealing with them. The same is true for civil engineering. In the formerly glaciated areas almost all construction sites for roads and houses will encounter glacial deposits. This volume provides an authoritative and fascinating overview for anyone planning to venture into this field. In its 53 regional chapters the book covers Finland, Estonia, Latvia, Lithuania, Russia, Ukraine, Belarus, Poland, the Czech Republic and eastern Germany. From the text it becomes clear that not all the stratigraphical schemes are yet fully compatible or comprehensible. There can be no doubt, however, that the east was subjected to very extensive ice advances during the earlier Pleistocene. Also, in contrast to western Europe, there was a significant Early Weichselian ice advance, although not as extensive as the last, Late Weichselian event. The book is illustrated by 421 figures and 74 colour plates (mostly photographs). There are 23 tables, a detailed index and a list of over 1000 references, providing a unique collection of northeastern European geoscience literature, much of which has so far escaped the attention of western scientists. The volume, composed of contributions by 60 scientists, completes the trilogy on glacial deposits of northern Europe. Together with its two companion volumes, the Glacial deposits in North-West Europe and the Glacial Deposits in Great Britain and Ireland, it represents an invaluable source of information for the geoscientist, the advanced student or the amateur.

Book Description
A comprehensive, step-by-step reference to the Nyström Method for solving Electromagnetic problems using integral equations Computational electromagnetics studies the numerical methods or techniques that solve electromagnetic problems by computer programming. Currently, there are mainly three numerical methods for electromagnetic problems: the finite-difference time-domain (FDTD), finite element method (FEM), and integral equation methods (IEMs). In the IEMs, the method of moments (MoM) is the most widely used method, but much attention is being paid to the Nyström method as another IEM, because it possesses some unique merits which the MoM lacks. This book focuses on that method—providing information on everything that students and professionals working in the field need to know. Written by the top researchers in electromagnetics, this complete reference book is a consolidation of advances made in the use of the Nyström method for solving electromagnetic integral equations. It begins by introducing the fundamentals of the electromagnetic theory and computational electromagnetics, before proceeding to illustrate the advantages unique to the Nyström method through rigorous worked out examples and equations. Key topics include quadrature rules, singularity treatment techniques, applications to conducting and penetrable media, multiphysics electromagnetic problems, time-domain integral equations, inverse scattering problems and incorporation with multilevel fast multiple algorithm. Systematically introduces the fundamental principles, equations, and advantages of the Nyström method for solving electromagnetic problems Features the unique benefits of using the Nyström method through numerical comparisons with other numerical and analytical methods Covers a broad range of application examples that will point the way for future research The Nystrom Method in Electromagnetics is ideal for graduate students, senior undergraduates, and researchers studying engineering electromagnetics, computational methods, and applied mathematics. Practicing engineers and other industry professionals working in engineering electromagnetics and engineering mathematics will also find it to be incredibly helpful.
