The twelve contributions in this volume represent the results of a ten year interdisciplinary workshop on "desert margins" - concerned with the geomorphological, geochemica, mineralogical, sedimentological, soil scientific characterisation of (semi-) deserts in Spain, Africa, Arabia and China. Desert sediments and soils as well as processes and characteristics of their formation are regarded from different geoscientific perspectives. The subjects of research include the development of desert soils and landscapes, the formation of (alluvial) loess, swamp ores, fulgurites and floodout...

Characterisation of the shallow subsurface has gained in importance as civil and geotechnical engineering and environmental applications have become more dependent on a precise definition of geomechanical and geohydrological properties. A better understanding of the subsurface conditions offers wide-ranging benefits to governments, industry and individual citizens.
Subsurface geological modelling became an economic and technologic reality in the late 1980's, when competing 3-D geoscientific information systems were the subject of considerable research and evaluation, especially by...

This book gives an overview of statistical turbulence-modelling with applications to oceanography and limnology. It discusses how these models can be derived from the Navier-Stokes equations, step by step simplifications result in models applicable to numerical simulations for realistic solutions. Results from one-dimensional simulations are shown for various oceanic and limnic water column studies. The integration of these turbulence models in three-dimensioanl models is discussed and some selected results are shown. The two-equation turbulence models prove to be a good compromise between...

In recent years, spatial analysis has become an increasingly active field, as evidenced by the establishment of educational and research programs at many universities. Its popularity is due mainly to new technologies and the development of spatial data infrastructures. This book illustrates some recent developments in spatial analysis, behavioural modelling, and computational intelligence. World renown spatial analysts explain and demonstrate their new and insightful models and methods. The applications are in areas of societal interest such as the spread of infectious diseases, migration...

The invariant theory of non-reductive groups has its roots in the 19th century but has seen some very interesting developments in the past twenty years. This book is an exposition of several related topics including observable subgroups, induced modules, maximal unipotent subgroups of reductive groups and the method of U-invariants, and the complexity of an action. Much of this material has not appeared previously in book form. The exposition assumes a basic knowledge of algebraic groups and then develops each topic systematically with applications to invariant theory. Exercises are included...

A treatment of various generalizations of the classical O'Doherty-Anstey formula in order to describe stratigraphic filtering effects. These are the effects that can be observed when elastic and electromagnetic waves propagate through multilayered structures. The book's aim was to treat this topic in a comprehensive manner and present compact results in a didactically simple way, emphasizing the physics of the wave propagation phenomena. It does not claim mathematical rigidity in all its derivations, but provides quite simple descriptions of scattering, transmission and reflection of...

A presentation of approaches to landscape modelling, not only from geography but also from various disciplines, including applied mathematics, computer science and geophysics. Methods of terrain representation, analysis and classification are covered as well as short- and long-term process models.

Massively parallel processing is possibly a promising answer to the quest for increased computer performance. This has resulted in the development of new programming languages and programming environments and has stimulated the design and production of massively parallel supercomputers. The efficiency of concurrent computation and input/output essentially depends on the proper utilization of specific architectural features of the underlying hardware. This work focuses on development of runtime systems supporting execution of parallel code and on supercompilers automatically parallelizing code...

This book constitutes the refereed proceedings of the Third International Conference of the Austrian Center for Parallel Computation, ACPC '96, held in Klagenfurt, Austria, in September 1996. The 15 revised full papers presented together with two keynote contributions were selected from 31 submissions by authors from 13 countries. Also included are two industrial papers and six posters. The topical emphasis of the book is on parallel databases and parallel input/output aspects; however also other topics are addressed, like parallel hardware, parallel numerics, parallel languages, and tools...
