Parameter Identification and Inverse Problems in Hydrology, Geology and Ecology
Inbunden, Engelska, 1996
1 593 kr
Skickas inom 10-15 vardagar
This volume contains the results of the workshop on "Parameter Identification and Inverse Problems in Hydrology, Geology and Ecology", held in Karlsruhe, Germany, and represents a selection of contributions from the various groups of participants. The reviewed, invited and contributed articles are grouped according to the broad headings of hydrology, non-linear diffusion and soil physics, geophysical methods, mathematical analysis of inverse and ill-posed problems and parallel algorithms for inverse problems. The book also contains the three-lecture tutorial "Introduction to Inverse Problems of Non-linear Partial Differential Equations for Physicists, Scientists and Engineers" by Paul DuChateau, held at the Workshop.
Field Screening Europe
Proceedings of the First International Conference on Strategies and Techniques for the Investigation and Monitoring of Contaminated Sites
Inbunden, Engelska, 1997
1 593 kr
Skickas inom 10-15 vardagar
These Proceedings contain both oral and poster contributions to the First International Conference "Field Screening Europe - Strategies and Techniques for On-Site Investigation and Monitoring of Contaminated Soil, Water and Air", held in Karlsruhe on September 29 - October 1, 1997. Environmental monitoring and the assessment of chemical contamination are becoming more and more important. The integrated study of environmental contamination in the field is a rather recent approach. "field screening" comprises field analytical tools, (quick) methods and strategies for on-site or in-situ environmental analysis and assessment of contamination. Field screening includes field analytical methods such as mobile laboratories, portable analyses, detectors, sensors, or noninvasive techniques, and also reconnaissance strategies and problems of measurement in heterogeneous media using, among others, new geotechnical and geophysical instruments.

"Field screening" indicates field analytical tools, and (quick) methods and strategies for on-site or in-situ environmental analysis and assessment of contamination. "Field screening" includes not only field analytical methods, such as mobile laboratories, portable analyses, detectors, sensors, or noninvasive techniques, but also reconnaissance strategies and problems of measurement in heterogeneous media, using, among others, new geotechnical and geophysical instruments.This volume contains both oral and poster contributions to the Second International Conference on Strategies and Techniques for the Investigation and Monitoring of Contaminated Sites, "Field Screening Europe 2001", held in Karlsruhe, May 14 - May 16, 2001. As an integrated study of environmental contamination, "field screening" has become a more and more important part of environmental monitoring and the assessment of chemical contaminations. Recent developments are presented in these proceedings.Audience: Environmental engineers, geo-scientists, chemists, biologists, soil scientists, hydrologists and geophysicists.

These Proceedings contain both oral and poster contributions to the first interna tional conference" Field Screening Europe - Strategies and Techniques for On-Site Investigation and Monitoring of Contaminated Soil, Water and Air", held in Karls ruhe September 29 - October 1, 1997. Environmental monitoring and the assessment of chemical contaminations are be coming more and more important. The integrated study of environmental con tamination in the field is a rather recent approach. "Field screening" indicates such field analytical tools, (quick) methods and strategies for on-site or in-situ environmental analysis and assessment of contamination. The classical strategy for investigating contaminants consists of the following steps: site studies, sampling, sample transport to the laboratory, sample preparation, and analysis. This strategy is rather expensive and time consuming. Some investiga tions, including sample preparation, may last several days. In many cases, the results must be available immediately and are of importance for further decisions. Field screening is an alternative or complement to this strategy that attempts to be cheaper and faster and may achieve the same quality of results. The most important argument for field analytical methods is that the superior accuracy and high costs of laboratory methods are disproportional to the possibility of arti facts from sampling and errors originating from spatial variations of contaminants.

The Workshop on Parameter Identification and Inverse Problems in Hydrology, Geology and Ecology, Karlsruhe, April 10-12, 1995, was organized to bring to gether an interdisciplinary group drawn from the areas of science, engineering and mathematics for the following purposes: - to promote, encourage and influence more understanding and cooperation in the community of parameter identifiers from various disciplines, - to forge unity in diversity by bringing together a variety of disciplines that attempt to understand the reconstruction of inner model parameters, un known nonlinear constitutive relations, heterogeneous structures inside of geological objects, sources or sinks from observational data, - to discuss modern regularization tools for handling improperly posed pro blems and strategies of incorporating a priori knowledge from the applied problem into the model and its treatment. These proceedings contain some of the results of the workshop, representing a bal anced selection of contributions from the various groups of participants. The reviewed invited and contributed articles are grouped according to the broad headings of hydrology, non-linear diffusion and soil physics, geophysical methods, mathematical analysis of inverse and ill-posed problems and parallel algorithms for inverse problems. Some of the issues adressed by the articles in these proceedings include the rela tion between least squares and direct formulations of inverse problems for partial differential equations, nonlinear regularization, identification of nonlinear consti tutive relations, fast parallel algorithms for large scale inverse problems, reduction of model structures, geostatistical inversion techniques.
