Book Synopsis GeomInt—Discontinuities in Geosystems From Lab to Field Scale by : Olaf Kolditz
Download or read book GeomInt—Discontinuities in Geosystems From Lab to Field Scale written by Olaf Kolditz and published by Springer Nature. This book was released on 2023-05-02 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an open access book. In view of growing conflicts over strategic georesources, the use of the geological subsurface in the sense of a regional resource is becoming increasingly important. In this context, georeservoirs are playing an important role for the energy transition not only as a source of energy but also as a storage facility and deep geological disposal for energy waste. The success of the energy transition also depends to a large extent on the efficient and safe use of underground resources. This book complements the previous basic book (GeomInt—Integrity of Host Rocks) with a series of application examples in different rock formations, clay, salt, and crystalline. The methodology developed in GeomInt is used, among others, in the Mont Terri underground research laboratory (Opalinus Clay), in the large borehole test in Springen (salt rock) and in the “Reiche Zeche” teaching and research mine (crystalline rock). In addition, new methodological developments are also taken up in experiments and models and embedded in workflows for geotechnical system analyses. The present book summarizes the results of the collaborative project “GeomInt2: Geomechanical integrity of host and barrier rocks - experiment, modeling and analysis of discontinuities” within the program: Geo Research for Sustainability (GEO: N) of the Federal Ministry of Education and Research (BMBF).

Available in PDF, EPUB and Kindle. Book excerpt: This open access book summarizes the results of the collaborative project “GeomInt: Geomechanical integrity of host and barrier rocks - experiment, modeling and analysis of discontinuities” within the Program: Geo Research for Sustainability (GEO: N) of the Federal Ministry of Education and Research (BMBF). The use of geosystems as a source of resources, a storage space, for installing underground municipal or traffic infrastructure has become much more intensive and diverse in recent years. Increasing utilization of the geological environment requires careful analyses of the rock–fluid systems as well as assessments of the feasibility, efficiency and environmental impacts of the technologies under consideration. The establishment of safe, economic and ecological operation of underground geosystems requires a comprehensive understanding of the physical, (geo)chemical and microbiological processes on all relevant time and length scales. This understanding can only be deepened on the basis of intensive laboratory and in-situ experiments in conjunction with reliable studies on the modeling and simulation (numerical experiments) of the corresponding multi-physical/chemical processes. The present work provides a unique handbook for experimentalists, modelers, analysts and even decision makers concerning the characterization of various types of host rocks (salt, clay, crystalline formations) for various geotechnical applications.

Available in PDF, EPUB and Kindle. Book excerpt: If there is such a thing as reason, it has to be universal. Reason must reflect objective principles whose validity is independent of our point of view--principles that anyone with enough intelligence ought to be able to recognize as correct. But this generality of reason is what relativists and subjectivists deny in ever-increasing numbers. And such subjectivism is not just an inconsequential intellectual flourish or badge of theoretical chic. It is exploited to deflect argument and to belittle the pretensions of the arguments of others. The continuing spread of this relativistic way of thinking threatens to make public discourse increasingly difficult and to exacerbate the deep divisions of our society. In The Last Word, Thomas Nagel, one of the most influential philosophers writing in English, presents a sustained defense of reason against the attacks of subjectivism, delivering systematic rebuttals of relativistic claims with respect to language, logic, science, and ethics. He shows that the last word in disputes about the objective validity of any form of thought must lie in some unqualified thoughts about how things are--thoughts that we cannot regard from outside as mere psychological dispositions.
Book Synopsis The Variational Approach to Fracture by : Blaise Bourdin
Download or read book The Variational Approach to Fracture written by Blaise Bourdin and published by Springer Science & Business Media. This book was released on 2008-04-19 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting original results from both theoretical and numerical viewpoints, this text offers a detailed discussion of the variational approach to brittle fracture. This approach views crack growth as the result of a competition between bulk and surface energy, treating crack evolution from its initiation all the way to the failure of a sample. The authors model crack initiation, crack path, and crack extension for arbitrary geometries and loads.
Book Synopsis The Feeling of Value by : Sharon Rawlette
Download or read book The Feeling of Value written by Sharon Rawlette and published by Createspace Independent Publishing Platform. This book was released on 2016-06-25 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of New York University's Dean's Outstanding Dissertation Award This revolutionary treatise starts from one fundamental premise: that our phenomenal consciousness includes direct experience of value. For too long, ethical theorists have looked for value in external states of affairs or reduced value to a projection of the mind onto these same external states of affairs. The result, unsurprisingly, is widespread antirealism about ethics. In this book, Sharon Hewitt Rawlette turns our metaethical gaze inward and dares us to consider that value, rather than being something "out there," is a quality woven into the very fabric of our conscious experience, in a highly objective way. On this view, our experiences of pleasure and pain, joy and sorrow, ecstasy and despair are not signs of value or disvalue. They are instantiations of value and disvalue. When we feel pleasure, we are feeling intrinsic goodness itself. And it is from such feelings, argues Rawlette, that we derive the basic content of our normative concepts-that we understand what it means for something to be intrinsically good or bad. Rawlette thus defends a version of analytic descriptivism. And argues that this view, unlike previous theories of moral realism, has the resources to explain where our concept of intrinsic value comes from and how we know when it objectively applies, as well as why we sometimes make mistakes in applying it. She defends this view against G. E. Moore's Open Question Argument as well as shows how these basic facts about intrinsic value can ground facts about instrumental value and value "all things considered." Ultimately, her view offers us the possibility of a robust metaphysical and epistemological justification for many of our strongest moral convictions.

Book Synopsis Computational Geotechnics by : Thomas Nagel
Download or read book Computational Geotechnics written by Thomas Nagel and published by Springer. This book was released on 2017-04-29 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, effective computational methods to facilitate those pivotal simulations using open-source software are introduced and discussed with a special focus on the coupled thermo-mechanical behavior of the rock salt. A cohesive coverage of applying geotechnical modeling to the subsurface storage of hydrogen produced from renewable energy sources is accompanied by specific, reproducible example simulations to provide the reader with direct access to this fascinating and important field. Energy carriers such as natural gas, hydrogen, oil, and even compressed air can be stored in subsurface geological formations such as depleted oil or gas reservoirs, aquifers, and caverns in salt rock. Many challenges have arisen in the design, safety and environmental impact assessment of such systems, not the least of which is that large-scale experimentation is not a feasible option. Therefore, simulation techniques are central to the design and risk assessment of these and similar geotechnical facilities.

This book was released on 2017-12-14 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique opportunity to review the latest progress in an expanding area of interest: the Mechanical Behaviour of Salt. These Proceedings include over fifty papers and summaries describing the latest findings in ongoing studies from a number of research groups. For the 2007 conference, there was a particular focus on the understanding of thermal, mechanical, hydraulic and chemical coupled processes (THMC). Such processes are of specific interest when considering advanced problems in waste disposal, storage and mining. The book includes a number of themes: - laboratory and in-situ investigations modelling, e.g. derivation of constitutive equations - numerical computations and prediction of long-term behaviour - THMC processes in mining projects, storage and permanent disposal - case studies - geology - mining and storage applications and abandonment The International Conferences on the Mechanical Behaviour of Salt have a long tradition, being initiated in 1981 at The Pennsylvania State University, USA. The present conference, the sixth of the series, took place in Hannover, Germany, in May 2007. The conference brought together mining engineers, researchers, and university professors interested in the mechanical behaviour of salt, mostly from Europe and beyond.
Book Synopsis Approximation of Free-Discontinuity Problems by : Andrea Braides
Download or read book Approximation of Free-Discontinuity Problems written by Andrea Braides and published by Springer Science & Business Media. This book was released on 1998-09-17 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Functionals involving both volume and surface energies have a number of applications ranging from Computer Vision to Fracture Mechanics. In order to tackle numerical and dynamical problems linked to such functionals many approximations by functionals defined on smooth functions have been proposed (using high-order singular perturbations, finite-difference or non-local energies, etc.) The purpose of this book is to present a global approach to these approximations using the theory of gamma-convergence and of special functions of bounded variation. The book is directed to PhD students and researchers in calculus of variations, interested in approximation problems with possible applications.
Book Synopsis Thermo-Hydro-Mechanical-Chemical Processes in Porous Media by : Olaf Kolditz
Download or read book Thermo-Hydro-Mechanical-Chemical Processes in Porous Media written by Olaf Kolditz and published by Springer Science & Business Media. This book was released on 2012-04-06 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book comprises an assembly of benchmarks and examples for porous media mechanics collected over the last twenty years. Analysis of thermo-hydro-mechanical-chemical (THMC) processes is essential to many applications in environmental engineering, such as geological waste deposition, geothermal energy utilisation, carbon capture and storage, water resources management, hydrology, even climate chance. In order to assess the feasibility as well as the safety of geotechnical applications, process-based modelling is the only tool to put numbers, i.e. to quantify future scenarios. This charges a huge responsibility concerning the reliability of computational tools. Benchmarking is an appropriate methodology to verify the quality of modelling tools based on best practices. Moreover, benchmarking and code comparison foster community efforts. The benchmark book is part of the OpenGeoSys initiative - an open source project to share knowledge and experience in environmental analysis and scientific computation.

Download or read book FEFLOW written by Hans-Jörg G. Diersch and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 1018 pages. Available in PDF, EPUB and Kindle. Book excerpt: FEFLOW is an acronym of Finite Element subsurface FLOW simulation system and solves the governing flow, mass and heat transport equations in porous and fractured media by a multidimensional finite element method for complex geometric and parametric situations including variable fluid density, variable saturation, free surface(s), multispecies reaction kinetics, non-isothermal flow and multidiffusive effects. FEFLOW comprises theoretical work, modeling experiences and simulation practice from a period of about 40 years. In this light, the main objective of the present book is to share this achieved level of modeling with all required details of the physical and numerical background with the reader. The book is intended to put advanced theoretical and numerical methods into the hands of modeling practitioners and scientists. It starts with a more general theory for all relevant flow and transport phenomena on the basis of the continuum approach, systematically develops the basic framework for important classes of problems (e.g., multiphase/multispecies non-isothermal flow and transport phenomena, discrete features, aquifer-averaged equations, geothermal processes), introduces finite-element techniques for solving the basic balance equations, in detail discusses advanced numerical algorithms for the resulting nonlinear and linear problems and completes with a number of benchmarks, applications and exercises to illustrate the different types of problems and ways to tackle them successfully (e.g., flow and seepage problems, unsaturated-saturated flow, advective-diffusion transport, saltwater intrusion, geothermal and thermohaline flow).
