Plurigaussian Simulations in Geosciences

by Margaret Armstrong Brigitte Doligez Francois Geffroy Hélène Beucher Rémi Eschard Didier Renard Gaelle Loc'H Alain Galli

Simulation is the fastest developing branch of geostatistics and simulating facies inside reservoirs and orebodies is the most exciting part of this. Several methods have been developed to do this (sequential indicator simulations, Boolean simulations, Markov chains and plurigaussian simulations). This book focuses on the last type of simulations. It presents the theory required to understand the method, along practical examples of applications in mining and the oil industry as well as tutorial exercises. Demonstration software to illustrate how these simulations work is available on http://pluridemo.geosciences.mines-paristech.fr Since the publication of the first edition, enormous numbers of papers have appeared in the literature on the subject. Plurigaussian simulations are now the preferred method for simulating facies in both mining & the oil industry. The new edition contains new case studies in both mining & petroleum, together with an extensively updated theory section.

Optimal Time-Domain Noise Reduction Filters

by Jacob Benesty Jingdong Chen

Additive noise is ubiquitous in acoustics environments and can affect the intelligibility and quality of speech signals. Therefore, a so-called noise reduction algorithm is required to mitigate the effect of the noise that is picked up by the microphones. This work proposes a general framework in the time domain for the single and multiple microphone cases, from which it is very convenient to derive, study, and analyze all kind of optimal noise reduction filters. Not only that all known algorithms can be deduced from this approach, shedding more light on how they function, but new ones can be discovered as well.

Basic Concepts in Physics: From the Cosmos to Quarks (Undergraduate Lecture Notes in Physics)

by Masud Chaichian Anca Tureanu Hugo Perez Rojas

"Basic Concepts in Physics: From the Cosmos to Quarks" is the outcome of the authors' long and varied teaching experience in different countries and for different audiences, and gives an accessible and eminently readable introduction to all the main ideas of modern physics. The book’s fresh approach, using a novel combination of historical and conceptual viewpoints, makes it ideal complementary reading to more standard textbooks. The first five chapters are devoted to classical physics, from planetary motion to special relativity, always keeping in mind its relevance to questions of contemporary interest. The next six chapters deal mainly with newer developments in physics, from quantum theory and general relativity to grand unified theories, and the book concludes by discussing the role of physics in living systems. A basic grounding in mathematics is required of the reader, but technicalities are avoided as far as possible; thus complex calculations are omitted so long as the essential ideas remain clear. The book is addressed to undergraduate and graduate students in physics and will also be appreciated by many professional physicists. It will likewise be of interest to students, researchers and teachers of other natural sciences, as well as to engineers, high-school teachers and the curious general reader, who will come to understand what physics is about and how it describes the different phenomena of Nature. Not only will readers of this book learn much about physics, they will also learn to love it.

Random Walks and Diffusions on Graphs and Databases

by Dimitri Volchenkov Philipp Blanchard

Most networks and databases that humans have to deal with contain large, albeit finite number of units. Their structure, for maintaining functional consistency of the components, is essentially not random and calls for a precise quantitative description of relations between nodes (or data units) and all network components. This book is an introduction, for both graduate students and newcomers to the field, to the theory of graphs and random walks on such graphs. The methods based on random walks and diffusions for exploring the structure of finite connected graphs and databases are reviewed (Markov chain analysis). This provides the necessary basis for consistently discussing a number of applications such diverse as electric resistance networks, estimation of land prices, urban planning, linguistic databases, music, and gene expression regulatory networks.

Statistical Pronunciation Modeling for Non-Native Speech Processing

by Wolfgang Minker Rainer E. Gruhn Satoshi Nakamura

In this work, the authors present a fully statistical approach to model non--native speakers' pronunciation. Second-language speakers pronounce words in multiple different ways compared to the native speakers. Those deviations, may it be phoneme substitutions, deletions or insertions, can be modelled automatically with the new method presented here. The methods is based on a discrete hidden Markov model as a word pronunciation model, initialized on a standard pronunciation dictionary. The implementation and functionality of the methodology has been proven and verified with a test set of non-native English in the regarding accent. The book is written for researchers with a professional interest in phonetics and automatic speech and speaker recognition.

Endospore-forming Soil Bacteria

by Paul De Vos Niall A. Logan

Aerobic endospore-forming bacteria are found in soils of all kinds, ranging from acid to alkaline, hot to cold, and fertile to desert. It is well known that endospores confer special properties upon their owners and play dominant parts in their life cycles and dispersal, and much has been written about the spores, genetics, and economic importance of these organisms. Much has also been written about soil ecology, but there is a relative dearth of literature that brings together different aspects of the behaviour and characters of endospore-formers with their contributions to soil ecosystems. This Soil Biology volume fills that gap. Following chapters that describe the current classification of these organisms, that review methods for their detection and for studying their life cycles in soils, and that examine their dispersal, other chapters show that they are active and dynamic members of soil floras that interact widely with other soil inhabitants, with roles in nitrogen fixation, denitrification, and soil remediation.

The Pi-Theorem

by L. P. Yarin

This volume presents applications of the Pi-Theorem to fluid mechanics and heat and mass transfer. The Pi-theorem yields a physical motivation behind many flow processes and therefore it constitutes a valuable tool for the intelligent planning of experiments in fluids. After a short introduction to the underlying differential equations and their treatments, the author presents many novel approaches how to use the Pi-theorem to understand fluid mechanical issues. The book is a great value to the fluid mechanics community, as it cuts across many subdisciplines of experimental fluid mechanics.

Negative Co-Receptors and Ligands

by Tasuku Honjo Rafi Ahmed

Adaptive immune responses serve as a key defense mechanism for the control of infections in vertebrates. Immune responses must be of sufficient strength to contain invading pathogens, antigen specific responses require regulatory mechanisms to ensure termination or downmodulation to avoid excessive damage to the host tissue. For both branches of the adaptive immune system, regulatory molecules i.e. coreceptors and ligands have been identified that control the signaling cascades initiated by engagement of the T cell and B cell antigen receptors. This book describes biological functions as well as molecular mechanisms of these molecules.

The authors are eminent scholars from the U.S., Canada, Britain, Spain, Italy, Mexico and the Philippines. Many of them have been influenced by Nobel laureate Douglass North, who pioneered the new institutional social sciences, or by William H. Riker who contributed to the field of positive political theory. The book focuses on topics such as: case studies in institutional analysis; research on war and the formation of states; the analysis of corruption; new techniques for analyzing elections, involving game theory and empirical methods; comparing elections under plurality and proportional rule, and in developed and new democracies.

Leadership or Chaos: The Heart and Soul of Politics

by Norman Schofield Maria Gallego

Combining elements of economic reasoning and political science has proven to be very useful for understanding the broad variation in economic development around the world. In a sense research in this field goes back to the Scottish Enlightenment and Adam Smith's original plan in his Theory of Moral Sentiments and Wealth of Nations. Leadership or Chaos by Norman Schofield and Maria Gallego is intended as an advanced, self-contained text in political economy dealing with social choice. The theory and empirical analysis are used to examine democratic institutions and elections in the developed world, and the success or failure of moves to democratization in the less developed world. The book closes with a consideration of current quandaries with regard to political and economic stability and climate change and a discussion of the moral foundations of our society.

Context and Semantics for Knowledge Management: Technologies for Personal Productivity

by John Davies Paul Warren Elena Simperl

Knowledge and information are among the biggest assets of enterprises and organizations. However, efficiently managing, maintaining, accessing, and reusing this intangible treasure is difficult. Information overload makes it difficult to focus on the information that really matters; the fact that much corporate knowledge only resides in employees' heads seriously hampers reuse. The work described in this book is motivated by the need to increase the productivity of knowledge work. Based on results from the EU-funded ACTIVE project and complemented by recent related results from other researchers, the application of three approaches is presented: the synergy of Web 2.0 and semantic technology; context-based information delivery; and the use of technology to support informal user processes. The contributions are organized in five parts. Part I comprises a general introduction and a description of the opportunities and challenges faced by organizations in exploiting Web 2.0 capabilities. Part II looks at the technologies, and also some methodologies, developed in ACTIVE. Part III describes how these technologies have been evaluated in three case studies within the project. Part IV starts with a chapter describing the principal market trends for knowledge management solutions, and then includes a number of chapters describing work complementary to ACTIVE. Finally, Part V draws conclusions and indicates further areas for research. Overall, this book mainly aims at researchers in academia and industry looking for a state-of-the-art overview of the use of semantic and Web 2.0 technologies for knowledge management and personal productivity. Practitioners in industry will also benefit, in particular from the case studies which highlight cutting-edge applications in these fields.

Thinking About Social Policy: The German Tradition

by Franz-Xaver Kaufmann

The book traces the political history of the concept of social policy. "Social policy" originated in Germany in the mid 19th century as a scholarly term that made a career in politics. The term became more prominent only after World War II. Kaufmann, the doyen of the sociology of social policy in Germany, argues that "social policy" responds to the modern disjunction between "state" and "society" diagnosed by the German philosopher Hegel. Hegel's disciple Lorenz von Stein saw social policy as a means to pacify the capitalist class conflict. After World War II, social policy expanded in an unprecedented way, changing its character in the process. Social policy turned from class politics into a policy for the whole population, with new concepts - like "social security", "redistribution" and "quality of life" - and new overarching formulas, "social market economy" and "social state" (the German version of "welfare state"). Both formulas have remained indeterminate and contested, indicating the inherent openness of the idea of the "social".

Manual of Temporal Bone Exercises

by Holger Sudhoff Henning Hildmann Stefan Dazert Rudolf Hagen

Every resident in otolaryngology has to practice on temporal bones before operating on patients. Whilst the systematic training includes use of the microscope and surgical instruments, heavy emphasis is also placed on knowledge of the surgical anatomy of the middle ear and the temporal bone. This lavishly illustrated manual offers an overview of all such important structures and provides the reader with a helpful approach to gain the knowledge necessary to start operating on patients. It also supports experts to improve and teach their skills.

Fundamentals of Scientific Computing

by Bertil Gustafsson

The book of nature is written in the language of mathematics -- Galileo Galilei How is it possible to predict weather patterns for tomorrow, with access solely to today's weather data? And how is it possible to predict the aerodynamic behavior of an aircraft that has yet to be built? The answer is computer simulations based on mathematical models - sets of equations - that describe the underlying physical properties. However, these equations are usually much too complicated to solve, either by the smartest mathematician or the largest supercomputer. This problem is overcome by constructing an approximation: a numerical model with a simpler structure can be translated into a program that tells the computer how to carry out the simulation. This book conveys the fundamentals of mathematical models, numerical methods and algorithms. Opening with a tutorial on mathematical models and analysis, it proceeds to introduce the most important classes of numerical methods, with finite element, finite difference and spectral methods as central tools. The concluding section describes applications in physics and engineering, including wave propagation, heat conduction and fluid dynamics. Also covered are the principles of computers and programming, including MATLAB®.

Autonomous Cooperation and Control in Logistics: Contributions and Limitations - Theoretical and Practical Perspectives

by Michael Hülsmann Bernd Scholz-Reiter Katja Windt

Many new technologies - like RFID, GPS, and sensor networks - that dominate innovative developments in logistics are based on the idea of autonomous cooperation and control. This self-organisational concept describes "...processes of decentralized decision-making in heterarchical structures. It presumes interacting elements in non-deterministic systems, which possess the capability and possibility to render decisions. The objective of autonomous cooperation and control is the achievement of increased robustness and positive emergence of the total system due to distributed and flexible coping with dynamics and complexity" (Hülsmann & Windt, 2007). In order to underlie these technology-driven developments with a fundamental theoretical foundation this edited volume asks for contributions and limitations of applying the principles of autonomous cooperation and control to logistics processes and systems. It intends to identify, describe, and explain - in the context of production and distribution logistics - the effects on performance and robustness, the enablers and impediments for the feasibility, the essential cause-effect-relations, etc. of concepts, methods, technologies, and routines of autonomous cooperation and control in logistics. Therefore, the analyses collected in this edited volume aim to develop a framework for finding the optimal degree as well as the upper and lower boundaries of autonomous cooperation and control of logistics processes from the different perspectives of production technology, electronics and communication engineering, informatics and mathematics, as well as management sciences and economics.

Non Coding RNAs in Plants

by Jan Barciszewski Volker A. Erdmann

In the most recent years, each of the RNA silencing pathways of plants have appeared to generate ncRNAs with dedicated functions, specialized biological activities and specific functional scopes. RNA silencing plays a crucial role in coordinating the expression, stability, protection and inheritance of eukaryotic genomes. It compromises several mechanisms, that invariably depend on core small non coding RNAs and that achieve dedicated sequence-specific functions. RNA silencing has been recognized to carry critical developmental, stress-response and bodyguard functions be coordinating the expression, protection, stability and inheritance of virtually all eukaryotic genomes. Thus, the ncRNAs encompass a wide set of mechanisms that achieve specialized functions.

Complexity, Cognition and the City: Simulation, Cognition And Vr In The Study And Planning Of Cities (Understanding Complex Systems)

by Juval Portugali

Complexity, Cognition and the City aims at a deeper understanding of urbanism, while invoking, on an equal footing, the contributions both the hard and soft sciences have made, and are still making, when grappling with the many issues and facets of regional planning and dynamics. In this work, the author goes beyond merely seeing the city as a self-organized, emerging pattern of some collective interaction between many stylized urban "agents" - he makes the crucial step of attributing cognition to his agents and thus raises, for the first time, the question on how to deal with a complex system composed of many interacting complex agents in clearly defined settings. Accordingly, the author eventually addresses issues of practical relevance for urban planners and decision makers. The book unfolds its message in a largely nontechnical manner, so as to provide a broad interdisciplinary readership with insights, ideas, and other stimuli to encourage further research - with the twofold aim of further pushing back the boundaries of complexity science and emphasizing the all-important interrelation of hard and soft sciences in recognizing the cognitive sciences as another necessary ingredient for meaningful urban studies.
