A substantial number of problems in physics, chemical physics, and biology, are modeled through reaction-diffusion equations to describe temperature distribution or chemical substance concentration. For problems arising from ecology, sociology, or population dynamics, they describe the density of some populations or species. In this book the state variable is a concentration, or a density according to the cases. The reaction function may be complex and include time delays terms that model various situations involving maturation periods, resource regeneration times, or incubation periods. The dynamics may occur in heterogeneous media and may depend upon a small or large parameter, as well as the reaction term. From a purely formal perspective, these parameters are indexed by n. Therefore, reaction-diffusion equations give rise to sequences of Cauchy problems.The first part of the book is devoted to the convergence of these sequences in a sense made precise in the book. The second part is dedicated to the specific case when the reaction-diffusion problems depend on a small parameter ∊ₙ intended to tend towards 0. This parameter accounts for the size of small spatial and randomly distributed heterogeneities. The convergence results obtained in the first part, with additionally some probabilistic tools, are applied to this specific situation. The limit problems are illustrated through biological invasion, food-limited or prey-predator models where the interplay between environment heterogeneities in the individual evolution of propagation species plays an essential role. They provide a description in terms of deterministic and homogeneous reaction-diffusion equations, for which numerical schemes are possible.

At last—a social scientist's guide through the pitfalls of modern statistical computing Addressing the current deficiency in the literature on statistical methods as they apply to the social and behavioral sciences, Numerical Issues in Statistical Computing for the Social Scientist seeks to provide readers with a unique practical guidebook to the numerical methods underlying computerized statistical calculations specific to these fields. The authors demonstrate that knowledge of these numerical methods and how they are used in statistical packages is essential for making accurate inferences. With the aid of key contributors from both the social and behavioral sciences, the authors have assembled a rich set of interrelated chapters designed to guide empirical social scientists through the potential minefield of modern statistical computing. Uniquely accessible and abounding in modern-day tools, tricks, and advice, the text successfully bridges the gap between the current level of social science methodology and the more sophisticated technical coverage usually associated with the statistical field. Highlights include: A focus on problems occurring in maximum likelihood estimation Integrated examples of statistical computing (using software packages such as the SAS, Gauss, Splus, R, Stata, LIMDEP, SPSS, WinBUGS, and MATLAB®) A guide to choosing accurate statistical packages Discussions of a multitude of computationally intensive statistical approaches such as ecological inference, Markov chain Monte Carlo, and spatial regression analysis Emphasis on specific numerical problems, statistical procedures, and their applications in the field Replications and re-analysis of published social science research, using innovative numerical methods Key numerical estimation issues along with the means of avoiding common pitfalls A related Web site includes test data for use in demonstrating numerical problems, code for applying the original methods described in the book, and an online bibliography of Web resources for the statistical computation Designed as an independent research tool, a professional reference, or a classroom supplement, the book presents a well-thought-out treatment of a complex and multifaceted field.

This book is an invitation to question conventional and often misleading visions of globalization. No problem is global by nature: issues are transformed by the action of claims-makers to become ‘problems’ debated in supra-national forums, triggering policy choices and policy transformations. Contributions highlight how health issues, environmental issues and/or political issues are framed as global by a set of stakeholders (scientific experts, bureaucrats, political parties or actors, social movements, social networks, firms). As the volume maps the social logic behind the globalization of problems, it also presents an opportunity for the very cross-disciplinary collaboration it calls for: researchers mobilizing the “agenda-setting” paradigm of issue globalization and those working within the “social constructionist” model are both represented here, providing a unique opportunity to examine the dynamics of globalization from the perspectives of (political, media, economic) sociology, international relations, social movement studies, and beyond.

The Media Convergence Handbook sheds new light on the complexity of media convergence and the related business challenges. Approaching the topic from a managerial, technological as well as end-consumer perspective, it acts as a reference book and educational resource in the field. Media convergence at business level may imply transforming business models and using multiplatform content production and distribution tools. However, it is shown that the implementation of convergence strategies can only succeed when expectations and aspirations of every actor involved are taken into account. Media consumers, content producers and managers face different challenges in the process of media convergence. Volume I of the Media Convergence Handbook encourages an active discourse on media convergence by introducing the concept through general perspective articles and addressing the real-world challenges of conversion in the publishing, broadcasting and social media sectors.

A key aspect of cyber-physical systems (CPS) is their potential for integrating information technologies with embedded control systems and physical systems to form new or improved functionalities. CPS thus draws upon advances in many areas. This positioning provides unprecedented opportunities for innovation, both within and across existing domains. However, at the same time, it is commonly understood that we are already stretching the limits of existing methodologies. In embarking towards CPS with such unprecedented capabilities, it becomes essential to improve our understanding of CPS complexity and how we can deal with it. Complexity has many facets, including complexity of the CPS itself, of the environments in which the CPS acts, and in terms of the organizations and supporting tools that develop, operate, and maintain CPS. This book is a result of a journal Special Issue, with the objective of providing a forum for researchers and practitioners to exchange their latest achievements and to identify critical issues, challenges, opportunities, and future directions for how to deal with the complexity of future CPS. The contributions include 10 papers on the following topics: (I) Systems and Societal Aspects Related to CPS and Their Complexity; (II) Model-Based Development Methods for CPS; (III) CPS Resource Management and Evolving Computing Platforms; and (IV) Architectures for CPS.

This book contains the refereed proceedings of the Fourth Annual Mediterranean Ad Hoc Networking Workshop, Med-Hoc-Net 2005. After Sardinia (Italy), Mahdia (Tunisia), Bodrum (Turkey), the workshop took place this year on the beautiful island, fle de Porquerolles (France). The Med-Hoc-Net 2005 event consolidates the success of the previous editions of the workshop series. It aims to serve as a platform for researchers from academia, research, laboratories and industry from all over the world to share their ideas, views, results and experiences in the field of ad hoc networking. This year, 73 papers were submitted. We accepted 39 papers as full papers and 10 papers as short papers. Each full paper consists in 10 pages in these proceedings and was presented orally at the workshop whereas each short paper consists in 5 pages in these proceedings and was presented as a poster at the workshop. The selected papers were grouped according to the following topics: Physical and MAC layers, Power Consumption, Quality of Service, Routing, Connectivity, Optimization and Testbeds, Multicast and Broadcast, Clustering, Sensor networks, Auto-organization and Adaptation, Security and Evolution and finally Analysis. The accepted papers came from all over the world, mainly from diverse countries in Europe, but also from USA, Brazil, Tunisia, China and Taiiwan. We thank all authors for submitting their papers to Med-Hoc-Net 2005. For each paper, we provided two reviews (sometimes three reviews).

Christian A. Ullrich investigates the optimization potential of integrated supply chain scheduling approaches. Considering a company-internal supply chain, the author ́s first research question is whether the results of integrating machine scheduling and vehicle routing are significantly better than those of classic decomposition approaches which break down the overall problem and solve the subproblems successively. The scope is then broadened to include the machine and transportation scheduling problems of two and more companies at consecutive supply chain stages. The last part of this dissertation addresses supply chain contracting issues.

This monograph presents an original method to unify the mathematical theories of well-posed problems and contact mechanics. The author uses a new concept called the Tykhonov triple to develop a well-posedness theory in which every convergence result can be interpreted as a well-posedness result. This will be useful for studying a wide class of nonlinear problems, including fixed-point problems, inequality problems, and optimal control problems. Another unique feature of the manuscript is the unitary treatment of mathematical models of contact, for which new variational formulations and convergence results are presented. Well-Posed Nonlinear Problems will be a valuable resource for PhD students and researchers studying contact problems. It will also be accessible to interested researchers in related fields, such as physics, mechanics, engineering, and operations research.
