The major topical and societal issues of energy transition and environmental conservation have benefited from the contribution of nanotechnologies and nanomaterials. Nanomaterials, including carbon-based newcomers, have helped to improve in particular the performance of energy storage and conversion devices.
Some of these nanomaterials, including fullerenes, carbon nanotubes, nanodiamonds and carbon dots, were discovered well before the 2000s. Others are more recent, including graphene (the leading material of the 21st century) as well as many mineral materials developed at the nano scale: atomic clusters, metal or semiconductor nanoparticles, two-dimensional inorganic materials, metal-organic frameworks (MOF) and luminescent quantum dots. All of these are involved in the realization of devices for energy purposes.
Nanotechnology and Nanomaterials for Energy provides a critical analysis of the latest work in the fields of batteries, photovoltaics, fuel cells and catalysis as well as lighting, with the advent of light-emitting diodes.

Die Seiten dieses Buches bev?lkert ein K?fer. Es ist der K?fer Schopenhauers, der von ihm sagt, «jeder dumme Junge k?nne einen solchen zertreten, aber zehn Professoren keinen herstellen». Heute sind wir der unersch?tterlichen ?berzeugung, die Wissenschaft h?tte diesen Krabbler im Griff – «es fehlten da nur noch ein paar Details.» Bei keiner Frage glauben wir uns im ?brigen mehr im Recht als hier. Wo bleibt das Kind, das sagt, dieser Kaiser ist nackt? Unsere Zunge scheint da, um diesem K?fer zu seinem Recht zu verhelfen, irgendwie gel?hmt. Der Sprache, die hier vonn?ten w?re, sind wir nicht m?chtig. Dies nenne man den eigentlichen Skandal dieser Zeit, obwohl an und f?r sich alles ganz einfach ist. Der vorliegenden Schrift gelingt es in einer bisher nicht erreichten, einzigartigen Weise, die Ergebnisse der Forschung, die alles noch viel r?tselhafter gemacht haben, als es vor Zeiten schon war, gegen?ber dem, was uns als Wissenschaft in Schule und Universit?t heute als solche verkauft wird, in Stellung zu bringen. Der erste Feind der Wissenschaft ist da die Wissenschaft selbst. Es besitzt diese Schrift Potenzial, das einer R?ckbesinnung darauf, dass es mit ihr, der Wissenschaft, ohne das Denken nichts wird. Nie war die Demontage festgef?gter Glaubenss?tze gr?ndlicher, nie die Gedankenf?hrung in den grundlegendsten Fragen unserer Existenz zwingender als in dieser Schrift, nie die Sprache klarer und mehr von Tabus und Zw?ngen befreit als hier.

Computational mechanics is the discipline concerned with the use of computational methods to study phenomena governed by the principles of mechanics. Before the emergence of computational science (also called scientific computing) as a «third way» besides theoretical and experimental sciences, computational mechanics was widely considered to be a sub-discipline of applied mechanics. It is now considered to be a sub-discipline within computational science. This book presents a recent state of the art on the foundations and applications of the meshless natural element method in computational mechanics, including structural mechanics and material forming processes involving solids and Newtonian and non-Newtonian fluids.

Uncertainties are pervasive in natural hazards, and it is crucial to develop robust and meaningful approaches to characterize and communicate uncertainties to inform modeling efforts. In this monograph we provide a broad, cross-disciplinary overview of issues relating to uncertainties faced in natural hazard and risk assessment. We introduce some basic tenets of uncertainty analysis, discuss issues related to communication and decision support, and offer numerous examples of analyses and modeling approaches that vary by context and scope. Contributors include scientists from across the full breath of the natural hazard scientific community, from those in real-time analysis of natural hazards to those in the research community from academia and government. Key themes and highlights include: Substantial breadth and depth of analysis in terms of the types of natural hazards addressed, the disciplinary perspectives represented, and the number of studies included Targeted, application-centered analyses with a focus on development and use of modeling techniques to address various sources of uncertainty Emphasis on the impacts of climate change on natural hazard processes and outcomes Recommendations for cross-disciplinary and science transfer across natural hazard sciences This volume will be an excellent resource for those interested in the current work on uncertainty classification/quantification and will document common and emergent research themes to allow all to learn from each other and build a more connected but still diverse and ever growing community of scientists.

Die nat?rliche Evolution zunehmender Sozialit?t im Tierreich erkl?rt, warum sich manche Tiere und viele Jetzt-Menschen oft kooperativ, hilfsbereit, solidarisch, sogar altruistisch gegen?ber Artgenossen verhalten, bei generellem Eigennutz der Individuen. Nat?rliche Sozialverb?nde von W?lfen, afrikanischen Wildhunden und Insekten beweisen die Wirkungen biologischer Gesetzm??igkeiten bei der Entstehung sozialer Spezies. An lockerer Vergesellschaftung hemisozialer Wolfsrudel wird das ebenso beobachtet wie bei zwanghafter Eusozialit?t von Insektenstaaten. Die Wirkungen sozialer Evolution bei Hundeartigen und Ameisen sind mit Bezug zum Sozialleben des Jetzt-Menschen beschrieben. Mittels reflektierender Urteilskraft (nach Kant) l?sst sich daraus abduktiv schlussfolgern, warum egalit?re Gemeinschaften ohne Hierarchien nirgends auf Dauer verwirklicht wurden. Die evolutionsbiologischen Erkl?rungen versuchen erkennbar zu machen, warum Egalit? und Demokratie nicht einmal bei humanistisch aufgekl?rten Jetzt-Menschen von selbst entstehen. Sozialistische Verstaatlichung, Aufhebung des Privateigentums an Produktionsmitteln allein, ergab nirgends egalit?re Gesellschaften. Sozialverb?nde mit flachen, durchl?ssigen Hierarchien entstehen nur durch bewusstes Handeln, aufgrund von Mitgef?hl f?r Andere und sozio-?konomischen Strukturen zur Einschr?nkung immer wirksamer Naturfaktoren.

Naturphilosophie der Ern?hrung ist ein popul?rwissenschaftliches Werk, das objektive Tatsachen und subjektive Erfahrungen so vermengt, dass sie eine biologisch stimmige und ?sthetische Lebenspraxis begr?nden. Der R?ckgriff auf vern?nftig belegte aber dennoch kontroverse umstrittene Thesen und Fakten ist dabei unvermeidbar – weil Nahrungsmittel- und Pharmaindustrie ganz gro?es Gesch?ft sind. Die industrielle Verarbeitung von (Feld)Fr?chten resultiert in Nahrungsmittelextrakten, wie zum Beispiel Zucker, Wei?mehl, Pflanzen?le, Proteinpulver. Essen, das solche Extrakte enth?lt, t?uscht den Essinstinkt, der entscheidend auf Geruch und Geschmack beruht. Der Essinstinkt funktioniert auch beim modernen Menschen der Industriegesellschaft zuverl?ssig, aber nur solange wie die Nahrung vollwertig ist. Nahrungsmittelextrakte haben die nat?rliche Balance der N?hrstoffe verloren. Die T?uschung des Essinstinkts f?hrt zu vermehrter und zu falscher Nahrungsaufnahme. Das Buch erkl?rt die resultierende Anf?lligkeit f?r subklinische, akute und chronische Erkrankungen. Neu im Genre der Di?tratgeber ist die ungezwungene Einf?hrung in die formale Chemie der Nahrungsmittel. Ihre Strukturformeln bestimmen Denken und Zielsetzung in der Nahrungsmittelindustrie, und bilden ihr wissenschaftliches Medusenhaupt. Sich nicht l?nger vor ihnen mit Grauen abzuwenden, sondern ihnen mit Verst?ndnis und Interesse standzuhalten, hei?t der Medusa den Kopf abzuschlagen. Formales Verst?ndnis f?r Naturstoffe bef?higt zur Informationsbeschaffung, Kritikf?higkeit und Selbstsicherheit, um biologische Erfordernisse und pathogene Vorg?nge autonom beurteilen zu k?nnen. Es erlaubt den Ausgang aus di?tetischer Unm?ndigkeit und propagandistischer Bevormundung. Zuversichtliches Verstehen und Handeln im Sinne lokaler vorindustrieller (traditioneller) Ern?hrung befreit von Zukunfts?ngsten und Stationierung in Krankenh?usern und Pflegeheimen.

A practical guide to network meta-analysis with examples and code In the evaluation of healthcare, rigorous methods of quantitative assessment are necessary to establish which interventions are effective and cost-effective. Often a single study will not provide the answers and it is desirable to synthesise evidence from multiple sources, usually randomised controlled trials. This book takes an approach to evidence synthesis that is specifically intended for decision making when there are two or more treatment alternatives being evaluated, and assumes that the purpose of every synthesis is to answer the question “for this pre-identified population of patients, which treatment is ‘best’?” A comprehensive, coherent framework for network meta-analysis (mixed treatment comparisons) is adopted and estimated using Bayesian Markov Chain Monte Carlo methods implemented in the freely available software WinBUGS. Each chapter contains worked examples, exercises, solutions and code that may be adapted by readers to apply to their own analyses. This book can be used as an introduction to evidence synthesis and network meta-analysis, its key properties and policy implications. Examples and advanced methods are also presented for the more experienced reader. Methods used throughout this book can be applied consistently: model critique and checking for evidence consistency are emphasised. Methods are based on technical support documents produced for NICE Decision Support Unit, which support the NICE Methods of Technology Appraisal. Code presented is also the basis for the code used by the ISPOR Task Force on Indirect Comparisons. Includes extensive carefully worked examples, with thorough explanations of how to set out data for use in WinBUGS and how to interpret the output. Network Meta-Analysis for Decision Making will be of interest to decision makers, medical statisticians, health economists, and anyone involved in Health Technology Assessment including the pharmaceutical industry.

La verdadera historia de c?mo nuestro cerebro y nuestro sistema nervioso cambian a lo largo de nuestra vida, con o sin «entrenamiento cerebral». Hace cincuenta a?os, los neurocient?ficos pensaban que un cerebro maduro era algo fijo como una mosca atrapada en ?mbar, incapaz de cambiar. Hoy sabemos que nuestro cerebro y nuestro sistema nervioso cambian a lo largo de nuestra vida. Este concepto de neuroplasticidad ha capturado la imaginaci?n de un p?blico ?vido de superaci?n personal y ha inspirado a innumerables emprendedores de Internet que venden juegos y aplicaciones dudosas para el «entrenamiento cerebral». En este libro, Moheb Costandi ofrece una descripci?n concisa y atractiva de la neuroplasticidad para los lectores en general, describiendo c?mo nuestro cerebro cambia continuamente en respuesta a nuestras acciones y experiencias. Costandi analiza los hallazgos experimentales clave y describe c?mo nuestro pensamiento sobre el cerebro ha ido evolucionando con el tiempo. Explica c?mo cambia durante el desarrollo y la «poda sin?ptica» que tiene lugar antes de la madurez cerebral. Demuestra que los cerebros adultos pueden desarrollar nuevas c?lulas (citando, entre muchos otros estudios, investigaciones que muestran que los canarios machos sexualmente maduros aprenden una nueva canci?n cada a?o). Describe tambi?n el tipo de entrenamiento que puede mejorar la funci?n del cerebro. No son los aparatos y los juegos los que prometen «reconfigurarlo», sino las tareas cognitivas sostenidas como, por ejemplo, aprender un instrumento musical o un nuevo idioma (Costandi tambi?n se?ala que los taxistas de Londres aumentan su materia gris despu?s de un entrenamiento riguroso en las complicadas calles de esa ciudad). Cuenta, adem?s, c?mo los cerebros se compensan despu?s de un derrame cerebral o una lesi?n; describe la adicci?n y el dolor como formas inadaptadas de neuroplasticidad; y considera tambi?n los cambios cerebrales que forman parte de la infancia, la adolescencia, la paternidad y el envejecimiento. Nuestro cerebro est? hecho a medida. La neuroplasticidad est? en la esencia de lo que nos hace humanos.

Mit dem Rauchen aufzuh?ren, sei alles nur Kopfarbeit. Das behaupten diejenigen, die das Laster Rauchen nur mit dem eigenen Willen und Wollen besiegen m?chten. Man muss selbst so ?berzeugt sein, nicht mehr rauchen zu wollen, dass man sein eigenes Handeln quasi in Form einer Eigen-Gehirnw?sche umprogrammiert. Ob das ?berhaupt geht, werden Sie sp?ter erfahren. Andere meinen, jemandem das Rauchen abzugew?hnen, gehe nur durch knallharten Druck und eine Schocktherapie. "Ich gebe Ihnen noch maximal drei Jahre, wenn Sie nicht sofort damit aufh?ren!" Manche schmei?en die restlichen Zigaretten sofort weg und reagieren darauf. Andere sieht man hingegen noch im Rollstuhl mit der Kippe im Mundwinkel, den nahen Tod schon vor Augen. So unterschiedlich sind wir Menschen gestrickt. Der eine reagiert auf leichten Druck, den anderen k?nnen Sie mit nichts umhauen. Er macht es trotzdem – oder gerade deswegen, weil er sich seine letzten Tage nicht auch noch vermiesen lassen m?chte. Aber es gibt auch Menschen , die Druck von au?en brauchen. Der Arzt im wei?en Kittel ist eine Autorit?tsperson. Der glaubt man. Und wenn der einem mit voller Wucht einen solchen Satz vor den Kopf knallt,
dann h?ren wir auf zu rauchen. Das kann funktionieren, braucht aber auch besondere Umst?nde, etwa einen drohenden Infarkt oder gerade einen Asthma-Anfall mit Erstickungs-Tendenz. Dann noch den Satz des Arztes obendrauf, das k?nnte es sein. Die Nikotin-Entw?hnung h?tten Sie ohne diesen Druck nie geschafft.

COMPREHENSIVE COVERAGE OF NONLINEAR PROGRAMMING THEORY AND ALGORITHMS, THOROUGHLY REVISED AND EXPANDED Nonlinear Programming: Theory and Algorithms—now in an extensively updated Third Edition—addresses the problem of optimizing an objective function in the presence of equality and inequality constraints. Many realistic problems cannot be adequately represented as a linear program owing to the nature of the nonlinearity of the objective function and/or the nonlinearity of any constraints. The Third Edition begins with a general introduction to nonlinear programming with illustrative examples and guidelines for model construction. Concentration on the three major parts of nonlinear programming is provided: Convex analysis with discussion of topological properties of convex sets, separation and support of convex sets, polyhedral sets, extreme points and extreme directions of polyhedral sets, and linear programming Optimality conditions and duality with coverage of the nature, interpretation, and value of the classical Fritz John (FJ) and the Karush-Kuhn-Tucker (KKT) optimality conditions; the interrelationships between various proposed constraint qualifications; and Lagrangian duality and saddle point optimality conditions Algorithms and their convergence, with a presentation of algorithms for solving both unconstrained and constrained nonlinear programming problems Important features of the Third Edition include: New topics such as second interior point methods, nonconvex optimization, nondifferentiable optimization, and more Updated discussion and new applications in each chapter Detailed numerical examples and graphical illustrations Essential coverage of modeling and formulating nonlinear programs Simple numerical problems Advanced theoretical exercises The book is a solid reference for professionals as well as a useful text for students in the fields of operations research, management science, industrial engineering, applied mathematics, and also in engineering disciplines that deal with analytical optimization techniques. The logical and self-contained format uniquely covers nonlinear programming techniques with a great depth of information and an abundance of valuable examples and illustrations that showcase the most current advances in nonlinear problems.

Heavy-tailed distributions are typical for phenomena in complex multi-component systems such as biometry, economics, ecological systems, sociology, web access statistics, internet traffic, biblio-metrics, finance and business. The analysis of such distributions requires special methods of estimation due to their specific features. These are not only the slow decay to zero of the tail, but also the violation of Cramer’s condition, possible non-existence of some moments, and sparse observations in the tail of the distribution. The book focuses on the methods of statistical analysis of heavy-tailed independent identically distributed random variables by empirical samples of moderate sizes. It provides a detailed survey of classical results and recent developments in the theory of nonparametric estimation of the probability density function, the tail index, the hazard rate and the renewal function. Both asymptotical results, for example convergence rates of the estimates, and results for the samples of moderate sizes supported by Monte-Carlo investigation, are considered. The text is illustrated by the application of the considered methodologies to real data of web traffic measurements.

An Introduction to Machine Learning in Finance, With Mathematical Background, Data Visualization, and R Nonparametric function estimation is an important part of machine learning, which is becoming increasingly important in quantitative finance. Nonparametric Finance provides graduate students and finance professionals with a foundation in nonparametric function estimation and the underlying mathematics. Combining practical applications, mathematically rigorous presentation, and statistical data analysis into a single volume, this book presents detailed instruction in discrete chapters that allow readers to dip in as needed without reading from beginning to end. Coverage includes statistical finance, risk management, portfolio management, and securities pricing to provide a practical knowledge base, and the introductory chapter introduces basic finance concepts for readers with a strictly mathematical background. Economic significance is emphasized over statistical significance throughout, and R code is provided to help readers reproduce the research, computations, and figures being discussed. Strong graphical content clarifies the methods and demonstrates essential visualization techniques, while deep mathematical and statistical insight backs up practical applications. Written for the leading edge of finance, Nonparametric Finance: • Introduces basic statistical finance concepts, including univariate and multivariate data analysis, time series analysis, and prediction • Provides risk management guidance through volatility prediction, quantiles, and value-at-risk • Examines portfolio theory, performance measurement, Markowitz portfolios, dynamic portfolio selection, and more • Discusses fundamental theorems of asset pricing, Black-Scholes pricing and hedging, quadratic pricing and hedging, option portfolios, interest rate derivatives, and other asset pricing principles • Provides supplementary R code and numerous graphics to reinforce complex content Nonparametric function estimation has received little attention in the context of risk management and option pricing, despite its useful applications and benefits. This book provides the essential background and practical knowledge needed to take full advantage of these little-used methods, and turn them into real-world advantage.

Los cambios tecnol?gicos del ?ltimo siglo han generado un nuevo y disruptivo dominio –el ciberespacio–, el cual no solo est? modificando la vida a nivel individual de las personas, sino tambi?n a nivel macro. Por ello, hoy los organismos responsables de la defensa en distintas partes del mundo, han debido rearticular sus procedimientos y prioridades, al tener que asumir, adem?s de la protecci?n de los dominios tradicionales de tierra, mar y aire, la de este nuevo organismo en plena evoluci?n. Esto es fundamental dado que el ciberespacio se compone –adem?s de informaci?n–, de redes interdependientes por las cuales fluyen y se conectan sistemas como la Internet, las telecomunicaciones, la electr?nica, los sistemas inform?ticos corporativos, los procesadores y los controladores, poniendo todo el funcionamiento de la Tierra en riesgo.
Antes del ciberespacio, los activos pose?an protecci?n f?sica –rejas, muros, galpones–, y se hallaban compartimentados. Hoy, los delincuentes que operan en la Web tienen amplias oportunidades para robar y cometer fraudes. Las barreras de protecci?n suelen ser d?biles y, por contrapartida, los m?todos de ataque son cada vez m?s sofisticados. El presente trabajo ofrece una clasificaci?n y un an?lisis actualizado de c?digos maliciosos basados en ofuscaci?n. Se busca con ello aportar a la producci?n y fortalecimiento de los Sistemas de Gestión de Seguridad de la Información (SGSI) en lo referido a mitigación, mantenci?n y respuesta de los sistemas protegidos.

A balanced guide to the essential techniques for solving elliptic partial differential equations Numerical Analysis of Partial Differential Equations provides a comprehensive, self-contained treatment of the quantitative methods used to solve elliptic partial differential equations (PDEs), with a focus on the efficiency as well as the error of the presented methods. The author utilizes coverage of theoretical PDEs, along with the nu merical solution of linear systems and various examples and exercises, to supply readers with an introduction to the essential concepts in the numerical analysis of PDEs. The book presents the three main discretization methods of elliptic PDEs: finite difference, finite elements, and spectral methods. Each topic has its own devoted chapters and is discussed alongside additional key topics, including: The mathematical theory of elliptic PDEs Numerical linear algebra Time-dependent PDEs Multigrid and domain decomposition PDEs posed on infinite domains The book concludes with a discussion of the methods for nonlinear problems, such as Newton's method, and addresses the importance of hands-on work to facilitate learning. Each chapter concludes with a set of exercises, including theoretical and programming problems, that allows readers to test their understanding of the presented theories and techniques. In addition, the book discusses important nonlinear problems in many fields of science and engineering, providing information as to how they can serve as computing projects across various disciplines. Requiring only a preliminary understanding of analysis, Numerical Analysis of Partial Differential Equations is suitable for courses on numerical PDEs at the upper-undergraduate and graduate levels. The book is also appropriate for students majoring in the mathematical sciences and engineering.

This book studies methods to concretely address inverse problems. An inverse problem arises when the causes that produced a given effect must be determined or when one seeks to indirectly estimate the parameters of a physical system. The author uses practical examples to illustrate inverse problems in physical sciences. He presents the techniques and specific methods chosen to solve inverse problems in a general domain of application, choosing to focus on a small number of methods that can be used in most applications. This book is aimed at readers with a mathematical and scientific computing background. Despite this, it is a book with a practical perspective. The methods described are applicable, have been applied, and are often illustrated by numerical examples.

A new edition of this classic work, comprehensively revised to present exciting new developments in this important subject The study of numerical methods for solving ordinary differential equations is constantly developing and regenerating, and this third edition of a popular classic volume, written by one of the world’s leading experts in the field, presents an account of the subject which reflects both its historical and well-established place in computational science and its vital role as a cornerstone of modern applied mathematics. In addition to serving as a broad and comprehensive study of numerical methods for initial value problems, this book contains a special emphasis on Runge-Kutta methods by the mathematician who transformed the subject into its modern form dating from his classic 1963 and 1972 papers. A second feature is general linear methods which have now matured and grown from being a framework for a unified theory of a wide range of diverse numerical schemes to a source of new and practical algorithms in their own right. As the founder of general linear method research, John Butcher has been a leading contributor to its development; his special role is reflected in the text. The book is written in the lucid style characteristic of the author, and combines enlightening explanations with rigorous and precise analysis. In addition to these anticipated features, the book breaks new ground by including the latest results on the highly efficient G-symplectic methods which compete strongly with the well-known symplectic Runge-Kutta methods for long-term integration of conservative mechanical systems. This third edition of Numerical Methods for Ordinary Differential Equations will serve as a key text for senior undergraduate and graduate courses in numerical analysis, and is an essential resource for research workers in applied mathematics, physics and engineering.

Mark H.A. Davis introduced the Piecewise-Deterministic Markov Process (PDMP) class of stochastic hybrid models in an article in 1984. Today it is used to model a variety of complex systems in the fields of engineering, economics, management sciences, biology, Internet traffic, networks and many more. Yet, despite this, there is very little in the way of literature devoted to the development of numerical methods for PDMDs to solve problems of practical importance, or the computational control of PDMPs. This book therefore presents a collection of mathematical tools that have been recently developed to tackle such problems. It begins by doing so through examples in several application domains such as reliability. The second part is devoted to the study and simulation of expectations of functionals of PDMPs. Finally, the third part introduces the development of numerical techniques for optimal control problems such as stopping and impulse control problems.
