Electromagnetic Properties of Multiphase Dielectrics

Electromagnetic Properties of Multiphase Dielectrics



Recently, several applications, primarily driven by microtechnology, have emerged where the use of materials with tailored electromagnetic (dielectric) properties are necessary for a successful overall design. The “tailored” aggregate properties are achieved by combining an easily moldable base matrix with particles having dielectric properties that are chosen to deliver (desired) effective properties. In many cases, the analysis of such materials requires the simulation of the macroscopic and microscopic electromagnetic response, as well as its resulting coupled thermal response, which can be important to determine possible failures in “hot spots.” This necessitates a stress analysis. Furthermore, because, oftentimes, such processes initiate degratory chemical processes, it can be necessary to also include models for these processes as well. A central objective of this work is to provide basic models and numerical solution strategies to analyze the coupled response of such materials by direct simulation using standard laptop/desktop equipment. Accordingly, this monograph covers: (1) The foundations of Maxwell’s equations, (2) Basic homogenization theory,(3) Coupled systems (electromagnetic, thermal, mechanical and chemical),(4) Numerical methods and(5) An introduction to select biological problems.The text can be viewed as a research monograph suitable for use in an upper-division undergraduate or first year graduate course geared towards students in the applied sciences, mechanics and mathematics that have an interest in the analysis of particulate materials.

The Edge of Reason?

The Edge of Reason?



inspire spiritual wonder? Confrontation between science and religion has defined much public debate about religion in recent years, most lately in bestsellers portraying a clash between scientists and religious believers, such as Richard Dawkins’ ‘The God Delusion ‘and Sam Harris’s ‘The End of Faith ‘or ‘Letter to a Christian Nation.’ But what does this ‘us versus them’ divide mean for society? This collection of essays gives voice to social scientists, natural scientists and theologians whose experience holds direct relevance on these major issues, and clarifies the position of science in the modern debate. Includes contributions by Mary Midgley (University of Newcastle Upon Tyne, UK), Denis Alexander (Cambridge University, UK), Richard Roberts (Lancaster University, UK), Bob Layton (Durham University, UK), Simon Coleman (Sussex University, UK), Michael Shermer (Executive Director of the Sceptics Society and monthly columnist for ‘Scientific American’), Lewis Wolpert (University College London, UK), Andrew Newberg (University of Pennsylvania), Timothy Taylor (University of Bradford, UK), Steven Mithen (University of Reading, UK), David Sloan Wilson (Binghamton University), Herbert Maschner (Idaho State University), Ian Reader (University of Manchester, UK), Hiroko Kawanami (Lancaster University, UK), Andrian Kreye (Suddeutsche Zeitung), John Hedley Brooke (Oxford University, UK), Gordy Slack (Author of ‘The Battle Over The Meaning Of Everything’), Seth Shostak (Seti Institute), William Calvin (University Of Washington), and David Wilkinson (Durham University, UK).

Geothermal Energy

Geothermal Energy



The internal heat of the planet Earth represents an inexhaustible reservoir of thermal energy. This form of energy, known as geothermal energy has been utilized throughout human history in the form of hot water from hot springs. Modern utilization of geothermal energy includes direct use of the heat and its conversion to other forms of energy, mainly electricity. Geothermal energy is a form of renewable energy and its use is associated with very little or no CO2-emissions and its importance as an energy source has greatly increased as the effects of climate change become more prominent. Because of its inexhaustibility it is obvious that utilization of geothermal energy will become a cornerstone of future energy supplies. The exploration of geothermal resources has become an important topic of study as geology and earth science students prepare to meet the demands of a rapidly growing industry, which involves an increasing number professionals and public institutions participating in geothermal energy related projects. This book meets the demands of both groups of readers, students and professionals. Geothermal Energy and its utilization is systematically presented and contains the necessary technical information needed for developing and understanding geothermal energy projects. It presents basic knowledge on the Earths thermal regime and its geothermal energy resources, the types of geothermal energy used as well as its future potential and the perspectives of the industry. Specific chapters of the book deal with borehole heat exchangers and with the direct use of groundwater and thermal water in hydrogeothermal systems. A central topic are Enhanced Geothermal Systems (hot-dry-rock systems), a key technology for energy supply in the near future. Pre-drilling site investigations, drilling technology, well logging and hydraulic test programs are important subjects related to the exploration phase of developing Geothermal Energy sites. The chemical composition of the natural waters used as a heat transport medium in geothermal systems can be used as an exploration tool, but chemistry is also important during operation of a geothermal power plant because of potential scale formation and corrosion of pipes and installations, which needs to be prevented. Graduate students and professionals will find in depth information on Geothermal Energy, its exploration and utilization.

Visualization of Hydrogen-Bond Dynamics

Visualization of Hydrogen-Bond Dynamics



The hydrogen bond represents an important interaction between molecules, and the dynamics of hydrogen bonds in water create an ever-present question associated with the process of chemical and biological reactions. In spite of numerous studies, the process remains poorly understood at the microscopic level because hydrogen-bond dynamics, such as bond rearrangements and hydrogen/proton transfer reactions, are extremely difficult to probe. Those studies have been carried out by means of spectroscopic methods where the signal stems from the ensemble of a system and the hydrogen-bond dynamics were inferred indirectly. This book addresses the direct imaging of hydrogen-bond dynamics within water-based model systems assembled on a metal surface, using a scanning tunneling microscope (STM). The dynamics of individual hydrogen bonds in water clusters, hydroxyl clusters, and water-hydroxyl complexes are investigated in conjunction with density functional theory. In these model systems, quantum dynamics of hydrogen bonds, such as tunneling and zero-point nuclear motion, are observed in real space. Most notably, hydrogen atom relay reactions, which are frequently invoked across many fields of chemistry, are visualized and controlled by STM. This work presents a means of studying hydrogen-bond dynamics at the single-molecule level, providing an important contribution to wide fields beyond surface chemistry.

Air Force Service Procurement

Air Force Service Procurement



To satisfy requirements in the fiscal year 2002 National Defense Authorization Act (U.S. Congress, 2001) to improve the acquisition of services by the Department of Defense, the Air Force established a Program Executive Officer for Combat and Mission Support (AFPEO/CM) who is responsible for management and oversight of a well-defined portfolio of Air Force services acquisition activities. This office is the single point of contact for Air Force services acquisition inquiries and is also responsible for developing long-range plans for cost-effective acquisition of services. To fulfill its responsibilities, the AFPEO/CM needs metrics to help it monitor compliance with statutory requirements, needs to respond to congressional inquiries about specific acquisitions, and needs to effectively manage Air Force services acquisition activities and organizations. RAND Project AIR FORCE was asked to help develop a portfolio of ‘overarching’ measures that will allow the AFPEO/CM to assess the health of Air Force acquisition activities, diagnose problems, and target improvement efforts. This report describes our recommendations. To help develop this portfolio of metrics, we considered the experience of commercial firms, which have long had a ‘strategic’ view of purchasing direct materials (goods) because they are direct inputs to production, but have only recently explored applying such approaches to purchasing services. Through interviews with well-respected chief purchasing officers and other executives involved in service acquisitions, through conference participation, and through a review of the business literature, we found that commercial firms are beginning to manage their service acquisitions in a manner similar to their acquisition of direct materials.

An Economic Analysis of Bilateral Investment Treaties

An Economic Analysis of Bilateral Investment Treaties



Bilateral Investment Treaties (BITs) are an important instrument for the protection of foreign direct investment (FDI). However, compared to international trade law, international investment law has so far received only little research attention from an economic point of view. By applying a law and economics approach, Jan Peter Sasse provides a systematic analysis of the way BITs function. He explains why BITs are more than just a signal, how they relate to institutional competition as well as to institutional quality and why transparency in international investment arbitration is hard to achieve and may even be detrimental.

The De-Mathematisation of Logic

The De-Mathematisation of Logic



This book collects together several articles by the author, to which a certain recent RATIO paper of his relates, with that paper as an introduction to the whole. It displays a major failure in the disposition of the logicians who have followed on from Frege, principally through their attachment to mathematics, and their subsequent neglect of natural language, and its basic grammar. Thus these logicians as a whole have confused, in substantial ways, categories like use with mention, identity with equivalence, predicates with functions, predicates with their nominalisations, sentences with nominals, sentences with propositions, propositions with functions, propositions with sets, properties with states of affairs, direct speech with indirect speech, reference with description, objects with facts, pronouns with nouns, mereological sums with (mathematical) sets, numbers with sets, count terms with mass terms, amounts with numbers, and also units of measure with objects, amongst other things. The book consists in fourteen chapters, with eleven of them being as they have been, or will be, when published in central journals, and other collections. Two further chapters extend the work in another two published papers, while one chapter is quite new. The chapter titles are: ‘Logic and Grammar’, ‘Completing Russell’s Logic’, ‘Logic and Arithmetic’, ‘Natural Language Sets’, ‘Namely Riders: an Update’, ‘Concept and Object in Frege’, ‘Frege’s Hidden Assumption’, ‘A Poor Concept Script’, ‘Motivation by De Se Beliefs’, ‘Out of the Liar Tangle’, ‘Ramseying Liars’, ‘Proving that 2+3=5′, ‘Harmonising Natural Deduction’, and ‘Dialetheias are Mental Confusions’.

Planning and Decision Making for Aerial Robots

Planning and Decision Making for Aerial Robots



This book provides an introduction to the emerging field of planning and decision making for aerial robots. An aerial robot is the ultimate form of Unmanned Aerial Vehicle, an aircraft endowed with built-in intelligence, requiring no direct human control and able to perform a specific task. It must be able to fly within a partially structured environment, to react and adapt to changing environmental conditions and to accommodate for the uncertainty that exists in the physical world. An aerial robot can be termed as a physical agent that exists and flies in the real 3D world, can sense its environment and act on it to achieve specific goals. So throughout this book, an aerial robot will also be termed as an agent.

Philosophy, An Innovative Introduction

Philosophy, An Innovative Introduction



This new book features a unique, engaging approach to introduce students to philosophy. It combines traditional readings and exercises with fictive narratives starring central figures in the history of the field from Plato to Martin Luther King, Jr. The book makes innovative use of compelling short stories from two writers who have prominently combined philosophy and fiction in their work. These narratives illuminate pivotal aspects of the carefully selected classic readings that follow. This gives students two ways to understand the philosophical positions: through indirect argument in fiction and through direct, deductive presentations. Study questions and writing exercises accompany each set of readings and help students grasp the material and create their own arguments.

Essays on Reference, Language, and Mind

Essays on Reference, Language, and Mind



Keith Donnellan is one of the major figures in 20th century philosophy of language and mind, a key member of the highly influential group that altered the course of philosophy of language and mind around 1970. An innovative philosopher, Donnellan’s primary contributions were published in article form rather than books. This volume presents a highly focused collection of articles by Donnellan, beginning with his 1966 groundbreaking ‘Reference and Definite Descriptions,’ historically the first move in the direct reference direction.




Context and the Attitudes Meaning in Context, Volume 1

Context and the Attitudes Meaning in Context, Volume 1



Context and the Attitudes collects thirteen seminal essays by Mark Richard on semantics and propositional attitudes. These essays develop a nuanced account of the semantics and pragmatics of our talk about such attitudes, an account on which in saying what someone thinks, we offer our words as a ‘translation’ or representation of the way the target of our talk represents the world. A broad range of topics in philosophical semantics and the philosophy of mind are discussed in detail, including: contextual sensitivity; pretense and semantics; negative existentials; fictional discourse; the nature of quantification; the role of Fregean sense in semantics; ‘direct reference’ semantics; de re belief and the contingent a priori; belief de se; intensional transitives; the cognitive role of tense; and the prospects for giving a semantics for the attitudes without recourse to properties or possible worlds. Richard’s extensive, newly written introduction gives an overview of the essays. The introduction also discusses attitudes realized by dispositions and other non-linguistic cognitive structures, as well as the debate between those who think that mental and linguistic content is structured like the sentences that express it, and those who see content as essentially unstructured.
