Reciprocity, Spatial Mapping and Time Reversal in Electromagnetics
by C. Altman K. SuchyThis long awaited second edition traces the original developments from the 1970s and brings them up to date with new and previously unpublished material to give this work a new lease of life for the early twenty-first century and readers new to the topic. In the winter of 1970-71, Colman Altman had been finding almost exact symmetries in the computed reflection and transmission matrices for plane-stratified magnetoplasmas when symmetrically related directions of incidence were compared. At the suggestion of Kurt Suchy the complex conjugate wave fields, used to construct the eigenmode amplitudes via the mean Poynting flux densities, were replaced by the adjoint wave fields that would propagate in a medium with transposed constitutive tensors, to yield a scattering theorem - reciprocity in k-space -- in the computer output. To prove the result analytically, one had to investigate the properties of the adjoint Maxwell system, and the two independent proofs that followed, in 1975 and 1979, proceeded according to the personal preference of each of the authors. The proof given in this volume, based on the hindsight provided by later results, is much more simple and concise. Later, when media with bianisotropic constitutive tensors were investigated, it was found that conjugate (reciprocal) media and wave fields could be formed by any orthogonal spatial mapping of those in the original problem, after media and fields were reversed in time. The result was still quite general and not limited to stratified systems. The second line of development was to find the link between reciprocity in k-space and Lorentz reciprocity involving currents and sources in physical space. This was done for plane-stratified media by applying the scattering theorem to the plane-wave spectrum of eigenmodes radiated by one current source and reaching the second source. The reverse linkage between Lorentz reciprocity and reciprocity in k-space had already been found. However, this was the first time that the results were presented in a systematic and mathematically well-defined procedure to serve as a tool for solving problems of reciprocity and scattering symmetries. The use of time reversal gives rise to problems of causality when sources are present, but when the interaction between two systems is involved the non-causal effects are irrelevant. The insight gained during these investigations enabled the authors to present many of the earlier theorems and results, both their own and those of others, in a compact and unified approach, which has been the main strength of this book. This new edition has been revised, corrected and updated where necessary to give a complete picture of this interesting topic for the present generation of scientists.
Reckoning with Matter: Calculating Machines, Innovation, and Thinking about Thinking from Pascal to Babbage
by Matthew L. JonesFrom Blaise Pascal in the 1600s to Charles Babbage in the first half of the nineteenth century, inventors struggled to create the first calculating machines. All failed—but that does not mean we cannot learn from the trail of ideas, correspondence, machines, and arguments they left behind. In Reckoning with Matter, Matthew L. Jones draws on the remarkably extensive and well-preserved records of the quest to explore the concrete processes involved in imagining, elaborating, testing, and building calculating machines. He explores the writings of philosophers, engineers, and craftspeople, showing how they thought about technical novelty, their distinctive areas of expertise, and ways they could coordinate their efforts. In doing so, Jones argues that the conceptions of creativity and making they exhibited are often more incisive—and more honest—than those that dominate our current legal, political, and aesthetic culture.

Reclaiming Personalized Learning: A Pedagogy for Restoring Equity and Humanity in Our Classrooms
by Paul Emerich FranceWhere exactly did personalized learning go so wrong? For teacher and consultant Paul France, at first technology-powered personalized learning seemed like a panacea. But after three years spent at a personalized learning start-up and network of microschools, he soon realized that such corporate-driven individualized learning initiatives do more harm than good, especially among our most vulnerable students. The far-superior alternative? A human-centered pedagogy that prioritizes children over technology. First, let’s be clear: Reclaiming Personalized Learning is not yet-another ed tech book. Instead it’s a user’s guide to restoring equity and humanity to our classrooms and schools through personalization. One part polemical, eleven parts practical, the book describes how to: Shape whole-class instruction, leverage small-group interactions, and nurture a student’s inner-dialogue Cultivate awareness within and among students, and build autonomy and authority Design curriculum with a flexible frame and where exactly the standards fit Humanize assessment and instruction, including the place of responsive teaching Create a sense of belonging, humanize technology integration, and effect socially just teaching and learning—all central issues in equity The truth is this: there’s no one framework, there’s no one tool that makes learning personalized–what personalized learning companies with a vested interest in profits might tempt you to believe. It’s people who personalize learning, and people not technology must be at the center of education. The time is now for all of us teachers to reclaim personalized learning, and this all-important book is our very best resource for getting started. “This is a compelling and critically important book for our time. With rich stories of teaching and learning Paul France considers ways to create the most positive learning experiences possible.” - JO BOALER, Nomellini & Olivier Professor of Education, Stanford Graduate School of Education “This brilliant book is a major contribution to the re-imagination of learning and teaching for the twenty-first century and should be essential reading for new and experienced teachers alike." - TONY WAGNER, Senior Research Fellow, Learning Policy Institute “In these troubled times, this book is more than a breath of fresh air, it is a call to action. Paul gives us an accessible and sophisticated book that explains how and why we should celebrate the humanity of every single student.” - JIM KNIGHT, Senior Partner of the Instructional Coaching Group (ICG) and Author of The Impact Cycle

Reclamation of Arid Lands (Environmental Science and Engineering)
by Majid Ghorbani Ehsan Zandi Esfahan Fatemeh Panahi Ali Tavili Mohammad JafariThis book provides an overview of arid and semi-arid lands conditions, their general characteristics, methods of management, conservation, exploitation and reclamation. It also focuses on how to utilize the potential of arid lands with the minimum manipulation and alteration. Arid and semi-arid areas represent a major part of natural ecosystems not only in Iran, but around the world, and mismanagement and inappropriate exploitation of these areas may lead to further gradual degradation. As such, an understanding of the characteristics of these areas is vital if they are to be conserved and reclaimed.
Reclamation of Mine-impacted Land for Ecosystem Recovery
by Colin D. Hills Raj S. Singh Nimisha TripathiMining activities significantly impact the environment; they generate huge quantities of spoil, promote deforestation and the loss of agricultural production, as well as releasing contaminants that result in the loss of valuable soil resources. These negative impacts are now being recognized and this book shows how corrective action can be taken. The introduction of sustainable mining requires mitigation strategies that start during the mine planning stage and extend to after mineral extraction has ceased, and post-closure activities are being executed. Reclamation of Mine-impacted Land for Ecosystem Recovery covers: methods of rejuvenation of mine wasteland including different practices of physical, chemical and ecological engineering methods; benefits of rejuvenation: stabilization of land surfaces; pollution control; aesthetic improvement; general amenity; plant productivity; and carbon sequestration as well as restoring biodiversity and ecosystem function; best management practices and feasible solutions to the impacts of mining which will reduce the pollution load by reducing the discharge rate and the pollutant concentration; reduce erosion and sedimentation problems, and result in improved abandoned mine lands; and ecosystem development. The authors explain how mining impacts on soil properties and how soil carbon reserves/soil fertility can be restored when mining has ceased. Restoration involves a coordinated approach that recognizes the importance of key soil properties to enable re-vegetation to take place rapidly and ecosystems to be established in a low cost and sustainable way. This book's unique combination of the methods for reclamation technologies with policies and best practice worldwide will provide the background and the guidance needed by scientists, researchers and engineers engaged in land reclamation, as well as by industry managers.

Recognition Receptors in Biosensors
by Mohammed ZourobThis book will cover most of the up-to-date recognition receptors technologies used in biosensors. Since this book is written by the world's most renowned and learned scientists in their own area of expertise, we believe that the calibre of the finished product will be as renowned as their reputation. To the best of the editor and author's knowledge this book is a first in this field. We will aim to cover this increasingly hot area of research especially in relation to the new biosensing techniques. Most of the universities are teaching the recognition receptors topics in the Biosensors, separation and Microsystems courses. However, there is no single reference book that covers this interesting area. So the aim of this book is to be a textbook for the undergraduate and graduate student upwards, and an important reference for the professionals working in different fields including biomedical, natural sciences, physical sciences, and nanotechnology, m-TAS, veterinary, food QA, bioterrorism and security as well as health surveillance. The book will cover the different recognition receptors used up-to-date in the different sensing transducer and microarrays platforms. It will cover the background, theory behind each technology, state-of-the-art review for all the new technologies used in biosensing in detail. Strategies and future prospectus are suggested at the end of each chapter for developing future technologies to achieving a better sensitivity, stability and swifter biosensing detection.

Recommendations for Design and Analysis of Earth Structures using Geosynthetic Reinforcements - EBGEO
by the German Geotechnical SocietyThe completely revised and extended Recommendations deal with all questions relevant to the planning and dimensioning of geosynthetics-reinforced earth structures. In addition to the demands on materials and analysis principles, the applications of geosynthetics in a range of foundation systems, ground improvement measures, highways engineering projects, in slopes and retaining structures, and in landfill engineering are discussed. The Recommendations have been supplemented by the following sections: - reinforced earth structures over point or linear bearing elements, - foundation systems using geotextile-encased columns, - bridging subsidence, - dynamic actions of geosynthetic-reinforced systems. The remaining sections have been fundamentally revised and updated in line with current standards and codes of practice.
Recommendations for Fatigue Design of Welded Joints and Components (IIW Collection)
by A. F. HobbacherThis book provides a basis for the design and analysis of welded components that are subjected to fluctuating forces, to avoid failure by fatigue. It is also a valuable resource for those on boards or commissions who are establishing fatigue design codes. For maximum benefit, readers should already have a working knowledge of the basics of fatigue and fracture mechanics. The purpose of designing a structure taking into consideration the limit state for fatigue damage is to ensure that the performance is satisfactory during the design life and that the survival probability is acceptable. The latter is achieved by the use of appropriate partial safety factors. This document has been prepared as the result of an initiative by Commissions XIII and XV of the International Institute of Welding (IIW).

Recommendations of the Committee for Waterfront Structures Harbours and Waterways: EAU 2020
by HTG Deutsche Gesellschaft für GeotechnikThe recommendations have been completely restructured in this 12th (2020) edition of the EAU (10th English edition), the aim being to provide readers with a better, clearer arrangement of the chapters. In addition, the information published in the annual technical reports of the Waterfront Structures Committee since the publication of the 11th German edition have been incorporated in this new edition. The recommendations also take into account the new generation of standards consisting of Eurocode 7, the associated National Application Documents and supplementary national publications (DIN 1054:2010). In isolated instances, partial safety factors differing from those in the codes are specified on the basis of practical experience. Safety standards for ports, harbours and marine structures are therefore upheld. The recommendations satisfy the need for international acceptance in the planning, design, tendering, award of contract, construction, site supervision, acceptance and settlement of accounts for port, harbour and waterway facilities based on uniform approaches.
Recommendations of the Committee for Waterfront Structures Harbours and Waterways EAU 2004
by Mary RudolfSince 1949 the "Committee for Waterfront Structures" has operated on honorary base as a committee of the Society for Harbour Engineering (HTG), Hamburg, and since 1951 also as working group of the German Society for Geotechnics (DGGT), Essen. Its full designation reads "Committee for Simplification an Standardization of Calculation and Construction of Waterfront Structures", which also outlines its goals. Following on from the previous joint publications, this new edition of EAU 2004 contains the safety concept with partial safety factors in accordance with the Eurocodes or the European prestandards as well as with the new edition of the corresponding German standard, partially differing on account of practice experiences. The recommendations continue to satisfy the requirements for international acknowledgement and application with regard to planning, design tendering, the awarding of contracts, building and building supervision. Further, the inspection and accounting procedures for harbour and waterway constructions are given from uniform points of view.
Recommendations of the Committee for Waterfront Structures Harbours and Waterways EAU 2012
by HTGThe "EAU 2012" takes into account the new generation of standards, which is shortly to be introduced into the building control system; it consists of Eurocode 7, the associated national application documents and additional national regulations (DIN 1054:2010). In certain cases, partial safety factors are determined differently based on experience in practice. This means that the safety standard of sea and port buildings remains in place; the recommendations nevertheless satisfy the requirements for international recognition and application regarding the planning, design, specification, tender procedure, construction and monitoring, as well as the handover of - and cost accounting for - port and waterway systems under uniform criteria.
Recommendations on Excavations 3e
by Alan Johnson Deutsche Gesellschaft für Geotechnik e.V. / German Geotechnical SocietyWith the issue of these recommendations, which have the character of a standard, the "Building Excavations" working group of the German Geotechnics Association (DGGT) aims to provide assistance with the design and structural calculation of excavation support works.The introduction of the Eurocodes for building control purposes made necessary a revision of the previous edition of the recommendations to comply with the requirements of DIN EN 1997-1:2009 together with the national annex DIN 1997-1/NA:2010-12 and the supplementary regulations of DIN 1054:2010-12. All recommendations were thoroughly checked, revised where necessary and adapted to new knowledge. Chapter 10 "Building excavations in water" was substantially revised. Due to the progress of development of measurement instruments and the more stringent requirements, Chapter 14 "Instrumentation for the monitoring and supervision of building excavation support works" was formulated completely anew. The recommendations of the working group "Building Excavations" should be of assistance,- to simplify the design and structural calculation of excavation support works,- to harmonise loading assumptions and calculation procedures,- to ensure the structural stability of excavation support works and their individual elements and- to improve the cost-effectiveness of excavation support works.
Recommendations on Piling (EA Pfähle)
by Alan Johnson Deutsche Gesellschaft für Geotechnik e.V. / German Geotechnical SocietyThis handbook provides a complete and detailed overview of piling systems and their application. <P><P>The design and construction of piled foundations is based on Eurocode 7 and DIN 1054 edition 2010 as well as the European construction codes DIN EN 1536 (Bored piles), DIN EN 12699 (Displacement piles) and DIN EN 14199 (Micropiles). These recommendations also deal with - categorisation of piling systems, - actions on piles from structural loading, negative skin friction and side pressure, - pile resistances from static and dynamic pile test loading as well as extensive tables with the pile load-bearing capacity of nearly all piling systems based on values from practical experience, - pile groups, - performance of static and dynamic test loading and integrity tests, - load-bearing behaviour and verifications for piles under cyclical, dynamic and impact actions - quality assurance for construction. An appendix with numerous calculation examples completes the work. As part of the approval procedure for offshore wind energy structures, the Federal Office for Shipping and Hydrography (BSH) demands verifications according to the new Chapter 13 ("Load-bearing behaviour and verifications for piles under cyclical, dynamical and impact actions") of the EA Pfähle (the recommendations of the Piling working group - 2nd edition), which deals with external pile resistance for the foundations of offshore wind energy structures and the types of verifications to be provided under cyclical actions. The publication of the EA-Pfähle recommendations by the Piling working group of the German Society for Geotechnics (DGGT), which works with the same members as the piling standards committee NA 00-05-07, is intended to provide assistance for engineers active in the design, calculation and construction of piled foundations. The recommendations can thus be considered as rules of the technology and as a supplement to the available codes and standards.
