The Reference Collection: From the Shelf to the Web
by Linda S KatzStay up-to-date with the growing amount of reference resources available onlineHow important is the World Wide Web to information retrieval and communication? Important enough that information professionals have seen students exit from their libraries en masse when Internet service was lost. Internet providers dominate the indexing and abstracting of periodical articles as major publishers now offer nearly all of their reference titles in digital form. Libraries spend increasing amounts of funding on electronic reference materials, and librarians devote an increasing amount of time to assisting in their use. The Reference Collection: From the Shelf to the Web is an essential guide to collection development for electronic materials in academic and public libraries. The Reference Collection: From the Shelf to the Web tracks the continuing evolution of electronic reference resources-and how they&’re accessed-in a variety of settings. Librarians representing university, elementary school, and public libraries in the United States and Australia examine how reference collections have evolved over time (and may soon be a thing of the past); how public and school libraries have dealt with the changes; why library research assignments have become more difficult for teachers to make and for students to complete; how to organize online reference sources; and why the nature of plagiarism has changed in the electronic era. The book also examines the use of electronic references from a publisher&’s perspective and looks at the most important Web-accessible reference tools-both free and subscription-in the areas of humanities, medicine, the social sciences, business, and education. The Reference Collection: From the Shelf to the Web also examines: issues of authority, accessibility, cost, comfort, and user education in evaluating electronic resources the formation of purchasing consortia to facilitate the transfer of reference materials from print to online formats current literature and research findings on the state of digital versus print reference collections what electronic publishing means to smaller reference books (dictionaries, almanacs, etc.) the need for increased information literacy among students the nature, extent, and causes of cyber plagiarism the use of federated search tools and includes a selected list of the top 100 free Internet reference sitesThe Reference Collection: From the Shelf to the Web is an essential resource for all reference and collection development librarians, and an invaluable aid for publishing professionals.
Reference-Free CMOS Pipeline Analog-to-Digital Converters
by Michael Figueiredo João Goes Guiomar EvansThis book shows that digitally assisted analog to digital converters are not the only way to cope with poor analog performance caused by technology scaling. It describes various analog design techniques that enhance the area and power efficiency without employing any type of digital calibration circuitry. These techniques consist of self-biasing for PVT enhancement, inverter-based design for improved speed/power ratio, gain-of-two obtained by voltage sum instead of charge redistribution, and current-mode reference shifting instead of voltage reference shifting. Together, these techniques allow enhancing the area and power efficiency of the main building blocks of a multiplying digital-to-analog converter (MDAC) based stage, namely, the flash quantizer, the amplifier, and the switched capacitor network of the MDAC. Complementing the theoretical analyses of the various techniques, a power efficient operational transconductance amplifier is implemented and experimentally characterized. Furthermore, a medium-low resolution reference-free high-speed time-interleaved pipeline ADC employing all mentioned design techniques and circuits is presented, implemented and experimentally characterized. This ADC is said to be reference-free because it precludes any reference voltage, therefore saving power and area, as reference circuits are not necessary. Experimental results demonstrate the potential of the techniques which enabled the implementation of area and power efficient circuits.

Refined Ray Tracing inside Single- and Double-Curvatured Concave Surfaces
by Balamati Choudhury Rakesh Mohan JhaThis book describes the ray tracing effects inside different quadric surfaces. Analytical surface modeling is a priori requirement for electromagnetic (EM) analysis over aerospace platforms. Although numerically-specified surfaces and even non-uniform rational basis spline (NURBS) can be used for modeling such surfaces, for most practical EM applications, it is sufficient to model them as quadric surface patches and the hybrids thereof. It is therefore apparent that a vast majority of aerospace bodies can be conveniently modeled as combinations of simpler quadric surfaces, i. e. hybrid of quadric cylinders and quadric surfaces of revolutions. Hence the analysis of geometric ray tracing inside is prerequisite to analyzing the RF build-up. This book, describes the ray tracing effects inside different quadric surfaces such as right circular cylinder, general paraboloid of revolution (GPOR), GPOR frustum of different shaping parameters and the corresponding visualization of the ray-path details. Finally ray tracing inside a typical space module, which is a hybrid of a finite segment of right circular cylinder and a frustum of GPOR is analyzed for practical aerospace applications.
Refined Safety Control of Unmanned Flight Vehicles via Fractional-Order Calculus
by Ziquan Yu Youmin Zhang Bin Jiang Chun-Yi SuThe monograph explores the safety of unmanned flight vehicles via the corresponding fault-tolerant control design methods. The authors analyse the safety control issues of unmanned flight vehicles, which include finite-time recovery against faults, concurrence of actuator faults and sensor faults, concurrence of actuator faults and wind effects, and faults encountered by a portion of unmanned flight vehicles in a distributed communication network. In addition, the commonly used simple but effective proportional-integral-derivative structure is also incorporated into the safety control design for unmanned flight vehicles. By using the fractional-order calculus, the developed safety control results are able to ensure flight safety and achieve the refined performance adjustments against faults and wind effects. The book will be of interest to 3rd/4th year undergraduate students, postgraduate and graduate students, researchers, academic staff, engineers of aircraft and unmanned flight vehicles.

Refining Processes for the Co-Development of Genome-Based Therapeutics and Companion Diagnostic Tests
by Sarah H. BeachyMany drug developers have examined new strategies for creating efficiencies in their development processes, including the adoption of genomics-based approaches. Genomic data can identify new drug targets for both common and rare diseases, can predict which patients are likely to respond to a specific treatment, and has the potential to significantly reduce the cost of clinical trials by reducing the number of patients that must be enrolled in order to demonstrate safety and efficacy. A key component of the approval of targeted therapeutics is the ability to identify the population of patients who will benefit from treatment, and this has largely hinged on the co-development and co-submission to the FDA of a companion diagnostic test. The co-development process, or the development of the test and drug for the simultaneous submission to FDA, has led to a major alteration in the way that drugs are being developed, with traditionally separate entities--pharmaceutical and diagnostic companies--now working in close collaboration. Refining Processes for the Co-Development of Genome-Based Therapeutics and Companion Diagnostic Tests is the summary of a workshop held by the Roundtable on Translating Genomic-Based Research for Health on February 27, 2013 to examine and discuss challenges and potential solutions for the codevelopment of targeted therapeutics and companion molecular tests for the prediction of drug response. Prior to the workshop, key stakeholders, including laboratory and medical professional societies, were individually asked to provide possible solutions to resolve the concerns raised about co-development of companion diagnostic tests and therapies. Workshop speakers were charged with addressing these solutions in their presentations by providing insight on (1) whether the proposed solutions address the problems described, (2) whether there are other solutions to propose, and (3) what steps could be taken to effectively implement the proposed solutions.

Reflections on Power Prediction Modeling of Conventional High-Speed Craft (SpringerBriefs in Applied Sciences and Technology)
by Dejan RadojčićThis SpringerBrief focuses on modeling and power evaluation of high-speed craft. The various power prediction methods, a principal design objective for high-speed craft of displacement, semi-displacement, and planing type, are addressed. At the core of the power prediction methods are mathematical models for resistance and propulsion efficiency. The models are based on the experimental data of various high-speed hull and propeller series. The regression analysis and artificial neural network (ANN) methods are used as an extraction tool for this kind of mathematical models. A variety of mathematical models of this type are discussed in the book.Once these mathematical models have been developed and validated, they can be readily programmed into software tools, thereby enabling the parametric analyses required for the optimization of a high-speed craft design. This book provides the foundational reference for these software tools, and their use in the design of high-speed craft. High-speed craft are very different from conventional ships. Current professional literature leaves a gap in the documentation of best design practices for high-speed craft. This book is aimed at naval architects who design and develop various types of high-speed vessels.
Reflections on Slope Stability Engineering
by Edward N. BromheadSlope stability engineering is both an art and a science practised by many civil and geotechnical engineers involved in work on landslides, earth dams, breakwaters, coastal defence, earthworks slopes for roads, canals, railways, pipelines, housing developments, and other related developments. This book contains the detailed reflections of its author, who has practised and researched in the field for over a half-century. It is written in an informal style that makes it an interesting and thought-provoking practitioner guide to landslides and slope problems and their investigation, analysis, and remediation, considering both natural and man-made slopes and earthworks, and without the need for the usual equations and illustrations. Reflections on Slope Stability Engineering is targeted primarily at practitioners working in the investigations of slope instability and the design and construction of treatments of the problem, especially those early in their careers, but the accessible style also suits students who are developing an interest in the subject and even those engineers with only a casual interest in this branch of geotechnics.
Reflections on the Role of Ethics in Agriculture
by Robert ZimdahlThis volume is an update to Weed Science- A Plea for Thought-Revisited published by Springer in 2012. More than a decade after the first edition, ethical discussion on the use of pesticides for weed management is largely absent. Startingly, weed science and agriculture have continued on the same path and are still dominated by capital chemical and energy intensive practices, including the paralysis of pesticides. This second edition expands upon the first, using recent data to confirm the dominance of herbicides. The revision includes chapters which emphasize the role of ethics in agriculture and the reasons it should, but has not yet become part of agricultural education. This includes suggestions on how education in agricultural ethics should be shifting and whose responsibility it is. The revised version also includes a discussion on the role of genetically modified crops and the consequences of using these crops-both positive and negative. Scientists have developed a wealth of knowledge they bring to the surface of their disciplinary silos. Yet there needs to be greater discussion on the necessity and risks of agricultural science and technology. This revised version provides a rigorous examination of weed science’s goals and ethics and challenges the way we manage weeds and agriculture.
Reflective Assessment for Deep Learning and Knowledge Building: An Empirical Case in China
by Chunlin LeiKnowledge building aims to transform schools into learning communities and bring knowledge creation into schools. The book therefore elaborates on how learning, technology, and assessment can be aligned both online and offline to facilitate such a process.Adopting a quasi-experimental design and drawing on rich data from forum discussions, questionnaires, interviews, learning outcomes, and classroom presentations, this book shows that the knowledge building environment, augmented by reflective assessment and principles, helped Chinese students to develop a deeper approach to learning, improved academic performance, and promoted collective knowledge advances. The book also discusses the potentials and challenges of designing technology-supported, assessment- and principle-based learning environments in tertiary contexts, especially when deep learning and knowledge building capacity are greatly emphasised in the knowledge era.The book will be of interest to scholars and educators working in learning sciences and computer-supported collaborative learning.

Reflektierender Faraday-Effekt-Stromsensor (essentials)
by Reiner ThieleReiner Thiele hat durch die Applikation des Faraday-Effektes zur Polarisations-Ebenen-Drehung linear polarisierten Lichts in Lichtwellenleitern, induziert durch das den stromführenden elektrischen Leiter umgebende Magnetfeld, eine Lösung gefunden, hohe elektrische Ströme ohne Eingriff in den Messgrößenkreis zu messen. Dies stellte bisher ein grundsätzliches Problem der elektrischen Energietechnik dar. Eine in Reflexion arbeitende erfindungsgemäße Schaltungsanordnung aus optischen und elektronischen Komponenten stellt dabei den gewünschten linearen Zusammenhang zwischen Messgröße und Messwert bei Elimination der störenden Doppelbrechung der Lichtwellenleiter her, die sich ansonsten vermindernd auf die Effizienz des Faraday-Effektes auswirkt.
