From Smart Grids to Smart Cities: New Challenges in Optimizing Energy Grids

by Carlo Alberto Nucci Massimo La Scala S. Lamonaca Sergio Bruno Ugo Stecchi

This book addresses different algorithms and applications based on the theory of multiobjective goal attainment optimization. In detail the authors show as the optimal asset of the energy hubs network which (i) meets the loads, (ii) minimizes the energy costs and (iii) assures a robust and reliable operation of the multicarrier energy network can be formalized by a nonlinear constrained multiobjective optimization problem. Since these design objectives conflict with each other, the solution of such the optimal energy flow problem hasn’t got a unique solution and a suitable trade off between the objectives should be identified. A further contribution of the book consists in presenting real-world applications and results of the proposed methodologies developed by the authors in three research projects recently completed and characterized by actual implementation under an overall budget of about 23 million €.

From Special Relativity to Feynman Diagrams

by Riccardo D'Auria Mario Trigiante

This book, now in its second edition, provides an introductory course on theoretical particle physics with the aim of filling the gap that exists between basic courses of classical and quantum mechanics and advanced courses of (relativistic) quantum mechanics and field theory. After a concise but comprehensive introduction to special relativity, key aspects of relativistic dynamics are covered and some elementary concepts of general relativity introduced. Basics of the theory of groups and Lie algebras are explained, with discussion of the group of rotations and the Lorentz and Poincaré groups. In addition, a concise account of representation theory and of tensor calculus is provided. Quantization of the electromagnetic field in the radiation range is fully discussed. The essentials of the Lagrangian and Hamiltonian formalisms are reviewed, proceeding from systems with a finite number of degrees of freedom and extending the discussion to fields. The final four chapters are devoted to development of the quantum field theory, ultimately introducing the graphical description of interaction processes by means of Feynman diagrams. The book will be of value for students seeking to understand the main concepts that form the basis of contemporary theoretical particle physics and also for engineers and lecturers. An Appendix on some special relativity effects is added.

From Stardust to First Cells: The Origin and Evolution of Early Life

by Sankar Chatterjee

This book presents a groundbreaking hypothesis to answer one of the greatest scientific mysteries: How did life begin? Like a detective piecing together seemingly disparate bits of evidence, Dr. Sankar Chatterjee combines the most recent discoveries in cosmology, geology, chemistry, information systems, and biology, weaving a vast tapestry from the threads of current research. Dr. Chatterjee convincingly argues that the odyssey of life first began when the fundamental building blocks were brought to Earth by meteorites. These cosmic compounds concentrated and simmered like a soup in hydrothermal crater-caldrons. Through a system of subterranean vent networks, a biosynthetic-rich variety of organic compounds mixed and matched into a recipe of rich biomolecules guided by prebiotic information systems. Through symbiosis, these complex biopolymers gradually assemble into membrane-bound protocells. At each stage of this evolutionary progression, through natural selection, they refined with increasing stability and complexity, ultimately leading to the emergence of the first cells about four billion years ago. In this book, Dr. Chatterjee tells this story in rigorous detail in language that is both accessible and engaging.

From Steam to Diesel: Managerial Customs and Organizational Capabilities in the Twentieth-Century American Locomotive Industry (Princeton Studies in Business and Technology)

by Albert Churella

This overview of the leading locomotive producers in the United States during the twentieth century shows how they responded to a radical technological change: the replacement of steam locomotives by diesels. The locomotive industry provides a valuable case study of business practices and dramatic shifts in innovation patterns, since two companies--General Motors and General Electric--that had no traditional ties to locomotive production demolished established steam locomotive manufacturers. Albert Churella uses many previously untapped sources to illustrate how producers responded to technological change, particularly between the 1920s and the 1960s. Companies discussed include the American Locomotive Company (ALCo), the Baldwin Locomotive Works, the Lima Locomotive Works, Fairbanks-Morse, the Electro-Motive Division of General Motors, and General Electric.A comparative work of business history and the history of technology, the book is not a complete history of any locomotive builder, nor does it explore the origins of the diesel engine in great detail. What it does, and does superbly, is to demonstrate how managers addressed radical shifts in technology and production methods. Churella reveals that managerial culture and corporate organizational routines, more than technological competency per se, allowed some companies to succeed, yet constrained the actions of others. He details the shift from small-batch custom manufacturing techniques in the steam locomotive industry to mass-production methods in the diesel locomotive industry. He also explains that chance events and fortuitous technological linkages helped to shape competitive patterns in the locomotive industry.

From Sugar to Splenda

by Bert Fraser-Reid

More than just coincidence connects a Tate & Lyle lawsuit and artificial sweetener to Jamaican-born Chemist Bert Fraser-Reid. From his first experience of Chemistry through his diabetic father, to his determination and drive as a Chemistry student in Canada, Fraser-Reid weaves a remarkable tale integrating science, law and autobiographical anecdotes. This book arises from the lawsuit brought by Tate & Lyle against companies accused of infringing its patents for sucralose, the sweet ingredient in the artificial sweetener SPLENDA which is made by chlorinating sugar. From a 1958 undergraduate intern witnessing the pioneering experiments on sugar chlorination, to being the 1991 recipient of the world's premiere prize for carbohydrate chemistry, Fraser-Reid was groomed for his role as expert witness in the mentioned lawsuit. Nevertheless, it seems more than his career links Fraser-Reid to the case.

From the Earth to the Moon and Around the Moon (The Jules Verne Collection)

by Jules Verne

Gun experts set their sights on shooting a man to the moon in these two novels by Jules Verne—now available together with an arresting new look!In the aftermath of the American Civil War, the members of The Baltimore Gun Club find themselves in a dilemma—without a war, there is no demand for their innovative gun designs. Eager for a new challenge, the club&’s President Barbicane sets an ambitious goal: to build the largest gun in the world, powerful enough to shoot a man to the moon. Such a gun has never been attempted, so the club faces a myriad of challenges including what to make it from, where to build it, when to shoot it, and—most importantly—how to ensure that a passenger inside the gun&’s projectile can survive the trip. In From Earth to the Moon, the members of the gun club undertake the engineering challenge, and Around the Moon follows the three voyagers on their journey to the moon and back.

From the Molecular World

by Hermann Kopp Alan J. Rocke

Hermann Kopp (1817-1892) is best remembered today as a historian of chemistry, but during his lifetime he was one of the most eminent chemists of his day, and one of the earliest pioneers of physical chemistry. Late in his career he wrote an endearing fantasy about personified molecules. Published in 1882, Aus der Molecular-Welt (From the Molecular World) portrayed the intimate details of what might actually be happening in the sub-microscopic world; the atoms and molecules we meet there have agency, personalities, sometimes even dialog. Filled with appealing tropes, humor, and whimsical asides, Kopp's short book provided an examination of the chemistry and physics of his day that was always light-hearted on the surface, but often surprisingly profound. Properly interpreted, the book provides a revealing tour of nineteenth-century debates concerning chemical theory. It is here translated into English, richly annotated, and equipped with an illuminating preface by a leading historian of chemistry. It provides entertaining reading to practicing chemists, as well as new insights to historians of science.

From the Realm of the Nebulae to Populations of Galaxies

by Mauro D'Onofrio Roberto Rampazzo Simone Zaggia

In order to outline possible future directions in galaxy research, this book wants to be a short stopover, a moment of self-reflection of the past century of achievements in this area. Since the pioneering years of galaxy research in the early 20th century, the research on galaxies has seen a relentless advance directly connected to the parallel exponential growth of new technologies. Through a series of interviews with distinguished astronomers the editors provide a snapshot of the achievements obtained in understanding galaxies. While many initial questions about their nature have been addressed, many are still open and require new efforts to achieve a solution. The discussions may reveal paradigms worthwhile revisiting. With the help of some of those scientists who have contributed to it, the editors sketch the history of this scientific journey and ask them for inspirations for future directions of galaxy research.

From the Seashore to the Seafloor: An Illustrated Tour of Sandy Beaches, Kelp Forests, Coral Reefs, and Life in the Ocean's Depths

by Janet Voight

An octopus expert and celebrated artist offer a deep dive to meet the enchanting inhabitants of the world’s marine ecosystems. Have you ever walked along the beach and wondered what kind of creatures can be found beneath the waves? Have you pictured what it would be like to see the ocean not from the shore but from its depths? These questions drive Janet Voight, an expert on mollusks who has explored the seas in the submersible Alvin that can dive some 14,000 feet below the water’s surface. In this book, she partners with artist Peggy Macnamara to invite readers to share her undersea journeys of discovery. With accessible scientific descriptions, Voight introduces the animals that inhabit rocky and sandy shores, explains the fragility of coral reefs, and honors the extraordinary creatures that must search for food in the ocean’s depths, where light and heat are rare. These fascinating insights are accompanied by Macnamara’s stunning watercolors, which illuminate these ecosystems and other scenes from Voight’s research. Together, they show connections between life at every depth—and warn of the threats these beguiling places and their eccentric denizens face.

From the Universe to the Elementary Particles

by Ulrich Ellwanger

In this book, the author leads the reader, step by step and without any advanced mathematics, to a clear understanding of the foundations of modern elementary particle physics and cosmology. He also addresses current and controversial questions on topics such as string theory. The book contains gentle introductions to the theories of special and general relativity, and also classical and quantum field theory. The essential aspects of these concepts are understood with the help of simple calculations; for example, the force of gravity as a consequence of the curvature of the space-time. Also treated are the Big Bang, dark matter and dark energy, as well as the presently known interactions of elementary particles: electrodynamics, the strong and the weak interactions including the Higgs boson. Finally, the book sketches as yet speculative theories: Grand Unification theories, supersymmetry, string theory and the idea of additional dimensions of space-time. Since no higher mathematical or physics expertise is required, the book is also suitable for college and university students at the beginning of their studies. Hobby astronomers and other science enthusiasts seeking a deeper insight than can be found in popular treatments will also appreciate this unique book.

From the Web to the Grid and Beyond

by René Brun Giuliana Galli Carminati Federico Carminati

Born after World War II, large-scale experimental high-energy physics (HEP) has found itself limited ever since by available accelerator, detector and computing technologies. Accordingly, HEP has made significant contributions to the development of these fields, more often than not driving their innovations. The invention of the World Wide Web at CERN is merely the best-known example out of many. This book is the first comprehensive account to trace the history of this pioneering spirit in the field of computing technologies. It covers everything up to and including the present-day handling of the huge demands imposed upon grid and distributed computing by full-scale LHC operations--operations which have for years involved many thousands of collaborating members worldwide and accordingly provide the original and natural testbed for grid computing concepts. This book takes the reader on a guided tour encompassing all relevant topics, including programming languages, software engineering, large databases, the Web, and grid- and cloud computing. The important issue of intellectual property regulations for distributed software engineering and computing is also addressed. Aptly, the book closes with a visionary chapter of what may lie ahead. Approachable and requiring only basic understanding of physics and computer sciences, this book is intended for both education and research.

From This Day Forward: Marriage Equality in Australia

by Rodney Croome

Australia is now the only developed English-speaking country where same-sex couples can't marry. In this timely book, one of Australia's leading marriage equality advocates goes beyond the slogans and sound bites to explain why the nation is debating marriage equality, why the reform matters and how reform can be achieved. Along the way he considers the history of freedom to marry in Australia, what debate on marriage equality reveals about his home state of Tasmania, and how gay identity and marriage have evolved to the point where marriage equality is not only possible but likely.

From A to Bee: My First Year as a Beginner Beekeeper

by James Dearsley

James Dearsley’s wife thought he had lost his mind when he announced his intention to become a beekeeper. Like many interested in self-sufficiency, he loved gardening and growing vegetables and he wanted to teach his little boy where honey came from, so he set himself a goal: to get, in a year’s time, just one jar of honey.

From Tracking Code to Analysis

by Etienne Forest

This book illustrates a theory well suited to tracking codes, which the author has developed over the years. Tracking codes now play a central role in the design and operation of particle accelerators. The theory is fully explained step by step with equations and actual codes that the reader can compile and run with freely available compilers. In this book, the author pursues a detailed approach based on finite "s"-maps, since this is more natural as long as tracking codes remain at the center of accelerator design. The hierarchical nature of software imposes a hierarchy that puts map-based perturbation theory above any other methods. This is not a personal choice: it follows logically from tracking codes overloaded with a truncated power series algebra package. After defining abstractly and briefly what a tracking code is, the author illustrates most of the accelerator perturbation theory using an actual code: PTC. This book may seem like a manual for PTC; however, the reader is encouraged to explore other tools as well. The presence of an actual code ensures that readers will have a tool with which they can test their understanding. Codes and examples will be available from various sites since PTC is in MAD-X (CERN) and BMAD (Cornell).

From Traditional to Modern African Water Management: Lessons for the Future

by Chrispin Kowenje Andreas Haarstrick Timothy Biswick Gideon Ajeagah Stephen Ojwach Oluwatoyin A. Odeku Gnon Baba

This book preserves and scientifically interprets the African foreknowledge on water resources management. It offers insight into the relevance of the traditional knowledge and practices to modern approaches on sustainable water management. The African continent has partially preserved its natural habitat for centuries. In this book, this knowledge is combined with the current scientific understanding. The traditional practices are categorized as: i) water harvesting, ii) water transportation, iii) water storage and conservation, iv) water treatments, v) myths and folk stories about water management or conservation, vi) water resource management systems, and vii) soil–water–forest conservation/management systems sub-topics. The findings presented here are in line with SDG 6, which aims at ensuring availability and sustainable management of water and sanitation for all by the year 2030.

From Transuranic to Superheavy Elements

by Helge Kragh

The story of superheavy elements - those at the very end of the periodic table - is not well known outside the community of heavy-ion physicists and nuclear chemists. But it is a most interesting story which deserves to be known also to historians, philosophers, and sociologists of science and indeed to the general public. This is what the present work aims at. It tells the story or rather parts of the story, of how physicists and chemists created elements heavier than uranium or searched for them in nature. And it does so with an emphasis on the frequent discovery and naming disputes concerning the synthesis of very heavy elements. Moreover, it calls attention to the criteria which scientists have adopted for what it means to have discovered a new element. In this branch of modern science it may be more appropriate to speak of creation instead of discovery. The work will be of interest to scientists as well as to scholars studying modern science from a meta-perspective.

From Ultra Rays to Astroparticles

by Wolfgang Rhode Brigitte Falkenburg

The scope of the book is to give an overview of the history of astroparticle physics, starting with the discovery of cosmic rays (Victor Hess, 1912) and its background (X-ray, radioactivity). The book focusses on the ways in which physics changes in the course of this history. The following changes run parallel, overlap, and/or interact: - Discovery of effects like X-rays, radioactivity, cosmic rays, new particles but also progress through non-discoveries (monopoles) etc. - The change of the description of nature in physics, as consequence of new theoretical questions at the beginning of the 20th century, giving rise to quantum physics, relativity, etc. - The change of experimental methods, cooperations, disciplinary divisions. With regard to the latter change, a main topic of the book is to make the specific multi-diciplinary features of astroparticle physics clear.

From UXD to LivXD: Living eXperience Design

by Sylvie Leleu-Merviel Daniel Schmitt Philippe Useille

Living eXperience Design – the design of life experiences – is an extension of user experience design (UXD). The context comprises usage and practice in real contexts in which spatial, urban, social, temporal, historical and legal dimensions are considered. Reflecting upon LivXD is to examine the whole experience of a target audience in a variety of situations – and not only in those involving digital technology. This book begins with the definition of LivXD and its associated epistemology, and proceeds to detail field experiments in certain privileged areas: the relation to creation and works, mediation and adult education.

From Varying Couplings to Fundamental Physics

by Carlos Martins Paolo Molaro

Nature is characterized by a number of physical laws and fundamental dimensionless couplings. These determine the properties of our physical universe, from the size of atoms, cells and mountains to the ultimate fate of the universe as a whole. Yet it is rather remarkable how little we know about them. The constancy of physical laws is one of the cornerstones of the scientific research method, but for fundamental couplings this is an assumption with no other justification than a historical assumption. There is no 'theory of constants' describing their role in the underlying theories and how they relate to one another or how many of them are truly fundamental. Studying the behaviour of these quantities throughout the history of the universe is an effective way to probe fundamental physics. This explains why the ESA and ESO include varying fundamental constants among their key science drivers for the next generation of facilities. This symposium discussed the state-of-the-art in the field, as well as the key developments anticipated for the coming years.
