Efficiency Evaluation of Energy Systems
by Mehmet Kanoğlu Ibrahim Dincer Yunus A. ÇengelEfficiency is one of the most frequently used terms in thermodynamics, and it indicates how well an energy conversion or process is accomplished. Efficiency is also one of the most frequently misused terms in thermodynamics and is often a source of misunderstanding. This is because efficiency is often used without being properly defined first. This book intends to provide a comprehensive evaluation of various efficiencies used for energy transfer and conversion systems including steady-flow energy devices (turbines, compressors, pumps, nozzles, heat exchangers, etc.), various power plants, cogeneration plants, and refrigeration systems. The book will cover first-law (energy based) and second-law (exergy based) efficiencies and provide a comprehensive understanding of their implications. It will help minimize the widespread misuse of efficiencies among students and researchers in energy field by using an intuitive and unified approach for defining efficiencies. The book will be particularly useful for a clear understanding of second law (exergy) efficiencies for various systems. It may serve as a reference book to the researchers in energy field. The definitions and concepts developed in the book will be explained through illustrative examples.
Efficiency in Complex Systems: Self-Organization Towards Increased Efficiency (Springer Proceedings in Complexity)
by Georgi Yordanov Georgiev Mahmoud Shokrollahi-FarThis book uses new ideas and language for understanding how self-organization and complexity trend toward increased efficiency. Different measures for efficiency from multiple disciplines are used to probe the ones that provide the most insight. One major goal is to seek a common framework to trace the increase of efficiency as a measure of the level of organization and evolutionary stage of a complex system. The chapters come from a satellite meeting hosted at the Conference on Complex Systems, in Cancun, 2017. The contributions will be peer-reviewed and contributors from outside the conference will be invited to submit chapters to ensure full coverage of the topics. This text will appeal to students and researchers working on complex systems and efficiency.

Efficiency, Sustainability, and Justice to Future Generations
by Klaus MathisFifty years after the famous essay "The Problem of Social Cost" (1960) by the Nobel laureate Ronald Coase, Law and Economics seems to have become the lingua franca of American jurisprudence, and although its influence on European jurisprudence is only moderate by comparison, it has also gained popularity in Europe. A highly influential publication of a different nature was the Brundtland Report (1987), which extended the concept of sustainability from forestry to the whole of the economy and society. According to this report, development is sustainable when it "meets the needs of the present without compromising the ability of future generations to meet their own needs". A key requirement of sustainable development is justice to future generations. It is still a matter of fact that the law as well as the theories of justice are generally restricted to the resolution of conflicts between contemporaries and between people living in the same country. This in turn raises a number of questions: what is the philosophical justification for intergenerational justice? What bearing does sustainability have on the efficiency principle? How do we put a policy of sustainability into practice, and what is the role of the law in doing so? The present volume is devoted to these questions. In Part One, "Law and Economics", the role of economic analysis and efficiency in law is examined more closely. Part Two, "Law and Sustainability", engages with the themes of sustainable development and justice to future generations. Finally, Part Three, "Law, Economics and Sustainability", addresses the interrelationships between the different aspects.
The Efficiency Trap
by Steve HallettThis realistic appraisal of current environmental thinking will challenge environmentalists and industrialists alike. One of the key tenets of the environmental movement is the need for greater efficiency in our use of dwindling natural resources, especially coal, natural gas, and oil. If our products are designed to be more energy efficient, so the thinking goes, our environmental impacts will be reduced and our fossil fuels will last longer. In this surprising new look at sustainability and conservation, environmentalist Steve Hallett argues that this thinking is fundamentally flawed. In fact, based on the example of coal use throughout the Industrial Revolution, more efficiency leads to more consumption, faster depletion of resources, and ultimately more stress on the planet. This is the efficiency trap. How do we avoid this trap? Hallett suggests that we focus on protecting natural resources, ecosystems, and social systems by making them more resilient. Knowing that we have reached limits to growth, we should work to decentralize energy-delivery services to give homes and communities some measure of independence. We can also build more sustainable food systems by diversifying the food-production landscape to address the vulnerabilities of the current supply chain. Efficiency does have its place in specific areas such as recycling and home insulation, but it will not work as a long-term approach to our energy dilemma. Yet recognizing the inevitable limits to our growth and the shortcomings of our current approach to addressing our dwindling resources is a necessary first step toward the establishment of sound environmental policy.

Efficient Cognition: The Evolution of Representational Decision Making
by Armin W. SchulzAn argument that representational decision making is more cognitively efficient, allowing an organism to adjust more easily to changes in the environment. Many organisms (including humans) make decisions by relying on mental representations. Not simply a reaction triggered by perception, representational decision making employs high-level, non-perceptual mental states with content to manage interactions with the environment. A person making a decision based on mental representations, for example, takes a step back from her perceptions at the time to assess the nature of the world she lives in. But why would organisms rely on representational decision making, and what evolutionary benefits does this reliance provide to the decision maker? In Efficient Cognition, Armin Schulz argues that representational decision making can be more cognitively efficient than non-representational decision making. Specifically, he shows that a key driver in the evolution of representational decision making is that mental representations can enable an organism to save cognitive resources and adjust more efficiently to changed environments. After laying out the foundations of his argument—clarifying the central questions, the characterization of representational decision making, and the relevance of an evidential form of evolutionary psychology—Schulz presents his account of the evolution of representational decision making and critically considers some of the existing accounts of the subject. He then applies his account to three open questions concerning the nature of representational decision making: the extendedness of decision making, and when we should expect cognition to extend into the environment; the specialization of decision making and the use of simple heuristics; and the psychological sources of altruistic behaviors.
Efficient Control and Spontaneous Transitions (Springer Theses)
by Miranda LouwerseThis thesis addresses deep questions that cut to the physical and informational essence of central chemical quantities such as transition paths and reaction mechanisms and proposes fundamental new connections between transition-path theory, linear-response theory, nonequilibrium thermodynamics, and information theory. The author investigates slow, energetically efficient driving protocols that drive a system between conformations corresponding to endpoints of a reaction, aiming to find connections between principles of efficient driving and the spontaneous transition mechanism in the absence of driving. First, an alternative perspective of transition-path theory is developed that unifies it with stochastic thermodynamics to describe flows of entropy, energy, and information during the reaction. This also provides an optimization criterion for selecting collective variables. Next, protocols are designed which invert the magnetization of a 3×3 Ising model with minimal energetic cost, and it is determined that using multiple control parameters allows the system to be driven along a fast-relaxing pathway between reaction endpoints. Finally, the author compares these protocols with the spontaneous transition mechanism for magnetization inversion in the same Ising model, finding that designed protocols capture general features of the spontaneous mechanism and energetics given the constraints on the control parameters. This work represents a major step forward in our understanding of rare events and provides a basis for investigating the connection between efficient protocols and spontaneous transition mechanisms which can be further probed in a wider variety of systems.

Efficient High-Order Discretizations for Computational Fluid Dynamics (CISM International Centre for Mechanical Sciences #602)
by Martin Kronbichler Per-Olof PerssonThe book introduces modern high-order methods for computational fluid dynamics. As compared to low order finite volumes predominant in today's production codes, higher order discretizations significantly reduce dispersion errors, the main source of error in long-time simulations of flow at higher Reynolds numbers. A major goal of this book is to teach the basics of the discontinuous Galerkin (DG) method in terms of its finite volume and finite element ingredients. It also discusses the computational efficiency of high-order methods versus state-of-the-art low order methods in the finite difference context, given that accuracy requirements in engineering are often not overly strict. The book mainly addresses researchers and doctoral students in engineering, applied mathematics, physics and high-performance computing with a strong interest in the interdisciplinary aspects of computational fluid dynamics. It is also well-suited for practicing computational engineers who would like to gain an overview of discontinuous Galerkin methods, modern algorithmic realizations, and high-performance implementations.

Efficient Screening Techniques to Identify Mutants with TR4 Resistance in Banana: Protocols
by Joanna Jankowicz-Cieslak Ivan L. IngelbrechtBananas are a staple food for over 500 million people and are also an important cash crop. Fusarium wilt, caused by the fungus Fusarium oxysporum f.sp. cubense, is one of the most destructive diseases of banana globally. Since the 1990s, an aggressive variant of this fungus, called Tropical Race 4 (TR4), severely affected banana plantations in Southeast Asia from where it spread to other continents, including Latin America, where the global banana export market is primarily centred. TR4 is a soil borne pathogen making the disease difficult to contain. The Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture implemented a Coordinated Research Project (CRP) ‘Efficient Screening Techniques to Identify Mutants with Disease Resistance for Coffee and Banana” (2015-2020). This CRP brought together experts from Asia, Europe and Africa in addition to experts of the Joint FAO/IAEA Centre to develop resistance against TR4 through mutation-assisted breeding. Induced mutagenesis is particularly attractive in case of banana since most cultivated bananas are seedless, thus hampering conventional cross breeding.This Open Access book is a compilation of the protocols developed under the CRP specifically for TR4. The first part covers methods for mutation induction, including the integrated use of innovative single-cell culture with mutagenesis techniques. The book also describes up-to-date phenotypic screening methods for TR4 resistance in banana under field-, greenhouse- and laboratory conditions. Finally, molecular and bioinformatics tools for genome-wide mutation discovery following Next Generation Sequencing are also described. Given the imminent threat of Fusarium Wilt TR4 on banana production globally, it is our hope and intention that the book will serve as a timely reference and guide for banana breeders and pathologists worldwide who are committed to the genetic improvement of banana for Fusarium wilt resistance.

Effort: A Behavioral Neuroscience Perspective on the Will
by Jay SchulkinIn Effort: A Behavioral Neuroscience Perspective on the Will, author Jay Schulkin presents a two-fold thesis: there is no absolute separation of the cognitive and non-cognitive brain, and there are diverse cognitive systems, many of which are embodied in motor systems that underlie self-regulation. Central to this thesis is that dopamine is the one neurotransmitter that underlies the diverse senses of effort, and is apparent in most everyday activity, whether solving a problem in our head or moving about. As scientific literature abounds with studies of decision-making and effort, this book emphasizes the importance of demythologizing our understanding of cognitive systems in order to link motivation, behavioral inhibition, self-regulation, and will. Effort will benefit researchers and students in neuroscience, behavioral neuroscience, cognitive psychology, clinical psychology, social psychology, as well as anyone with interest in this topic.
Egg: Nature's Perfect Package
by Steve Jenkins Robin PageHatching a plan for survival isn’t always easy in the wild. And how animals lay, protect, and even use each other's eggs as a food source help reveal the life cycle of the natural world. Eggs come in all shapes and sizes. The ostrich’s is the largest, but some are so small, you need a microscope to spot them. Animals hide them and disguise them in smart and surprising ways, too. Some abandon their eggs, while others protect them fiercely and carry them wherever they go. There are as many kinds of eggs as there are animals that depend on them, because in the animal kingdom, the fight for survival begins with the simple, but extraordinary, egg.
Egg: A Dozen Ovatures
by Lizzie Stark“Endlessly surprising.… Like the egg itself, this book is a perfect, miraculous package.” —Mary Roach, best-selling author of Fuzz An unconventional history of the world’s largest cellular workhorse, from chickens to penguins, from art to crime, and more. The egg is a paradox—both alive and not alive—and a symbol as old as culture itself. In this wide-ranging and delightful journey through its natural and cultural history, Lizzie Stark explores the egg’s deep meanings, innumerable uses, and metabolic importance through a dozen dazzling specimens. From Mali to Finland, mythologies around the globe have invested the egg with powers of regeneration and fecundity, often ascribing the origin of the world to a cosmic egg. An oracle to Romans, fought over by Gold Rush gangs, used as the foundation of the Clown Egg Registry, and blasted into space, the egg has taken on larger proportions than, say, the ovum of an ostrich. It has starred in global dishes from the Korean comfort food ttukbaegi gyeranjjim to the less regaled yet iconic soft-boiled egg. Stark writes a biography of French-born chef Jacques Pépin through his egg creations, and weaves in her personal experiences, like attempting to make the perfect omelet or trying her hand at pysanky—the Ukrainian art of egg decoration. She also explores her fraught relationship to the eggs in her body due to a familial link to cancer, and shares her delight in becoming a mother. Filled with colorful characters and fascinating morsels, Egg is playful, informative, and guarantees that you’ll never take this delicate ovoid for granted again.

The Eggplant Genome (Compendium of Plant Genomes)
by Mark A. ChapmanThe book discusses the importance of eggplant (Solanum melongena L.) as a crop, highlighting the potential for eggplant to serve as a model for understanding several evolutionary and taxonomic questions. It also explores the genomic make-up, in particular in comparison to other Solanaceous crops, and examines the parallels between eggplant and tomato domestication as well as between the most common eggplant species and two related eggplants native to Africa (Ethiopian eggplant [Solanum aethiopicum L.] and African eggplant [Solanum macrocarpon L.]).The eggplant genome was first sequenced in 2014, and an improved version was due to be released in 2017. Further investigations have revealed the relationships between wild species, domesticated eggplant, and feral weedy eggplant (derived from the domesticate), as well as targets of selection during domestication. Parallels between eggplant and tomato domestication loci are well known and the molecular basis is currently being investigated.Eggplant is a source of nutrition for millions of people worldwide, especially in Southeast Asia where it is a staple food source. Domesticated in the old world, in contrast to its congeners tomato and potato, the eggplant is morphologically and nutritionally diverse. The spread of wild eggplants from Africa is particularly interesting from a cultural point of view. This book brings together diverse fields of research, from bioinformatics to taxonomy to nutrition to allow readers to fully understand eggplant’s importance and potential.

The Ego and the Id (Complete Psychological Works Of Sigmund Freud Ser. #0)
by Sigmund Freud“Many major ideas have been borne out [of his theories] and are still relevant today.” —Huffington Post One of famed psychoanalyst Sigmund Freud’s most prominent ideas was that of the id, the ego, and the super-ego—the three main factors behind the workings of the human mind. Freud claimed these components of the human psyche controlled all processes of personality, behaviors, and traits in a person. The Id was a person’s most basic and impulsive instincts—the ones that feed into our deepest desires and physical needs. The Super-Ego was the opposite of the id. This component controlled our highest morals and standards, operating through our conscience and making us desire to be our most ideal-selves. The piece in the middle is the Ego. The ego mediates between the id and realities of the world around us, while being supervised (and guilted) by the super-ego. In this new edition of his book, The Ego and the Id, Sigmund Freud delves deeper into the concepts of the human mind and the results of the conflicts and workings between them.
