Asymptotic Methods for Engineers
by Jan Awrejcewicz Igor V. AndrianovAsymptotic Methods for Engineers is based on the authors’ many years of practical experience in the application of asymptotic methods to solve engineering problems.This book is devoted to modern asymptotic methods (AM), which is widely used in engineering, applied sciences, physics, and applied mathematics. Avoiding complex formal calculations and justifications, the book’s main goal is to describe the main ideas and algorithms. Moreover, not only is there a presentation of the main AM, but there is also a focus on demonstrating their unity and inseparable connection with the methods of summation and asymptotic interpolation.The book will be useful for students and researchers from applied mathematics and physics and of interest to doctoral and graduate students, university and industry professors from various branches of engineering (mechanical, civil, electro-mechanical, etc.).
Asymptotic Multiple Scale Method in Time Domain: Multi-Degree-of-Freedom Stationary and Nonstationary Dynamics
by Jan Awrejcewicz Roman Starosta Grażyna Sypniewska-KamińskaThis book offers up novel research which uses analytical approaches to explore nonlinear features exhibited by various dynamic processes. Relevant to disciplines across engineering and physics, the asymptotic method combined with the multiple scale method is shown to be an efficient and intuitive way to approach mechanics. Beginning with new material on the development of cutting-edge asymptotic methods and multiple scale methods, the book introduces this method in time domain and provides examples of vibrations of systems. Clearly written throughout, it uses innovative graphics to exemplify complex concepts such as nonlinear stationary and nonstationary processes, various resonances and jump pull-in phenomena. It also demonstrates the simplification of problems through using mathematical modelling, by employing the use of limiting phase trajectories to quantify nonlinear phenomena. Particularly relevant to structural mechanics, in rods, cables, beams, plates and shells, as well as mechanical objects commonly found in everyday devices such as mobile phones and cameras, the book shows how each system is modelled, and how it behaves under various conditions. It will be of interest to engineers and professionals in mechanical engineering and structural engineering, alongside those interested in vibrations and dynamics. It will also be useful to those studying engineering maths and physics.
Asymptotical Mechanics of Composites: Modelling Composites without FEM (Advanced Structured Materials #77)
by Jan Awrejcewicz Igor V. Andrianov Vladyslav V. DanishevskyyIn this book the authors show that it is possible to construct efficient computationally oriented models of multi-parameter complex systems by using asymptotic methods, which can, owing to their simplicity, be directly used for controlling processes arising in connection with composite material systems. The book focuses on this asymptotic-modeling-based approach because it allows us to define the most important out of numerous parameters describing the system, or, in other words, the asymptotic methods allow us to estimate the sensitivity of the system parameters. Further, the book addresses the construction of nonlocal and higher-order homogenized models. Local fields on the micro-level and the influence of so-called non-ideal contact between the matrix and inclusions are modeled and investigated. The book then studies composites with non-regular structure and cluster type composite conductivity, and analyzes edge effects in fiber composite materials. Transition of load from a fiber to a matrix for elastic and viscoelastic composites, various types of fiber composite fractures, and buckling of fibers in fiber-reinforced composites is also investigated. Last but not least, the book includes studies on perforated membranes, plates, and shells, as well as the asymptotic modeling of imperfect nonlinear interfaces.
Asynchronous Control for Networked Systems
by María Guinaldo Losada Francisco Rodríguez Rubio Sebastián Dormido BencomoThis book sheds light on networked control systems; it describes different techniques for asynchronous control, moving away from the periodic actions of classical control, replacing them with state-based decisions and reducing the frequency with which communication between subsystems is required. The text focuses specially on event-based control. Split into two parts, Asynchronous Control for Networked Systems begins by addressing the problems of single-loop networked control systems, laying out various solutions which include two alternative model-based control schemes (anticipatory and predictive) and the use of H2/H∞ robust control to deal with network delays and packet losses. Results on self-triggering and send-on-delta sampling are presented to reduce the need for feedback in the loop. In Part II, the authors present solutions for distributed estimation and control. They deal first with reliable networks and then extend their results to scenarios in which delays and packet losses may occur. The novel results presented in Asynchronous Control for Networked Systems are transmitted in a concise and clear style supported by simulation and experimental examples. Some applications are also provided. Academic researchers and graduate students investigating control theory, control engineering and computer communications systems can use this monograph to learn how asynchronous control helps tackle the problems of networked systems in centralized and distributed schemes. Control practitioners at work in power systems, vehicle coordination and traffic networks will also find this book helpful in improving the performance of their systems.
Asynchronous Machines: Basic Calculation Elements from Field Equations
by Valentin AsanbayevThis book attempts to eliminate the existing “imbalance” between the theory of electric machines and the theory of electromagnetic fields. In order to develop viable methods for engineering calculations, the author applies field equations. The resulting, new methods consist of traditional calculation elements represented in a refined form (circuit-loops, parameters, equivalent circuits and voltage equations). These calculation methods should be effective both for researchers and engineering practitioners, especially, in relation to the modern electric machines, such as powerful turbine generators, large high-speed synchronous motors, etc.
Asynchronous On-Chip Networks and Fault-Tolerant Techniques
by Wei Song Guangda ZhangAsynchronous On-Chip Networks and Fault-Tolerant Techniques is the first comprehensive study of fault-tolerance and fault-caused deadlock effects in asynchronous on-chip networks, aiming to overcome these drawbacks and ensure greater reliability of applications. As a promising alternative to the widely used synchronous on-chip networks for multicore processors, asynchronous on-chip networks can be vulnerable to faults even if they can deliver the same performance with much lower energy and area compared with their synchronous counterparts – faults can not only corrupt data transmission but also cause a unique type of deadlock. By adopting a new redundant code along with a dynamic fault detection and recovery scheme, the authors demonstrate that asynchronous on-chip networks can be efficiently hardened to tolerate both transient and permanent faults and overcome fault-caused deadlocks. This book will serve as an essential guide for researchers and students studying interconnection networks, fault-tolerant computing, asynchronous system design, circuit design and on-chip networking, as well as for professionals interested in designing fault-tolerant and high-throughput asynchronous circuits.

At the Base of the Giant's Throat: The Past and Future of America's Great Dams
by Anthony R. PalumbiThere are ninety thousand registered dams in the United States, fifty thousand of them classified as &“major.&” Nearly all of this infrastructure was built during a forty-year period, from 1932 to 1972, in an era of public investment and political consensus that seems inconceivable today. These incredible structures—sometimes called the American Pyramids—helped the country rebound from the Great Depression, brought water and electricity to enormous reaches, helped win World War II for the Allies, and became the basis for decades of prosperous stability.At the Base of the Giant&’s Throat dives into the history of dam-building in the United States as natural waterscapes have been replaced with engineered environments and the bone-dry West became America&’s produce aisle. From the Folsom Powerhouse cranking sixty-hertz alternating current in the 1890s to the iconic Hoover Dam and the gargantuan Grand Coulee Dam, Anthony R. Palumbi lays out how dams and water projects changed the North American continent forever and laid the groundwork for an age of unprecedented prosperity. He also describes how institutional complacency corrupted the ethos of public power and public works—and how the influence of rich landowners undermined the credibility of that ethos. Palumbi shows how our nation&’s ability to cope with natural disasters has been fatally compromised by underinvestment in decaying infrastructure. He argues that a livable future demands investment on a scale few Americans currently grasp. To win that future we must interrogate the history of our most vital public works: the dams, canals, and levees helping to channel life&’s most precious molecule.At the Base of the Giant&’s Throat tells the story of America through its water, sweeping across five hundred years of history, from the swashbuckling exploits of French colonist Samuel de Champlain to the nightmarish urban flooding of Hurricane Katrina and Hurricane Sandy.
At the Coalface: My life as a miner's wife
by Catherine Paton BlackGrowing up in a mining family, Cath's husband Doug promised his father he wouldn't follow in his dangerous footsteps. But after struggling with terrible poverty in 1970s Scotland, Doug decided a pit job would provide his wife and young family much needed security, despite extraordinary risks to life and limb. Every day, Cath kissed her husband goodbye, not knowing if she'd see him again as he went to work at the coalface. And while her husband toiled deep below, the mother-of-five put her cooking and cleaning skills to use in the colliery canteen. In good times and bad, the miner's wives pulled together as much as their men underground. Then Thatcher swept to power and suddenly loyalties were tested and a fight for survival of a different kind ensued. One for their very existence.

Atari Age: The Emergence of Video Games in America
by Michael Z. NewmanBeginning with the release of the Magnavox Odyssey and Pong in 1972, video games, whether played in arcades and taverns or in family rec rooms, became part of popular culture, like television. In fact, video games were sometimes seen as an improvement on television because they spurred participation rather than passivity. These "space-age pinball machines" gave coin-operated games a high-tech and more respectable profile. In Atari Age, Michael Newman charts the emergence of video games in America from ball-and-paddle games to hits like Space Invaders and Pac-Man, describing their relationship to other amusements and technologies and showing how they came to be identified with the middle class, youth, and masculinity.Newman shows that the "new media" of video games were understood in varied, even contradictory ways. They were family fun (but mainly for boys), better than television (but possibly harmful), and educational (but a waste of computer time). Drawing on a range of sources -- including the games and their packaging; coverage in the popular, trade, and fan press; social science research of the time; advertising and store catalogs; and representations in movies and television -- Newman describes the series of cultural contradictions through which the identity of the emerging medium worked itself out. Would video games embody middle-class respectability or suffer from the arcade's unsavory reputation? Would they foster family togetherness or allow boys to escape from domesticity? Would they make the new home computer a tool for education or just a glorified toy? Then, as now, many worried about the impact of video games on players, while others celebrated video games for familiarizing kids with technology essential for the information age.

Atlantic Cod: A Bio-Ecology
by George A. RoseA comprehensive handbook, covering all aspects of the Atlantic cod including the biology, ecology, life histories, behaviour, commercial exploitation and conservation Not only is Atlantic cod one of the most valuable food fish in the world’s oceans, it is an important component of North Atlantic ecosystems and has been subject to much research into its biology, ecology and exploitation. After hundreds of years of exploitation, overfishing in the last half of the 20th Century caused many stocks to collapse, most famously the Northern cod stock off Newfoundland and Labrador, Canada. Since then, most cod stocks have been better researched and managed, but remain in a variety of states, from fully recovered to continued decline. This book, written by world experts, describes that research and management, and the importance of cod and its fisheries on North Atlantic cultures and economies, with impacts well beyond the range of the species. Atlantic Cod: Bio-Ecology of the Fish offers insightful chapter coverage of cod nomenclature, taxonomy, phylogeny and morphology; physiology and ecophysiology; reproduction and spawning behavior; early life history and pre-recruitment processes; migrations, movements and stock identity; feeding, growth and energetics; the place of cod in the ecosystem; the exploitation of cod through history and present day commercial fisheries and precautionary management for sustainable fisheries; impacts of climate change on cod biology and ecology; and the future of the species and its fisheries. Discusses the major commercial importance of Atlantic cod through history Provides a comprehensive treatment of the bio-ecology of the most researched and highly exploited fully marine species Examines how the decline (and recovery) of cod stocks is of great political and scientific interest An essential purchase for marine fisheries scientists Atlantic Cod: Bio-Ecology of the Fish is a vital book for all fisheries scientists, managers and fish biologists.

Atlantic Salmon In Maine
by Committee on Atlantic Salmon in MaineBecause of the pervasive and substantial decline of Atlantic salmon populations in Maine over the past 150 years, and because they are close to extinction, a comprehensive statewide action should be taken now to ensure their survival. The populations of Atlantic salmon have declined drastically, from an estimated half million adult salmon returning to U. S. rivers each year in the early 1800s to perhaps as few as 1,000 in 2001. The report recommends implementing a formalized decision-making approach to establish priorities, evaluate options and coordinate plans for conserving and restoring the salmon.

Atlas of AI: Power, Politics, and the Planetary Costs of Artificial Intelligence
by Kate CrawfordThe hidden costs of artificial intelligence, from natural resources and labor to privacy, equality, and freedom&“Eloquent, clear and profound—this volume is a classic for our times. It draws our attention away from the bright shiny objects of the new colonialism through elucidating the social, material and political dimensions of Artificial Intelligence.&”—Geoffrey C. Bowker, University of California, Irvine What happens when artificial intelligence saturates political life and depletes the planet? How is AI shaping our understanding of ourselves and our societies? In this book Kate Crawford reveals how this planetary network is fueling a shift toward undemocratic governance and increased racial, gender, and economic inequality. Drawing on more than a decade of research, award‑winning science, and technology, Crawford reveals how AI is a technology of extraction: from the energy and minerals needed to build and sustain its infrastructure, to the exploited workers behind &“automated&” services, to the data AI collects from us. Rather than taking a narrow focus on code and algorithms, Crawford offers us a political and a material perspective on what it takes to make artificial intelligence and where it goes wrong. While technical systems present a veneer of objectivity, they are always systems of power. This is an urgent account of what is at stake as technology companies use artificial intelligence to reshape the world.

Atlas of Cilia Bioengineering and Biocomputing
by Richard Mayne Jaap Den ToonderCilia are microscopic finger-like cell-surface organelles possessed by a great many eukaryotic organisms, including humans, whose purposes include generating local fluid movements via rhythmic whip-like beating and environmental sensing. Despite intense research efforts since their discovery by van Leeuwenhoek in the 1670's, several key questions regarding ciliary functions, experimental manipulation and in silico imitation remain unanswered. Major justifications for cilia research lie in their involvement in various forms of human disease (ciliopathies) and their ability to instantiate decentralised, asynchronous sensorial-actuation of adjacent matter through modulation of beating characteristics. Further elucidation of these characteristics, which is a problem requiring the combined expertise of mathematicians, computer scientists, engineers and life scientists, will lead to novel biomedical therapies, creation of `smart' actuating surfaces for microfluidics/lab-on-chip applications and a greater understanding of fluid mechanics in real-world scenarios. This lavishly-illustrated anthology presents recent advances in the fields of ciliary investigation, manipulation, emulation, mimesis and modelling from key researchers in their fields: its goal is to explain the state-of-the-art in cilia bioengineering and bio-computation in a uniquely creative, accessible manner, towards encouraging further transdisciplinary work in the field as well as educating a broad spectrum of scientists and lay people. The volume is split into three distinct but interwoven themes:Biology: Biological preliminaries for the study of cilia; the state-of-the-art in genetic engineering of ciliated cells for biomedical purposes; reprogramming of cilia dynamics in live cells.Engineering: Creation of macro cilia robots for object sorting applications; pneumatic cilia for the optimization of fluid motion; electrostatic, magnetic and MEMS cilia for microfluidic mixing; reviews in artificial cilia fabrication, actuation and flow induction methods.Numerical and computational modelling. Analyses of thin film cilia for `lab on chip' microfluidic mixing applications; modelling of gel-based artificial cilia towards simulating dynamic behaviors of responsive cilia layers in complex fluids across a wide range of potential applications.
