Hard Disk Drive: Mechatronics and Control (Automation and Control Engineering #23)
by Abdullah Al Mamun GuoXiao Guo Chao BiThe hard disk drive is one of the finest examples of the precision control of mechatronics, with tolerances less than one micrometer achieved while operating at high speed. Increasing demand for higher data density as well as disturbance-prone operating environments continue to test designers' mettle. Explore the challenges presented by modern hard disk drives and learn how to overcome them with Hard Disk Drive: Mechatronics and Control.Beginning with an overview of hard disk drive history, components, operating principles, and industry trends, the authors thoroughly examine the design and manufacturing challenges. They start with the head positioning servomechanism followed by the design of the actuator servo controller, the critical aspects of spindle motor control, and finally, the servo track writer, a critical technology in hard disk drive manufacturing. By comparing various design approaches for both single- and dual-stage servomechanisms, the book shows the relative pros and cons of each approach. Numerous examples and figures clarify and illustrate the discussion.Exploring practical issues such as models for plants, noise reduction, disturbances, and common problems with spindle motors, Hard Disk Drive: Mechatronics and Control avoids heavy theory in favor of providing hands-on insight into real issues facing designers every day.
Hard Fighting: Israel in Lebanon and Gaza
by David E. JohnsonLike Israel in 2006, the United States today is likely ill prepared for hybrid warfare. To identify lessons that the U. S. military might learn from the Israeli experience in Lebanon, the author examines the state of the Israeli military before the Second Lebanon War, the lessons it learned during that conflict, the reforms it undertook to address its deficiencies, and how it fared during Operation Cast Lead three years later.
Hard Road West: History and Geology along the Gold Rush Trail
by Keith Heyer MeldahlIn 1848 news of the discovery of gold in California triggered an enormous wave of emigration toward the Pacific. Lured by the promise of riches, thousands of settlers left behind the forests, rain, and fertile soil of the eastern United States in favor of the rough-hewn lands of the American West.
Hard Rock Mine Reclamation: From Prediction to Management of Acid Mine Drainage
by Bruno Bussière Marie GuittonnyHard rock mines have significant effects on the territories where they operate, through both infrastructure construction as well as resource use. Due to their extractive activities, these mines store large quantities of wastes at the surface, which can be both physically and chemically unstable. Reclamation aims to return a mine site to a satisfactory state, meaning that the site should not threaten human health or security, should not generate in the long term any contaminant that could significantly affect the surrounding environment, and should be aesthetically acceptable to communities. This book focuses on the reclamation of waste storage areas, which constitute the main source of pollution during and after mine operations, and especially issues with acid mine drainage and neutral contaminated drainage. Features: Provides fundamental information and describes practical methods to reclaim mine-waste facilities Compares the different methods and illustrates their application at sites through case studies Identifies new reclamation issues and proposes solutions to address them Presents existing and new technologies to reclaim mine waste disposal areas from hard rock mines in different climatic conditions Integrates reclamation into mine operations and long term performance of techniques used through an interdisciplinary approach With mine site reclamation a young and still emerging science, the training needs for professionals and students working in this field are huge. This book is written from an engineering point of view and in it the authors identify new reclamation issues and propose well-tested as well as innovative approaches to addressing them. Students in graduate programs focused on mines and the environment as well as professionals already working in departments related to mine site reclamation will find this book to be a valuable and essential resource.
Hard Talk: When Speech Is Difficult
by Jonathan ColeA moving, patient-centered portrait of the social importance of speech, from a medical expert known for his humanizing explorations of health.Language comes to us through culture, environment, and family. Words embed over time, as we use our minds to comprehend them and then our mouths to say, mean, and own them. Without the ability to speak, or when talking becomes difficult, we face a challenge like few others, forced to reconnect with a world that assumes its communicators are eloquent vocally. In Hard Talk, Jonathan Cole takes a necessary look at the privilege of speech so we can better accommodate those for whom it presents problems. Cole creates space for people with a variety of conditions, including cerebral palsy, vocal cord palsy, cleft palate, Parkinson&’s, and post-stroke aphasia, to describe in their own words what the experience of difficult speech is like. No struggle is the same. Each develops along its own axis of factors—cognitive, social, and physical—that lead to unique vulnerabilities as well as extraordinary moments of adaptation and resilience. One person finds social chatter becoming more problematic than work speech. Another grows alarmed as changes in speech begin to constrain inner thoughts. Some lose the ability to find or make words though they retain awareness, while others lose self-awareness but maintain fluent speech bereft of meaning. One even loses the ability to speak with family while continuing to interact at work.Hard Talk reacquaints us with the social power of speech while affirming the humane value of listening. Cole also reflects on the neuroscientific advances we&’ve made in understanding barriers to speech and how we might reduce them.
Hard Ticks (Acari: A Global Overview
by Alberto A. Guglielmone Richard G. RobbinsTicks of the family Ixodidae, commonly known as hard ticks, occur worldwide and are second only to mosquitoes as vectors of agents pathogenic to humans. Of the 729 currently recognized hard tick species, 283 (39%) have been implicated as human parasites, but the literature on these species is both immense and scattered, with the result that health professionals are often unable to determine whether a particular tick specimen, once identified, represents a species that is an actual or potential threat to its human host. In this book, two leading tick specialists provide a list of the species of Ixodidae that have been reported to feed on humans, with emphasis on their geographical distribution, principal hosts, and the tick life history stages associated with human parasitism. Also included is a discussion of 21 ixodid species that, while having been found on humans, are either not known to have actually fed or may have been misidentified. Additionally, 107 tick names that have appeared in papers on tick parasitism of humans, and that might easily confuse non-taxonomists, are shown to be invalid under the rules of zoological nomenclature. Although the species of ticks that attack humans have long attracted the attention of researchers, few comprehensive studies of these species have been attempted. By gleaning and analyzing the results of over 1,100 scientific papers published worldwide, the authors have provided an invaluable survey of hard tick parasitism that is unprecedented in its scope and detail.
Hard X-Ray Imaging of Solar Flares
by Michele Piana A. Gordon Emslie Anna Maria Massone Brian R. DennisThe idea for this text emerged over several years as the authors participated in research projects related to analysis of data from NASA's RHESSI Small Explorer mission. The data produced over the operational lifetime of this mission inspired many investigations related to a specific science question: the when, where, and how of electron acceleration during solar flares in the stressed magnetic environment of the active Sun.A vital key to unlocking this science problem is the ability to produce high-quality images of hard X-rays produced by bremsstrahlung radiation from electrons accelerated during a solar flare. The only practical way to do this within the technological and budgetary limitations of the RHESSI era was to opt for indirect modalities in which imaging information is encoded as a set of two-dimensional spatial Fourier components. Radio astronomers had employed Fourier imaging for many years. However, differently than for radio astronomy, X-ray images produced by RHESSI had to be constructed from a very limited number of sparsely distributed and very noisy Fourier components. Further, Fourier imaging is hardly intuitive, and extensive validation of the methods was necessary to ensure that they produced images with sufficient accuracy and fidelity for scientific applications.This book summarizes the results of this development of imaging techniques specifically designed for this form of data. It covers a set of published works that span over two decades, during which various imaging methods were introduced, validated, and applied to observations. Also considering that a new Fourier-based telescope, STIX, is now entering its nominal phase on-board the ESA Solar Orbiter, it became more and more apparent to the authors that it would be a good idea to put together a compendium of these imaging methods and their applications. Hence the book you are now reading.

Hard to Break: Why Our Brains Make Habits Stick
by Russell A. PoldrackThe neuroscience of why bad habits are so hard to break—and how evidence-based strategies can help us change our behavior more effectivelyWe all have habits we’d like to break, but for many of us it can be nearly impossible to do so. There is a good reason for this: the brain is a habit-building machine. In Hard to Break, leading neuroscientist Russell Poldrack provides an engaging and authoritative account of the science of how habits are built in the brain, why they are so hard to break, and how evidence-based strategies may help us change unwanted behaviors.Hard to Break offers a clear-eyed tour of what neuroscience tells us about habit change and debunks “easy fixes” that aren’t backed by science. It explains how dopamine is essential for building habits and how the battle between habits and intentional goal-directed behaviors reflects a competition between different brain systems. Along the way, we learn how cues trigger habits; why we should make rules, not decisions; how the stimuli of the modern world hijack the brain’s habit machinery and lead to drug abuse and other addictions; and how neuroscience may one day enable us to hack our habits. Shifting from the individual to society, the book also discusses the massive habit changes that will be needed to address the biggest challenges of our time.Moving beyond the hype to offer a deeper understanding of the biology of habits in the brain, Hard to Break reveals how we might be able to make the changes we desire—and why we should have greater empathy with ourselves and others who struggle to do so.
Hardrock Mining On Federal Lands
by National Research CouncilThis book, the result of a congressionally mandated study, examines the adequacy of the regulatory framework for mining of hardrock minerals--such as gold, silver, copper, and uranium--on over 350 million acres of federal lands in the western United States. These lands are managed by two agencies--the Bureau of Land Management in the Department of the Interior, and the Forest Service in the Department of Agriculture.The committee concludes that the complex network of state and federal laws that regulate hardrock mining on federal lands is generally effective in providing environmental protection, but improvements are needed in the way the laws are implemented and some regulatory gaps need to be addressed. The book makes specific recommendations for improvement, including: The development of an enhanced information management system and a more efficient process to review new mining proposals and issue permits.Changes to regulations that would require all mining operations, other than "casual use" activities that negligibly disturb the environment, to provide financial assurances for eventual site cleanup.Changes to regulations that would require all mining and milling operations (other than casual use) to submit operating plans in advance.

Hardwired: How Our Instincts to Be Healthy are Making Us Sick
by Robert S. Barrett Louis Hugo FrancescuttiFor the first time in a thousand years, Americans are experiencing a reversal in lifespan. Despite living in one of the safest and most secure eras in human history, one in five adults suffers from anxiety as does one-third of adolescents. Nearly half of the US population is overweight or obese and one-third of Americans suffer from chronic pain – the highest level in the world. In the United States, fatalities due to prescription pain medications now surpass those of heroin and cocaine combined, and each year 10% of all students on American college campuses contemplate suicide. With the proliferation of social media and the algorithms for social sharing that prey upon our emotional brains, inaccurate or misleading health articles and videos now move faster through social media networks than do reputable ones. This book is about modern health – or lack of it. The authors make two key arguments: that our deteriorating wellness is rapidly becoming a health emergency, and two, that much of these trends are rooted in the way our highly evolved hardwired brains and bodies deal with modern social change. The co-authors: a PhD from the world of social science and an MD from the world of medicine – combine forces to bring this emerging human crisis to light. Densely packed with fascinating facts and little-told stories, the authors weave together real-life cases that describe how our ancient evolutionary drives are propelling us toward ill health and disease. Over the course of seven chapters, the authors unlock the mysteries of our top health vices: why hospitals are more dangerous than warzones, our addiction to sugar, salt, and stress, our emotionally-driven brains, our relentless pursuit of happiness, our sleepless society, our understanding of risk, and finally, how world history can be a valuable tutor. Through these varied themes, the authors illustrate how our social lives are more of a determinant of health outcome than at any other time in our history, and to truly understand our plight, we need to recognize when our decisions and behavior are being directed by our survival-seeking hardwired brains and bodies.
