Active Structural Control with Stable Fuzzy PID Techniques (SpringerBriefs in Applied Sciences and Technology)

by Wen Yu Suresh Thenozhi

This book presents a detailed discussion of intelligenttechniques to measure the displacement of buildings when they are subjected tovibration. It shows how these techniques are used to control active devicesthat can reduce vibration 60-80% more effectively than widely used passiveanti-seismic systems. After introducing various structural control devices andbuilding-modeling and active structural control methods, the authors proposeoffset cancellation and high-pass filtering techniques to solve some commonproblems of building-displacement measurement using accelerometers. The mostpopular control algorithms in industrial settings, PD/PID controllers, are thenanalyzed and then combined with fuzzy compensation. The stability of thiscombination is proven with standard weight-training algorithms. These conditionsprovide explicit methods for selecting PD/PID controllers. Finally, fuzzy-logicand sliding-mode control are applied to the control of wind-induced vibration. The methods described are supported by reports of experimental studies on atwo-story building prototype. This book is avaluable resource for academic researchers interested in the effects of controland mechatronic devices within buildings, or those studying the principles ofvibration reduction. Practicing engineers working on the design andconstruction of any sort of high-rise or vulnerable building and concerned withthe effects of either wind or seismic disturbances benefit from the efficacy ofthe methods proposed.

Active Vibration & Noise Control: A New Paradigm to Active Control

by Jiqiang Wang

The book is motivated by the pivotal issue: what is the performance limit of active control and energy harvesting? It aims to develop systematic design methodologies with a “visualization technique” where the performance limit can be readily determined solely based on visual inspections.Modern technological systems have evolved toward high speed, heavy load, lightweight, flexible operation and extreme conditions, as demonstrated in aerospace, marine, transportation and manufacturing industries. The associated vibration and noise issues have become such problematic that they may significantly confine the performance of the systems, to say the discomfort at least.Through the geometric representation of the performance specifications, fundamental issues such as (1) the existence of feasible controllers; (2) the optimality of controllers; (3) the performance limit of controllers; (4) compromisability among the performance specifications; (5) the synthesis of controllers; and (6) the influence of constraints on optimal solutions can all be resolved within the proposed framework. The state of the art is thus refined with a new approach complementary to those optimization-based routines, where extra effort would have to be exercised to disclose the compromisability of performance specifications.The proposed book will result in a new design methodology—performance limit-oriented active control. It was initiated by the author with the project “Active Control for Performance Limit” (ACPL). A series of fundamental results are obtained and will be disseminated in this book. The results are verified through extensive numerical demonstrations and are expected to provide useful guidance for practical engineering in the vibration and noise industry and research.

Actively Caring for Safety: The Psychological Science of Injury Prevention

by E. Scott Geller

Actively Caring for Safety: The Psychological Science of Injury Prevention outlines proactive applications of applied behavioural science and humanism (i.e., humanistic behaviourism) for improving health and safety. This text provides evidence-based principles for customizing effective processes for improving the human dynamics of safety and health in various locations—from home to the workplace, and throughout a community. World-renowned health/safety researcher, teacher, and consultant E. Scott Geller combines theory and principles in practical step-by-step procedures with behavioral science methods capable of enhancing safety awareness, reducing at-risk behavior, and facilitating ongoing participation in safety-related activities. Drawing upon his bestselling works Working Safe and The Psychology of Safety Handbook, this book presents a science-based and practical approach to improving attitudes and behavior for achieving an injury-free work environment. The text has been improved and updated throughout and includes additional material on a rationale for language to replace common safety-related words that stifle human engagement. Plus, critical safety-relevant information is provided on empathy, emotional intelligence, self-motivation, positive psychology, psychological safety, the dramatic benefits of promoting perceptions of personal choice, and critical distinctions between leadership and management for optimizing workplace safety and productivity.Written in an enjoyable, anecdotal, and engaging style, this is an essential read for any student, academic, researcher, or professional of health and safety.

Activist Science and Technology Education (Cultural Studies of Science Education #9)

by Larry Bencze Steve Alsop

This collection examines issues of agency, power, politics and identity as they relate to science and technology and education, within contemporary settings. Social, economic and ecological critique and reform are examined by numerous contributing authors, from a range of international contexts. These chapters examine pressing pedagogical questions within socio-scientific contexts, including petroleum economies, food justice, health, environmentalism, climate change, social media and biotechnologies. Readers will discover far reaching inquiries into activism as an open question for science and technology education, citizenship and democracy. The authors call on the work of prominent scholars throughout the ages, including Bourdieu, Foucault, Giroux, Jasanoff, Kierkegaard, Marx, Nietzsche, Rancière and Žižek. The application of critical theoretical scholarship to mainstream practices in science and technology education distinguishes this book, and this deep, theoretical treatment is complemented by many grounded, more pragmatic exemplars of activist pedagogies. Practical examples are set within the public sphere, within selected new social movements, and also within more formal institutional settings, including elementary and secondary schools, and higher education. These assembled discussions provide a basis for a more radically reflexive reworking of science and technology education. Educational policy makers, science education scholars, and science and technology educators, amongst others, will find this work thought-provoking, instructive and informative.

Activity Systems Analysis Methods: Understanding Complex Learning Environments

by Lisa C. Yamagata-Lynch

In the last two decades, there has been growing interest in pursuing theoretical paradigms that capture complex learning situations. Cultural Historical Activity Theory (CHAT) is one of several theoretical frameworks that became very popular among educational researchers because it conceptualizes individuals and their environment as a holistic unit of analysis. It assumes a non-dualistic ontology and acknowledges the complexities involved in human activity in natural settings. Recently, reputable journals such as the American Psychologist, Educational Psychologist, and Educational Researcher that are targeted for a wide-range of audience have included articles on CHAT. In many of such articles, CHAT has been referred to as social constructivism, sociocultural theory, or activity theory. Activity systems analysis is one of the popular methods among CHAT researchers for mapping complex human interactions from qualitative data. However, understanding the methods involved in activity systems analysis is a challenging task for many researchers. This difficulty derives from several reasons. First the original texts of CHAT are in Russian and there have been numerous authors who report on the difficulties of reconciling translation problems of the works of original authors' such as Vygotsky and Leontiev. Second, in North America activity systems analysis has deviated from the Russian scholars' intentions and Engeström's original work using the triangle model to identify tensions to overcome and bring about sociopolitical change in participant practices. Third, to this date there are numerous publications on the theoretical background of activity theory and studies reporting the results of using activity systems analysis for unpacking qualitative data sets, but there have been no methodological publications on how researchers engage in activity systems analysis. Thus, there is a dearth of literature in both book and journal publications that guide researchers on the methodological issues involving activity systems analysis.

Activity Theory, Authentic Learning and Emerging Technologies: Towards a transformative higher education pedagogy (Routledge Research in Higher Education)

by Denise Wood Vivienne Bozalek Dick Ng’ambi Jan Herrington Joanne Hardman Alan Amory

Although emerging technologies are becoming popularised for teaching, learning and research, the relationship between their use and transformative effects on higher education remain largely unexplored. This edited collection seeks to fill this gap by providing a nuanced view, locating higher education pedagogical practices at an intersection of emerging technologies, authentic learning and activity systems. Providing numerous case studies as examples, the book draws from a wide range of contexts to illustrate how such a convergence has the potential to track transformative teaching and learning practices in the higher education sector. Chapters provide the reader with a variety of transformative higher education pedagogical practices in southern contexts, theorised within the framework of Cultural Historical Activity Theory (CHAT) and tool mediation, while using authentic learning as a pedagogical model upon which this theoretical framework is based. The topics covered in the book have global relevance, with research paying particular attention to South Africa, Australia and New Zealand, where the authors are based. The book will be of interest to educators, researchers and practitioners in higher education, as well as those interested in emerging technologies in education more generally.

Acute Exposure Guideline Levels for Selected Airborne Chemicals

by Committee on Acute Exposure Guideline Levels

The Bhopal Disaster of 1984 resulted in the death of around 2,000 residents living near chemical plants and irreversible injuries to more than 20,000 other residents. These numbers can be attributed to the community's lack of awareness concerning the chemicals' existence, dangers and effects, and/or how to react in case of emergency. The disaster emphasized the need for governments to identify hazardous substances and to aid local communities in developing plans for emergency exposures. As a result, the United States government issued the Superfund Amendments and Reauthorization Act (SARA) of 1986; requiring the identification of extremely hazardous substances (EHSs) by the Environmental Protection Agency (EPA). EPA was also tasked with assisting Local Emergency Planning Committees (LEPCs) in conducting health-hazard assessments to develop emergency-response plans for sites where EHSs are produced, stored, transported, or used. The EPA identified nearly 400 EHSs in terms of their immediate danger to life and health (IDLH) as their first step in assisting these LEPCs. In 1991 the EPA went on to request that the National Research Council (NRC) Committee on Toxicology (COT) develop criteria and methods for developing emergency exposure levels for EHSs for the general population. The COT, who had published many reports on emergency exposure guidance levels at the time, designated the task to a subcommittee. The subcommittee focused on Guidelines for Developing Community Emergency Exposure Levels for Hazardous Substances. Four years later the National Advisory Committee for Acute Exposure Guideline Levels for Hazardous Substances (NAC) was created with a focus on identifying, reviewing, and interpreting relevant toxicologic and other scientific data and developing acute exposure guideline levels (AEGLs) for high-priority, acutely toxic chemicals. In Acute Exposure Guideline Levels for Selected Airborne Chemicals: Volume 4, the NAC outlines acute exposure guideline levels for chlorine, hydrogen chloride, toluene 2,4, hydrogen fluoride, 2,6-diisocyanate, and uranium hexafluoride.

Ad Hoc Networks Telecommunications and Game Theory

by Malek Benslama Hadj Batatia Mohamed Lamine Boucenna

Random SALOHA and CSMA protocols that are used to access MAC in ad hoc networks are very small compared to the multiple and spontaneous use of the transmission channel. So they have low immunity to the problems of packet collisions. Indeed, the transmission time is the critical factor in the operation of such networks.The simulations demonstrate the positive impact of erasure codes on the throughput of the transmission in ad hoc networks. However, the network still suffers from the intermittency and volatility of its efficiency throughout its operation, and it switches quickly to the saturation zone. In this context, game theory has demonstrated his ability to lead the network to a more efficient equilibrium. This, we were led to propose our model code set that formalizes the behavior of nodes during transmission within SALOHA networks and CSMA respectively
