Active Learning to Minimize the Possible Risk of Future Epidemics (SpringerBriefs in Applied Sciences and Technology)
by KC Santosh Suprim NakarmiFuture epidemics are inevitable, and it takes months and even years to collect fully annotated data. The sheer magnitude of data required for machine learning algorithms, spanning both shallow and deep structures, raises a fundamental question: how big data is big enough to effectively tackle future epidemics? In this context, active learning, often referred to as human or expert-in-the-loop learning, becomes imperative, enabling machines to commence learning from day one with minimal labeled data. In unsupervised learning, the focus shifts toward constructing advanced machine learning models like deep structured networks that autonomously learn over time, with human or expert intervention only when errors occur and for limited data—a process we term mentoring. In the context of Covid-19, this book explores the use of deep features to classify data into two clusters (0/1: Covid-19/non-Covid-19) across three distinct datasets: cough sound, Computed Tomography (CT) scan, and chest x-ray (CXR). Not to be confused, our primary objective is to provide a strong assertion on how active learning could potentially be used to predict disease from any upcoming epidemics.

Active Lighting and Its Application for Computer Vision: 40 Years of History of Active Lighting Techniques (Advances in Computer Vision and Pattern Recognition)
by Katsushi Ikeuchi Yasuyuki Matsushita Ryusuke Sagawa Hiroshi Kawasaki Yasuhiro Mukaigawa Ryo Furukawa Daisuke MiyazakiThis book describes active illumination techniques in computer vision. We can classify computer vision techniques into two classes: passive and active techniques. Passive techniques observe the scene statically and analyse it as is. Active techniques give the scene some actions and try to facilitate the analysis. In particular, active illumination techniques project specific light, for which the characteristics are known beforehand, to a target scene to enable stable and accurate analysis of the scene. Traditional passive techniques have a fundamental limitation. The external world surrounding us is three-dimensional; the image projected on a retina or an imaging device is two-dimensional. That is, reduction of one dimension has occurred. Active illumination techniques compensate for the dimensional reduction by actively controlling the illumination. The demand for reliable vision sensors is rapidly increasing in many application areas, such as robotics and medical image analysis. This book explains this new endeavour to explore the augmentation of reduced dimensions in computer vision. This book consists of three parts: basic concepts, techniques, and applications. The first part explains the basic concepts for understanding active illumination techniques. In particular, the basic concepts of optics are explained so that researchers and engineers outside the field can understand the later chapters. The second part explains currently available active illumination techniques, covering many techniques developed by the authors. The final part shows how such active illumination techniques can be applied to various domains, describing the issue to be overcome by active illumination techniques and the advantages of using these techniques. This book is primarily aimed at 4th year undergraduate and 1st year graduate students, and will also help engineers from fields beyond computer vision to use active illumination techniques. Additionally, the book is suitable as course material for technical seminars.

Active Packaging for Various Food Applications
by M. SelvamuthukumaranMicrobial attacks occur on food surfaces even when the food is packaged. This can be attributed to moisture permeability in the packaging materials and other environmental conditions. Therefore, active agents like antimicrobial components and antioxidants must be incorporated into the packaging system; these active agents function by enhancing the stability of the product to a greater extent. Implementing an active packaging system ensures the safety and quality aspects of packaged foods so that consumers may use the products without worry. Active Packaging for Various Food Applications addresses the significance of active packaging for enhancing the quality and safety of various packaged foods. This book discusses extending the shelf life of various food products by incorporating various active packaging systems. It also addresses bioactive materials used for packing food products and applications of nanomaterials in an active packaging system. Key Features: Describes the uses of active packaging materials for various food processing industries like dairy, cereals, fruits and vegetables, meat, etc. Explains the application of biosensors for the detection of spoilage of active packed food products Discusses the importance of active packaging techniques for retaining antioxidants and micro as well as macronutrients Highlights the importance of active packaging of foods and its advantages This book is a great source for academicians, scientists, research scholars, and food industry personnel because it sheds light on the recent techniques used in active packaging systems for enhancing quality aspects.
Active Plasmonic Devices: Based on Magnetoplasmonic Nanostructures (Springer Theses)
by Diana Martín BecerraThis thesis investigates the effect of the magnetic field on propagating surface plasmon polaritons (SPPs), or surface plasmons for short. Above all, it focuses on using the magnetic field as an external agent to modify the properties of the SPPs, and therefore achieving active devices. Surface plasmons are evanescent waves that arise at metal-dielectric interfaces. They can be strongly confined (beyond the light diffraction limit), and provide a strong enhancement of the electromagnetic field at the interface. These waves have led to the development of plasmonic circuitry, which is a key candidate as an alternative to electronic circuitry and traditional optical telecommunication devices, since it is faster than the former and less bulky than the latter. Adopting both a theoretical and an experimental point of view, the book analyzes the magnetic modulation in SPPs by means of an interferometer engraved in a multilayer combining Au and Co. In this interferometer, which acts like a modulator, the SPP magnetic modulation is studied in detail, as are the parameters that have a relevant impact on it, simple ways to enhance it, its spectral dependence, and the highly promising possibility of using this system for biosensing. The thesis ultimately arrives at the conclusion that this method can provide values of modulations similar to other active methods used in plasmonics.

Active Protective Coatings: New-Generation Coatings for Metals (Springer Series in Materials Science #233)
by Anthony E. Hughes Johannes M.C. Mol Mikhail L. Zheludkevich Rudolph G. BuchheitThis book coversa broad range of materials science that has been brought to bear on providingsolutions to the challenges of developing self-healing and protective coatingsfor a range of metals. The book has a strong emphasis on characterisationtechniques, particularly new techniques that are beginning to be used in thecoatings area. It features many contributions written by experts from variousindustrial sectors which examine the needs of the sectors and the state of theart. The developmentof self-healing and protective coatings has been an expanding field in recentyears and applies a lot of new knowledge gained from other fields as well asother areas of materials science to the development of coatings. It hasborrowed from fields such as the food and pharmaceutical industries who haveused, polymer techniques, sol-gel science and colloidosome technology for arange encapsulation techniques. It has also borrowed from fields like hydrogenstorage such as from the development of hierarchical and other materials basedon organic templating as "nanocontainers" for the delivery of inhibitors. Inmaterials science, recent developments in high throughput and othercharacterisation techniques, such as those available from synchrotrons, arebeing increasing used for novel characterisation - one only needs to look atthe application of these techniques in self healing polymers to gauge wealth ofnew information that has been gained from these techniques. This work islargely driven by the need to replace environmental pollutants and hazardouschemicals that represent risk to humans such as chromate inhibitors which arestill used in some applications.
Active Rheology Control of Cementitious Materials (Modern Concrete Technology #23)
by Geert De Schutter Karel LesageThis book reports on cutting-edge research within the new field of active rheology control of cementitious materials, presenting new ideas developed within the ERC Advanced Grant Project, SmartCast (hosted at Ghent University), which extend the possibilities of admixtures and additions beyond current options. The research presented here develops a new method of actively controlling the rheology of fresh concrete during casting operations by incorporating specially designed responsive components. This results in real-time changes to the rheological behaviour of the cementitious material, allowing the user to intervene actively after the cementitious material has left the mixing phase. This newly gained agility contributes to increased processing speed and placement reliability in the case of traditional casting methods and can also facilitate advanced 3D concrete printing. The different routes followed to achieve this Active Rheology Control are explained within. The book suits researchers and innovative practitioners and is the first comprehensive text to present these new findings.

Active Robust Optimization: Optimizing for Robustness of Changeable Products (Springer Theses)
by Shaul SalomonThis book presents a novel framework, known as Active Robust Optimization, which provides the tools for evaluating, comparing and optimizing changeable products. Since any product that can change its configuration during normal operation may be considered a “changeable product,” the framework is widely applicable. Further, the methodology enables designers to use adaptability to deal with uncertainties and so avoid over-conservative designs. Offering a comprehensive overview of the framework, including its unique features, such as its ability to optimally respond to uncertain situations, the book also defines a new class of optimization problem and examines the effects of changes in various parameters on their solution. Lastly, it discusses innovative approaches for solving the problem and demonstrates these with two examples from different fields in engineering design: optimization of an optical table and optimization of a gearbox.

Active Structural Control with Stable Fuzzy PID Techniques (SpringerBriefs in Applied Sciences and Technology)
by Wen Yu Suresh ThenozhiThis 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 System Control: Design of System Resilience
by Igor Schagaev Brian KirkNow in its second edition, this book introduces an approach to active system control. This approach, when applied through design and development improves our technological systems. It extends concepts of system control using data accumulation, state and structural dependencies. The authors define these properties in terms of reliability, performance and energy-efficiency, and self-adaption. They describe how they bridge the gap between data accumulation and analysis in terms of interpolation with the real physical models when data used for interpretation of the system conditions. The authors introduce a principle of active system control and safety - an approach that explains what a model of a system should have, making computer systems more efficient, a crucial new concern in application domains such as safety critical, embedded and low-power autonomous systems like transport, healthcare, and other dynamic systems with moving substances and elements. On a theoretical level, this book further extends the concept of fault tolerance, introducing a system level of design for improving overall efficiency. On a practical level it illustrates how active system approach might help our systems become self-evolving. This updated new edition of Active System Control contains new chapters on the system software concept and the future of active systems control and a chapter containing case studies of unsolved aviation safety incidents.

Active Vibration & Noise Control: A New Paradigm to Active Control
by Jiqiang WangThe 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 GellerActively 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 AlsopThis 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.
