Active Fault-Tolerant Control Systems: A Behavioral System Theoretic Perspective (Studies in Systems, Decision and Control #128)
by Tushar Jain Joseph J. Yamé Dominique SauterThe book introduces novel algorithms for designing fault-tolerant control (FTC) systems using the behavioral system theoretic approach, and presents a demonstration of successful novel FTC mechanisms on several benchmark examples. The authors also discuss a new transient management scheme, which is an essential requirement for the implementation of active FTC systems, and two data-driven methodologies that are broadly classified as active FTC systems: the projection-based approach and the online-redesign approach. These algorithms do not require much a priori information about the plant in real-time, and in addition this novel implementation of active FTC systems circumvents various weaknesses induced by using a diagnostic module in real-time. The book provides graduate students taking masters and doctoral courses in mathematics, control, and electrical engineering an excellent stepping-stone for their research. It also appeals to practitioners interested to apply innovative fail-safe control techniques.
Active Faults and Nuclear Regulation: Background to Requirement Enforcement in Japan
by Yasuhiro SuzukiThis book reviews the active faults around nuclear power plants in Japan and recommends an optimal method of nuclear power regulation controlled by the Nuclear Regulation Authority of Japan. The active faults around nuclear power plants have been underestimated in Japan since the latter half of the 20th century. However, based on the lessons learned from the Fukushima nuclear power plant accident, the book sheds light on why the risks of active faults were underestimated, and discusses the optimal scientific method of assessing those risks. Further, the author shares his experiences in the new standard for nuclear regulation creation team and in the active fault survey at the Nuclear Regulation Authority of Japan. This book is a valuable resource for students, researchers, academic and policy-makers, as well as non-experts interested in nuclear safety.
Active Filters: Theory and Design
by S.A. PactitisUsing an accessible yet rigorous approach, Active Filters: Theory and Design highlights the essential role of filters, especially analog active filters, in applications for seismology, brainwave research, speech and hearing studies, and other medical electronics. The book demonstrates how to design filters capable of meeting a given set of specifications. Recognizing that circuit simulation by computer has become an indispensable verification tool both in analysis and in design, the author emphasizes the use of MicroCap for rapid test of the filter. He uses three basic filter types throughout the book: Butterworth, Chenyshev, and Bessel. These three types of filters are implemented with the Sallen-Key, infinite gain multiple feedback, state-variable, and biquad circuits that yield low-pass, high-pass, band-pass, and band-reject circuits. The book illustrates many examples of low-pass, high-pass, band-pass, and notch active filters in complete detail, including frequency normalizing and denormalizing techniques. Design equations in each chapter provide students with a thorough grounding in how to implement designs. This detailed theoretical treatment gives you the tools to teach your students how to master filter design and analysis.

Active House: Smart Nearly Zero Energy Buildings (SpringerBriefs in Applied Sciences and Technology)
by Lone Feifer Marco Imperadori Graziano Salvalai Arianna Brambilla Federica BrunoneThe book provides an overview of the Active House (AH) vision, intended as a building design method “beyond” the passive approach for buildings of the future that will be more and more connected, smart and innovative. It offers a novel philosophical design approach in which buildings, new or renovated, are in balance with natural, renewable energies and become “concentrators-distributors” of energies instead of being consumers of resources. The book is composed of five chapters, providing information on fundamental aspects of innovations toward resource-efficient buildings, as well as case studies presenting the concept in practice. It demonstrates that a completely new design approach is possible, and that a turning point has been reached. Lastly, it shows how the AH Alliance, along with designers, institutions, industries and academies, is bringing a breath of fresh air to the world of construction.
The Active Image
by Sabine Ammon Remei Capdevila-WerningThe "active image" refers to the operative nature of images, thus capturing the vast array of "actions" that images perform. This volume features essays that present a new approach to image theory. It explores the many ways images become active in architecture and engineering design processes and how, in the age of computer-based modeling, images play an indispensable role. The contributors examine different types of images, be they pictures, sketches, renderings, maps, plans, and photographs; be they analog or digital, planar or three-dimensional, ephemeral, realistic or imaginary. Their essays investigate how images serve as means of representing, as tools for thinking and reasoning, as ways of imagining the inexistent, as means of communicating and conveying information and how images may also perform functions and have an agency in their own. The essays discuss the role of images from the perspective of philosophy, theory and history of architecture, history of science, media theory, cognitive sciences, design studies, and visual studies, offering a multidisciplinary approach to imagery and showing the various methodologies and interpretations in current research. In addition, they offer valuable insight to better understand how images operate and function in the arts and sciences in general.
Active Implants and Scaffolds for Tissue Regeneration (Studies in Mechanobiology, Tissue Engineering and Biomaterials #8)
by Meital ZilbermanActive implants are actually drug or protein-eluting implants that induce healing effects, in addition to their regular task, such as support. This effect is achieved by controlled release of the active agent to the surrounding tissue. This book will give a broad overview of biomaterial platforms used as basic elements of drug-eluting implants. It will include mainly coatings for vascular stents with controlled release of antiproliferative agents, wound dressings with controlled release of antibacterial agents, drug-eluting vascular grafts, protein-eluting scaffolds for tissue regeneration, drug-eluting platforms for dental and other applications. Thus, both internal and external implants are described. The drug-eluting implants will be described in terms of matrix formats and polymers, incorporated drugs and their release profiles from the implants, as well as implant functioning. Smart polymeric systems, such as crosslinked poly-lactones, thermo and pH-sensitive hydrogels and poly(amido-amines), as well as novel basic structural elements, such as composite fibers and films, and nanostructures will be thoroughly described. The effect of the processing parameters on the microstructure and on the resulting drug release profiles, mechanical and physical properties, and other relevant properties, will be emphasized. The described new biomaterials approaches for active implants enhance the tools available for creating clinically important biomedical applications.

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. The Open Access version of this book, available at http://www.taylorfrancis.com, has been made available under a Creative Commons Attribution-Non Commercial-No Derivatives 4.0 license.
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.
