Adaptive Thermal Comfort of Indoor Environment for Residential Buildings: Efficient Strategy for Saving Energy (SpringerBriefs in Architectural Design and Technology)
by Carlos Rubio-Bellido David Bienvenido-HuertasThis book is structured in four parts: First, it analyzes the sustainability objectives established for the building stock and the importance of thermal comfort in this aspect. Second, the existing adaptive thermal comfort models and the main energy-saving measures associated with these models are analyzed. Third, the energy savings obtained with these measures are analyzed in several case studies, comparing the results obtained with other energy conservation measures, such as the improvement of the façade. The analysis is carried out from an energy and economic perspective. Finally, a decision‐making process based on fuzzy logic is established. As an expected result, the content of the book contributes to assist architects in designing more efficient buildings from the perspective of user behavior.
Adaptive Thermal Comfort: Foundations And Analysis
by Susan Roaf Michael Humphreys Fergus NicolThere has been widespread dissatisfaction with accepted models for predicting the conditions that people will find thermally comfortable in buildings. These models require knowledge about clothing and activity, but can give little guidance on how to quantify them in any future situation. This has forced designers to make assumptions about people’s future behaviour based on very little information and, as a result, encouraged static design indoor temperatures. This book is the second in a three volume set covering all aspects of Adaptive Thermal Comfort. The first part narrates the development of the adaptive approach to thermal comfort from its early beginnings in the 1960s. It discusses recent work in the field and suggests ways in which it can be developed and modelled. Such models can be used to set dynamic, interactive standards for thermal comfort which will help overcome the problems inherited from the past. The second part of the volume engages with the practical and theoretical problems encountered in field studies and in their statistical analysis, providing guidance towards their resolution, so that valid conclusions may be drawn from such studies.
Adaptive Thermal Comfort: The Designer's Guide To Adaptive Thermal Comfort
by Susan Roaf Michael Humphreys Fergus NicolThe fundamental function of buildings is to provide safe and healthy shelter. For the fortunate they also provide comfort and delight. In the twentieth century comfort became a 'product' produced by machines and run on cheap energy. In a world where fossil fuels are becoming ever scarcer and more expensive, and the climate more extreme, the challenge of designing comfortable buildings today requires a new approach. This timely book is the first in a trilogy from leaders in the field which will provide just that. It explains, in a clear and comprehensible manner, how we stay comfortable by using our bodies, minds, buildings and their systems to adapt to indoor and outdoor conditions which change with the weather and the climate. The book is in two sections. The first introduces the principles on which the theory of adaptive thermal comfort is based. The second explains how to use field studies to measure thermal comfort in practice and to analyze the data gathered. Architects have gradually passed responsibility for building performance to service engineers who are largely trained to see comfort as the ‘product’, designed using simplistic comfort models. The result has contributed to a shift to buildings that use ever more energy. A growing international consensus now calls for low-energy buildings. This means designers must first produce robust, passive structures that provide occupants with many opportunities to make changes to suit their environmental needs. Ventilation using free, natural energy should be preferred and mechanical conditioning only used when the climate demands it. This book outlines the theory of adaptive thermal comfort that is essential to understand and inform such building designs. This book should be required reading for all students, teachers and practitioners of architecture, building engineering and management – for all who have a role in producing, and occupying, twenty-first century adaptive, low-carbon, comfortable buildings.
Adaptive User Support: Ergonomic Design of Manually and Automatically Adaptable Software
by Reinhard OppermannThe potential of software applications to solve an array of office and administrative problems is increasing faster than the ability of users to exploit it. We need to make systems easier to learn and more comfortable to use. This book reports a major advance in the effort to accomplish both goals. Flexcel enables users to modify access and dialog dynamics to their specific requirements. Relying on a plan recognition feature, the system proposes adaptations or uses of adaptations. The ongoing conflict between the adaptive and the adaptable is resolved in an integration: user and system share the responsibility for the initiatives, decision-making and execution. A "critic" component of the system then analyzes the user's handling of the adaptation tools and suggests improvements. The system offers an environment in which users can explore as they learn. HyPlan implements the context-sensitive help that facilitates learning on demand. When the PLANET plan-recognition feature identifies the kinds of support for work that may possibly be required, HyPlan provides, on request, specific assistance in the form of hypermedia or animated displays and tutorials. Developmental research has shown that users take advantage of opportunities to adapt interfaces only in conjunction with help-functions -- which are accepted when they do not interrupt work. And studies by social scientists have shown that adaptations of technical systems have to be integrated into the overall process of organizational innovation and undertaken cooperatively. This book will stimulate all those concerned with software -- from computational, cognitive, ergonomic, or organizational standpoints -- to reconceive the relationship between design and user support.
Adaptive Water Management: Concepts, Principles and Applications for Sustainable Development (International Series in Operations Research & Management Science #258)
by Farideh Delavari Edalat M. Reza AbdiThis book explores a new framework of Adaptive Water Management (AWM) for evaluating existing approaches in urban water management. It highlights the need to adopt multidisciplinary strategies in water management while providing an in-depth understanding of institutional interactions amongst different water related sectors. The key characteristics of AWM i. e. polycentric governance, organisational flexibility and public participation are investigated and described through a critical review of the relevant literature. The book presents an empirical case study undertaken in a selected developing-country city to investigate the potential gaps between the current water management approaches and possible implementation of AWM. Feasibility of AWM operations is examined in an environment surrounded by established water management structure with centralised governance and an institutional process based on technical flexibility. The key elements of AWM performance are (re)structured and transformed into decision support systems. Multi criteria decision models are developed to facilitate quantification and visualization of the elements derived from the case study, which is involved with water companies and water consumers. The book describes how the concept of AWM, along with structuring suitable decision support systems, can be developed and applied to developing-country cities. The book highlights the barriers for applying the AWM strategies that include established centralised decision making, bureaucratic interactions with external organisations, lack of organisational flexibility within the institutions, and lack of recognition of public role in water management. The findings outline that despite the lack of adaptability in the current water management in the case study, as an example of developing countries, there are positive attitudes among water professionals and the public towards adaptability through public-institutional participation. /p>

Adaptive and Fault-Tolerant Control of Underactuated Nonlinear Systems (Automation and Control Engineering)
by Yong-Duan Song Jiangshuai HuangThe purpose of the book is to provide an exposition of recently developed adaptive and fault-tolerant control of underactuated nonlinear systems. Underactuated systems are abundant in real life, ranging from landing vehicles to surface ships and underwater vehicles to spacecrafts. For the tracking and stabilization control of underactuated mechanical systems, many methodologies have been proposed. However, a number of important issues deserve further investigation. In response to these issues, four important problems are solved in this book, including control of underactuated nonlinear systems with input saturation, output-feedback control in the presence of parametric uncertainties, fault-tolerant control of underactuated ships with or without actuator redundancy, and adaptive control of multiple underactauted nonlinear systems, including formation control and flocking control of multiple underactuated systems.
Adaptive and Learning-Based Control of Safety-Critical Systems (Synthesis Lectures on Computer Science)
by Calin Belta Max CohenThis book stems from the growing use of learning-based techniques, such as reinforcement learning and adaptive control, in the control of autonomous and safety-critical systems. Safety is critical to many applications, such as autonomous driving, air traffic control, and robotics. As these learning-enabled technologies become more prevalent in the control of autonomous systems, it becomes increasingly important to ensure that such systems are safe. To address these challenges, the authors provide a self-contained treatment of learning-based control techniques with rigorous guarantees of stability and safety. This book contains recent results on provably correct control techniques from specifications that go beyond safety and stability, such as temporal logic formulas. The authors bring together control theory, optimization, machine learning, and formal methods and present worked-out examples and extensive simulation examples to complement the mathematical style of presentation. Prerequisites are minimal, and the underlying ideas are accessible to readers with only a brief background in control-theoretic ideas, such as Lyapunov stability theory.
Adaptive and Robust Active Vibration Control: Methodology and Tests (Advances in Industrial Control)
by Ioan Doré Landau Tudor-Bogdan Airimițoaie Abraham Castellanos-Silva Aurelian ConstantinescuThis book approaches the design of active vibration control systems from the perspective of today s ideas of computer control. It formulates the various design problems encountered in the active management of vibration as control problems and searches for the most appropriate tools to solve them. The experimental validation of the solutions proposed on relevant tests benches is also addressed. To promote the widespread acceptance of these techniques, the presentation eliminates unnecessary theoretical developments (which can be found elsewhere) and focuses on algorithms and their use. The solutions proposed cannot be fully understood and creatively exploited without a clear understanding of the basic concepts and methods, so these are considered in depth. The focus is on enhancing motivations, algorithm presentation and experimental evaluation. MATLAB(r)routines, Simulink(r) diagrams and bench-test data are available for download and encourage easy assimilation of the experimental and exemplary material. Three major problems are addressed in the book: active damping to improve the performance of passive absorbers;adaptive feedback attenuation of single and multiple tonal vibrations; andfeedforward and feedback attenuation of broad band vibrations. Adaptive and Robust Active Vibration Control will interest practising engineers and help them to acquire new concepts and techniques with good practical validation. It can be used as the basis for a course for graduate students in mechanical, mechatronics, industrial electronics, aerospace and naval engineering. Readers working in active noise control will also discover techniques with a high degree of cross-over potential for use in their field. "

Adaptive-Robust Control with Limited Knowledge on Systems Dynamics: An Artificial Input Delay Approach and Beyond (Studies in Systems, Decision and Control #257)
by Spandan Roy Indra Narayan KarThe book investigates the role of artificial input delay in approximating unknown system dynamics, referred to as time-delayed control (TDC), and provides novel solutions to current design issues in TDC. Its central focus is on designing adaptive-switching gain-based robust control (ARC) for a class of Euler–Lagrange (EL) systems with minimal or no knowledge of the system dynamics parameters. The newly proposed TDC-based ARC tackles the commonly observed over- and under-estimation issues in switching gain. The consideration of EL systems lends a practical perspective on the proposed methods, and each chapter is supplemented by relevant experimental data. The book offers a unique resource for researchers in the areas of ARC and TDC alike, and covers the state of the art, new algorithms, and future directions.

Additive Fertigung für Chemiewissenschaften und Chemieingenieurwesen
by Seeram Ramakrishna Suresh K. Bhargava Milan Brandt Pr. SelvakannanDieses Buch ist speziell für Forscher sowie Lehrende konzipiert, die einen Fortgeschrittenen-Fertigungs-Kurs in ihren Klassen unterrichten oder einführen. Es präsentiert den aktuellen Forschungsstand in diesem Forschungsbereich und die bisher identifizierten Hauptprobleme für die Integration der additiven Fertigung in chemische Prozesse. Die einzigartige Fähigkeit, Materialien mithilfe aufkommender additiver Fertigungstechnologien in funktionale Bauteile mit spezifischer Geometrie zu verwandeln, hat in Biologie, Ingenieurwissenschaften und Materialwissenschaften erhebliches Interesse geweckt, um maßgeschneiderte Designs für spezifische Anwendungen zu erstellen. Die Anwendungen dieses aufstrebenden Fertigungsverfahren im Bereich der chemischen Wissenschaften und des Ingenieurwesens sind im Anfangssdtadium. Daher liegt der Hauptfokus dieses Buches darauf, die grundlegenden Prinzipien der additiven Fertigungsverfahren sowie den Einsatz in konventionelle chemische Prozesse und verschiedeneVerfahrenstechniken einzuführen. Der potenzielle Vorteil der Anwendung dieser additiven Fertigungstechnologien besteht darin, großtechnisch chemische Prozesse herunterzuskalieren, was mehrere Vorteile bietet, darunter eine geringere Flächenbedarf, Abfallreduktion, effiziente Wärmeintegration und dezentrale chemische Fertigung. Was ist Additive Fertigung? Additive Fertigung (engl.: additive manufacturing, AM) – weitgehend auch als 3D-Druck bezeichnet – ist ein aufstrebendes und innovatives Fertigungsverfahren, das sich grundlegend von konventionellen Herstellungsprozessen unterscheidet und der Forschung und Industrie zu völlig neuen Möglichkeiten verhilft. Bauteile werden Schicht für Schicht aufgebaut und entstehen nicht wie bei herkömmlichen Verfahren durch Abtrag von Material (zum Beispiel durch fräsende Bearbeitung). Dadurch ergibt sich eine enorme Flexibilität und Designfreiheit beispielsweise bei der Herstellung von Prototypen und auch zunehmend in der Serienfertigung. Die Zukunft der additiven Fertigung Die additive Fertigung zählt zu den starken Wachstumsfeldern innerhalb der Produktion. Führende Marktberichte sagen ein durchschnittliches jährliches Wachstum von ca. 20 Prozent für die nächsten fünf Jahre voraus. Das Fraunhofer IGCV geht dabei davon aus, dass dieses Branchenwachstum der additiven Fertigung nicht nur in einem spezifischen Industriezweig zu beobachten sein wird. Vielmehr ist davon auszugehen, dass in allen Industriezweigen der Einsatz additiver Fertigungsverfahren zunehmen wird. Im Jahr 2022 wurden zur Zukunft der additiven Fertigung zwei Studien (An Additive Manufacturing Breakthrough & The Futures of Metal Additive Manufacturing 2030) veröffentlicht, bei denen das Fraunhofer IGCV Zuarbeiten geleistet hat.
