System Dynamics Modeling with R
by Jim DugganThis new interdisciplinary work presents system dynamics as a powerful approach to enable analysts build simulation models of social systems, with a view toward enhancing decision making. Grounded in the feedback perspective of complex systems, the book provides a practical introduction to system dynamics, and covers key concepts such as stocks, flows, and feedback. Societal challenges such as predicting the impact of an emerging infectious disease, estimating population growth, and assessing the capacity of health services to cope with demographic change can all benefit from the application of computer simulation. This text explains important building blocks of the system dynamics approach, including material delays, stock management heuristics, and how to model effects between different systemic elements. Models from epidemiology, health systems, and economics are presented to illuminate important ideas, and the R programming language is used to provide an open-source and interoperable way to build system dynamics models. System Dynamics Modeling with R also describes hands-on techniques that can enhance client confidence in system dynamic models, including model testing, model analysis, and calibration. Developed from the author's course in system dynamics, this book is written for undergraduate and postgraduate students of management, operations research, computer science, and applied mathematics. Its focus is on the fundamental building blocks of system dynamics models, and its choice of R as a modeling language make it an ideal reference text for those wishing to integrate system dynamics modeling with related data analytic methods and techniques.
System Dynamics with Interaction Discontinuity
by Albert C. J. Luo Dennis M. O'ConnorThis book describes system dynamics with discontinuity caused by system interactions and presents the theory of flow singularity and switchability at the boundary in discontinuous dynamical systems. Based on such a theory, the authors address dynamics and motion mechanism of engineering discontinuous systems due to interaction. Stability and bifurcations of fixed points in nonlinear discrete dynamical systems are presented, and mapping dynamics are developed for analytical predictions of periodic motions in engineering discontinuous dynamical systems. Ultimately, the book provides an alternative way to discuss the periodic and chaotic behaviors in discontinuous dynamical systems.
System Earth via Geodetic-Geophysical Space Techniques
by Frank M. Flechtner Jens Wickert Markus Rothacher Thomas Gruber M. Mandea Andreas Güntner Tilo SchöneThe Earth's magnetic and gravity field play an important role in global and regional geodynamics. Satellite exploration of these fields has received great attention in recent years. Research satellites such as CHAMP and GRACE as well as the ESA explorer GOCE apply new measurement techniques, thus allowing the recovery of the gravitational and magnetic field with unprecedented accuracy and resolution, spatial as well as temporal. Combined with terrestrial observations and computer models, this data will help develop a more detailed understanding of the Earth as a system. In Germany, many of the processing, modelling and interpreting methodologies for these new observation techniques are developed under the umbrella of the R&D-programme GEOTECHNOLOGIEN, funded by the Federal Ministry of Education and Research (BMBF). The research projects focus on a better understanding of the spatial and temporal variations in the magnetic and gravity field and their relationship to the dynamics of the Earth's interior and global change processes. This volume presents the results of the multidisciplinary studies covered by the programme for the period 2005-2008. It includes the following topics: High-accuracy gravity field models, near-real-time provision and usage of CHAMP and GRACE atmospheric sounding, sea level variations, improved GRACE gravity time series and their validation by ocean bottom pressure measurements, integration of space geodetic techniques as a basis for the Global Geodetic-Geophysical Observing System (GGOS), high-resolution magnetic field models and global magnetisation maps and time-variable gravity and surface mass processes.

System Error: Where Big Tech Went Wrong and How We Can Reboot
by Rob Reich Mehran Sahami Jeremy M. Weinstein"System Error is a triumph: an analysis of the critical challenges facing our digital society that is as accessible as it is sophisticated." — Anne-Marie Slaughter, CEO of New AmericaA forward-thinking manifesto from three Stanford professors—experts who have worked at ground zero of the tech revolution for decades—which reveals how big tech’s obsession with optimization and efficiency has sacrificed fundamental human values and outlines steps we can take to change course, renew our democracy, and save ourselves.In no more than the blink of an eye, a naïve optimism about technology’s liberating potential has given way to a dystopian obsession with biased algorithms, surveillance capitalism, and job-displacing robots. Yet too few of us see any alternative to accepting the onward march of technology. We have simply accepted a technological future designed for us by technologists, the venture capitalists who fund them, and the politicians who give them free rein.It doesn’t need to be this way.System Error exposes the root of our current predicament: how big tech’s relentless focus on optimization is driving a future that reinforces discrimination, erodes privacy, displaces workers, and pollutes the information we get. This optimization mindset substitutes what companies care about for the values that we as a democratic society might choose to prioritize. Well-intentioned optimizers fail to measure all that is meaningful and, when their creative disruptions achieve great scale, they impose their values upon the rest of us.Armed with an understanding of how technologists think and exercise their power, three Stanford professors—a philosopher working at the intersection of tech and ethics, a political scientist who served under Obama, and the director of the undergraduate Computer Science program at Stanford (also an early Google engineer)—reveal how we can hold that power to account.Troubled by the values that permeate the university’s student body and its culture, they worked together to chart a new path forward, creating a popular course to transform how tomorrow’s technologists approach their profession. Now, as the dominance of big tech becomes an explosive societal conundrum, they share their provocative insights and concrete solutions to help everyone understand what is happening, what is at stake, and what we can do to control technology instead of letting it control us.
System Identification
by Karel J. KeesmanSystem Identification shows the student reader how to approach the system identification problem in a systematic fashion. The process is divided into three basic steps: experimental design and data collection; model structure selection and parameter estimation; and model validation, each of which is the subject of one or more parts of the text. Following an introduction on system theory, particularly in relation to model representation and model properties, the book contains four parts covering: * data-based identification - non-parametric methods for use when prior system knowledge is very limited; * time-invariant identification for systems with constant parameters; * time-varying systems identification, primarily with recursive estimation techniques; and * model validation methods. A fifth part, composed of appendices, covers the various aspects of the underlying mathematics needed to begin using the text. The book uses essentially semi-physical or gray-box modeling methods although data-based, transfer-function system descriptions are also introduced. The approach is problem-based rather than rigorously mathematical. The use of finite input-output data is demonstrated for frequency- and time-domain identification in static, dynamic, linear, nonlinear, time-invariant and time-varying systems. Simple examples are used to show readers how to perform and emulate the identification steps involved in various control design methods with more complex illustrations derived from real physical, chemical and biological applications being used to demonstrate the practical applicability of the methods described. End-of-chapter exercises (for which a downloadable instructors' Solutions Manual is available from fill in URL here) will both help students to assimilate what they have learned and make the book suitable for self-tuition by practitioners looking to brush up on modern techniques. Graduate and final-year undergraduate students will find this text to be a practical and realistic course in system identification that can be used for assessing the processes of a variety of engineering disciplines. System Identification will help academic instructors teaching control-related to give their students a good understanding of identification methods that can be used in the real world without the encumbrance of undue mathematical detail.
System Identification and Adaptive Control
by Yiannis Boutalis Dimitrios Theodoridis Theodore Kottas Manolis A. ChristodoulouPresenting current trends in the development and applications of intelligent systems in engineering, this monograph focuses on recent research results in system identification and control. The recurrent neurofuzzy and the fuzzy cognitive network (FCN) models are presented Both models are suitable for partially-known or unknown complex time-varying systems. Neurofuzzy Adaptive Control contains rigorous proofs of its statements which result in concrete conclusions for the selection of the design parameters of the algorithms presented. The neurofuzzy model combines concepts from fuzzy systems and recurrent high-order neural networks to produce powerful system approximations that are used for adaptive control. The FCN model stems from fuzzy cognitive maps and uses the notion of "concepts" and their causal relationships to capture the behavior of complex systems. The book shows how, with the benefit of proper training algorithms, these models are potent system emulators suitable for use in engineering systems All chapters are supported by illustrative simulation experiments, while separate chapters are devoted to the potential industrial applications of each model including projects in: * contemporary power generation; * process control and * conventional benchmarking problems. Researchers and graduate students working in adaptive estimation and intelligent control will find Neurofuzzy Adaptive Control of interest both for the currency of its models and because it demonstrates their relevance for real systems. The monograph also shows industrial engineers how to test intelligent adaptive control easily using proven theoretical results.

System Identification Using Regular and Quantized Observations
by Le Yi Wang George G. Yin Qi HeThis brief presents characterizations of identification errors under a probabilistic framework when output sensors are binary, quantized, or regular. By considering both space complexity in terms of signal quantization and time complexity with respect to data window sizes, this study provides a new perspective to understand the fundamental relationship between probabilistic errors and resources, which may represent data sizes in computer usage, computational complexity in algorithms, sample sizes in statistical analysis and channel bandwidths in communications.
System Innovation for Sustainability 1: Perspectives on Radical Changes to Sustainable Consumption and Production
by Arnold Tukker Martin Charter Carlo Vezzoli Eivind Stø Maj Munch AndersenSustainable consumption and production (SCP) was adopted as a priority area during the World Summit on Sustainable Development in Johannesburg in 2002 and has since become one of the main vehicles for targeting international sustainability policy. Sustainable consumption focuses on formulating equitable strategies that foster the highest quality of life, the efficient use of natural resources, and the effective satisfaction of human needs while simultaneously promoting equitable social development, economic competitiveness, and technological innovation. But this is a complex topic and, as the challenges of sustainability grow larger, there is a need to re-imagine how SCP policies can be formulated, governed and implemented. The EU-funded project "Sustainable Consumption Research Exchanges" (SCORE!) consists of around 200 experts in the field of sustainable innovation and sustainable consumption. The SCORE! philosophy is that innovation in SCP policy can be achieved only if experts that understand business development, (sustainable) solution design, consumer behaviour and system innovation policy work together in shaping it. Sustainable technology design can be effective only if business can profitably make the products and consumers are attracted to them. To understand how this might effectively happen, the expertise of systems thinkers must be added to the mix. System Innovation for Sustainability 1 is the first result of a unique positive confrontation between experts from all four communities. It examines what SCP is and what it could be, provides a state-of-the-art review on the governance of change in SCP policy and looks at the strengths and weaknesses of current approaches. The SCORE! experts are working with actors in industry, consumer groups and eco-labelling organisations in the key consumption areas of mobility, food and agriculture, and energy use and housing – responsible for 70% of the life-cycle environmental impacts of Western societies – with the aim of stimulating, fostering or forcing change to SCP theory in practice. The System Innovation for Sustainability series will continue with three further volumes of comprehensive case studies in each of these three critical consumption areas. Each chapter of this book examines problems and suggests solutions from a business, design, consumer and system innovation perspective. It primarily examines the differing solutions necessary in the consumer economies of the West, but also comments on the differing needs in rapidly emerging economies such as China, as well as base-of-the-pyramid economies. The System Innovation for Sustainability series is the fruit of the only major international research network on SCP and will set the standard in this field for some years to come. It will be required reading for all involved in the policy debate on sustainable production and consumption from government, business, academia and NGOs for designers, scientists, businesses and system innovators.
System Level ESD Protection
by Vladislav Vashchenko Mirko ScholzThis book addresses key aspects of analog integrated circuits and systems design related to system level electrostatic discharge (ESD) protection. It is an invaluable reference for anyone developing systems-on-chip (SoC) and systems-on-package (SoP), integrated with system-level ESD protection. The book focuses on both the design of semiconductor integrated circuit (IC) components with embedded, on-chip system level protection and IC-system co-design. The readers will be enabled to bring the system level ESD protection solutions to the level of integrated circuits, thereby reducing or completely eliminating the need for additional, discrete components on the printed circuit board (PCB) and meeting system-level ESD requirements. The authors take a systematic approach, based on IC-system ESD protection co-design. A detailed description of the available IC-level ESD testing methods is provided, together with a discussion of the correlation between IC-level and system-level ESD testing methods. The IC-level ESD protection design is demonstrated with representative case studies which are analyzed with various numerical simulations and ESD testing. The overall methodology for IC-system ESD co-design is presented as a step-by-step procedure that involves both ESD testing and numerical simulations.

System Modeling in Cell Biology: From Concepts to Nuts and Bolts
by Zoltan Szallasi Vipul Periwal Jorg StellingResearch in systems biology requires the collaboration of researchers from diverse backgrounds, including biology, computer science, mathematics, statistics, physics, and biochemistry. These collaborations, necessary because of the enormous breadth of background needed for research in this field, can be hindered by differing understandings of the limitations and applicability of techniques and concerns from different disciplines. This comprehensive introduction and overview of system modeling in biology makes the relevant background material from all pertinent fields accessible to researchers with different backgrounds. The emerging area of systems level modeling in cellular biology has lacked a critical and thorough overview. This book fills that gap. It is the first to provide the necessary critical comparison of concepts and approaches, with an emphasis on their possible applications. It presents key concepts and their theoretical background, including the concepts of robustness and modularity and their exploitation to study biological systems; the best-known modeling approaches, and their advantages and disadvantages; lessons from the application of mathematical models to the study of cellular biology; and available modeling tools and datasets, along with their computational limitations.
System of Open Spaces
by Raquel TardinIn the current panorama of urban growth and planning in many urban territories of western societies, open spaces are residual spaces of urban occupation or are reserved for eventual occupation. Open spaces have been viewed in this manner in the earlier stages of the compact city and especially now, in a time of the dispersed territories characterized by discontinuity, heterogeneity, and fragmentation. The disciplinary perspectives of ecology, geology, landscape architecture, and urbanism, but also public opinion, have for some time promoted the conservation and protection of the most valuable natural spaces, and efforts have been made to remove such spaces from the real estate market. However, such positions, usually radical, are insufficient for territorial equilibrium and inevitably lead to the progressive disappearance of valuable natural spaces.

System under Stress: Homeland Security and American Politics
by Donald F. KettlFor the purposes of the study of American government, suggests Kettl (political science, U. of Pennsylvania), the 9-11 terrorist attacks and the Hurricane Katrina disaster were "stress tests" analogous to those run by a cardiologist to diagnose the health of a patient's heart. He offers his own diagnosis of the US government's homeland security health as revealed by these events, discussing intelligence failures prior to the 9-11 attacks and the government's response, broader coordination problems in the federal bureaucracy, state and local government responses to Hurricane Katrina, the policy problem of trying to maximize protection against threats that can't be eliminated, and the alleged conflict between security and civil rights and liberties.
