Discrete-Event Modeling and Simulation: A Practitioner's Approach (Computational Analysis, Synthesis, and Design of Dynamic Systems)
by Gabriel A. WainerComplex artificial dynamic systems require advanced modeling techniques that can accommodate their asynchronous, concurrent, and highly non-linear nature. Discrete Event systems Specification (DEVS) provides a formal framework for hierarchical construction of discrete-event models in a modular manner, allowing for model re-use and reduced development time. Discrete Event Modeling and Simulation presents a practical approach focused on the creation of discrete-event applications. The book introduces the CD++ tool, an open-source framework that enables the simulation of discrete-event models. After setting up the basic theory of DEVS and Cell-DEVS, the author focuses on how to use the CD++ tool to define a variety of models in biology, physics, chemistry, and artificial systems. They also demonstrate how to map different modeling techniques, such as Finite State Machines and VHDL, to DEVS. The in-depth coverage elaborates on the creation of simulation software for DEVS models and the 3D visualization environments associated with these tools. A much-needed practical approach to creating discrete-event applications, this book offers world-class instruction on the field’s most useful modeling tools.
Discrete-Event Modeling and Simulation: Theory and Applications (Computational Analysis, Synthesis, and Design of Dynamic Systems)
by Pieter J. Mosterman Gabriel A. WainerCollecting the work of the foremost scientists in the field, Discrete-Event Modeling and Simulation: Theory and Applications presents the state of the art in modeling discrete-event systems using the discrete-event system specification (DEVS) approach. It introduces the latest advances, recent extensions of formal techniques, and real-world examples of various applications. The book covers many topics that pertain to several layers of the modeling and simulation architecture. It discusses DEVS model development support and the interaction of DEVS with other methodologies. It describes different forms of simulation supported by DEVS, the use of real-time DEVS simulation, the relationship between DEVS and graph transformation, the influence of DEVS variants on simulation performance, and interoperability and composability with emphasis on DEVS standardization. The text also examines extensions to DEVS, new formalisms, and abstractions of DEVS models as well as the theory and analysis behind real-world system identification and control. To support the generation and search of optimal models of a system, a framework is developed based on the system entity structure and its transformation to DEVS simulation models. In addition, the book explores numerous interesting examples that illustrate the use of DEVS to build successful applications, including optical network-on-chip, construction/building design, process control, workflow systems, and environmental models. A one-stop resource on advances in DEVS theory, applications, and methodology, this volume offers a sampling of the best research in the area, a broad picture of the DEVS landscape, and trend-setting applications enabled by the DEVS approach. It provides the basis for future research discoveries and encourages the development of new applications.
Discrete-Time and Discrete-Space Dynamical Systems (Communications and Control Engineering)
by Lihua Xie Lijun Zhang Kuize ZhangDiscrete-Time and Discrete-Space Dynamical Systems provides a systematic characterization of the similarities and differences of several types of discrete-time and discrete-space dynamical systems, including:Boolean control networks;nondeterministic finite-transition systems;finite automata;labelled Petri nets; andcellular automata.The book's perspective is primarily based on topological properties though it also employs semitensor-product and graph-theoretic methods where appropriate. It presents a series of fundamental results: invertibility, observability, detectability, reversiblity, etc., with applications to systems biology.Academic researchers with backgrounds in applied mathematics, engineering or computer science and practising engineers working with discrete-time and discrete-space systems will find this book a helpful source of new understanding for this increasingly important class of systems. The basic results to be found within are of fundamental importance for further study of related problems such as automated synthesis and safety control in cyber-physical systems using formal methods.
Discriminating Data: Correlation, Neighborhoods, and the New Politics of Recognition
by Wendy Hui ChunHow big data and machine learning encode discrimination and create agitated clusters of comforting rage.In Discriminating Data, Wendy Hui Kyong Chun reveals how polarization is a goal—not an error—within big data and machine learning. These methods, she argues, encode segregation, eugenics, and identity politics through their default assumptions and conditions. Correlation, which grounds big data&’s predictive potential, stems from twentieth-century eugenic attempts to &“breed&” a better future. Recommender systems foster angry clusters of sameness through homophily. Users are &“trained&” to become authentically predictable via a politics and technology of recognition. Machine learning and data analytics thus seek to disrupt the future by making disruption impossible. Chun, who has a background in systems design engineering as well as media studies and cultural theory, explains that although machine learning algorithms may not officially include race as a category, they embed whiteness as a default. Facial recognition technology, for example, relies on the faces of Hollywood celebrities and university undergraduates—groups not famous for their diversity. Homophily emerged as a concept to describe white U.S. resident attitudes to living in biracial yet segregated public housing. Predictive policing technology deploys models trained on studies of predominantly underserved neighborhoods. Trained on selected and often discriminatory or dirty data, these algorithms are only validated if they mirror this data. How can we release ourselves from the vice-like grip of discriminatory data? Chun calls for alternative algorithms, defaults, and interdisciplinary coalitions in order to desegregate networks and foster a more democratic big data.
Discursive Design: Critical, Speculative, and Alternative Things (Design Thinking, Design Theory)
by Bruce M. Tharp Stephanie M. TharpExploring how design can be used for good—prompting self-reflection, igniting the imagination, and affecting positive social change.Good design provides solutions to problems. It improves our buildings, medical equipment, clothing, and kitchen utensils, among other objects. But what if design could also improve societal problems by prompting positive ideological change? In this book, Bruce and Stephanie Tharp survey recent critical design practices and propose a new, more inclusive field of socially minded practice: discursive design. While many consider good design to be unobtrusive, intuitive, invisible, and undemanding intellectually, discursive design instead targets the intellect, prompting self-reflection and igniting the imagination. Discursive design (derived from “discourse”) expands the boundaries of how we can use design—how objects are, in effect, good(s) for thinking. Discursive Design invites us to see objects in a new light, to understand more than their basic form and utility. Beyond the different foci of critical design, speculative design, design fiction, interrogative design, and adversarial design, Bruce and Stephanie Tharp establish a more comprehensive, unifying vision as well as innovative methods. They not only offer social criticism but also explore how objects can, for example, be used by counselors in therapy sessions, by town councils to facilitate a pre-vote discussions, by activists seeking engagement, and by institutions and industry to better understand the values, beliefs, and attitudes of those whom they serve. Discursive design sparks new ways of thinking, and it is only through new thinking that our sociocultural futures can change.
Discursive Disruption, Populist Communication and Democracy: The Cases of Hugo Chávez and Donald J. Trump (Routledge Research in Political Communication)
by Elena BlockIn Discursive Disruption, Populist Communication and Democracy, Elena Block explores the links between declining democratic discourses, populist communication, and reflects on the communicative and moral dimensions of populism. Block proposes the concept of discursive disruption to help to identify, analyze and understand the disruptive power of populist speech, turning to the communicative styles of Venezuela’s late President Hugo Chávez and the US’s President Donald J. Trump to illustrate and support this new conceptual and analytical tool. While the mainstream political class and media traditionally sought to manage the processes of political communication, the book contends that they have now been displaced and their role has been undermined. Middle ground politics and journalism have been substituted by the adversarial rhetorical styles of populists, multiplied through multi-fragmented channels, texts and voices. With this book, Block continues her introspection in the conceptual, communicative and mediatic dimensions of populism by adding a perspective that draws on democratic and discursive theories. Discursive Disruption, Populist Communication and Democracy is ideally designed for scholars and professional communicators in political science and communication studies eager to understand the connection between weakening discourses of modern democracy and the pervasiness of confrontational styles of populist communication in contemporary political exchanges.
Discussing Design: Improving Communication and Collaboration through Critique
by Adam Connor Aaron IrizarryReal critique has become a lost skill among collaborative teams today. Critique is intended to help teams strengthen their designs, products, and services, rather than be used to assert authority or push agendas under the guise of "feedback." In this practical guide, authors Adam Connor and Aaron Irizarry teach you techniques, tools, and a framework for helping members of your design team give and receive critique.Using firsthand stories and lessons from prominent figures in the design community, this book examines the good, the bad, and the ugly of feedback. Youâ??ll come away with tips, actionable insights, activities, and a cheat sheet for practicing critique as a part of your collaborative process.This book covers:Best practices (and anti-patterns) for giving and receiving critiqueCultural aspects that influence your ability to critique constructivelyWhen, how much, and how often to use critique in the creative processFacilitation techniques for making critiques timely and more effectiveStrategies for dealing with difficult people and challenging situations
Disease Control Through Social Network Surveillance (Lecture Notes in Social Networks)
by Panagiotis Karampelas Thirimachos Bourlai Reda AlhajjThis book examines modern paradigms of disease control based on social network surveillance applications, including electronic sentinel surveillance and wireless application-based surveillance science. It also highlights topics that integrate statistical and epidemiological sciences with surveillance practice and, in order to reflect the evolution of social networking practices, discusses topics concerning the challenges for surveillance theory and practice. In turn, the book goes a step further by providing insights on how we need to analyse epidemiological trends by following best practices on distinguishing useful information from noise, namely fake news, false reporting of disease incidents and events, etc. At the same time, we need to be able to protect health-focused applications and communication tools via cybersecurity technologies and to ensure that anonymity of reporting and privacy are preserved. In closing, the book discusses the role and impact of social media on disease surveillance, as well as the current role of communities in infectious disease surveillance and control.
Disentangling Participation
by Tone Bratteteig Ina WagnerProviding a critical view on user participation in design, disentangling decision making and power in design, this book uses fieldwork material from two large participatory design projects: one experimental in the field of urban planning, the other a product development project within health care. Addressing power issues in participatory design is critical to providing a realistic view of the possibilities and limitations of participation. Design is decision-making: during a design process a huge number of decisions taken before the designers end up with a design result - an artefact or system. All decisions are a choice between possibilities and selecting one of them and making it concrete as a change in an artefact is a demonstration of the capacity to transform, which is a key aspect of power. Participatory designers are committed to empowering users and facilitating a design process where users are able to take part in all types of decisions. This volume explores the challenges for practitioners of participatory design arising from this commitment by asking what participation really means: who should participate and in which parts of a design process; what does it mean to share power with users; how are decisions to be made in a participatory way and what is it that users participate in? The book provides a conceptual framework for understanding these issues as well as a fresh look at participation.

Disjunctive Programming
by Egon BalasDisjunctive Programming is a technique and a discipline initiated by the author in the early 1970's, which has become a central tool for solving nonconvex optimization problems like pure or mixed integer programs, through convexification (cutting plane) procedures combined with enumeration. It has played a major role in the revolution in the state of the art of Integer Programming that took place roughly during the period 1990-2010. The main benefit that the reader may acquire from reading this book is a deeper understanding of the theoretical underpinnings and of the applications potential of disjunctive programming, which range from more efficient problem formulation to enhanced modeling capability and improved solution methods for integer and combinatorial optimization. Egon Balas is University Professor and Lord Professor of Operations Research at Carnegie Mellon University's Tepper School of Business.
