Book Description
Networks as sets of autonomous organisations working together to achieve individual and shared goals are becoming increasingly important across many areas of public administration. The importance of networks is well known but most analysts would agree that we do not know enough about the dynamics and effectiveness of networks in relation to their internal operations. This is a significant problem as security, intelligence, law enforcement and many other agencies are increasingly required to organise in and through networks to provide national security. In this comprehensive analysis, Chad Whelan presents a highly innovative, qualitative study of networks in the field of national security. Developing our understanding of 'organisational networks' in organisational theory, management and public administration, and 'security networks' in criminology and international relations, he presents a multi-disciplinary analysis of network forms of organisation. Whelan puts forward a methodological framework involving five levels of analysis - structural, cultural, policy, technological and relational - with which we can better analyse and understand the dynamics and effectiveness of networks. This framework is applied to public sector networks operating in the field of counter-terrorism in Australia in a way that is highly relevant to researchers and practitioners in many contexts where government departments and agencies, and the private sector, need to work together. Networks and National Security: Dynamics, Effectiveness and Organisation not only advances our knowledge of networks and national security but also assists with the essential tasks of evaluating and managing networks. Written in a clear and accessible style and featuring a wealth of first-hand accounts concerning the inside operations of networks, this book deals with the crucial subject of inter-agency coordination in the important field of national security.

Book Description
Infrastructures in Practice shows how infrastructures and daily life shape each other. Power grids, roads and broadband make modern lifestyles possible – at the same time, their design and day-to-day operation depends on what people do at home and at work. This volume investigates the entanglement of supply and demand. It explains how standards and 'normal' ways of living have changed over time and how infrastructures have changed with them. Studies of grid expansion and disruption, heating systems, the internet, urban planning and office standards, smart meters and demand management reveal this dynamic interdependence. This is the first book to examine the interdependence between infrastructures and the practices of daily life. It offers an analysis of how new technologies, lifestyles and standards become normalised and fall out of use. It brings together diverse disciplines – history, sociology, science studies – to develop social theories and accounts of how infrastructures and practices constitute each other at different scales and over time. It shows how networks and demands are steered and shaped, and how social and political visions are woven into infrastructures, past, present and future. Original, wide-ranging and theoretically informed, this book puts the many practices of daily life back into the study of infrastructures. The result is a fresh understanding of how resource-intensive forms of consumption and energy demand have come about and what is needed to move towards a more sustainable lower carbon future.

Book Description
This volume is a tutorial for the study of dynamical systems on networks. It discusses both methodology and models, including spreading models for social and biological contagions. The authors focus especially on “simple” situations that are analytically tractable, because they are insightful and provide useful springboards for the study of more complicated scenarios. This tutorial, which also includes key pointers to the literature, should be helpful for junior and senior undergraduate students, graduate students, and researchers from mathematics, physics, and engineering who seek to study dynamical systems on networks but who may not have prior experience with graph theory or networks. Mason A. Porter is Professor of Nonlinear and Complex Systems at the Oxford Centre for Industrial and Applied Mathematics, Mathematical Institute, University of Oxford, UK. He is also a member of the CABDyN Complexity Centre and a Tutorial Fellow of Somerville College. James P. Gleeson is Professor of Industrial and Applied Mathematics, and co-Director of MACSI, at the University of Limerick, Ireland.

Book Description
From the Internet to networks of friendship, disease transmission, and even terrorism, the concept--and the reality--of networks has come to pervade modern society. But what exactly is a network? What different types of networks are there? Why are they interesting, and what can they tell us? In recent years, scientists from a range of fields--including mathematics, physics, computer science, sociology, and biology--have been pursuing these questions and building a new "science of networks." This book brings together for the first time a set of seminal articles representing research from across these disciplines. It is an ideal sourcebook for the key research in this fast-growing field. The book is organized into four sections, each preceded by an editors' introduction summarizing its contents and general theme. The first section sets the stage by discussing some of the historical antecedents of contemporary research in the area. From there the book moves to the empirical side of the science of networks before turning to the foundational modeling ideas that have been the focus of much subsequent activity. The book closes by taking the reader to the cutting edge of network science--the relationship between network structure and system dynamics. From network robustness to the spread of disease, this section offers a potpourri of topics on this rapidly expanding frontier of the new science.

Book Description
In this book Kim provides the reader with a reliable method to develop "joined up" strategies and plans for common business situations - a powerful addition to current tools and frameworks. The initial focus is on the core "strategic architecture" of the business, which explains how performance arises from its system of real elements (customers, staff, products, capacity, cash). Later chapters extend the method to deal with the quality and development of customers and other resources, competition, policy decisions, intangible factors and organizational capabilities. The strategy dynamics method deploys the rigorous, scientific method of system dynamics - essentially the application of engineering control theory principles to social systems. The method leads to the creation of working, quantified models of any enterprise, or any part thereof, of any scale, in any sector-or of any issue that such an enterprise may face. Kim uses clear, every-day language, and develops examples demonstrating how to create working, quantified models we need to develop and manage strategy. The book is supported by the Sysdea strategy planning software. Many of Kim's example models are available online for the reader to explore. Sysdea - www.sysdea.com. This version of the book is printed in greyscale. A version with the interior charts etc in color is also available search on - ISBN-13: 978-1512107753 .

Book Description
This book provides a timely and comprehensive study of dynamic resource management for network slicing in service-oriented fifth-generation (5G) and beyond core networks. This includes the perspective of developing efficient computation resource provisioning and scheduling solutions to guarantee consistent service performance in terms of end-to-end (E2E) data delivery delay. Network slicing is enabled by the software defined networking (SDN) and network function virtualization (NFV) paradigms. For a network slice with a target traffic load, the E2E service delivery is enabled by virtual network function (VNF) placement and traffic routing with static resource allocations. When data traffic enters the network, the traffic load is dynamic and can deviate from the target value, potentially leading to QoS performance degradation and network congestion. Data traffic has dynamics in different time granularities. For example, the traffic statistics (e.g., mean and variance) can be non-stationary and experience significant changes in a coarse time granularity, which are usually predictable. Within a long time duration with stationary traffic statistics, there are traffic dynamics in small timescales, which are usually highly bursty and unpredictable. To provide continuous QoS performance guarantee and ensure efficient and fair operation of the network slices over time, it is essential to develop dynamic resource management schemes for the embedded services in the presence of traffic dynamics during virtual network operation. Queueing theory is used in system modeling, and different techniques including optimization and machine learning are applied to solving the dynamic resource management problems. Based on a simplified M/M/1 queueing model with Poisson traffic arrivals, an optimization model for flow migration is presented to accommodate the large-timescale changes in the average traffic rates with average E2E delay guarantee, while addressing a trade-off between load balancing and flow migration overhead. To overcome the limitations of Poisson traffic model, the authors present a machine learning approach for dynamic VNF resource scaling and migration. The new solution captures the inherent traffic patterns in a real-world traffic trace with non-stationary traffic statistics in large timescale, predicts resource demands for VNF resource scaling, and triggers adaptive VNF migration decision making, to achieve load balancing, migration cost reduction, and resource overloading penalty suppression in the long run. Both supervised and unsupervised machine learning tools are investigated for dynamic resource management. To accommodate the traffic dynamics in small time granularities, the authors present a dynamic VNF scheduling scheme to coordinate the scheduling among VNFs of multiple services, which achieves network utility maximization with delay guarantee for each service. Researchers and graduate students working in the areas of electrical engineering, computing engineering and computer science will find this book useful as a reference or secondary text. Professionals in industry seeking solutions to dynamic resource management for 5G and beyond networks will also want to purchase this book.

Book Description
Are all film stars linked to Kevin Bacon? Why do the stock markets rise and fall sharply on the strength of a vague rumour? How does gossip spread so quickly? Are we all related through six degrees of separation? There is a growing awareness of the complex networks that pervade modern society. We see them in the rapid growth of the internet, the ease of global communication, the swift spread of news and information, and in the way epidemics and financial crises develop with startling speed and intensity. This introductory book on the new science of networks takes an interdisciplinary approach, using economics, sociology, computing, information science and applied mathematics to address fundamental questions about the links that connect us, and the ways that our decisions can have consequences for others.
