Londra, 1854. Il colera devasta la città. Un medico, John Snow, ha l'idea di segnare su una mappa i punti in cui la malattia colpisce con maggiore durezza. Si accorge che l'epicentro è una pompa d'acqua. Chiusa quella, il colera si ritrae. Il nemico è sconfitto. È la prima dimostrazione della potenza dei dati in campo epidemiologico. Ma virus e batteri sono un avversario ostinato. Che torna ad attaccare sotto varie forme, in tempi e luoghi diversi. Ebola, Sars, Mers. Epidemie imparagonabili tra loro, eppure unite da un filo comune. Ogni volta che un patogeno arriva a manifestarsi, si lascia dietro delle informazioni. Dei numeri. Velocità di contagio, pattern di spostamenti, indice di tr...
Viewed in this analysis from a statistical physics perspective, the Internet is perceived as a developing system that evolves through the addition and removal of nodes and links. This perspective permits the authors to outline the dynamical theory that can appropriately describe the Internet's macroscopic evolution. The presence of such a theoretical framework will provide a revolutionary way of enhancing the reader's understanding of the Internet's varied network processes.
This book provides an introduction to the computational and complex systems modeling of the global spreading of infectious diseases. The latest developments in the area of contagion processes modeling are discussed, and readers are exposed to real world examples of data-model integration impacting the decision-making process. Recent advances in computational science and the increasing availability of real-world data are making it possible to develop realistic scenarios and real-time forecasts of the global spreading of emerging health threats. The first part of the book guides the reader through sophisticated complex systems modeling techniques with a non-technical and visual approach, expla...
An in-depth 2008 account on complex connectivity patterns for graduates and researchers in statistical mechanics, mathematical biology and information science.
The study of complex systems is growing rapidly and modelling and simulation tools are an important part of the process.This volume brings together work from a multidisciplinary group of scientists, who are studying a variety of techniques and applications for modelling and simulating complex systems.Building on the success of previous CoSMoS workshops, the work presented covers a range of modelling, simulation and visualisation techniques applied to investigate both biological and socio-technical systems.
Forecasting the future with advanced data models and visualizations. To envision and create the futures we want, society needs an appropriate understanding of the likely impact of alternative actions. Data models and visualizations offer a way to understand and intelligently manage complex, interlinked systems in science and technology, education, and policymaking. Atlas of Forecasts, from the creator of Atlas of Science and Atlas of Knowledge, shows how we can use data to predict, communicate, and ultimately attain desirable futures. Using advanced data visualizations to introduce different types of computational models, Atlas of Forecasts demonstrates how models can inform effective decision-making in education, science, technology, and policymaking. The models and maps presented aim to help anyone understand key processes and outcomes of complex systems dynamics, including which human skills are needed in an artificial intelligence-empowered economy; what progress in science and technology is likely to be made; and how policymakers can future-proof regions or nations. This Atlas offers a driver's seat-perspective for a test-drive of the future.
Nell’agosto 2014 lo scienziato Alessandro Vesespignani riceve una chiamata: un’epidemia senza precedenti sta distruggendo la Guinea, presto contagerà il resto del mondo. Il nome del virus è ormai noto a tutti: Ebola. Vespignani e il suo team si collegano a un supercomputer e, grazie ad algoritmi e simulazioni, riescono a prevedere la diffusione del virus con mesi di anticipo.Predire il futuro è la nostra ossessione sin dall’alba dei tempi. Gli aruspici hanno scrutato per secoli il domani nelle carcasse degli animali, e ancora oggi non riusciamo a fare a meno della divinazione: sapere a che ora sorge il sole o quando ci sarà la prossima eclissi lunare mitiga il nostro senso di spaes...
This book is the culmination of three years of research effort on a multidisciplinary project in which physicists, mathematicians, computer scientists and social scientists worked together to arrive at a unifying picture of complex networks. The contributed chapters form a reference for the various problems in data analysis visualization and modeling of complex networks.
A guide to the basics of information visualization that teaches nonprogrammers how to use advanced data mining and visualization techniques to design insightful visualizations. In the age of Big Data, the tools of information visualization offer us a macroscope to help us make sense of the avalanche of data available on every subject. This book offers a gentle introduction to the design of insightful information visualizations. It is the only book on the subject that teaches nonprogrammers how to use open code and open data to design insightful visualizations. Readers will learn to apply advanced data mining and visualization techniques to make sense of temporal, geospatial, topical, and net...
