3D City Models and urban information: Current issues and perspectivesEuropean COST Action TU0801R. Billen, A.-F. Cutting-Decelle, O. Marina, J.-P. de Almeida, Caglioni M., G. Falquet, T. Leduc, C. Métral, G. Moreau, J. Perret, G. Rabin, R. San Jose, I. Yatskiv and S. ZlatanovaConsidering sustainable development of cities implies investigating cities in a holistic way taking into account many interrelations between various urban or environmental issues. 3D city models are increasingly used in different cities and countries for an intended wide range of applications beyond mere visualization. Could these 3D City models be used to integrate urban and environmental knowledge? How could they be improved to fulfill such role? We believe that enriching the semantics of current 3D city models, would extend their functionality and usability; therefore, they could serve as integration platforms of the knowledge related to urban and environmental issues allowing a huge and significant improvement of city sustainable management and development. But which elements need to be added to 3D city models? What are the most efficient ways to realize such improvement / enrichment? How to evaluate the usability of these improved 3D city models?These were the questions tackled by the COST Action TU0801 "Semantic enrichment of 3D city models for sustainable urban development". This book gathers various materials developed all along the four year of the Action and the significant breakthroughs

This book constitutes selected, revised and extended papers of the 6th International Conference on Geographical Information Systems Theory, Applications and Management, GISTAM 2020, held in Prague, Czech Republic, May 2020. Due to the COVID-19 pandemic the conference was held online. The 9 revised full papers presented were carefully reviewed and selected from 62 submissions. The papers are centered on urban and regional planning; water information systems; geospatial information and technologies; spatio-temporal database management; decision support systems; energy information systems; GPS and location detection.

This book gathers the proceedings of the 1st International Conference on Engineering, Applied Sciences and System Modeling (ICEASSM), a four-day event (18th–21st April 2017) held in Accra, Ghana. It focuses on research work promoting a better understanding of engineering problems through applied sciences and modeling, and on solutions generated in an African setting but with relevance to the world as a whole. The book provides a holistic overview of challenges facing Africa, and addresses various areas from research and development perspectives. Presenting contributions by scientists, engineers and experts hailing from a host of international institutions, the book offers original approaches and technological solutions to help solve real-world problems through research and knowledge sharing. Further, it explores promising opportunities for collaborative research on issues of scientific, economic and social development, making it of interest to researchers, scientists and practitioners looking to conduct research in disciplines such as water supply, control, civil engineering, statistical modeling, renewable energy and sustainable urban development.

This book explores expertise relevant for two working groups of NeDiMAH, a European Science Foundation (ESF) funded Research Networking Programme. It examines mapping methods, procedures, tools, criticism, awareness, challenges and solutions around the concepts of “Space and Time” and “Information Visualization”. The chapters explore digital methods in the representation of natural disasters, industrial design, cultural, and the history of architecture. The conclusions link to related research and present suggestions for further work including representing landscape not just as another 3D model but as historic evolution with specialised tools.

The advancement of modern technology has allowed for impressive developments in manufacturing processes. Out of these developments, 3D printing has emerged as a new method. 3D Printing: Breakthroughs in Research and Practice is a comprehensive reference source for the latest research and advances on 3D printing processes, technologies, and methods. Highlighting emerging perspectives on manufacturing and industrial applications, this book is ideally designed for professionals, practitioners, students, and researchers interested in the latest developments and uses of 3D printing.

This open access book is the first to systematically introduce the principles of urban informatics and its application to every aspect of the city that involves its functioning, control, management, and future planning. It introduces new models and tools being developed to understand and implement these technologies that enable cities to function more efficiently – to become ‘smart’ and ‘sustainable’. The smart city has quickly emerged as computers have become ever smaller to the point where they can be embedded into the very fabric of the city, as well as being central to new ways in which the population can communicate and act. When cities are wired in this way, they have the potential to become sentient and responsive, generating massive streams of ‘big’ data in real time as well as providing immense opportunities for extracting new forms of urban data through crowdsourcing. This book offers a comprehensive review of the methods that form the core of urban informatics from various kinds of urban remote sensing to new approaches to machine learning and statistical modelling. It provides a detailed technical introduction to the wide array of tools information scientists need to develop the key urban analytics that are fundamental to learning about the smart city, and it outlines ways in which these tools can be used to inform design and policy so that cities can become more efficient with a greater concern for environment and equity.

In this book, leading practitioners and academics provide comprehensive coverage and novel insights into blockchains and the token economy. Real world case studies from a wide range of industries provide practical examples of blockchain-based tokens for real estate, logistics, insurance, recruitment, collectibles, reservations, metaverses, and more. The cases show how tokens provide an innovative way to create and transfer value without relying on traditional intermediaries. Readers will better understand the business and social benefits of tokenization, but also its challenges.
