Fiber-based access is recognized as the most promising technology for solving broadband bandwidth bottlenecks. Time division multiplexing passive optical networks (TDM-PONs) that are passive and non-reconfigurable are currently the most widely deployed type of fiber access networks. However, due to their passive nature, TDM-PONs faces several limitations such as inflexible service area coverage, lack of intelligence for control, and inability to counteract security attacks. In order to address the current limitations of optical access networks, we propose reconfigurable technologies for next generation PONs. Two novel reconfigurable technologies are proposed, analyzed, and experimentally evaluated. The first solution is a reconfigurable power-and wavelength- assignment technology based on a novel non-volatile, reconfiguration node. The proposed remote node can reconfigure the network to adapt it to varying degrees of deployment conditions and/or network attacks. Moreover, the proposed remote node incorporates a novel quasi-passive device that does not consume energy once it is reconfigured into a new latching state. Therefore, the proposed remote node has very low energy consumption and does not require local power supply to preserve the passive character of the distribution network. In particular, two novel quasi-passive optical power splitter technologies based on Micro-Electro-Mechanical Systems (MEMS) and transition metal oxide have been designed for the reconfigurable device. A simulation study shows the proposed reconfigurable device would outperform traditional passive splitter in terms of maximum number of supportable users under realistic deployment conditions. The second solution addresses the issue of reconfigurable network consolidation and infrastructure simplification. Current TDM-PONs suffers from limited reach and split-ratio. To enhance the performance in terms of service range and quality of service, reconfigurable network consolidation is a promising solution. It can also simplify the network and reduce cost. We propose the following novel reconfigurable technologies for consolidation and simplification of next generation access networks: (1) Passive reach-extension technology for the drop section of optical access networks; (2) Sleep mode ONUs for energy saving; (3) Centrally managed optical signature that can monitor and protect the upstream link; and (4) Multi-rate burst mode receivers. These reconfigurable technologies can bring the intelligence into optical access networks and improve the efficiency and flexibility for next generation optical access networks.

Language Integrated Query (LINQ) is Microsoft's new technology for powerful, general purpose data access. This technology provides a fully-integrated query language, available in both C# 3.0 and VB 9.0, for high-level data access against objects, relational databases, and XML documents. In this Short Cut you'll learn about LINQ and the proposed C# 3.0 extensions that support it. You'll also see how you can use LINQ and C# to accomplish a variety of tasks, from querying objects to accessing relational data and XML. Best of all, you'll be able to test the examples and run your own code using the latest LINQ CTP, available free from Microsoft. This Short Cut includes a complete reference to the standard LINQ query operators.

IT technology engineering changes everyday life, especially in Computing and Communications. The goal of this book is to further explore the theoretical and practical issues of Future Computing and Communications. It also aims to foster new ideas and collaboration between researchers and practitioners.

China’s bond market is destined to play an increasingly important role, both at home and abroad. And the inclusion of the country’s bonds in global indexes will be a milestone for its financial market integration, bringing big opportunities as well as challenges for policymakers and investors alike. This calls for a good understanding of China’s bond market structure, its unique characteristics, and areas where reforms are needed. This volume comprehensively analyzes the different segments of China’s bond market, from sovereign, policy bank, and credit bonds, to the rapidly growing local government bond market. It also covers bond futures, green bonds, and asset-backed securities, as well as China’s offshore market, which has played a major role in onshore market development.

This book constitutes the refereed proceedings of the 26th IFIP TC 11 International Information Security Conference, SEC 2011, held in Lucerne, Switzerland, in June 2011. The 24 revised full papers presented together with a keynote talk were carefully reviewed and selected from 100 submissions. The papers are organized in topical sections on malware, information flow and DoS attacks, authentication, network security and security protocols, software security, policy compliance and obligations, privacy attacks and privacy-enhancing technologies, risk analysis and security metrics, and intrusion detection.

Co-editors of the volume are: Federico Álvarez, Alessandro Bassi, Michele Bezzi, Laurent Ciavaglia, Frances Cleary, Petros Daras, Hermann De Meer, Panagiotis Demestichas, John Domingue, Theo G. Kanter, Stamatis Karnouskos, Srdjan Krčo, Laurent Lefevre, Jasper Lentjes, Man-Sze Li, Paul Malone, Antonio Manzalini, Volkmar Lotz, Henning Müller, Karsten Oberle, Noel E. O'Connor, Nick Papanikolaou, Dana Petcu, Rahim Rahmani, Danny Raz, Gaël Richards, Elio Salvadori, Susana Sargento, Hans Schaffers, Joan Serrat, Burkhard Stiller, Antonio F. Skarmeta, Kurt Tutschku, Theodore Zahariadis The Internet is the most vital scientific, technical, economic and societal set of infrastructures in existence and in operation today serving 2.5 billion users. Continuing its developments would secure much of the upcoming innovation and prosperity and it would underpin the sustainable growth in economic values and volumes needed in the future. Future Internet infrastructures research is therefore a must. The Future Internet Assembly (FIA) is a successful conference that brings together participants of over 150 research projects from several distinct yet interrelated areas in the European Union Framework Programme 7 (FP7). The research projects are grouped as follows: the network of the future as infrastructure connecting and orchestrating the future Internet of people, computers, devices, content, clouds and things; cloud computing, Internet of Services and advanced software engineering; the public-private partnership projects on Future Internet; Future Internet Research and Experimentation (FIRE). The 26 full papers included in this volume were selected from 45 submissions. They are organized in topical sections named: software driven networks, virtualization, programmability and autonomic management; computing and networking clouds; internet of things; and enabling technologies and economic incentives.

Science-fiction author William Gibson is famously quoted as saying, “The future is already here – it's just not very evenly distributed.” During the Covid pandemic, telehealth and remote monitoring were elevated from interesting innovations to essential tools in many healthcare systems, but not all countries had the infrastructure necessary to pivot quickly, amply demonstrating the negative consequences of the digital divide. This book presents the proceedings of MedInfo 2023, the 19th World Congress on Medical and Health Informatics, held from 8 – 12 July 2023 in Sydney, Australia. This series of biennial conferences provides a platform for the discussion of applied approaches to data, information, knowledge, and wisdom in health and wellness. The theme and title of MedInfo 2023 was The Future is Accessible, but the digital divide is a major concern for health and care-informatics professionals, whether because of global economic disparities, digital literacy gaps, or limited access to reliable information about health. A total of 935 submissions were received for the conference, of which 228 full papers, 43 student papers and 117 posters were accepted following a thorough peer-review process involving 279 reviewers. Topics covered include: information and knowledge management; quality, safety and outcomes; health data science; human, organizational and social aspects; and global health informatics. Significant advances in artificial intelligence, machine learning, augmented reality, virtual reality, and genomics hold great hope for future healthcare planning, delivery, management, education, evaluation, and research, and this book will be of interest to all those working to not only exploit the benefits of these technologies, but also to identify ways to overcome their associated challenges.
