This volume serves as an essential resource to understand the diverse ways in which Covid-19 impacted our societies, including the capacity to innovate, advances in technology, the evolution of the healthcare systems, business model innovation, the prospects of growth, the stability of political systems, and the future of education.

Addressing the rising security issues during the design stages of cyber-physical systems, this book develops a systematic approach to address security at early design stages together with all other design constraints. Cyber-attacks become more threatening as systems are becoming more connected with the surrounding environment, infrastructures, and other systems. Security mechanisms can be designed to protect against attacks and meet security requirements, but there are many challenges of applying security mechanisms to cyber-physical systems including open environments, limited resources, strict timing requirements, and large number of devices. Designed for researchers and professionals, this book is valuable for individuals working in network systems, security mechanisms, and system design. It is also suitable for advanced-level students of computer science.

Turbo coding principles have found widespread applications in information theory and, in part, have entered into mainstream telecommunication theory and practice. These principles are used in error control, detection, interference suppression, equalization, and other communications-related areas. Turbo Codes: Principles and Applications is intended for use by advanced level students and professional engineers involved in coding and telecommunication research. The material is organized into a coherent framework, starting with basic concepts of block and convolutional coding, and gradually increasing in a logical and progressive manner to more advanced material, including applications. All algorithms are fully described and supported by examples, and evaluations of their performance are carried out both analytically and by simulations. The book includes new and original material on a bidirectional SOVA decoding algorithm, design of turbo codes based on the distance spectrum, design of code-matched interleavers, performance on fading channels, and a turbo trellis code modulation scheme. Trellis-based and iterative decoding algorithms, along with a comparison of algorithms based on their performance and complexity, are discussed. Various practical aspects of turbo coding, such as interleaver design, turbo codes on fading channels, and turbo trellis-coded modulation, are presented. Turbo Codes: Principles and Applications will be especially useful to practicing communications engineers, researchers, and advanced level students who are designing turbo coding systems, including encoder/decoder and interleavers, and carrying out performance analysis and sensitivity studies.

This monograph is intended for the designers and would-be designers of secure and efficient wireless communication systems under intentional interference. Along with the widespread of wireless devices, especially reconfigurable software defined radios, jamming has become a serious threat to civilian communications. In this book, going beyond traditional communication system design that mainly focuses on accurate information transmission under benign environments, we aim to enhance the physical layer security of communication systems by integrating modern cryptographic techniques into transceiver design, so as to achieve secure high-speed transmission under hostile interference with high reliability and efficiency. We revisit existing jamming patterns, and introduce new jamming patterns. We analyze the weaknesses of existing anti-jamming techniques. We present innovative and feasible anti-jamming techniques, which can strengthen the inherent security of the 3G, 4G and the upcoming 5G systems with minimal and inexpensive changes to the existing CDMA, frequency hopping and OFDM schemes. We also provide benchmarks for system performance evaluation under various jamming scenarios through capacity analysis. This book includes design principles, in-depth theoretical analysis and practical design examples, and will be of interest to academic researchers as well as professionals in industry.

It addresses the end-to-end protocol stack, satellite design principles, QoS methodologies and international standards for building satellite network systems for multimedia applications.

In order for information systems supporting two different organizations to interoperate, there must be an agreement as to what the words mean. There are many such agreements in place, supporting information systems interoperation in many different application areas. Most of these agreements have been created as part of diverse systems development processes, but since the advent of the Semantic Web in the late 1990s, they have been studied as a kind of software artifact in their own right, called an ontology, or description of a shared world. This book brings together developments from philosophy, artificial intelligence and information systems to formulate a collection of functional requirements for ontology development. Once the functional requirements are established, the book looks at several ontology representation languages: RDFS, OWL, Common Logic and Topic Maps, to show how these languages support the functional requirements, what deficiencies there are, and how the languages relate to each other. Besides a collection of running examples used throughout the book, the entire treatment is supported by an extended example of a hypothetical ontology for the Olympic Games presented first as a set of chapter-end exercises and then as a set of solutions which illustrate the various points made in the text in the context of a single coherent development.

A welcome addition to Palgrave's Global Media Policy and Business series, Internet Governance and the Global South documents the role of the global south in Internet policymaking and challenges the globalization theories that declared the death of the state in global decision-making. Abu Bhuiyan argues that the global Internet politics is primarily a conflict between the states - the United States of America and the states of the global south - because the former controls Internet policymaking. The states of the global south have been both oppositional and acquiescing to the sponsored policies of the United States on Internet issues such as digital divide, multilingualism, intellectual property rights and cyber security. They do not oppose the neoliberal underpinnings of the policies promoted by the United States, but ask for an international framework to govern the Internet so that they can work as equal partners in setting norms for the global Internet.
