Earth Observation Data Analytics Using Machine and Deep Learning: Modern tools, applications and challenges covers the basic properties, features and models for Earth observation (EO) recorded by very high-resolution (VHR) multispectral, hyperspectral, synthetic aperture radar (SAR), and multi-temporal observations.

Caching enables the storage of Internet-based content, including web objects, videos and software updates. When web objects are downloaded from the Internet or across wide-area-network (WAN) links, edge caching stores them at the edge of the network. Content can also be proactively cached at the edge based on its predicted popularity. When subsequent requests come for cached material, the content is quickly delivered from edge caching, without the need to download the data again over the WAN. The result is the ability to help save bandwidth, particularly at times of peak network load, increase content delivery, and provide users with a faster and better network experience.

E-learning has become an important part of our educational life with the development of e-learning systems and platforms and the need for online and remote learning. ICT and computational intelligence techniques are being used to design more intelligent and adaptive systems. However, the art of designing good real-time e-learning systems is difficult as different aspects of learning need to be considered including challenges such as learning rates, involvement, knowledge, qualifications, as well as networking and security issues. The earlier concepts of standalone integrated virtual e-learning systems have been greatly enhanced with emerging technologies such as cloud computing, mobile computing, big data, Internet of Things (IoT), AI and machine learning, and AR/VT technologies.

Electrodynamic Theory of Superconductors is the first book of its kind. It gives a unified and comprehensive theoretical treatment of electromagnetic, thermal and mechanical phenomena in superconductors. Basic concepts and principles in continuum electrodynamics are introduced, with particular emphasis on methodology. Electrodynamic models are developed to study magnetoelastic and thermoelastic superconductors. The author also introduces phenomenological London theory, Cinzburg-Landau theory, electrodynamic models for superconducting thin films, AC losses and Josephson junctions, and BCS microscopic theory of superconductivity. This book can be used as a post graduate level text and as a reference book for researchers and engineers working in the field of applied superconductivity and related areas.

There are several ways to classify electromagnetic waveguides. Depending on their boundaries, they can be classified into waveguides with perfectly reflecting walls or finite impedance walls, as well as open waveguides. In terms of their applications, there are the low attenuation and low delay distortion waveguides for telecommunication, the low crosspolar field waveguides used as feeds for reflector antennas in frequency reuse schemes, as well as the leaky feeders in continuous access communication systems. There are also the natural waveguides such as tunnels and the earth-ionosphere waveguide.

The latest advances in several emerging technologies such as AI, blockchain, privacy-preserving algorithms used in localization and positioning systems, cloud computing and computer vision all have great potential in facilitating social distancing. Benefits range from supporting people to work from home to monitoring micro- and macro- movements such as contact tracing apps using Bluetooth, tracking the movement and transportation level of a city and wireless positioning systems to help people keep a safe distance by alerting them when they are too close to each other or to avoid congestion. However, implementing such technologies in practical scenarios still faces various challenges.

The Internet of Things (IoT) - the emerging global interconnection of billions of 'smart' devices - will be collecting increasing amounts of private and sensitive data about our lives, and will require increasing degrees of reliability and trustworthiness in terms of the levels of assurance provided with respect to confidentiality, integrity and availability. This book examines these important security considerations for the IoT.
