Advancements in computational intelligence, which encompasses Artificial Intelligence, Machine Learning, and data analytics, have revolutionized the way we process and analyze biomedical and health data. These techniques offer novel approaches to understanding complex biological systems, improving disease diagnosis, optimizing treatment plans, and enhancing patient outcomes. Computational Intelligence and Blockchain in Biomedical and Health Informatics introduces the role of computational intelligence and blockchain in the biomedical and health informatics fields and provides a framework and summary of the various methods. The book emphasizes the role of advanced computational techniques and offers demonstrative examples throughout. Techniques to analyze the impacts on the biomedical and health Informatics domains are discussed along with major challenges in deployment. Rounding out the book are highlights of the transformative potential of computational intelligence and blockchain in addressing critical issues in healthcare from disease diagnosis and personalized medicine to health data management and interoperability along with two case studies. This book is highly beneficial to educators, researchers, and anyone involved with health data. Machine Learning, on the other hand, takes advantage of methods that allow computers to discover patterns and make predictions without being explicitly programmed to do so. Models are trained using labelled data in supervised learning, while unlabelled data is used in unsupervised learning. Decision trees, support vector machines, and neural networks are all examples of common Machine Learning methods.

Ransomware poses an existential threat to organizations of all sizes in any vertical. These attacks are extremely lucrative, with ransom demands and recovery costs bleeding victim organizations out of millions of dollars. This book provides an overview of the ransomware economy, including the threat that this complex attack ecosystem poses to organizations, and reveals how you can best prepare to be resilient in the face of this threat and remain operational. Ransomware is a major threat to businesses and organizations of all kinds. Ransomware and data extortion attacks are not only disruptive to business operations but also costly to resolve. They spur regulatory actions and civil litigation, including class action lawsuits against victim organizations, and more recently have even resulted in criminal charges being lodged against company officers. A dedicated anti-ransomware solution utilizes Artificial Intelligence (AI) and Machine Learning (ML) with behavioral analytics to identify and stop polymorphic and repacked variants of ransomware that EPP, EDR, and XDR continue to miss. This is because AI/ML endpoint protection models were trained on characteristics that all malware share, including a subset of ransomware.

5G is the fifth generation of cellular technology. It is designed to increase speed, reduce latency, and improve the flexibility of wireless services. 5G New Radio (NR) is the enabler of three key service classes: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low Latency Communications (URLLC), and Massive Machine-Type Communications (mMTC). The 5G network is expected to deliver a wide range of services that includes eMBB, mMTC, and URLLC. To realize such a diverse set of requirements, the 5G network has evolved as a multilayer network that uses various technological advances to offer an extensive range of wireless services. Several technologies, such as software-defined networking, network function virtualization, edge computing, cloud computing, and small cells, are being integrated into the 5G networks to fulfill the need for diverse requirements. This book provides a detailed description of the fundamental aspects of 5G. It gives an in-depth coverage of the network architecture of 5G by considering both the network reference point architecture and the service-based architecture. The MathWorks introduced MATLAB’s 5G Toolbox which provides standard-compliant functions and examples for the simulation of the 5G environment. In this book, functions from the toolbox were used to build the 5G NR end-to-end physical layer model for Packet Data Shared Channel (PDSCH) processing and to calculate the PDSCH throughput, Bit Error Rate (BER), and Block Error Rate (BLER). Moreover, MATLAB models of each block have been used to simulate a complete 5G downlink system.

A biography of Tor—a cultural and technological history of power, privacy, and global politics at the internet's core. Tor, one of the most important and misunderstood technologies of the digital age, is best known as the infrastructure underpinning the so-called Dark Web. But the real “dark web,” when it comes to Tor, is the hidden history brought to light in this book: where this complex and contested infrastructure came from, why it exists, and how it connects with global power in intricate and intimate ways. In Tor: From the Dark Web to the Future of Privacy, Ben Collier has written, in essence, a biography of Tor—a cultural and technological history of power, privacy, politics, and empire in the deepest reaches of the internet. Tor—still known to most as the Dark Web or Dark Net—is not an easy subject to research. It exists on a bizarre terrain, simultaneously in the living rooms of lovely nerds, in the nightmares of police officers, in the small spaces of everyday digital life, and in the corridors of global power. It is a thin and brittle network stretched across the globe like a glass spiderweb and at the same time a profound challenge to the most powerful spy agencies in the world. Most users access Tor in the form of a rather innocuous web browser—much like Chrome, Safari, or Firefox—that rapidly clicks and whirrs through a pleasing set of additional messages before it starts up, giving it a slightly hacker-film feel. Once this is finished and the connection to the Tor network is confirmed, the user can simply browse the internet as normal.

This new volume focuses on design principles for building self-powered AIoT (artificial intelligence of things) applications and their subsequent deployment. The book introduces the futuristic concepts of AIoT by incorporating self-powered systems, firstly by informing the reader of current AI/ML techniques and IoT technologies and then showing the path towards convergence of AI/IoT towards AIoT. The book also explains the many possible diverse applications of AIoT. The combination of IoT for sensing and aggregation of data from the surroundings and AI for analysis and decision-making will expand cyber-physical intelligence towards achieving complete autonomy. However, as the deployment of sensors becomes increasingly ubiquitous, there will be a massive amount of sensor data aggregation and analyses for autonomous decision-making capabilities of AIoT products. This calls for substantial research and product development in self-powered technologies such as energy harvesters, supercapacitors, energy storage devices for energy generation, and energy-efficient technologies such as ultra-low power (ULP) microcontrollers, ULP microprocessors, and ULP smart sensors and actuators. This volume helps to fill that gap. The volume presents research and product development towards structured convergence of self-powered systems, leading to pragmatic R&D deliverables for new products and services. The book is the first of its kind on reporting how the current AI and IoT are progressing toward the vision of AIoT.
