This book constitutes the refereed proceedings of the 9th International Conference on Well-Being in the Information Society, WIS 2022, held in Turku, Finland, in August 2022. The 14 revised full papers presented were carefully reviewed and selected from 17 submissions. The proceedings are structured in four sections as follows: mental well-being and e-health; social media and well-being; innovative solution for well-being in the information society; driving well-being in the information society.

This book constitutes the refereed proceedings of the 15th International Conference on the Quality of Information and Communications Technology, QUATIC 2022, held in Talavera de la Reina, Spain, in September 2022.The 18 full papers and 3 short papers were carefully reviewed and selected from 54 submissions. The papers are organized in topical sections: smart and advanced systems; verification and validation; skills and education; industrial experiences and applications; safety, security and privacy.

This book presents a detailed pedagogical description of the 5G commercial wireless communication system design, from an end to end perspective. It compares and contrasts NR with LTE, and gives a concise and highly accessible description of the key technologies in the 5G physical layer, radio access network layer protocols and procedures. This book also illustrates how the 5G core and EPC is integrated into the radio access network, how virtualization and edge computer fundamentally change the way users interact with the network, as well as 5G spectrum issues.This book is structured into six chapters. The first chapter reviews the use cases, requirements, and standardization organization and activities for 5G. These are 5G requirements and not NR specifically, as technology that meets the requirements, may be submitted to the ITU as 5G technology. This includes a set of Radio Access Technologies (RATs), consisting of NR and LTE; with each RAT meeting different aspects of the requirements. The second chapter describes the air interface of NR and LTE side by side. The basic aspects of LTE that NR builds upon are first described, followed by sections on the NR specific technologies, such as carrier/channel, spectrum/duplexing (including SUL), LTE/NR co-existence and new physical layer technologies (including waveform, Polar/LDPC codes, MIMO, and URLLC/mMTC). In all cases the enhancements made relative to LTE are made apparent. The third chapter contains descriptions of NR procedures (IAM/Beam Management/Power control/HARQ), protocols (CP/UP/mobility, including grant-free), and RAN architecture. The fourth chapter includes a detailed discussion related to end-to-end system architecture, and the 5G Core (5GC), network slicing, service continuity, relation to EPC, network virtualization, and edge computing. The fifth and major chapter describes the ITU submission and how NR and LTE meet the 5G requirements in significant detail, from the rapporteur responsible for leading the preparation and evaluation, as well as some field trial results.Engineers, computer scientists and professionals with a passing knowledge of 4G LTE and a comprehensive understanding of the end to end 5G commercial wireless system will find this book to be a valuable asset. Advanced-level students and researchers studying and working in communication engineering, who want to gain an understanding of the 5G system (as well as methodologies to evaluate features and technologies intended to supplement 5G) will also find this book to be a valuable resource.

This book constitutes the refereed proceedings of the 17th International Workshop on Security, IWSEC 2022, which took place as a hybrid event in Tokyo, Japan, in August/September 2022. The 12 full papers presented in this book were carefully reviewed and selected from 34 submissions. They were organized in topical sections as follows: mathematical cryptography; system security and threat intelligence; symmetric-key cryptography; post-quantum cryptography; advanced cryptography. 

This book constitutes the proceedings of the 33rd International Conference on Parallel and Distributed Computing, Euro-Par 2022, held in GLasgow, UK, in August 2022.The 25 full papers presented in this volume were carefully reviewed and selected from 102 submissions. The conference Euro-Par 2022 covers all aspects of parallel and distributed computing, ranging from theory to practice, scaling from the smallestto the largest parallel and distributed systems, from fundamental computational problems and models to full-fledged applications, from architecture and interface design and implementation to tools, infrastructures and applications.  

This book constitutes the refereed proceedings of the 52nd International Simulation and Gaming Association Conference, ISAGA 2021, held in Indore, India, during September 6-10, 2021.  The 24 full papers included in this book were carefully reviewed and selected from 58 submissions. They were organized in topical sections as follows: game design and facilitation; gaming in education; player experience in simulations; and policy formulation and serious games.
