5G NR: Architecture, Technology, Implementation, and Operation of 3GPP New Radio Standardsis an in-depth, systematic, technical reference on 3GPP's New Radio standards (Release 15 and beyond), covering the underlying theory, functional descriptions, practical considerations and implementation of the 5G new radio access technology. The book describes the design and operation of individual components and shows how they are integrated into the overall system and operate from a systems perspective. Uniquely, this book gives detailed information on RAN protocol layers, transport, network architecture and services, as well as practical implementation and deployment issues, making it suitable for researchers and engineers who are designing and developing 5G systems. Reflecting on the author's 30 plus years of experience in signal processing, microelectronics and wireless communication system design, this book is ideal for professional engineers, researchers and graduate students working and researching in cellular communication systems and protocols as well as mobile broadband wireless standards.
Comprises select peer-reviewed proceedings of the conference IDEA 2022 Broadens understanding in the domains of data structures and data management algorithms, among others Discusses novel theories and research work on data engineering and applications
Depuis la fin du xixe siècle et la mise au point de la bouillie bordelaise, le cuivre est un élément majeur des méthodes de protection des cultures contre diverses maladies (mildious, certaines mycoses et la plupart des bactérioses), en particulier sur vigne, productions fruitières et cultures légumières S’il reste aujourd’hui largement employé dans diverses formes d’agriculture dites « conventionnelles », aux côtés d’autres pesticides, le cuivre joue un rôle crucial dans les systèmes agrobiologiques, car c’est actuellement la seule substance active homologuée en agriculture biologique (AB) ayant à la fois un effet biocide fort et une large gamme d’action Si la plupart des utilisations du cuivre sont justifiées par son efficacité biologique, elles posent des problèmes éco toxicologiques (risques avérés pour les populations microbiennes du sol, les vers de terre, certains organismes aquatiques et des auxiliaires des cultures) La mise en évidence de ces impacts environnementaux du cuivre a motivé des restrictions réglementaires d’usage (plafonnement des doses applicables par hectare et par an), et même son interdiction comme pesticide dans certains pays européens (Pays-Bas, Danemark), ce qui génère des distorsions de concurrence entre pays
While many books explain the how of bitcoin, The Internet of Money delves into the why of bitcoin. Acclaimed information-security expert and author of Mastering Bitcoin, Andreas M. Antonopoulos examines and contextualizes the significance of bitcoin through a series of essays spanning the exhilarating maturation of this technology. Bitcoin, a technological breakthrough quietly introduced to the world in 2008, is transforming much more than finance. Bitcoin is disrupting antiquated industries to bring financial independence to billions worldwide. In this book, Andreas explains why bitcoin is a financial and technological evolution with potential far exceeding the label "digital currency." Andreas goes beyond exploring the technical functioning of the bitcoin network by illuminating bitcoin's philosophical, social, and historical implications. As the internet has essentially transformed how people around the world interact and has permanently impacted our lives in ways we never could have imagined, bitcoin--the internet of money--is fundamentally changing our approach to solving social, political, and economic problems through decentralized technology.

Even for people not working with the Unified Process, the book is still of great use. UML 2 and the Unified Process, Second Edition is a must-read for every UML 2 beginner and a helpful guide and reference for the experienced practitioner."--Roland Leibundgut, Technical Director, Zuehlke Engineering Ltd."This book is a good starting point for organizations and individuals who are adopting UP and need to understand how to provide visualization of the different aspects needed to satisfy it. "--Eric Naiburg, Market Manager, Desktop Products, IBM Rational SoftwareThis thoroughly revised edition provides an indispensable and practical guide to the complex process of object-oriented analysis and design using UML 2. It describes how the process of OO analysis and design fits into the software development lifecycle as defined by the Unified Process (UP).UML 2 and the Unified Process contains a wealth of practical, powerful, and useful techniques that you can apply immediately. As you progress through the text, you will learn OO analysis and design techniques, UML syntax and semantics, and the relevant aspects of the UP. The book provides you with an accurate and succinct summary of both UML and UP from the point of view of the OO analyst and designer.This book providesChapter roadmaps, detailed diagrams, and margin notes allowing you to focus on your needsOutline summaries for each chapter, making it ideal for revision, and a comprehensive index that can be used as a referenceNew to this edition:Completely revised and updated for UML 2 syntaxEasy to understand explanations of the new UML 2 semanticsMore real-world examplesA new section on the Object Constraint Language (OCL)Introductory material on the OMG's Model Driven Architecture (MDA)The accompanying website providesA complete example of a simple e-commerce systemOpen source tools for requirements engineering and use case modelingIndustrial-strength UML course materials based on the book
