Fog Computing for Intelligent Cloud IoT Systems
FOG COMPUTING FOR INTELLIGENT CLOUD IOT SYSTEMSTHIS BOOK IS A COMPREHENSIVE GUIDE ON FOG COMPUTING AND HOW IT FACILITATES COMPUTING, STORAGE, AND NETWORKING SERVICESFog computing is a decentralized computing structure that connects data, devices, and the cloud. It is an extension of cloud computing and is an essential concept in IoT (Internet of Things), as it reduces the burden of processing in cloud computing. It brings intelligence and processing closer to where the data is created and transmitted to other sources. Fog computing has many benefits, such as reduced latency in processing data, better response time that helps the user’s experience, and security and privacy compliance that assures protecting the vital data in the cloud. It also reduces the cost of bandwidth, because the processing is achieved in the cloud, which reduces network bandwidth usage and increases efficiency as user devices share data in the local processing infrastructure rather than the cloud service. Fog computing has various applications across industries, such as agriculture and farming, the healthcare industry, smart cities, education, and entertainment. For example, in the agriculture industry, a very prominent example is the SWAMP project, which stands for Smart Water Management Platform. With fog computing’s help, SWAMP develops a precision-based smart irrigation system concept used in agriculture, minimizing water wastage. This book is divided into three sections. The first section studies fog computing and machine learning, covering fog computing architecture, application perspective, computational offloading in mobile cloud computing, intelligent Cloud-IoT systems, machine learning fundamentals, and data visualization. The second section focuses on applications and analytics, spanning various applications of fog computing, such as in healthcare, Industry 4.0, cancer cell detection systems, smart farming, and precision farming. This section also covers analytics in fog computing using big data and patient monitoring systems, and the emergence of fog computing concerning applications and potentialities in traditional and digital educational systems. Security aspects in fog computing through blockchain and IoT, and fine-grained access through attribute-based encryption for fog computing are also covered. AUDIENCEThe book will be read by researchers and engineers in computer science, information technology, electronics, and communication specializing in machine learning, deep learning, the cyber world, IoT, and security systems. CHANDAN BANERJEE, PHD, is a professor in the Department of Information Technology, Netaji Subhash Engineering College, West Bengal, India.

Responsive Layouts
Welcome to the book “Responsive Layouts: Flex, Grid and Multi-Column” In this book I explain the three best-known responsive layouts: the Flexbox, the Grid and the Multi-Column layout. Flexbox is a one-dimensional layout that only works in one dimension at a time, either horizontally or vertically. The grid layout is a two-dimensional layout that distributes the elements horizontally and vertically at the same time. The multi-column layout is a special layout for magazines and newspapers, where the text should flow in columns with spacing, rules, etc. I'll explain all the properties and their values and how they affect the distribution of elements on the screen. So let's get started. Hello, I am Abdelfattah Ragab, a professional software developer with more than 20 years of experience.

Mastering Knowledge Management Using Microsoft Technologies
For companies and individuals already using Microsoft365 and other Microsoft technologies, this book is designed to reveal how to fully utilize these platforms for effective Knowledge Management without needing to rely on additional third-party tools. It addresses a common issue where organizations find themselves with overlapping technology capabilities for managing knowledge. This situation arises because many companies are not fully aware of the capabilities they already possess within their existing Microsoft tools. Knowledge management firms capitalize on this gap by offering white-labeled, branded applications with user-friendly interfaces, selling them to companies that could achieve the same results with what they already own, if only they knew how to use them properly. By mastering the use of Microsoft technologies for Knowledge Management, organizations can save significant amounts of money that would otherwise be spent on unnecessary external solutions.Whether your objective is to optimize Knowledge Management processes or align these tools with your organization's business processes, this book is designed to serve as a valuable resource, offering practical guidance and strategies to empower your endeavors.

Linking with Nature in the Digital Age
The use of digital technology in our societies is growing to meet the ever-increasing challenges of data collection, raising awareness, education and understanding nature. Artificial intelligence, for example, appears to be the answer to collecting massive amounts of data on biodiversity at a global scale and facilitating citizen participation in such data collection.Linking with Nature in the Digital Age explores the reconfiguration of our relationship with nature within this digital framework. This book examines this mediated linking from three angles. Firstly, it shows how digital technology can foster the development of links to nature. Then, it describes in greater detail the materiality of these links and how they have evolved with the developments in information technology. Finally, it questions the belief in the digital as a facilitator and opens up new perspectives on our relationship with nature and the living worldÉMILIE KOHLMANN is a lecturer in information and communication sciences at Université Grenoble Alpes, France. As part of the GRESEC laboratory, she works on nature mediation systems.Acknowledgments xi Introduction xiiiÉmilie KOHLMANNPART 1 EXTENDING LINKS THROUGH DIGITAL DEVICES 1Chapter 1 Benchmarks: Biodiversity, Participation and Digital Technology 3Émilie KOHLMANN and Catherine GAUTHIERChapter 2 The Documentary Links of Herbarium Collections and Their Communicative Stakes 15Lisa CHUPINChapter 3 Investigating the Relationship with Nature in the Animation of Wineries' Facebook Pages 35Marie-Caroline HEÏD and Catherine DE LAVERGNEChapter 4 Forms of Linking with Nature and with Others through a Digital Device: "Let Them Know and Participate" 53Émilie KOHLMANNPART 2 LINK MATERIALITY AND STRUCTURE: GENERATING DATA ON NATURE 73Chapter 5 Explainable Artificial Intelligence for a Better Understanding of Naturalist Data 75Ikram CHRAIBI KAADOUDChapter 6 Pooling Biodiversity Databases: Linking Data, Linking Actors 103Camille BERNARDChapter 7 The Challenges and Implementation of the LPO Auvergne-Rhône-Alpes Naturalist Information System 127Daniel THONONPART 3 GAINS AND LOSSES: QUESTIONING THE LINK TO NATURE 149Chapter 8 Complementarity of Big Data and Citizen Participation in Monitoring Plant Biodiversity 151Pierre BONNET, Alexis JOLY and François MUNOZChapter 9 New Automatic Identification Tools: An Aid for Botanists and Nature Managers? 161François MUNOZ and Pierre BONNETChapter 10 The Contribution of New Technologies to Our Experiences of Nature 177Minh-Xuan TRUONGChapter 11 Belonging to the World to Think of the Link: The Relationship with the Natural Environment as a Crucible of Relatedness 191Amélie COULBAUT-LAZZARINIConclusion 209Émilie KOHLMANNList of Authors 215Index 217
