Book excerpt: L'avènement de l'Internet of Things (IoT) soulève diverses problématiques, tant au niveau du développement que du déploiement des applications IoT dans les infrastructures de calculs. Par ailleurs, l'infrastructure de calcul la plus répandue de nos jours est celle du Cloud Computing reposant sur des centres de données centralisés communicants entre eux et avec les utilisateurs par le biais d'équipements réseau monolithiques et peu flexibles. L'importance de revoir ce schéma a été mise en avant dans le but de faire face aux défis d'un environnement IoT, hétérogène, mobile et générant une grande quantité de données exigeant des temps de traitements quasi-instantanés. Le modèle classique de l'IoT amenant les objets IoT à envoyer des informations via leurs passerelles au Cloud, qui ensuite fournit les services aux applications trouve des extensions dans l'approche Fog ou Edge permettant de rapprocher les services des usagers en s'appuyant notamment sur des équipements de calcul et de communication intermédiaires entre les utilisateurs et les centres de données. L'architecture Fog Computing est considérée comme étant l'un des schémas permettant d'exploiter la capacité de calcul et de stockage de l'infrastructure réseau en plus de celle du Cloud pour le déploiement des services IoT au plus près des objets IoT. Cependant, les équipements réseau sont hétérogènes et à faible capacité de calcul, ils couvrent une large zone géographique et doivent faire face à la mobilité des utilisateurs IoT. Tout ceci complexifie le problème du placement et de l'ordonnancement des services dans le but d'optimiser divers paramètres tels que l'énergie consommée, les différents coûts liés au placement et l'amélioration de la qualité de service des applications. L'objectif de notre thèse est de proposer des stratégies de placement de services IoT dans une architecture Fog tout en prenant en compte la nature dynamique de l'environnement apportée par la mobilité des objets IoT, le coût énergétique des infrastructures de calcul et les exigences en qualité de service des applications déployées.

This book was released on 2009-04-09 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: This rigourous and self-contained book describes mathematical and, in particular, stochastic methods to assess the performance of networked systems. It consists of three parts. The first part is a review on probability theory. Part two covers the classical theory of stochastic processes (Poisson, renewal, Markov and queuing theory), which are considered to be the basic building blocks for performance evaluation studies. Part three focuses on the relatively new field of the physics of networks. This part deals with the recently obtained insights that many very different large complex networks - such as the Internet, World Wide Web, proteins, utility infrastructures, social networks - evolve and behave according to more general common scaling laws. This understanding is useful when assessing the end-to-end quality of communications services, for example, in Internet telephony, real-time video and interacting games. Containing problems and solutions, this book is ideal for graduate students taking courses in performance analysis.

Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes the set of forces driving the global financial system toward a period of radical transformation and explores the transformational challenges that lie ahead for global and regional or local banks and other financial intermediaries. It is explained how these challenges derive from the newly emerging post-crisis structure of the market and from shadow and digital players across all banking operations. Detailed attention is focused on the impacts of digitalization on the main functions of the financial system, and particularly the banking sector. The author elaborates how an alternative model of banking will enable banks to predict, understand, navigate, and change the external ecosystem in which they compete. The five critical components of this model are data and information mastering; effective use of applied analytics; interconnectivity and “junction playing”; development of new business solutions; and trust and credibility assurance. The analysis is supported by a number of informative case studies. The book will be of interest especially to top and middle managers and employees of banks and financial institutions but also to FinTech players and their advisers and others.

Available in PDF, EPUB and Kindle. Book excerpt: Today, relevant data are typically delivered to cloud-based servers for storing and analysis in order to extract key features and enable enhanced applications beyond the basic transmission of raw data and to realize the possibilities associated with the impending Internet of Things (IoT). To allow for quicker, more efficient, and expanded privacy-preserving services, a new trend called Fog Computing has emerged: moving these responsibilities to the network's edge. Traditional centralized cloud computing paradigms confront new problems posed by IoT application growth, including high latency, limited storage, and outages due to a lack of available resources. Fog Computing puts the cloud and IoT devices closer together to address these issues. Instead of sending IoT data to the cloud, the fog processes and stores it locally at IoT devices. Unlike the cloud, fog-based services have a faster reaction time and better quality overall. Fog Computing, Cloud Computing, and their connectivity with the IoT are discussed in this book, with an emphasis on the advantages and implementation issues. It also explores the various architectures and appropriate IoT applications. Fog Computing, Cloud Computing, and Internet of Things are being suggested as potential research directions. Features: A systematic overview of the state-of-the-art in Cloud Computing, Fog Computing, and Internet of Things Recent research results and some pointers to future advancements in architectures and methodologies Detailed examples from clinical studies using several different data sets

Book excerpt: This prayer book was written over a two-year span. The prayers started one night when my daughter and I could not sync our time to pray together on one particular night in March 2017. While preparing for bed, the Lord said to me, "Just write a prayer and put it on Facebook". I did and the rest is history. You are now holding what it is that the Lord has done with these prayers. Each night with the exception of being away from home with no phone service, or during times of fasting, I wrote a prayer each night and posted them on Facebook. I have been told by many people along the way that they do not know how to pray. It is my prayer that this book will be a foundation for those who feel that they do not know how to pray or who simply need a prayer devotional.

Available in PDF, EPUB and Kindle. Book excerpt: This report provides the most comprehensive and rigorous analysis of Iraqi income and expenditure in several decades. The report makes extensive use of the Iraq Household Socio-Economic Survey, the first nationwide income and expenditure survey since 1988. IHSES data is complemented income and expenditure data from a wide range of other measures of living standards, allowing us to analyze living standards in a holistic way. The analysis presented here was performed with two main goals first, to inform the Government s Poverty Reduction Strategy; and second, to serve as a baseline for future assessments of changes in living standards and the identification of critical issues for deeper examination. Iraqi living standards have two unusual characteristics. First, they have fallen over the past generation. Second, they feature surprisingly little inequality. These characteristics are both rooted in Iraq s recent history of authoritarian government, war, military occupation, insurgency, and civil strife leading to infrastructure destruction and population displacement. There have been few opportunities for individuals to prosper from professional or entrepreneurial activities. Decades of neglected investment have resulted in deterioration of social services and economic infrastructure. Consequently, individuals have lacked capabilities to prosper and an investment climate conducive to prosperity. School enrollment and life expectancy have declined. Extremely low returns to education reflect the combination of poor educational quality and lack of employment opportunities. In terms of economic infrastructure, access to reliable electricity and water, and even access to paved roads are low, are further reflections of decades of neglect. While the upper end of the distribution has been pulled down by a lack of opportunities, the lower end has been supported by direct government provision of food. The Public Distribution System (PDS) provides 85 percent of food needs. While PDS has been useful as a safety net for the poor and the vulnerable, the system is expensive, inefficient, and fiscally risky. Indeed, PDS food rations account for a far greater share of public spending than does education or health. Going forward, Iraq faces two main challenges. First, although Iraq does not have to develop from scratch, it faces a formidable challenge in re-development. Second, a shift by the Government is required from direct provision of basic subsistence toward investment in human capacities. The Government can provide an enabling environment through investments in economic infrastructure and services to business and citizens, thus allowing the population to make productive use of education and their own labor. Both challenges are now being taken up by the Poverty Reduction Strategy, which articulates a detailed set of required actions and outlines priorities for government spending.
