Book Description
LES CAPTEURS INTELLIGENTS CONSTITUENT SANS NUL DOUTE UNE ETAPE IMPORTANTE DANS L'EVOLUTION DE L'INSTRUMENTATION INDUSTRIELLE. LEUR UTILISATION EN MILIEU INDUSTRIEL EST REELLE, BIEN QUE LIMITEE PAR L'INEXISTENCE D'UNE NORMALISATION OU DE GUIDES DE CONCEPTION DE CAPTEURS INTELLIGENTS. S'INSCRIVANT DANS LA MOUVANCE DES TRAVAUX DU GROUPE CIAME (COMITE INTERPROFESSIONNEL POUR L'AUTOMATISATION ET LA MESURE) ET LES REFLEXIONS DU GROUPE DE TRAVAIL CRAN-AMI (ACTIONNEMENTS ET MESURES INTELLIGENTS) RELATIFS AUX CAPTEURS INTELLIGENTS, CETTE ETUDE TENTE UNE MODELISATION DU CONCEPT DE CAPTEUR INTELLIGENT, DANS UN OBJECTIF D'ETABLISSEMENT D'UN MODELE DE REFERENCE. LA DEMARCHE DE MODELISATION ADOPTEE REPOSE SUR L'ETABLISSEMENT DE CONSTRUCTIONS GENERIQUES AU SENS CIM-OSA ET APPLIQUEES AUX CAPTEURS INTELLIGENTS. UNE APPROCHE FONCTIONNELLE DE MODELISATION EST ADOPTEE, SUIVANT LA METHODE SADT/IDEFO, RESTREINTE A LA VUE FONCTIONNELLE, PERMETTANT DE CONSTRUIRE LA STRUCTURE FONCTIONNELLE DU CAPTEUR INTELLIGENT. L'OUTIL GRILLE EST ENSUITE UTILISE POUR EXPLICITER L'ENSEMBLE DES FLUX D'INFORMATIONS AU SEIN DE CETTE STRUCTURE FONCTIONNELLE. FINALEMENT, LA VALIDATION DYNAMIQUE DE LA STRUCTURE FONCTIONNELLE DU CAPTEUR INTELLIGENT EST REALISEE PAR LA CONSTRUCTION D'UNE SPECIFICATION EXECUTABLE DANS L'ENVIRONNEMENT SPEX. LES CONCEPTS DE MODELISATION SONT APPLIQUES A LA MODELISATION D'UN CAPTEUR INTELLIGENT DE TEMPERATURE, INSPIREE PAR LE DEVELOPPEMENT D'UN PROTOTYPE DE TRANSMETTEUR INTELLIGENT DE TEMPERATURE DANS LE CADRE D'UN TRANSFERT DE TECHNOLOGIE

Book Description
Condition monitoring of machines in non-stationary operations (CMMNO) can be seen as the major challenge for research in the field of machinery diagnostics. Condition monitoring of machines in non-stationary operations is the title of the presented book and the title of the Conference held in Hammamet - Tunisia March 26 – 28, 2012. It is the second conference under this title, first took place in Wroclaw - Poland , March 2011. The subject CMMNO comes directly from industry needs and observation of real objects. Most monitored and diagnosed objects used in industry works in non-stationary operations condition. The non-stationary operations come from fulfillment of machinery tasks, for which they are designed for. All machinery used in different kind of mines, transport systems, vehicles like: cars, buses etc, helicopters, ships and battleships and so on work in non-stationary operations. The papers included in the book are shaped by the organizing board of the conference and authors of the papers. The papers are divided into five sections, namely: Condition monitoring of machines in non-stationary operations Modeling of dynamics and fault in systems Signal processing and Pattern recognition Monitoring and diagnostic systems Noise and vibration of machines The presented book gives the back ground to the main objective of the CMMNO 2012 conference that is to bring together scientific community to discuss the major advances in the field of machinery condition monitoring in non-stationary conditions.

Book Description
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.

Book Description
With the major growth of the world’s population over the past century, as well as rapid urbanisation, people increasingly live in crowded cities. This trend is often accompanied by proliferation of poorly built housing, uncontrolled use of land, occupation of unsafe environments and overstretched services. When a natural hazard strikes such a city many people are vulnerable to loss of life and property. This book explores what these people think and feel about the threats that they face. How do they live with perils ranging from earthquakes to monsoons, from floods to hurricanes, in the 21st century? The authors are drawn from a large range of disciplines: Psychology, Engineering, Geography, Anthropology and Urban Planning. They also reflect on how perils are represented in multiple cultures: the United States, Japan, Turkey, Bangladesh, the United Kingdom and New Zealand. The book therefore not only brings to light the ways that different cultures represent natural hazards but also the different ways in which various disciplines write about living with perils in the 21st century. The book is addressed both to researchers and to organizations involved with risk management and risk mitigation.

Book Description
From environmental management to land planning and geo-marketing, the number of application domains that may greatly benefit from using data enriched with spatio-temporal features is expanding very rapidly. This book shows that a conceptual design approach for spatio-temporal databases is both feasible and easy to apprehend. While providing a firm basis through extensive discussion of traditional data modeling concepts, the major focus of the book is on modeling spatial and temporal information.
