Enterprise interoperability VI : Interoperability for agility, resilience, and plasticity of collaborations by Kai Mertins( Book )

1 edition published in 2014 in English and held by 3 WorldCat member libraries worldwide

A concise reference to the state of the art in systems interoperability, Enterprise Interoperability VI will be of great value to engineers and computer scientists working in manufacturing and other process industries and to software engineers and electronic and manufacturing engineers working in the academic environment. Over 40 papers, ranging from academic research through case studies to industrial and administrative experience of interoperability show how, in a scenario of globalised markets, where the capacity to cooperate with other firms efficiently starts to become essential in order to remain in the market in an economically, socially and environmentally cost-effective manner, the most innovative enterprises are beginning to redesign their business model to become interoperable. This goal of interoperability is essential, not only from the perspective of the individual enterprise but also in the new business structures that are now emerging, such as supply chains, virtual enterprises, interconnected organisations or extended enterprises, as well as in mergers and acquisitions. Establishing efficient and relevant collaborative situations requires to manage interoperability on a dynamic point of view: a relevant and efficient collaboration of organizations might require adaptation to remain in line with potentially changing objectives, potentially evolving resources, unexpected events, etc. Many of the papers contained in this, the seventh volume of Proceedings of the I-ESA Conferences have examples and illustrations calculated to deepen understanding and generate new ideas. The I-ESA14 Conference from which this book is drawn was organized by Ecole Nationale Superieure des Mines dAlbi-Carmaux, on behalf the European Virtual Laboratory for Enterprise Interoperability (INTEROP-VLab) and sponsored by the International Federation for Information Processing (IFIP)

Étude de la granulation humide de poudres cosmétiques par assiette granulatrice et mélangeur à haut cisaillement by Florence Cordier( Book )

2 editions published in 2000 in French and held by 3 WorldCat member libraries worldwide

Deux procédés de granulation en voie humide d'une même couple poudre-liant ont été étudiés : une assiette granulatrice et un mélangeur granulateur à taux de cisaillement élevé. Nous avons mis en œuvre des expériences de granulation et des tests de caractérisation afin de cerner expérimentalement les phénomènes qui gouvernent la formation des granules dans ces appareils. Les caractéristiques des granules sous forme de bilan de population en taille, en porosité et en composition ont été étudiés en fonction des paramètres de fonctionnement des appareils. Cela nous a permis de mettre en évidence les différents mécanismes conduisant à la formation des granules. Enfin, une comparaison entre les deux appareils est effectuée dans le but de choisir le procédé optimal pour la fabrication de granules de propriétés données
Amélioration de la solubilité de principes actifs BCS classe 2 par obtention de dispersions solides by Camille Nadaud( Book )

2 editions published in 2016 in French and held by 2 WorldCat member libraries worldwide

En raison de leur complexité croissante, la solubilité des nouvelles entités chimiques en milieu aqueux est de plus en plus faible. Ainsi, le développement de beaucoup de principes actifs échoue à cause d'une hydrosolubilité insuffisante. De nombreuses technologies existent pour améliorer la solubilité et/ou solubilisation de tels composés. Cette thèse est ciblée sur la formulation de dispersions solides amorphes par extrusion à chaud. En particulier, un principe actif d'intérêt industriel sera formulé en utilisant une extrudeuse bi-vis disponible sur la plateforme Gala®. Cette technologie autorise l'utilisation d'un grand nombre de matrices, ce qui peut nécessiter un grand nombre d'essais expérimentaux. Une attention particulière est donc portée à l'utilisation de méthodes prédictives de la miscibilité entre les composants qui peuvent ainsi permettre une première sélection des matrices. Sur la base de ces résultats, une étude sur le procédé de hot melt extrusion a ensuite été réalisée
Composites à fibres de carbone recyclées : variabilité des sources et optimisation des performances mécaniques by Sabrine Jlassi( )

2 editions published in 2019 in French and held by 2 WorldCat member libraries worldwide

There is a great deal of interest with carbon fiber reinforced composite recycling in order to respond to regulatory requirements and industrial needs. The major challenge is to recover carbon fibers in order to reintegrate them into second-generation (2.0) composites. The particularity of recycled carbon fibers coming from different sources is the variability of their properties. From an industrial and economical point of view, composite sorting by fiber type/grade before recycling seems to be not profitable. This project aims to evaluate the interest of recycling composites by steam-thermolysis without preliminary sorting and to validate at a representative scale the implementation conditions of recycled fibers into textile reinforcements and 2.0 thermoplastic composites. The study focused on development and mechanical characterization of new virgin carbon fiber non-woven reinforced composites. A design of experiments was carried out by using a Mixture Design methodology considering three carbon fiber grades cut into three different lengths in order to produce non-woven reinforcement by carding. It has been shown that the mixture of fibers with different properties and lengths induces reducing variability of composite properties. But the increase in mixture proportion of fibers having low mechanical properties leads to a drop-in composite performance. This part allowed a better understanding of fiber properties and non-woven reinforcement architecture influence on composite properties. The study was completed by a comparison of mechanical properties of two simple and comingled recycled carbon fiber non-woven reinforced composites. The results showed an excellent potential of recycled carbon fiber non-woven reinforcement compared to virgin carbon fiber and commercialized recycled carbon fiber non-wovens
Experimental study and modeling of hydrodynamic and heating characteristics of flighted rotary kilns by Alex Stéphane Bongo Njeng( Book )

2 editions published in 2015 in English and held by 2 WorldCat member libraries worldwide

The present work addresses a fundamental study on flighted rotary kilns. They are gas-solid reactors, used in a variety of industries to process heterogeneous media. However, operating these kilns mainly relies on the know-how of operators due to insufficient fundamental understanding. The aim of this work is to provide engineers with relevant tools and models to assist in the design stage and the performance improvement of existing operating process units, in particular indirectly heated rotary kilns, inclined and equipped with lifters. In the first part, we studied the effects of operating parameters on the flow of materials of differing properties and shape. For this purpose, residence time distribution measurements were performed through experimental stimulus response tests. Two pilot-scale rotary kilns with similar length-to-diameter ratios, but a dimension ratio of about two were used in this study. We focused on the effects of lifter shape and configurations. The effects of the rotational speed, the kiln slope, the mass flow rate and the exit dam height were also analyzed. The flow of solids was quantitatively characterized primarily by the experimental mean residence time, hold-up, and axial dispersion coefficient. Using a dimensional analysis, models were established to predict the mean residence time, the filling degree and the axial dispersion coefficient, providing basic information on the kiln design, solid particle properties and operating conditions. In the second part, we studied the heat transfer mechanisms occurring in the flighted rotary kiln by measuring temperature profiles at the wall, the freeboard gas and the bulk of solids. Analysis of the temperature profiles focused on two main issues: assessment of the heat transfer coefficient between wall and gas, and assessment of the heat transfer coefficient between wall and solid particles. The lumped system analysis and a heat balance using the power supplied for the heating were applied to determine the experimental heat transfer coefficients. The effects of operating conditions and lifting flights were analyzed. Both heat transfer coefficients were then correlated through dimensional considerations. Lastly a global dynamic model mainly based on the models developed in this study can be used to determine wall, gas and bulk solids axial temperature profiles in an indirectly heated flighted rotary kiln. This global model needs to be completed with specific models related to a reaction so as to be used as a framework for the simulation of specific industrial rotary kilns
Proposition d'un cadre méthodologique pour le management de la continuité d'activité : application à la prise en charge à domicile by Olfa Rejeb( Book )

2 editions published in 2013 in French and held by 2 WorldCat member libraries worldwide

In the present context, Information and Communication technologies are recognized as an inevitable element to improve business practices. Particularly in the home-care field in order to meet challenges of coordination and care continuity. However, these organizations operate in a highly dynamic and uncertain environment. In view of these endogenous and exogenous disruptions, they have to react in an agile way to face risks and to ensure their resilience. The Business Continuity Management (BCM) meets these expectations. Our motivation in this research work is to define a methodological framework to implement the business continuity management within a socio -technical system as an integral part of a new approach to model driven enterprise engineering. After delivering a synthesis of related work to Business Continuity Management, a research question concerning the structuring of this knowledge has been addressed. A methodological framework for business continuity management is then suggested. It is based on (i) the definition and the design of a meta-model integrating BCM and enterprise engineering, (ii) the development of a set criticality assessment matrix to support the business impact analysis, and finally on (iii) the definition of a modeling language adapted to concepts of BCM. A case study from the home-care sector illustrates the foundation of the methodological framework
Sustainable design of oilseed-based biofuel supply chains : the case of Jatropha in Burkina Faso by Arnaud Chapuis( Book )

2 editions published in 2014 in French and English and held by 2 WorldCat member libraries worldwide

The development of biofuel production in Burkina Faso, raises high expectations regarding the development of rural energy access and the substitution of imported fossil fuels. Several initiatives for biofuel production from Jatropha oilseeds were launched in recent year by NGOs and private operators.The government is planning to define a policy framework to support the development of this sector. To this end, the potential benefits from this activity needs to be carefully investigated in regard to sustainable development objectives.The goal of this work was to investigate these opportunities by determining the technical possibilities regarding the context and in what conditions and to what extent they can contribute to sustainable development objectives. The approach was based on the modelling and simulation of production processes coupled with environmental and economic assessment tools. Specific experiments were also led whenever data were not available, as for the determination of the oil yield of a screw press. Economic efficiency was assessed using value chain analysis, which consists in calculating the value added generated by the different activities involved in a supply chain, and the distribution of this value in the form of income to the employees, the supply chain players, the state and the banking institutions. Environmental impacts, including greenhouse gas emissions and fossil energy consumption, are evaluated using a partial life-cycle assessment. The production of three different final products was investigated, i.e. straight vegetable oil (SVO), refined oil aimed to be used for stationary applications (power generation, shaft power, pumping...) and biodiesel dedicated to transportation. The analysis of individual processes allowed to identify the most sensitive parameters at a local level. As a general trend for all processes, the price of feedstock dramatically affects the production cost. For SVO production, the oil recovery and the seeds oil content are of paramount importance. The economic performances of the refining and transesterification processes are largely conditioned by the processing capacity, due to economies of scale, and to a lesser extent by the solution employed for energy supply. In the case of biodiesel production, the price of methanol is also a crucial factor. The developed assessment method was applied to several prospective biofuel supply chains, all relying on the production of Jatropha seeds by smallholders. The results have shown that the method can bring crucial information to policy makers. Based on a seed market price of 100 FCFA/kg, any type of biofuel can be produced in a cost effective way. In some cases, the implementation of advanced technologies for energy supply and by-product valorisation is needed to reach the required production cost. This could also be a solution to increase the price of seeds so as to provide higher incomes to farmers. The production of refined oil for power generation appears to be rather expensive relatively to the target, which imposes large processing scales. Supply chains involving a biodiesel plant supplied by several decentralised SVO plants constitute a solution for addressing at the same time rural energy access and the substitution of fossil fuels. Then the income perceived by the State is directly determined by the value and the profits generated by biofuel producers. Eventually, the environmental impacts related to seed processing, in terms of GHG emissions and fossil energy consumption, is relatively low especially when energy requirements are supplied from a renewable resource. By contrast, the impacts of biodiesel production are systematically impaired by the use of methanol of fossil origin in the process
Étude de la relation microstructure/ténacité d'aciers maraging inoxydables by Charline Le Nué( )

2 editions published in 2017 in French and held by 2 WorldCat member libraries worldwide

The stainless maraging steel MLX17, produced and developed by Aubert & Duval, is a candidate for applications in the field of the aeronautics. This steel possesses a high potential in term of mechanical resistance that exceeds that of the other stainless steels. However, the fracture toughness of this grade proves to be sensitive to the cooling rate after aging, resulting of a dispersal of this property. The research of the scientific origins of the degradation of the fracture toughness by a decrease of the cooling rate (air cooling in comparison to water cooling) is the main objective of this thesis. The microstructure was observed for several aging conditions. An approach using various scales (from micrometric to atomic scale) was necessary because of the complexity of the microstructure. In parallel, the study of tensile mechanical properties and resistance to propagation of cracks was led. The aim was to correlate the mechanical behavior to the microstructural evolution observed for the aging conditions investigated. Microstructural analyses by dilatometry and atomic tomography probe have shown the formation of a complementary precipitation of the hardening phase, responsible of the fracture toughness deterioration. In order to have a better control of this additional precipitation and to make it less fragile, a modification of the aging conditions was proposed. This alternative enabled an improvement of the trade-offs between the high strength and the fracture toughness

Novel fabrication of Alloy 625 and MCrAlY bond coat by laser powder bed fusion and microstructure control by Jiwon Lee( )

2 editions published in 2020 in English and held by 2 WorldCat member libraries worldwide

In this study, Alloy 625 was fabricated by one of the most commonly used additive manufacturing (AM) methods, laser powder bed fusion (L-PBF), and its mechanical properties were evaluated at various temperatures. The L-PBF fabricated Alloy 625 showed high strength and relatively poor elongation. Thus, some heat treatments were applied to improve its performance. A solid-solution heat treatment with a temperature of more than 1000 °C was applied to the L-PBF Alloy 625, resulting in recrystallization because of high energy stored within the alloy attributed by high density of dislocations. This modified microstructure of the L-PBF Alloy 625 sample showed the required strength under tensile testing at room temperature (higher strength than wrought Alloy 625 and greater elongation than L-PBF as-built alloy). In view of enhancing mechanical properties at high temperature, a grain boundary serration (GBS) heat treatment was specifically designed for L-PBF Alloy 625. Because this was the first attempt to produce GBS in a high-Nb-content alloy, it was necessary to understand its mechanism first. To induce GBS, it is necessary for large solute atoms to move near the grain boundaries (GBs). Therefore, the GBS heat treatment was modified for application to the L-PBF Alloy 625. The specially designed GBS heat treatment successfully induced the zigzag patterns of serrated GBs for the first time. This GBS L-PBF Alloy 625 showed improved high-temperature mechanical properties in terms of increased ductility and elimination of the dynamic strain aging (DSA) effect at elevated temperatures. To further improve the high-temperature property of the L-PBF Alloy 625, NiCrAlY bond coat was applied to the Alloy 625 substrate by the same method (L-PBF) for the first time to improve the efficiency of the production process and increase the resistance to oxidation. Although their different thermal properties led to many trials and errors in the manufacturing of the material, the optimal parameters for applying NiCrAlY bond coat deposition by L-PBF were set and verified to assess the potential for the process to be commercialized. The remelting characteristic of L-PBF induced good metallurgical bonding between the substrate and coating, which indicates good stability. The oxidation behavior of the NiCrAlY-coated Alloy 625 was characterized by thermal gravimetric analysis (TGA) and thermal shock testing; the results indicated that the novel coated material had higher resistance to oxidation than bulk Alloy 625. Therefore, the GBS heat treatment together with efficient NiCrAlY coating can greatly improve the high-temperature mechanical properties of L-PBF manufactured Alloy 625
Matériaux à base de phosphates pour le stockage thermique de l'énergie by Abdoul Razac Sane( )

2 editions published in 2017 in French and held by 2 WorldCat member libraries worldwide

Le stockage d'énergie joue un rôle très important dans le secteur énergétique. Concernant le stockage thermique, il est indispensable pour le fonctionnement en continue des centrales solaires à concentration (CSP) ou pour la récupération des chaleurs perdues dans des installations industrielles. Il y a de nos jours un besoin urgent de nouveaux matériaux performants pour remplacer les matériaux conventionnels à base de nitrate pour un fonctionnement à haute température. La présente thèse porte sur le développement de nouveaux matériaux à base de phosphates pour le stockage de la chaleur sensible. C'est la première étude sur l'utilisation des phosphates dans le stockage de la chaleur. Deux approches ont été explorées : le développement des matériaux liquides et des matériaux céramiques monolithiques. Dans la partie des matériaux liquides, l'objectif est de développer des phosphates ayant le même principe de fonctionnement que les sels fondus. Un grand nombre de phosphates a été étudié et les premiers critères d'évaluation sont les températures de fusion, d'évaporation ou de décomposition et la stabilité thermique. Le ternaire M(PO)3 (M = Li, Na, K avec 33,3% molaire de chaque alkali) peut fonctionner à l'état liquide entre 390 et 850°C alors que l'acide polyphosphorique peut fonctionner jusqu'à 200°C (température de solidification restant à déterminer). Concernant les matériaux céramiques, l'étude sur les monolithes de phosphates purs montre des difficultés lors de la mise en forme et la médiocre performance mécanique de ces matériaux. Le travail s'est ensuite focalisé sur les mélanges argileux-sable/phosphates. L'ajout de phosphates est indispensable pour améliorer les propriétés thermiques et mécaniques des céramiques traditionnelles de terre cuite. L'influence de la température de cuisson, la nature des phosphates et la granulométrie des phosphates a été étudié. Les propriétés physiques, thermiques, mécaniques, thermophysiques, thermomécaniques et la stabilité thermique de ces céramiques ont été étudiées entre 30 et 1000°C. Les résultats obtenus ont montré la bonne compétitivité des céramiques à base du mélange argileux-sable/phosphates par rapport aux autres matériaux de stockage thermique solides tels que le béton, les roches naturelles...Le potentiel d'application de ces céramiques a été démontré par des tests de stockage de type thermocline à l'échelle pilote utilisant les meilleurs matériaux monolithiques et de l'air comme fluide caloporteur. Différents paramètres comme la température d'entrée (350 à 850°C) et le débit du fluide caloporteur ont été étudiés pour les deux phases de charge et de décharge. En parallèle, un modèle 1D a été développé avec COMSOL-multiphysics pour simuler des étapes de charges et de décharges. Le modèle décrit les échanges de chaleur entre le solide, l'air et la paroi et tient compte de tous les paramètres liés au stockage thermocline. Les résultats de simulation sont en bon accord avec les données expérimentales obtenues lors des tests à l'échelle pilote. Ce travail a montré de forts intérêts des matériaux à base de phosphates pour le stockage thermique à des différentes gammes de températures couvrant toutes les technologies CSP et la chaleur fatale industrielle
Conception optimale de centrales solaires à concentration : application aux centrales à tour et aux installations "beam down by Olivier Farges( Book )

2 editions published in 2014 in French and held by 2 WorldCat member libraries worldwide

Since the early 40's, world energy consumption has grown steadly. While this energy mainly came from fossil fuel, its use has included an increase in temperatures. It has become urgent to reduce greenhouse gas emissions to halt climate change. In this context, the development of concentrated solar power (CSP) is a promising solution. The scientific community related to this topic has to focus on efficiency enhancement and economic competitiveness of CSP technologies. To this end, this thesis aims at providing an optimal design method applied to central receiver power plants. It takes advantage of methods developed over many years by the research group StaRWest. Both RAPSODEE (Albi), LAPLACE (Toulouse) and PROMES (Odeillo) researchers take an active part in this group. Coupling high performance Monte Carlo algorithms and stochastic optimization methods, the code we developed allows an optimal design of concentrated solar systems. This code is used to highlight the potential of an uncommon type of central receiver plants: reflective towers, also called "beam down" central receiver systems
