Full textToday, the actors of public health face many challenges related to the ever-changing needs of an aging population and the increasing number of chronic diseases.These needs and the related cost, lead to rethink the care management and rationalize the patient healthcare pathways to make them more efficient.Our thesis work has the following main results.First a general introduction of the health system is presented, followed by an analysis of the evolution of the health system, its principles and its challenges. Next, we provided an overview of trends and organizational innovations in response to these challenges.Secondly, based on a bibliographic, we presented our definitions of pathways (healthcare, health, and life), their relative positioning and their influence on the challenges mentioned above.To model the pathways, we analyzed the concepts mentioned in the preceding definitions and we structured them into a meta-model. Then we used it to enrich an existing enterprise modeling language (GRAI Extended Actigram) and thus obtain a language totally suited to our needs.The latter was used to represent the heathcare processes of two examples of diseases, influenza A (H1N1) and COPD. In the frame of this presentation, methodological aspects were discussed (information resources, translation, etc.).Finally, on the basis of a state-of-the-art of the offered services by current computer platforms, we proposed a methodology for defining value-added services providing an improved access to information and improving the dynamics and efficiency of healthcare based on the modeled healthcare processes

Full textFinancialization of capital would bring industrial firms to maximize shareholder value and would have important effects on strategies. A review of historical and more recent works emphasizes on three main questions : thesis on parasitism, on monopoly and the debate between variety of capitalism and convergence linked to financialization. Empirical evidences on parasitism and monopoly are given on a macro level, then these hypothesis are tested in the case of pharmaceutical sector. An econometrical analysis gives a first partial validation to variety of capitalism and monopoly thesis but rejects parasitism. Then an institutionalist analysis of productive models and regulation confirms these results showing the role of sectorial and political mediations, validating variety of capitalism thesis

Full textIt is now necessary for an agrifood value chain to set-up and develop a coherent sustainability strategy for its various stakeholders and to communicate on the efforts made towards citizens and consumers, in demand for more and more sustainable products. To go beyond the first existing initiatives (specifications, labels, etc.), and effectively increase both their sustainable performance and the perceived quality of their offer, considering new management tools, built jointly between upstream and downstream can be a solution. However, the actors in these chains, with different interests and cultures, have individual visions of sustainability. Therefore, if they want to cooperate in order to improve the sustainable performance of their value chain, they should meet a minimum level of satisfaction for each of them. This work aims to propose new standardized and interoperable management tools for food value chains so that the actors can co-create shared sustainable value and move towards new modes of governance.The experimental context is French pork value chains, whose actors maintain contractual relations and have already tackled joint work on the sustainability of certain products. A first contribution focuses on reflection to build a metric to evaluate the sustainable performance of food value chains. The three following cases are dealing with the possibilities for actors in a food value chain to cooperate on common solutions for sustainability improvement. Contrasted alternative scenarios are compared between them and the results are confronted with the respective expectations of the different actors in the value chain. A fourth section focuses on the importance of standardized data sharing among the various actors to support the sustainable performance. Finally, a final section proposes a support model for participative work in order to facilitate a common strategy definition for sustainability

Full textAbstract: Management scenarios have demanded an increasingly fast decision-making process. To support it, managers and decision-makers must rely on performance and data generation tools to help them to get the assertiveness and accuracy they need to decide. Particularly for production managers of multi products enterprises, this information is not easily obtained due to the complex environment of these firms, made of several and inter-related processes supporting the manufacture of various products. The UEP Method (Production Effort Unit) is a methodology aimed to provide a benchmark to compare production processes performance among different products in a standardized way. This work presents the UEP as an option for providing these performance indicators, also a structure for deploying the tool and a case study of the use of UEP in a multi product healthcare company is presented. Initially, the company had no accurate performance indicators. After applying UEP for a short period of time, the efficacy of the results in supporting the decision-making process was analyzed and discussed.

Full textThis research study is concerned in the production of bio-oils from the pyrolysis of beech and pines wood representing the hard and soft wood, respectively. In order to resolve the problems related to the separation of high added value molecules from the bio-oil, a study was held out on the feasibility of the pre-separation of the chemical components of bio-oil using of a staged pyrolysis temperature in a fixed bed reactor in order to target selective thermal decomposition of macro-components of biomass (hemicellulose, cellulose and lignin). The identification of macro-component couples - marker of decomposition is made from the balance macro-component in the residual solid and identification by GC / MS of the chemical components contained in the produced bio-oil. The results of this part have shown the possibility of the pre-separation of furans and phenolic derivatives, despite of the gain in selectivity at the expense of overall yield of bio-oil. The second part of this work (concerns with the study of the production of bio-oil in fast pyrolysis conditions in a gas / solid reactor. To establish a relationship between the operating conditions and chemical composition of pyrolysis bio-oil, a tool for meaningfull comparison of experiments was developed. Experiments have shown that the yield and composition of pyrolysis oil depends mainly on the composition of wood, the heating rate and the effective residence time of the wood particles into the reactor

Full textEconomists of the 20th century paid little attention to the labour share, probably because the the labour share was thought to be constant over time and across countries. However, recent data refute this hypothesis. Hence, in recent years, economists have been increasingly concerned with the determination of factor shares. We study two aspects not explored yet : the relationship between the labour share and the distribution of personal incomes and the effect of education on the labour share. We start by putting together the existing data on country labour shares. This analysis shows that measuring the labour share is a difficult exercise and that the choice of data and adjustment affects both country ranking and movements over time within a country. We then build a general equilibrium model in which income inequality and the sharing of value-added are correlated through the equilibrium labour supply. We find an ambiguous relationship between the labour supply and the labour share which depends on the elasticity of substitution between capital and labour. On the other hand, our cross-country and panel evidence over the period 1960-1990 shows that a larger labour share is associated with lower inequality. Our next concern is the effect of education on the labour share. We study a two-sector model where workers are heterogenous with respect to their level of schooling and where firms have monopsony power due to search frictions. The more educated an agent is, the more job offers she may receive. Higher education raises wage competition among employers, and hence, wages obtained by high-educated workers, which implies that the labour share is increasing in the proportion of high-educated individuals. Lastly, we examine the role that education has played in determining the labour share using a panel of OECD countries over the period 1970-2000. Our results indicate that an increase in the proportion of high-educated workers leads to an increase in the labour share

Full textThe purpose of this work is to propose an epistemological and methodological framework for the management of the voluntary help, whatever is the size, and whatever is the level, until that of the great charitable institutions, and in a national and international context. In the first shutter, we recall the history of the voluntary help in the activities. We evoke the way of directing this type of institutions for a better control of the trades and a better adaptability of the individuals in their medium of life. That is presented in an ethical, economic and social context. In the second shutter, we propose a certain number of tools aiming at a more operational management of the organizations of voluntary help

Full textThis chapter aims at understanding the pattern of the labor share during the development process. On the one hand, the labor share is substancially higher in developed than in developing countries. On the other hand, the labor share has decreased during the past two decades in less advanced economies. Our theory emphasizes the enterplay between firm's monopsony power and the size of the informal sector when the formal labor market is frictional. The size of the informal sector parameterizes workers'outside opportunities in wage setting. In a first stage of development, productivity gains are not compensed by wage increases, as most of workers'outside opportunities depend on the informal sector whose productivity remains unchanged. The labor share decreases as a result. In a second stage of development, outside opportunities rely more on productivity in formal firms as the formal sector expands. Consequently, the labor share increases. We address the effects of FDI on the labor share in developing countries. Our theory relies on the impacts of FDI on productive heterogeneity in a frictional labor market. FDI have two opposit effects : a negative force originated by technological advance, and a positive force due to increased labor market competition between rms. We test this theory on aggregate panel data through fixed effects and system-GMM estimations. We find a U-shaped relationship between the labor share in the manufacturing sector and the ratio of FDI stock to GDP. Howeever, most countries are stuck in the decreasing part of the curve. This chapter identifies wich of the two factors, namely labour and capital, bears the cost of currency crises and for what reasons. It analyzes two main types of effects that currency crises may have on the labour share : within sector effects due to a decrease in bargaining strength of workers and across sector effects due to reallocation of factors in sector with different capital intensities. We build a descriptive model with a tradable sector and a non-tradable sector one which differ in their factor intensities and labor market is characterized by frictions that highlight the two effects. We show using data at sector level that the decrease of the labor share observed following a currency crise corresponds to a decrease within each sector. This chapter revisits the impact of wage rigidities on the labor share (LS) in the context of globalization. We use a standard HOS model with capital, labor and wage rigidity in a sub-group of countries. Globalization alters the aggregate elasticity of substitution between capital and labor through factor reallocation across sectors. We derive four main implications. First, decliningwage rigidities are more likely to increase the LS in a globalized world than in a closed economy. Second, international trade with Asian countries originates a decrease in LS in continental Europe, while keeping the US share constant. Third, globalization modifies the aggregate LS through factor reallocation, which is compatible with constant factor shares at sector or firm level. Fourth, once enriched with capital-skill complementarity, the model can predict that LS increase with development and that LS fall over time in developing countries. Those implications are broadly consistent with the empirical evidence

Full textCloud brokering is a service paradigm that provides interoperability and portability of applications across multiple Cloud providers. The attractiveness of Cloud brokering relies on the new services and extended computing facilities that enhance or complement those already offered by isolated Cloud providers. These services provide new value to Small and Medium-sized Businesses (SMBs) and large enterprises and make Cloud providers more competitive. Nowadays, at the infrastructure level, Cloud brokers act as an intermediary between the end-users and the Cloud providers. A Cloud broker provides a single point for service consumption in order to avoid vendor lock-in, increase application resilience, provide a unified billing, and simplify governance, procurement and settlement processes across multiple Cloud providers. In the future, Cloud brokers will provide advanced valueadded services and will use attractive pricing models to capture potential Cloud consumers. The aim of this thesis is to propose advanced value-added services and a pricing model for Cloud brokers

Full textThe introduction of the value-added tax in France in 1954 was a revolution in the tax field, not only for France but also for all the countries wanting to reform their tax system. In fact, the value-added tax occupies currently an important place in the world tax system due to, among other reasons, its high budgetary return and its economic efficiency. In Syria, in response to budgetary needs provoked by, on one hand the oil resources decline, and on the other hand the decrease in customs revenue, it is intended to introduce a value-added tax with the aim to fill the budgetary deficit thus caused. Being both a modern and a sophisticated tax, the implementation of the value-added tax in the Syrian tax system will not be without difficulties. In fact, how to introduce such a tax while the administrative, economic and psychological structures are not yet ready to receive it ? Furthermore, once the tax is implemented, what will be its budgetary, administrative, economic and social impacts ? These are the questions which we try to answer in this thesis, based on a comparison of the indirect taxations in France and Syria

Full textIn this thesis, we study two paradigms that aim to improve the best-effort service provided by the TCP/IP protocols of the Internet network. The thesis is organized in two parts. In the first part, we study differentiated services mechanisms. In particular, we develop models to evaluate the performance of TCP protocol in networks with multiple levels of assurance. We also use the model to investigate the problem of setting the parameters of routers with two drop probability functions. In the second part, we study overlay multicast, a new approach to improve the quality perceived by multicast applications. This approach requires the design of specific algorithms to optimize end-to-end delays and bandwidths. We propose and evaluate analytically and by simulation algorithms for overlay construction adapted to this kind of applications

Full textThe purpose of this research is to capture and analyze the relationships between architecture and recent technologies in terms of perception. Far from the supposed subjectivity, this analysis guided by the notion of perceptual experience, is based on both phenomenological and aesthetic concepts. This double reflexivity also relates to the conceptual and "concrete" case studies operating the architectural vision of spatiality in speculative tensions between the "digital" and the physical word. The problematic concerns the reception of architecture as a cultural value and intellectual production, coordinated by technological means that amplify it. In keeping with the assumption that today's architecture is far away to "serve" only as a response to formal, structural and functional questions, this research shows that architecture is increasingly approaching the artistic field in phase of permanent experimentations. By analyzing the factors of aestheticization of various concepts, case study seeks to understand the cognitive and the aesthetic value of the technological reception — new notion, introduced as an operational concept to approach the sensitive, hybrid and variables issues of architectural production. The originality of this research consist of analyzing the unstable connections that characterize the current processes of various transitions in the field of architecture. As such, this research proposes to open the scope of the discussion around the "digital" according to the principles of architectural singularity in the plurality of possible receptions

Internal audit detects problems; identify their causes, and makes recommendations to solve them. In Morocco, several pieces of legislation have planned the establishment of the internal audit within the Moroccan organizations. However, despite this, the internal audit does not play effectively its role: why and how?

Full textRecently customer-based product development is becoming a popular paradigm. Customer needsand expectations are identified and transformed into requirements in systematic processes for productdesign with the help of various methods and tools. However, in many cases, these approaches fail tofocus on the perceived value that is crucially important when customers make the decision ofpurchasing a product. The requirements specification derived from these approaches are typicallyvalue-implicit.In this thesis, a prescriptive approach to derive value-based requirements specification is proposedby integrating the concept of value into the house of quality of quality function deployment. Anintegrated set of theories, methods and concepts is introduced in order to mitigate the sevenmethodological problems of house of quality regarding to establishing appropriate value-basedrequirements specification. The foundations of the approach include concepts of objective, valuemodel and consequence model, methods of means-ends objectives network, fundamental objectiveshierarchy, response surface methodology and value-driven design, and theory of multi-attribute utilitytheory. The procedure of the approach is a four-step process: (1) identify and structure objectives frominitial customer statements of expectations, (2) specify attributes and construct customer value model,(3) transform fundamental objectives into engineering characteristics to construct system value model,and (4) derive component value models from system value model. Through this procedure, initialcustomer statements can be reasonably derived into customer value model, system value model andcomponent value model. The benefits of the approach are that it enables (1) reasonably qualifying andquantifying customer value, and performing value modeling and simulation, (2) perceived customervalue being subsequently used reactively for design evaluation, and proactively for value-drivendesign.The approach is applied in the context of a European Community’s R&D project CRESCENDO tohelp constructing airlines’ group value model for commercial aircraft development. This applicationfocuses on the first two-steps of the approach, and the value models are implemented in businesssoftware Vanguard Studio

Full textThe V. A. T. Is traditionally presented as an economically neutral tax because of a field of application intended to be general and because of the mecanism of the right of deduction of the previously paid tax. However, in certain cases, the enterprise finds itself in the position of the final consumer: certain economic activities are not submitted to v. A. T. , certain goods and services are excluded from the right of deduction and there is time allowed before the tax is recovered and repaid. The V. A. T. Becomes remanent in the accountancy; it becomes remanent economically if the enterprise is not able to passit into the sale price. The economic and financial analysis shows that French enterprises bear more than 16% V. A. T. Net and that remanences are comparatively concentrated (health, housing, agriculture, banks, insurance). Moreover, the analysis on the E. E. C. Level shows that in spite of a will to bring things into line, the remanences are not the same in every country. Yet, the level of remanences affects the conditions of competition among the E. E. C. Countries only in a residual way. (. . . )

Full textStandardization activities are dedicated to the elaboration of rules which are used to prescribe practices through obligations of results (product characteristics) or obligations of means (production processes characteristics). These rules can be elaborated by firms or by industry associations. Our study contributes to answer two economic questions of the oil upstream industry. The first one is the measurement of the added value of the use of industry standards in the elaboration of the firm references documents collections (its technical specifications). The second one is related to the different types of standardizations and the idea that industry standardization is a tool to organize concurrency of the market in the oil industry.Firstly, the use of standards is essential to produce efficiently, safely (without accident) for many years and often essential in order to access natural resources. Secondly the identification of the main sources of standardization benefits, in addition to the conventionalist analyze of quality and of the “mondes de production” help us to identify four productive interfaces for which a mix of standardization (with internal and external standardization) is more adapted. Finally the prevention of risks, and more globally the quality management, is positively impacted by industrial standardization.Nevertheless, the gains observed in our case study cannot be transposed to other case studies because, as the institutionalism theory and the conventionalism theory explain, the interrogation about the benefits of standardization cannot be completely resolved because of the diversity of the type of standards in one side, and the diversity of production situations in the other side

Full textThis work aims to identify the similarities and/or discrepancies between Anglo-Saxon and European multinationals. The descriptive studies postulating the convergence of the stakeholder model toward the shareholder value model are put to question. Three econometric studies were conducted in order to investigate this possible convergence. The main conclusion that emerges is that of the convergence toward a hybrid governance system. The duality of the shareholder model (corporate capital structure, R&D expenses, payout ratios) supports this conclusion, and hence opens the way to new studies of the discrepancies inside the shareholder model. Two other conclusions are also worth mentioning: the negative correlation between corporate leverage and shareholder value, and the vertical integration rationale in intra-EU(15) foreign direct investments

Full textThe simulation methodology described by King (1983 a,b) is used to evaluate the welfare effects of six vat reforms. Starting from the 10645 households of the INSEE survey budgets des familles 1979, we obtain a sample of 1045 grouped households, and estimate a linear expenditure system with 23 goods categories. The results are very close to those obtained in previous studies (Baccouche (1984), Baccouche and Laisney (1986)), in spite of large differences in the methodology (estimation on individual or grouped cross section data or even on aggregate time series data) and both in the nature of goods considered (inclusion or exclusion of durables) and in the level of aggregation (4, 11 and 23 goods). A result common to all reforms is that the effects on inequality measures remain small, even for quite dramatic reforms, which points to the limits of the redistributive effects of vat reforms. The analysis provides approximations for the standard errors of the welfare measures we calculate. Taking account of these proves important as the significance of results varies substantially with the definition of reforms

Full textThis thesis would explain how the concept of cash-flow net will be used in stock valuation and in the computation of the economic value added. It is divided into two parts : the first part treats the traditional concepts of value creation. It demonstrates the importance of the information content in dividend policy as a mean of communication between the entreprise and the market. It suggests the importance of this tradeoff between risk and return in value cration. The second part introduces a theory of stock valuation based on cash-flow analysis to price stocks, where the cash receipts and the cash payments of the firm is projected for each time period for ever where a continuous adjustment of the variables affecting the discounted present value of the cash-flow stream will show its effect on the value of the company's stock. Not only does this starting point by-pass certain measurement problems, but it also direct attention to the relevant variables in a manner that other approaches may not. The financial manager is now required to generate a chas-flow net not only ti satisfay the explicit cost but also the implicit cost of the providers of funds in order to create value. And to determine the optimal cash balance that minimizes opportunity cost and maximizes shareholder's wealth

Full textThis thesis aims at defining and integrating the' human capital' notion within the framework of General Accounting. This very old problem had not received up to now any acceptable solution. Here the problem is reconsidered according to the proposed model by Trémolières, where it is assessed that ‘Human Capital' doesn't have to be integrated in the firm assets as imagined or defended by several other researchers. Here the employees keep their juridical independence with respect to the firm identity, and only the ‘added value' that they give to the firm must be accounted for. By ‘added value' it is assumed here that this is relative to any supplementary effort, not written by contract, that brings more value to the firm. It is really there that can be found a reason to speak of ‘accounting human capital' , the term ‘capital' being taken in the accounting meaning of ‘virtual shareholders', that is people having contributed, ‘not by contract', to an increased value of the considered firm. In some sense it is nothing else that the moral debts that the classical shareholders owes to other contributors to the value of the firm. The new shareholders are called ‘virtual' because they don't have, a priori, any right to benefit from the dividends that can be distributed. Nevertheless, the idea of associating them to the set of people having contributed to a better value of the firm is important to morally thank these people for their ‘free' implication in the sense of the' liberalitarism' notion by Aristotle. This can be registered as virtual debts, or specific ‘human reserves', or even ‘virtual shareholders' or ‘virtual equities' that can be recognized in case of increase in capital. The interest of this relies on the fact that the ‘free' initiatives' having succeeded can be memorized by the firm in the accounting equities capital This idea can lead to more honesty and justice with respect to the firm's employees but also to a better management. This theory of Human Value Added to an ‘average behavior' is validated by an important inquiry aiming to know how these new ideas can be accepted in modern management

Since the establishment of VAT, as a major instrument to fund the State’s budget, it is the time to take a critical look on the VAT system. The right to deduct VAT is fundamental composant of VAT system and of its neutrality. The value added tax has a significant impact on each citizen of the European Union and we must give ourselves the means to improve the application of the deduction mechanism and develop the additional methods to fight against fraud

The effects of operating conditions on the extraction yield of each target compound and the antioxidant activity of the extracts were determined. To understand the entire process, the project aims to investigate the impact of concentration and drying processes using vacuum evaporation and lyophilisation.

Full textThe first part of this PhD thesis presents a detailed methodological study for the ring-closing-metathesis (RCM) reaction of fluorinated olefins, in homogeneous medium, involving dienes bearing central amide or oxaza bonds. The key parameters of this reaction have been studied and various substitution strategies, on both terminal olefin positions, have been developed, allowing reaching the best conversion rates ever obtained in terms of fluorinated olefin metathesis. The second part of this book describes the access to (E) fluoropseudopeptides, from -lactams having a fluoroolefin, previously synthesized through ring closing metathesis. A general method for the preparation of a range of Xaa-[(E)CF=CH]-Gly fluoropseudopeptides is presented. The third part of this manuscript is dedicated to a piece of work toward the development of the RCM reaction of fluorinated olefins through supported catalysis, using Bio-Ru-SILP materials. These materials consist of an ionic liquid phase, immobilized on a biodegradable alginate support, wherein a ruthenium catalyst has been dissolved.

Full textThe production of value-added products such as engineered wood products is growing. The specifications on the final moisture content of these products are much more stringent than for lumber. The wood must be dried at lower final moisture content and also with a lower moisture tolerance. The traditional means to dry these products is to use the technique of equalizing at the end of the drying cycle. This technique, although very powerful, has the effect of extending significantly the total drying time and can be complex to implement industrially. The aim of the work was to explore the technical feasibility of a combined approach method (conventional and continuous high frequency) for drying black spruce lumber for the manufacture of engineered wood. Conventional drying approaches with and without equalizing, served as control. Drying time, distribution of final moisture content, proportion of pieces in a given moisture content tolerance (between 11 and 15%) and warpage were characterized. Two studies were carried out from two wood supplies at different initial moisture contents. The combined approach has allowed a considerable reduction in drying time and repeatability of results specific to the final moisture content without more warping than control approaches.

Full textIn French restaurants, coffee is one of the last products sold without any information or choice: as a basic commodity, undifferentiated, and with an unpredictable and variable quality. Therefore, consumers do not grant much value to this product. In parallel, the coffee offer for consumption at home is improving in terms of quality and choice. Many innovations are available on the supermarket's shelves in the category of pre-dosed pods, for the preparation of coffee by the cup. The purpose of this thesis is to help the development and supply of a coffee offer in restaurants, with high-added value for consumers. In this aim, the Part 1 makes a diagnosis of the current supply and demand of coffee in French restaurants. Interviews with consumers reveal a demand linked to social functions of coffee, and a fear to be disappointed by its taste. The sector analysis, based on market data and field observations, shows that the supply of coffee by roasting companies relies on services offered to restaurant managers. This analysis enables to better understand mechanisms of the coffee-commodity industry, and to formulate hypothesis of development of an offer with higher added-value by a vertical differentiation (by the quality) or by a horizontal differentiation (by the variety). In Part 2, these hypotheses are tested in order to evaluate their relevance regarding consumers, through methodologies coming from sensory evaluation, and experimental or behavioral economics. Finally, feasibility of these two types of differentiation is discussed based on interviews with restaurant managers. An offer with high-added value for consumers, relevant and feasible, could arise from a development of the activities in the sector, in order to get stakeholders together around a strategy of making the offer unique

Full textThe cooperation, and through it the creation and distribution of added value in inter-organizational cooperation systems, is a response increasingly used by companies and organizations as a new conception of their economic space. In this context, this new form of "productive order" is a real Trojan horse to capture, create and distribute new resources and maintain competitive advantages. Our research work focuses on the situations of inter-organizational cooperation (SCIO) and more particularly on the creation and distribution of added value (CRVA), in a sense dedicated to piloting.This thesis is based on three socio-economic research-intervention case studies (a longitudinal case and two complementary cases), enriched by in-depth interviews with their leaders. It studies the management of CRVA-SCIO, in order to understand the logics of construction and organization of cooperation situations, explains the measurement and evaluation of individual and collective performance and proposes an operational management model, connected to all interfaces , working with an open-ended approach and proposing innovative tools and indicators to make cooperation effective and sustainable. The challenge of our research is first and foremost at the academic level to give a contribution to the theoretical evolution of management control of inter-organizational systems. Then, at the managerial level, to make a contribution to the leaders and managers in order to renovate and develop their system of management of inter-organizational configurations

Full textPopulation growth, coupled with a general increase in standard of living, result in a booming demand for raw material and energy. To face this challenge, an increased attention is paid to the use of renewable energies and natural resources. Among them, biomass is especially promising. Its advantages (abundance, distribution all over the Earth) are balanced by several drawbacks (low energy density, high moisture content,…). To overcome these problems, torrefaction is the most traditional way, but it has some inconveniences (increased ash content, loss of material). Hydrothermal carbonisation (HTC) is a possible alternative. The purpose of this thesis is the study of HTC a means to beneficiate the lignocellulosic biomass. Three main aims were identified: increase of the energy density, recover molecules and minerals of interest. The study initially focused on HTC of molecular model systems present in wood. Beech wood was also studied, as a model biomass. This study allowed determining optimal experimental conditions for treatment of further biomasses. Finally, other activation methods have been tested, such as microwaves, and supercritical fluids. Hydrochars obtained after HTC feature a concomitant decrease of the atomic H/C and O/C ratios. Liquid phase contains different molecules of interest (furfural,…). Finally, ash content decreases after HTC owing to a partial leaching of some elements (alkali and alkaline earth metals). In conclusion, HTC seems to be an interesting alternative to torrefaction as it allows for the production of hydrochars suitable for gasification, and the recovery of molecules and minerals of interest. The interest and technical feasibility have been demonstrated in particular for biomasses with high moisture (agricultural crops) or with high pollutant contents (grounds of waste disposal)

Full textFlip chip technology is increasingly prevalent in electronics assembly [threedimensional (3D) system in package] and is mainly used at fine pitch for manufacture of megapixel large focal-plane detector arrays. To estimate the reliability of these assemblies, numerical simulations based on finite-element methods appear to be the cheapest approach. However, very large assemblies contain more than one million solder bumps, and the optimization process of such structures through numerical simulations turns out to be a very time-consuming task. In many applications, the interconnection layer of such flip-chip assemblies consists of solder bumps embedded in epoxy filler. For such configurations, we propose an alternative approach, which consists in replacing this heterogeneous interconnection layer by a homogeneous equivalent material (HEM). A micromechanical model for the estimation of its equivalent thermoelastic properties has been developed. The constitutive law of the HEM obtained was then implemented in finite-element software (Abaqus®). Elastic properties of materials that compose the assembly were found in literature and by using mechanical characterization method especially nano-indentation. Thermomechanical responses of tested assemblies submitted to loads corresponding to manufacturing conditions have been analyzed. The homogenization-localization process allowed estimation of the mean values of stresses and strains in each phase of the interconnection layer. To access more precisely to the stress and strain fields in these phases, two models of structural zoom (model coupling and submodeling), taking into account the real solder bump geometry, have been tested. The local stress and strain fields obtained corroborate the experimentally damage initiation of the solder bumps observed
