Amzil, Aimad. « Place des ERP dans le suivi de la performance des filiales par la maison-mère ». Thesis, Besançon, 2016. http://www.theses.fr/2016BESA0005/document.
Texte intégralThis study seeks to shed the light on the role of Enterprise Resource Planning (ERP) as a management tool adopted by multinational corporations in their monitoring of the headquarters/ subsidiary performance. We have opted for a deductive approach, focusing on multinational corporations whose subsidiaries are based in Morocco and which are endowed with the ERP tool. To meet this end, we have carried out both a qualitative and a quantitative study. Qualitatively, the six semi directive interviews conducted with the subsidiaries management fit in harmoniously with the items that figure in our questionnaire, submitted to 104 subsidiaries in the framework of a quantitative study. We have found out that even if subsidiaries benefit from autonomy as far as management is concerned, the headquarters still impose the strategic vision and intervene at how ERP must be implemented. Indeed, ERP acts positively on the headquarters/subsidiary relationship by rendering data even, making coordination fluid and facilitating budget control and goals follow- up. Other merits that the ERP tool offers include: time saving, ease of use, tracking, availability and easy data exchange. Nevertheless, ERP has not been fully utilized due to the difficulty of matching its features. Basically, head offices make use of ERP in evaluating financial performance, namely reporting sales and inventory management. Otherwise, it remains less operational

Texte intégralFor on half-century, and all over the word companies have adhered more and more to the methods and practice of " Quality ". The latter can however be summarized in terms of aptitude to satisfy the user's need, definition official of AFNOR (French Association of Standardisation). According to the testimony of the specialists and certain sociologists, the translations of the vocabulary of “Quality” caused in France errors and incomprehension. This is the consequence of the importation of the Japanese and American, known practice like “Total Quality”. We carried out a descriptive reading about the directions of the vocabulary symposium with the word “Quality” between 1950 and 2000. Work on great corpus. We are based on the theoretical and methodological principles discourse analysis. This relatively recent discipline within sciences of the language is located at the crossroads of other disciplines. Considering the great proliferation of the literature about “Quality”, our analysis can not be exhaustive

Texte intégralThe sector of the building constitutes an important target in the sustainability. Faced with growing environmental pressure, the methods of green building assessment were created. The initiative HQE® is one of the approaches proposed in France. In spite of the fact that this initiative is very recent, some weaknesses and strengths are already associated with it. Naturally, the fact of giving the concrete contents to the 14 targets is very useful. However, from the mathematical point of view, considering the uncertainties of parameters is also important. The inaccuracy and the subjectivity cannot be ignored over the long term because the whole projects are subjected to at least a certain degree of uncertainty. The French method to assess green buildings “NF bâtiments tertiaires- démarche HQE®” constitutes the framework of our research. The challenge was to improve the credibility of the evaluation. We thus had to above all identify and formalize the uncertainties linked to this evaluation. The possibility theory then allowed proposing various tools according to the nature and to the number of parameters. With the help of these tools, we were able to associate one degree of the truth to the evaluation of every sub-target. This degree allows the actors concerned to make decisions without ignoring the inaccuracies of the parameters or the uncertainties on the knowledge concerning the building. It can also incite them to improve the quality of the data when the degree of the truth is too weak. The proposed method was used for the data of a certified construction “NF bâtiments tertiaires- démarche HQE®”: the professional secondary school of Blanquefort

Texte intégralThe aim of the study is to develop a model, which helps to assess the improvement of the environmental quality of buildings by the integration of solar components. The method was developed according to three steps : prediction of the productivity of building integrated solar components. The models of the three basic solar systems are presented ; prediction of the energy consumption in the building. The thermal model of the building, and the coupling between the building and the solar component is explained; environmental indicators assessment by life cycle analysis. Life cycle inventory databases of photovoltaic systems and solar water systems are collected, and these inventories are then integrated in the life cycle analysis database of the building. The whole package has been applied on several case studies, and a life cycle analysis was performed on each case

Texte intégralL’objectif de notre thèse est de contribuer à une meilleure connaissance des déterminants d’une césarienne de qualité et de montrer comment en situation réelle (cas d’un district urbain au Burkina Faso) on peut agir sur ces déterminants pour améliorer la qualité des césariennes.
Dans le cadre d’un projet multidisciplinaire (santé publique, mobilisation politique et sociale, anthropologie) d’Amélioration de la QUalité et de l’Accès aux Soins Obstétricaux d’Urgence - le projet AQUASOU (2003-2006) - nous avons pu mettre en œuvre des activités visant à améliorer l’accès à une césarienne de qualité dans le district du Secteur 30) à Ouagadougou, Burkina Faso. Nous avons mené une étude Avant-Après et utilisé des méthodes d’évaluation mixtes quantitatives et qualitatives pour comprendre dans quelle mesure et comment ce type d’approche globale améliore la qualité de la césarienne. Nous avons utilisé le cadre d’analyse de Dujardin et Delvaux (1998) qui présente les différents déterminants de la césarienne pour organiser et structurer nos résultats. Cette expérience s’étant déroulée dans le cadre d’un projet pilote nous avons également évalué le degré de pérennité du projet AQUASOU quatre ans après sa clôture officielle et analysé sa diffusion au niveau région et national.
Le cadre d’analyse de la césarienne de qualité avec ses quatre piliers (Accès, Diagnostic, Procédure, Soins postopératoires) a permis d’aller au-delà de la simple évaluation de la qualité technique de l’acte césarienne. Il a structuré l’analyse des différentes barrières à l’accès à la césarienne comme par exemple l’acceptabilité des services par la population et le coût de la prise en charge.
L’analyse des discours des femmes césarisées a mis en lumière le sentiment de culpabilité des femmes d’avoir eu une césarienne - ne pas avoir été « une bonne mère » capable d’accoucher normalement. Les questionnements sur la récurrence de la césarienne pour les prochaines grossesses, les dépenses élevées à la charge du ménage, la fatigue physique et les complications médicales possibles après l’opération mettent la femme dans une situation de vulnérabilités plurielles au sein de son couple et de sa famille.
L’évaluation du système de partage des coûts pour les urgences obstétricales mis en place en 2005 dans le district du Secteur 30 a montré qu’il était possible de mobiliser les collectivités locales de la ville et des communes rurales pour la santé des femmes. La levée des barrières financières a pu bénéficier à la fois aux femmes du milieu urbain et rural mais l’écart d’utilisation des services entre le milieu de résidence n’a pas été comblé et cela confirme l’importance des barrières géographiques (distance, route impraticable pendant la saison des pluies, manque de moyen de transport) et socioculturelles.
L’étude sur le rôle des audits cliniques ou revues de cas dans l’amélioration de la qualité des soins a montré que les soignants avaient une bonne connaissance du but de l'audit et qu’ils classaient l'audit comme le premier facteur de changement dans leur pratique, comparé aux staffs matinaux, aux formations et aux guides cliniques. Cependant, l’institutionnalisation des audits se révèle difficile dans un contexte de manque de ressources qui affecte les conditions de travail et dans un environnement peu favorable à la remise en question de sa pratique professionnelle.
L’évaluation de la pérennité du projet pilote quatre ans après la fin du soutien financier et technique montre que les bénéfices pour la population sont toujours là en terme d’accessibilité à la césarienne :coûts directs pour les ménages de 5000 FCFA (US $ 9.8), qualité des soins maintenue avec une diminution de la mortalité périnatale précoce pour les accouchements par césarienne de 3,6% en 2004 à 1,8% en 2008.

Texte intégralAs a technical standard, traceability in food and health field has been appropriate by private and institutional actors imparting it, thus, a legal meaning. This progressive way from a normative system to another has been connected to the food and health crisis context in which standardization has shown its limits. On the same way, the legal aspect of traceability has connection with the precautionary principle and presents some issues in a field linked to the risk factor and to the transformation of safety expectations in and by the law. The latter has become a privileged way of risks management, which cannot be limited to a domestic scope ; European and international areas are also concerned due to the fact that traceability - and the question of food and health safety – are interlinked with the free movement of goods. Despite the interest of the new legal norm in the risks management scope, its appropriation by the judge shows that the law has difficulties to take up a technical standard. This institutional actor is referring to this new concept with moderation though the litigation complexity of risks and the increasing technicality of law encouraged a whole appropriation. Therefore, traceability benefits from an imperfect increasing legal meaning in food and health field
Huang, Fan. « Allocation des ressources fondée sur la qualité du canal pour la voie descendante des systèmes LTE ». Thesis, Université Paris-Saclay (ComUE), 2015. http://www.theses.fr/2015SACLS250/document.
Texte intégralThis research takes place in the context of Private Mobile Radio networks evolution which aims at designing a new LTE based PMR technology dedicated to public security services. As the frequency bands dedicated to this service is scarce and the need of public safety forces is different, we have revisited the Resource Allocation problem in this thesis with two main objectives: designing new allocation algorithms which outperform the spectrum efficiency and serving fairly the users instead of maximizing the global network throughput.This thesis proposes new Resource Block (RB) allocation strategies in LTE downlink systems. Instead of the well-known resource allocation algorithms, which work on the condition that the RB capacity is already estimated, our RB allocation schemes can improve the potential of the channel capacity, using Beamforming cooperation and game-theoretical problems1. With the MIMO (Multiple-Input-Multiple-output) antennas, the Beamforming technique improves the received signal in order to increase the SINR (Signal-to-Interference-plus-Noise-Ratio), but the improved signal may also influence the inter-cell interference in the neighbouring cells. As inter-cell interference is the main interference in the OFDMA system, a smart scheduling can choose UEs (User Equipment) in adjacent cells to control interference increment caused by Beamforming.In traditional methods, the scheduler allocates RBs to UEs depending on the RB capacities and other parameters, the system then applies the Beamforming technique to these chosen UEs. After the Beamforming, the RB capacity varies but the scheduler keeps the same allocation.Our scheme allocates the RBs and chooses Beamforming vectors at the same time to enhance the performance of the Beamforming technique. It increases the average throughput by increasing the RB’s average capacity. Because more parameters are taken into account, the complexity also increases exponentially. In the thesis we find an iterative method to reduce the complexity. From the simulations, our iterative method also has good performance and improves more than 10% of throughput on the cell edge.2. In contrast to the performance first algorithms, game theoretic allocation schemes maximize the UEs’ utility function from the economical point of view. The NBS (Nash Bargaining Solution) offers a Pareto optimal solution for the utility function.The traditional NBS allocation in an OFDMA system is to optimize the subcarrier allocation at each time slot, but in the OFDMA system, the subcarriers are composed of Resource Blocks (RB) in time series. We propose an RB NBS approach, which is more efficient than the existing subcarrier NBS allocation scheme.We analyze the fast-fading channels and compare them without the path-loss influence. Because of the great path-loss in cell edge, the edge UE always has lower RB capacity than the cell center UE. Our idea is to bring in a compensating factor to overcome this path-loss influence, and the compensating factors are carefully chosen to maximize the NBS function. However, the computation of these factors has a high complexity and we develop four approximated solutions which give same performance and accuracy. The performance evaluation confirms that our method and its approximated solutions are able to spread resources fairly over the entire cell

Texte intégralThe need for competitiveness requires today to design faster, better and cheaper than competitors. In this context, taking into account the product constraints depends on the return of performance indicators (cost, risk, quality, time. . . ). Therefore, it is important to evaluate in detail these indicators ta return robust and coherent information. This information allows making a good decision to pilot the product development cycle in order to obtain a better quality/cost ratio. The interoperability of the approaches QFD, FMEA and KCs was studied to exploit them in a single framework of quality management ta ensure homogeneity and coherence of the quality indicators. Cast was taken into account in proposing the CbFMEA approach based on classical FMEA, which estimates the cost of non-quality to assess the failure financial severity of the product. This cost was added to the manufacturing cost of the product estimated by the ABC method. The cost approach (CbFMENABC) was coupled with the quality approach (QFD / FMEA / KCs) resulting a combined quality/cost approach illustrated by an activity diagram. An information model of the joint quality/cost approach was proposed and a prototype has been developed to validate the proposed concepts and model. An application of this approach was illustrated in conceptual process planning phase via a case study. This application is narned QCCPP; it provides indicators of capability, risks and cost. The objective is to support the decision-making during the multi-criteria selection of manufacturing alternatives for the joint improvement of product quality/cost ratio

Texte intégralThe screen is a ubiquitous interface daily used. Overextended by screens, the individual cannot perceive all the information. Understanding the visual attention to media content is a crucial issue in the marketing strategy. A parameter of the mediated image has not been taken into account in the studies conducted so far: the technical quality of the image. It can be defined as the set of parameters that objectively compose an image: the definition, the image frequency, the brightness dynamics and the color. To measure the perception of the improvement of these parameters, an exploratory phase was conducted including a perceived quality test, a focus group and interviews. A confirmatory empirical phase followed to study the visual attention and memorization of mediated information through two experiments. A series of interviews and a focus group explored hyperreality in the mediated image and its impact on immersion and quality of experience

Texte intégralTraditionally, when it comes to generating high-resolution (HR) images from a low-resolution(LR) images, the methods proposed so far have mainly focused on super-resolution techniques that aim at recovering the most probable image from low-quality image. Doing so ignores the fact that there are usually many valid versions of HR images that match a given LR image. The objective of this work is to obtain different versions of HR images from the same LR imageusing a generative adversarial model. We approach this problem from two different angles. First, we use super-resolution methods, where in addition to the LR image, the generator can be parameterized by a latent variable to produce different potential variations of the image. Such a conditioning allows to modulate the generator between retrieving the closest image to the ground truth and a variety of possible images. The results demonstrate our superiority in terms of reconstruction and variety of plausible hallucinated images compared to other state-of-the-art methods. The second approach builds on the work of image-to-image translation, by proposing a new approach where the model is conditioned on a LR version of the target. More precisely, our approach aims at transferring the fine details of an HR source image to fit the general structure, according to the LR version of it. We therefore generate HR images that share the distinctive features of the HR image and match the LR image of the target duringdownscaling. This method differs from previous methods that focus instead on translatinga given image style into target content. Qualitative and quantitative results demonstrate improvements in visual quality, diversity, and coverage over state-of-the-art methods such asStargan-v2.

Texte intégralShellfish production is a leading economic activity on French coast. Hatcheries et nurseries which produce oyster spat to be sold to producers, offer an alternative way of breeding under controlled conditions with the possibility to monitor quality of in et out waters. Within those structures, water treatment is essential for adult oysters, larvae breedings et microalgae production. The aim of this work is to develop ultrafiltration for water treatment in those shellfish production facilities. The objectives are to remove pathogens et parasites from upstream water in order to protect animals et cultures et to treat effluents with the aim to inactivate non endemic biological material from concerned production area. Reliability et sustainability of ultrafiltration were checked at semi-industrial scale et validated for the matrices tested by an optimisation of operating conditions, cleanings et the use of air-backwashes. A biosecuring of breedings was obtained with (i) the protection of oysters from larvae stage to adults towards pathogenic agents (virus OsHV-1 et bacteria Vibrio aestuarianus) (ii) the retention of oyster gametes in effluents, potentially detrimental for marine biodiversity, (iii) the reuse of effluent within shellfish farms. Microalgae production was also improved with ultrafiltration suggesting the possibility of a technology transfer to industry

Texte intégralQuality of service is a huge issue for telecommunications operators since they have to master and evaluate it in order to satisfy their customers. To replace expensive and time-consuming human judgment methods, objective methods, integrating objective models providing a prediction of the perceived quality, have been conceived. Our research aimed at developing a technical diagnostic method, complementary to objective voice quality models, which provides specific information about the nature of the perceived voice quality impairments and identifies the underlying technical causes. Assuming that speech quality is a multidimensional phenomenon, our technical diagnostic method is built on the modelling of the four perceptual dimensions identified in the literature: “Noisiness” relative to the perceived background noise, “Continuity” linked to discontinuity, “Coloration” related to frequency–response degradations and “Loudness” corresponding to the impact of the speech level, each one being quantified by quality degradation indicators based on audio signal analysis. A crucial step of our research was to find and/or to develop relevant quality degradation indicators to perfectly characterize each dimension. To do so, we identified quality degradation indicators in the most recent objective voice quality models (particularly the ITU-T P.863 recommendation, known as POLQA) and we analysed the performance of identified indicators. Then, the most relevant indicators have been considered in our diagnostic method. Finally, for each dimension, we proposed a detection block which automatically classifies a perceived degradation according to the nature of the defect detected in the audio signal, and an additional block providing information about the impact of degradations on speech quality. The proposed technical diagnostic method is designed to cover three bandwidths (Narrowband, Wideband and Super Wideband) used in telecommunications systems with a priority investigation to Super Wideband speech signals which remain very useful for future telephony applications

Texte intégralCyber attacks cause considerable losses not only for end-users but also service providers. They are fostered by myriad of infected resources and mostly rely on network resources for whether propagating, controlling or damaging. There is an essential need to address these numerous attacks by efficient defence strategies. Researchers have dedicated large resources without reaching a comprehensive method to protect from network attacks. Defence strategies involve first a detection process, completed by mitigation actions. Research on detection is more active than on mitigation. Yet, it is crucial to close the security loop with efficient technique to mitigate counter attacks and their effects. In this thesis, we propose a novel technique to react to attacks that misuse network resources, e.g., DDoS, Botnet, worm spreading, etc. Our technique is built upon network traffic management techniques. We use the Multiprotocol Label Switching (MPLS) technology to manage the traffic diagnosed to be part of a network misuse by detection processes. The goals of our technique can be summarized as follows: first to provide the means — via QoS and routing schemes — to segregate the suspicious flows from the legitimate traffic; and second, to take control over suspicious flows. We profit from the enhancement on the inter-domain MPLS to permit a cooperation among providers building a large-scale defence mechanism. We develop a system to complete the management aspects of the proposed technique. This system performs tasks such as alert data extraction, strategy adaptation and equipments configurations. We model the system using a clustering method and a policy language in order to consistently and automatically manage the mitigation context and environment in which the proposed technique is running. Finally, we show the applicability of the technique and the system through simulation. We evaluate and analyse the QoS and financial impacts inside MPLS networks. The application of the technique demonstrates its effectiveness and reliability in not only alleviating attacks but also providing financial benefits for the different players in the mitigation chain, i.e., service providers

Texte intégralIndustrial products currently developed are more and more complex and make use of several technologies at the same time. Moreover, design times are increasingly reduced, bringing new constraints during pre-industrialization phases. Companies have to rapid solve many problems by involving experts who have a partial knowledge of the product limited to their field of specialty. These new constraints are rarely taken into account in traditional problem solving methods. The purpose of the research work developed in this PhD thesis is quality problem solving methodology for new high technology products. By "quality problem", we mean any technical problem due to a special cause concerning the product or the process. The aim of the study is thus to propose a methodological structure adapted to this context from an organizational, sociocultural and technical point of view. The structure must be adaptable to the future evolution of this type of company: cohabitation of stabilized products and newly developed products. The objective is not to propose yet another problem solving method but rather a tunable structure in accordance with each configuration. The suggested principle is founded on a basic structure (phases and tools) modified by two assessments: the assessment of the problem profile and the assessment of its methodological state. The crossing of these two evaluations allows us to build a contextualized problem solving method with the phases that remain to be created and dedicated instrumentation for each phase. We worked on three main axes to develop this instrumentation : -selection of the methods and tools that are the most adapted to our context, improvement of these entities, analysis of the potential positive interactions between them -development of new tools -analysis of methodologies for other fields (criminology and accidentology) which have similar constraints to the studied context and their adaptation to industry. This PhD bas been carried out in the frame of a "CIFRE convention" with TRIXELL committed to the development and production of a complete family of X-ray flat panel digital detectors for the entire radiological imaging industry

Texte intégralThe design methodology "frist design" for mechanical systems is presented. It is based on a hierarchical organization of the design taken into account the notion of robustness at an early phase of the design. The aim is to improve the quality of the system in order that il became robust, less sensitive to the variability of the exterior parameters and the design parameters. The performances and the design variables are introduced all along the design cycle. As an example, the methodology will be applied to the optimization of a vehicle suspension system design parameters. First of all the functional parameters will be optimized in order to improve the vehicle road behavior. These parameters will be then used as target for the material parameters optimization which define the detailed characterics of each part ensuring an optimal behavior whatever the external conditions

Texte intégralIn eukaryotes, the genetic information is transcribed into messenger RNA which undergoes various processing and assembly events prior to its export from the nucleus. These transcript modifications are performed by numerous protein factors recruited to the nascent transcript, thus making a messenger ribonucleoprotein particle (mRNP). mRNP biogenesis is tightly interconnected with both transcription and quality control to ensure efficiency and accuracy in production of mature mRNPs. Recent findings suggest that members of THO-Sub2 complex might be crucial factors in coupling transcription, mRNP biogenesis and export. In our group, we have implemented an innovative assay to study mRNP biogenesis and quality control, based on the expression of the bacterial factor Rho in Saccharomyces cerevisiae. Rho interferes with proper mRNP assembly and generates aberrant transcripts degraded by the nuclear degradation machinery. In this study, we use Rho experimental system to expand our findings on Rrp6 and exosome involvement in quality control degradation of transcripts, as well as to better characterize the role and function of THO-Sub2 complex in the process of mRNP biogenesis. Obtained results reveal an interesting difference in behavior of THO complex members upon Rho action and disclose their dependence on binding to the RNA, which could not be observed by other experimental techniques. This substantiates the expected potential of Rho-based experimental system in the study of protein factors involved in mRNP biogenesis and quality control

Texte intégralIn recent years, the telecommunications industry observes a tremendous increasing of broadband access penetration level. Indeed, the number of subscribers with access to broadband Internet connections either at home or work is growing steadily. This can be explained both by the emergence of rich content applications and by the drop in access prices due to the broadband technologies' evolution and the fierce competition between access networks operators. The current trend in wired access networks are FTTx optical technologies (Fiber To The Home / Curb / Building / Premises), which present an alternative to xDSL networks (using copper loops deployed primarily for the phone system) and cable networks (using cable infrastructures originally deployed for TV distribution). The optical access networks differ first by the physical medium used to carry information. In the case of optical access networks, it is fiber, which have the largest capacity of all physical media used today. Using such a physical medium would potentially provide more bandwidth to the subscribers. However, optical access network architectures raises many issues. For economic reasons, it is necessary to limit both civil engineering (which cost is dominant), and the number of active equipments (which cost more than passive equipment from CAPEX and OPEX points of views). A popular solution is to deploy a tree architecture, and to focus the intelligence of the access network (active elements) at the root of the tree: this corresponds to a Passive Optical Network (PON). The absence of active equipment in the terminals, and the sharing of transmission capacity of fiber among several users, especially for upstream traffic, require the implementation of mechanisms used for controlling multiplexing. These mechanisms are implemented in MAC protocols, which are the main subject of this thesis. Downstream traffic is broadcasted and each end-point filters its own traffic. On the other hand, upstream traffic has to be controlled in order to avoid collisions. The present thesis presents mechanisms that can be implemented in a MAC for Ethernet PON (EPON) in order to control upstream traffic. We show that the proposed mechanisms can support multiple classes of traffic, can couple resource allocation with access control and can finally efficiently use the upstream capacity of the EPON. The various mechanism proposed in the present work are mostly analyzed by simulation; this is because the overall behavior of a PON is too complex to be analytically analyzed, except for simple studies reported in Chapter 3. A comprehensive simulation framework, based on Network Simulator, has been designed and is presented in Chapter 4. This framework has enabled the comparison between state of the art mechanisms and our proposals. We show in Chapter 5 that our mechanisms are simple to implement and behave significantly better than classical mechanisms regarding real time traffic support, while ensuring a quasi-optimal use of upstream bandwidth. More generally, we show in Chapter 6 how our mechanisms are part of a global command plane for PONs. Conclusions and perspectives are outlined in Chapter7

Texte intégralThis research discusses the emergence, the formalization and the institutionalization processes of the Environmental High Quality (HQE) Buildings' standard in France.In 1992, the Environmental High Quality (HQE) approach was initiated in a workgroup of the Ministry of Housing and supported by public administration sector. An HQE Association was created in 1996 to promote and develop the approach. It was conceived as a “standard-based organization with the purpose of supporting one certain standard” (Brunsson & Jacobsson 2000: 50). Thus the HQE association's first mission was to create a reference defining environmental building quality that, in turn, would allow for a common language among actors in this field. The first version of the HQE standard is published in 1997 by the Association. It specified building characteristics, its tools and other elements of the building process, controlling the exterior environmental impacts and creating healthy conditions inside houses. In 2005, the certification of the HQE approach is launched. Progressively the certification of the HQE approach met a great success both in the public and private se ctors. Finally, in less than fifteen years this approach became the French standard of the Environmental Quality of Buildings.Standardization is not just a technical process but “thoroughly political process” (Olshan 1993: 320). Standards set the question about the political role played by experts in the performation of markets (Callon 1998). We claim that a research focused on the standardization-making is relevant to explain knowledge dynamics and markets innovation.Following the emergence of new environmental rules in the French building sector allows us to analyse the process of “standardization-making” by collective professional actors. Three main conclusive findings can be stressed :- The process of « standardization-making » don't essentially take place within the official standardization Agencies (as AFNOR). Collective professional actors take an important part in the process of “standardization-making” by operating as “institutional entrepreneurs” in emerging fields.- Within the process of “standardization-making”, collective professional actors fix new jurisdictions to shape the system of profession (notably the jurisdiction of Architect is reduced by the HQE advisors).- Standardization performs the markets by introducing and legitimating new rules and creating new Business Models (notably with the certification process)

Texte intégralL'hydrodiffusion générée par micro-ondes est une nouvelle technique d'extraction mise au point au sein de l'Université d'Avignon et des Pays de Vaucluse. Ce procédé est une combinaison entre une technique traditionnelle et une technologie innovante. En effet, le chauffage par micro-ondes a permis d'initier et de générer le transfert de matière et de chaleur de l"intérieur des matrices végétales (oignons) vers l'extérieur et de réduire de façon considérable les temps d'extraction des antioxydants sans aucune intervention de solvant. A titre de comparaison, les polyphénols de différentes variétés d'oignons ont été extraits par l'hydrodiffusion générée par micro-ondes et par la technique conventionnelle, l'extraction par solvant. Les rendements obtenus par micro-ondes sont presque identiques à ceux obtenus à l'aide d’un solvant alors que les temps d'extraction sont réduits. La capacité antioxydante des extraits micro-ondes est supérieure à celle obtenue par technique conventionelle. Ce qui présage des potentialités d'application dans le domaine agroalimentaire en particulier pour la valorisation des co-produits. Une étude cinétique de l'extraction, ainsi qu'une observation au microscope optique(cytologie) des matrices traitées soumises aux micro-ondes et au solvant ont mis en évidence la spécificité de l'extraction sans solvant assistée par micro-ondes au niveau des mécanismes de libération et d'extraction des molécules antioxydantes au sein du végétal. L'effet des micro-ondes a pour conséquence une libération plus rapide des principes actifs contenue dans la plante grâce à l'ouverture quasi instantanée des glandes et l'explosion des cellules. L'explication de la différence de composition chimique entre les procédés d'extraction par solvant et par micro-ondes pourrait être basée principalement sur des phénomènes de solubilité, de polarisation diélectrique ainsi qu'un transfert de matière et de chaleur inversé

Texte intégralThe objective of this project is to optimize the evaporation of small fruit liquid extracts, a crucial step in the transformation process of nutraceutical extract production in order to increase its energetic efficiency while keeping a good product quality. The impact of temperature (55, 65 and 75°C) was studied over 3 main parameters; the energetic consumption, the vaporization rate and the extract quality. Its consumption was calculated based on measurements made on the state of the system and on the product. The vaporization rates were measured with level differentials on retention tanks and the product quality evaluation was based on the Folin-Ciocalteu method. For the energetic consumption, they increase from 0.358 to 0.373 kWh/l when passing from 55 to 75 °C. For the vaporization rates, they increase from 462 l/h to 902 l/h when passing from 55 to 75 °C. As for the quality, none of the extracts presents signs of deterioration.
