Full textThe quality of finished products is one of the most important concerns of manufacturers. In fact, surface integrity is strongly related to several machining parameters such as cutting conditions, environment and especially tool wear evolution. The latest has been the subject of many researches during last decades but the majority of them were based on experimental tests and still valid for restricted cutting conditions. The lack of efficient models to simulate tool wear is explained by the fact that it is a complicated phenomenon to deal with due to different origins it can result from (abrasion, diffusion, adhesion…). In this context, the main purpose of the proposed research work is to develop a Finite Element Model based on the commercial code ABAQUS© to simulate wear phenomenon of an uncoated tungsten carbide tool insert. The study focuses on the case of orthogonal cutting operation of AISI 4140 and studies the impacts of tool wear on final functional surface integrity. The developed cutting model is based on a lagrangian description of the mesh movement. A damageable zone in the workpiece is considered to simulate the chip formation. Since tool wear occurs after several minutes, a procedure to increase the machining time simulated, named “VErtical Modeling of CUTting” (VEMCUT), is developed. The wear occurred on tool insert is taken into account by the implementation of the Archard law in Abaqus. Wear depth values are computed on each node of tool surface then a procedure for tool nodes relocation is applied. Wear coefficient needed for calculation is determined via non-lubricated experimental wear tests
Kady, Charbel. "Managing Business Process Continuity and Integrity Using Pattern-Based Corrections." Electronic Thesis or Diss., IMT Mines Alès, 2024. http://www.theses.fr/2024EMAL0014.
Full textThis thesis presents an approach to managing deviations in Business Process Model and Notation (BPMN) workflows. The research addresses the critical need for effective deviation management by integrating a comprehensive framework that includes pattern-based deviation correction and an enriched State Token mechanism. The approach is tested through a case study in the apiculture domain, demonstrating the practical applicability and effectiveness of the proposed method. Key contributions include the development of a library of patterns, the characterization of BPMN elements, and a mechanism to help decision-making in addressing deviations. The results show that the approach can efficiently correct deviations, ensuring workflow continuity and integrity

Full textBreakdown of allochtonous leaf litter governs the functioning of headwater streams. These streams are exposed to multiple anthropogenic stresses whose consequences were examined in field (23 streams in South-Western France) and laboratory experiments. Leaf litter breakdown rate responded to alterations of physical and chemical characteristics of stream water and diversity of the riparian vegetation which affect the activity of leaf decomposers. Loss in riparian tree species noticeably lowered trophic dynamics in detritus food webs by modifying interactions among two consumer guilds (leaf-shredding invertebrates and saprophyte aquatic fungi) and the basal resource (leaf litter). Proliferation of an exotic species (Japanese Knotweed) within the riparian vegetation enhanced indigenous leaf litter breakdown as a result of changes in shredder assemblages. The relationship between shredder diversity and leaf litter breakdown rate was also highlighted in streams representative of a gradient of eutrophication (enrichment in dissolved inorganic nitrogen and phosphorus). This indicates the limitations of functional assessment schemes only based on invertebrate traits. Overall, the present results showed the sensitivity of leaf litter breakdown and associated decomposers, to anthropogenic disturbance of streams and associated riparian zones. In this respect, this ecological process appears to be an excellent multimetric indicator of headwater stream health which can discriminate among various types and levels of anthropogenic stress

Full textEnterprise engineering is concerned with the design of projects which aim to improve the structure and behaviour of organisations producing goods and services. It develops approaches based on modelling techniques, particularly on business process modelling in order to assure the quality and the global consistency of the project portfolio. Nowadays, risk consideration in enterprise engineering is a growing importance since the business environment is becoming more and more competitive and unpredictable. In fact, reference frameworks providing guidance for enterprise risk management are developed to tackle this. Our research focuses on risk driven business process design as an integral part of enterprise engineering. After delivering a synthesis of work related to risks and business processes, a research question concerning the integration of both has been addressed. A framework for the integrated management of risks and business processes is suggested. It is based on three components: a coordination of risk and business process management lifecycles, a unified conceptual framework supporting information exchanges between the coordinated lifecycles, and finally a modelling language adapted to the description of risky situations. The later extends the features of a commercial modelling tool (ARIS Business Architect). A case study from the health sector illustrates the foundation of the methodological framework
Chebbi, Hela. "Le pilotage du processus intégré d'innovation de service au sein des multinationales : le cas France Télécom." Lyon 3, 2008. http://www.theses.fr/2008LYO33004.
Full textA consensus exist around the importance of the integration of subsidiarie's knowledge to propose services with elevated technological components (SWETC) simultaneously on several overseas markets (Subramaniam, 2006). The steady thesis is that this iniative joins within a transnational strategy based on an integrated process of innovation. We led a longitudinal empirical investigation ( two years) within the multinational France Telecom. The discussion of the results shows that the conduction of such process requires taking into account three different factors : the organizational strategy, the strategy of service innovation and the international strategy. For the first one, a hybrid organizational configuration, such as the " adhocratic with linked products” seems to be more adapted for multinationals. For the innovation strategy, the involvement of subsidiaries from the beginning of the process is necessary. To propose multi-country services, the mobilization and opérationnalisation activities deserve to be collectively led by the headquarters and subsidiaries. In this frame, four types of local knowledge can be integrated : needs, constraints, results and commercial knowledge. Both first ones join a context of exchange ( additive complementarity). The third type is essentially transferred in a frame of collaboration (sequential complementarity). Finally, the analysis testifies of the utility to implement a different international strategy as the transfer of knowledge joins a context of exchange or collaboration. This descriptive stage was completed by a crossed analysis of the obtained results. A "framework", based on a set of propositions (six epistemic, thirteen theoritical and twenty operational), will drive the strategists and the managers of multinationals in the management of the innovation process

Full textSuccession of the family business is an issue that continues to be of great interest to researchers and practitioners because of its perilous nature. Although some studies have considered the succession in family businesses from a knowledge based approach, the existing theoretical deficiencies needs further studies. This research aims to formulate a better understanding of the process of knowledge transfer that takes place within the succession process of family businesses. A better description of this process and its features in time provides family and professional actors involved in the training of successors useful knowledge. Futhermore, the formalization of the steps are likely to guide the action of family businesses that prepare succession. To this end, an empirical investigation of family business successors was undertaken using narrative method. The qualitative data analysis was carried out by complementary techniques : diachronic, thematic and comparative analysis. As a results an integrated process of successor’s development in family businesses, which is carried out in three stages, marked out by influencing factors, transfer methods, actants, critical events and disruptive elements. This dynamic process brings out temporalities and describes, through the use of the theatrical metaphor, a rise in the stage of the successor in order to obtain the role of leader

Full textCyber attacks are based on intrusions into digital systems by exploiting bugs to take control over the system. Many protections have been developed to thwart cyber attack, among them we can quote code obfuscation, memory integrity check, instruction set randomization, address space layout randomization (ASLR), canary, sand boxing, process isolation, virtualization and access right restriction. Modern processors provide security by zone isolation systems (Protection ring, MMU, NX bit, TrustZone), Control Flow Integrity (CFI) is a new technique proposed by Abadi et al. to mitigate program corruption. This technique gave rise to many implementations but none are complete, fast and easily incorporable to existing processor. This thesis is inspired from previous work on HCODE which implements code integrity by computing signature for each executed basic block. HCODE is an hardware block designed to be plugged in read only on the interface between the processor and the instruction cache. In this thesis we present CCFI solution, improvement of HCODE, which is now able to provide Code Integrity and Control Flow Integrity. We propose CCFI architecture able to protect direct and indirect jumps as well as interruptions. The proposed solution is based on both hardware modules and software modifications to ensure speed and flexibility of the solution. To ensure a full CFI protection metadata are embedded with the code. These metadata describes the Control Flow Graph

Full textEnterprise Resource Planning (ERP) is constructed by a team and is used by actors who did not participate in his conception : the final users (UF). A theoretical exploration on appropriation of ERP by UF was made. This exploration rests on the study of the notion of appropriation from disciplines in Human and Social Sciences which use this term and, on studies of Sciences of Management on ERP. A conceptual model about appropriation of ERP was created from this exploration. Then, we formulated the following question : What are the factors that influence the appropriation process of ERP by UF towards the best waited practices? Factors of influence were found in literature, all categories taken together. A case study is essential to analyse the different phenomena of the conceptual model and to answer our question by pre-empting or by confirming the factors which were found in literature, but also by discovering other factors. The results show that the appropriation process begins by three different status and this is by the interrelationship of individual, contextual, technological factors and actions set up by other actors that the appropriation process of ERP by UF gives rise to best waited practices. A causal model is offered

Full textThe objective of this thesis is to study the links between the installation of ERP and the management control process. It is in particular a question of looking in which measure the various facets of control evolve further to the introduction of an ERP. It is mutually a question of wondering about the way the control process direct possibly the introduction and the evolution of ERP. The combination of qualitative and quantitative research methods suggests a bigger autonomy of the operational managers in the access to the data. ERP seem to allow them to elaborate, more completely and in a more reliable way, the performances representations necessary to manage their center of responsibility. ERP so entail a wider and better understood diffusion of management control terms in organizations. The operational managers seem to remain nevertheless sometimes dependent on management controllers to understand or interpret the data, indeed to coordinate with the other executives. Freed from routine tasks of data collection, the management controllers seem to be so brought to direct more strongly choices in management of the middle managers. The installation of ERP so tends to clarify and to develop the role of translator and agent of the management controllers

Full textThe purpose of this work is to give a thorough analysis on the exchange risk management system in the international enterprises, and, the most important, to improve the performance of this system by introducing the econometrical tools. For this purpose, the ARFIMA-FIGARCH econometric model has been introduced and applied to the exchange rate series of the “Great Six” with the presence of the long memory phenomenon. A comparison of the predictive ability has been made between ARFIMA-FIGARCH model and random walk. Our results suggest that the efficiency hypothesis of the exchange market would be strongly questioned. Application of such result to exchange rate would improve significantly hedging methods

Full textCombining grinding with burnishing called “REGAL” is a newly developed outstanding technique consisting in grinding and burnishing operating simultaneously. The purpose behind this innovative approach is to enhance the surface integrity of the workpiece obtained by REGAL if compared to grinding and burnishing performing each one apart. REGAL process is made possible thanks to the design and manufacturing of a mechanical fixing system capable of maintaining the burnishing ball next to the grinding wheel. An automated control table is needed to make small and precise lateral feeds in order to ensure high surface recovery rates obtained by the ball burnishing tool. The most influential parameters of REGAL process were identified and their impacts on surface integrity were studied in terms of forces, roughness and residual stress results. The experimental results have shown that further from gaining time and energy by combining two processes in one, REGAL process enhances drastically the quality of the surface obtained if compared to workpiece surfaces obtained after grinding and burnishing acting separately. In addition, simultaneous grinding and burnishing introduces compressive residual stress results at the surface and beneath it reaching a deeper depth than the depth obtained by burnishing at the same manufacturing conditions thanks to the physicochemical changes obtained by the simultaneous thermomechanical/purely mechanical loads applied to the workpiece. 3D numerical simulations of grinding, burnishing and REGAL were also conducted to understand the physical phenomena occurring that is responsible of getting a more compressive residual stress layer obtained by REGAL if compared to burnishing acting separately and are in adequacy with the experimental results

Full textThis work deals with the quantitative and environmentally friendly destruction of concentrated nitrates solutions using two different processes. In both cases, the nitrates solution was firstly reduced electrochemically into ammonium on a porous copper electrode. Whatever the initial pH of the electrolytic solution, a high ammonium selectivity was obtained. In the first process, the ammonium was subsequently oxidized to nitrogen gas by hypochlorite ions generated electrochemically. An excellent selectivity of 91.5% with high current efficiency and high chemical yield toward the nitrogen formation was recorded, with a low power consumption. The second method is an electrochemical / biological coupling process where the obtained ammonium solution will be used as a nitrogen source to produce biohydrogen (H2) via heat-treated sludge cultures. A complete assimilation of the ammonium solution resulting from the electroreduction of nitrate was obtained. A maximum hydrogen yield of 0.35 mol H2/mole glucose was achieved using activated sludge collected from an aeration tank versus 1.1 mole H2/mole glucose produced in the case of sludge taken from an anaerobic digester

Full textIn the design of control systems for complex industrial processes there are needs that cannot be successfully addressed by the existing conventional control laws. In certain situations, the control system must exhibit a degree of autonomy in order to ensure continuity in the task for which it has been designed. In this work, a new approach for the functional architecture of a control system is proposed. The goal of this architecture is to increase the industrial processes autonomy by integrating in the control system the four following functional modules : control functions, knowledge base, inference mechanisms and man-machine interface and communications. Chapter 2 is dedicates to the study of the centrifugation process. The global behaviour is described by an oriented-signed graph taking into account the influence of the different phenomena. Chapter 3 deals with the problem of data-based learning systems. Different learning approaches, such as classification, pattern recognition and regression are presented and applied to the system. The last part of the chapter is devoted to the Takagi-Sugeno type fuzzy models. In chapter 4, the problems of monitoring, fault diagnosis and accomodation are treated. The dualty between parity space approach and principal component analysis (PCA) for fault detection and isolation is shown. In the last part of the chapter, the principles of fault accomodation are exposed and a specific method based on the computation of the faulty system parameters is applied. Finally, the procedure which leads to the integration of the functions to the control system is presented

Full textThe research is aimed at presenting a new integrated approach to aid operators and designers to manage the design process as a whole in refurbishment interventions of recent existing building stock, through the use of innovative technological envelope solutions. The study requires the acquisition of a selection of typological and constructive envelope solutions, as a starting point for the development of design solutions to be used for architectural renovation of schools built after the Second World War, in reinforced concrete and mostly prefabricated. The project identifies sustainable construction processes for the design of “active”, adaptive, efficient and dry assembled envelope components, in accordance with the performance requirements prescribed by current regulations. The purpose of the research is to manage the whole design process with the support of geometrical survey, connected to parametric programming software for modelling surfaces which can be adapted to the morphology of existing buildings. These computerized CAD-CAM tools are connected to CNC machines for “customized” industrialized production. To illustrate this innovative approach, two envelope solutions are proposed, according to the research paradigms and the principles of sustainability, meant as modularity, speed of setup, reversibility, recycling and reuse of materials with low environmental impact. In particular, the innovative solutions have in common the application of a technique based on the assembly of prefabricated components, the adoption of hexagonal patterns for the tessellation of the new surface of the façade, and the use of the same plastic and inorganic, recycled and sustainable, thermal insulation material (AAM-Alkali Activated Materials).The design solutions proposed are developed at the two sites involved in the joint

Full textRecurrent defects appearing in specific contexts have a significant impact on nanoscale technology nodes manufacturing process yield. Therefore, a new in-situ process monitoring method is developed to improve the overall performance of the production tool. It is complementary to classical failure analysis techniques, especially when a yield crisis occurs. The idea is to transform a production circuit into a test vehicle by reusing its components. The circuit loses its original functionality in favor of process monitoring functions, carried out only with standard cells widely available in circuits. This transformation, called "topological exchange" involves modifying some levels of metallization and requires the creation of a particular design flow, based on Engineering Change Order (ECO) techniques. As several functions must be able to cohabit on the same vehicle, a multiplexing system is evaluated. Feasibility is shown through a test circuit designed analogously to a production circuit. It is transformed for the example into an integrated dielectric thickness control system

First of all, a reverse engineering methodology was developed to understand the role of oilseed native surfactants in the stability of oil-bodies in water. Subsequently, using a general approach, it was possible to develop a process that allows releasing the lipid fraction into an emulsion. If an in-situ enzymatic hydrolysis of triglycerides is added to this process, an emulsion containing the free fatty acids will be obtained. The activity of the remaining lipase in the emulsion was used to study the esterification of free fatty acids with different alcohols using a three-phase partitioning method

Full textThis work is focused on improving the biospecificity properties of fluorescent polymer probes, with controlled architectures, for two main applications: the in vivo targeting of cancer tumors and the labeling of proteins for in cellulo studies. For a targeted imaging of tumor angiogenesis in vivo, targeting systems presenting two levels of multivalency were developed by combining both i) well-controlled polymers synthesized by RAFT polymerization and the PISA process, ii) peptide tetravalent clusters exhibiting a high affinity for the αvβ3 integrins and iii) fluorophores emitting in the far red / near-infrared for a monitoring in vitro and in vivo by optical microscopy. Two types of probes were synthesized, linear conjugates and hairy nanoparticles. Multivalent presentation of the peptide cluster induced a significant increase of the affinity for αvβ3 integrins. The first biological evaluations also indicated an efficient cellular internalization of polymer probes mediated by the peptide clusters and a selective labeling of cells over-expressing αvβ3 integrins. For protein labeling, two strategies were explored: the labeling of native proteins by covalent coupling of ω-functional polymer probes and the labeling of recombinant proteins by probes bearing a specific ligand at one chain-end. For the first strategy, an activated ester function was introduced at the ω-end of polymer probes by thiol-ene chemistry to label the lysine residues of native proteins. This approach resulted in a poly-labeling, difficult to control but providing highly bright bioconjugates. For the second strategy, a nitrilotriacetic acid group (NTA) was introduced at the α-end of polymers probes to specifically label Histidine tagged proteins. This approach enabled an efficient labeling of different proteins with a more precise control of the number of probes per protein and of the binding site. Finally, following this work, a new synthetic strategy of sequenced polymers by successive addition of hetero-bifunctional monomers using highly efficient, selective and orthogonal chemical reactions was proposed and validated

Full textThis innovative work studies the interest of integrating piezoelectric transducers (ceramic and/or polymer-based) within Polymer- Matrix Composite materials (PMC) to perform real-time and in-situ monitoring of their manufacturing process (Process Monitoring PM) as well as their lifespan (Structural Health Monitoring SHM). To do this, the piezoelectric transducers were integrated into the heart of the fibrous stacks using an innovative methodology developed within the "Materials and Surfaces" research team at the Roberval laboratory. The Liquid Resin Infusion (LRI) manufacturing system used (PM campaign), as well as the resulting samples tested mechanically (SHM campaign), were multi-instrumented using several Non-Destructive Testing devices (NDT: Acoustic Emission (AE), Infrared Thermography (IRT), Digital Image Correlation (DIC), etc.) in order to establish multi-physical couplings between the signals of external NDT techniques and the internal signature (electrical capacitance) coming from the transducers integrated into the heart of the material. In PM, the piezoceramic (PZT) transducers were found to be sensitive to the various key steps of the LRI process (flow front passing, impregnation, end of injection, chemo-physical transitions during curing and associated consolidation rates) achieved at different hardener rates, and able to detect manufacturing defects. These results showed great potential, worthy of future use on an industrial scale. In SHM, after verification of the non-intrusiveness of the ceramic and polymer-based transducers integrated into the heart of the mechanical test specimens, the polymer transducers allowed a real-time evaluation of the triaxial strain state and the rigidity loss experienced by the host PMC during its mechanical loading. However, despite a Non-Working Threshold (NWT) linked to the brittleness of their constitutive material, the piezoceramic transducers have shown a high sensitivity to the detection and monitoring of damage in real-time when they are positioned intelligently with respect to the mechanical stress. These thesis works ended with a first attempt aimed at transposing the knowledge acquired on PM and SHM of in-situ piezoelectric transducers from a 2D “laboratory” scale to a 3D structural one closer to industrial realities. The multi-instrumented manufacturing of an “Omega” stiffener PMC structure integrating 14 piezoelectric transducers (PZT and P(VDF-TrFE) copolymer) and reinforced through-the-thickness by a carbon tuft thread allowed confirming the previously evidenced PM abilities of the PZT, and showed a difference between how the electrical capacitance signals of PZT and copolymers react to the whole manufacturing process
