DUMONCEL, JEAN CLAUDE. "Le systeme de whitehead et la philosophie analytique." Nantes, 1987. http://www.theses.fr/1987NANT3020.
Повний текст джерелаThe speculative scheme of whitehead is here provided with a translation in the language of analytical philosophy. F. B. Fitch's pionneering use of combinatory logic with the same purpose serves as a paradigm, but the emphasis is placed on modal logic, understood in the manner of hintikka, that is as a general tool for characterizing philosophical concepts. E. G. , whitehead's notion of "propositionnal feeling" is here considered under russell's notion of propositional attitude. The obtained apparatus is then tested on two selected topics in the field of fundational studies : first, the problem arising from the divergence between frege and fitch on the fundamentals of "pure grammar"; second, the problem of interpreting quantum mechanics. The solution offered to the first problem (i. E. The way of combinatory logic) and the one proposed for the second problem (i. I. Wave mechanics as it is understood by de broglie and popper) are each conceived as a case of "creativity", the ultimate category of whitehead's metaphysics, thus showing the overall unity of the entire system. In the course of the whole enterprise, the tradition leading from plato to whitehead, via leibniz and charles-sanders peirce, requires to be mobilized, and shows its living power by the way

Повний текст джерелаIn eucaryotic cells, DNA double-strand breaks are repaired through two main pathways : the homologous recombination and the non homologous end joining . Altough these pathways are well characterized, two particular aspects of the repair remain poorly understood :- If two separated pathways may occur in the cells, which mechanism(s) govern the choice of the pathway that will ultimately lead to the repair ?- If the double-strand break is induced by ionizing radiations – as those employed in anti-cancerous radiotherapy – how does the repair occur if the DNA ends at the edge of the break are not compatible with a direct ligation ? A proper knowledge of the proteins involved in this repair would allow the development of additives, useful to increase the efficiency of the radiotherapy.To investigate these questions, we designed a new analytical system allowing : 1) the specific recruitment of DNA double-strand break repair complexes on home-made chromatographic phases, 2) the separation of these complexes in a non-denaturing polyacrylamide gel and their subsequent visualization and 3) their biochemical characterization.The methodology developped in this work has been focused on the following points : 1) we designed and implemented a chromatographic system allowing the distinction between proteins recruited onto duplex DNA oligonucleotide with free DNA ends (mimicking DNA double-strand breaks) and proteins fixed onto the internal sequence of the same oligonucleotides ; 2) we adapted to our problematic a methodology of non-denaturing electrophoresis thus allowing the separation of the purified complexes while guaranteeing their integrity during the migration, 3) we also determined their composition by mass spectrometry after their visualization.The biochemical study has shown that the purified complexes were still functionnal, that is they were able to efficiently ligate two oligonucleotides. The study of the data provided by the mass spectrometry analysis of independant experiences proved that the complexes belonged to the DNA physiology and were especially representative of the diversity of the DNA repair pathways.Interestingly, we observed that some of the protein specifically recruited onto the the double-strand breaks were not known to be involved in the DNA repair (nucleotide synthesis, checkpoint, DNA topology, cytoskeleton).The rôle of these proteins should be characterized in cellulo especially with siRNA. On the other hand we will also use the methodological development described above to study the repair mechanisms of radio-induced DNA double-strand breaks occuring in the irradiated tumorous cells. To achieve this study we will elaborate new chromatographic phases with pre-irradiated oligonucleotides

Повний текст джерелаIn this document, we have studied the diesel engine vacuum pump drive non linear dynamics. The involved double-sided contact is represented by a classical torsion stiffness and a viscous torsion damping. The piecewise linear motion equation obtained is solved by a semi analytical method. A continuation technique, based on a semi analytical shooting method, is used to describe periodic orbits and their bifurcations. The chaotic behaviour is revealed by the computed Lyaopunov exponents and Poincaré applications. Finally, an experiment idealizing the vacuum pump system has been performed. Experimental and computed results will be confronted to validate the model and the analysis procedure

Повний текст джерелаThe genome of bacteria is classically separated into essential, stable and slow evolving replicons (chromosomes) and accessory, mobile and rapidly evolving replicons (plasmids). This paradigm is being questioned since the discovery of extra-chromosomal essential replicons (ECERs), be they called ”megaplasmids”, ”secondary chromosomes” or ”chromids”, which possess both chromosomal and plasmidic features. These ECERs are found in diverse lineages across the bacterial phylogeny and are generally believed to be modified plasmids. However, their true nature and the mechanisms permitting their integration within the sable genome are yet to be formally determined. The relationships between replicons, with reference to their genetic information inheritance systems (GIIS), were explored under the assumption that the inheritance of ECERs is integrated to the cell cycle and highly constrained in contrast to that of standard plasmids. A global comparative genomics analysis including all available of complete bacterial genome sequences, was performed using GIIS functional homologues as parameters and applying several analytical procedures. GIIS proved appropriate in characterizing the level of integration within the stable genome, as well as the origins, of the replicons. The study of ECERs thus provides clues to the genetic mechanisms and evolutionary processes involved in the replicon stabilization into the essential genome and the continuity of the genomic material

Повний текст джерелаLTCC (Low Temperature Co-fired Ceramic) and gold multilayers systems are extensively used in the development of multi-materials components for civil and military radio-frequency applications. This technology presents a high potential of development because it provides a packaging solution for electronic chips. During the process of drafting of these multi-materials components (ceramic metal), the co-sintering step is a key and critical one, indeed it leads to damages because of potential thermal expansion coefficients and shrinkage kinetics differentials. Thus, the aim of this work is to develop a numerical model able to faithfully simulate the components thermomechanical behavior during the co-sintering stage. To achieve this, the sintering and thermomechanical behavior of the selected ceramic and metal materials have been carefully characterized. The behavior laws so identified have been implemented in the software based on the finite elements method Comsol Multiphysics. The developed model robustness has been analyzed by confrontation with experimental tests driven by the establishment of an original shadowscopy apparatus which allows the in situ strain recording. Thus, the generated curvatures during the constrained sintering of a LTCC bilayer and during a gold-LTCC bilayer co-sintering have been characterized and compared with the numerical simulations

Повний текст джерелаWe aim at developing a complete 3D numerical model of a parturient pelvic system representing all the anatomical structures of the pelvis such as ligament, muscle and organs. Then we generate a parametric FE model that allows simulating normal and dystocic vaginal delivery.We have developed a parturient pelvic numerical model at different gestational ages, 16, 32 and 38 weeks of gestation, (WG) and in postpartum (2months and 1year) from MRI. The different organs, muscles and ligaments of the pelvic system were segmented in order to generate a complete anatomical 3D model. Starting from this numerical model we studied the changes the muscles and ligaments undergo during pregnancy. Then we performed a Finite Element (FE) model that allows simulation and analysis of the deformations of pelvic anatomical structures under the stress induce by normal and dystocic vaginal delivery. In particular, we investigated the influence of the head size, terms and cephalic orientation and flexion. We particularly studied the structures that play an important role in the stability of the pelvic system.ResultsThe analysis during pregnancy of the US ligaments and levator ani muscle (LAM) reveals some geometrical modification, even then at the beginning of the second pregnancy trimester. This 3D anatomical model help to develop a teaching model for manual removing of the placenta, that could be integrated in a simple physic mannequin. The proof of pedagogical interest of this tool was made by different series of tests, underwent by gynaecolog-obstetrician and midwives. Then we worked with FE simulation of the vaginal delivery. The model developed is parametric. Than mean we can then change different maternal and fetal criteria such as gestational age, fetal head size, orientation and flexion. First place we performed normal vaginal delivery to study the impact of the fetal head descent in the pelvic system, and his stress impact on the different anatomical structures. Then we introduce dystocic element. We can evaluate and localize the strain levels and the most injured areas. Posterior cephalic presentation presents higher injury risk than the anterior one. Maternal geometry at different terms brings equivalent results contrary to the fetal head sizes that have an influence on the strain level and the potential damage induced. We developed pressure and trajectories sensors integrated in a forceps. We can then record an ex-vivo forceps extraction and then integrate all the information in the FE model.ConclusionThis multi-parametric investigation allows us to have a customizable and predictive tool evaluating the potential damages on the pelvis during vaginal delivery. We could then explain, understand and maybe predict some maternal and fetal complications that could happen during vaginal delivery. We can in particular try to explain the perinea injuries during, after and long time after vaginal delivery. This tool can be used to teach the complexity of obstetric

Повний текст джерелаThis study on the locomotion of C. Elegans aims at a better understanding of its nervous system and at giving birth to news ideas concerning the conception of new biometics models or objects. We first gave a description of the worm, of its physiology, and of its main modes of locomotion, that is to say the swimming - in liquid medium, and the crawling - on gel substract. When swimming, we analyzed how the dissymmetry pf the movement is necessary for the worm to move on when in viscous medium. Thanks to the analysis of the velocity of the local displacements and by supposing that the forces are viscous, we balanced the forces. We thus demonstrated that transversal and longitudinal friction coefficients could be compared to the coefficients obtained theoretically from an oblong ellipsoïd. When crawling, we were able to observe a diminution of the amplitude from the head to the tail. We first studied the worm-substract interaction theorically - lubrification hypothesis, but the friction coefficients predicted were in contradiction with experimental results. This difference, according to our experiments, was due to static friction. We also measured the rigidity of the worm. By confining the worm vertically in liquid medium, we observed a continuous transition from swimming to — crawling. We proved that the movement of the tail, in comparison with the movement of the head, was more and more delayed as the confinement increased. In these conditions, the global movement of the worm got slower. On substract, we were able to constrain the amplitude thanks to a horizontal confinement; we observed that wavelength decreased with amplitude

Повний текст джерелаDuring the design phase, the different engineering teams make multiple FE simulations dealing with various physical behaviours in order to ensure both verification and validation.However, the unsatisfactory results lead to late changes and hence to long iterations and increasing costs.In order to tackle this problem, it is essential to take into account the geometrical and multi-physical constraints in the complex system architecture since the conceptual design phase.In fact, a process called SAMOS is developed aiming at selecting the most adequate 3D multi-physical architecture while ensuring an efficient collaboration between the engineering teams. Moreover, this framework is based on two SysML extensions which allow the enrichment of the architecture with geometrical and multi-physical data.Furthermore, this thesis focuses on magnetic constraints and magnetic-thermal coupling.Since this phase does not support long FE simulations, the analytical models based on simplified geometries are sufficient to provide satisfactory approximate results.In this context, different analytical models are studied and validated through FE simulations and measures for several cases such as NdFeB permanent magnets. Indeed, the temperature rise does not only decrease the remanent flux density but is able also to cause irreversible losses. In fact, once we go back to the initial temperature, the characteristics of the magnet are modified. The different factors impacting the demagnetization process are discussed.Besides, the temperature impact on brushless motors’ performances is studied since this device represents a complex mechatronic system

Повний текст джерелаIn the last decade, Networks-on-chip (NoCs) have emerged as an efficient and flexible interconnect solution to handle the increasing number of processing elements included in Systems-on-chip (SoCs). NoCs are able to handle high-bandwidth and scalability needs under tight performance constraints. However, they are usually characterized by a large number of architectural and implementation parameters, resulting in a vast design space. In these conditions, finding a suitable NoC architecture for specific platform needs is a challenging issue. Moreover, most of main design decisions (e.g. topology, routing scheme, quality of service) are usually made at architectural-level during the first steps of the design flow, but measuring the effects of these decisions on the final implementation at such high level of abstraction is complex. Static analysis (i.e. non-simulation-based methods) has emerged to fulfill this need of reliable performance and cost estimation methods available early in the design flow. As the level of abstraction of static analysis is high, it is unrealistic to expect an accurate estimation of the performance or cost of the chip. Fidelity (i.e. characterization of the main tendencies of a metric) is thus the main objective rather than accuracy. This thesis proposes a modeling methodology to design static cost analysis of NoC components. The proposed method is mainly oriented towards generality. In particular, no assumption is made neither on the number of parameters of the components nor on the dependences of the modeled metric on these parameters. We are then able to address components with millions of configurations possibilities (order of 1e+30 configuration possibilities) and to estimate cost of complex NoCs composed of a large number of these components at architectural-level. It is difficult to model that kind of components with experimental analytical models due to the huge number of configuration possibilities. We thus propose a fully-automated modeling flow which can be applied directly to any architecture and technology. The output of the flow is a NoC component cost predictor able to estimate a metric of interest for any configuration of the design space in few seconds. The flow builds fine-grained analytical models on the basis of gate-level results and a machine-learning method. It is then able to design models with a better fidelity than purely-mathematical methods while preserving their main qualities (i.e. low complexity, early availability). Moreover, it is also able to take into account the effects of the technology on the performance. We propose to use an interpolation method based on Kriging theory. By using Kriging methodology, the number of implementation flow runs required in the modeling process is minimized and the main characteristics of the metrics in space are modeled both globally and locally. The method is applied to model logic area of key NoC components. The inclusion of traffic is then addressed and a NoC router leakage and average dynamic power model is designed on this basis

Повний текст джерелаCrater counting is the only method used on Mars to give relative geochronological information but it never had been fitted and corrected by absolute geochronology. This work is about the development of a new prototype demonstrating the ability of a protocol using in situ K-Ar dating. The goal is to propose a solution of an absolute geochronology for the next explorations rovers. A quadrupled Nd:YAG laser at 266 nm ablates a basaltic sample under high vacuum. The light collection by a spectrometer (Laser Induced Breakdown Spectroscopy) gives the rate of potassium and the chemical or the mineralogy of the target. Thanks to the specificities of the ablation in highvacuum and with a UV laser, the ablated mass has a good reproducibility per mineralogy. Thus, theLIBS identification gives an estimation of the ablated mass. After the purification of the released gas,a quadrupole mass spectrometer determines the quantity of argon. All these measures give an age with a theoretical uncertainty of 13% in the best conditions.The calibration of the experiment had given new information about the effects on LIBS spectrarelated to the ablation under high vacuum. The rise of the pressure and the variation of geometry of the pit have opposite effects on the elements peaks. We also demonstrated that the instrument was capable of measuring the age of the groundmass of basalt and has some interesting perspectives on some mineral phases such as biotite

Повний текст джерелаNetworked automation systems (NAS) are more and more used in industry, given the several advantages they provide like flexibility, low cost, ease of maintenance, etc. However, the use of a communication network in SCR means in essence sharing some resources and therefore strikingly impacts their time performances. For instance, a control signal does get to its destination (actuator) only after a non zero delay. So, to guarantee that such a delay is shorter than a given threshold or other time constraints well respected, an a priori evaluation is necessary before operating the SCR. In our research activities, we are interested in client/server SCR reactivity and the evaluation of their response time.Our contribution in this investigation is the introduction of a (Max,+) Algebra-based analytic approach to solve some problems, faced in the existing methods like state explosion of model checking or the non exhaustivity of simulation. So, after getting Timed Event Graphs based models of the SCR and their linear state (Max,+) representation, we obtain formulae that enables to calculate straightforwardly the SCR response times. More precisely, we obtain formulae of the bounds of response time by adopting a deterministic analysis and other formulae to calculate the probability density of response time by considering a stochastic analysis. Moreover, in our investigation we take into account every single elementary delay involved in the response time, including the end-to-end delays, due exclusively to crossing the communication network. This latter being however constituted of shared resources, making by the way the use of TEG and (Max,+) Algebra impossible, we introduce a novel approach to model the communication network. This approach brings to life a new class of Petri nets, called Conflicting Timed Event Graphs (CTEG), which enables us to solve the problem of the shared resources. We also manage to represent the CTEG dynamics using recurrent (Max,+) equations and therefore calculate the end to-end delays. An Ethernet-based network is studied as an example to apply this novel approach. Note by the way that the field of application of this approach borders largely communication networks and is quite possible when dealing with other systems.Finally, to validate the different results of our research activities and the related hypotheses, especially the maximal bound of response time formula, we carry out lots of experimental measurements on a lab facility. We compare the measures to the formula predictions and check their agreement under different conditions

Повний текст джерелаThis thesis focuses on the creation of an expert system for automatic alignment of chromatographic signals in response to a problem of drifts and shifts of signals encountered in the inter-comparison of data in evolving environment. After a state of the art of the different alignment methods that exist in the literature, the performances of freely available methods were tested on sets of simulated and real chromatographic data. At the end of this methodical work, it turned out that none of the methods did not provide fully satisfactory in terms of performance defined in the specification. Thus, an optimization of the best alignment method has been developed so that it can be attached to a software acquisition and processing of chromatographic data. The last part of this thesis deals with a complementary problem, the conformity of the samples in terms of quality control. The similarity of the peaks is evaluated according to criteria developed and validated by manual operation data

Повний текст джерелаThis thesis focuses on the development of a method for the preliminary design of mechatronic systems, taking into account the vibratory aspect, without going through costly design techniques, such as 3D CAD and finite element method.In an early stage of the design process of mechatronic systems, simple analytical models are necessary to the architect engineer in Mechatronics, for important conceptual decisions related to multi-physics coupling and vibration. For this purpose, a library of flexible elements, based on analytical models, was developed in this thesis, using the Modelica modeling language.To demonstrate the possibilities of this approach, we conducted a study of the vibration response of some mechatronic systems. Therefore, the pre-sizing approach was applied in a first phase to a simple mechatronic system, formed with a rectangular plate supporting electrical components such as electric motors and electronic cards, and in a second phase the approach was applied to a wind turbine, considered as a complete mechatronic system. Simulation results were compared with the finite elements method and other studies found in the scientific literature. Simulation results have enabled us to prove that the developed compact models assist the mechatronic architect to find results of simulation with an important accuracy and a low computational cost

Повний текст джерелаIn a first part, we developed a mixed method combining top-down micro-costing and bottom-up micro-costing to accurately assess the costs of organ recovery in a French hospital group. We compared this mixed method versus full top-down micro-costing to assess potential differences. In view of illustration, we applied in a second part the results of pancreas recovery cost to value the islet transplantation procedure. During a third part, we assessed organ recovery costs based on the national hospital discharge database and a national cost study from 8 consecutive years. Results of the first and the second publication, each based on specific database, appear to be widely different. We compared, in a last part, the hospital cost accounting system in a French hospital group with the national cost study in terms of the cost of organ recovery procedures. This study highlights the cost differences existing between hospital cost accounting and the national cost study. These differences relativize and lend caution to the interpretation of the results of our previous study assessing organ recovery cost from national data. Given these differences, it is fundamental for readers, hospital managers and decision-makers to know the strengths and weaknesses of each methodological approach and the strengths and weaknesses of each database used to be able to interpret the results in an informed context

Повний текст джерелаThis dissertation deals with the physico-chemical properties in aqueous solutions of short polyethylene-glycol chains. The aggregation ability of PEG600 has been studied with comparison with PEG400 : these oligomers exhibit a critical aggregation constant apparently resulting from the helical configuration of the PEG chain. The constant value which depends on temperature and appears in dilute solutions, has been determined by tensiometry and confirmed by measurements of fluorescence intensity. The rheological properties of concentrated solutions (more than 50 weight percents) have been studied with a cone and plate rheometer with respect to concentration and temperature. The dynamic viscosity increases with concentration and decreases when temperature increases, with an activation energy of 37 kJ mol-1. Characteristic times decrease when concentration increases and temperature decreases. The corresponding activation energy is between -45 and -17,5 kJ mol-1. The order of magnitude of all the activation energies can be compared with the weak bond energy. The existence of helical structures able to aggregate would be worth to be studied and probably to be better used to realise better stimuli-dependent systems
