The space mission PEGASE, proposed to the CNES (Centre National d'Etudes Spatiales = French Space Agency) in the framework of its call for scientific proposals : "formation flying missions", is a 2-aperture interferometer, composed by 3 free flying satellites (2 siderostats and 1 beam combiner), allowing baselines from 50 to 500 m in both nulling and visibility modes. With an angular resolution of a few mas and a spectral resolution of several tens in the spectral range 2.5-5 microns, PEGASE has several goals:science : spectroscopy of hot jupiters (Pegasides) and brown dwarves, exploration of the inner part of protoplanetary diskstechnology : validation in real space conditions of formation flying, nulling and visibility interferometry concepts.PEGASE has been studied at a 0-level. In this paper, we summarize the scientific program and associated technological and mission trade-off coming from this 0-level study. We also discuss how PEGASE can be considered as a TPF/DARWIN pathfinder in an international roadmap towards more complex space interferometry missions such as DARWIN/TPF. [less ▲]

Computer simulations of metal forming processes using the finite element method (FEM) are, today, well established. This form of simulation uses an increasing number of sophisticated geometrical and material models, relying on a certain number of input data, which are not always readily available. The aim of inverse problems, which will be considered here, is to determine one or more of the input data relating to these forming process simulations, thereby leading to a desired result. In this paper, we will focus on two categories of such inverse problems. The first category consists of parameter identification inverse problems. These involve evaluating the material parameters for material constitutive models that would lead to the most accurate results with respect to physical experiments, i.e. minimizing the difference between experimental results and FEM simulations. The second category consists of shape/process optimization inverse problems. These involve determining the initial geometry of the specimen and/or the shape of the forming tools, as well as some parameters of the process itself, in order to provide the desired final geometry after the forming process. These two categories of inverse problems can be formulated as optimization problems in a similar way, i.e. by using identical optimization algorithms. In this paper, we intend firstly to solve these two types of optimization problems by using different non-linear gradient based optimization methods and secondly to compare their efficiency and robustness in a variety of numerical applications.

Evolutionary algorithms are robust and powerful global optimization techniques for solving large-scale problems that have many local optima. However, they require high CPU times, and they are very poor in terms of convergence performance. On the other hand, local search algorithms can converge in a few iterations but lack a global perspective. The combination of global and local search procedures should offer the advantages of both optimization methods while offsetting their disadvantages. This paper proposes a new hybrid optimization technique that merges a genetic algorithm with a local search strategy based on the interior point method. The efficiency of this hybrid approach is demonstrated by solving a constrained multi-objective mathematical test-case. [less ▲]

Haptoglobin and serum amyloid A are major acute phase proteins in cattle. Dairy cattle often develop pathologic conditions in the peripartum period; acute phase proteins may be useful in their diagnosis. Objectives: The purpose of this study was to compare the accuracy of serum haptoglobin (Hp) and serum amyloid A (SAA) concentrations with clinical health status for diagnosing disease during the peripartum period in dairy cattle. Methods: Dairy cows from 4 herds were evaluated every 15 days over a 6-month period. Health status was determined by thorough clinical examination. Haptoglobin and SAA concentrations were measured in serum using validated methods and the results were classifed as positive or negative based on defined cutoff points. Disease prevalence, sensitivity, and specificity were compared using clinical examination as the gold standard. Results: A total of 1896 samples from 158 cows were analyzed. Significant increases in mean Hp and SAA concentrations were observed in the week following parturition in both primiparous and multiparous cows, although high interindividual variability was observed. Both Hp and SAA had low sensitivity but higher specificity in determining disease status compared with clinical examination. Increased concentrations of Hp and SAAwere found in ,10% of samples from clinically healthy cows, except in the week after parturition. Conclusions: Haptoglobin and serum amyloid A should be used with caution as markers of inflammation in the week after calving. Poor sensitivity in other postpartum periods could be related to the higher incidence of chronic (vs acute) inflammation. Haptoglobin may be appropriate for routine screening, but further work needs to be done to assess its value as an indicator of herd health. [less ▲]

For the past few years the inhabitants of a hamlet on the outskirts of the village of Ingleton in Yorkshire, England, have been witnessing a strange exercise every morning. A woman, said to have been one of the most renowned primatologists in the English-speaking world, spends her day in a field in front of her house, observing animals that she has put there. As she did during her many years of field work in Africa studying apes, primatologist Thelma Rowell patiently notes all the movements, anecdotes and tiny events making up the daily social life of the animals to which she is currently devoting her time. Admittedly, these animals are different to the ones she was used to spending time with: the relations are not characterized by the same intensity, the behaviors are peculiar to the species, the communication does not always pass by the same channels, and the events seem to take place at another pace. But as far as their social expertise is concerned, these animals are certainly on a par with apes. [less ▲]

We are currently involved in a Franco-Thai program devolved to a multidisciplinary investigation of Muridae rodents (‘‘mice and rats''), their parasites and the pathogens that they may carry and/or transmit to human, with a better understanding of diseases emergence as an ultimate goal. In such a context, pathogens circulation in the wild is a complex but pivotal phenomenon which requires a continuum of scientific approaches to be accurately apprehended. In particular, a rigorously comparative study is mandatory in order to take into account the interactions between parasites, wild and domestic hosts (uncluding human) and their environment. This is the reason why we rely on both concepts and techniques from a wide range of disciplines including taxonomy, cytogenetics, phylogenetics, phylogeography, population genetics, ecology, geography as well as modeling. With the following objectives. Objective 1: To precisely identify and characterize the rodent species acting as reservoirs, and to document their ecology, geographic distribution as well as the genetic structure of their populations. To assess parasite and pathogen diversity in relation to their associated rodent hosts. To provide cophylogenies and co-phylogeographies in order to enlight the evolutionary relationships of hosts and parasites. Objective 2: To map and correlate the observed rodents distributions with their species-specific environmental landscapes in order to extrapolate their potential ‘‘real'' range and to anticipate their future distributions in relation to landscape modifications. Objective 3: Computing epidemiological databases. Crosschecking field data and GIS data. Definition and standardization of a risk-scale. Finalization of maps of risks and distributions. Atlas of Thai Muridae. Reference collection of Thai Muridae. Education and training of students. Following the listing of the objectives, we expose the first results of our studies and we sketch future projects. [less ▲]

This paper deals with the quasi steady-state approximation of the long-term dynamics. This fast time simulation method assumes that the short-term dynamics are stable and can be replaced by their equilibrium equations. When the latter stop having a solution, the simulation undergoes a singularity. This paper proposes a method to identify which component(s) are responsible for the loss of equilibrium. The corresponding equations are identified using the Newton method with optimal multiplier. The method has been validated with respect to full time simulation. Very good results are shown on the Nordic-32 system, in cases where long-term voltage instability triggers loss of synchronism. The proposed method enhances time simulation at very low computational cost and can also help correcting model and/or operating point errors. [less ▲]

L'année 2004 fut celle de l'anniversaire du deuxième centenaire de la mort d'Emmanuel Kant. Les deux Centres de recherche des Universités de Lecce et de Paris-Sorbonne qui collaborent habituellement dans le domaine des études cartésiennes et, plus généralement, de l'histoire de la philosophie moderne, ont à cette occasion associé leurs efforts pour rendre un hommage commun au philosophe allemand, tout en demeurant dans leur domaine privilégié d'investigation. Ce livre contient les travaux issus des deux rencontres internationales qui en ont résulté. Le titre choisi peut dérouter : sa correction grammaticale comme son sens ne vont pas de soi. - De quels noms propres s'agit-il ici ? Evidemment pas de ceux des individus empiriques, qui s'ignoraient, mais de ceux qui désignent, matériellement, deux corpus de textes. Leur confrontation pourrait faire apparaître un complexe idéal de questions, de concepts et de thèses dans ce qu'on appellera, suivant toute l'indétermination des termes, un système de pensée. Autrement dit, l'un et l'autre se répondraient, à un siècle et demi d'écart, sans discussion directe, mais dans la sauvegarde des mêmes interrogations. Quel point de concours réunirait, sans confusion mais sans métaphore, le corpus qu'identifie la marque " Descartes " et celui dont l'étiquette porte le nom de " Kant " ? Il ne s'agit pas seulement d'étudier des questions communes, d'éventuelles polémiques, voire d'hypothétiques influences entre Descartes et Kant. Il est plutôt question, finalement, de reconnaître dans quelle mesure Kant renouvelle le moment cartésien, en sorte que, lorsque Kant pense, Descartes s'avance encore, caché. Caché et déguisé en Kant - Descartes en Kant, comme le portrait de l'artiste en jeune homme. [less ▲]
