    Wavelet and wavelet packet transforms are the most commonly used algorithms for seismic data compression. Wavelet coefficients are generally quantized and encoded by classical entropy coding techniques. We first propose in this work a compression algorithm based on the wavelet transform. The wavelet transform is used together with a zero-tree type coding, with first use in seismic applications. Classical wavelet transforms nevertheless yield a quite rigid approach, since it is often desirable to adapt the transform stage to the properties of each type of signal. We thus propose a second algorithm using, instead of wavelets, a set of so called 'extended transforms'. These transforms, originating from the filter bank theory, are parameterized. Classical examples are Malvar's Lapped Orthogonal Transforms (LOT) or de Queiroz et al. Generalized Lapped Orthogonal Transforms (GenLOT). We propose several optimization criteria to build 'extended transforms' which are adapted the properties of seismic signals. We further show that these transforms can be used with the same zero-tree type coding technique as used with wavelets. Both proposed algorithms provide exact compression rate choice, block-wise compression (in the case of extended transforms) and partial decompression for quality control or visualization. Performances are tested on a set of actual seismic data. They are evaluated for several quality measures. We also compare them to other seismic compression algorithms. (author)

    The aim of the dissertation is the linearized inversion of multicomponent seismic data for 3D elastic horizontally stratified media, using Born approximation. A Jacobian matrix is constructed; it will be used to model seismic data from elastic parameters. The inversion technique, relying on single value decomposition (SVD) of the Jacobian matrix, is described. Next, the resolution of inverted elastic parameters is quantitatively studies. A first use of the technique is shown in the frame of an evaluation of a sea bottom acquisition (synthetic data). Finally, a real data set acquired with conventional marine technique is inverted.

    Full Text Available We present a seismic processing method which shows that it is possible to extract new attributes from seismic sections, leading to a better understanding of the distribution of the porous and permeable bodies. The attributes are also used to detect the impermeable layers. The methodology is based on laboratory experiments which have shown that a formation permeability indicator can be obtained via the computation of 4 input data: P-wave frequency and attenuation, porosity and specific surface. The procedure has been firstly conducted in acoustic logging to estimate permeability of porous layers and to detect water inflows [Mari et al. (2011 Phys. Chem. Earth 36, 17, 1438-1449]. In seismic, the processing is performed in order to measure these parameters. The analytic signal is used to compute the instantaneous frequency and attenuation (Q factor. The porosity and specific surface are computed from seismic impedances obtained by acoustic inversion of the migrated seismic sections. The input parameters are used to compute a new index named Ik-Seis factor (Indicator (I of permeability (k from acoustic or seismic (Seis data. The potential of the proposed procedure is demonstrated via a field case, both in full waveform acoustic logging and in seismic surveying. The example shows that the Ik-Seis factor can be used to map both the distribution of the permeable bodies in the carbonate formations and the non permeable shaly layers associated with the Callovo-Oxfordian claystone. Dans le but d’avoir une meilleure comprehension de la distribution des corps poreux et permeables d’une formation geologique, nous montrons que de nouveaux attributs peuvent etre extraits des donnees sismiques. Les attributs peuvent etre egalement utilises pour detecter les niveaux impermeables. La methodologie est basee sur des mesures experimentales effectuees en laboratoire, qui ont montre qu’un indicateur de permeabilite peut etre obtenu a partir de quatre grandeurs

    Matching procedures are often used in reservoir production to improve geological models. In reservoir engineering, history matching leads to update petrophysical parameters in fluid flow simulators to fit the results of the calculations with observed data. In the same line, seismic parameters are inverted to allow the numerical recovery of seismic acquisitions. However, it is well known that these inverse problems are poorly constrained. The idea of this original work is to simultaneous match both the permeability and the acoustic impedance of the reservoir, for an enhancement of the resulting geological model. To do so, both parameters are linked using either observed relations and/or the classic Wyllie (porosity impedance) and Carman-Kozeny (porosity-permeability) relationships. Hence production data are added to the seismic match, and seismic observations are used for the permeability recovery. The work consists in developing numerical prototypes of a 3-D fluid flow simulator and a 3-D seismic acquisition simulator. Then, in implementing the coupled inversion loop of the permeability and the acoustic impedance of the two models. We can hence test our theory on a 3-D realistic case. Comparison of the coupled matching with the two classical ones demonstrates the efficiency of our method. We reduce significantly the number of possible solutions, and then the number of scenarios. In addition to that, the augmentation of information leads to a natural improvement of the obtained models, especially in the spatial localization of the permeability contrasts. The improvement is significant, at the same time in the distribution of the two inverted parameters, and in the rapidity of the operation. This work is an important step in a way of data integration, and leads to a better reservoir characterization. This original algorithm could also be useful in reservoir monitoring, history matching and in optimization of production. This new and original method is patented and contributes to an improvement in History matching, Seismic interpretation, Reservoir characterization and Matching procedures (inverse problems).

    Full Text Available A systematic investigation of wave propagation in random media is presented. Spectral analysis, inversion of codas and attenuation of the direct wave front are studied for synthetic data obtained in isotropic or anisotropic, 2D or 3D media. A coda inversion process is developed and checked on two sets of real data. In both cases, it is possible to compare the correlation lengths obtained by inversion to characteristic lengths measured on seismic logs, for the full scale seismic survey, or on a thin section, for the laboratory experiment. These two experiments prove the feasibility and the efficiency of the statistical inversion of codas. Correct characteristic lengths can be obtained which cannot be determined by another method. Le problème de la géophysique est la recherche d'informations concernant le sous-sol, dans des signaux sismiques enregistrés en surface ou dans des puits. Ces informations sont habituellement recherchées sous forme déterministe, c'est-à-dire sous la forme de la donnée en chaque point d'une valeur du paramètre étudié. Notre point de vue est différent puisque notre objectif est de déduire certaines propriétés statistiques du milieu, supposé hétérogène, à partir des sismogrammes enregistrés après propagation. Il apparaît alors deux moyens de remplir l'objectif fixé. Le premier est l'analyse spectrale des codas ; cette analyse permet de déterminer les tailles moyennes des hétérogénéités du sous-sol. La deuxième possibilité est l'étude de l'atténuation du front direct de l'onde, qui conduit aussi à la connaissance des longueurs caractéristiques du sous-sol ; contrairement à la première méthode, elle ne semble pas pouvoir être transposée efficacement à des cas réels. Dans la première partie, on teste numériquement la proportionnalité entre le facteur de rétrodiffraction, relié aux propriétés statistiques du milieu, et le spectre des codas.

    Integration of data different sources and nature leads to more accurate reservoir models, useful for controlling fluid and assessing final uncertainties. In this frame, this thesis presents a new technique for co-simulating in 3D two high resolution properties - one categorical, one continuous - conditionally to well information and under the constraint of seismic data. This technique could be applied to simulate lithofacies and related reservoir properties like acoustic impedances or porosities. The proposed algorithm combines a non-parametric approach for the categorical variable and a parametric approach for the continuous variable through a sequential co-simulation. The co-simulation process is divided in two steps: in the first step, the lithofacies is co-simulated with the seismic information by a sequential indicator co-simulation with co-kriging and, in the second step, the reservoir property of interest is simulated from the previously co-simulated lithofacies using sequential Gaussian (co- )simulation or P-field simulation. A validation study on a synthetic but realistic model shows that this technique provides alternative models of lithofacies and associated high resolution acoustic impedances consistent with the seismic data. The seismic information constraining the co-simulations contributes to reduce the uncertainties for the lithofacies distribution at the reservoir level. In some case, a Markov co-regionalization model can be used for simplifying the inference and modelling of the cross-covariances; finally, the co-simulation algorithm was applied to a 3D real case study with objective the joint numerical modelling of lithofacies and porosity in a fluvial channel reservoir.

  11. Inversion of seismic data: how to take the correlated nature of noise into account; Inversion de donnees sismiques: prise en compte de la nature correlee du bruit

    Energy Technology Data Exchange (ETDEWEB)

    2003-01-01

    The goal of seismic inversion is to recover an Earth model that best fits some observed data. To reach that goal, we have to minimize an objective function that measures the amplitude of the misfits according to a norm to be chosen in data space. In general, the used norm is the L2 norm. Unfortunately, such a norm is not adapted to data corrupted by correlated noise: the noise is in that case inverted as signal and the inversion results are unacceptable. The goal of this thesis is to obtain satisfactory results to the inverse problem in that situation. For this purpose, we study two inverse problems: reflection tomography and waveform inversion. In reflection tomography, we propose a new formulation of the continuum inverse problem which relies on a H1 norm in data space. This allows us to account for the correlated nature of the noise that corrupts the kinematic information. However, this norm does not give more satisfactory results than the ones obtained with the classical formalism. This is why, for sake of simplicity, we recommend to use this classical formalism. Then we try to understand how to properly sample the kinematic information so as to obtain an accurate approximation of the continuum inverse problem. In waveform inversion, we propose to directly invert data corrupted by some correlated noise. A first idea consists in rejecting the noise in the residues. In that goal, we can use a semi-norm to formulate the inverse problem. This technique gives very good results, except when the data are corrupted by random noise. Thus we propose a second method which consists in retrieving, by solving an inverse problem, the signal and the noise whose sum best fits the data. This technique gives very satisfactory results, even if some random noise pollutes the data, and is moreover solved, thanks to an original algorithm, in a very efficient way. (author)

    Governmental organizations have manifested their need for rapid and precise information in the two main fields covered by operational seismology, i.e.: major earthquake alerts and the detection of nuclear explosions. To satisfy both of these constraints, it is necessary to implement increasingly elaborate automation methods for processing the data. Automatic processing methods are mainly based on the flowing elementary steps: detection of a seismic signal on a recording; identification of the type of wave associated with the signal; linking of the different detected arrivals to the same seismic event; localization of the source, which also determines the characteristics of the event. Otherwise, two main categories of processing may be distinguished: methods suitable for large aperture networks, which are characterized by single-channel treatment for detection and identification, and antenna-type methods which are based on searching for consistent signals on the scale of the net work. Within the two main fields of research mentioned here, our effort has focused on regional-scale seismic waves in relation to large-aperture networks as well as on detection techniques using a mini-network (antenna). We have taken advantage of the extensive set of examples in order to implement an automatic procedure for identifying regional seismic waves on single-channel recordings. With the mini-networks, we have developed a novel method universally applicable and successfully applied to various different types of recording (e.g. seismic, micro-barometric, etc) and networks adapted to different wavelength bands.

  1. Feasibility of Seismic Monitoring at a Potential CO2 Injection Test Site in the Paris Basin Évaluation des apports de la sismique à la surveillance d’un test d’injection de CO2 sur un site pilote potentiel du Bassin de Paris

    Directory of Open Access Journals (Sweden)

    Becquey M.

    2009-09-01

    Full Text Available Seismic effects of the injection of CO2 into a partially depleted oil field have been evaluated. Seismic modelling yields small time-lapse effects, including 0.4 ms time-shifts and 4 to 6% amplitude variations at the top and bottom of the reservoir. Amplitude variations at the reservoir level should be slightly larger at large incidence angles, but wave equation modelling shows that picking these reflections will not be easy, because of the presence of shear waves generated at upper interfaces. In-situ fracturation generates azimuthal anisotropy with velocity and amplitude variations with the propagation direction. These variations bear some information about the crack density, about the relation between the fracture nets and the porous medium, and about the fluid content in the pores and fractures. All these effects are however weak and their measurement requires careful seismic data acquisition and processing. Les effets sismiques de l’injection de dioxyde de carbone dans un gisement de petrole deplete ont fait l’objet d’une simulation. Ces effets sont faibles. On peut s’attendre a une variation des temps d’arrivee des reflexions sur des interfaces situees en dessous des reservoirs, de l’ordre de la demi-milliseconde, et a une variation d’amplitude au toit et au mur du reservoir de l’ordre de 6 %. La variation d’amplitude sera legerement plus forte pour les reflexions a grand deport, mais le pointe des reflexions et la mesure des amplitudes seront probablement plus difficiles, en raison de la presence d’ondes converties. La mesure de l’anisotropie azimutale, due a la presence de fractures, peut nous donner des informations sur l’etat de fracturation du reservoir et sur la connexion entre ces fractures et la matrice poreuse. La mesure de ces variations subtiles necessitera une acquisition soignee et un traitement precautionneux des donnees.

    2011-02-01

    Full Text Available IFP Energies nouvelles, CGGVeritas and GDF Suez have conducted together, since 1980, a series of seismic monitoring experiments in order to detect and follow the movements of the gas plume in natural gas geologic storages. Surface and well seismic surveys were carried out at different stages of the storage life. Permanent receiver arrays have been set down in wells. Permanent sources have been designed. Sources and receivers have been used to follow continuously the storage cycle during several years, providing time measurement accuracy within a tenth of a millisecond. Gas intrusion into an aquifer leads to an increase in the arrival times of reflections beneath the storage reservoir and to a variation of the reflection amplitudes at top and bottom of the reservoirs. Progressive variations of the seismic parameters may be followed during the initial infill period. Further movements of the gas plume with the annual in/out cycles are more difficult to follow, because of the simultaneous presence of gas and water in the pores. Arrival time variations of some tenths of a millisecond may be detected and measured. Saturations, using accurate picking of the arrival times, can be estimated in favourable cases. Because of the higher density of carbon dioxide, when stored in a supercritical phase, sensitivity of the seismic parameters, velocity, density and acoustic impedance to saturation variations will be about twice smaller for CO2 storages than it is for methane. IFP Energies nouvelles, la CGGVeritas et GDF Suez ont mené ensemble, depuis 1980, de nombreuses expériences de monitoring sismique afin de détecter et de suivre les mouvements du gaz dans des stockages géologiques de gaz naturel. Des acquisitions ont été réalisées à différents stades de la vie du stockage tant en sismique de surface qu’en sismique de puits.

    L'énergie la plus importante libérée au niveau de la cro te terrestre par un séisme est sous forme d'ondes superficielles, appelées ondes de Rayleigh. Sous l'effet de ces ondes à déplacements verticaux de forme elliptique, le sol et les bâtiments qu'il soutient vibrent dans une gamme de fréquences de 0,1 à 30 hertz. Cette gamme de valeurs est spécialement nocive pour les bâtiments élancés. Les calculs de dimensionnement des ouvrages de génie civil prennent en compte ce type de sollicitation, via des forces horizontales de remplacement. Les différentes normes nationales définissent une accélération nominale due au séisme, au moyen d'une combinaison de classes d'ouvrages et de zones sismiques. De plus, des mesures spéciales de dispositions constructives et de conception architecturale sont prescrites. Les statistiques montrent que 90% des ouvrages ont été construits avant l'introduction, fin des années 80, des normes de construction parasismiques modernes.

    Full Text Available ROVIM converts migrated zero-offset seismic data into acoustic impedance pV (ROV by inverse modeling (IM. It follows a model-based approach where the model parameters are sparse and constrained. Starting with a simple macromodel, the program is able to produce a broad-band impedance micromodel by iteratively updating a multichannel impedance model. The resulting impedance model may be validated by comparison to well logs, since these are not input explicitly into the program. In this article, we present our workshop results. We show how important the constraints applied to the model parameters are for tackling the imperfection of the real seismic data and the non-uniqueness of the data-related solutions. ROVIM est un programme informatique de modeling inverse qui transforme des données sismiques à offset nul et migrées en impédance acoustique. Il est caractérisé par l'utilisation d'un modèle initial généralement simple qui est décrit par des paramètres (temps de réflexion et impédance contraints et représentatifs de la stratigraphie présente. A partir des données entrées à l'aide d'un macro-modèle, le programme calcule itérativement un micro-modèle d'impédance, lissé latéralement mais pas verticalement, de façon à réduire les résidus entre les données réelles et la réponse du modèle. Le micro-modèle d'impédance obtenu peut être validé ponctuellement par les logs d'impédance déduits des diagraphies, car ceux-ci ne sont pas entrés dans le programme. Dans cet article, nous présentons la méthode ROVIM, ainsi que nos résultats du Workshop inversion stratigraphique. Nous montrons l'importance de l'optimisation des paramètres du modèle sous contrainte, afin de prendre en compte la non-unicité des solutions issues des données sismiques, ainsi que l'imperfection des données sismiques inversées.

  10. Introduction of a priori information in the elastic linearized inversion of seismic data before stacking; Introduction d'informations a priori dans l'inversion linearisee elastique de donnees sismiques de surface avant sommation

    In this thesis, we propose a method which takes into account a priori information (geological, diagraphic and stratigraphic knowledge) in linearized pre-stack seismic data inversion. The approach is based on a formalism in which the a priori information is incorporated in an a priori model of elastic parameters - density, P and S impedances - and a model covariance operator which describes the uncertainties in the model. The first part of the thesis is dedicated to the study of this covariance operator and to the norm associated to its inverse. We have generalized the exponential covariance operator in order to describe the uncertainties in the a priori model elastic parameters and their correlations at each location. We give the analytical expression of the covariance operator inverse in 1-D, 2-D, and 3-D, and we discretized the associated norm with a finite element method. The second part is dedicated to synthetic and real examples. In a preliminary step, we have developed a pre-stack data well calibration method which allows the estimation of the source signal. The impact of different a priori information is then demonstrated on synthetic and real data. (author)

    Full Text Available O trabalho analisa a reorganização espacial de três redes bancárias privadas - Bradesco, Bamerindus (atual HSBC e Unibanco - que surgem na primeira metade do século XX em São Paulo, Paraná e Minas Gerais. Como evoluíram essas redes bancárias? Como interagiram com outros processos que moldam sua extensão territorial e social? O artigo examina os condicionantes externos e internos que mudaram a trajetória do sistema bancário no Brasil e apresenta um conjunto de mapas que mostram a localização das redes de agências desses bancos e suas mudanças locacionais (1986-1996 e 1996-2005. O texto conclui que a reorganização resultou da combinação de processos adaptativos e inovativos que demandaram uma nova geografia ajustada às condições macro e microeconômicas emergentes. Nesse processo os bancos inventaram ou reinventaram o correspondente bancário, objeto híbrido que combina serviço, tecnologia de comunicação e produto, viabilizando uma expansão territorial e social sem precedentes no território brasileiro.

    1996-01-01

    Full Text Available Les Andes Nord équatoriennes ont connu de nombreux séismes historiques destructeurs. Pour caractériser l’aléa sismique de la région andine, nous avons fait une révision critique de la sismicité historique et de l’ensemble des failles actives de l’Équateur. Les deux sources majeures de l’aléa sismique sont respectivement la subduction superficielle pour la région côtière et le système transpressif des hautes Andes pour la région andine. Ce système est composé de failles décrochantes dextres d’orientation N30-35°E (failles du Rio Chingual-La Sofia et Pallatanga qui limitent respectivement au Nord et au Sud des failles inverses N-S du relais compressif de la vallée interandine (failles de Quito et de Latacunga. L’étude des mécanismes au foyer superficiels des Andes équatoriennes nous a permis de calculer une vitesse de raccourcissement crustal de 4.6 mm/a selon une direction N92°E et d’estimer des temps de récurrence et des périodes de retour. Un séisme de Mw = 5 pourrait se produire tous les 0.5 an, de Mw = 6 tous les 4.5 ans, de Mw = 7 tous les 45.4 ans. De même, sur une période de temps de 33 ans, 66 séismes de Mw=5 peuvent être attendus, 7 séismes de Mw=6 et 1 séisme de Mw=7. Enfin, nous avons estimé pour l’ensemble des sources sismogènes de la région andine des magnitudes maximales probables et des temps de récurrence. Un séisme de magnitude 7 à 7.5 peut se produire sur la faille du Rio Chingual tous les 400±440 ans et de magnitude 6.7 à 7.2 tous les 380±320 ans sur la faille de Pallatanga. Dans la vallée interandine, la faille de Quito est susceptible d’engendrer un séisme de magnitude 6.6 à 7.6 tous les 930±300 ans. LA AMENAZA SÍSMICA EN LOS ANDES ECUATORIANOS.

    Full Text Available O presente artigo tem por objetivo apresentar um modelo geral de firma bancária que incorpore a teoria pós-keynesiana da preferência pela liquidez dos bancos, a hipótese Stiglitz-Weiss de que a taxa de inadimplência dos devedores é uma função crescente da taxa de juros e a hipótese tobiniana de que a proporção dos depósitos que o banco consegue reter é uma função crescente do grau de concentração do setor bancário. Esse modelo geral nos permite obter três conclusões importantes. Em primeiro lugar, demonstra-se que o spread bancário ótimo é uma função crescente do grau de concentração do setor bancário. Em se-gundo lugar, demonstra-se que um aumento da taxa básica de juros irá resultar (i numa redução do spread bancário ótimo e (ii numa redução do volume de crédito ofertado pelo banco. Por fim, demonstra-se que um aumento do grau de concentração tem um efeito ambíguo sobre a oferta de crédito bancário.The objective of the present article is to present a general model of the banking firm beha-vior which encompasses the post Keynesian theory of bank's liquidity preference, the Stiglitz-Weiss´s hypothesis that expected default rate is an increasing function of loan interest rate and the Tobinisque hypothesis that the deposit retention coefficient is an increasing function of the concentration ratio in banking industry. This general model allows us to arrive at some interesting conclusions. First of all, we show that the optimal banking spread is an increasing function of the concentration ratio in banking industry. Second, we show that an increase in the level of the interest rate controlled by the Central Bank will (i reduce the optimal level of the banking spread, and (ii will reduce de supply of banking credit. Last, but not least, we show that an increase in the concentration ratio in banking industry has an ambiguous effect over the supply of banking credit.

    Dolomitization has long been one of the most studied geological processes because of its economic interest (dolomitic rocks form a significant share of hydrocarbon reservoirs) as well as its academic interest, based on the fact that dolomite scarcely forms in current and recent marine environments whereas seawater is highly over-saturated; and that it is still not possible to synthesize it in laboratory under the same conditions. We used data collected by the University of Miami (Bahamas Drilling Project, ODP Leg 166) to understand the geological context of complete dolomitization of a Messinian 60 m thick reef unit. Classical methods of petrographic analysis of thin sections (optical microscopy, cathodoluminescence, scanning electron microscopy, in situ isotopic analyze using ionic microprobe) showed that the intensity of dolomitization is not controlled by the initial texture of the sediment, that the key parameter for dolomitization is the conservation of the initial mineralogy of magnesian bio-clasts, and that redox conditions, salinity and/or temperature of the precipitation fluid varied significantly during the process. Hydrodynamic modelling showed that during periods of high sea-level, Kohout thermal convection is a viable mechanism for driving marine fluids through the sediments. The key parameter for fluid circulations is the permeability anisotropy on the platform scale. Geochemical modelling showed that seawater is able to induce a complete dolomitization over durations of around one million years. Sensitivity tests showed that the critical parameter (as well as one of the less well-known) to describe diagenetic processes in carbonates is the water/rock reactions kinetics and in particular the precipitation kinetics of carbonate minerals. We finally propose that the dolomitization of the reef unit of the Unda well took place during the high sea-level period which extended over 1,1 My in the early Pliocene, according to the Kohout thermal convection model.

    The defence to obtain the 'Habilitation a Diriger des Recherches' is a synthesis of the research work performed since the end of my Ph D. thesis in 1997. This synthesis covers the two years as post doctoral researcher at the Bureau d'Evaluation des Risques Sismiques at the Institut de Protection (BERSSIN), and the seven consecutive years as seismologist and head of the BERSSIN team. This work and the research project are presented in the framework of the seismic risk topic, and particularly with respect to the seismic hazard assessment. Seismic risk combines seismic hazard and vulnerability. Vulnerability combines the strength of building structures and the human and economical consequences in case of structural failure. Seismic hazard is usually defined in terms of plausible seismic motion (soil acceleration or velocity) in a site for a given time period. Either for the regulatory context or the structural specificity (conventional structure or high risk construction), seismic hazard assessment needs: to identify and locate the seismic sources (zones or faults), to characterize their activity, to evaluate the seismic motion to which the structure has to resist (including the site effects). I specialized in the field of numerical strong-motion prediction using high frequency seismic sources modelling and forming part of the IRSN allowed me to rapidly working on the different tasks of seismic hazard assessment. Thanks to the expertise practice and the participation to the regulation evolution (nuclear power plants, conventional and chemical structures), I have been able to work on empirical strong-motion prediction, including site effects. Specific questions related to the interface between seismologists and structural engineers are also presented, especially the quantification of uncertainties. This is part of the research work initiated to improve the selection of the input ground motion in designing or verifying the stability of structures. (author)

Le filtrage matriciel est effectué dans le domaine fréquentiel en utilisant la matrice spectrale construite à l'aide des intercorrélations des différents enregistrements constituant les données à traiter. Les méthodes d'estimation de la matrice spectrale sont des méthodes de moyenne : moyenne en fréquence (méthode du périodogramme lissé et/ou moyenne en distance (lissage réalisé le long des diagonales de la matrice spectrale. Le lissage en fréquence est obtenu par l'intermédiaire d'une fonction de pondération (par exemple fenêtre de Hanning élevée à une puissance donnée appliquée à chaque corrélation. Les moyennes sont utilisées pour décorréler les signaux et de ce fait favoriser la séparation. Une fois correctement estimée, la matrice spectrale est diagonalisée sur toutes les fréquences du spectre moyenné, et décomposée selon ses vecteurs propres qui sont orthogonaux entre eux et normalisés. Chaque vecteur propre a une valeur propre associée qui représente la répartition d'énergie en fonction de la fréquence du modèle lié au vecteur propre.

    Wolff, Wim J.; Michaelis, Hermann

    2008-09-01

    The 500 km 2 of tidal flats at the Banc d'Arguin, Mauritania, are a wintering site for over 2 million shorebirds, making this one of the areas with the highest density of shorebirds in the world. In earlier studies, it was found that these huge numbers of birds are dependent on a rather low biomass of benthic animals. To explain this paradoxical situation, we hypothesized that the earlier assessments of biomass in late winter and early spring do not reflect a year-round situation. Benthic biomass may be high when the birds arrive in autumn to be subsequently grazed down in the course of winter. To test this hypothesis, we have determined benthic biomass in September 1988. The result has been compared with a biomass value obtained in February-April 1986 with the same methods and at the same stations. These two biomass values do not differ significantly; so our hypothesis has to be rejected. It has to be admitted, however, that our experimental design cannot discern between differences due to the year of sampling and those due to the season.

  15. Assessing the contribution of marine protected areas to the trophic functioning of ecosystems: a model for the Banc d'Arguin and the Mauritanian shelf.

    Directory of Open Access Journals (Sweden)

    Sylvie Guénette

    Full Text Available Most modelling studies addressed the effectiveness of marine protected areas (MPA for fisheries sustainability through single species approach. Only a few models analysed the potential benefits of MPAs at the ecosystem level, estimating the potential export of fish biomass from the reserve or analysing the trophic relationships between organisms inside and outside the MPA. Here, we propose to use food web models to assess the contribution of a MPA to the trophic functioning of a larger ecosystem. This approach is applied to the Banc d'Arguin National Park, a large MPA located on the Mauritanian shelf. The ecosystem was modeled using Ecopath with Ecosim, a model that accounts for fisheries, food web structure, and some aspects of the spatial distribution of species, for the period 1991-2006. Gaps in knowledge and uncertainty were taken into account by building three different models. Results showed that the Banc d'Arguin contributes about 9 to 13% to the total consumption, is supporting about 23% of the total production and 18% of the total catch of the Mauritanian shelf ecosystem, and up to 50% for coastal fish. Of the 29 exploited groups, 15 depend on the Banc for more than 30% of their direct or indirect consumptions. Between 1991 and 2006, the fishing pressure increased leading to a decrease in biomass and the catch of high trophic levels, confirming their overall overexploitation. Ecosim simulations showed that adding a new fleet in the Banc d'Arguin would have large impacts on the species with a high reliance on the Banc for food, resulting in a 23% decrease in the current outside MPA catches. We conclude on the usefulness of food web models to assess MPAs contribution to larger ecosystem functioning.

  16. Determinantes macroeconômicos e o papel das expectativas: uma análise do spread bancário no Brasil (2003-2011

    Directory of Open Access Journals (Sweden)

    Tarciso Gouveia da Silva

    Full Text Available Resumo A teoria econômica reconhece a importância das expectativas para a tomada de decisão dos agentes econômicos em um ambiente dinâmico sem previsibilidade perfeita. Apesar de relativamente extensa, a literatura sobre spread bancário no Brasil trata desta questão apenas de forma superficial, não incluindo variáveis macroeconômicas expectacionais. Estas expectativas, que podem afetar as estratégias da firma bancária no processo de maximização de sua rentabilidade, são rotineiramente coletadas e divulgadas pela autoridade monetária e de regulação bancária brasileira e por outras entidades. Incorporamos estas variáveis em um modelo empírico dinâmico de determinação do spread bancário específico de cada banco, seguindo a abordagem de Maudos e Solís (2009. Os dados são trimestrais e a amostra vai de 2003 a 2011. Os resultados corroboram a hipótese aqui proposta de que as variáveis macroeconômicas expectacionais, como a inflação esperada e os juros futuros, são relevantes na determinação do spread bancário no Brasil, mesmo condicional a seus valores correntes.

    Full Text Available

    Les targetes bancàries, de crèdit i de dèbit, han constitu¨t tradicionalment l'objecte central dels atacs no violents a patrimonis de les entitats bancàries i dels seus clients, a partir de la utilització de tecnologies basades en el desenvolupament de la informàtica i de les telecomunicacions. Si bé altres fraus i atacs patrimonials s'han sumat a aquestes pràctiques, el frau de targetes continua constituint una realitat criminològica de primer ordre.

    La resposta del dret penal a aquestes pràctiques ha anat mantenint una notable falta de sistemàtica, que en certa manera ha estat substitu¨da per l'actuació dels tribunals, els quals han anat distribuint la variada fenomenologia delictiva en els diferents tipus penals en els quals han encaixat millor. L'absència d'un delicte de frau amb targetes, la possibilitat d'actuar il·lícitament amb targetes reals o de confecció falsa, l'ús d'aquestes en caixers automàtics, en comerços o la seva numeració per Internet dificulten notablement la qualificació jurídica de les conductes. Els tribunals han anat aplicant els delictes de robatori amb força, estafa i estafa informàtica segons l'execució concreta de la conducta delictiva derivada de l'ús il·lícit de la targeta, si bé la voluntat de reduir al màxim els espais d'impunitat ha portat en algunes resolucions judicials a forçar la interpretació dels tipus penals més enllà de l'exigible.

    A això cal sumar-hi el tractament incongruent que el legislador ha donat a la falsificació de targetes bancàries, assimilant-la de forma genèrica a la falsificació de moneda, provocant una interpretació novament extensiva del Tribunal Suprem i assignant-li una penalitat sens dubte desorbitada.

    El recurs al principi de legalitat i al de protecció exclusiva de béns jurídics s'imposa en una matèria normativament confusa i amb un tractament judicial erràtic.

  20. Falência Bancária e Capital Regulatório: Evidência para o Brasil

    Directory of Open Access Journals (Sweden)

    Marcelo Liberman

    Full Text Available O objetivo deste artigo é avaliar empíricamente em que medida o nível de capital sobre os ativos ponderados pelo risco, o Índice de Basileia, é capaz de prevenir a falência de instituições financeiras. Adicionalmente, compara-se o desempenho desse indicador nessa tarefa com o do índice simples de capitalização, sem a ponderação pelo risco dos ativos. Um dos desafios para a realização de estudos dessa natureza no Brasil é que o Índice de Basileia reportado para cada instituição está disponível publicamente apenas a partir de 2009, ao passo que grande parte das falências bancárias ocorreu no período entre 1995 e 2005. A partir dos balanços e demonstrações de resultados de 313 instituições financeiras brasileiras, e de resoluções do Conselho Monetário Nacional (CMN e circulares do Banco Central (BACEN sobre regulação bancária no Brasil, construiu-se um Índice de Basileia Sintético (IBS para cada uma das instituições analisadas para o período de dezembro de 1995 a dezembro de 2014. A partir do IBS, avaliou-se se (e em que magnitude um nível mais alto de capital em relação aos ativos de risco diminui a probabilidade de falência da instituição. Utilizando modelos logit, estimou-se que aumento de um ponto percentual no IBS aumenta em 1,04 vezes a chance de uma instituição financeira não falir. Uma análise do tipo survival mostra que um aumento de um ponto percentual no IBS atrasa a falência de uma instituição financeira em 1,08 vezes. O IBS tem um desempenho superior ao do índice de capitalização simples na previsão de falências. Os resultados obtidos corroboram a hipótese de uma relação inversa entre nível de exigências de capital sobre ativos ponderados pelo risco e a probabilidade de falência bancária.

    Full Text Available Introdução: Estresse ocupacional é considerado fator de risco para o diabetes mellitus. Bancários são submetidos constantemente ao estresse, podendo alterar os níveis glicêmicos e lipêmicos. Objetivo: analisar as alterações nos níveis de glicemia e associa-las ao estresse ocupacional em bancários. Materiais e Métodos: Trata-se de pesquisa descritiva e analítica. Avaliou-se glicemia de jejum capilar, aferição da medida da pressão arterial, peso, altura, circunferência abdominal, cálculo do Índice de Massa Corpórea, aplicação de questionários de perfil diabético e de teste de Inventário de Sintomas de Stress de Lipp, para as análises das fases de estresse. Resultados: Foram16 voluntários, 12 homens, com idade média de 34,92 ± 3,14 anos e 4 mulheres, 30,25 ± 2,63 anos. Entre os homens, 91,60% apresentaram glicemia de jejum alterada (115,71±2,01mg/dl, 41,60% com sobrepeso (28,04±0,26kg/m2 e 16,88% com obesidade (32,35±0,65kg/m2. 58,33% dos homens estavam com estresse, sendo que 85,71% desses homens estavam na fase de resistência e 14,28% na fase de exaustão. Nas mulheres, 75% apresentaram glicemia de jejum alterada (126,44±5,49mg/dl, 25% tinham sobrepeso (26,93±0,13kg/m2 e 25% obesidade (32,30 kg/m². Na avaliação do estresse foram encontrados 75% das mulheres com estresse, estando todas na fase de resistência. Discussão: São necessárias intervenções no ambiente de trabalho que propicia um processo de adoecimento. Conclusões: Bancários que se encontravam em alguma fase de estresse, apresentavam níveis glicêmicos alterados, sinalizando uma possível ação do cortisol em sua rotina diária.

    Full Text Available Apesar dos diversos estudos que se desenvolveram nos últimos anos enfocando o crescimento dos chamados correspondentes bancários (CBs como canal de distribuição de serviços financeiros à população de baixa renda no Brasil, existe uma importante lacuna nessa literatura, relacionada à compreensão das diferentes formas pelas quais redes de CBs podem ser montadas e geridas. No presente artigo teve-se por objetivo construir um mapeamento das diferentes configurações de negócios - ou modelos de gestão de redes de CBs - hoje praticadas na utilização do canal de CBs pelos bancos brasileiros. Para tanto, adotou-se um método taxonômico, que permitiu distinguir a existência de seis diferentes modelos de gestão de redes de CBs praticados pelos bancos na gestão do canal, os quais foram, por sua vez, agrupados em três classes, de acordo com o grau de delegação de atividades a gestores de rede terceirizados. O resultado do trabalho é um mapeamento inédito das diferentes configurações de negócios praticadas na operação do canal de CBs no Brasil. A relevância da contribuição deriva da escassez de referências ao tópico em estudos anteriores, bem como da importância adquirida em anos recentes pelo canal de CBs como um dos principais canais de distribuição de serviços bancários à população de baixa renda.

    S-wave polarized in the coordinate planes. The nearly exhaustive collection of experimental data on seismic anisotropy in rocks (considered as transverse isotropic by Thomsen (1986 show that elliptical anisotropy is more an exception than a rule. Since stress-induced anisotropy is essentially elliptical when restricted to transversely isotropic media, as a consequence this work clearly shows that stress can be practically excluded as a unique direct cause of elastic anisotropy in rocks. Ce résumé contient des formules (*** qui ne peuvent s'afficher à l'écran Un principe général esquissé par P.

Par exemple, en ce qui concerne l'anisotropie sismique induite par les contraintes, la symétrie la plus complexe présentée par un milieu initialement isotrope, sous contrainte triaxiale, est orthorhombique ou orthotrope, caractérisée par trois plans de symétrie orthogonaux deux à deux (Nur, 1971. À d'autres égards, Schwartz et al.

La question posée est la suivante : est-ce que ce résultat est vrai pour tous les modèles de roches ? et, plus généralement, est-ce que les roches initialement isotropes, quand elles sont soumises à une contrainte triaxiale, forment un sous-ensemble bien défini des milieux orthorhombiques ?

MÉTODO: Estudo seccional de amostra aleatória simples de 647 funcionários, através de questionário auto-respondido no ambiente de trabalho. RESULTADOS: A prevalência de tabagismo foi de 29,5% (Intervalo de Confiança (IC 95%: 27,5% a 31,5%, sendo 31,1% (IC 95%: 26,2% a 35,8% entre homens e 27,8% (IC 95%: 22,6% a 32,9% entre mulheres. O início do hábito ocorreu, em média, aos 17,6 anos entre os homens e 19,4 anos entre as mulheres. Observou-se alta prevalência de grandes fumantes entre homens e mulheres (53% e 42% respectivamente fumavam mais de 20 cigarros por dia. A freqüência de tabagismo foi maior nos mais velhos, nos divorciados separados e viúvos, nos hipertensos, naqueles que consumiam mais bebidas alcoólicas, e nos que não praticavam exercícios físicos. Comparados aos não-fumantes, os ex-fumantes eram mais velhos, consumiam mais bebidas alcoólicas e apresentavam maior freqüência de sobrepeso.

La démarche s’appuie sur une surface de réponse obtenue à partir de calculs pushover du bâtiment. L’analyse pushover a été effectuée sous le logiciel ZeusNL. Une étude de cas a été réalisée sur un bâtiment type en utilisant un plan d’expérience factoriel complet construit sur les trois paramètres de conception comprenant la résistance caractéristique du béton, la section moyenne de béton des poteaux et poutres et leurs armatures longitudinales. L’analyse de variance effectuée sur les résultats obtenus a permis de déterminer l’effet de chaque paramètre sur la performance sismique du bâtiment. Les résultats ont montré que la section moyenne des coffrages et leurs ferraillages contrôlent de manière prépondérante la capacité sismique du bâtiment vis-à-vis des états limites considérés. L’optimisation de la réhabilitation sismique a été alors proposée. In this work, a simplified methodology was proposed in order to evaluate seismic vulnerability of reinforced concrete buildings. The approach is founded on response surface obtained through pushover calculations of the building. Pushover analysis was performed under ZeusNL software. A case study was carried out on a typical building by using full factorial design of experiment table constructed on the three design parameters that include concrete resistance, the average concrete section of beams and columns and their longitudinal reinforcements. Analysis of variance performed on the obtained results enabled determining the effect of each parameter on seismic performance of the building. It was shown that concrete average section and reinforcements control preponderantly seismic capacity of the building with regards to the considered limit states. Optimisation of seismic rehabilitation was then proposed.

    Full Text Available The challenge of seismic exploration in fold and thrust belt settings is to optimize the depth seismic images of the deep structural objectives beneath a complex overburden that may show strong horizontal and vertical velocity variations. In such areas, the seismic image is frequently of poor quality and the depth models of deep layers is often false due to the perturbed propagation of seismic energy through the deforming lens of the overlying layers. A range of seismic processing tools, including post-stack and pre-stack depth migrations, are appropriate to predict the accurate geometry of deep target structures and to improve the building of a depth structural model. A strong combination of geological reasoning and depth seismic imaging processing can improve the understanding of the deep geological structures by reducing the uncertainties in depth geometrical and velocity model estimation. We propose an interpretative and iterative approach to the post stack depth migration method to guide the interpreter in the development of a reliable subsurface model. We have applied this approach during an exploration study in the Dumre area, located in the Ionian Basin (Albania which is a complex fold and thrust belt. The main objectives of this study were to understand the failure of a former exploration well and to propose a new location for the potential closure of the carbonate structure. This subsalt imaging study aims at illustrating the improvements obtained by application of this integrated seismic imaging method especially in the evaluation of a subthrust prospect in a tectonically complex belt setting. Le challenge de l’exploration pétrolière par la sismique réflexion dans les zones de montagne est d’obtenir des coupes capables de bien imager les structures géologiques profondes situées sous une couverture sédimentaire plissée. Cette série de sédiments peut être très complexe et engendrer ainsi de fortes variations latérales et

    Full Text Available Este estudo empírico-analítico tem por objetivos promover uma comparação dos níveis de regulação da atividade de auditoria em instituições bancárias e avaliar a relação entre esse grau de regulação e características dos sistemas bancários nacionais. Utilizou-se uma base de dados mantida pelo Banco Mundial, contendo pesquisa realizada junto a autoridades supervisoras e regulatórias bancárias nacionais de 172 países. Por meio de estatísticas descritivas, foi constatado que o nível mais elevado de regulação é registrado nas nações mais desenvolvidas e nos países do Oriente Médio, Norte da África, Europa e Ásia Central. Também foi constatado que o Brasil apresenta grau de regulação superior à média verificada internacionalmente. Quanto aos testes realizados, por meio de regressão, para avaliar a relação entre o nível de regulação de auditoria e características do setor bancário, foi evidenciado que há mais requerimentos para a atuação dos auditores nos países em que o crédito doméstico provido pelo setor bancário é maior e onde os bancos são mais rentáveis. Por outro lado, há menor regulação nos países em que há maior participação de bancos estatais no sistema financeiro e onde há mais restrições à atuação das instituições bancárias. Não foi confirmada a hipótese de associação positiva entre grau de concentração do setor bancário e o nível de regulação da atividade de auditoria. Por fim, foi constatado que, em 2000, primeiro ano da pesquisa, o nível de regulação era menor que os níveis apurados nos demais exercícios, enquanto que, em 2007, último ano da pesquisa, o nível de regulação é maior que nos anos anteriores, confirmando o que foi encontrado na literatura de que as normas de auditoria tendem a se tornar mais rigorosas com o passar do tempo, na medida em que a demanda por requerimentos mais estritos se acumula, notadamente em momentos de crise de

Second, the model was constrained to production data and 4D seismic attributes, applying gradual deformation to facies realizations and varying facies proportions. The integration of 4D seismic data led to better production forecasts and improved predictions confirmed by a new seismic survey shot two years after the history matching period. 4D seismic data also contributed to better characterize the spatial distribution of heterogeneities in the field. As a result, the fine scale geological model was improved consistently with respect to the fluid flow simulation model and the observed data. The Girassol study, already presented in (Roggero et al., 2007, 2008, has been updated with recent information and a more detailed presentation concerning the construction of the geological model based on 3D seismic data.

    Full Text Available Facing an international financial crisis that could lead its own financial system to the brink of collapse, the German government needed to show political will in order to save financial institutions in risky situations. This article analyzes the legal strategies used to rescue the financial system, including the statization of banking institutions as an ultima ratio. Prior to the bank statization established by the Rescue Takeover Act, the Financial Market Stabilization Act foresaw an increase in the capital of financial institutions by means of state control without statization. This last act, nonetheless, has not been considered enough to avoid the collapse of a banking institution that is relevant for the whole financial system such as Hypo Real Estate (HRE.Enfrentando uma crise financeira internacional que pode levar ao colapso de seu próprio sistema financeiro, o governo alemão precisou demonstrar vontade política para salvar instituições financeiras em situação de risco. Este artigo analisa as estratégias legais utilizadas no resgate do sistema financeiro, incluindo a estatização de instituições bancárias como ultima ratio. Antes da lei de estatização bancária, da Lei de Resgate de Empresas para a Estabilização do Mercado Financeiro, a Lei de Estabilização do Mercado Financeiro previa um aumento do capital das instituições financeiras com controle estatal sem estatização. Esta lei, no entanto, não foi considerada suficiente para evitar o colapso de uma instituição bancária relevante para todo o sistema financeiro como o Hypo Real Estate (HRE.

    Full Text Available OBJETIVO: Estimar a prevalência de casos sugestivos de LER/DORT e fatores associados três décadas após a reestruturação bancária. MÉTODOS: Estudo transversal com 356 funcionários de 27 agências bancárias das redes pública e privada de Porto Alegre, RS, entre abril e agosto de 2009. Foi utilizada análise estatística bruta e ajustada pelo modelo de Regressão de Poisson com variância robusta, conduzida por modelo hierárquico em três níveis, incorporando-se a estrutura do delineamento e ajuste para os conglomerados. Os resultados foram estratificados por porte da agência e dicotomizados (≥ 25 e < 25 funcionários. RESULTADOS: A prevalência de casos sugestivos de LER/DORT foi menor nos homens (RP = 0,62 IC95% 0,47;0,81. Trabalhadores com idade entre 26 e 45 anos (RP = 2,51 IC95% 1,02;6,14 apresentaram maior prevalência do desfecho. Indivíduos com pós-graduação (RP = 0,45 IC95% 0,22;0,90 e tempo na função entre 5,1 e 15 anos (RP = 0,62 IC95% 0,47;0,81 apresentaram fator de proteção para os casos sugestivos de LER/DORT. Ao estratificar as análises por porte, nas agências com 25 funcionários ou menos, idade, renda e tempo na função permaneceram associados, enquanto nas agências com mais de 25 funcionários, sexo e escolaridade associaram-se ao desfecho. CONCLUSÕES: Aspectos importantes no adoecimento por LER/DORT entre bancários parecem hoje ser diferentes dos historicamente conhecidos. Atenção maior à organização do trabalho e às estratégias de gestão deveria ser considerada na elaboração de programas de prevenção de adoecimento no trabalho bancário.

    Full Text Available Using the paradigmatic example of Catalunya Banc, this paper analyses the Spanish varieties of the new financial engineering used to appropriate urban rent by home dispossession. It aims to contribute to the study of the new forms of financialization that have appeared since 2008. Particular attention is given to the role of the state, the emergence of private equity funds as global real estate owners and how this has translated into a wave of evictions due to mortgage foreclosures. In short, this article highlights the implications of the uneven development resulting from the exhaustion of the so-called Spanish model of accumulation during the real estate boom years.

    This thesis intends to characterize ground motion during earthquake. This work is based on two Japanese networks. It deals with databases of shallow events, depth less than 25 km, with magnitude between 4.0 and 7.3. The analysis of K-net allows to compute a spectral ground motion prediction equation and to review the shape of the Eurocode 8 design spectra. We show the larger amplification at short period for Japanese data and bring in light the soil amplification that takes place at large period. In addition, we develop a new empirical model for simulating synthetic stochastic nonstationary acceleration time histories. By specifying magnitude, distance and site effect, this model allows to produce many time histories, that a seismic event is liable to produce at the place of interest. Furthermore, the study of near-field borehole records of the Kik-net allows to explore the validity domain of predictive equations and to explain what occurs by extrapolating ground motion predictions. Finally, we show that nonlinearity reduces the dispersion of ground motion at the surface. (author)

    The Rayda Basin, located in northern Oman at the south-eastern passive margin of the Arabian plate, has been filled in by a pro-grading carbonate system during the Lower Cretaceous. The filling up basin realized to carbonate platform pro-gradation on 300 km. Pelagic facies represented with radiolarian chert and shallowing facies with erosive surface, mud-cracks and lagoonal mud, and displaying on seismic lines an alternation of high angle and low angle clinoforms at the 10's of kilometers scale. Detailed study of these two types of clinoforms in the nearby outcrops shows that the high angle system is dominated by high-energy, grainy facies (ooliths, rudists, stromatoporoids), while the low angle system is dominated by a low-energy, carbonate mud facies. Based on the subsurface (geometries) and outcrop (facies) data a regional depositional model is proposed for this system. The outcrop study is based on 14 measured sections (6764 meters), completed with photo panoramas, thin section analysis and geochemical analyses (carbonate and organic matter content). The subsurface dataset consists of several regional seismic lines, two high resolution 3D blocs, and is supported by core material The regional seismic lines allow to map out the position of the high and low angle clinoform belts. One high angle belt and two low angle belts are identified in the profiles. In outcrop at least one more high angle belt and one more low angle belt are present. These overall geometries probably define the large scale sequence organisation. At a smaller scale, the 3D blocs allow to show the detailed geometrical organisation of the clinoform belts. The outcrop sections provide critical sub-seismic scale data on the facies composition and depositional geometries. The high energy system of the steep clinoforms (angle estimated at several degrees), is probably a wave controlled barrier coastline system, while the muddy low angle clinoforms (angle < 0.5 degree) shows large convex and wide channeling features, rather suggesting a muddy turbidite system deposited below storm wave base. Regional correlations are established for the outcrop sections, using para-sequence stacking patterns and well expressed bedding patterns, and for the subsurface, combining seismic, core material and wire-line logs. The combination of seismic geometries and sub-seismic scale outcrop shows thus a clear relationship between depositional processes, geometries and facies. (author)

Possible trends between these attributes and the modelled reservoir/geomechanical properties (lithofacies, pressure, temperature, steam saturation, etc. are also evaluated. Finally, geobodies are extracted from the seismic attributes. L’objectif de cette étude est d’évaluer quelle information de production peut être déduite d’une campagne sismique 4D durant le procédé de récupération par injection de vapeur SAGD (Steam- Assisted Gravity Drainage. En plus des hétérogénéités réservoir d’origine géologique, de nombreux facteurs interagissent pendant la production thermique d’huile lourde et de bitume, ce qui complique l’interprétation des données sismiques 4D : variation de la viscosité de l’huile, des saturations en fluide, de la pression de pore, etc. Cette étude est basée sur le champ pétrolier Hangingstone de la formation McMurray en Athabasca (Canada. Dans des travaux antérieurs, un modèle statique initial (géologique, pétroacoustique et géomécanique avait été construit. Puis la production thermique d’huile lourde avait été simulée en mettant en oeuvre le couplage d’un modèle d’écoulement de réservoir et d’un modèle géomécanique. Les paramètres sismiques des roches saturées (densité, vitesses de compression et de cisaillement avaient alors été calculés à plusieurs étapes de la production à partir des paramètres mécaniques et de réservoir. À partir de ces résultats, une acquisition sismique est simulée à quatre états de production SAGD. Comme on s’intéresse aux réflexions sismiques en ondes de compression générées dans le réservoir, une modélisation sismique orientée cible est choisie. Cette modélisation est basée sur une approche ray+Born et permet de calculer la réponse sismique en estimant correctement les amplitudes sismiques en

    Full Text Available Esta pesquisa investiga se a adoção de práticas contábeis conservadoras leva à redução no custo do crédito bancário das empresas no Brasil. O estudo se baseia em uma amostra de 1.300 empresas e de 813 mil contratos de crédito, no período de 2000 a 2009. São utilizados modelos que associam o custo do crédito a medidas de conservadorismo e a um conjunto de variáveis de controle. Não foram obtidas evidências de relação estatisticamente significante entre as medidas de conservadorismo e as taxas de juros das operações crédito, confirmandose a hipótese de pesquisa. O ambiente institucional brasileiro de fraca proteção legal dos credores e de baixa demanda por qualidade da informação contábil restringe os benefícios gerados pelo conservadorismo e faz com que os credores não estimulem a adoção de práticas conservadoras pelas empresas, por meio da redução nas taxas de juros. Como as empresas não percebem benefícios associados ao reporte de números conservadores, a utilização de tais práticas é restrita no Brasil.

    Full Text Available La diagraphie acoustique est classiquement utilisée pour fournir la lenteur des formations. Les enregistrements en champ total obtenus dans des puits fortement déviés ou horizontaux peuvent être traités pour fournir des sections de microsismique de puits qui ont une investigation latérale d'une dizaine de mètres par rapport au drain. Cet article présente les résultats d'expérimentations réalisées dans une carrière calcaire située en Bourgogne (France. Un puits fortement dévié (10 degrés a été foré dans l'unité géologique oolithe blanche qui a une épaisseur de 80 m environ. Des diagraphies acoustiques et de la sismique haute résolution ont été enregistrées dans le puits dévié. En diagraphie acoustique, deux jeux de données ont été enregistrés : une section à déport constant et un point de tir commun à très grand nombre de traces et à distance entre traces centimétrique. Le traitement des données met en évidence des réflexions internes a l'oolithe blanche situées à quelques mètres par rapport au drain. La diagraphie acoustique ne permet pas d'éclairer le toit et le mur de l'unité oolithe blanche. Cet objectif est partiellement atteint par une sismique très haute résolution de puits. Ce type de sismique travaille dans une bande de fréquences intermédiaire entre la sismique de puits classique et la diagraphie acoustique. Elle nécessite le développement d'outils particuliers, notamment au niveau des sources de puits. Une collection point de tir commun de données de sismique très haute résolution obtenues avec une source prototype de type impulsionnel montre des réflexions correspondant à des réflecteurs situés à plusieurs dizaines de mètres (~40 m par rapport au drain. Les résultats des expérimentations montrent le potentiel de la diagraphie acoustique et de la sismique haute résolution de puits à décrire une unité réservoir à différentes échelles.

    Full Text Available A qualidade percebida e a satisfação dos clientes são elementos essenciais para a competitividade das instituições bancárias. Assim, é importante identificar os fatores que determinam a percepção de qualidade e satisfação do ponto de vista dos clientes que utilizam esse tipo de serviço. O objetivo deste artigo é a construção de um modelo de relacionamento entre os determinantes de satisfação de clientes e a identificação dos principais atributos que afetam a qualidade percebida dos clientes de serviços bancários. Para isto, foram aplicadas duas pesquisas descritivas. Na primeira fase das pesquisas, utilizou-se a abordagem proposta por Tinoco e Ribeiro (2007 para identificar as relações entre determinantes e construir o modelo de satisfação de clientes. Na segunda fase, foram levantados e hierarquizados os principais atributos de qualidade percebida do ponto de vista dos clientes. Entre os resultados obtidos destacam-se como principais determinantes da satisfação de clientes a confirmação de expectativas e a qualidade percebida. Entre atributos mais importantes que afetam a qualidade percebida podem ser citados: funcionários com conhecimento e habilidade devidos, serviço feito corretamente na primeira vez, tarifas bancárias baratas, transparência e lealdade nas negociações, e presença de funcionários que buscam tornar o serviço mais ágil.Perceived quality and customer satisfaction are essential elements for competitiveness of banking institutions. Therefore, it is important to identify customers' view of banks about drivers of quality perception and satisfaction.

    Full Text Available Este trabalho discute algumas relações entre sofrimento psíquico e trabalho de caixa, em agências bancárias no Rio de Janeiro. Diferentes modelos teóricos são apresentados: Estresse, Psicodinâmica do Trabalho e Psicopatologia do Trabalho. Neste estudo de caso, buscou-se compreender a participação do trabalho na produção do sofrimento psíquico dos caixas de uma grande empresa do setor bancário. A análise do processo de trabalho, com suas variabilidades e dificuldades, revelou que a "diferença de caixa" e as agressões dos clientes representam situações de sofrimento. Essas são situações favorecidas pela organização do trabalho, que obriga os caixas a evitarem as regras de segurança e imputa-lhes a culpa da diferença. Adicionalmente, ela não oferece suporte aos caixas para responder apropriadamente às demandas dos clientes. O contexto de baixos salários e grandes transformações favorece o isolamento dos trabalhadores, gera insegurança com relação ao futuro e é entendida como falta de reconhecimento. Com uma aproximação do trabalho real, é possível entender as situações de trabalho, como elas podem engendrar sofrimento e quais os seus determinantes.

    Full Text Available A pesquisa realizada neste trabalho teve a finalidade de analisar a qualidade percebida pelos clientes de uma agência bancária da Caixa Econômica Federal na cidade de Ribeirão Preto/SP, pois, através dessa análise, será possível identificar os fatores que levam os clientes a perceberem qualidade nos serviços oferecidos pela agência bancária e, dessa forma, além de poder ter a mensuração da qualidade dos serviços ora oferecidos, também poderá gerar novas políticas de melhoria contínua de qualidade. Para tanto foi realizada pesquisa com 120 clientes dentro da própria agência, ou seja, no momento em que o cliente usa do serviço oferecido, ou ainda, como trata a literatura, “no momento do encontro do serviço”. Depois de realizada a pesquisa, foi feita uma análise descritiva e uma análise fatorial, em que a primeira descreve o cenário em relação aos dados dos respondentes. A segunda, foi utilizada por ser considerada a mais apropriada quando se trata de análise de comportamento de consumidor, haja vista sua abrangência em extrair correlações existentes dentre as questões aplicadas. Os resultados expressaram os fatores determinantes da qualidade percebida na visão dos clientes, evidenciando a participação dos funcionários em todos os fatores extraídos na análise, enfatizando assim a importância dos funcionários no contexto de análise.

    2013-12-01

    Full Text Available A moeda e os bancos, na abordagem pós-keynesiana, desempenham um papel central na determinação do emprego e produto, notadamente, em nível regional. Em função disso, o artigo tem por objetivo contribuir para a compreensão, tanto da estratégia de localização dos serviços bancários como do padrão de distribuição das agências bancárias no estado de Minas Gerais. Em princípio, havia fortes indícios de que a localização bancária dependia não apenas de fatores econômicos. O modelo desenvolvido e os resultados encontrados na análise econométrica espacial demonstraram que existe certa dependência espacial na estratégia de localização dos bancos, ou seja, os bancos consideram em sua análise a presença ou não de agências nos municípios onde pretendem se localizar. Ademais, o padrão de distribuição das agências no estado de Minas Gerais está sendo explicado também por fatores macroeconômicos, políticos e regulamentares.

    Full Text Available Seismic anisotropy may degrade the quality of seismic images and cause the mispositioning of events within them. Shales have often been observed to be significantly anisotropic, usually with approximately hexagonal symmetry (transverse isotropy with axis normal to the bedding plane. We investigate the effect of anisotropy on imaging a real data set from offshore Africa, where there are thick shale sequences. We perform, in parallel, isotropic and anisotropic velocity model building and 3D post-stack migration of the same stack volume. We observe that the anisotropic processing improves the focussing of dipping events and that the assumption of isotropy may cause lateral and vertical displacement of the reservoir boundaries, of around 100 and 200 meters respectively, relative to the positions obtained with the anisotropic processing. L'anisotropie sismique peut altérer la qualité des images sismiques et provoquer ainsi un mauvais positionnement. Les argiles se sont souvent révélées avoir des propriétés anisotropes, avec une symétrie presque hexagonale (isotropie transversale sur un axe normal par rapport au plan de stratification. Nous étudions ici l'effet de l'anisotropie sur la migration d'un ensemble de données réelles d'un gisement offshore africain possédant d'épaisses couches d'argile. Nous réalisons en parallèle la création des modèles de vitesse isotrope et anisotrope et la migration du même volume des données stacken utilisant les deux modèles. Nous observons que la méthode anisotrope améliore la mise au point en profondeur et que l'augmentation de l'isotropie peut provoquer un décalage latéral et vertical des limites du réservoir, respectivement de 100 et 200 mètres, par rapport aux positions obtenues avec la méthode anisotrope.

    Full Text Available O setor bancário vem sofrendo inúmeras transformações que implicam na aquisição de novas competências individuais, na qualificação profissional constante, em um contexto caracterizado por inúmeras pressões que contribuem com o desgaste e o desequilíbrio entre o indivíduo e seu ambiente laboral. Frente a este cenário, o suporte no trabalho emerge como um fenômeno de grande relevância, sendo o objetivo deste estudo analisar a percepção dos colaboradores e gestores do setor bancário em relação ao suporte social e organizacional no trabalho, associados as formas de contribuição, valorização e apoio recebidos pelas redes sociais e pela própria organização. Através de uma survey em profundidade, caracterizada como um tipo de pesquisa que além de valer-se da aplicação de questionários, também utiliza entrevistas pessoais para a melhor compreensão do fenômeno, foram investigados 332 colaboradores e 9 gestores, aos quais foram aplicados questionários e entrevistas elaborados a partir dos modelos EPSST e EPSO. Os resultados expõem que a maior incidência foi atribuída ao Suporte Social Informacional, enquanto a menor prioridade refere-se ao Suporte Social Emocional. Em relação ao Suporte Organizacional este apresentou o menor nível de incidência, quando comparado aos tipos de Suporte Social no Trabalho. Nesse sentido esse estudo avançou na linha de entendimento acerca dos aspectos envolvidos nas relações de trabalho associados ao suporte social e organizacional, ampliando as investigações sobre o que os próprios colaboradores entendem e como vivenciam o suporte no trabalho.   Palavras-Chave: Suporte social; suporte organizacional; setor bancário.     ORGANIZATIONAL AND SOCIAL SUPPORT AT WORK: A DIAGNOSTIC IN PUBLIC AND PRIVATE BANKING SECTOR   ABSTRACT The banking sector has undergone many changes involving the acquisition of new individual competencies in the qualification contained in a context

It analyses the implementation, use and enhancement process of three information systems at two banks in Brazil. The research was based on the assumption that information technology is a social construction phenomenon, with a structure of use created in practice. Data were collected through observation, analysis of documents and 46 interviews. A process of social construction was found that produced four types of use of information systems. The system adoption was influenced by the confluence of individual and organizational objectives and by the type of training applied. System updates and reviews seem to follow structures of conformism

    At temperate latitudes densities and biomass of intertidal molluscs tend to be strongly seasonal. Here we provide a comparative study on seasonality of bivalves and gastropods in the tropical intertidal seagrass-covered soft sediment environment of Banc d'Arguin, Mauritania (20°N, 16°W). In this system, benthivorous shorebirds exert considerable predation pressure with strong seasonal variations. It has been proposed that during the period when (adult) shorebirds are absent (May-August) benthic biomass would be able to recover, but a first test was inconclusive. Over a full year (March 2011-February 2012), each month we sampled benthic invertebrates at sixteen permanent sites. The total of 3763 specimens comprised 20 species, representing eight orders and 19 families. Bivalves were much more common than gastropods. The bivalve Loripes lucinalis dominated the assemblage throughout the year (58% of total number), followed by Dosinia isocardia (10%), Senilia senilis (8%) and the gastropod Gibbula umbilicalis (6%). Average biomass amounted to 32 g AFDM/m2, of which the large West-African bloody cockle Senilia made up three-quarter, Loripes 16%, Gibbula 2% and Dosinia 1%. Across the 20 species, lowest densities were reached in late spring (May) and summer (Aug.), whereas highest densities occurred in autumn (Oct.). The lowest overall density of 676 specimens/m² in August more than doubled to a peak density of 1538 specimens/m² in October, most of the increase being due to strong recruitment in both Loripes (densities increasing from 322 specimens/m² in Sept. to 785 specimens/m² in Oct.) and Dosinia (densities increasing from 18 specimens/m² in Aug. to 265 specimens/m² in Sept.). Our results suggest that by the time the feathered molluscivore predators returned in high numbers to Banc d'Arguin (after their summer breeding season in the Arctic), benthic animals were at a peak. In order to quantitatively understand the seasonal changes in mollusc abundance, we

    Full Text Available The present study concentrates on the interpretation of well logs and seismic reflection data in the Jeffara- Dahar region (Southeast part of Tunisia for a better characterization of the Triassic aquifer, a potential target of water supply. Lithological columns and their corresponding well logs reveal that Sidi Stout, Kirchaou and Touareg sandstones as well as Mekraneb and Rehach dolomites are the main reservoirs of the Triassic aquifer. Well log analysis highlights many permeable and fractured layers that could play an important role in the groundwater circulation. The interpreted seismic sections and the resulting isochrone maps show a tectonic influence on the Triassic aquifer geometry in the Jeffara-Dahar region. The normal faulting of E-W and NW-SE accidents created an aquifer compartmentalized by raised and tilted blocks. Seismic cross-sections reveal that this structure controls the depth of permeable formations and the circulation of groundwater. These results will be useful for rationalising the future hydrogeological research that will be undertaken in the Jeffara-Dahar area.[fr] La présente étude concerne l’interprétation des données de la sismique réflexion et celles des puits y compris les enregistrements diagraphiques en vue d’une meilleure caractérisation de l’aquifère triasique de la région de Jeffara-Dahar (Sud-Est de la Tunisie qui constitue une cible potentielle pour l’alimentation en eau.

    The Banc d'Arguin, a non-estuarine area of shallows and intertidal flats off the tropical Saharan coast of Mauritania, is characterised by extensive intertidal and subtidal seagrass beds. We examined the characteristics of intertidal seagrass ( Zostera noltii) meadows and bare areas in terms of the presence and abundance of molluscs (gastropods and bivalves). To explain observed differences between molluscan assemblages in seagrass and bare patches, some aspects of the feeding habitat (top-5 mm of the sediment) and of food (organic materials) of molluscs were examined. The novelty of this study is that phytopigments were measured and identified to assess source and level of decay (freshness) of organic material in the sediment and to study their importance as an explanatory variable for the distribution of molluscs. Over an area of 36 km 2 of intertidal flats, at 12 sites, paired comparisons were made between seagrass-covered and nearby bare patches. Within seagrass meadows, dry mass of living seagrass was large and amounted to 180 ±10 g AFDM m - 2 (range 75-240). Containing twice the amount of silt per unit dry sediment mass, seagrass sediments were muddier than bare areas; the relative amount of organic material was also larger. The total number of species of bivalves and gastropods amounted to 27, 14 of which were found only in seagrass areas, 4 only in bare and 9 in both types of habitat. Among the three numerically most abundant species, the bivalves Anadara senilis, Dosinia hepatica and Loripes lacteus, the first was numerically most abundant in bare and the other two in seagrass-covered areas. Bare intertidal areas had greater mean total biomass of molluscs (80.5 g AFDM m - 2 ) than seagrass meadows (30.0 g AFDM m - 2 ). In both habitats, the bulk of the biomass was made up by A. senilis. Excluding this species, bare mudflats contained on average only 3.1 g AFDM m - 2 and seagrass meadows 6.9 g AFDM m - 2 . As compared to previous surveys in 1980-1986, the

    Banc d'Arguin (BA), Mauritania, is a nationally protected shallow gulf > 10,000 km2 between the Sahara desert and the upwelling system off the Mauritanian coast. In the southeast, BA consists of a 500 km2 tidal flat, the most important wintering site for shorebirds using the East Atlantic Flyway. The Mauritanian upwelling-driven phytoplankton production supports the most productive fisheries worldwide, but little is known about its trophic role in the functioning of the inshore BA food web. Using stable isotopes as trophic tracers to distinguish between upwelling-driven phytoplankton, open ocean phytoplankton, and benthic primary producers, we assessed the spatial extent to which the inshore BA food web is fuelled by upwelling-driven phytoplankton production. The δ13C and δ15N signals were characterized in dominant primary producers, benthic invertebrate taxa, and various fish species along an offshore-inshore (northwest-southeast) gradient. We also monitored the spatial and temporal extent of upwelling entering BA during 2008 with remote sensing of sea surface temperature and chlorophyll a data. The results suggest that benthic invertebrates and fishes living in the northwestern part of BA depend on the nearby upwelling phytoplankton production, but this food source does not support the intertidal benthic community in southeast BA. Furthermore, the isotopic signatures of fishes suggest weak trophic connectivity between the northern subtidal and southeastern intertidal BA. Our results support the hypothesis that the southeastern tidal flat region functions as a distinct ecosystem with a food web supported mainly by local benthic primary production, which is crucial knowledge for effective management of the pristine BA national park.

    Full Text Available Elabora-se um modelo macrodinâmico pós-keynesiano de utilização da capacidade, distribuição e inflação por conflito, no qual a oferta de moeda de crédito é endógena. A taxa nominal de juros é determinada pela aplicação de um mark-up sobre a taxa básica fixada pela autoridade monetária. Ao longo do tempo, o mark-up bancário varia com a taxa de lucro sobre o capital físico, enquanto a taxa básica varia com excessos de demanda que não são acomodáveis pela utilização da capacidade. São analisados os casos em que a demanda é suficiente ou não para gerar a plena utilização da capacidade.It is developed a post-keynesian macrodynamic model of capacity utilization, distribution and conflict inflation, in which the supply of credit-money is endogenous. Nominal interest rate is determined by banks as a markup over the base rate, which is set by the monetary authority. Over time, banking markup varies with firms' profit rate on physical capital, while the base rate rises with any excess demand when capacity is fully utilized. The behavior of the economy is analyzed for the cases in which demand is or is not enough to ensure full capacity utilization.

    Full Text Available Les mécanismes qui régissent l'atténuation sont très complexes et encore mal compris actuellement. Certains mécanismes ont pu être éliminés comme le phénomène de frottement grain à grain du fait des amplitudes de déformation usuelles en sismique. Il. semble que les mécanismes responsables soient différents dans le cas de roches sèches (aux conditions de laboratoire et dans le cas de roches plus ou moins saturées. Dans le cas de roches sèchesl'atténuation semble provenir à la fois d'un hystérésis microcapillaire et d'une rupture des liaisons hydrogènes entre les hydroxyles de la surface et les molécules d'eau. Dans le cas de roches saturées, les candidats les plus probables au phénomène d'atténuation sont les mécanismes de Biot et de squirt flow . Le mécanisme de Biot est la possibilité d'avoir des mouvements différentiels globaux (ou plutôt moyennés à l'échelle de l'échantillon entre la matière solide et le fluide. Le squirt flowconsiste en un phénomène de relaxation visqueuse dont l'excitateur est extérieur : le liquide à l'intérieur de la cavité poreuse jaillit sous l'effet d'une pression de pore locale. The mechanisms governing attenuation are highly complex and still poorly understood at present. Some mechanisms have been eliminated, such as the grain-to-grain friction, due to the usual deformation amplitudes in seismic exploration. The mechanisms responsible for attenuation seem to be different for dry rocks (under laboratory conditions and more or less saturated rocks. For dryrocks, attenuation seems to come from both a microcapillary hysteresis and a break of the hydrogen bonds between the surface hydroxyls and water molecules. For saturated rocks, the most probable causes of attenuation are Biot mechanisms and squirt flow. The Biot mechanism Is the possibility of having overall differential movements (or rather averaged ones on the scale of the sample between the solid matrix and the fluid

    Full Text Available Lors de l'injection d'une solution de tensio-actif dans un gisement déjà balayé par de l'eau, l'huile résiduelle, piégée sous la forme de globules discontinus, est remise en mouvement et se regroupe éventuellement sous la forme d'un banc d'huile. Le but de la présente étude est d'expliquer la formation de ce banc au cours d'un tel déplacement. Les résultats d'expériences réalisées en micromodèles de billes de verre permettent de constater que : - la récupération globale est corrélable avec le nombre capillaire Nc= uVdf/O, u et Vdf étant la viscosité et la vitesse de Darcy du fluide injecté, O la tension interfaciale avec l'huile en place ; - la vitesse des globules varie différemment avec u, Vdf, O et tend vers la même limite plus grande que la vitesse du fluide injecté pour de grandes valeurs du nombre capillaire Nc ; - le banc d'huile ne se forme que dans le cas où la vitesse des globules atteint celle du fluide injecté. L'huile déplacée reste alors groupée avec une saturation importante au niveau du front de tensio-actif. When a surfactant solution is injected into a reservoir previously waterflooded, the residual oil trapped as discontinuous ganglia is mobilized and eventually bunched together forming an oil bank. The aim of this study is to explain the formation of this bank during such a drive. The results of experiments performed in micromodels of glass beads show that: a Overall recovery can be correlated with the capillary number, Nc = uVfd/O, in which u and Vfd are the viscosity a and Darcy velocity of the injected fluid and O is the interfacial tension with the oil in place. b Ganglia velocity varies differently with u, Vfd and O, and it tends towards the same limit faster than the velocity of the injected fluid for high values of the capillary number Nc. c The oil bank is formed only in the case where globule velocity attaints that of injected fluid. the dispaced oil then remains bunched, with high

    Full Text Available Mesmo que o setor bancário brasileiro seja um dos que mais fatura no mundo, os gerentes de agências diversas de bancos públicos e privados encaram diariamente o desafio de manter sua equipe sempre motivada e pronta para encarrar os desafios que o cotidiano do trabalho impõe. A hipótese levantada no presente trabalho estabelece que essa dificuldade ocorre porque os bancos mantêm em cargos de liderança a antiga figura do gerente, não mais adequada para a realidade de instituições que estão em constante mutação e inseridas em um contexto altamente informacional e informatizado. Para comprovar a hipótese levantada, o presente artigo percorre a revisão da bibliografia sobre as temáticas de estilos de liderança, tipos e estilos de líderes e sua aplicação no contexto organizacional contemporâneo das instituições bancárias a fim de mostrar os empecilhos trazidos pela antiga figura do gerente e a necessidade, benefícios e desafios de tornar esta figura em um líder para obter melhores resultados. Por meio da pesquisa exploratória, foram coletadas informações relevantes para análise dos resultados, no qual defronta estilos que a teoria fixa na temática liderança. Por fim, conclui-se que a liderança é um assunto de relevância em qualquer segmento empresarial e no contributo da motivação da equipe.

    ção. Originalidade/ Lacuna/ Relevância/ Implicações: A literatura brasileira sobre eficiência bancária apresenta diversos estudos relacionando a eficiência dos bancos à origem de seu capital e porte. Entretanto, a relação entre eficiência e segmento de atuação foi muito pouco explorada e a relação entre eficiência e classificação de risco é escassa. Neste sentido, a presente pesquisa contribui com a literatura ao explorar a relação entre eficiência e segmento de atuação, bem como a relação entre eficiência e classificação de risco. Principais aspectos metodológicos: A pesquisa utiliza uma abordagem quantitativa e emprega a técnica Data Envelopment Analysis (DEA para calcular os escores de eficiência. Os dados foram obtidos no Banco Central do Brasil (BACEN. Síntese dos principais resultados: Bancos públicos federais e bancos de grande porte são, em média, mais eficientes. Bancos que atuam nos segmentos de câmbio e varejo, bem como bancos com elevada classificação de crédito também obtiveram altos níveis de eficiência. Principais considerações/ conclusões: Bancos eficientes apresentaram-se mais lucrativos, emprestaram menos, como proporção de seu ativo total, e receberam menos reclamações no Banco Central no ano de 2013.

    integrate this additional information directly into an extended bundle adjustment, by adding a constraint term in the weighted cost function. We evaluate three methods (based on machine learning or regularization) that dynamically select the weight associated to the constraint and show that these methods can be used in a real time multi-sensor SLAM, and validate them with different types of constraint on the orientation or on the scale. Experiments conducted on real video sequences show that this technique of constrained bundle adjustment reduces the drifts observed with the classical vision algorithms and improves the global accuracy of the positioning system. (author) [French] Les travaux presentes dans ce manuscrit concernent le domaine de la localisation et la reconstruction 3D par vision artificielle. Dans ce contexte, la trajectoire d'une camera et la structure 3D de la scene filmee sont initialement estimees par des algorithmes lineaires puis optimisees par un algorithme non-lineaire, l'ajustement de faisceaux. Cette these presente tout d'abord une technique de recherche de l'amplitude de deplacement (recherche lineaire), ou line search pour les algorithmes de minimisation iterative. La technique proposee est non iterative et peut etre rapidement implantee dans un ajustement de faisceaux traditionnel. Cette technique appelee recherche lineaire algebrique globale (G-ALS), ainsi que sa variante a deux dimensions (Two way-ALS), accelerent la convergence de l'algorithme d'ajustement de faisceaux. L'approximation de l'erreur de reprojection par une distance algebrique rend possible le calcul analytique d'une amplitude de deplacement efficace (ou de deux pour la variante Two way-ALS), par la resolution d'un polynome de degre 3 (G-ALS) ou 5 (Two way-ALS). Nos experimentations sur des donnees simulees et reelles montrent que cette amplitude, optimale en distance algebrique, est performante en distance euclidienne, et permet

    Full Text Available Seismic monitoring is commonly used in the oil industry to follow the evolution of reservoir properties during production. We present a methodology of time-lapse (or 4D stratigraphic inversion, which is able to provide an estimation of P- and S-wave impedance variations in the reservoir by inverting prestack time-lapse seismic data. The 4D inversion is implemented in the time domain and requires a time scaling law for each repeated seismic dataset in order to adjust the arrival times of homologous events observed in the so-called reference and monitor datasets. This operation is often referred to as the warping problem. The 4D inversion is a 3-step methodology. The first step consists in inverting each seismic vintage independently, thus providing as many P- and S-wave impedance distributions as datasets considered. The second step uses the available P-wave impedance information to solve the warping problem which is crucial to the third and final step: the joint inversion of all available seismic vintages. This 4D inversion sequence was applied to seismic datasets recorded on the Norwegian CO2 storage reservoir of Sleipner field located in the North Sea. The latter is becoming a reference industrial site for the long-term storage of carbon dioxide (CO2 in a saline aquifer, the Utsira sand formation. We focused our 4D inversion study on the 1994 and 2006 vintages acquired two years before and ten years after the beginning of CO2 injection, respectively. The warping correction resulted in a time-scaling law with a maximum pushdown effect of about 45 ms at the base of the Utsira aquifer. The joint 4D inversion results show more consistency than the single 3D inversion results: the 4D inversion notably provides P-wave impedances for the CO2 -saturated sandstones which are close to the values derived from rock physics studies. Le monitoring sismique est couramment utilisé dans l'industrie pétrolière pour suivre l'évolution des propriétés des r

Predominaron en las entrevistas sentimientos de frustración e inseguridad sobre el trabajo y la preocupación por la presión psicológica de la necesidad de logro de los objetivos.O setor bancário brasileiro passou por intenso processo de reestruturação e ocupou posição de liderança na incorporação de novas tecnologias e inovações organizacionais. A informatização do setor, aliada às novas formas de organizar o trabalho, resultou em mudanças que refletiram na saúde dos trabalhadores. Fundamentado no referencial teórico metodológico do materialismo histórico-dialético, este estudo, de caráter qualitativo, teve por objetivo investigar as condições de trabalho de bancários, para identificar em que medida as mudanças na organização do trabalho interferiram na saúde daqueles trabalhadores. Os dados foram coletados através de entrevistas com onze bancários. Os resultados revelaram, além de adoecimentos de ordem física por doenças ocupacionais, diretamente relacionadas à intensificação do trabalho, o aumento da incidência de sofrimento mental e sentimento de perda de identidade profissional. Predominaram, nos depoimentos, sentimentos de frustração e insegurança em relação ao trabalho e preocupação com a pressão psicológica, derivada da necessidade de cumprimento de metas.

    Full Text Available It presents problem resulting from the absence of assets belonging to the executed party in the civil execution. It particularly investigates the crisis generated by the absence of assets, as well as the procedure carried out in order to locate assets that can be seized. It also examines the issue pertaining to banking and fiscal privacy, including an exhibition of the theorical bases of the institutes, juridical disciplines and the doctrinal and jurisprudential position on the theme. It highlights the fact that both banking privacy and fiscal privacy are based on the right to privacy, and thus posses constitutional consent. It reinforces the relativity of the right to privacy which enables the executor to have acess to the information pertaining to banking and fiscal data belonging to the executed party, once all attempts at locating assets have been implemented without success. The dissertation affirms that a contrary judicial decision does not fulfill the principle of effectiveness of procedure. It concludes that the right to credit of the executor is also in the interests of justice, and thus the right to privacy must give way when confronted by the interests, as a result of the application of the principle of proporcionality.Trata da problemática resultante da ausência de bens do executado no processo de execução.

Ainsi, l'élément central dans le modèle de milieu discret dont on parle est la structure de fissuration (dislocation et la distribution caractéristique de l'état de contrainte (pression. Il est évident que dans de tels modèles de systèmes discrets les principaux paramètres des processus liés au fluide seront déterminés par la densité de dislocation et la grandeur de la pression générale opérant sur ce volume de milieu. Avec cela la pression générale est définie comme la somme de la pression lithostatique et de la pression anomalique où le terme de pression anomalique dans le cas précis reflète la variabilité caractéristique de l'état de tension des systèmes discrets ayant un soubassement mobile. En tenant compte de ces conditions le milieu considéré est défini comme un modèle de dislocation fluidique (DFM. Dans le modèle DFM la nature de la variabilité des propriétés physiques dans un espace réel de série sédimentaire est défini - en premier par la valeur du volume du milieu considéré - en second par la densité de dislocations et la valeur de la pression, et seulement - en troisième par les propriétés de chaque briquedont la pluralité constitue le milieu. Le résultat des études théoriques et expérimentales du processus de propagation des ondes élastiques dans le DFM nous amène à une interprétation complètement différente de la nature et des propriétés des limites sismiques : les réflecteurs physiques réels d'ondes élastiques sont les surfaces de dislocation tandis que les paramètres dynamiques de réflexion sont formés par la valeur de la pression agissant sur la surface de dislocation donnée ou l'ensemble des dislocations dans le volume d'onde observé de l'espace.

    Full Text Available Este trabalho discute algumas relações entre sofrimento psíquico e trabalho de caixa, em agências bancárias no Rio de Janeiro. Diferentes modelos teóricos são apresentados: Estresse, Psicodinâmica do Trabalho e Psicopatologia do Trabalho. Neste estudo de caso, buscou-se compreender a participação do trabalho na produção do sofrimento psíquico dos caixas de uma grande empresa do setor bancário. A análise do processo de trabalho, com suas variabilidades e dificuldades, revelou que a "diferença de caixa" e as agressões dos clientes representam situações de sofrimento. Essas são situações favorecidas pela organização do trabalho, que obriga os caixas a evitarem as regras de segurança e imputa-lhes a culpa da diferença. Adicionalmente, ela não oferece suporte aos caixas para responder apropriadamente às demandas dos clientes. O contexto de baixos salários e grandes transformações favorece o isolamento dos trabalhadores, gera insegurança com relação ao futuro e é entendida como falta de reconhecimento. Com uma aproximação do trabalho real, é possível entender as situações de trabalho, como elas podem engendrar sofrimento e quais os seus determinantes.This article discusses key relations between psychological distress and bank tellers' working conditions in various bank offices in Rio de Janeiro. Different theoretical models are discussed: stress, the psychodynamics of the work, and the psychopathology of the work. The aim of this case study was to elucidate the role of the work process as a source of psychological distress among tellers in a large bank company. Analysis of the work process with its variability and difficulties showed that two highly stressful situations are 1 discrepancies in the amounts of money counted at the teller's window and 2 customer complaints or insults directed against the teller. Such situations arise from the work organization that forces tellers to streamline or skip security

    Full Text Available O estudo da rentabilidade bancária envolve duas linhas de discussão: (1 a performance dos bancos é importante para garantir a solidez da instituição e a estabilidade do sistema e (2 rentabilidade elevada pode indicar comportamento oportunista dos bancos, associado a um mercado concentrado. O propósito deste estudo é avaliar a evolução do grau de concentração da indústria bancária no Brasil e verificar se há relação entre o nível de rentabilidade das instituições e o grau de concentração do setor, utilizando ativos totais, operações de crédito e depósitos bancários, entre janeiro/2000 e dezembro/2009. Tendo como benchmark os parâmetros das autoridades antitruste brasileiras, não foram encontradas evidências de concentração no setor, embora o indicador de concentração tenha aumentado substancialmente a partir do final de 2008. Utilizando os parâmetros considerados nos EUA, foi constatado que, no final do período analisado, os indicadores mostram uma situação de "concentração moderada". Como um segundo objetivo do trabalho, foram testadas hipóteses baseadas no paradigma estrutura - conduta - performance, que pressupõe que menor competição decorrente de maior concentração resultaria em maior rentabilidade das instituições. Os resultados não corroboram as hipóteses em nenhuma das combinações de testes realizadas, seja porque os parâmetros são não significativos ou porque são negativos. Não são confirmadas, portanto, as previsões de que a maior concentração do mercado explicaria uma maior rentabilidade das instituições financeiras, conforme a hipótese estrutura - conduta - performance (HCP. Ao contrário, foram obtidas evidências de que a hipótese de estrutura eficiente (HEE explica, mais adequadamente, a rentabilidade no setor bancário nacional.The study of bank profitability involves two lines of discussion: (1 bank performance is important to guarantee the strength of the institution

    Full Text Available Treinamentos corporativos realizados via Intranet têm sido cada vez mais frequentes e o desafio de avaliá-los torna-se presente para pesquisadores e profissionais. Na pesquisa aqui apresentada, o objetivo foi verificar a efetividade de um treinamento a distância. Para tal, foi avaliado um curso na área comercial oferecido por uma instituição bancária de grande porte para seus funcionários. Foram aplicadas cinco escalas a 742 funcionários - atitudes dos participantes em relação à educação a distância, avaliação de necessidade do treinamento, suporte à aplicação do treinamento, impacto do treinamento no trabalho (profundidade e amplitude. Foram realizadas análises de componentes principais, fatoriais exploratórias e de consistência interna, teste t, correlações e regressão múltipla padrão. Nos resultados, revelou-se que os participantes que perceberam maior suporte na aplicação do treinamento, que tinham atitudes mais favoráveis à educação a distância e, sobretudo, que percebiam maior necessidade do treinamento, relataram maior ocorrência de impacto do treinamento no trabalho. Os achados sugerem maior atenção para a fase de diagnóstico de necessidades de capacitação, bem como disseminação contínua das vantagens da educação a distância em ambientes corporativos.

    Document available in extended abstract form only. ANDRA is directly responsible for all scientific data acquired in real time and wire-line at the Meuse Haute- Marne underground research laboratory. To fulfil the needs for the acquisition, storage and display of realtime data, Andra decided to develop and install a system called SAGD (Systeme d'Acquisition et de Gestion des Donnees). With this view, a system was designed to: - Determine the acquisition tools and methods so that technical failures would not result in the loss of data or the acquisition of erroneous data, - Store (conservation) in the long-term all data in a single place in a single form, - Allow the diffusion and free access of data to the large community of ANDRA researchers, partners and service contractors in a single fluid way whatever the source of the data. - Help external communication through a user friendly and easy to understand presentation of the recorded data. S.A.G.D fulfils these objectives by: - Making available in real time, and through a single system, all experimental data under acquisition at the MHM Center and Mont Terri laboratory, - Displaying the recorded data on temporal windows and specific time step, - Allowing remote control of the experimentations, - Ensuring the traceability of all recorded information, - Ensuring data storage in a data base. S.A.G.D has been deployed in the first experimental drift at -445 m in November 2004. It was subsequently extended to the underground Mont Terri laboratory in Switzerland in 2005 and to the entire surface logging network of the Meuse / Haute-Marne Center in 2008. The SAGD computer network is an autonomous network consisting of optical fiber links which transmits experimentation data to the servers and computers in the control room, whether they originate from the bottom of a borehole or surface level. A high speed link between Mont Terri and Bure allows remote control of all the experimentations and the centralization of all

    The authors used gamma cardiology during the abatement of 16 cases of asthma with a view to detecting heart attacks not otherwise visible with routine methods of examination: clinical, radiological and electro-cardio-graphical. In gamma cardiology, a radioactive indicator is used and its path followed in the cavities of the heart. The method makes it possible to study the circulation in the right heart, the pulmonary crossing, and the left heart, as well as evaluation of the heart-flow. As a result of their investigations the authors, after having discussed the significance of the data obtained with the method, suggest that it is possible by the use of gamma cardiography during the abatement of an asthma attack: 1- To confirm attacks of the right heart which have already been detected by ordinary methods. 2- To confirm the presence of modifications in the recorded curves which suggest, in the case of the left heart, possible attack; such on attack is also indicated, in a small number of cases, by electrocardiography curves. Some considerations are put forward by the authors concerning the physiopathology of attacks on the left heart.

    Full Text Available The deep drilling campaign in the Niger Delta has demonstrated the need for a detailed geopressure and trap integrity (drilling margin analysis as an integral and required step in prospect appraisal. Pre-drill pore pressure prediction from 3-D seismic data was carried out in the Greater Ughelli depobelt, Niger Delta basin to predict subsurface pressure regimes and further applied in the determination of hydrocarbon column height, reservoir continuity, fault seal and trap integrity. Results revealed that geopressured sedimentary formations are common within the more prolific deeper hydrocarbon reserves in the Niger Delta basin. The depth to top of mild geopressure (0.60 psi/ft ranges from about 10 000 ftss to over 30 000 ftss. The distribution of geopressures shows a well defined trend with depth to top of geopressures increasing towards the central part of the basin. This variation in the depth of top of geopressures in the area is believed to be related to faulting and shale diapirism, with top of geopressures becoming shallow with shale diapirism and deep with sedimentation. Post-depositional faulting is believed to have controlled the configuration of the geopressure surface and has played later roles in modifying the present day depth to top of geopressures. In general, geopressure in this area is often associated with simple rollover structures bounded by growth faults, especially at the hanging walls, while hydrostatic pressures were observed in areas with k-faults and collapsed crested structures.

    Full Text Available O texto apresenta a análise da relação entre a qualificação profissional e a reinserção produtiva de ex-funcionários do Banestado que aderiram aos Programas de Demissão Voluntária (PDV dos anos de 1997, 1998 e 1999. O estudo partiu de entrevistas com ex-bancários pedevistas de Curitiba e Região Metropolitana, buscando verificar o significado e a importância da qualificação profissional obtida durante a atividade bancária para o desempenho da nova atividade profissional. Os dados das entrevistas surpreenderam, pois houve a reinserção para praticamente todos os pedevistas. Contundo, ratificaram os estudos acerca das transformações do mundo do trabalho, pois a maioria das reinserções ocorreram em condições de maior precariedade. Outro dado substantivo, desafiador e determinante para a análise pretendida, foi a convicção dos pedevistas em afirmar a decisão correta em aderir aos referidos programas, mesmo reconhecendo a importância do banco em suas vidas, em especial ao acúmulo de experiências em decorrência das múltiplas oportunidades profissionais na instituição e o reconhecimento das condições de trabalho proporcionadas pelo Banestado serem melhores do que as relativas a atividade profissional. Concluiu-se que realmente houve uma articulação entre a reinserção produtiva e a qualificação profissional dos pedevistas, além do que, muito provavelmente, no Banestado tais programas cumpriram o papel administrativo ao reduzir a força de trabalho e o papel político ao diminuir a resistência do corpo funcional através do desligamento de parcela significativa de seus trabalhadores, principalmente dos que tinham mais tempo de banco e que teriam mais elementos para justificar a existência e a continuidade do Banestado perante o processo de privatização.This text presents the process of reintegration of former Banestado Bank employees to the labour market after a wave of voluntary lay-offs which took place

    Full Text Available As mudanças oriundas da globalização e a disseminação das tecnologias da informação possibilitaram à sociedade a compreensão de seu poder de mercado e influência sobre as organizações, acarretando na pressão social sobre as empresas para que estas adotem práticas socialmente responsáveis. No setor bancário, contudo, as exigências da sociedade não são tão perceptíveis quanto em outros setores, assim como são poucos os estudos sobre práticas de responsabilidade social (RSE em bancos. Além das questões ambientais, deve-se considerar a RSE, envolvendo a atenção e cuidado com funcionários e fornecedores, a transparência na comunicação e nas formas de marketing utilizadas e a ética nas relações com a sociedade. Estudos sobre a RSE em bancos devem considerar os impactos econômicos do setor, o qual é considerado um dos principais no que tange à contribuição para a estabilidade e o crescimento econômico. Assim, o presente estudo procurou verificar o estágio de desenvolvimento da RSE em uma unidade do Banco do Brasil, localizada no Município de Areia, Paraíba. Para tanto, utilizou-se de uma análise quantitativa sobre os dados coletados por meio de um questionário estruturado. Os resultados apontam que, embora a unidade do Banco do Brasil estudada apresente certa preocupação com a RSE, são poucas ações que vão além da obrigação legal.

  5. Avaliação de estratégias para a redução do risco de inadimplência em carteiras de crédito bancário rotativo de pessoas físicas Assessment of default risk reduction strategies in revolving credit portfolios of individual borrowers

    Full Text Available Os principais Bancos Privados brasileiros vêm apresentando crescimento contínuo do número de clientes pessoas físicas em suas carteiras de crédito e, conseqüentemente, aumento do volume de negócios e receitas com as altas taxas de spread, ou retorno, cobradas em empréstimos rotativos (ex.: Limite de Cheque Especial. Como, paralelamente ao aumento da concessão de empréstimos, ocorre uma maior exposição ao risco de inadimplência, espera-se que os Bancos adotem ações preventivas e inibidoras ao não pagamento pontual de empréstimos. Visando contribuir nessa tarefa, este artigo, inicialmente, apresenta três proposições para a redução de risco em carteiras de crédito bancário rotativo às pessoas físicas, quer sejam: 1 "O Agente Desestimulador ao Risco Moral", 2 "A Determinação da Fronteira Eficiente Risco-Retorno" e 3 "O Mercado Futuro de Índices de Inadimplência". Na parte final, apresenta um modelo econométrico desenvolvido para avaliar o impacto de 19 variáveis sistemáticas na inadimplência de pessoas físicas em créditos rotativos. Os resultados extraídos de simulações conduzem à conclusão parcial de que a utilização do modelo econométrico e a implementação das três estratégias contribuiriam para a inibição e melhor monitoramento da inadimplência em carteiras de crédito rotativo de pessoas físicas.In recent years, the main private Brazilian banks have presented a continuous increase in the number of clients in their portfolios and, consequently, successive growth of credit operations and revenues obtained through the high interest rates or spread charged on loans to individual borrowers, such as credit limit and revolving credit. Moreover, the increase in the number of clients also increases the risk of default. Hence, it is essential that banks carry out strategies to implant default prevention actions. In order to contribute to this endeavor, this paper presents three propositions or action

  6. A previsibilidade nas condenações por danos morais: uma reflexão a partir das decisões do STJ sobre relações de consumo bancárias The predicability of moral damages lawsuits' results: a reflection based upon STJ' decisions in bank-consumer relations

    2009-06-01

    Full Text Available A previsibilidade do resultado dos processos judiciais é uma das facetas do princípio da segurança jurídica, princípio este norteador do sistema jurídico pátrio. O método do livre arbitramento adotado pelo Código de Processo Civil concede ampla liberdade aos juízes na fixação do montante indenizatório por danos morais, o que pode significar que não há como prever o valor condenatório. Por outro lado, a jurisprudência pode contornar a imprevisibilidade por meio da uniformização de suas decisões. A tendência em adotar determinados critérios na quantificação do dano moral ou em limitar a indenização à determinada faixa de valores permitiria um prognóstico do resultado que será obtido com a demanda indenizatória, caso procedente. Pautada pelo objetivo de identificar como a opção legislativa do livre arbitramento é interpretada e aplicada pela jurisprudência do Superior Tribunal de Justiça, a pesquisa restringiu-se às relações de consumo bancárias, cujos valores indenizatórios foram revistos pela corte especial, em sede de recurso especial, no período de outubro de 2000 e abril de 2007. Em geral, a intervenção do Superior Tribunal de Justiça se faz sentir pela redução substancial dos valores fixados nas instâncias anteriores. Assim, o presente trabalho também põe em relevo a possibilidade de, na prática, haver um limite monetário ou tarifação dos valores indenizatórios, no âmbito da corte especial e de indagar se o suposto tabelamento pode funcionar, futuramente, como inibidor do ajuizamento de processos judiciais pelos consumidores lesados.The predictability of the lawsuits' results is one of the facets of the principle of legal certainty, wich is Brazilian legal system´s guide. The method of free quantification adopted by the Civil Procedure Code grants freedom to judges when determining the moral damages compensatory amount, what may result in not being able to predict the indemnification

    In its technical report SIA 2028 the Swiss Society of Engineers and Architects (SIA) published for the first time uniform climatic data for building planners. Previously, each building standard included the data just needed by the topic addressed. In different standards, different data could be found for the same meteorological quantity. Very confusing indeed. The new publication will be used in applying every building standard in Switzerland, leading to a uniform data basis for all projects. By the way the published data were updated, according to the global climatic change that is particularly pronounced in the Alpine region. The orography creates in Switzerland a high number of microclimates, even though the territory has only 41,000 km{sup 2}. Twelve climatic regions are distinguished and the data originate from 40 meteorological stations. The SIA 2028 data are also electronically available.

    Like terrestrial seismology, asteroseismology is the study of star quakes. These internal vibrations are detected by observing the luminosity (or velocity) variations at the stellar surfaces. From these time series, one computes power spectra which contain a wealth of information. In particular, for solar-like pulsators, we are able to observe the signal of granulation as well as the eigenmodes of stellar oscillations, both of which are a direct consequence of the convection in the star's envelope. Asteroseismology allows us to probe the interior of stars much like an ultrasound. Furthermore, with the large spatial photometric surveys CoRoT and Kepler, a new scope for seismology appeared. Indeed, it is possible to characterise to first order the oscillation spectra of solar-like pulsators with few indices or parameters, called seismic indices. Using simple relations, they allow us to estimate fundamental parameters of these stars. Asteroseismology is by consequence a very powerful tool for the study of stellar populations. In the perspective of the development of the Stellar Seismic Indices (SSI - see http://ssi.lesia.obspm.fr/) database, the purpose of my thesis was to develop an automatic method able to extract simultaneously the seismic indices and the parameters characterizing the granulation signature of solar-like pulsators. This method, called MLEUP, was optimized for red giants because for the few hundred main-sequence solar-like pulsators observed by CoRoT and Kepler, several tens of thousands of red giants have been observed by these same missions. MLEUP has a major advantage over most existing methods: it relies on the use red-giant stellar oscillation universal pattern (UP) to fit the oscillation spectra. This allows us to analyse the unsmoothed spectrum and fit simultaneously both granulation and oscillations with the maximum likelihood estimate (MLE). As a first step, MLEUP was tested on Monte Carlo simulations in order to quantify its performances. These simulations have revealed that MLEUP achieves very good performances, with low biases and dispersions. As a second step, we applied MLEUP to more than 36,500 stars observed by CoRoT and Kepler, thereby yielding seismic indices and granulation parameters for more than 13,500 stars. Those results have already been used in several works and are expected to be used in many more. Soon, the entire CoRoT dataset will be analysed. Thus, with the CoRoT and Kepler observations, we expect to obtain, seismic indices and granulation parameters for around 18,000 red giants in total. These results will be made available for the scientific community via the SSI database.

    2011-01-01

    Full Text Available The object of the paper is represented by an attempt to contribute to an adaptation of the concept of seismic intensity to the needs of engineering activities. A first condition in this connection is to pay the attention due to the spectral contents of ground motion. A case where rough approaches have led to erroneous estimates of ground motion severity, resulting in erroneous hazard estimates is presented. The main conclusion derived is represented by the strong need to specify the spectral interval for which macroseismic data are relevant and, as a consequence, to consider (and even to define seismic intensity derived from post-earthquake surveys as related to a certain spectral interval. A methodology proposed in order to define and determine seismic intensity on the basis of instrumental data and, moreover, to define and determine seismic intensity spectra is then presented. Some illustrative examples are given.

    Koubaa, Zied

    The communication network and the detection mechanisms are two critical systems in a plane. Their performance has a direct impact on aircrafts. This is of particular interest for avionics designers, who have increasingly invested more and more in the development of these elements. As a part of a project in this domain, we introduce the design and the development of a smart interface for position sensors dedicated to flights (Smart Sensor Interface - SSI). This interface will serve to connect sensors of different technologies (electromagnetic, optical and MEMS) to the new communication network, AFDX. The role of this interface is to generate an appropriate excitation signal for certain types of sensors (R/LVDT), and to treat, demodulate, and digitize their output signals. The proposed interface is thus composed of a Signal Acquisition Path (SAP) and an Excitation Signal Generation (ESG). By adopting the Integrated Modular Avionics architecture (IMA), we can minimize the size of the classic interface, reduce its energy consumption and improve its reliability and its performance. The focus of our design is particularly on the Data Acquisition Path (DAP). An Architecture characterized by a high resolution (14 bits) and a low latency (1.2 ms) of this module is introduced and developed in this prestigious work. This architecture was developed after a wellconducted study of existing solutions found in literature work and a detailed analysis of the problems arise in the design and implementation of this system (DAP). The conversion of the sensor signal into a digital signal is the most important step in acquiring data, as it sets the resolution of the acquired information and generates the majority of its latency. This module can also affect the reliability and stability of the system. Among different models and architectures, the Delta-Sigma analog-to-digital converter (ADC) is preferred for this application (for better resolution). This converter is formed by an analog circuit (modulator) followed by digital filters. The complexity of the implementation, the processing delay and the output resolution are all susceptible to change depending on the architecture of these filters. Thus, the main problem while designing such a system arises in the opposing evolution of the resolution and latency parameters; the improvement or evolution of one, results in the destruction of the other. Therefore, our work aims to provide one or more method to optimize the latency caused by the CAN while maintaining the same resolution of the desired data (14 bits). This optimization takes into account the objective of integrating the DAP in modules of small size and low power consumption. This proposed solution was implemented in order to validate the design of the conception of the interface. We are also interested to achieve the proposed solution and validate our design. The obtained results will be evaluated after following the manufacturing strategy. The data acquisition unit is made up of two electronic components. The first component is an integrated circuit, which uses CMOS 0.13mum IBM technology and contains the analog part of CAN (SigmaDelta modulator). The second component is a Virtex-6 FPGA, which allows one to acquire the necessary digital processing required for the acquisition and conversion of the sensor signal. In the final version of the interface, our analog portion will be integrated with the analog portion of GSE in the same chip. The integrated digital logic in the (FPGA) role will thus provide digital data to the ESG module in order to generate the excitation signal.

    Reirradiation represent an unfrequent particular clinical situation. The risk/benefit ratio assessment must be taken into account, considering both clinical and dosimetric aspects. There is a relatively limited amount of preclinical data available to date and clinicians should cautiously perform re-irradiations in selected indications. This review summarizes the experimental data available on reirradiation of normal tissues, the consequences on early and late toxicities as well as the intrinsic limitations of these models.

    This presentation outlined the corporate history of the Ohmega Group, a small company from Gaspe, Quebec which offers consulting services to the automation and telecommunication sector. It was created in 1982 and has been involved with the wind power industry since 1996. The main services provided by Ohmega Group include electrical and mechanical construction and maintenance services. This paper also reviewed the benefits of using Supervisory Control and Data Acquisition (SCADA) systems in the wind power industry to monitor, control and collect data from wind turbines. The Ohmega Group has provided consulting services to Cartier Wind Energy Inc., a company that was awarded several wind turbine projects by Hydro-Quebec Distribution. The Ohmega Group applied the SCADA system at the Baie des Sables, Anse a Valleau and Carleton wind turbine arrays. The typical architecture of SCADA systems on a wind farm was presented along with Hydro-Quebec's specifications for data acquisition. The presentation emphasized that wind producers must define their own needs, define the externalities of their project and archive operation and maintenance data from the onset of projects. tabs., figs.

    Portal vein and mesenteric vein gas are unusual conditions with a complex and nuclear pathogenesis. Mesenteric ischemia frequently causes such pathological conditions but a variety of other causes are known: inflammatory bowel disease, bowel distension, traumatic and iatrogenic injury, intra-abdominal sepsis, and idiopathic conditions. This pathologic entity is favored by intestinal wall alterations, bowel distension and sepsis. The prognosis is frequently fatal, especially when associated with extended bowel necrosis although in the majority of the cases, outcome is favorable without surgery. (author)

    The results of several major epidemiology studies on populations with particular exposure to ionizing radiation should become available during the first years of the 21. century. These studies are expected to provide answers to a number of questions concerning public health and radiation protection. Most of the populations concerned were accidentally exposed to radiation in ex-USSR or elsewhere or in a nuclear industrial context. The results will complete and test information on risk coming from studies among survivors of the Hiroshima and Nagasaki atomic bombs, particularly studies on the effects of low dose exposure and prolonged low-dose exposure, of different types of radiation, and environmental and host-related factors which could modify the risk of radiation-induced effects. These studies are thus important to assess the currently accepted scientific evidence on radiation protection for workers and the general population. In addition, supplementary information on radiation protection could be provided by formal comparisons and analyses combining data from populations with different types of exposure. Finally, in order to provide pertinent information for public health and radiation protection, future epidemiology studies should be targeted and designed to answer specific questions, concerning, for example, the risk for specific populations (children, patients, people with genetic predisposition). An integrated approach, combining epidemiology and studies on the mechanisms of radiation induction should provide particularly pertinent information. (author)

    Full Text Available The aim of this study is to develop a scale in order to identify and classify the most valued attributes of retail banks by their customers. There is a shortage of studies about customer value that take into account variables such as economic sectors, customer segments or geographic regions, thereby allowing greater precision on developing strategies to conquer customer loyalty in present and future transactions. The methodology applied relies on solid conceptual and theoretical thinking and gathered procedures recommended by recognized authors, including the triangulation process, which emphasizes the qualitative approach as a support for quantitative analysis. Purification processes and several qualitative and quantitative tests provide reliability and validity to the scale. The results also show that specific scales are more precise when it comes to explaining marketing phenomena related to customer value in addition to the relevance of the methodology for further studies in that field. This notwithstanding, further studies are recommended in order to confirm the validity of the proposed scale.

    Progress in the field of seismic qualification and design methods made these last few years allows physical phenomena actually in play to be better considered, while cutting down the conservatism associated with some simplified design methods. So following the change in methods and developing the most advantageous ones among them contributes to the process of the seismic margins assessment and the preparation of new design tools for future series. In this paper, the main developments and improvements in methods which have been made these last two years in the Code Aster, in order to improve seismic calculation methods and seismic margin assessment are presented. The first development relates to making the MISS3D soil structure interaction code available, thanks to an interface made with the Code Aster. The second relates to the possibility of making modal basis time calculations on multi-supported structures by considering local non linearities like impact, friction or squeeze fluid forces. Recent developments in random dynamics and postprocessing devoted to earthquake designs are then mentioned. Three applications of these developments are then ut forward. The first application relates to a test case for soil structure interaction design using MISS3D-Aster coupling. The second is a test case for a multi-supported structure. The last application, more for manufacturing, refers to seismic qualification of Main Live Steam stop valves. First results of the independent validation of the Code Aster seismic design functionalities, which provide and improve the quality of software, are also recalled. (authors). 11 refs.

    The seismic risk taken into account during the sizing of the nuclear power plant of Fessenheim seems to have been under evaluated at this time. The revaluation of the seismic risk, as proposed, until this day by EDF in order to the third ten-year visit of the power plant, planned for 2009, leads to a significant under evaluation of the risk and then is not acceptable. The present expertise details point by point the weaknesses of these revaluation. The power plant has been sized in an elastic manner that is generally strongly for the safety side. It is imperative to proceed the most quickly as possible to a deep control of the seismic resistance of the power plant of Fessenheim and then after having proceeded to a revision of the seismic risk in taking into account the actual knowledge in this field.

    PLC (Power Line Communications) in Europe or BPL (Broadband over Power Lines) in the US are techniques that allows the utilization of low and middle voltage power lines for the transmission of high frequencies by coupling electrical signals to them. In this way, unshielded power lines may be used for the transmission of numerical information similar to the well known xDSL-techniques using telephone lines. Typically, the frequency range used by PLC is between 9 kHz and 30 MHz. The authors describe the general principles and investigate possible electromagnetic interference with existing radio frequency equipment like xDSL, CATV (Cable Television) and Wireless (GSM, Bluetooth, WiFi). Finally, they present theoretical and experimental results of techniques allowing the reduction of such interference by reducing the emission of electromagnetic signals from PLC systems. The preferred method is based on an active control by injecting an auxiliary signal into the third conductor (ground)

    The Chemistry-Transport Models (CTM) are now sufficiently efficient to simulate realistic photochemical pollutant concentrations. Nevertheless, the complexity of involved processes and the temporal and spatial variability of the emission sources make it impossible to perfectly reproduce pollutant concentrations. If an intrinsic parameter or an input is not well described, A huge error results. CHIMERE is a CTM which covers the major part of Europe with a resolution of about fifty kilometers. It offers the possibility to zoom and simulate pollutant concentrations in a more detailed way over some key regions, such as Ile-de-France and the Berre and Marseille regions. We present results of a comparison of the continental and regional simulations with surface observations and aircraft measurements from the ESQUIF campaign (Etude et Simulation de la QUalite de l'Air en Ile-de-France). This comparison allows us to quantify the total error made in ozone and nitrogen dioxide concentrations. We also present different methods (e.g. Statistical Interpolation and Kriging) we have tested and adapted to the pollution case in order to correct this error. We compare the methods and show in an objective way that it is possible to obtain more realistic three-dimensional maps of pollutants (e.g. analyses) by combining both simulations and surface observations. A series of real time experiments realized in the PIONEER project show that the forecast error may propagate from one region to another. The european scale ozone analyses are thus used to re-initialize the forecast model. The aim is then to answer the question of whether it possible to improve short time forecasts by using better initial values instead of the forecasts for the day before. (author)

    The motivation to build up the database BDFGeotherm was to put at the disposal of the geothermal community a comprehensive set of data on the deep fluids of Switzerland and of some neighbouring areas. Researchers, engineers and all persons wanting to know the type and properties of geothermal fluids existing in a given area or underground system can find in BDFGeotherm a wealth of information which are generally widely dispersed and often difficult to reach. The BDFGeotherm database has been built under Microsoft ACCESS code and consists of nine tables connected with a primary key: the field 'Code'. A selection of parameters has been chosen from the following fields: general and geographical description, geology, hydrogeology, hydraulics, hydrochemistry and isotopes and finally geothermal parameters. Data implemented in BDFGeotherm are in numerical or in text format. Moreover, in the field 'Lithological log', one can visualize and save bitmap images containing lithological logs of boreholes. A total of 203 thermal springs or deep boreholes from 82 geothermal sites are implemented in BDFGeotherm. Among the 68 Swiss sites, a large majority of them are located in the northern part of the Jura range and in the upper Rhone valley (Wallis). Some sites, in Germany (5), France (3) and Italy (6), were selected for the following reasons: located near Swiss hot springs or deep boreholes, having similar geological features or representing a significant geothermal potential. Many types of queries could be realised, using any fields of the database and the results can be put into tables and printed or exported and saved in other files. (author)

    2001-01-01

    We have developed in this thesis a methodology of integrated characterization of heterogeneous reservoirs, from geologic modeling to history matching. This methodology is applied to the reservoir PBR, situated in Campos Basin, offshore Brazil, which has been producing since June 1979. This work is an extension of two other thesis concerning geologic and geostatistical modeling of the reservoir PBR from well data and seismic information. We extended the geostatistical litho-type model to the whole reservoir by using a particular approach of the non-stationary truncated Gaussian simulation method. This approach facilitated the application of the gradual deformation method to history matching. The main stages of the methodology for dynamic data integration in a geostatistical reservoir model are presented. We constructed a reservoir model and the initial difficulties in the history matching led us to modify some choices in the geological, geostatistical and flow models. These difficulties show the importance of dynamic data integration in reservoir modeling. The petrophysical property assignment within the litho-types was done by using well test data. We used an inversion procedure to evaluate the petrophysical parameters of the litho-types. The up-scaling is a necessary stage to reduce the flow simulation time. We compared several up-scaling methods and we show that the passage from the fine geostatistical model to the coarse flow model should be done very carefully. The choice of the fitting parameter depends on the objective of the study. In the case of the reservoir PBR, where water is injected in order to improve the oil recovery, the water rate of the producing wells is directly related to the reservoir heterogeneity. Thus, the water rate was chosen as the fitting parameter. We obtained significant improvements in the history matching of the reservoir PBR. First, by using a method we have proposed, called patchwork. This method allows us to built a coherent model from various parts of a set of models. Then, starting with the model obtained by patchwork, we used the regionalized gradual deformation method for further improve the history matching. (author)

    Eddy current tomography can be employed to caracterize flaws in metal plates in steam generators of nuclear power plants. Our goal is to evaluate a map of the relative conductivity that represents the flaw. This nonlinear ill-posed problem is difficult to solve and a forward model is needed. First, we studied existing forward models to chose the one that is the most adapted to our case. Finite difference and finite element methods matched very good to our application. We adapted contrast source inversion (CSI) type methods to the chosen model and a new criterion was proposed. These methods are based on the minimization of the weighted errors of the model equations, coupling and observation. They allow an error on the equations. It appeared that reconstruction quality grows with the decay of the error on the coupling equation. We resorted to augmented Lagrangian techniques to constrain coupling equation and to avoid conditioning problems. In order to overcome the ill-posed character of the problem, prior information was introduced about the shape of the flaw and the values of the relative conductivity. Efficiency of the methods are illustrated with simulated flaws in 2D case.

    Full Text Available “AIR TEMPERATURE DATA IN POARTA LUI IONEL CAVE (BIHORMOUNTAINS, ROMANIA”. The authors analyzed the one-year temperature cycle values continuously registered in Poarta lui Ionel Cave by using five data loggers. Pursuant to the distinctive cave morphology, the big gallery that forms the basal level is under a permanent bidirectional ventilation effect, while the upper gallery is characterized by an obvious stability. According to the dynamics of air exchanges, theoutside influences are strong enough, so that to the cave temperature vary during a year period with an evident periodicity, not only seasonal, but also daily. In spite of the lack of a similar periodicity, the daily amplitudes are quite important, exceeding 1°C in the extremity of the basal gallery. These facts mean that, beside the convection phenomena, the outside influences can also propagate in the cave by conduction.

    Reflection tomography can determine velocity models containing lateral velocity variations and reflectors of arbitrary shapes; in order to access the kinematic data, a 3D zero offset approach to the SMART (Sequential Migration Aided Reflection Tomography) method, an original method of migration velocity analysis, is adopted. The approach involves interpreting kinematic data in the post-stack depth migrated cube and then de-migrating the horizons by two-point ray-tracing. A fast and robust two-point ray-tracer is developed, which can recover multi-valued kinematic data from complex geological structures. An original formulation for 3D reflection tomography is proposed, which can reliably take into account multivalued travel times

    In power generation plants, rotating machines are involved in energy transformation processes and safety systems. The bearings supporting the rotors and the thrust bearings play a crucial role in the reliability of these machines. The phenomena encountered straddle several disciplines: hydrodynamics, tribology, thermomechanics, materials and vibrations in a specific environment, namely: thin fluid film, solid mechanical components and shaft rotation. Means of analysing the behaviour of these components (bearings and thrust bearings) have been developed and implemented. These consists of the EDYOS (Etude Dynamique des Organes de Supportage) code for dynamically studying bearing devices and several related bench tests. In reality, in order to understand the complex physical phenomena encountered in these components, it is vital to carry out analyses and experimental validations. Since these investigations cannot be carried out on actual machines, test benches have been built which can subject the sample bearings to the equivalent stresses. (author) 14 figs.

For this, we analyze 38 retail segment agencies, of a single national institution, which is ranked as one of the largest Brazilian banks. The results show the Multicriterial Performance Index - IDM, which represents the consolidated index of multicriterial performance of each agencies under analysis, considering the fi nancial, the operational, the customer and the staff performance perspectives. We can see, yet, at the 10 % level of signifi cance, that the performance is related to the size of agencies, because the average multicriterial performance of 10 major agencies is higher than the 10 smaller agencies. This refl ects the scale economies that exist in the operations of agencies.

Essas informações podem ser de natureza econômica, financeira, física e de produtividade, e devem possibilitar uma adequada avaliação da situação atual do empreendimento, assim como oferecer subsídios para progn6sticos. O instrumental utilizado e composto basicamente por demonstrações contábeis tradicionais e por algumas informações suplementares, geralmente divulgadas em notas explicativas, relatório da administração e parecer dos auditores independentes. Alguns autores entendem que evidenciação é um principio contábil, outros entendem que e um objetivo, mas, nos diversos pronunciamentos, torna-se claro que evidenciação e mais do que um principio, a uma espécie de ligação entre os postulados, os princípios contábeis e os objetivos da contabilidade. E um meio para se atingir os objetivos da contabilidade. Nesse contexto, identificamos uma forte ligação entre disclosure - ou evidenciação - e o objetivo principal da contabilidade: as informações divulgadas devem ser transparentes e úteis ao processo de tomada de decisões. Para se definir o que e útil, faz-se necessário uma constante interação com o usuário da informação contábil, de modo a poder oferecer um produto que atenda as suas necessidades, constantemente alteradas face à dinâmica do próprio mercado e em decorrência do processo de globalização. Com isso, a demanda por demonstrações contábeis, assim como sua grande importância, cresce a uma taxa acelerada, requerendo um dinamismo semelhante na evolução da qualidade da informação fornecida.

    Full Text Available This paper aimed to investigate the influence organizational values at bank branches have on bank branchperformance. The research was undertaken at branches of a Brazilian publicly held bank. The questionnairecalled Inventário de Perfis de Valores Organizacionais (IPVO, or Inventory of Organizational Values Profileswas adapted to measure the organizational values of bank branches. Bank branch performance was measuredobjectively, using the percentage of goals accomplished during the year 2009. The sample is non-probabilisticand is formed by 271 bank branches and the data about the organizational values of bank branches was providedby 720 respondents. Data analysis revealed that the organizational values of bank branches are organized intofour factors: respect for stakeholders, employee entertainment, competent performance, and prestige. Prestige ispositively correlated with bank branch performance, and respect for stakeholders and employee entertainmentare negatively correlated with the dependent variable. The multiple regression analysis yielded an equation thataccounts for 9.5% of the variance in performance and contains two factors as independent variables whichpositively influence bank branch performance: prestige and competent performance. The results showed thatorganizational values are one of the variables that can impact bank branch performance.

    Petit, J.L.

    1997-07-21

    This thesis is devoted to the inversion of VSP (vertical seismic profile) seismic data in order to determine the elastic properties of horizontally stratified media. The VSP records are computed using the full wave elastic modelling in isotropic and transversely isotropic media using Hankel transform, a finite difference scheme and an inverse Hankel transform algorithm, and the propagation equations are determined and numerically solved; the importance of considering a 3D wave propagation model instead of a 1 D one is emphasized. The theoretical VSP inverse problem is then considered, with the seismic waveform inversion set as a least-squares problem, consisting in recovering the distribution of physical parameters which minimize the misfit between calculated and observed VSP. The corresponding problem requires the knowledge of the source function

    Ruiz Paredes, J.A

    2007-05-15

    In order to make the broadband kinematic rupture modeling more realistic with respect to dynamic modeling, physical constraints are added to the rupture parameters. To improve the slip velocity function (SVF) modeling, an evolution of the k{sup -2} source model is proposed, which consists to decompose the slip as a sum of sub-events by band of k. This model yields to SVF close to the solution proposed by Kostrov for a crack, while preserving the spectral characteristics of the radiated wave field, i.e. a w{sup 2} model with spectral amplitudes at high frequency scaled to the coefficient of directivity C{sub d}. To better control the directivity effects, a composite source description is combined with a scaling law defining the extent of the nucleation area for each sub-event. The resulting model allows to reduce the apparent coefficient of directivity to a fraction of C{sub d}, as well as to reproduce the standard deviation of the new empirical attenuation relationships proposed for Japan. To make source models more realistic, a variable rupture velocity in agreement with the physics of the rupture must be considered. The followed approach that is based on an analytical relation between the fracture energy, the slip and the rupture velocity, leads to higher values of the peak ground acceleration in the vicinity of the fault. Finally, to better account for the interaction of the wave field with the geological medium, a semi-empirical methodology is developed combining a composite source model with empirical Green functions, and is applied to the Yamaguchi, M{sub w} 5.9 earthquake. The modeled synthetics reproduce satisfactorily well the observed main characteristics of ground motions. (author)

    Baroni, A.

    1996-11-20

    Simulation of a cross-well experience is difficult, due to the generation of guided waves in the source containing well and in the receiver containing well. A hybrid sub-structural technique is proposed for the experience modelling, where the two holes are independently considered, using analytical and numerical approaches. The unknown quantity of the global problem, describing the global interaction between all the domains, is the stress vector applied on all the interfaces; this problem requires the solution of local problems describing local equilibrium in each domain. The boundary integral equation method in elastic domains, and a variational formulation in fluid domains, are used, assuming the existence of the zeroth guided mode, known as tube wave, at the fluid-solid interface

    3D VSP imaging is nowadays a strategic requirement by petroleum companies. It is used to precise in details the geology close to the well. Because of the lack of redundancy and limited coverage in the data. this kind of technology is more restrictive than surface seismic which allows an investigation at a higher scale. Our contribution was to develop an elastic quantitative imagine (GRT migration) which can be applied to 3 components borehole dataset. The method is similar to the Kirchhoff migration using sophistical weighting of the seismic amplitudes. In reality. GRT migration uses pre-calculated Green functions (travel time. amplitude. polarization). The maps are obtained by 3D ray tracing (wavefront construction) in the velocity model. The migration algorithm works with elementary and independent tasks. which is useful to process different kind of dataset (fixed or moving geophone antenna). The study has been followed with validations using asymptotic analytical solution. The ability of reconstruction in 3D borehole survey has been tested in the Overthrust synthetic model. The application to a real circular 3D VSP shows various problems like velocity model building, anisotropy factor and the preprocessing (deconvolution. wave mode separation) which can destroy seismic amplitudes. An isotropic 3 components preprocessing of the whole dataset allows a better lateral reconstruction. The choice of a big migration aperture can help the reconstruction of strong geological dip in spite of migration smiles. Finally, the methodology can be applied to PS converted waves. (author)

    This work studies the seismic behaviour of fast neutrons reactor cores. It consists in analyzing the tests made on the models Rapsodie and Symphony by using the calculation code Castem 2000. Te difficulty is in the description of connections of the system and the effects of the fluid (calculation in water). The results for the programme Rapsodie are near the experimental results. For the programme Symphony, the calculations in air have allowed to represent the behaviour of fuel assemblies in a satisfying way. It is still to analyze the tests Symphony in water. (N.C.)

    Diagenetic minerals frequently damage reservoir permeability. A numerical model which couples chemical reactions and transport of dissolved elements can help to predict both location and magnitude of cementations. The present Ph.D. examines how can be applied such a modelling approach to a complex heterogeneous reservoir. Petrographical data from core samples are used as input data, or alternatively as controls for validating the modelling results. The measurements, acquired with dm-to-m spacing are too numerous to be integrated in a reactions-transport code. The usual up-scaling methods, called Homogenization, conserve only the fluid flow properties. A new method, called `Gathering` takes into account material transport balance. It is proposed in the first part of the dissertation. In the second part, an application of Gathering is done simulating illitization in the sub-arkosic sandstones of the Ness formation (Brent Group) in a North Sea field, Dunbar.. As a prerequisite, data accuracy is examined for a set of `routine measurements` (100 points counting on thin section, XR-diffractometry and gas porosity/permeability). (author) 60 refs.

    1999-03-09

    The work of this thesis is to study and to solve a shape inversion problem in petroleum reservoir engineering. We developed history matching methods of production data such as well measurements in order to better identify the geometry of geological bodies in a reservoir. Fluid flows are single phase or multiphase. The numerical simulation of these flows is based on a finite volume method on structured meshes. In this context, classical shape optimisation techniques based on mesh perturbations can not be applicable. In fact, each time the surface describing the region to optimize crosses a new grid mesh, the discrete problem gets non differentiable. In order to overcome the difficulty, some authors propose very expensive optimisation methods that only need evaluations of the criterion to be minimized. In this thesis, we propose an approach that consists in working on the continuous problem that is differentiable. In our problem, we generally work a great number of parameters. For this reason, the adjoint state method has been used to calculate the derivative of the cost function with respect to the geometry. Then, it allowed us to calculate rapidly the gradients by discretization of the derivative obtained and to elaborate inversion. processes based on classical algorithms of optimisation. During this thesis, we also pointed out the possibility to modify the topology of the domain using the idea of topological gradient. The development of this topological optimisation method was made possible thanks to the efficiency of the adjoint state method. The adaptation cost of the results was small, especially for the calculation of the sensitivities with respect to the position of small size obstacles. The proposed applications concern the identification of the thickness and the width of channels of the position and the size of faults, of top surface and reservoir limits. An example of application of topological optimisation was performed with geostatistical models including a very strong change of topology. The obtained results are promising. (author) 47 refs.

    Granite and gneiss sampled from the submarine fault scarps of the Sardinia Channel were dated using the apatite fission-track method. One sample provides an age of 22.8 {+-} 1.3 Ma, which is in the range of the cooling ages of the Calabrian-Peloritan basement, where cooling is due to erosion. Three other samples have ages around 10 Ma, probably due to a tectonic denudation during the Tortonian extension in the Sardinia Channel. (authors)

    Wind energy is a component of an energy policy contributing to a sustainable development. Last years, offshore wind parks have been installed offshore. These parks benefit from higher wind speeds and lower turbulence than onshore. To sit a wind park, it is necessary to have a mapping of wind resource. These maps are needed at high spatial resolution to show wind energy resource variations at the scale of a wind park. Wind resource mapping is achieved through the description of the spatial variations of statistical parameters characterizing wind climatology. For a precise estimation of these statistical parameters, high temporal resolution wind speed and direction measurements are needed. However, presently, there is no data source allying high spatial resolution and high temporal resolution. We propose a data fusion method taking advantage of the high spatial resolution of some remote sensing instruments (synthetic aperture radars) and the high temporal resolution of other remote sensing instruments (scatterometers). The data fusion method is applied to a case study and the results quality is assessed. The results show the pertinence of data fusion for the mapping of wind energy resource offshore. (author)

    Full Text Available During its operating period, the ICESat lidar satellite collected data on the surface of the earth between 80 ° and -80 ° latitude. It allowed us to have several points of altimetry measurements on Lake Tsimanampetsotsa on several measurement campaigns. For each campaign, we found that standard deviation of the altimetric measurements made by ICESat is low. Measurements on the lake are therefore homogeneous with averages ranging from 4.9 m to 6.8 m and standard deviations that are less than 1 m. Observing the variation over time of the mean level of Lake Tsimanampetsotsa, there is a slight downward trend in the water level. The level of the lake lost 0.60 m between 2004 to 2009.

    Object based models are very helpful to represent complex geological media such as fractured reservoirs. For building realistic fracture networks, these models have to be constrained to both static (seismic, geomechanics, geology) and dynamic data (well tests and production history). In this report we present a procedure for the calibration of large-scale fracture networks to production history. The history matching procedure includes a realistic geological modeling, a parameterization method coherent with the geological model and allowing an efficient optimization. Fluid flow modeling is based on a double medium approach. The calibration procedure was applied to a semi-synthetic case based on a real fractured reservoir. The calibration to water-cut data was performed. (author)

    This is the forty-sixth issue of the United Nations Statistical Yearbook, prepared by the Statistics Division, Department of Economic and Social Affairs of the United Nations Secretariat. It contains series covering, in general, 1990-1999 or 1991-2000, based on statistics available to the Statistics Division up to 30 November 2001. The major purpose of the Statistical Yearbook is to provide in a single volume a comprehensive compilation of internationally available statistics on social and economic conditions and activities, at world, regional and national levels, covering roughly a ten-year period. Most of the statistics presented in the Yearbook are extracted from more detailed, specialized publications prepared by the Statistics Division and by many other international statistical services. Thus, while the specialized publications concentrate on monitoring topics and trends in particular social and economic fields, the Statistical Yearbook tables provide data for a more comprehensive, overall description of social and economic structures, conditions, changes and activities. The objective has been to collect, systematize and coordinate the most essential components of comparable statistical information which can give a broad and, to the extent feasible, a consistent picture of social and economic processes at world, regional and national levels. More specifically, the Statistical Yearbook provides systematic information on a wide range of social and economic issues which are of concern in the United Nations system and among the governments and peoples of the world. A particular value of the Yearbook, but also its greatest challenge, is that these issues are extensively interrelated. Meaningful analysis of these issues requires systematization and coordination of the data across many fields. These issues include: General economic growth and related economic conditions; economic situation in developing countries and progress towards the objectives adopted for the United Nations development decades; population and urbanization, and their growth and impact; employment, inflation and wages; energy production and consumption and the development of new energy sources; expansion of trade; supply of food and alleviation of hunger; financial situation and external payments and receipts; education, training and eradication of illiteracy; improvement in general living conditions; pollution and protection of the environment; assistance provided to developing countries for social and economic development purposes

    The EDELWEISS experiment aims to detect WIMPs, hypothetical and elusive particles which could possibly amount for all or part of the dark matter in the universe. For that purpose, it uses cryogenic germanium detectors able to record both the rise in temperature and the ionisation created by a WIMP interaction in the semi-conductor crystal bulk. This thesis work focuses on the last data taking campaign of phase I of the experiment. It is centered around three main points. In a first part, we present the elaboration of a new numerical acquisition system, based on a heat channel trigger, contrary to the previous system which was based on an ionisation channel trigger. In a second part, we expose the complete analysis of the data acquired with this new system, from the calibration of each measurement channel to the extraction of a result in terms of sensitivity to a WIMP signal. Lastly, we dedicate a whole chapter to a further analysis of the high energy data, as well as to the interpretation of the different radioactive backgrounds we observe, in order to prepare the next phase of the experiment due to begin at the end of 2005.

    The aim of this work was to evaluate how much integral slab experiments can both reduce discrepancies between experimental results and calculations, and improve the knowledge of hafnium isotopes neutronic parameters by an adapted sensitivity and uncertainty method. A statistical approach, based on the generalized least squares method and perturbation theory, has been incorporated into our calculation system in order to deduce microscopic cross-section adjustments from observed integral measurements on this particular 'mock-up' reactor.In this study it has been established that the correlations between integral parameters and hafnium capture cross-sections enable specific variations in the region of resolved resonances at the level of multigroup and punctual cross-sections recommended data (JEF-2.2 evaluation) to be highlighted. The use of determinist methods together with Monte Carlo- type simulations enabled a depth analysis of the modelling approximations to be carried out. Furthermore, the sensitivity coefficient validation technique employed leads to a reliable assessment of the quality of the new basic nuclear data. In this instance, the adjustments proposed for certain isotope {sup 177}Hf resonance parameters reduce, after error propagation, by 3 to 5 per cent the difference between experimental results and calculations related to this absorbent's efficiency. Beyond this particular application, the qualification methodology integrated in our calculation system should enable other basic sizing parameters to be treated (chemical / geometric data or other unexplored nuclear data) to make technological requirements less stringent.

    Ever since the discovery of the 511 keV annihilation line emission from the galactic center region in the late seventies, the origin of galactic positrons has been the topic of a vivid scientific debate. It is also one of the prime scientific objectives of the imaging spectrometer SPI on board ESA's INTEGRAL observatory. In this thesis first a description of the most important SPI sub-system is given - the detector plane. Procedures for detector energy calibration and detector degradation analysis are developed. The determination of instrumental background models, a crucial aspect of data analysis, is elaborated. These background models are then applied to deriving sky maps and spectra of unprecedented quality of the Galactic positron annihilation radiation. The emission is centered on the galactic center with a spatial resolution of 8 degrees (FWHM), a second spatial component appears clearly: the galactic disc. The ray energy has been measured with unprecedented accuracy: 511.0 {+-} 0.03 keV for a full width at half maximum (FWHM) of 2.07 {+-} 0.1 keV. The total galactic flux ranges from 1.09 to 2.43 10{sup -3} ph.cm{sup -2}.s{sup -1} including uncertainties on spatial distribution. Finally, the implications of these observations for the production of positrons by various Galactic populations are discussed.

    The prediction of oil recovery or pollutant dispersion requires an accurate knowledge of the permeability field distribution. Available data are usually measurements in well bores, and, since a few years, 4D-seismic data (seismic mappings repeated in time). Such measurements allow to evaluate fluids displacements fronts evolution. The purpose of the thesis is to evaluate the possibility to determinate permeability fields from fluid displacement measurements in heterogeneous porous media. At the laboratory scale, experimental studies are made on a model and on numerical simulations. The system uses blocks of granular materials whose individual geometries and permeabilities are controlled. The fluids displacements are detected with an acoustical. The key parameters of the study are the size and spatial correlation of the permeability heterogeneity distribution, and the influence of viscosity and gravity contrasts between the injected ant displaced fluid. Then the inverse problem - evaluating the permeability field from concentration fronts evolution - is approached. At the reservoir scale, the work will mainly be focused on the integration of 4D-seismic data into inversion programs on a 3D synthetic case. A particular importance will be given to the calculation of gradients, in order to obtain a complementary information about the sensitivity of data. The information provided by 4D-seismic data consists in maps showing the vertical average of oil saturation or the presence of gas. The purpose is to integrate this qualitative information in the inversion process and to evaluate the impact on the reservoir characterization. Comparative studies - with or without 4D-seismic data - will be realized on a synthetic case. (author)

  13. Potentiel des donnees AMSR-E et RADARSAT-2 pour le suivi des cycles de gel/degel du sol dans des zones agricoles au Canada

    Science.gov (United States)

    B-Rousseau, Louis-Philippe

    Soil freezing and thawing processes are of particular importance for agricultural areas. For example, frozen soils can increase the runoff during snowmelt in the spring. Freezing and thawing also have a direct influence on the sowing and harvesting dates, as well as on the crop yield. A better understanding of those phenomena is therefore important, and several researchers focused on this topic in the past. Due to its sensitivity to changes in the state of water, microwave remote sensing is an appropriate tool for that purpose. The main objective of this study is to monitor soil freezing and thawing processes using AMSR-E and RADARSAT-2 polarimetric data acquired over an agricultural area located near Saskatoon (Saskatchewan). With AMSR-E data, the goals are to compare different combinations of frequencies for the spectral gradient's algorithm regarding their capacity for detecting frozen soils, and to analyze the temporal dynamics of the brightness temperature in order to find a new indicator of soil freezing. As for RADARSAT-2 data, several polarimetric parameters and techniques are tested in order to identify soil freezing. For the first part concerning AMSR-E data, a global precision for the discrimination of frozen and thawed soils higher than 90% was obtained with the spectral gradient's algorithm, for the combinations including high (18.7 and 36.5 GHz) and low (6.9 and 10.7 GHz) frequencies as well as for the one using only high frequencies. It is shown that, for the combination based on the 18.7 and 36.5 GHz frequencies, results are improved when a negative threshold is used for the spectral gradient. When high and low AMSR-E frequencies are combined, a null threshold is on the contrary appropriate, which constitutes an operational advantage. A new algorithm for detecting frozen soils, based on a thresholding approach applied to the spectral gradient of polarization difference and the brightness temperature at 36.5 GHz, was also proposed. The performances of the new algorithm to discriminate frozen and thawed soils are very similar to those obtained using the spectral gradient of brightness temperature (global precision around 90% and probability of detecting frozen soils between 70% and 85%). The performances are also slightly higher for the combinations including the lower AMSR-E frequencies. However, annual statistics for the spectral gradient of polarization difference are required to calculate the thresholds. The results obtained with AMSR-E data highlight the relevance of including SMOS L-band brightness temperatures for the calculation of brightness temperature and polarization difference spectral gradients. The qualitative analysis of the results obtained using RADARSAT-2 data shows that surface scattering dominates volume scattering for frozen soils, which can be explained by the rough fields in the study area, as compared to the signal's wavelength (C-band). Nevertheless, several polarimetric parameters indicate a slight increase of the volume scattering in frozen soils, which is theoretically expected. This was observed for the linear and circular depolarization ratios, the amplitude of the HHVV, RLLL and RLRR correlation coefficients, as well as for the pedestal height. Also, the entropy and α-angle of the Cloude-Pottier target decomposition increase slightly in frozen soils ; the same is true for the volume scattering component of the Freeman-Durden and Yamaguchi target decompositions, with an equivalent decrease of the surface scattering component. Despite these interesting observations, a quantitative analysis of the results is necessary in order to evaluate the usefulness of polarimetry regarding the detection of frozen soils. This would allow the validation of the behavior, possibly caused by soil freezing, of the mean value and the standard deviation of the HHVV phase difference and the standard deviation of the RLLL and RLRR phase differences.

    The forward-looking analysis of systems failure consists in identifying the conditions that may lead to failures and to foresee their consequences on the reliability, maintainability, availability and safety of systems at the design stage or at the operation stage. It is performed from various information, the selection and analysis of which allows to design a system model. The essential information is: a description of the real system (physical and functional structures), the characteristics of the system components and of the interactions between them (failure modes and their consequences), the relations between the system and its environment, and the consideration of human errors at the exploitation step. Content: 1 - steps of an operation safety analysis; 2 - functional analysis methods: FAST, RELIASEP, SADT, IDEFO, APTE and other methods; 3 - Forward-looking analysis methods: qualitative methods, mixed and quantitative methods, human factors; 4 - reliability databases.

    Sturge-Weber syndrome (SWS) is a rare congenital sporadic disease with neuro-ocular and cutaneous vascular findings. Clinically, the full-blown condition consists of a facial port-wine stain (PWS) the V1 facial trigeminal skin area, alone or in combination with V2 and V3 PWS, seizures and ocular abnormalities (glaucoma and choroidal angioma). Radiologically, a leptomeningeal (pial) capillary and venous malformation, mostly located in the parieto-occipital area, cerebral atrophy and calcifications are demonstrated. An ipsilateral enlarged choroid plexus may be an early anatomic symptom. Development neuro-diagnostic technique for the screening of infants with an at-risk V1 PWS, as well as for the follow-up of patients with evidence SWS. Accelerated myelination in the involved hemisphere may be early diagnostic feature before 6 months of age. Later, hyperintensity of white matter on T2 is considered a symptom of gliosis. Clinically, progression of the diseases is associated with anatomic changes and correlates with the extent of the pial vascular anomaly, extent and severity of cerebral atrophy, and white matter abnormalities. A neonatal neuro-imaging work-up, using CT or MRI, may not demonstrate the pial anomaly and should be repeated after 6 to 12 months in an at-risk infant with V1 PWS. (authors)

    The topic of this study was to put to the fore, thanks to our electron spin resonance experiments, one charge transfer process, which was optically induced between the deep donor As{sup +}{sub G}a and the different acceptors, which were present in the material. We described these processes through a theoretical model, which we named charge transfer model. With this latter, we were able to trace a graph network, representing the As{sup +}{sub G}a concentration kinetics. Then we verified the compatibility of our model with one transport experiment. One experimental verification of our model were delivered, thanks to neutronic transmutation doping. The following stage was the study of defects, induced by thermal strains, to which the crystal was submitted during the cooling phase. At last we wanted to get round the non solved super hyperfine structure problem for GaAs by studying another III-V material for which she was resolved, namely gallium phosphide.

  20. Detection automatique des changements du bati en milieu urbain sur des images a tres haute resolution spatiale (Ikonos et QuickBird) en utilisant des donnees cartographiques numeriques

    Science.gov (United States)

    Bouziani, Mourad

    The updating of cartographic databases in urban environments is a difficult and expensive task. It can be facilitated by an automatic change detection method. Several methods have been developed for medium and low spatial resolution images. These methods are not adapted for the very high spatial resolution images (VHSR) and are not applicable in urban environment. This study proposes a new method for change detection of buildings in urban environments from VHSR images and using existing digital cartographic data. The proposed methodology is composed of several stages. The existing knowledge on the buildings and the other urban objects are first modelled and saved in a knowledge base. All change detection rules are defined at this stage. Then, the image is segmented. The parameters of segmentation are computed thanks to the integration between the image and the geographical database (GDB). Thereafter, the segmented image is analyzed using the knowledge base to localize the segments where the change of building is likely to occur. The change detection rules are then applied on these segments to identify the segments that represent the changes of buildings. These changes represent the updates of buildings to add to the geographical database. Finally, the map representing changes is assessed before being integrated in the geographical database. The data used in this research concern the city of Sherbrooke (Quebec, Canada) and the city of Rabat (Morocco). For Sherbrooke, we used an Ikonos image acquired in October 2004, an Ikonos image acquired in July 2006 and a GDB at the scale of 1:20,000. For Rabat, a QuickBird image acquired in August 2004 has been used with a GDB at the scale of 1:10,000. The results of tests on several zones are encouraging. Indeed, the rate of good detection is of 90%. Concerning the geometric precision of detection, the mean error is 3 m for Ikonos and 2 m for QuickBird. The proposed method presents some limitations on the detection of the exact contours of the buildings. It could be improved by including a shape post-analysis of detected buildings. The proposed method can be integrated in a cartographic update process or as a method for the quality assessment of a topographic database.

    In this paper we describe a new method to obtain estimations of the geostatistical parameters (GPs) such as the correlation length, l{sub c} and the permeability variance, {sigma}{sub ln}{sup 2} from well test data. In practical studies, the GPs are estimated using geological and petrophysical data, but often, these data are too scarce to give precise results. The proposed method uses the Bayesian inversion theory, in conjunction with a fast evaluation of well tests that implies up-scaling techniques. The method was tested using synthetic well-test data performed on some training images, and estimations of the underlying correlation length, l{sub c} and permeability variance, {sigma}{sub ln}{sup 2} were recovered. These estimations give a correct order of magnitude of the actual values, but as noticed in similar methods, the uncertainties are high. Once the GPs are estimated, other well established techniques can be used to get well-test matched reservoir images consistent with the geostatistical model. We will see that excellent well test data are needed, and that the method could be improved using multiple well test data. (authors)

    Full Text Available A análise de desempenho de uma organização é sempre algo passível de muitas discussões. Questionamentos sobre quais indicadores utilizar e como consolidá-los de forma a estabelecer um critério justo de avaliação de performance estão presentes em vários estudos e no dia-a-dia das empresas. É nesse sentido que se apresenta este trabalho como uma proposta de modelagem deste problema, por intermédio da utilização da Análise Envoltória de Dados (DEA. Busca-se um índice de performance relativa que seja capaz de conjugar indicadores financeiros de liquidez, de custo, de risco e de rentabilidade na análise de desempenho organizacional. Em outras palavras, o índice de cada empresa é uma combinação integrada de vários vetores de desempenho e é função não só de sua performance, mas também do desempenho das outras empresas analisadas. Fizeram parte da amostra desta pesquisa bancos de quatro segmentos: 20 bancos de varejo, 34 de atacado, 21 de middle market e 26 de financiamento, que estavam em operação no Brasil em 2003, listados no ranking da revista Balanço Financeiro da Gazeta Mercantil, sobre o desempenho dos melhores bancos e outras instituições financeiras. Os resultados mostram que tanto os gigantes quanto as pequenas e médias instituições têm totais condições de sobrevivência e de competição, pois não é o tamanho que gera a competitividade no setor, mas sim o desempenho superior.

As observações e conclusões apresentadas resultam da análise de um estudo de caso que teve como objeto um banco estatal em vias de privatização, bem como da utilização de estatísticas gerais sobre o setor. Dentre as conclusões, caberia destacar que os ganhos para a força de trabalho, resultantes do processo em estudo, poderiam ser relativizados, já que os mesmos são acompanhados de efeitos negativos, como maior desgaste físico e mental da força de trabalho, além da ocorrência de altas taxas de desemprego. Nesse sentido, conclui-se que, a uma possível elevação da qualificação dos que permanecem no emprego, corresponderia uma degradação das condições de vida em termos mais gerais.The article aims to raise some issues related to the restructuring process in the banking sector and its social implications (employment, skills, training, wage and union's action, in the context of the 1990's. The observations and conclusions presented result from the analysis of a case-study in a Brazilian state bank preparing for privatization, as well as from the use of statistics concerning the sector as a whole. Among the conclusions, it is worth to mention that the gains obtained by the work-force in the process under study should be assessed vis-à-vis the negative effects as physical and mental stress for those who remain employed, as well as the occurrence of high rates of unemployment. The main conclusion, therefore, would be that the skills raising in employment would correspond to a degradation of living conditions in general.

    Probing the matter in order to check its elementary constituents, that is the goal of the particle physic. In this field, the experiments consist in colliding highly energetic particle beams and observing the new born particles. These observations are based on big particle detectors whose running is dependant on the precise knowledge of their geometry (position of the detection chambers). To achieve this, the detectors are equipped with alignment sensors, which have to be calibrated before. This document describes the study and the making of a calibration bench for the 'Praxial' (PRoximity AXIAL) type sensors, and other works related to these sensors. In a first part, we determine and apply a method to set the tools used to fix the sensor stands on the detection chambers. These settings are made with the use of a tridimensional measuring machine. Then, we study the stands themselves. These investigations concern mechanics: positioning quality of the sensors in their stands, bending of the supports due to the tightening. In this part too, the studies are in the field of dimensional metrology. After this, the works are reoriented toward the bench, with the choice of the displacement sensors among two different technologies: optical, with the Rasnik system, and mechanical, with linear probes as LVDT (Linear Variable Differential Transformer). Following the discovery of an ambiguity on the Rasnik system, we go on the tests to understand its behaviour. We introduce the theory of the alignment sensors calibration, which is based on a minimization calculation. The computer programs are explained in a chapter, and in an other, the implementation of the quality assurance procedures. An other part describes the mechanical studies and the problems they cause. Because of a delay onset of the project, we make a model of the bench. This dummy allows us to test every single function of the final bench. With this device, we record manually the first calibration data and use them as input of the minimization program. (author)

    Full Text Available Public banks are an important part of the banking market in Brazil and abroad, and they have been used to implement strategies furthering political and social goals. Although one of the main arguments for the existence of public banks is to encourage competition, this role remains controversial in literature. This paper analyzes the Brazilian banking market during the period from 2000 to 2011, calculating the level of competition between private and public banks, and their reactions to the measures adopted by the Brazilian government during the world crisis of 2008, when the government adopted a policy of publicly influencing public banks to increase loan approvals and reduce interest rates. From results obtained through three stage least squares estimation of the Lerner index, we found that public banks exhibit behavior closer to perfect competition than private banks, even though they can exert some market power.

    Full Text Available O caso em estudo mostra a comparação entre dois modelos de serviços logísticos de um banco que decidiu terceirizar, em 2012, as atividades de apoio, serviço logístico expresso de entrega de cartões, malotes e documentos registrados, dentre outros, para um operador logístico. O método de pesquisa é quali-quantitativo, por intermédio de entrevista semiestruturada e observação participante na instituição pesquisada.  Os resultados mostraram, por meio de indicadores de desempenho de processo, a situação do período anterior à terceirização em 2011; posteriormente, avaliou-se o processo terceirizado, em 2012, que não obteve o resultado esperado pelo banco e, por fim, analisou-se o período de 2013, considerando o novo operador logístico e, dessa vez, mostrou-se um caso de sucesso. Um aspecto relevante deste estudo é mostrar a importância de se implementar indicadores de desempenho para o controle do processo para a tomada de decisão no que tange a melhorias e alinhamento dos objetivos do negócio, além de considerar nas decisões de terceirização os ganhos financeiros, levar em conta o aspecto estratégico da operação.

    RESUMO

    O objetivo deste artigo é analisar o entendimento dos funcionários de um grande banco brasileiro sobre o tema intraempreendedorismo, bem como sua aplicabilidade à empresa. Para tanto, foram efetuadas 19 entrevistas com gestores, executivos e funcionários da organização estudada. Como resultado, verificou-se que o termo intraempreendedorismo ainda é pouco conhecido na empresa, muito embora os conceitos e fundamentos ligados ao termo sejam compreendidos. A existência de diversos programas institucionais relacionados ao intraempreen-dedorismo é um forte indício de que a empresa busca valorizar e atrair cada vez mais funcionários com perfil intraempreendedor. Contudo, o entendimento sobre essas iniciativas organizacionais não é homogêneo entre as áreas. Verificou-se também que o incentivo e reconhecimento ao profissional intraempreendedor ainda é muito dependente de ações individuais dos gestores diretos.

    In the domain of thermal engineering, new materials have been developed which are characterized by a high thermal diffusivity (5 to 10 times greater than the best usual conductors: gold, copper, silicon..) but also by a small thickness (from few hundreds of microns to few microns). Their time of response is very short (some few milliseconds to some few microseconds) and they are mainly used as heat dissipating materials. The classical thermal diffusivity measurement techniques are unable to analyze the thermal properties of these materials. Therefore, a bench for fast thermal diffusivity measurements has been developed that uses a laser system for the excitation and for the measurement of temperature (infrared detector). In this study, the measurement bench is described and the metrological problems encountered are discussed. (J.S.) 10 refs.

  19. Trace Pair Filtering for Separation of Upgoing and Downgoing Waves in Vsp (Vertical Seismic Profile Filtrage à deux canaux pour la séparation des ondes montantes et descendantes en PSV (Profil Sismique Vertical

    Full Text Available Most multichannel algorithms used for separation of upgoing and downgoing waves in VSPs assume depth-stationarity of the signal on all the traces used in the separation filter. However, if the depth-window of the filters becomes too large (100-200 m signal stationarity cannot be assumed. On the other hand, stationarity is a physically reasonable assumption for two neighbouring probe locations (5-20 m. A comparison is made of three algorithms used for the separation of upgoing and downgoing waves, that require only two adjacent traces and their first arrival times. They are independent of in-depth trace-spacing, provided there are no geological discontinuities between adjacent traces. The first approach (near-theoretical solution operates in the frequency domain. A system of two equations and two unknowns is solved for every frequency within the best coherencebandwidth. The second approach (simple solution is a delay-and-sum, and subtraction filter based on the semblance of the signals. The third approach (Wiener solution uses a Wiener filter to predict the strongest wave, which is generally the downgoing wave. The upgoing wave is then obtained by subtracting the estimated downgoing wave from the full wave record. A second application of the Wiener filter on the upgoing waves can enhance them. The near-theoretical solution and the simple solution are narrow-pass velocity filters and are applicable to zero-offset VSPs. The simple solution is suitable for noisy data. When the signal-to-noise ratio is high, the best results are obtained using the near-theoretical solution. The velocity-filter bandwidth can be increased in the Wiener solution, so that it can also be used in case of dipping reflectors or offset VSPs. The Wiener solution is suitable for noisy data, and its effectiveness can be increased by using a reference trace. The performance of these algorithms on synthetic and field data is evaluated in terms of signal-to-noise ratio, detection of upgoing waves and sensitivity to first arrival time estimates. La plupart des algorithmes utilisés pour la séparation des ondes montantes et descendantes en PSV font l'hypothèse que le signal est stationnaire en fonction de la profondeur sur toutes les traces utilisées dans le filtre de séparation. Cependant, le signal ne peut plus être supposé stationnaire lorsque les filtres sont appliqués sur une fenêtre en profondeur trop grande (100-200 m. Par contre, la stationnarité du signal peut être considérée comme une hypothèse physiquement raisonnable pour deux positions voisines de la sonde (5-20 m. Cet article présente trois algorithmes pour la séparation des ondes montantes et descendantes, qui ne nécessitent que deux traces adjacentes et les temps de première arrivée sur chacune des traces. Dans la mesure où il n'existe pas de discontinuités géologiques entre ces traces, les algorithmes sont indépendants de la distance en profondeur entre traces. Le premier algorithme (solution pseudo-théorique travaille dans le domaine fréquentiel. La séparation des ondes est obtenue par résolution d'un système de deux équations à deux inconnues pour chaque fréquence. Cette opération est effectuée dans la bande passante correspondant à la meilleure cohérence. Le second algorithme (solution simple réalise une addition et soustraction, basées sur la semblance des signaux, des traces décalées en temps. Le troisième algorithme (solution de Wiener utilise un filtre de Wiener pour prédire le champ d'ondes le plus énergique, qui correspond généralement aux ondes descendantes. Les ondes montantes sont ensuite obtenues par soustraction des ondes montantes estimées, au champ d'ondes total. Le filtre de Wiener peut être ensuite de nouveau appliqué aux ondes montantes de façon à les renforcer. La solution pseudo-théorique et la solution simple réalisent des filtres en vitesse apparente de bande passante étroite, et sont applicables aux PSV sans déport. La solution simple est bien adaptée aux données bruitées. Lorsque le rapport signal sur bruit est bon, les meilleurs résultats sont obtenus avec la solution pseudo-théorique. La bande passante du filtre en vitesse apparente peut être élargie dans la solution de Wiener. En conséquence, cet algorithme peut être également utilisé en cas de réflecteurs pentés ou de PSV avec déport. La solution de Wiener est bien adaptée aux données bruitées, et son efficacité peut être augmentée par l'utilisation d'une trace de référence. La performance de ces algorithmes sur données synthétiques et réelles est évaluée en termes de rapport signal sur bruit, de détection des ondes montantes et de sensibilité à la précision de temps de première arrivée.

    2001-06-01

    Complementary to the recording of compressional (P-) waves, the observation of P-S converted waves has recently been receiving specific attention. This is mainly due to their tremendous potential as a tool for fracture and lithology characterization, imaging sediments in gas saturated rocks, and imaging shallow sediments with higher resolution than conventional P-P data. In a conventional marine seismic survey, we cannot record P-to-S converted-wave energy since the fluids cannot support shear-wave strain. Thus, to capture the converted-wave energy, we need to record it at the water-bottom casing an ocean-bottom cable (OBC). The S-waves recorded at the seabed are mainly converted from P to S (i.e., PS-waves or C-waves) at the subsurface reflectors. The most accurate way to image seismic data is pre-stack depth migration. In this thesis, I develop a numerically efficient 2.5-D true-amplitude elastic Kirchhoff pre-stack migration algorithm designed to handle OBC data gathered along a single line. All the kinematic and dynamic elastic Green's functions required in the computation of true-amplitude weight term of Kirchhoff summation, are based on the non-hyperbolic explicit approximations of P- and SV-wave travel-times in layered transversely isotropic (VTI) media. Hence, this elastic imaging algorithm is very well-suited for migration-based velocity analysis techniques, for which fast, robust and iterative pre-stack migration is desired. In this thesis, I approach also the topic of anisotropic velocity model building for elastic pre-stack time-imaging. and propose an original methodology for joint PP-PS migration-based velocity analysis (MVA) in layered VTI anisotropic media. Tests on elastic synthetic and real OBC seismic data ascertain the validity of the pre-stack migration algorithm and velocity analysis methodology. (author)

    Full Text Available La notion d'atténuation acoustique est séparée en deux types, à savoir l'atténuation intrinsèque, liée au milieu poreux et à ses fluides saturants et l'atténuation extrinsèque liée à la géométrie du milieu poreux. La seule notion d'atténuation intrinsèque est examinée en détail sous le terme générique d'atténuation. II est montré que l'ensemble des définitions envisagées sont équivalentes dans le cas de faibles ou moyennes atténuations. Les trois paramètres les plus utilisés pour caractériser l'anélasticité d'un milieu donné sont le facteur de qualité Q, le coefficient d'atténuation alpha et le décrément logarithmiquedelta. De nombreuses méthodes existent pour mesurer pratiquement cette atténuation. Deux grandes familles peuvent être distinguées, à savoir les méthodes utilisant des systèmes vibrants ou cycliques et les méthodes utilisant des propagations d'ondes. Chacune de ces familles est étudiée en détail en insistant particulièrement sur le domaine fréquentiel d'application et la possibilité d'utilisation sur le terrain. The concept of acoustical attenuation is separated into two types, i. e. intrinsic attention linked to the porous medium and its saturating fluids, and extrinsic attention linked to the geometry of the porous media. The concept of intrinsic attention atone is examined in detail under the broader term of attenuation: All the definitions considered are shown to be equivalent for low or medium attenuations. The three most frequently used parameters for characterizing the anelasticity of a given medium are the quality factor Q, the attenuation coefficient alpha, and the logarithmic decrement delta.

    Full Text Available Le comportement d'une roche plus ou moins saturée est assimilé à un comportement visco-élastique linéaire. Cette théorie est examinée pour un milieu à une ou trois dimensions d'espace. Il est montré que les ondes planes se propageant dans un milieu visco-élastique linéaire sont des ondes inhomogènes c'est-à-dire des ondes pour lesquelles les plans de phase constante ne sont pas parallèles aux plans d'amplitude constante. La notion de facteur de qualité est définie en fonction de l'énergie perdue par cycle. Les calculs montrent que le facteur de qualité n'est plus seulement fonction des caractéristiques anélastiques du milieu traversé mais aussi de l'inhomogénéité de l'onde considérée, cette dépendance étant négligeable loin de l'angle critique. Enfin, il est montré l'effet du contraste d'atténuation sur les réflexions à l'interface entre deux milieux visco-élastiques. Quelques modèles importants sont examinés en détail à savoir les modèles élémentaires de ressorts et pots visqueux, le modèle de Zener et le modèle à Q-constant. Il est montré comment le modèle à Q-constant peut être considéré comme une somme de modèles de Zener, chacun d'entre eux caractérisant une inclusion particulière. The mechanical behavior of a more or less saturated rock is assumed to be linear visco-elastic. This theory is examined for a one- or three-dimensional space medium. Plane waves propagating in a linear visco-elastic medium are shown to be inhomogeneous waves, i. e. waves for which the constant-phase planes are not parallel to the constant-amplitude planes. The concept of quality factor is defined as a function of the energy loss per cycle. It is shown that the quality factor is a function not only of the anelastic properties of the medium crossed through but also of the inhomogeneity of the wave considered. This dependence is negligible far from the critical angle. The effect of attenuation contrast on reflections at the interface between two visco-elastic media is also discussed. Several important models are examined in detail, i. e. elementary models of springs and dashpots, the Zener model and the constant Q model. It is shown that the constant Q model can be considered as a stack of Zener models, with each of the latter characterizing a specific inclusion.

    This work aims at providing a contribution to the studies carried out on reservoir characterization by use of seismic data. The study mainly consisted in the use of geostatistical methods in order to model the geometry of stratigraphic units of the Golfe du Lion margin and to simulate the seismic facies from high resolution seismic data. We propose, for the geometric modelling, a methodology based on the estimation of the surfaces and calculation afterwards of the thicknesses, if the modelling of the depth is possible. On the other hand the method consists in estimating the thickness variable directly and in deducing the boundary surfaces afterwards. In order to simulate the distribution of seismic facies within the units of the western domain, we used the truncated Gaussian method. The used approach gave a satisfactory results, when the seismic facies present slightly dipping reflectors with respect to the reference level. Otherwise the method reaches its limits because of the problems of definition of a reference level which allows to follow the clino-forms. In spite of these difficulties, this simulation allows us to estimate the distribution of seismic facies within the units and then to deduce their probable extension. (author) 150 refs.

    La prediction de l'evolution du vieillissement de la batterie lithium-ion est source d'un grand defi, dans les applications liees aux vehicules electriques et hybrides. Sa meconnaissance est un risque considerable compromettant la viabilite d'un tel systeme. Invoquant les couts substantiels de la densite d'energie, liee a la degradation considerable des performances de la batterie au cours de sa duree de vie, il devient important d'en tenir compte des le processus de conception. La dependance de la strategie de controle du vehicule aux parametres de la batterie justifie aussi la necessite d'une telle prediction. Il est connu que le vieillissement, sensible aux facteurs tels que le courant, la temperature et la profondeur de decharge, a un impact considerable sur la perte de capacite de la batterie ainsi que sur l'augmentation de la resistance interne. Le premier est directement lie a l'autonomie electrique du vehicule, alors que le second mene a une surchauffe de la batterie, a une augmentation des pertes en puissance qui se manifeste par une diminution de la tension de bus. A cet egard, implique dans la conception d'un vehicule recreatif hybride branchable a trois roues, le Centre de Technologies Avancees s'interesse a l'etude du vieillissement de la batterie Li-ion pour une telle application. Pour ce faire, au contraire de la plupart des estimations empiriques de la duree de vie, basees sur des profils de decharge a courant constant, un profil de courant plus approprie pour l'application donnee, base sur un cycle de vitesse representatif de la conduite d'une motocyclette, a ete utilise. Par le biais d'un simulateur complet du vehicule, le cycle de courant a ete extrait du cycle de vitesse.

    Composite models are one of the possible extensions of the Standard Model. One of their implications, at the energy in the reach of present particles accelerators, would be the excitation of leptons. This PhD. thesis describes the search for excited leptons with the H1 detector installed on the electron-proton collider HERA in Hamburg (Germany). The data used were accumulated between 1994 and 2000 and amount to an integrated luminosity of 120 pb{sup -1}. The analysis of 6 different topologies were done and cover all the branching ratios of deexcitation of excited electron and neutrino. The numbers of candidates found during those analysis is in agreement with the Standard Model expectations. This means that no evidence of excited leptons production was found at HERA. This result was translated in the form of exclusion limits on the coupling of excited leptons (f/{lambda}) depending on the mass of the excited lepton. For the first time at HERA we addressed the case were the natural decay width of the excited neutrino is wider than the experimental resolution. For the first time also, a study of the variation of limit depending on the ratio f'/f was carried out. This study lead to the setting of limits independent of this ratio. The limits obtained extend results previously obtained at HEA and also the results of direct searches at LEP. (author)

    French source apportionment studies of air quality including the wood combustion source become widespread. Quantify a single source contribution to air quality requires to be provided with a specific measurable data to this source. For that reason, numerous studies have focused on the determination, in the atmospheric samples, of the source-specific compounds, usually called molecular tracers. Since 2000, trend works focused on the 'wood combustion' contribution to air quality have been based on the use of some tracers such as levoglucosan and metoxyphenols. Obtained results have been compared to atmospheric particles global characteristics: organic carbon (OC), elementary carbon (EC), PM{sub 10}, PM{sub 2.5} and polycyclic aromatic hydrocarbons (PAH). The results presented in this article show not only the interest but also the limits of such an approach, as well as the need to develop and complete the current studies in order to quantify the different sources contribution to air quality.

    This thesis takes place in the general context of calibration for industrial application. Calibration consists in assessing the values of the parameters of a model in order to simulate reality at best. This work aims at evaluating the quality of a data base by checking that the data, with respect to our objectives, 'best fill' the space. This work provides a synthesis of algorithmic and mathematic tools to achieve such a purpose. Extraction and importation techniques to improve the global quality of the data are proposed. These methods allow identifying some defaults of the data structure. An illustration of its application is exposed in the context of functional estimation with orthogonal functions. (author)

    The radio-detection of cosmic rays was first attempted in the sixties. Unfortunately at that time, the results suffered from poor reproducibility and the technique was abandoned in favour of direct particle and fluorescence detection. Taking advantage of recent technological improvements the radio-detection of ultra high energy cosmic rays is being reinvestigated. In this document, first, we remind the reader of the global problematic of cosmic rays. Then, the several mechanisms involved in the emission of an electric field associated with extensive air showers are discussed. The CODALEMA (cosmic detection array with logarithmic electro magnetic antenna) experiment that aims to demonstrate the feasibility of cosmic ray radio-detection, is extensively described along with the first experimental results. A radio-detection test experiment implanted at the giant detector Pierre Auger is presented. It should provide inputs to design the future detector using this technique at extreme energies. (author)

    Non destructive testing data from in-service inspections have specific features that require the most sophisticated techniques of signal and image processing. Each step in the overall information extraction process must be optimized by using recent approaches such like data decomposition and modelization, compression, sensor fusion and knowledge based systems. This can be achieved by means of wavelet transform, inverse problems formulation, standard compression algorithms, combined detection and estimation, neural networks and expert systems. These techniques are briefly presented through a number of Electricite de France applications or through recent literature results. (author). 1 fig., 20 refs.

  19. Numerical modelling and data assimilation for near-field and continental scale dispersion of radionuclides; Modelisation numerique et assimilation de donnees de la dispersion de radionucleides en champ proche et a l'echelle continentale

    Atmospheric dispersion models are used to forecast consequences of accidental re-leases of radioactivity. Models are based on either analytical, as in the case of PX 0.1, or numerical, as for example in POLAIR3D, solutions to the advection-diffusion equation. Main drawbacks affecting the quality of a forecast are a limited resolution of input meteorological fields and an incomplete knowledge of depletion processes. An investigation of how those drawbacks could be overcome thanks to coupling the models to measurements in data assimilation procedure is presented in this thesis. Model-to-data comparisons have been performed in the first place. The measurements employed in a validation procedure come either from passive tracer experiments or from accidental releases of radionuclides. A wind tunnel experiment for a near-field dispersion on a scale model of Bugey nuclear power station and continental scale ETEX-I experiment as well as the accidental releases in Chernobyl and Algeciras have been studied here. Secondly, measurements have been coupled to the models in order to improve an evaluation of consequences of accidental releases and to invert their sources, should model performance turn out to be sufficiently good. The standard variational method has been used for a near-field dispersion problem. An adjoint of PX 0.1 has been constructed with the help of an automatic differentiator, and the wind tunnel measurements have been assimilated. Capacity of finding the true source emission rate has been tackled in the first place. Next, data assimilation has been employed to accommodate the modelled and measured concentration fields. The required result has been achieved by optimising the parameters which drive the spatial distribution of a plume. Benefit from data assimilation is subject to the quantity of information contained in the measurements. Therefore, posterior analysis of the monitoring network has been carried out and the possibilities of size reduction in view of operational applications have been addressed. At continental scale, despite working exclusively with the grid boxes containing nuclear installations, the space spanned by sources is of significantly greater dimension than the one spanned by observations. Hence, the reconstruction of source position and its emission profile is an ill-posed problem. Its regularisation has been tackled with the maximum entropy on the mean principle. New cost functions, which embody spatial and temporal confinement of an accidental source, have been built. A source-measurement link has been provided by the adjoint of POLAIR3D. The method has been tested with both perfect and noisy synthetic measurements. A series of sensitivity studies have been conducted and the quality of reconstruction assessed with an objective indicator. An algorithm meant for operational usage which allows to reduce the number of suspected sites has also been tested. Finally, the results of inversion of the temporal profile of the Algeciras accidental source have been shown. (author)

    EDF has decided to replace traditional materials by glass reinforced plastic for the manufacture of certain PWR water piping. However, these are liable to in-service degradation through the hydrolysis of the operating conditions which can involve mechanical stresses or specific temperature and humidity conditions. These resins have been the subject of bibliographical surveys and laboratory experiments providing the following main results: the water diffusion in the selected thermoset resins (polyester, vinyl-ester, epoxy) can reach one percent in weight, according to the relative humidity and temperature; the water absorption is a reversible phenomenon, at the beginning and is followed by hydrolysis, an irreversible deterioration affecting the chemical functions of the polymeric chain. Thermally activated, the reaction limits the temperature for the use of these resins; polyester resins are made of a large number of ester bonds and are highly sensitive to hydrolysis. These resins can be classified on the basis of the alcohol and acid which they come acid. A possible hydrolytic degradation does not prevent from using these resins in humid environments. The cooling towers in Belleville, Nogent ad Chooz are equipped with water collecting channels made of polyester laminates which have behaved satisfactorily since their installation in 1982. In acid environments, even concentrated, resins have a better behavior than in a neutral medium. However, they can be liable to stress corrosion. Polyester resins ar not suitable for use in concentrated base media. Vinyl-ester resins are more appropriate for this purpose, although their resistance will be lower than in a neutral environment. When resins are used as a matrix for composites, the presence of glass fibers modifies their behavior. The physico-chemical protection of the fiber/matrix interfaces and of the surface of the glass itself through the sizing of the fibers plays key role in the durability of the composites, which justifies the ongoing studies on hydrolysis at the fiber/matrix interface.

  3. Formulation d'un modele mathematique par des techniques d'estimation de parametres a partir de donnees de vol pour l'helicoptere Bell 427 et l'avion F/A-18 servant a la recherches en aeroservoelasticite

    Nadeau-Beaulieu, Michel

    In this thesis, three mathematical models are built from flight test data for different aircraft design applications: a ground dynamics model for the Bell 427 helicopter, a prediction model for the rotor and engine parameters for the same helicopter type and a simulation model for the aeroelastic deflections of the F/A-18. In the ground dynamics application, the model structure is derived from physics where the normal force between the helicopter and the ground is modelled as a vertical spring and the frictional force is modelled with static and dynamic friction coefficients. The ground dynamics model coefficients are optimized to ensure that the model matches the landing data within the FAA (Federal Aviation Administration) tolerance bands for a level D flight simulator. In the rotor and engine application, rotors torques (main and tail), the engine torque and main rotor speed are estimated using a state-space model. The model inputs are nonlinear terms derived from the pilot control inputs and the helicopter states. The model parameters are identified using the subspace method and are further optimised with the Levenberg-Marquardt minimisation algorithm. The model built with the subspace method provides an excellent estimate of the outputs within the FAA tolerance bands. The F/A-18 aeroelastic state-space model is built from flight test. The research concerning this model is divided in two parts. Firstly, the deflection of a given structural surface on the aircraft following a differential ailerons control input is represented by a Multiple Inputs Single Outputs linear model whose inputs are the ailerons positions and the structural surfaces deflections. Secondly, a single state-space model is used to represent the deflection of the aircraft wings and trailing edge flaps following any control input. In this case the model is made non-linear by multiplying model inputs into higher order terms and using these terms as the inputs of the state-space equations. In both cases, the identification method is the subspace method. Most fit coefficients between the estimated and the measured signals are above 73% and most correlation coefficient are higher than 90%.

    Diffusion coefficients for Si, Ti, Al, Na, K, Ca, Mg and Fe between pairs of glasses of basaltic, rhyolitic or phonolitic compositions have been determinated experimentally. This method involves the heating of coaxial cylinders of paired glasses under atmospheric conditions, over a range of temperatures from 900 to 1300°C, followed by microprobe analysis determination of the concentration gradients across the interface. The measured diffusivities are similar for all cations and range from 10 -13 cm 2/s at 900°C to 5 × 10 -9 cm 2/s at 1300°C. Depending mainly on the composition contrast, the diffusion is characterized by asymmetrical concentration profiles. This peculiar feature increases with temperature and chemical gradients across the contact surface of the glasses and leads to higher diffusion coefficients ( D) in the more "basic" glass of a given pair. In the case of the rhyolite-basalt couple, this variation increases by a factor of about 10 at 1300°C. Diffusion dependence on temperature follows an Arrhenius equation which gives activation energies ranging from 65 to 85 kcal/mole. Assuming a constant and overall D for the two glasses we have attempted to apply our results to some geological examples such as exchanges between molten enclaves and liquids of contrasting composition.

    Migration of gases in argillaceous formations increasingly attracts the attention of various geo-scientific disciplines for purposes like CO{sub 2} sequestration, gas storage in geological formations and disposal of hazardous wastes. Quantitative assessment of gas transport in such ultra-low permeability formations requires information on gas transport properties of the argillaceous formation. A series of hydro- and gas tests in boreholes was performed at the Mont Terri Rock Laboratory in Switzerland to investigate gas transport in the Opalinus Clay, an indurated clay formation of Jurassic age. This paper presents the results of a comprehensive test campaign in the shaly facies of the Opalinus Clay, comprising a 'classical' hydro-test with water injections followed by pressure recovery sequences and an extended gas threshold pressure test. A detailed interpretation of both the hydraulic and gas test sequences was conducted using numerical simulations for the data analysis (software TOUGH2/iTOUGH2). In contrast to former test analyses, the sequential interpretation of the hydro- and gas test sequences provided a consistent set of single-phase hydraulic parameters and two-phase flow parameters. The use of independent information from laboratory testing (porosity, capillary pressure curves) constrained distinctly the inverse problem of parameter fitting. Discrimination between different parametric models of the relative permeability was impaired by inherent limitations of the field data due to non-ideal test conditions. Nevertheless, a classical two-phase flow type capillary pressure - relative permeability relationship based on the Van Genuchten - Mualem approach was found to be valid. A supplementary design study was conducted to optimise the test procedures to better distinguish between relative permeability models. It is shown that long term (> 1 year) injection tests are more adequate to constrain the models. This finding is important for the design of future gas threshold pressure tests in indurated clays.

    This document proposes a critical analysis of the models that describe the actinides and lanthanides complexation by natural organic matter in general and by humic substances in particular. In order to better delimit the particular properties of these substances the most influent physical and chemical properties on complexation are recalled as a preamble. Models as well as data that has been used are reviewed, compiled, and eventually compared to independent data in order to identify (i) their application domain, (ii) the possible simplifications which permit to obtain operational models, (iii) the conditions in which simplifications cannot be ascertained yet, and (iv) the data or fields of knowledge which are still too uncertain. A comparison between the different models is proposed in order to adapt parameters from one model to another minimising the experimental acquisitions, or at least to focus on missing data. Usually, data on the complexation of free ions M{sup z+} are reliable; as soon as hydrolysis, or competition with another ligand in general, in at stake data are much less reliable. Predictions from models are much more uncertain: formation of mixed complexes with hydroxide or carbonate anions is not univocal whatever the modelling strategy. Hints for transfer functions between models which are believed to be incompatible could be explored in order to justify necessary simplifications for using operational modelling. Influence on the solubility of oxides could be quantified, but it is difficult to clearly separate it from colloidal particles stabilisation. The account of the competition between cations by the models has also been tested. In view of the small number of available experimental data there still lie some uncertainties especially for the media that are close to neutrality and in the case of competition with magnesium, but overall in the case of the competition with aluminium and iron. The influence of redox activity of humic substances is also approached in the case of iron and actinides. Although the formal redox couple(s) cannot be yet identified, it seems that an operational E{sub h} = f(pH) relationship can be proposed. (author)

    Three-phase bone scanning of the extremities (foot or hand) was performed in 40 normal subjects and in 56 patients with an unequivocal clinical diagnosis of reflex sympathetic dystrophy. The scintigraphic parameters studied were the ratios of tracer (SUPD SUPG Tc) activity in the affected side over the healthy side established for blood flow, blood pool, early vasculo-tissular fixation, and late bone fixation. In the controls, blood flow, blood pool, and early fixation showed considerable interindividual variation and only the variation of late fixation remained within narrow limits. Statistical analysis revealed that late fixation was most closely correlated with early fixation, which in turn was most close correlated with blood pool. The clinical and pathophysiological significance of these data is discussed. (authors). 33 refs., 2 figs., 5 tabs.

    The present review represents an up-to-date focus on the particular topic of cervix carcinoma. An exhaustive description of the actual data and the near-future combination of radiotherapy and drugs with the specific potential of targeted therapies are presented. This approach represents one of the next challenges to improve results. Studies conducted in 1999, 2000, and 2002 reported the results of six large-scale prospective randomized trials using concomitant chemo radiation with a significant progression-free and overall survival rate improvement compared to radiotherapy only. These results were confirmed by the two last meta-analyses. Nowadays, the concurrent radio chemotherapy schedule used in the treatment of high risk cervical cancer is a standard practice. More growing evidences suggest that intracellular signal pathways play a significant role in radiation response. Several prognostic factors on tumoral radiosensitivity have been identified, including intracellular signal pathways, in the particular case of cervix carcinoma. Promising results have been obtained in experimental studies assessing the combined use of specific inhibitors and radiotherapy. Based on these data, a number of clinical trials have been started to enhance tumor responses and thus, to decrease the rate of recurrences. (authors)

    Stratification of risk (sudden death and infarction) remains a major problem of the way the coronaries are cared. Since 1987, a score based on the test-to-effort data was proposed by Mark and coll. of `Duke University` team. They tried to demonstrate that this score provides a reliable classification of patients. We have compared the results obtained by using this score with those issued from the simultaneous analysis of the left ventricle (LV) function and LV perfusion. A hundred patients afflicted with coronaries (stenoses > 50%) benefited by a coupled study of the LV function and perfusion at rest and under effort made by means of MIBI scintigraphy. The effort test allowed calculating the `Duke` score by means of a formula in terms of the angor index defined as follows: 0 for absence, 1 for angor and 2 for angor motivating cessation. According to Duke score three classes can be defined: patients of low risk, score {>=} 5; patients of intermediate risk, score in between 5 and -10; patients of high risk, score {<=} -10. Ejection fraction at effort acme was measured in every patient as well as the extension of perfusion defect, evaluated semi-quantitatively at effort and rest on the basis of bull`s eye. Three groups of patients were created according to the results of perfusion+function couple: (A)- normal perfusion and function, the case of good prognostication; (B)- patients slightly afflicted (FEV{sub effort} > 50% and in-effort defect extension < 20%) and (C)- patients severely afflicted (FEV{sub effort} <30% or extension >50%). The last criteria were proved by several studies as bad prognostication. A table presents the risks according the Duke score for the three classes. One can observe that one third of the patients severely afflicted by confirmed ischemia are classified in the low-risk class. Besides, the majority of patients are ranked with intermediary risk, independently of scintigraphic results. In conclusion, these results concerning the stratification of coronaries show the superiority of the criteria based on scintigraphy over the score extracted from the effort test

    The objective of this report on the Loire watershed was to broaden at all the nuclear installations of the watershed the method of synthesis made for Saint-Laurent-des-Eaux nuclear power plant, by resting on the whole of actors doing the radioactivity measurements in environment. This report shows that these actors are numerous. The measurement plans implemented have for objective to establish the radiological situation of environment, near or not the nuclear facilities, to detect the abnormal increase of radioactivity, to evaluate the exposure of populations to the ambient radioactivity, or to check the conformity of practices (nuclear activities) and products. This assessment enlightens the lack of a real global strategy in the organisation of the radioactivity measurement at the level of the watershed. The inventory of available data for the Loire watershed allowed to show the diversity of measurements realised. The I.R.S.N. is face to a complex situation of data return in the frame of the implementation of an information system of the national network of radioactivity measurement in environment. (N.C.)

    Qualitative interpretation of data of different nature and sources, based on segmentation techniques such as discriminant analysis, is useful to characterize and monitor hydrocarbon reservoirs. In order to make this interpretation more reliable, it is necessary to characterize uncertainties attached to data and then, to propagate them in the interpretation work-flow. In this thesis, uncertainties are represented by intervals, because usually, little is known about input data errors. The uncertainty characterization issue is dealt with specifically for each case study. The uncertainty propagation issue is treated by a new technique, based on interval analysis, which consists in extending to intervals various popular approaches (non parametric, quadratic and linear) to discriminant analysis: Firstly, a learning phase allows calibrating an imprecise classifying model on the basis of pre-interpreted data. If the quality of this model is good enough, it is used to interpret the whole set of imprecise recorded data. The resulting interpreted model is thus imprecise, but it is also more reliable. A validation study on a synthetic data set is firstly achieved, which compares the developed algorithms with more traditional -simulation based- uncertainty propagation techniques. Finally, two real case studies are presented. The first one consists in a rock-type interpretation of borehole data recorded on the Alwyn field (North Sea). The second one is concerned with monitoring with 4-D seismic the physical changes occurring in the East-Senlac heavy oil pool (Canada) due to steam injection during hydrocarbon production. (author)

    Objectives: the high mammary density, defined by the mammography examination, tends to be regarded currently as a factor of significant and independent risk of breast cancer. We made a statistical methodological analysis of variables studied in the test D.M.I.S.T. of A.C.R.I.N. ( comparison of conventional mammography versus numerical one for 42 000 women, in order to check this hypothesis. Conclusion: the notion of mammary density as risk factor of breast cancer is controverted by this statistical analysis. These findings are susceptible to challenge the evolution of the management recommended for women with dense breasts. The evaluation of mammary density as independent risk factor requires complementary studies on large populations with as imperative statistical base the analysis of a variable clearly isolated (mammary density), and populations equal for the two values of the variable in order to have a significant variance analysis.

O estudo foi motivado pela importância da mensuração do valor justo para as instituições financeiras e pela preocupação de acompanhar evidenciações contábeis que permitam um maior entendimento dos critérios contábeis utilizados. Como contribuição, o trabalho verificou se bancos brasileiros estão se adequando às exigências internacionais, quando a evidenciação da mensuração ao valor justo. A metodologia utilizada foi a regressão em painel e a análise discriminante de dois grupos. Como resultado, o trabalho encontrou uma relação inversa entre o patrimônio líquido (e o retorno sobre o patrimônio líquido e a evidenciação do valor justo. Assim, as evidências do trabalho sugerem que, quanto menor o patrimônio líquido de um banco, maiores são as possibilidades de justificar os resultados pela mensuração ao valor justo, provavelmente, motivados pelos custos políticos.   Palavras-chave Valor justo.

    Detailed experimental studies of cryogenic propellant combustion are needed to improve design and optimization of high performance liquid rocket engines. A research test facility called Mascotte has been built up by ONERA to study elementary processes that are involved in the combustion of liquid oxygen and gaseous hydrogen. Mascotte is aimed at feeding a single element combustor with actual propellants, and the third version in operation since mid 1998 allows to reach supercritical pressures in the combustor. A specific high pressure combustor was developed for this purpose. Research teams from different laboratories belonging to CNRS and ONERA, regrouped in a common research program managed by CNES and SNECMA division SEP, may run experiments on Mascotte, with several objectives: - improve the knowledge and the modeling of physical phenomena; - provide experimental results for computer code validation; - improve and assess diagnostic techniques (especially optical diagnostics). Following diagnostics for instance, were used on Mascotte from 1994 to 1999: - OH imaging (spontaneous emission and laser induced fluorescence ); - CARS temperature measurements (using the H{sub 2} and simultaneously the H{sub 2}O molecules); - High speed cinematography (with a copper vapor laser synchronized to a high speed camera); - O{sub 2} vapor imaging (laser induced fluorescence); - Particle sizing (by means of a Phase Doppler Particle Analyzer).

    The laser anemometry technique is commonly used by the Core Hydraulics Laboratory of the CEA for the determination of the field of flow rates inside fuel rod bundles. The adjustment of measurement point coordinates represents an important part of the velocimetry campaign. In order to increase the number of measurements and the preciseness of the positioning operation, the automation of these preliminary tasks was decided. This work describes first the principle of Doppler laser velocimetry, the components of the measurement system and their functioning conditions. Then, the existing software for tuning and measurement is presented. A new software, called PAMELA, for the automatic positioning of the laser anemometer using a moving table with 5 degrees of freedom, has been developed and tested. This software, written with the LabView language, advises the operator, drives the bench and executes the tunings with a greater precision than manually. (J.S.) 16 refs.

Dentro de um mercado cada vez mais concorrido, o atendimento tende a ser um dos principais diferenciais para as empresas. O objetivo deste estudo foi investigar o tipo de relação existente entre a satisfação dos clientes pessoa física de um Banco com os canais de atendimento e a lucratividade desses. O estudo foi desenvolvido por meio de estudo de caso na agência do Banrisul de Dois Irmãos (RS. Foi estudada uma amostra da população dos 1000 clientes mais rentáveis da agência, visando identificar seus níveis de satisfação com o atendimento pelos canais atendimento pessoal, caixas eletrônicos e internet banking. Após a comparação dos níveis de satisfação com os da lucratividade conhecida de cada respondente, foi possível conhecer quais os atributos e canais mais determinam a satisfação do cliente e sua lucratividade. As principais ferramentas estatísticas utilizadas foram a determinação dos Coeficientes de Correlação de Spearman e a Análise de Regressão. A pesquisa destacou que as dimensões empatia e responsividade do atendimento pessoal foram as mais determinantes para a satisfação dos clientes. Ficou evidenciado também que há uma correlação positiva entre a satisfação e a lucratividade dos clientes e, ainda, que o aumento no nível de satisfação corresponde a um aumento mais que proporcional no nível de lucratividade.The subject of this paper is banking services and its importance for customer's satisfaction and profitability in the service sector. In an increasingly competitive market, costumer service tends to be one of the main differentials for organizations. The objective of this study was to investigate the relationship between individual customers of a bank and its service channels, and profitability. The study was developed through a case study at Banrisul, in the city of Dois Irmãos, RS. A population sample of the 1000 most profitable bank customers was studied focusing in identifying their levels of satisfaction with personal assistance, ATM's and internet banking. After comparing the satisfaction levels with the known profitability levels of each customer it became possible to identify which attributes and services determine more the customer's satisfaction and profitability. The main statistic tools used were the Spearman correlation coefficient and Regression Analysis. The research identified that the dimensions empathy and personal assistance response were the main determinants for customer's satisfaction. It was also evidenced that there is a positive correlation between customer satisfaction and profitability, and also that an increase in the customer's satisfaction level corresponds to a more than proportional increase in the profit level.

    Full Text Available The survey was conducted in a State Bank located in a southeastern state that adopted technologies that led to changes in positions and functions, which required employees to achieve goals and objectives derived from market pressures. The implemented changes began to produce cases of depression and stress amongst workers, who had to be removed from their activities. The survey's goal was to study how the everyday life of the bank's employees had changed following medical leave due to mental and behavioral disorders, evaluating both personal and professional aspects. The theoretical discussion begins with the transformation of the labor market and goes on to analyze mental and behavioral disorders resulting from the new organizational context. References are made to authors who dealt with both of the disorders that are most referred to in the study, i.e., stress and depression, in addition to the Theory of Cognitive Evaluation the Theory of Organizational Justice. We used a qualitative approach, through the technique of content analysis for the treatment of the data that were collected through the self-reporting of employees affected by the disorders. The results show the continued presence of stressors in the workplace, the difficulties of interpersonal relationships and lack of a reintegration program for workers in the workplace.

    Full Text Available este artigo tem por objetivo apresentar uma análise das repercussões das mudanças no psiquismo em trabalhadores que desempenham a função de caixas de um grande banco estatal brasileiro em processo de reestruturação produtiva, com uma atenção particular às formas de mobilização da inteligência, da personalidade no trabalho e na utilização de estratégias coletivas de defesa para enfrentar o sofrimento. Foi utilizada para a pesquisa e a análise dos dados, a metodologia da Psicodinâmica do Trabalho, disciplina que estuda em que situações as condições organizacionais determinam o sentido e a mobilização subjetiva no trabalho, e também as repercussões dessas condições sobre a saúde dos trabalhadores. Foi constatado que a mobilização psíquica provocada pelas mudanças é intensa, a partir de sentimentos de insegurança, estranhamento, desorientação e impotência diante das incertezas das propostas da empresa, sendo a perda do contato com o cliente uma das maiores fontes de sofrimento para o grupo. Há um sentimento de desvalorização, manifestado nas queixas sobre o achatamento salarial, na perda do status que a função proporcionava e na desestruturação de um saber acumulado ao longo dos anos de exercício da função. O sofrimento psíquico dos caixas, provocados pelas reestruturações no trabalho, atingem níveis preocupantes, pois as novas formas de organização do trabalho estão destruindo a imagem do caixa como um profissional e reduzindo a possibilidade de serem reconhecidos pelo exercício da atividade.The objective of this article is to study the consequences in the work in Brazilian banks after the deep changes, mainly after the implementation of the economical plan from 1994 - "Plano Real". In their efforts to adapt themselves to the new economical contingency of the country and to the increase in competition in this sector, the banks have restructured their organisations, downsized their staff, replaced workforce for computerizing systems which allow the treatment of data using less workers. These changes have not occured without consequences for the workers. These people have had to adapt themselves to the new situation, to the increase of pressure of work, of the exposure to risks and, to the end of job stability. Based on a research carried out with cashiers from a bank, an analysis of the repercussion of those changes for the workers' psyche was done with particular attention to the ways of the mobilization of intelligence and of their personality in the work and in the use of collective strategies of defence to fight the suffering. In order to carry out the research and to analyse the data, we have used the theoretical and methodological approaches of the Psychodynamics of Work, a subject which studies in which situations the conditions of the organisations determine the direction and the subjective mobilization in the work as well as the consequences of those conditions on the workers' health.

    Ce projet de recherche porte sur une methode numerique permettant de predire l'evolution du profil 2D de la couche solide qui recouvre l'interieur des parois de plusieurs fours de transformation a haute temperature. Un modele mathematique base sur la formulation faible de l'energie est d'abord developpe et valide. Une methode de transfert thermique inverse reposant sur ce modele est ensuite developpee afin d'obtenir une mesure rapide et continue de l'evolution du profil de cette couche solide. Vu la grande inertie thermique du systeme a l'etude, differentes strategies sont proposees afin de faciliter la mise en uvre de cette methode numerique. Finalement, cette approche inverse est confrontee aux resultats experimentaux obtenus a l'aide d'un reacteur metallurgique. Une etude preliminaire montre que les fours de transformation presentent une tres grande inertie thermique qui limite grandement l'utilisation des methodes inverses. En effet, la sensibilite de cette methode numerique repose essentiellement sur le delai temporel observe entre la variation du profil du banc et la fluctuation de la temperature a la surface externe de la paroi du four. Les resultats obtenus demontrent qu'une partie de ce delai est proportionnel a la chaleur latente de fusion lorsque le materiau a changement de phase est constitue d'un melange non eutectique. Afin de limiter l'impact de ce delai temporel, deux astuces numeriques sont proposees : reutiliser plus d'une fois les mesures de temperature et modifier le probleme thermique dans les regions pateuse et liquide. D'une part, le concept de chevauchement propose permet de reduire le temps d'acquisition des donnees entre chacune des predictions. D'autre part, l'approche virtuelle developpee permet de reduire l'inertie thermique du systeme et, par le fait meme, le delai temporel associe a la diffusion de la chaleur. Ces deux strategies ont permis de predire efficacement l'evolution 1D de l'epaisseur de la couche de gelee qui se solidifie a

    This thesis deals with aspects of seismic behaviour of reinforced concrete shear walls (RCSW). Its objective is to introduce a useful modelling approach for addressing the non-linear response of a large variety of RCSW and to identify several aspects in which this numerical approach could be implemented into design applications. Firstly, the characteristics of the behaviour of RCSW under seismic loading, some design principles and different modelling approaches are discussed. As an important lack of knowledge in several fields was identified, it was considered that three types of shear walls deserve more attention: slightly reinforced slender walls; U-shaped walls and heavily reinforced squat shear walls. A local modelling approach is adopted and the material constitutive models are described in details. Secondly, the behaviour of the two mock-up, CAMUS I and II, tested on the shaking-table during the CAMUS programme, which are slightly reinforced and designed according to the French code PS92 is simulated using a 2-D finite element model (FEM). For comparison purposes, the case of the CAMUS III mock-up, designed according to EC8, is considered. We are then dealing with the case of U-shaped walls under dynamic and cyclic loading. The results obtained from numerical simulations, based on a 3-D shell FEM, are compared with those obtained from tests carried out in the frame of the ICONS programme. Finally, the numerical model is applied to the case of heavily reinforced squat shear walls (similar to those used in the nuclear power plant buildings) subjected to shear loading. A 2-D FEM is considered in order to simulate the behaviour of three different walls, which were tested pseudo-dynamically during the SAFE programme. The results from both experimental and numerical studies are compared and discussed. The most important factors affecting the behaviour of RCSW are highlighted. Different examples of possible contributions to design are presented. (author)

    Seismic hazard assessment relies on the knowledge of the source characteristics of past earthquakes. Unfortunately, seismic waveform analysis, representing the most powerful tool for the investigation of earthquake source parameters, is only possible for events occurred in the last 100-120 years, i.e., since seismographs with known response function were developed. Nevertheless, during this time significant earthquakes have been recorded by such instruments and today, also thanks to technological progress, these data can be recovered and analysed by means of modern techniques. In this paper, aiming at giving a general sketch of possible analyses and attainable results in historical seismogram studies, I briefly describe the major difficulties in processing the original waveforms and present a review of the results that I obtained from previous seismogram analysis of selected significant historical earthquakes occurred during the first decades of the 20. century, including (A) the December 28, 1908, Messina straits (southern Italy), (B) the June 11, 1909, Lambesc (southern France) - both of which are the strongest ever recorded instrumentally in their respective countries - and (C) the July 13, 1930, Irpinia (southern Italy) events. For these earthquakes, the major achievements are represented by the assessment of the seismic moment (A, B, C), the geometry and kinematics of faulting (B, C), the fault length and an approximate slip distribution (A, C). The source characteristics of the studied events have also been interpreted in the frame of the tectonic environment active in the respective region of interest. In spite of the difficulties inherent to the investigation of old seismic data, these results demonstrate the invaluable and irreplaceable role of historical seismogram analysis in defining the local seismo-genic potential and, ultimately, for assessing the seismic hazard. The retrieved information is crucial in areas where important civil engineering works are planned, as in the case of the single-span bridge to be built across the Messina straits and the ITER nuclear fusion power plant to be built in Cadarache, close to the location of the Lambesc event, and in regions characterized by high seismic risk, such as southern Appennines.

    The IPSN experimental station of Tournemire is localized at a 200 m depth inside an abandoned railway tunnel dug in a Jurassic clayey formation. The a priori knowledge of the existing geologic structures of the clayey formations allows to test the reliability of the 3D high resolution seismic survey technique and its capability to detect these structures and discontinuities. This test study is reported in this technical note. It comprises several steps: a bibliographic synthesis and a state-of-the-art of the 3D seismic survey technique, the construction of a velocity model for the different strata of the site, a simulation of the possible seismic response of these strata with respect to the velocities chosen, the processing of the data and finally their interpretation.

    Seismic data contain further geological information than well, due to their good spatial extent. But the seismic measure is band pass limited and the contrasts in acoustic or elastic properties derived from seismic are not directly linked to the reservoir properties. Thus, it is difficult to give a geological interpretation to seismic data. Basically, relevant seismic attributes are extracted at the reservoir level, and then are calibrated with information available at wells by using pattern recognition and statistical estimation techniques. These methods are successfully used in the post-stack domain. But, for multi-cube seismic information such as pre-stack or 4D data, the number of attributes can considerably increase and statistical methods are not often used. It is necessary to find a parameterization allowing an optimal description the seismic variability in the time window of interest. We propose to extract new attributes from seismic multi-cube data with Generalised Principal Analysis and to use them for reservoir interpretation with statistical techniques. The new attributes can be clearly related to the initial data set, and then be physically interpreted, while optimally summarizing the initial seismic information. By applying the Generalised Principal Analysis to 3D pre-stack surveys, the contribution of the pre-stack seismic information to reservoir characterisation is compared to the post-stack seismic one, in both synthetic and real cases. By applying the Generalised Principal Analysis to real 4D surveys, the seismic repeatability is quantified and the seismic changes in the reservoir with calendar time are highlighted and interpreted. A coherency cube has also been defined, based on the Generalised Principal Analysis. This attribute is a coherence measurement in three dimensions representing the local similarity between 4D or AVO surveys. (author)

    Development of the Soultz-sous-Forets HDR (Hot Dry Rock) geothermal energy project will involve important fluid injections which will induce micro-seismic events. This thesis discusses the natural seismicity of the region and induced seismicity associated with fluid injections. A catalogue of all historical and instrument seismicity of the Soultz-sous-Forets (SSF) region has been compiled. This seismicity does not correspond to movements along the major tectonic features of the region. The area around SSF has been identified as being one where high heat flow corresponds to low seismicity. The largest well documented seismic event in the region which took place in 1952 had an epicentral intensity of VI. All important data pertaining to the series of seismic events which took place in the region from August to October 1952 have been collected and are presented. This work details the installation and operation of a permanent 3 station network of accelerometers and seismometers around the HDR site. Also the installation and operation of a mobile network of vertical seismometers during fluid injections. 167 micro-seismic events were recorded on the surface network, with magnitudes from -0.5 to 1.9. The preferential alignment of the micro-seismic cloud is N160 deg. Individual focal mechanisms of the larger seismic events correspond to an extensional tectonic regime. Stress inversion of P wave polarities indicates that the maximum stress is vertical and the intermediate and minimum stress axes horizontal. The largest of the horizontal stresses is orientated N124 deg and the smallest N34 deg. Induced seismic movement is taking place on pre-existing fractures controlled by the in situ stress seismic movement is taking place on pre-existing tectonic fractures controlled by the in situ stress field, and the largest of the induced events had a magnitude 1.9. This level of seismicity does not pose any environmental hazard to the region around Soultz-sous-Forets. (author) 151 refs.

    Quebec's Office of Public Inquiry on the Environment (Bureau d'audiences publiques sur l'environnement) conducted public hearings on the environmental issues associated with seismic surveys carried out in the Gulf of St. Lawrence and its estuaries for the purpose of petroleum and natural gas exploration. The inquiry focused on the effect of sound waves on aquatic ecosystems and marine organisms and the associated environmental, social and economic consequences of seismic surveys. Environmental groups, scientists, fishermen and the maritime tourist industry have been concerned with the impact of seismic surveys in the Estuary and the Gulf of St. Lawrence since the autumn of 2002, when Hydro-Quebec publicized its 2002-2010 plan for oil and gas exploration and when Geophysical Service Inc. received a mandate from Hydro-Quebec to carry out seismic surveys in the area. This report presents 10 recommendations and 16 opinions resulting from 18 public hearings held in communities along the Gulf of St. Lawrence. Although the thousands of kilometres of seismic survey lines acquired in the Estuary and the Gulf of St. Lawrence since 1960 do not seem to have had any visible impact on the marine environment, the Commission has taken a precautionary approach and recommends that some practices should be limited until a review of literature demonstrates that seismic surveys do not affect the ecological integrity of the St. Lawrence for fisheries or ecotourism. 16 refs., 9 tabs., 5 figs., 2 appendices.

    . Dans la partie theorique, un modele traitant les aspects thermique, hydrodynamique et massique a ete elabore. Sur la base de ce modele a ete ecrit un programme informatique en langage FORTRAN 6.6. Il est base sur la discretisation du serpentin en volumes de controle, est entierement automatise et peut traiter des echangeurs de chaleur avec des circuits de refrigerant complexes pouvant avoir des entrees et sorties multiples ainsi que des bifurcations. La presence simultanee des trois phases thermodynamiques du refrigerant (liquide sous refroidi, fluide sature, vapeur surchauffee) dans le serpentin est aussi prise en charge. Le modele a ete valide pour un fonctionnement avec et sans formation de givre en utilisant des donnees experimentales disponibles dans la litterature et celles obtenues sur le banc d'essai de CanmetENERGIE. Celui-ci a ete mis a jour pour les besoins de la presente recherche et pour cela, un systeme de surchauffe et d'injection de la vapeur d'eau dans une enceinte a tres basse temperature a ete dimensionne, fabrique et installe. Un dispositif de visualisation de la formation de givre, ainsi qu'un equipement de mesure de la temperature, de la pression et de l'humidite relative de l'air ont aussi ete ajoutes. Une fois le modele valide, des simulations numeriques sur le serpentin avec et sans formation de givre ont ete effectuees. Un premier cas de base a servi comme reference pour d'autres cas pour lesquels une etude parametrique sur la geometrie et le fonctionnement a ete menee. Il a ete montre par rapport au cas de base que : 1. la diminution de la densite des ailettes sur des rangees specifiques du serpentin donne une surface minimale (Amin) plus grande, retardant ainsi l'obstruction totale du serpentin par le givre et permet donc un temps de fonctionnement plus grand et une frequence de degivrage plus faible. 2. une bonne configuration de circuit de refrigerant augmente le temps de fonctionnement du serpentin de 200 % et delivre une puissance

    és dans la sismicité historique, il a été proposé une échelle de détermination de paléointensités sismiques d’après l’intensité de la déformation par liquéfaction. La répartition des intensités >VI (MM/MSK définies par cette échelle montre une bonne cohérence avec la distribution des intensités définies par la sismicité historique. L’utilisation de la sismicité historique et de la paléosismicité géologique définit une récurrence moyenne de 115 ans pour les événements majeurs d’intensité >VII. Il faut noter ici que le dernier événement correspondant à cet intervalle d’intensités est survenu en 1868, il y a plus de 125 ans, mais également que, au cours des 460 ans d’histoire, il a été observé des intervalles de récurrence allant de 168 ans à seulement 9 ans. L’utilisation de l’échelle citée ci-dessus a également permis de mettre en évidence la probable ocurrence d’un séisme d’intensité IX-X (MM/MSK entre le Xème et le XVIème siècle. Dans la ville, plusieurs niveaux paléosismiques ont pu être corrélés avec cet événement grâce à la présence d’un banc repère d’origine volcanique déformé par ce séisme. Ces niveaux ont pu également être corrélés dans le bassin avec des déformations sismotectoniques, faisant ainsi de la faille de Quito le candidat le plus probable pour expliquer une telle intensité dépassant le maximum historique de près d’un degré d’intensité. A lo largo de los 460 años de historia escrita que tiene la ciudad de Quito, se han registrado varios eventos sísmicos que alcanzaron intensidades de hasta IX grados en la escala MSK. Dentro de las numerosas fuentes sismogenéticas que pueden generar daños en la ciudad, se identifica la falla de Quito, cuya actividad es susceptible de producir intensidades superiores a VIII grados, haciendo de ella una fuente de alto peligro para la ciudad. En el registro histórico, se atribuye al sismo de 1755 como producido por la actividad de esta

    The command and control system for the Vivitron, a new generation electrostatic particle accelerator, has been implemented using workstations and front-end computers using VME standards, the whole within an environment of UNIX/VxWorks. This architecture is distributed over an Ethernet network. Measurements and commands of the different sensors and actuators are concentrated in the front-end computers. The development of a second version of the software giving better performance and more functionality is described. X11 based communication has been utilised to transmit all the necessary informations to display parameters within the front-end computers on to the graphic screens. All other communications between processes use the Remote Procedure Call method (RPC). The conception of the system is based largely on the object oriented database O{sub 2} which integrates a full description of equipments and the code necessary to manage it. This code is generated by the database. This innovation permits easy maintenance of the system and bypasses the need of a specialist when adding new equipments. The new version of the command and control system has been progressively installed since August 1995. (author) 38 refs.

    The dusts production during exploitation in cells is the main source of bio-aerosols emission in storage centers. This report presents data on biological characterization of domestic wastes and the related atmospheric emissions. It concludes that the sanitary risk for the residents is weak and the 200 m area decided by the regulation is sufficient. Meanwhile it is recommended to control the emission levels during particularly meteorological conditions as humid, windy and not very sunny. (A.L.B.)

    This thesis is dedicated to the study of the first data taken by the D0 detector during the Run II of the Tevatron. Supersymmetric particles have been search for in proton-antiproton collisions, with a center of mass energy of 1.96 TeV. In the framework of supersymmetry with R-parity violation, I have studied the pair production of Gauginos, leading to a pair of LSP (0,{chi}{sub 1}), each one decaying into ee{nu}{sub {mu}} or e{mu}{nu}{sub e} with a {lambda}(121) coupling. The final state contains at least two electrons: I have thus paid special attention in this work to the methods concerning identification and mis-identification of electromagnetic particles, as well as reconstruction, triggering, and correction (of the reconstructed energy). In a selection of tri-leptons, with at least two electrons, and some transverse missing energy, we observed 0 event in the 350 pb{sup -1} of analyzed data, for 0.4 + 0.35 - 0.05 (sta) {+-} 0.16 (sys) expected from the Standard Model contributions. In the signal considered in this analysis, the selection efficiency is around 12 per cent. Results have been studied in two models: mSUGRA and MSSM. In mSUGRA model, limits on m(1/2) and lightest gauginos's masses have been obtained, with tan({beta}) = 5, A{sub 0} = 0, m{sub 0} = 100 and 1000 GeV.c{sup -2} and both signs of {mu}. In MSSM, with the hypothesis of massive sfermions (1000 GeV.c{sup -2}), we can exclude, at 95% Confidence Level, the region m({chi}{sub 1}{sup {+-}}) < 200 GeV.c{sup -2} for all masses of {chi}{sub 1}{sup 0} LSP.

    Granite and gneiss have been sampled on the submarine fault scarps of the Sardinia Channel and have been dated using the {sup 40}Ar/{sup 39}Ar method. The majority of rocks partially preserve Hercynian ages. Some of them display Lower Cretaceous ages. In addition, Upper Eocene-Oligocene argon resetting is recorded only in rocks from the southeast sector of the Channel. We thus propose that the basement of the Sardinia Channel occupied a shallow position within the stack of the Alpine tectonic units, behind the more deformed front of the internal zones of the Maghrebide Chain.

    Neutron transport simulation of nuclear reactors is based on the knowledge of the neutron-nucleus interaction (cross-sections, fission neutron yields and spectra...) for the dozens of nuclei present in the core over a very large energy range (fractions of eV to several MeV). To obtain the goal of the sustainable development of nuclear power, future reactors must have new and more strict constraints to their design: optimization of ore materials will necessitate breeding (generation of fissile material from fertile material), and waste management will require transmutation. Innovative reactors that could achieve such objectives - generation IV or ADS (accelerator driven system) - are loaded with new fuels (thorium, heavy actinides) and function with neutron spectra for which nuclear data do not benefit from 50 years of industrial experience, and thus present particular challenges. After validation on an experimental reactor using an international benchmark, we take classical reactor physics tools along with available nuclear data uncertainties to calculate the sensitivities and uncertainties of the criticality and temperature coefficient of a thorium molten salt reactor. In addition, a study based on the important reaction rates for the calculation of cycle's equilibrium allows us to estimate the efficiency of different reprocessing strategies and the contribution of these reaction rates on the uncertainty of the breeding and then on the uncertainty of the size of the reprocessing plant. Finally, we use this work to propose an improvement of the high priority experimental request list. (author)

    The method of direct detection of WIMPs (weakly interactive massive particles) that are present in the halo of our galaxy rests on the detection of their interaction with a target nucleus. The Edelweiss experiment uses this technique with 3 cryogenic detectors operating on 2 modes ionization and heat. Each detector is made of a 320 g germanium crystal with 2 faces equipped with electrodes. In order to improve the collection of charges, an amorphous layer of Ge or Si is laid between the crystal surface and the electrodes. The validation of the detector system has been made with Co{sup 57} and Cs{sup 137} gamma sources and a Cf{sup 252} neutron source. We present a comparison with simulation results and experimental data for the validation of the response to nuclear recoils. The whole experimental data collected by Edelweiss-I from 2000 till 2003 has been analysed. 40 events have been selected, 6 among them with an energy over 30 keV. Limits for the interaction cross-section between a WIMP and a nucleon have been deduced from the experimental data. The Yellin method has enabled us to determine a limit without knowing the background noise. The best sensitivity appears to be 1.5*10{sup -6} pb for a WIMP's mass of 80 GeV/c{sup 2} and a confidence level of 90 per cent. In terms of events, the limit for an energy range of 30 - 100 keV is 0.12 events per kg and per day. (A.C.)

For the second study, whatever the studied scenario, the R.I.V.M. (Riijksinstituut Voor Volksgezondheid en mileuhygiene) Dutch organism report concludes to a risk qualified as acceptable for the voluntary workers and professionals, included the birds cleaners. The risk of skin cancer consecutive to the skin exposure has been characterized with a dose response relationship model coming from previous works of the R.I.V.M. (N.C.)

    The work presented in this thesis has contributed to the development of the Compact Muon Solenoid detector (CMS) that will be installed at the future Large Hadron Collider (LHC) which will start running in summer 2007. This report is organised in three parts: the study of gaseous detectors and silicon micro-strips detectors, and a development of a software for the reconstruction and analysis of CMS data in the framework of ORCA. First, the micro-strips gaseous detectors (MSGC) study was on the ultimate critical irradiation test before their substitution in the CMS tracker. This test showed a really small number of lost anodes and a stable signal to noise ratio. This test proved that the described MSGC fulfill all the requirements to be integrated in the CMS tracker. The following contribution described a study of silicon micro-strips detectors and its electronics exposed to a 40 MHz bunched LHC like beam. These tests indicated a good behaviour of the data acquisition and control system. The signal to noise ratio, the bunch crossing identification and the cluster finding efficiency had also be analysed. The last study concern the design and the development of an ORCA algorithm dedicates to secondary vertex reconstruction. This iterative algorithm aims to be use for b tagging. This part analyse also primary vertex reconstruction in events without and with pile up. (author)

    Purpose. - In cervix carcinoma: (a) to evaluate the ability of ({sup 18}F)-fluorodeoxyglucose (FDG) positron emission tomography (PET) in the lymph node detection; (b) to investigate the prognostic and predictive value of the primary cervical PET parameters. Patients and methods. - Ninety patients treated for cervix carcinoma and evaluated initially by MRI and FDG PET were included. The performances of FDG-PET for lymph node detection (relatively to the lymph node dissection) have been described (sensitivity, specificity, positive predictive value and negative predictive value). PET tumour parameters analyzed were: maximum standard uptake value (SUV{sub max}), the volume and the maximum diameter. The prognostic and predictive values of these parameters were investigated. The tumour response was evaluated on surgical specimens. Results. - PET detected the cervical tumour with a sensitivity of 97% (mean values: SUV{sub max} = 15.8, volume = 27 mm{sup 3}, maximum diameter = 47). For the detection of the lymph nodes, the values of sensibility, specificity, positive predictive value and negative predictive value were: 86, 56, 69 and 78% in the pelvic, and 90, 67, 50 and 95% for the para-aortic area, respectively. The SUV{sub max} was correlated with histologic response (P = 0.04). The frequency of partial histological response was significantly higher for tumour SUV{sub max}> 10.9 (P = 0.017). The maximum PET diameter and pathologic response had an impact on disease-free survival and overall survival in multivariate analysis (P < 0.05). Conclusion. - PET has high sensitivity in detecting pelvic and para-aortic lymph nodes. Some primary cervical tumour PET parameters are useful as prognostic and predictive factors. (authors)

    Objective: To determine the risk of lung cancer associated with exposure at home to the radioactive disintegration products of naturally occurring radon gas. Design: Collaborative analysis of individual data from 13 case-control studies of residential radon and lung cancer. Setting: Nine European countries. Subjects: 7148 cases of lung cancer and 14 208 controls. Main outcome measures: Relative risks of lung cancer and radon gas concentrations in homes inhabited during the previous 5-34 years measured in becquerels (radon disintegrations per second) per cubic metre (Bq/m3) of household air. Results: The mean measured radon concentration in homes of people in the control group was 97 Bq/m3, with 11% measuring > 200 and 4% measuring > 400 Bq/m3. For cases of lung cancer the mean concentration was 104 Bq/m3. The risk of lung cancer increased by 8.4% (95% confidence interval 3.0% to 15.8%) per 100 Bq/m3 increase in measured radon (P=0.0007). This corresponds to an increase of 16% (5% to 31%) per 100 Bq/m3 increase in usual radon- that is, after correction for the dilution caused by random uncertainties in measuring radon concentrations. The dose-response relation seemed to be linear with no threshold and remained significant (P = 0.04) in analyses limited to individuals from homes with measured radon < 200 Bq/m3. The proportionate excess risk did not differ significantly with study, age, sex, or smoking. In the absence of other causes of death, the absolute risks of lung cancer by age 75 years at usual radon concentrations of 0, 100, and 400 Bq/m3 would be about 0.4%, 0.5%, and 0.7%, respectively, for lifelong non-smokers, and about 25 times greater (10%, 12%, and 16%) for cigarette smokers. Conclusions: Collectively, though not separately, these studies show appreciable hazards from residential radon, particularly for smokers and recent ex-smokers, and indicate that it is responsible for about 2% of all deaths from cancer in Europe.

    In this thesis, we study fractures from borehole data on two sites: in one, located at Soultz-sous-Forets (Alsace) in the Rhine graben, boreholes reach a delta Jurassic series forming a petroleum reservoir. At Soultz, fractures have been studied on cores and borehole images. Striated faults present on cores permit to determine the tectonic history of the granite, completed by field study in Vosges Massif. This history corresponds to the Rhine graben history knowing by different authors. The analysis of vertical induced fractures observed on borehole images indicates a present-day NW-SE to NNW-SSE compression. These variations of stress direction are confirmed by others in situ measurements, as hydraulic injection, micro-seismicity, etc... On cores and borehole images, numerous fractures have been observed. Most of them are linked to the E-W distension, which permits the Rhine graben opening at Oligocene. At greatest scale, in quartz minerals, the micro-fractures are constitute by fluid inclusion trails. Several sets are related to the E-W distension, but others sets are linked to compressive stages. These sets are not observed on cores. This is a under-sampling of some fractures by the boreholes, but theses fractures exit into to rock massif. On borehole images, fracture density is weakest than the cores, however the set organisation is the same. At Ravenscar, the distribution of fracture spacing along different unidirectional sampling shows a exponential negative law. However, the fracture density varies with sampling. (author) 199 refs.

    This final report prepared for the Swiss Federal Office of Energy (SFOE) describes the monitoring equipment and the results of performance tests made on a prototype heat pump of 60 kW power output used for hot water production at the hospital of Le Locle, Switzerland. The heat pump uses carbon dioxide (R744) as the working fluid and ambient air as the heat source. The heat output and the coefficient of performance for various values of cold water temperature and air temperature have been measured. The practically measured values of heat output and COP showed a low reproducibility and remained far behind the theoretical values given by the manufacturer. Instead of producing hot water at 80 {sup o}C as intended originally the authors recommend to use the heat pump only for preheating the water to 60 {sup o}C.

    This research project focused on predicting the composition of several coal seams currently being worked in different coal faces, within two neighbouring collieries of the Campine coal field (N.V. Kempense Steenkolenmijnen). This prediction is based on the interpretation of computer-processed geological data collected from the colliery archives or obtained during mining operations. Existing software packages were adapted to process the geological data. The different computer-generated graphic documents have been evaluated for their use as predictive tools in coal mining. It is noted that the reliability of subsurface geological observations is an absolute requirement for optimal underground coal mining operations. 27 refs., 54 figs.

    Wabamun, au centre de l’Alberta (Canada. Des études antérieures ont montré le potentiel offert par les aquifères salins profonds de la région pour le stockage géologique de ce gaz et le présent article rend compte d’une caractérisation des carbonates dévoniens de la formation Nisku, en vue de réaliser un stockage de CO2. Une telle caractérisation doit surmonter plusieurs handicaps : données de puits et de sismique réflexion assez rares et dispersées, tests en forage de qualité médiocre et rareté des mesures modernes. Des diagraphies de porosité ne sont disponibles que pour un tiers des puits, de sorte qu’on a utilisé les diagraphies de résistivité pour évaluer la porosité et la transmissivité (perméabilité  ×  épaisseur. Le facteur de cimentation d’Archie vaut entre 2 et 3, ce qui maintient une incertitude quant à l’estimation de la porosité ainsi obtenue; toutefois, on peut identifier les intervalles de forte porosité. En ce qui concerne la transmissivité, les valeurs déduites des logs sont mieux corrélées à celles provenant des mesures sur carotte qu’à celles obtenues par DST ou test de production. Un tel comportement n’est pas surprenant, car les tests sont moins sensibles à l’occurrence très locale de bancs rendus extrêmement perméables par une porosité vacuolaire (vuggy ou moldic. La distribution des faciès sédimentaires a été modélisée à l’aide de deux approches, de type “pixel” ou de type “objet”. La seconde, qui utilise des dimensions obtenues par imagerie satellitaire sur des environnements actuels, fournit des résultats plus cohérents avec la compréhension géologique que l’on a de la formation de Nisku, et se traduit par une connectivité à large échelle supérieure à celle obtenue par la méthode “pixel”. Les volumes obtenus indiquent une capacité potentielle de stockage considérable dans cette formation, toutefois les simulations hydrauliques laissent penser que l

    Full Text Available A presente pesquisa teve como objetivo investigar as percepções e significados atribuídos ao emprego bancário público por trabalhadores de um banco federal. O primeiro movimento foi analisar, por meio de uma revisão da literatura, o processo de reestruturação produtiva, iniciado na década de 1990. Num segundo momento, via análise de documentos disponíveis no Centro de Documentação do Sindicato dos Bancários de São Paulo, buscamos caracterizar os principais fatos e mudanças ocorridos no banco pesquisado durante a década de 1990. Por fim, vinte entrevistas semi-estruturadas foram realizadas, sendo: dez com Escriturários, ou seja, funcionários contratados na primeira metade da década de 1990, ou em período anterior, e que, por isso, vivenciaram a reestruturação produtiva no setor bancário; e dez com Técnicos Bancários, isto é, funcionários que ingressaram no banco por meio do concurso de 1998 ou de concurso posterior. Constatamos que para a nova geração de bancários a percepção oriunda de uma comparação sincrônica, na qual o emprego aparece como uma alternativa diante de experiências de trabalho temporário, instável ou flexível, parece amoldar a percepção advinda de uma análise diacrônica, que evidencia as perdas históricas do emprego bancário. É dessa maneira, que a estabilidade, sobretudo para os Técnicos Bancários, dissociada da remuneração e do status, se agiganta, tornando-se o elemento central no processo de re-significação do emprego bancário público

    T2K is a neutrino oscillation experiment that will use the intense 2.5 degrees off-axis {nu}{sub {mu}} beam produced at J-PARC (Japan). The far detector is Super-Kamiokande (SK), the 50 kt water Cherenkov detector located 295 km from J-PARC. The goal is to search for {nu}{sub e} appearance, which will bring new information on {theta}{sub 13}. The main background for {nu}{sub e} appearance comes from intrinsic beam {nu}{sub e} events ({approx} 55%), and from mis-identified neutral current {pi}{sup 0} events ({approx} 45%); near detectors are needed to measure these background components before oscillation. A detector complex (2KM) including a water Cherenkov detector, located {approx} 1.8 km away from the source is under active study. This distance is advantageous because the neutrino spectrum is only a few percent different from that of SK, thereby reducing extrapolation systematics. In order to match SK performance, the water Cherenkov detector was designed with {approx} 5600 8-inch photo-multiplier tubes, after studies based on full simulation tuned to K2K data. The water Cherenkov reconstruction algorithms, mainly particle identification and e/{pi}{sup 0} separation, were also studied at 2KM. Studies of {nu}{sub e} appearance in the water Cherenkov detector show that using simple scaling extrapolation we conservatively predict 23.0 {+-} 8.0% (stat + syst) background events at SK for 5. 10{sup 21} p.o.t., in excellent agreement with the 23.8 background events obtained from an independent simulation of SK. The 2KM detector can achieve background subtraction to better than 10% accuracy, sufficient for T2K phase I. Detailed sensitivity studies, including all the relevant sources of systematics, show that the 2KM detector improves the sensitivity to sin{sup 2}(2{theta}{sub 13}) down to {approx} 1.4. 10{sup -2} at 90% CL.

Paralelamente, observa-se uma maior exposição histórica dos Bancos ao risco de inadimplência, ou seja, o do não-recebimento (parcial ou total de créditos rotativos utilizados pelas pessoas físicas. Considerando o tamanho e a importância desse mercado aos grandes Bancos Comerciais e a economia como um todo, direciona-se essa pesquisa para: 1. detalhar os processos de análise subjetiva e objetiva de crédito realizada pelos principais Bancos privados nacionais; 2. abordar a função seletiva das taxas de juros em créditos rotativos; 3. destacar as principais características dos modelos de credit scoring e 4. propor um modelo de credit scoring para créditos rotativos composto por variáveis sistêmicas e não-sistêmicas, direcionado à redução do risco de inadimplência.

Likewise, a more significant historical exposition of the banks to insolvency risk is being observed, such as the risk of not getting paid (partially or totally and the revolving credit borrowed by consumers. Considering the size and the importance of this market to the great commercial banks and to the economy as a whole, the scope of this research comprises the following points: 1. detailing the processes of subjective and objective credit analysis carried out by the main domestic private banks; 2. approaching the selective function of interest rates in revolving credits; 3. highlighting the main characteristics of credit scoring models; and 4. proposing a model of credit scoring for revolving credits. This model is based on systemic and non-systemic variables and directed to the reduction of insolvency risk. The applicability of the credit scoring model proposed in a sample, extracted from the consumers credit portfolio which belongs to an important medium size Brazilian private commercial bank (Bank X - fictitious name, presented a satisfactory accuracy level in the identification of prospective (96% and non-prospective (92% clients, which led to the conclusion that it included and considered adequately the representative variables of borrowers’ payment capability.

Após os programas saneadores implementados pelo governo e a regulamentação de provisionamento, editada pelo CMN através da Resolução n. 2.682, verificou-se uma mudança do patamar de provisionamento da carteira de crédito, que passou dos 2,2% verificados em dezembro de 1995 para os 6,8% registrados em dezembro de 2005.After the implantation of the Plano Real, the Sistema Financeiro Nacional - SFN (National Financial System started going through great and significant changes. The rising of interest rates and the end of the inflationary revenues brought along the risk of bankruptcy for some financial institutions. In this context, the government launched a series of measures in order to reorganize the national financial system, particularly Resolution No. 2.682 of the Conselho Monetario Nacional - CMN (National Monetary Council, aiming at improving regulations on financial institutions' provisioning of credit portfolios. This study intends to answer the following question: what is the impact of resolution No. 2.682 and the Restructuring Programs of the National Financial System on the financial institutions' level of Provisão para Creditos de Liquidação Duvidosa - PCLD (Doubtful Liquidation Credit Provision? A documental and bibliographical research was carried out, as well as a behavioral analysis of the credit portfolio of the National Financial System. The study reveals that, after the reorganization programs implanted by the government and the provisioning regulation edited by the CMN, there was a change in the provisioning status of credit portfolios, which rose from 2.2% in December 1995 to 8.8% registered in December 2005.

    In this 'Drilling-Production' section, in which 7 papers are gathered, 3 main topics are developed: (1)the deep-sea drilling (2)the practical aspects of 4D seismic (3)the 'SIRRI' and 'DOROOD' operating plans in Iran. Concerning the first point, it can be noticed that nowadays, mobile platforms are located in great offshore where water depths are of about 2400 m. In the second point is particularly detailed what 4D is, what it can do, what the primary conditions for it works are and how it costs. The third point is the more particularly detailed in this section (15 pages). At first an introduction indicates why Iran has to call to international petroleum investors, what the current problems of Iran are, what Iran has to do to attract foreign investment and technology and what the challenges to foreign companies are. Then the two operating plans: 'SIRRI' and 'DOROOD' are exposed into details. A synthesis of these plans, called of 'Buy Back', (production, investment, refund) is given as well as their advantages and disadvantages. (O.M.)

    Beaulac, Philippe

    Ce memoire est le resultat d'une recherche qui visait le developpement d'un modele de moteur diesel a I' aide d'un logiciel commercial, GT Power. Ce modele permet de tester certaines hypotheses pour optimiser la recuperation d'energie d'un systeme hybride eolien-diesel avec stockage d'air comprime. L'energie stockee sous forme d'air comprime pourrait etre utilisee afin de reduire la consommation en carburant du moteur diesel. Les resultats anticipes pourraient etre utilises dans des sites isoles du nord canadien, ou l'energie est beaucoup plus dispendieuse a rendre disponible aux consommateurs. La methodologie preconisee consistait a relever des donnees de performances sur un groupe electrogene modifie avec des capteurs, charges resistantes, interface et apport d'air comprime. Les donnees pouvaient etre utilisees afin d'ajuster le modele developpe. Une fois le modele bien ajuste, les hypotheses d'optimisation sont mises a l'essai avant de tenter de modifier le moteur physique en tant que tel. Les resultats obtenus ne sont pas aussi concluants que desires, compte tenu du bris d'un capteur de pression critique et d'echeanciers trop serres pour permettre de reprendre les essais. Par contre, les donnees colligees de la simulation du modele demontrent que le modele et done le logiciel GT Power peuvent bel et bien foumir l'outil de confirmation souhaite pour justifier des travaux de modification de concept de moteur.

    Full Text Available Programs have been developed that use a backpropagation neural network to automatically edit noisy seismic traces and pick first break refraction events. This paper shows that neural network-based trace editing and first break picking can achieve 85 to 98 percent agreement with manual methods for seismic data of moderate to good quality. Productivity improvements over current manual editing and picking techniques for 2D seismic data should range between 60 and 90 percent. For 3D seismic data sets efficiency increases of up to 800 percent have been demonstrated in a production processing environment. Nous avons développé des programmes utilisant les réseaux neuronaux et la rétropropagation pour l'édition automatique de traces bruitées et le pointé des premières arrivées. Cet article montre que les réseaux neuronaux peuvent donner des résultats en accord à 85-98% avec les méthodes manuelles d'édition de traces et de pointé des premières arrivées sur des données sismiques de qualité moyenne ou bonne. Les gains de productivité par rapport aux techniques manuelles actuelles d'édition et de pointé sur des données sismiques 2-D se situeraient de 60 à 90 %. Pour des jeux de données sismiques 3D, des gains de productivité allant jusqu'à 800 % ont été obtenus en production.

    Full Text Available This paper presents the blind test experiment set up for the EAEG workshop on Practical Aspects of Seismic Inversion(Berlin, 1989. The target was to review the possibilities provided by seismic data inversion at the end of the 1980's. This blind test consisted in deriving an acoustic impedance cross-section from a poststack seismic section and an impedance log. The control of the solution was made by comparison of the solution with logs at different well locations, these logs being kept hidden before the workshop. We give a mathematical formulation of the considered seismic inverse problem and we describe in detail the blind test experiment. We present the results obtained during this blind test with two software packages: SPIDER (Elf Aquitaine and INTEGRATE (Jason Geosystems. These results and other results presented during the workshop (see the papers in this issue illustrate the effectiveness of seismic inversion and the importance of integrating geological information during the inversion process. L'inversion de données sismiques est un problème qui a suscité l'intérêt des géophysiciens pendant les dernières décennies (Kunetz, 1963; Bamberger et al, 1977, 1982; Lavergne et Willm, 1977; Gjevik et at, 1976; Lindseth, 1979; Oldenburg et al, 1983; Duijndam et Van Riel, 1980, . . . . L'intérêt de cette approche est de fournir à partir des données sismiques une estimation quantitative des distributions de certains paramètres physiques caractéristiques du sous-sol. De plus certaines de ces méthodes permettent d'intégrer des données non sismiques (données de puits, information géologique pour la construction du résultat. Ces méthodes débouchent donc sur une autre conception de l'interprétation stratigraphique : la section à interpréter est une distribution de paramètre physique (souvent l'impédance acoustique qui est censée intégrer toutes les informations manipulées par l'interprétateur (sismique, diagraphies

    Full Text Available RESUMO As iniciativas de educação corporativa vêm se institucionalizando como elemento de competitividade entre países (LANVIN; EVANS, 2013, organizações (EBOLI et al. 2010 e indivíduos (SARSUR, 2010. Como parte do resultado da melhor estruturação da educação corporativa, a qualificação da mão de obra traz no seu bojo os processos de certificação profissional. Neste contexto, o sistema financeiro brasileiro revela instituições mais efetivas na intermediação financeira e na geração de resultados, lastreadas em ações de educação corporativa e políticas de gestão de pessoas. O presente artigo delineia esta perspectiva analisando o movimento de certificação de trabalhadores bancários no Brasil, sob a égide de atores distintos como o órgão regulador; os bancos e suas universidades corporativas; as certificadoras; os sindicatos e os bancários. Verificaram-se por meio de pesquisa qualitativa de cunho descritivo, utilizando-se como instrumentos de coleta de dados a análise documental, entrevistas e grupo de foco, as políticas de gestão de pessoas sob o escopo da educação corporativa e o processo de certificação bancária sob a perspectiva destes atores. Os principais achados indicam que o Banco Central do Brasil normatiza o mercado, os bancos induzem ao processo de certificação bancária como mecanismo de ampliação de competitividade e pressão sobre o indivíduo enquanto trabalhador, e por sua vez os sindicatos atuam como coadjuvantes no processo.

    The mitochondrial adenine nucleotide carrier (Ancp) catalyzes the transport of ADP and ATP across the mitochondrial inner membrane, thus playing an essential role in cellular energy metabolism. During the transport mechanism the carrier switches between two different conformations that can be blocked by two toxins: carboxyatractyloside (CATR) and bongkrekic acid. Therefore, our understanding of the nucleotide transport mechanism can be improved by analyzing structural differences of the individual inhibited states. We have solved the three-dimensional structure of bovine carrier isoform 1 (bAnc1p) in a complex with CATR, but the structure of the carrier-bongkrekic acid complex, and thus, the detailed mechanism of transport remains unknown. Improvements in sample processing in the hydrogen/deuterium exchange technique coupled to mass spectrometry (HDX-MS) have allowed us to gain novel insights into the conformational changes undergone by bAnc1p. This paper describes the first study of bAnc1p using HDX-MS. Results obtained with the CATR-bAnc1p complex were fully in agreement with published results, thus, validating our approach. On the other hand, the HDX kinetics of the two complexes displays marked differences. The bongkrekic acid-bAnc1p complex exhibits greater accessibility to the solvent on the matrix side, whereas the CATR-bAnc1p complex is more accessible on the intermembrane side. These results are discussed with respect to the structural and biochemical data available on Ancp.

    The AREVA group's backlog reached a record level of euro 39.834 billion as of December 31, 2007, up by 55% from that of year-end 2006. In Nuclear, the backlog was euro 34.927 billion at year-end 2007 (+58%), due in particular to the signature of a contract in a record amount with the Chinese utility CGNPC. The series of agreements concluded provide among other things for the construction of two new-generation EPR nuclear islands and the supply of all of the materials and services needed for their operation through 2027. CGNPC also bought 35% of the production of UraMin, the mining company acquired by AREVA in August 2007. Industrial cooperation in the Back End of the cycle was launched with the signature of an agreement between China and France. In addition, the group signed several long-term contracts in significant amounts, particularly with KHNP of South Korea, EDF and Japanese utilities. The Transmission and Distribution division won several major contracts in Libya and Qatar at the end of the year approaching a total of euro 750 million. For the entire year, new orders grew by 34% to euro 5.816 billion. The backlog, meanwhile, grew by 40% to euro 4.906 billion at year-end. The group cleared sales revenue of euro 11.923 billion in 2007, up by 9.8% (+10.4% like-for-like) in relation to 2006 sales of euro 10.863 billion. Sales revenue for the 4. quarter of 2007 rose to euro 3.858 billion, for growth of 16.7% (+18.8% like-for-like) over one year. Sales revenue for the year was marked by: - Growth of 7.6% (+10.6% like-for-like) in Front End sales revenue, which rose to euro 3.140 billion. The division's Enrichment operations posted strong growth. - Sales were up by 17.5% (+15.2% like-for-like) to euro 2.717 billion in the Reactors and Services division. Sales revenue was driven in particular by the growth of Services operations, after weak demand in 2006, by progress on OL3 construction, and by the start of Flamanville 3, the second EPR. For the Back End division, sales revenue was down by 8.9% (-8.3% like-for-like) to euro 1.738 billion due to staggered production in the Treatment business. For the Transmission and Distribution division, sales were up by 16.2% (+16.7% like-for-like) to euro 4.327 billion, continuing the positive performance of the past several quarters in the Products and Systems businesses, particularly in the Middle East, Asia and Europe. The group once again expects strong growth in its backlog and in sales revenue in 2008.

The following are treated successively: a) the data obtained from measurements of free water clearance and their interpretation; b) the data provided by nephron morphology and the comparative anatomy of the kidney ; c) the data relative to the existence of an intrarenal osmotic gradient; d) the principle of concentration multiplication by a counter current technique; e) the present day theory of counter current concentration of urine, and f) the physiological check on dilution and concentration mechanisms in urine. Lastly, the advantages of the modern theory and the unknown factors which remain are discussed.

    Gallay, Sylvain

    Dans le processus de developpement d'avion, la solution retenue doit satisfaire de nombreux criteres dans de nombreux domaines, comme par exemple le domaine de la structure, de l'aerodynamique, de la stabilite et controle, de la performance ou encore de la securite, tout en respectant des echeanciers precis et minimisant les couts. Les geometries candidates sont nombreuses dans les premieres etapes de definition du produit et de design preliminaire, et des environnements d'optimisations multidisciplinaires sont developpes par les differentes industries aeronautiques. Differentes methodes impliquant differents niveaux de modelisations sont necessaires pour les differentes phases de developpement du projet. Lors des phases de definition et de design preliminaires, des methodes rapides sont necessaires afin d'etudier les candidats efficacement. Le developpement de methodes ameliorant la precision des methodes existantes tout en gardant un cout de calcul faible permet d'obtenir un niveau de fidelite plus eleve dans les premieres phases de developpement du projet et ainsi grandement diminuer les risques associes. Dans le domaine de l'aerodynamisme, les developpements des algorithmes de couplage visqueux/non visqueux permettent d'ameliorer les methodes de calcul lineaires non visqueuses en methodes non lineaires prenant en compte les effets visqueux. Ces methodes permettent ainsi de caracteriser l'ecoulement visqueux sur les configurations et predire entre autre les mecanismes de decrochage ou encore la position des ondes de chocs sur les surfaces portantes. Cette these se focalise sur le couplage entre une methode d'ecoulement potentiel tridimensionnelle et des donnees de section bidimensionnelles visqueuses. Les methodes existantes sont implementees et leurs limites identifiees. Une methode originale est ensuite developpee et validee. Les resultats sur une aile elliptique demontrent la capacite de l'algorithme a de grands angles d'attaques et dans la region post

    Le sujet de cette these concerne la problematique de fonctionnement et de selection des appareils a mise et remise a roue a godets dans les systemes de manutention des materiaux en vrac a grande echelle. Premierement, une etude bibliographique a ete effectuee. En se basant sur les lacunes dans les connaissances du domaine analyse, les objectifs de la recherche ont ete definis. Ils sont divises en trois parties: (1) Developper une methodologie du calcul de la capacite des machines en operation de reprise refletant les relations entre les caracteristiques de l'equipement et les parametres de son environnement de travail. (2) Developper un critere d'evaluation du niveau technique de ces machines. (3) Definir les relations entre la machine et les parametres du materiau empile lors de l'operation du stockage. La premiere etape de recherche consiste en la creation d'une base de donnees concernant les parametres de construction et de travail de ces machines. Les donnees des fiches techniques sont souvent presentees de facon variee et incomplete et la recherche a ete orientee vers l'unifonnisation des donnees. Dans la seconde phase, une fonction de vitesse de balayage de la fleche est definie. Elle est basee sur la forme particuliere du materiau empile en stock et la geometrie de travail des machines. Cette fonction sert comme base pour l'elaboration d'une methodologie precise de calcul de la capacite de ces appareils en operation de reprise. Le resultat final rencontre cet objectif. La troisieme partie concerne lelaboration d'un modele d'evaluation du niveau technique de ces machines en se basant sur une analyse statistique et correlationnelle de leurs parametres techniques se trouvant dans la base de donnees. Ces resultats, jumeles avec les parametres economiques (cout de possession et d'operation), servent de base pour la formulation d'un coefficient de niveau technique. Dans la demiere etape, un modele definissant l'operation de ces appareils en stockage a ete

  1. Application of Inversion to Integrated Stratigraphic Interpretation Application de l'inversion pour l'interprétation stratigraphique intégrée

    Dequirez P. Y.

    2006-11-01

    Full Text Available The EAEG Inversion Workshop consisted of a calibrated stratigraphic study of a carbonate reservoir through different inversion techniques. Information was provided by one poststack seismic section and an impedance log from a well on the seismic line to calibrate the seismic data. From the interpreter's point of view, the objective was to pursue a hopefully oil productive zone in the carbonate reservoir through the lateral delineation of the estimated pseudo-impedances. The advanced integrated stratigraphic interpretation software INTERWELL has been developed to achieve calibration and integration of impedance well logs, seismic data and stratigraphic information. The complete procedure was demonstrated for the workshop test line to solve the well extrapolation problem. Firstly, an interpretive well-to-seismic tie procedure was applied for wavelet estimation and log editing. Then the available impedance well log and interpretive knowledge were integrated with the seismic data by using an inversion method with a priori information. The use of a priori information reduces the range of models to be consistent with the observed seismic data and ensures that the results are geologically meaningful. This advantage is best understood by considering three extreme approaches starting without constraints, then applying them more strongly. From our assumptions about the information content in the workshop dataset, we derived an optimal impedance section which facilitates the interpretation. The estimated pseudo-logs match those observed at three blind wells unavailable prior to the workshop. Le workshop sur l'inversion organisé à l'EAEG (European Association of Exploration Geophysicists avait pour but l'étude stratigraphique comparative d'un réservoir carbonaté à l'aide de différentes techniques d'inversion.

    density expected at depth in the same formation. Furthermore, rock mechanics helps in understanding the fracturation state at depth to identify the predominant fractures in regard to the interpretation of seismic anisotropy in terms of fluid substitution inside the fracture network. Le monitoring des sites de stockage de CO2 dans des réservoirs fracturés (champs d’hydrocarbures déplétés ou aquifères salins profonds nécessite de prendre en compte l’impact de la fracturation et la substitution de fluides sur la réponse sismique. Les données sismiques peuvent fournir des informations sur la souplesse additionnelle due à la présence de fractures et de fluides à travers l’analyse de l’anisotropie sismique azimutale avec un modèle de physique des roches adapté. Nous introduisons un modèle de physique des roches construit en collaboration avec des géologues qui fournit une description réaliste des milieux fracturés. Ce modèle concerne des milieux géologiques fracturés en présence de fluides et qui sont caractérisés par un certain degré de porosité matricielle, la présence de plusieurs familles de fractures connectées ou non avec la porosité matricielle et l’existence d’une anisotropie intrinsèque. L’application directe de ce modèle montre que la valeur de l’anisotropie des ondes P mesurée à partir de données sismiques peut être expliquée par plusieurs jeux de paramètres parmi lesquels la densité de fractures, la souplesse du fluide interstitiel ou la porosité. La présence d’une anisotropie inhérente modifie également l’anisotropie des ondes P et, par conséquent, l’interprétation de sa valeur en termes de substitution fluide dans un milieu poreux fracturé. En ce qui concerne le monitoring de la substitution fluide, si des données sismiques sont acquises avant et après cette substitution, la modification du niveau d’anisotropie des ondes P peut être liée au changement de souplesse du contenu fluide dans le

    Microplastics are widespread in aquatic environments and can be ingested by a wide range of organisms. They can also be transferred along food webs. Estuaries and other tidal wetlands may be particularly prone to this type of pollution due to their particular hydrological characteristics and sewage input, but few studies have compared wetlands with different anthropogenic pressure. Furthermore, there is no information on microplastic transfer to secondary intertidal consumers such as shorebirds. We analysed intertidal sediments, macroinvertebrates and shorebirds, from three important wetlands along the Eastern Atlantic (Tejo estuary, Portugal; Banc d'Arguin, Mauritania and Bijagós archipelago, Guinea-Bissau), in order to evaluate the prevalence and transfer of microplastics along the intertidal food web. We further investigated variables that could explain the distribution of microplastics within the intertidal areas of the Tejo estuary. Microfibers were recorded in a large proportion of sediment samples (91%), macroinvertebrates (60%) and shorebird faeces (49%). μ-FTIR analysis indicated only 52% of these microfibers were composed of synthetic polymers (i.e. plastics). Microfiber concentrations were generally higher in the Tejo and lower in the Bijagós, with intermediate values for Banc d'Arguin, thus following a latitudinal gradient. Heavier anthropogenic pressure in the Tejo explains this pattern, but the relatively high concentrations in a pristine site like the Banc d'Arguin demonstrate the spread of pollution in the oceans. Similar microfiber concentrations in faeces of shorebirds with different foraging behaviour and similar composition of fibres collected from invertebrate and faeces suggest shorebirds mainly ingest microfibers through their prey, confirming microfiber transfer along intertidal food webs. Within the Tejo estuary, concentration of microfibers in the sediment and bivalves were positively related with the percentage of fine sediments and

  4. Governo das sociedades, custos de agência e crise financeira: que relação?

    Directory of Open Access Journals (Sweden)

    Catarina Alexandra Alves Fernandes

    2014-03-01

    Full Text Available O debate sobre o governo das sociedades tem ganhado crescente relevo nos meios acadêmico e empresarial desde o fim da década de 1980. Esse maior destaque foi originado por diversos fatores, dos quais se salientam a crise na Ásia, os escândalos financeiros que assolaram grandes empresas cotadas norte-americanas e algumas empresas de auditoria e, mais recentemente, a crise financeira mundial. Embora há muito defendida a necessidade de aperfeiçoar os instrumentos existentes e de descobrir novos mecanismos, de modo a encontrar um sistema de governo das sociedades que minimize os custos de agência, a crise financeira mundial com origem nos EUA veio dar-lhe novo “fôlego”. E, agora, com especial ênfase na banca. Falhas no governo das sociedades, em particular no setor bancário, têm sido apontadas como culpadas pela crise financeira global iniciada em 2007, só comparável à Grande Depressão. Assim, este artigo pretende, em primeiro lugar, apresentar uma caracterização genérica dos mecanismos de governo das sociedades, integrando no estudo os denominados custos de agência e, em seguida, analisar tais mecanismos no setor bancário, estabelecendo uma relação entre eles e a crise financeira. A pesquisa efetuada permite demonstrar a importância dos instrumentos de governo das sociedades na minimização dos custos de agência, nomeadamente no contexto da crise financeira. Ainda que o setor bancário tenha as suas especificidades, a investigação feita indica que existe uma relação entre aqueles instrumentos e a performance dos bancos e que fragilidades no governo das sociedades determinaram em larga medida a crise financeira.

    Full Text Available O presente trabalho apresenta um modelo teórico de quatro setores que endogeiniza o setor financeiro da economia submetendo-o às decisões das famílias e do governo. Como resultado, temos que as variáveis monetárias taxa de juros, política de reservas bancárias e imposto inflacionário influenciam o crescimento econômico. Essa relação foi estimada para a economia brasileira a partir da metodologia de Vetores Auto-Regressivos (VAR e dos testes de exogeneidade fraca e forte. Esses testes revelaram que a taxa de juros e o imposto inflacionário possuem uma relação endógena com a taxa de crescimento da economia e afetam somente a sua variabilidade. No entanto, a política de reservas bancárias apresentou-se como exógena, tendo efeitos permanentes sobre essa mesma taxa. Em resumo, a política de reservas bancárias determina o montante de empréstimos da economia, que conseqüentemente influencia o crescimento econômico. Nossas estimações indicaram que a elevação em 10 pontos percentuais na alíquota de reservas bancárias reduz a taxa de crescimento da economia em até 1,2%.The objective of this paper is to build a four sector model that make the financial sector endogenous and under the influence of families and government policies. As a result, the long run economic growth is influenced by monetary variables like the size of bank reserves, interest rates and inflationary tax. This model was empirically estimated through Auto-regressive Vector (VAR and submitted to exogeneity tests. The results were that interest rate and inflationary tax are endogenously related to economic growth and affect only its variability. However, the bank reserve policy is exogenous to this variable and showed to have permanent effect on it, more specifically, in sum, the reserve bank policy set the amount of loan in the economy and it influences economic growth. Our estimation indicates that the rise of the bank reserve in 10 points might reduce the

    Full Text Available O levantamento das taxas de retorno históricas de algumas das maiores corporações bancárias brasileiras chama a atenção, pois das três instituições pesquisadas, Itaú, Bradesco e Unibanco, duas delas apresentaram historicamente evolução nos preços de suas ações. Enquanto a outra apresentou um nível histórico constante em termos do preço de sua ação. Os valores de betas calculados para todas as corporações mantiveram-se em termos médios, constantes. Este valor de beta foi calculado com base em dados semestrais no decorrer de janeiro de 1995 a junho de 2003. Assim, com base nas informações levantadas e apresentadas neste trabalho, a seguinte questão é abordada: existe relação entre os retornos históricos das ações das corporações do setor bancário com o beta de suas ações? Por meio de um conjunto de dados históricos e análises estatísticas, procurou-se verificar se a observações realizadas por Fama e Kenneth quanto à inexistência de relação entre retorno histórico e betas também se aplica ao setor bancário brasileiro. Conclui-se que, embora o setor financeiro bancário do Brasil seja relacionado fracamente às oscilações de mercado, as instituições financeiras brasileiras, a exemplo das observações realizadas por Fama e Kenneth, também não apresentam evidências de que os retornos históricos das ações estejam relacionados com os valores de beta das ações.

    L'objectif principal de cette recherche est la mise au point d'une architecture d'integration de donnees socio-bio-geographiques et de donnees satellitales dans un Systeme d'Information Geographique (SIG) en vue d'une aide a la prise de decisions dans un environnement semi-aride au nord du Burkina Faso. Elle repond a la question fondamentale de l'interpretation des effets des facteurs climatiques et socioeconomiques sur le milieu pastoral. La recherche s'est appuyee sur plusieurs hypotheses de travail: possibilite d'utilisation de modele de simulation, d'approche multicritere et de donnees de teledetection dans un cadre de systeme d'information geographique. L'evolution spatiotemporelle des parametres de productivite du milieu a ete evaluee par approche dynamique selon le modele de Wu et al. (1996) qui modelise les interactions entre le climat, le milieu physique, le vegetal et l'animal pour mieux quantifier la biomasse primaire. A ce modele, quatre parametres ont ete integres par approche floue et multicritere afin de prendre en compte la dimension socioeconomique de la productivite pastorale (apport majeur de la recherche): la sante, l'education, l'agriculture et l'eau. La teledetection (imagerie SPOT) a permis de definir la production primaire a partir de laquelle les simulations ont ete realisees sur 10 annees. Les resultats obtenus montrent une bonne correlation entre biomasse primaire in situ et celle calculee pour les deux modeles, avec toutefois une meilleure efficacite du modele modifie (4 fois plus) dans les zones de forte productivite ou l'on note un taux de surexploitation agricole eleve. A cause de la variabilite spatiale de la production primaire in situ, les erreurs des resultats de simulation (8 a 11%) sont acceptables et montrent la pertinence de l'approche grace a l'utilisation des SIG pour la spatialisation et l'integration des differents parametres des modeles.

A perspectiva funcionalista orienta uma crítica ao papel que as instituições financeiras assumiram num contexto de crise econômica cujas origens estão, segundo autores, na forte desregulação financeira e no seu descasamento do setor produtivo. No cenário nacional, a perspectiva funcionalista apresentada possibilita uma crítica ao manejo disfuncional das instituições públicas de fomento (sobretudo, o BNDES, propiciadas pelo sigilo bancário, bem como se cogita de uma função negativa de tais instituições, derivada da solução proposta para essa mencionada disfuncionalidade   afastamento irrestrito do sigilo bancário em operações conduzidas por bancos públicos de fomento.

A avaliação da confiabilidade simples e composta mostrou que o instrumento desenvolvido é adequado, podendo ser utilizado em pesquisas futuras.

  8. A New Online Secondary Path Modeling Method with An Auxiliary Noise Power Scheduling Strategy for Narrowband Active Noise Control Systems

    Directory of Open Access Journals (Sweden)

    Chao Sun

    2017-11-01

    Full Text Available In recent years, the online secondary path modeling (SPM method with an auxiliary noise power scheduling strategy has been crucial for active noise control (ANC systems and has also become a popular research topic. However, most scheduling strategies have been designed for broadband active noise control (BANC, and these ideas may not be directly applied to narrowband active noise control (NANC systems due to the difference in structure between BANC and NANC systems. In this paper, a new online SPM method with auxiliary noise power scheduling is proposed. Here, the controlled system is adapted using the filtered-x weighted accumulated least mean square (FXWALMS algorithm proposed by the authors. Moreover, the auxiliary noise power is scheduled based on the convergence status of the forgetting factor to accurately track the change in the NANC system. As a result, the proposed method not only achieves good modeling accuracy and fast convergence but also considerably increases noise attenuation. Extensive simulations are conducted to prove the superior performance of the proposed method in various scenarios.

    Full Text Available Les émissions de polluants d'un véhicule ont été modélisées avec l'hypothèse que le comportement du moteur peut se prévoir sur le véhicule à partir de mesures établies au banc moteur pour des points stabilisés. Cette méthode, déjà utilisée avec succès pour la modélisation des consommations, s'est montrée satisfaisante pour la prévision des émissions lors de la plupart des modes de fonctionnement du véhicule, seules certaines périodes transitoires ont nécessité des hypothèses et des mesures complémentaires. Le modèle a été testé en adaptant sur des véhicules des moteurs dont les émissions avaient été préalablement relevées au banc, puis en mesurant les effluants du véhicule sur banc à rouleaux pour des parcours du type cycles normalisés. De cette manière un bon accord s'est révélé entre les mesures et les calculs utilisant les données établies au banc moteur, les écarts étant d'environ 10 % en ce qui concerne les émissions d'hydrocarbures imbrûlés, et de 4 % pour l'oxyde de carbone et les oxydes d'azote. Ces écarts ont paru satisfaisants, comparés à la précision que l'on constate habituellement sur les mesures tant sur le véhicule qu'au banc moteur. A model for simulating pollutant emissions by automotive vehicles has been worked out and is based on the assumption that the engine behavior of the vehicle can be forecast from measurements made on a test bench under steady running conditions. This method has already been successfully tested for modeling consumption. It has also proved satisfactory for simulating emissions during most vehicle running conditions. Some transient phases were the only times when supplementury assumptions and measurements were required. The model was tested by equipping vehicles with engines whose emissions had previously been determined on a test bench. The pollutant were measured for a vehicle on a roller test bench for trips ot the standardizet cycletype and then

    properties are preserved during the deformation process. These different steps are demonstrated on a realistic synthetic case. Que ce soit pour la production de pétrole ou le stockage de CO2, le terme réservoir est utilisé régulièrement. Un réservoir désigne une structure géologique hétérogène en types de roches ou en termes de propriétés de perméabilité et de porosité. Dans le domaine pétrolier, de nombreux réservoirs présentent des fractures ou des failles. Les réservoirs fracturés occupent une part importante de la production de pétrole dans le monde (Moyen Orient, Golfe du Mexique, etc.. Malgré la présence de fractures, ces réservoirs n’en restent pas moins de bons réservoirs. Des études de réservoirs dédiés au stockage de CO2 ont montré de plus la présence de fractures diffuses ou de failles ainsi qu’un fort impact de celles-ci dans le transfert du CO2. Un facteur clé de la connaissance des réservoirs fracturés est la compréhension de la géométrie et de la conductivité hydraulique du réseau formé par les fractures. Cette compréhension nécessite la construction d’un modèle de réservoir intégrant l’ensemble des connaissances conceptuelles et des données disponibles sur le terrain. Le présent article expose une méthodologie permettant d’effectuer un calage d’historique d’un modèle réservoir par la modification des propriétés et de la géométrie d’un réseau de failles sub-sismiques. Un modèle original de réseau de failles sub-sismiques est présenté. Il est fondé sur une caractérisation fractale de la géométrie du réseau des failles à partir des données sismiques ou des affleurements. Ce modèle peut être simulé en étendant l’organisation du réseau des failles sismiques à l’échelle inférieure des failles sub-sismiques. Le réseau de failles obtenu peut alors être déformé de façon à refléter le comportement hydrodynamique du réservoir. Cette propriété permet d’effectuer le

Cette recherche s'est inscrite dans un paradigme pragmatique de recherche. Le pragmatisme a guide nos choix en ce qui a trait au modele de recherche et des techniques utilisees. Cette recherche a associe a la fois des techniques qualitatives et quantitatives, particulierement en ce qui concerne la collecte et l'analyse de donnees. Les donnees recueillies dans la premiere etape de l'evaluation de l'utilisabilite et de la convivialite du materiel par les enseignantes et les enseignants de sciences et les filles ont revele que le materiel concu est tres utilisable et convivial. Toutefois quelques petites ameliorations seront apportees a une version subsequente afin de faciliter davantage la navigation. Quant a l'evaluation des effets du materiel concu sur les variables reliees au sentiment d'auto-efficacite et aux interets lors de l'etape quasi experimentale, nos donnees qualitatives ont indique que ce materiel a eu des effets positifs sur le sentiment d'auto-efficacite et sur les interets des filles qui l'ont utilise. Toutefois, nos donnees quantitatives n'ont pas permis d'inferer un lien causal direct entre l'utilisation du materiel et l'augmentation du sentiment d'auto-efficacite et des interets des filles en sciences et en TIC.

    When the temperature of a conductor is lowered, its resistance decreases appreciably. This fact can be made particular use of in the production of high magnetic fields, to reduce the total energy consumed for a given coil. In this paper the problem of the evacuation of heat is examined, and the various fluids which can be used are compared from the viewpoint of the maximum fields attainable from them for a given coil. These fluids are: - water (nucleate boiling); - liquid nitrogen; - liquid hydrogen; - helium at a temperature of 20 deg. K; - helium at a temperature of 10 deg. K. First of all a method for calculating the quantities of heat evacuated by a fluid is established, using general equations for fluid flow with heat exchange.

Dans ce qui suit, le probleme de l'evacuation des pertes Joules est examinee et les differents fluides utilisables sont compares du point de vue des champs maximum qu'ils permettent d'atteindre pour une bobine donnee. Ces fluides sont: - l'eau (nucleate boiling); - l'azote liquide; - l'hydrogene liquide; - l'helium a une temperature de 20 deg. K; - l'helium a une temperature de 10 deg. K. Au prealable une methode de calcul des quantites de chaleur evacuee par un fluide est etablie, a partir des equations globales de dynamique des fluides avec echange de chaleur. (auteur)

    Les informations sur les pratiques de conservation des sols comme le labourage et la gestion des residus de culture sont requises afin d'estimer avec exactitude les risques d'erosion des sols. Quoique les micro-ondes soient sensibles aux conditions d'humidite et aux proprietes geometriques des surfaces, il n'en demeure pas moins que l'on connait encore peu sur la sensibilite des micro-ondes polarisees lineaires ou des parametres polarimetriques du ROS en fonction des caracteristiques des residus. A partir de donnees prises a l'aide d'un diffusometre monte sur un camion en 1996 et lors d'une mission SIR-C menee en 1994, cette recherche a demontre que les micro-ondes sont sensibles a la fois a la quantite et au type de couverture de residus, de meme qu'a la teneur en eau des residus. La reponse des polarisations croisees lineaires et de plusieurs parametres polarimetriques, incluant la hauteur pedestre, a permis d'observer qu'une diffusion volumique importante avait lieu en presence de vegetation senescente qui se tenait debout et pour les champs non laboures. La diffusion de surface dominait cependant pour les champs avec de faibles quantites de residus et des residus plus fins. La recherche a toutefois demontre que des conditions de surface complexes etaient crees par differentes combinaisons de residus et de pratiques de labourage. Par consequent, il faudra attendre que des donnees multi-polarisees ou polarimetriques soient acquises par les capteurs prevus a bord du satellite canadien RADARSAT-2 et du satellite ENVISAT de l'Agence spatiale europeenne avant de pouvoir completement caracteriser les champs apres la recolte.

After a short introduction on conventional imaging techniques, we describe two observations that demonstrate the presence of multiple scattering in seismic records: the equipartition principle, and the coherent backscattering effect (Chap. 2). Multiple scattering is related to the mesoscopic nature of seismic and acoustic waves, and is a strong limitation for conventional techniques like medical or seismic imaging. In the following part of the manuscript (Chaps. 3 5), we present an application of mesoscopic physics to acoustic and seismic waves: the principle of passive imaging. By correlating records of ambient noise or diffuse waves obtained at two passive sensors, it is possible to reconstruct the impulse response of the medium as if a source was placed at one sensor. This provides the opportunity of doing acoustics and seismology without a source. Several aspects of this technique are presented here, starting with theoretical considerations and numerical simulations (Chaps. 3, 4). Then we present experimental applications (Chap. 5) to ultrasound (passive tomography of a layered medium) and to seismic waves (passive imaging of California, and the Moon, with micro-seismic noise). Physique mésoscopique des ultrasons et des ondes sismiques : application à l'imagerie passive. Cet article de revue rassemble plusieurs aspects fondamentaux et appliqués de la propagation des ondes acoustiques et élastiques dans les milieux hétérogènes, en régime de diffusion simple ou multiple. Après une introduction sur les techniques conventionelles d'imagerie sismique et ultrasonore, nous présentons deux expériences qui mettent en évidence la présence de diffusion multiple dans les enregistrements sismologiques : l'équipartition des ondes, et la rétrodiffusion cohérente (Chap. 2).

    Full Text Available The main features of wave propagation in gyrotropic media are compared with wave propagation in anisotropic media. The results of numerical modelling are presented for three typical seismic exploration models. The first two models are azimuthally anisotropic media (of orthorombic symmetry system, group 2m without and with gyration. The third model is a gyrotropic transversely isotropic medium with a vertical symmetry axis. The computations have been made for propagation of shear waves along the vertical symmetry axis. For sufficiently short wave paths (in our models less than 400 m the two-component (x, y seismograms are similar for all three models. For longer paths both signal shape and signal duration for the first and the third model differ noticeably. Some evidence (experimental data and a micromodel is given to show that the gyrotropy of rocks does exist or, at least, can exist. Les principales caractéristiques de la propagation des ondes dans les milieux gyrotropes sont comparées avec la propagation des ondes dans les milieux azimutalement anisotropes. Les résultats d'une modélisation numérique sont présentés pour trois modèles caractéristiques d'exploration sismique. Les deux premiers modèles sont des milieux anisotropes (de symétrie orthorhombique, groupe 2m avec et sans gyrotropie. Le troisième modèle est un milieu gyrotrope transverse isotrope avec un axe de symétrie vertical. Ces calculs ont été réalisés pour la propagation des ondes transversales le long de l'axe de symétrie vertical. Pour des trajets sismiques suffisamment courts (pour nos modèles, moins de 400 m, les sismogrammes à deux composantes (x, y sont similaires pour les trois modèles. Pour des trajets plus longs, la forme et la durée du signal diffèrent sensiblement pour les modèles 1 et 3. Ceci a pour but de montrer (à l'aide des données expérimentales et d'un micromodèle que la gyrotropie dans les roches existe, ou, tout au moins, peut

  1. Mudança no Critério de Contabilização de Investimentos Financeiros: Estudo de Evento sobre Títulos Soberanos da Grécia

    Full Text Available A alteração feita pelo IASB, em 2008, na classificação dos instrumentos financeiros para reduzir as perdas bancárias com a crise do subprime e de títulos soberanos dos países-membro da União Europeia, após um pedido protocolado pela Comissão da União Europeia, motivou esta pesquisa. A referida alteração ensejou a mudança do critério de avaliação, que passou de valor justo para custo amortizado para os instrumentos reclassificados, muito embora alguns bancos não tenham aderido à reclassificação, mantendo a orientação original que determinava a avaliação pelo valor justo. Embora a alteração tenha colaborado para que as instituições bancárias protelassem essas perdas no resultado contábil, a mesma não afetou os fluxos de caixa futuros. Por meio de Estudo de Evento, esta pesquisa objetivou testar a Hipótese de Eficiência de Mercado - HEM, analisando 33 instituições bancárias detentoras de títulos soberanos gregos. Como evidenciam os resultados da pesquisa, o mercado foi equitativo com essas instituições, penalizando-as com base no grau de exposição aos títulos gregos, independentemente do critério utilizado, corroborando a HEM: o valor de um ativo é o valor presente dos fluxos de caixa futuros e não dos lucros. Nesse sentido, a contribuição desta pesquisa se revela na oportunidade de, mais uma vez, testar-se a HEM em relação à adoção ou não de procedimentos contábeis que alteram o resultado sem alterar os fluxos futuros de caixa. Uma consequência importante foi que os governos, por meio da terceira revisão do Acordo de Capital de Basileia, adotaram medidas para regulamentar com mais rigor as instituições financeiras no intuito de que essas instituições, futuramente, possam suportar melhor os efeitos de uma crise financeira.

The claims at issue in U.S. Patent No. 6,258,540 (“US ’540 patent”) are directed to methods of genetic testing by detecting and amplifying paternally inherited fetal cell-free DNA (cffDNA) from maternal blood and plasma. Before the development of this non-invasive prenatal...... diagnostic test, patients were placed at higher risk and maternal plasma was routinely discarded as waste. A reluctant CAFC formulaically interpreted the Supreme Court-devised bifurcated test to identify patent ineligible subject matter and invalidated the patent for this ground-breaking method.

    The ''salting in'' effect of rhodanides of Group 2 metals (magnesium, calcium, strontium, barium) on aqueous-amine solutions (water-aniline, and water-o-toluidine systems) is studied. The solubility in these systems has been determined by the isothermal method at 25 deg C. Compositions of the co-existing liquid phases have been determined by refractometry. The phase diagrams of water-aniline-rhodanide of magnesium, calcium and strontium systems have the same qualitative view. These rhodanides ''salt in'' the water-aniline system so strongly that the systems are completely homogenized. According to the decreasing homogenization effect on the water-aniline and water-o-toluidine systems the salts may be arranged into the following series Mg(NCS) 2 >Ca(NCS) 2 >Sr(NCS) 2 >Ba(NCS) 2 . The ''salting in'. effect is weaker in the water-o-toluidine system rather than in the water-aniline one

    Full Text Available In this work the uncopled thermoelastic model based on the Dual Phase Lag (DPL heat conduction equation is used to investigate the thermoelastic properties of a semi-infinite medium induced by a homogeneously illuminating ultrashort pulsed laser heating. The exact solution for the temperature, the displacement and the stresses distributions ob- tained analytically using the separation of variables method (SVM hybrid with the source term structure. The results are tested numerically for Cu as a target and pre- sented graphically. The obtained results indicate that at very small time duration distur- bance by the pulsed laser the behavior of the temperature, stress and the displacement distribution have wave like behaviour with finite speed.

    1985-11-01

    The first paper is one contribution to a joint study program in the numerical processing of accelerograms from strong earthquakes. A method is proposed for generating an analytic signal having characteristics similar to those of an actual ground displacement. From this signal, a simulated accelerogram is obtained analytically. Various numerical processing techniques are to be tested using this signal: the ground displacements they yield will be compared with the original analytic signal. The second contribution deals with a high-performance digitization complex, custom-designed to stringent technical criteria by the CISI Petrole Services, which has recently been put into service at the Bureau d'Evaluation des Risques Sismiques pour la Surete des Installations Nucleaires. Specially tailored to cope with the problems raised by the sampling of Strong-Motion photographic recordings, it offers considerable flexibility, due to its self-teaching conception, constant monitoring of the work ongoing, and numerous preprocessing options. In the third contribution, a critical examination of several processing techniques applicable to photographic recordings of SMA-1 type accelerometers is conducted. The basis for comparison was a set of two accelerograms drawn from synthetic signals, the characteristics of which were already well known

    Full Text Available Un inventaire exact des gîtes de houille était lié à la réorganisation des rapports de propriété dans la région de la Ruhr (Fondation de la Ruhrkohle AG. Du fait que dans les domaines de gîtes de houille en exploitation les réserves de houille ne suffiront pas à assurer à long terme un rendement d'extraction suffisant, on commença une vaste exploration dans des parties de quartier encore inconnues. Il fut ainsi possible d'élargir considérablement les connaissances sur la situation géologique des gîtes de houille grâce à des études par réflexion sismique, des forages profonds et des enregistrements de forages géophysiques. An accurate inventory of the coal beds was dependent upon the reorganization of property reports in the Ruhr region (Ruhrkohle Fondation AG. Because the working coal fields do not contain sufficient coal reserves to guarantee satisfactory productivity rates on a long-term basis, extensive exploration in previously unexplored parts of the area was undertaken. Thus, it became possible to extend considerably our knowledge of the geological structure of the coal beds through refraction shooting, deep drilling, and the well logging.

    Full Text Available Neste artigo, apresentam-se as perspectivas e os desafios dos bancos no futuro. Com o referencial teórico sobre o tema, construiu-se um questionário para identificar o grau de importância atribuído a 20 diferentes questões. Na pesquisa de campo, abarcaram-se 93 bancários dos níveis gerencial e operacional dos principais bancos brasileiros e 9 professores universitários especialistas em mercado financeiro. Os dados coletados foram analisados estatisticamente usando-se o software Statistical Package for the Social Sciences, versão 13.0. Observando-se as principais conclusões da amostra, não há diferença estatística entre os funcionários dos bancos pesquisados, mas o mesmo não ocorreu entre bancários e professores. Algumas variáveis apresentaram maior relevância: combate às fraudes, business intelligence, bancarização e atendimento rápido. A partir da análise fatorial, identificaram-se seis fatores: sustentabilidade e papel do Brasil; mobilidade e segurança; regulação e novas tecnologias; globalização, inserção e privacidade; atendimento inteligente e bancarização. Pela análise discriminante, classificaram-se corretamente 79,3 e 66,7% dos funcionários do Bradesco e do Banco do Brasil, respectivamente, e 78,8% dos gerentes.

    Full Text Available O que se analisa neste artigo é como os sindicatos dos bancários, metalúrgicos e trabalhadores em telecomunicações têm negociado o (desemprego, a demanda por qualificação e a remuneração variável. Foram tabuladas/analisadas 3.569 cláusulas de acordos coletivos, e realizadas 26 entrevistas com dirigentes sindicais e empresariais em três Estados (RJ, SP e MG. Os resultados indicam que as mudanças organizacionais foram incomparavelmente mais negociadas no setor metalúrgico do ABC. A flexibilização da jornada foi trocada pela redução (da jornada sem redução de salário nos setores metalúrgicos paulistas, mas não em Minas Gerais. No setor bancário, houve poucos resultados nas negociações sobre jornada. As negociações em torno da remuneração variável vinculada às metas das empresas aconteceram nos setores metalúrgicos, e não nos setores de serviços. As entrevistas apontam para um sindicalismo mais propositivo, no sentido de uma intervenção negociada, predisposição que não é correspondida pelos empresários, grosso modo. O Estado, que poderia utilizar seu poder regulador para induzir os empresários a negociarem nessa direção não tem produzido resultados satisfatórios. Conclui-se que não há maturidade empresarial no Brasil que permita ao Estado ausentar-se das relações de trabalho.

Para tanto, realizou-se 12 grupos focais que totalizaram 265 participantes - 134 mulheres e 131 homens - provenientes de uma mesma instituição bancária do setor público. A análise dos resultados seguiu as orientações de Minayo e encontrou respaldo à luz da literatura pertinente que aponta o controle-estimulação, a responsabilização pela conquista e manutenção da beleza física e sua consequente naturalização. Os resultados permitem compreender a beleza física como investimento na carreira, instrumento da gestão gerencialista, definidora da visibilidade/invisibilidade dos corpos, e fonte de sofrimento psíquico. Nesse sentido, a gestão gerencialista se faz notar ao tornar a beleza física rentável. Suas consequências humanas como rejeição, incitação à adesão, impedimentos à ascensão na carreira e sofrimento carecem de divulgação, embora componham o conjunto de elementos relativos à produção de estilos de vida na sociedade líquido-moderna.

  11. Resultados paleomagnéticos de los depósitos pliopleistocenos de la cuenca de Palma (Mallorca, España

    Full Text Available The results from the paleomagnetic analysis of the plio-pleistocene deposits located in the eastern (Bahia Azul Section and western (Banc d'Eivissa borders of the Palma Basin are presented in this paper. The Bahía Azul section is composite by a marine terrace at +70-74 m a.s.1., overlapped by nine littoral dune systems separated by erosional surfaces. The Banc d'Eivissa section is constituted of a lower marine terrace at +24-25 m a.s.l., buried by two dune systems, although there are more numerous in the vicinity. The lithological spectrum at both sections holds a main calcarenitic nature, but the available outcrops display a different degree of weathering making difficult the establishment of a continuous magnetoestratigraphic sequence. The paleontological content (Roselló y Cuerda, 1973 and paleomagnetic results of the Banc d'Eivissa deposits are no sufficient to establish a precise chronological sequence, and only is possible to locate them within the reverse polarity Matuyama epoch. On the contrary, the lower half of the Bahia Azul sequence (marine terrace plus the 3 first dune systems presents a consistent reverse polarity. The paleontological content of these materials indicates an early Pleistocene age (Emilian cycle: Cuerda y Sacarés, 1992 which agree with the obtained paleomagnetic results. Therefore, the whole sequence is interpreted to be located between the normal polarity chrons of Jaramillo and Olduvay (Clr. 1n and C2n of Cande and Kent, 1995 within the Matuyama epoch, but can not be totally rejected the possibility that them could be placed after the Olduvai Chron.Se presentan los resultados paleomagnéticos obtenidos del análisis de los depósitos plio-pleistocenos que afloran en los bordes oriental (sección de Bahía Azul y occidental (Banc d'Eivissa de la cuenca de Palma. La sección de Bahía Azul está constituida por una terraza marina situada a +70-74 metros sobre el nivel medio del mar y, sobre ella, nueve sistemas

    Les materiaux composites avances a matrice polymerique lorsqu'utilises dans des applications structurales aerospatiales sont souvent exposes a des temperatures tres elevees durant de courtes periodes de temps. Ces expositions thermiques peuvent affecter de facon significative leurs proprietes mecaniques. Cette degradation des proprietes suite a la surchauffe est un probleme qui souleve de plus en plus d'inquietude au sein de la communaute aerospatiale. On s'interesse tout autant a la caracterisation de l'endommagement resultant de l'exposition thermique qu'a son evaluation non-destructive. Bien que la technique acousto-ultrasonique semble etre une technique d'evaluation non-destructive toute indiquee pour la detection et la caraterisation de l'endommagement thermique dans les composites avances, il semblerait qu'on ne l'ait pas encore exploitee en ce sens. Cette lacune combinee a l'engagement du Ministere canadien de la defense nationale a developper une technique d'evaluation non-destructive in-situ de l'endommagement thermique de structures composites dans certains avions de chasse de la flotte canadienne constituent la motivation majeure de ce projet de recherche. Cette etude evalue la capacite de la technique acousto-ultrasonique a detecter et quantifier l'endommagement subi par un materiau composite suite a une exposition thermique. Pour parvenir a cet objectif, l'approche de cette etude a ete principalement de nature experimentale. Dans ce contexte, une base importante de donnees acousto-ultrasoniques a ete generee sur des materiaux composites vierges et conditionnes dans le but de correler ces donnees a celles issues des essais mecaniques et des analyses micrographiques et fractographiques. L'evaluation acousto-ultrasonique de la degradation thermique a ete realisee sur des echantillons de resine pure et de composite ayant ete expose a divers conditionnements. De plus, l'evolution de l'endommagement dans des composites vierges et degrades thermiquement a ete

    The authors studied the action of some parameters on the reaction of transformation fibrinogen-fibrin. The five parameters studied are: the concentration of substratum: a certain quantity of enzyme determines an optimum quantity of fibrinogen; the concentration of enzyme: a certain quantity of substratum defines an optimum quantity of enzyme, beyond which the excess of enzyme is unable to act, the substratum being saturated by the enzyme; the concentration of Ca ions: between 0,07 and 0,10 mg of Ca by mg of fibrinogen, the reaction appears with a great speed. Between 0,02 and 0,40 mg of Ca by mg of fibrinogen the fibrin stabilisation is possible, the FSF can act only inside the definite bounds; the ph of the solution: the reaction of the transformation appears with its maximum intensity on physiological ph, the polymerisation is not possible on acid ph; the temperature has an effect which could not really be verified owing to the fact that the technical realisation is difficult. (author) [French] Les auteurs etudient l'action de certains parametres sur la reaction de transformation du fibrinogene en fibrine. Les cinq parametres etudies sont: la concentration du substrat: une quantite d'enzyme donnee determine une quantite optimale de fibrinogene; la concentration en enzyme: une quantite donnee de substrat definit une quantite optimale d'enzyme; au dela de laquelle l'exces d'enzyme ne peut agir, le substrat etant sature en enzyme; la concentration en ions Ca: entre 0,07 et 0,10 m g Ca par mg fibrinogene, la reaction se manifeste a grande vitesse, entre 0,02 et 0,40 mg Ca par mg fibrinogene, la stabilisation de la fibrine est possible. Le FSF ne peut agir que dans les limites definies; le pH du milieu: la reaction de transformation se manifeste avec son maximum d'intensite au pH physiologique. A pH acide, la polymerisation est impossible; la temperature a un effet qui n'a pu etre reellement controle du fait de la difficulte de

    Les resultats au Programme international pour le suivi des acquis des eleves (PISA) demontrent que les jeunes neobrunswickois francophones se classent b un niveau significativement inferieur comparaiivement aux eleves anglophones du Nouveau-Brunswick, aux eleves des autres provinces canadiennes et se classent sous la moyenne internationale de tous les pays participants quant b la culture scientifique. L'evaluation de cette culture scientifique est basee sur une serie de savoirs, de savoir-faire et de savoir-etre reliee au processus d'enquete scolaire. Le processus d'enquete scolaire est une approche b l'apprentissage ou les eleves effectuent des recherches d'informations, discutent d'idees et entreprennent des investigations pour augmenter leur comprehension d'un probleme ou d'un sujet. Les recherches demontrent que le processus d'enquete scolaire est rarement une composante pedagogique importante de la salle de classe et les recherches portant sur l'implantation du processus d'enquete scolaire recommandent de rendre ce dernier plus accessible aux enseignantes et aux enseignants. Afin de rendre le processus d'enquete plus accessible aux enseignantes et aux enseignants, notre recherche porte sur l'evaluation de la valeur pedagogique d'un scenario d'apprentissage (PhaRoboS) concu specialement pour creer un environnement dans lequel les eleves auront plusieurs occasions a mobiliser les habiletes reliees au processus d'enquete. Les retombees de cette evaluation nous permettront d'offrir des pistes de remediations afin d'aider plus d'enseignantes et d'enseignants b creer un environnement dans lequel les eleves auront plusieurs occasions b mobiliser les habiletes reliees au processus d'enquete. Cette evaluation s'est faite a partir d'une methodologie inspiree de l'evaluation pour fin d'amelioration d'un objet pedagogique. L'analyse des donnees qualitatives recueillies aupres des eleves et de leur enseignante d'une ecole francophone du Nouveau-Brunswick semble montrer que

    Collard-Fortin, Ugo

    Le developpement des sciences/technologie a tres clairement contribue a ce que ce dernier domaine de savoirs jouisse d'une place de choix au sein de notre societe. Au-dela des progres de notre civilisation inherents a ce dernier developpement, cette croissance amena avec elle un lot d'ineluctables dommages collateraux, contribuant en corollaire a l'emergence de diverses problematiques environnementales inquietantes pour lesquelles les valeurs ainsi que le mode de fonctionnement de la societe occidentale contemporaine sont largement tributaires. C'est entre autres en reponse a cet etat de fait que la recente vague de reforme de l'Education conduisit a l'integration, dans les curricula de sciences/technologie, de contenus relavant d'education relative a l'environnement (ERE). Face au changement, les enseignants de sciences ont du s'approprier ce nouveau programme afm de l'enseigner a leurs eleves. Toutefois, l'analyse de la situation montre que les prescriptions du programme en matiere d'ERE ne se sont pas toujours traduites en de reelles actions dans la pratique. Le contexte de notre etude s'est interesse aux pratiques educatives de l'ERE ainsi qu'a la representation sociale qui en decoule. Notre recherche aborde plus specifiquement la problematique de la modification de ces derniers objets chez les enseignants de sciences et technologie du deuxieme cycle du secondaire. Pour y arriver, nous avons propose a un groupe de trois praticiens de participer a une activite, en communaute de pratique, de formation continue orientee autour de thematiques ERE. Cette recherche developpement, s'inscrivant dans un paradigme qualitatif/interpretatif, s'est appuyee sur une cueillette de donnees effectuee a partir d'entrevues semi-dirigees, d'observations en situation et d'un groupe de discussion, au debut et a la fm de la formation continue. Les donnees brutes ont ete soumises a une demarche d'analyse inductive et ont genere diverses categories etayant nos objets de recherche

    Selon la presse, dans la guerre des Balkans et bien plus massivement dans la guerre du Golfe, des obus anti- chars ont ete utilises, avec des "charges d'uranium appauvri". La presse a decrit deux types de ces "obus- crayons", l'un de diametre 30 mm et 300 mm de long, avec une charge de 300 g d'uranium et tire par des avions, l'autre de 120 mm de diametre avec une charge de 1 a 5 Kg d'uranium, tire par des chars et donc peu ou pas utilise au Kosovo. Les commentaires ont ete varies. On a parle d'armes atomiques, on a dit que c'etait completement inoffensif ou au contraire tres dangereux. Les elements d'information qui suivent tentent d'eclairer le probleme, car on va montrer que probleme il y a, avec des donnees incontournables. Mais faute d'une enquete approfondie et faute d'informations precises, on conclura aussi avec des questions. Il a semble utile egalement de decrire quelques-unes des realites de la radioactivite et de parler du role particulier de l'uranium 238 pour notre planete.

    The realisation of an NMR spectrometer with a superconducting magnet is presented in the first section. The methods to attain the best possible homogeneity of the magnetic field and to minimize the error in the spectrometer are described. The second section is devoted to the study of elastomers and nitr-oxides free radicals. A shift of the transition temperature with the magnetic field appears for the elastomers. The increasing paramagnetic shift has allowed a complete study by NMR of piperidinic and pyrrolidinic nitroxide free radicals. (author) [French] Dans la premiere partie est exposee la realisation d'un spectrometre de RMN utilisant un solenoide supraconducteur. Des solutions sont donnees pour obtenir la meilleure homogeneite possible du champ magnetique et pour minimiser les sources d'erreur apportees par le spectrometre. La deuxieme partie est consacree a l'etude d'elastomeres et de radicaux libres nitroxydes. Une variation de la temperature de transition avec le champ magnetique est mise en evidence pour les elastomeres. L'accroissement du deplacement paramagnetique a permis une etude complete par RMN des radicaux libres nitroxydes piperidiniques et pyrrolidiniques. (auteur)

    The Astronomical Data Center (ADC) at the NASA Goddard Space Flight Center is a major archive and distribution center for computer-readable versions of astronomical catalogs and journal data tables. The ADC's archives contain more than 1600 catalogs and tables of astrometry, photometry, spectroscopy, radio, high energy, and other miscellaneous data for stellar and non-stellar objects. These data files are documented in a standardized manner, developed in cooperation with the Centre de Donnees astronomiques de Strasbourg (CDS). The ADC's data collection is available via anonymous FTP from node adc.gsfc.nasa.gov in the /pub/adc/archives directory. The holdings can also be accessed from the ADC's WWW site, http://adc.gsfc.nasa.gov/. This site permits users to search the text of the documentation files to locate catalogs and tables of interest or to browse the archives. Hypertext author and keyword indices, and other browsing tools have recently been developed as additional aids to navigating the ADC's large collection of data sets. The ADC is currently developing services to allow researchers to easily locate data fields of interest within files in its archives. The ADC has also prepared three volumes of CD-ROMs that contain several hundred of the largest and most requested catalogs in both ASCII and FITS table formats.

  19. Commande a saturation pour le controle de la position d'un robot volant de type quadrotor =

    Boudguiga, Oussama

    Le quadrotor est un robot volant faisant partie de la famille des multirotors. Il possede plusieurs caracteristiques (une structure de taille reduite, faible poids, agilite, decollage et atterrissage vertical) qui lui offrent plusieurs avantages par rapport a d'autres types de robots volants. Mais malgre tous ses avantages, le quadrotor possede une dynamique fortement non lineaire et pleinement couplee, d'ou la necessite d'une commande robuste et stable. Ce memoire porte donc sur la modelisation et la commande de robot volant de type quadrotor. L'objectif principal dans ce memoire est de concevoir une commande a saturation pour le controle de la position d'un robot volant de type quadrotor. Pour atteindre cet objectif, un modele dynamique du quadrotor selon Euler Lagrange a ete developpe. Ensuite, une approche de commande basee sur une commande a saturation pour le controle de la position et une commande backstepping adaptative pour le controle de l'orientation a ete developpee a partir du modele dynamique. Sa stabilite a ete analysee par la suite en se basant sur le theoreme de Lyapunov et le lemme de Barbalat. L'approche de commande proposee a ete testee avec succes en simulation a l'aide du modele dynamique sur deux scenarios de vol differents, ensuite en ajoutant un bruit blanc dans les donnees de capteurs des positions.

    Although reactor design is mainly governed by deterministic principles in France, the probabilistic approach has been considered an important aid to safety analysis since the early seventies. Various partial probabilistic studies have been performed by Electricite de France, by IPSN and by Framatome, for various types of reactor. In particular, these studies have made it possible to assess the reliability and availability of nuclear power plants safety systems as well as the probability of accident scenarios and have helped to define technical specifications (especially, allowed operating times in the event of a partial unavailability of safety systems). Simultaneously, evaluation methods and corresponding software have been widely developed. Besides. EDF has implemented the Systeme de Recueil de Donnees de Fiabilite - SRDF (Reliability Data Collection System) which allows follow-up of equipment behaviour on all the operating units, and has led to a particularly representative data base. In 1982 the decision was taken at IPSN to carry out a complete PSA for a standard reactor of the 900 MWe type, and in 1986 EDF launched an equivalent study on a 1,300 MWe reactor, taking Unit 3 Paluel as reference. These PSAs were terminated in the course of the first quarter of 1990
