This paper focuses on the variance introduced by the discretization techniques used to handle continuous attributes in decision tree induction. Different discretization procedures are first studied empirically, then means to reduce the discretization variance are proposed. The experiments shows that discretization variance is large and that it is possible to reduce it significantly without notable computational costs. The resulting variance reduction mainly improves interpretability and stability of decision trees, and marginally their accuracy. [less ▲]

Le modèle PEGASE (Planification Et Gestion de l’ASsainissement des Eaux) a été développé afin d'orienter les choix en matière de gestion des eaux de surface par le calcul prévisionnel et déterministe de la qualité des eaux en fonction des apports et rejets polluants, dans des conditions hydrologiques diverses. A la demande de l'Agence de l'Eau Rhin-Meuse, une application de PEGASE a été menée sur le bassin Rhin-Meuse de manière à fournir à l'Agence un outil de gestion de la qualité des eaux de surface et un outil de planification de l'épuration des eaux usées. Dans le cas de l'application de PEGASE au bassin Rhin-Meuse, des simulations générales ont été effectuées pour l'ensemble du bassin (36.000 km², 185 rivières). Ensuite, des sous-bassins particuliers (la Bruche et la Moder) ont été étudiés de manière plus approfondie. Ces simulations ont permis de comparer différents scénarios d'épuration. [less ▲]

The age of a parcel of a constituent of seawater is defined to be the time elapsed since the parcel under consideration left the region where its age is prescribed to be zero. Estimating the age is thus an invaluable tool for understanding complex oceanic flows and the functioning of the numerical models used for representing them. In this paper, a general theory of the age is presented, in which advection, diffusion, production and destruction are properly accounted for. The partial differential equations used for the rigorous computation of the age as a function of space and time are established. This general theory is applied to the computation of the ventilation rates in the World Ocean. The results are compared with those of widely used carbon-14-like dating techniques. Using both numerical simulations and analytical developments, it is shown that the age of the radioactive tracer is smaller than the carbon-14-like age, which is larger than that of the passive tracer. The latter is equivalent to the ventilation or water age. The difference between the various ages, which is essentially due to the influence of mixing processes, increases as the timescale of decay of the radioactive tracer decreases [less ▲]

Proper Orthogonal Decomposition (POD), also known as Karhunen-Loeve decomposition, or principal components analysis (PCA), is emerging as a useful experimental tool in dynamics and vibrations. The POD is a statistical pattern analysis technique for finding the dominant structures in an ensemble of spatially distributed data. These structures can be used as an orthogonal basis for efficient representation of the ensemble. The Proper Orthogonal Modes (POM) have been interpreted mainly as empirical system modes. They have been shown to represent the optimal distributions of kinetic energy or power, and the proper orthogonal values indicate the power associated with these principal distributions. We investigate the use of the proper orthogonal modes of displacements for the identification of parameters of nonlinear dynamical structures with an optimization procedure based on the difference between the experimental and simulated POM. A numerical example of a beam with a local nonlinear component will illustrate the method. [less ▲]

This work deals with the application of the proper orthogonal decomposition (POD) to structural dynamics. On one hand, a physical interpretation of the proper orthogonal modes (POM) is given using the singular value decomposition (SVD). It is shown that the POM converge to the normal modes under some circumstances. On the other hand, the POM are exploited for model reduction purposes. The efficiency of the reduced model for the prediction of the response is tested on a nonlinear beam. The comparison with another reduced model obtained via the normal modes of the linearised system points out that the POM are optimal for the reconstruction of the dynamics of a system. [less ▲]

This paper discusses procedures for nonlinearity detection, localisation and identification in structures from time domain vibration measurements. The detection and the localisation techniques use pattern recognition tools and are based on a dissimilarity measure between the signals coming from a linear structure and the corresponding nonlinear one. The detection procedure distinguishes between linear structures and structures with a nonlinearity employing nearest neighbour techniques. The localisation procedure combines substructuring with a nonlinearity detection procedure. This technique is useful for cases of local nonlinearity, when its localisation can be of value for the consequent understanding and modelling of the structure. The identification procedure makes use of the Karhunen-Loeve transform, known also as Proper Orthogonal Decomposition (POD). It is a powerful tool for solving inverse problems in nonlinear structural dynamics. The identification procedure works on the basis of the minimisation of a difference function between the experimental and the simulated proper orthogonal modes (POM). The proposed techniques are demonstrated on a beam test case with a local damping type nonlinearity. [less ▲]

This paper investigates the use of reinforcement learning in electric power system emergency control. The approach consists of using numerical simulations together with on-policy Monte Carlo control to determine a discrete switching control law to trip generators so as to avoid loss of synchronism. The proposed approach is tested on a model of a real large scale power system and results are compared with a quasi-optimal control law designed by a brute force approach for this system. [less ▲]

A general transient stability control technique is applied to the design of preventive countermeasures consisting of rescheduling generators’ active power. The technique relies on SIME, a hybrid direct–time-domain method; and, like SIME, it preserves the accuracy of time-domain methods and their ability to handle any power system modeling, stability scenario and mode of instability. Its application to generation rescheduling may provide various patterns, able to comply with various operational specifics and strategies, as, for example, congestion management or available transfer capability calculations. The paper suggest how the technique may be shaped to choose automatically rescheduling patterns. A sample of such patterns are illustrated via simulations performed on an EPRI test system. [less ▲]

We generalize the concept of conserving, Phi-derivable, approximations to relativistic field theories. Treating the interaction field as a dynamical degree of freedom, we derive the thermodynamical potential in terms of fully dressed propagators, an approach which allows us to resolve the entropy of a relativistic plasma into contributions from its interacting elementary excitations. We illustrate the derivation for a hot QED plasma of massless particles. We also discuss how the self-consistency of the treatment manifests itself into relationships between the contributions from interaction and matter fields. [less ▲]

Les auteurs envisagent plus précisément les questions suivantes : accède-t-on à un emploi plus tard, à un âge plus avancé ? La prime-insertion est-elle précédée d'un délai d'attente plus important ? Ou par une période de chômage ? Y a-t-il des différences entre les parcours masculins et féminins ?

The results of the vertical profile retrievals are compared to the Halogen Occultation Experiment (HALOE) profiles, to the Cryogenic Infrared Spectrometers and Telescope (CRISTA2) second mission (August 1997) profiles for HNO3 and O3 and also to nearby ozone sondes and lidar profile for O3.

During 47 days, 80 weaned pigs, allotted to 2 groups of 30 and 50 animals, were given choice simultaneously between pellets or meal distributed ad libitum in feeders equipped with an integrated watering system. The average daily weight gain was 0.4250.058 kg, without significant difference between groups, and the mean feed conversion ratio was 1.72. The mean feed intake with pellets was double that with meal (0.49 vs. 0.24 kg/head daily). However, the pellet feeders and meal feeders were occupied for the same proportion of time: the mean occupation times were 45.5 and 42.8% (30 pigs) and 62.4 and 67.3% (50 pigs), respectively. Eating pellets seems thus to take less time than eating meal. Furthermore, we have observed that animals from the larger group were eating more quickly than members of the smaller one. Even if the feed intake of pigs with pellets was twice that with meal, pigs drank more water (60% of the total water intake) using the meal feeder. Thus, with pellets, pigs don't seem to choose a close association between feed and water consumption. In conclusion, pigs prefer pellets to meal, this choice being probably partially explained by a faster ingestion. This eating speed depending also on the group size, the number of eating places should thus take into account these two parameters. [less ▲]

In 1995 Christenfeld and Hill published a paper that purported to show at one year of age, infants resemble their fathers more than their mothers. Evolution, they argued, would have produced this result since it would ensure male parental resources, since the paternity of the infant would no longer be in doubt. We believe this result is false. We present the results of two experiments (and mention a third) which are very far from replicating Christenfeld and Hill's data. In addition, we provide an evolutionary explanation as to why evolution would not have favored the result reported by Christenfeld and Hill. [less ▲]

Long-term monitoring activities of some 20 atmospheric constituents are continuing at the International Scientific Station of the Jungfraujoch, Switzerland, based on remote infra-red solar observations with high spectral resolution Fourier transform spectrometers. As a contribution to non-CO2 greenhouse gas investigations, we report the trends observed in the vertical column abundances measured regularly since the mid-1980s for CH4, N2O, CO, CCl2F2, CHClF2 and SF6. With the exception of CO, all species show positive rates of change in their near past atmospheric loading, those of CH4, N2O and CCl2F2 having slowed significantly during the more recent years. The derived rates of change will be compared to findings resulting from ground-level in situ investigations at latitudes similar to that of the Jungfraujoch, and be interpreted in terms of resulting global loading changes.

A new mathematical approach is proposed to model the injection of a tracer in a well for field tracer tests. It is based on the water and tracer mass budget integrated over the injection well, for the different injection steps (tracer injection, water flush and tracer behaviour after the injection). This physical approach deals with well-bore mixing and dilution effects, local distortion of the flow field around the injection well, back-diffusion of the tracer in the injection well after the injection, and tracer capture in the well bore. A numerical solution (finite differences over time) is proposed and implemented in a three-dimensional finite element flow and transport simulator (SUFT3D). A radially converging tracer test is computed to illustrate the adequacy and usefulness of this new mathematical concept to model field results. [less ▲]

Observations of globular clusters show that they contain much too little gas or dust, compared to what should be present due to the mass-losing stars in the cluster. Many authors have been intrigued by the fate of the gas in globular clusters. They have suggested various mechanisms by which the gas could escape from the cluster, such as stellar UV radiation, cluster winds driven by X-ray bursters, novae, or flare-stars, relativistic winds from millisecond pulsars, condensation into stars, accretion processes drawing upon a central gas reservoir, continuous sweeping of the cluster gas by the gaseous medium of the Galactic halo dots. Recent results also show that globular cluster stars show many abundance anomalies. Accretion of interstellar gas by the cluster stars has been suggested as a plausible mechanism to explain these anomalies. It is also a major ingredient of the EASE scenario linking halo field stars to globular clusters, which we have recently developed to explain strong r-and s-elements correlations in halo field dwarf stars. Here we will briefly review the status of gas and dust detection in globular clusters, as well as the possible gas removal mechanisms. We will explore in more details the gas and dust accretion processes onto main sequence stars. In particular, we will study the efficiency of this mechanism in removing gas from the globular clusters interstellar medium. [less ▲]
