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 unified approach to transient stability closed-loop control is presented. It relies on the general transient stability method called SIME, from which the Preventive and the Emergency SIMEs are derived. The Preventive SIME uses time-domain simulations of plausible contingencies prior to their occurrence, for the online power system monitoring from the control room. The Emergency SIME, on the other hand, uses real-time measurements, acquired on the system power plants after the actual occurrence of a contingency in order to appraise and trigger countermeasures indispensable for the system integrity. Despite fundamental differences in their design and objectives, the two approaches have also common features. This paper highlights main differences and similarities, and illustrates them on a realistic, large power system. The tradeoff between on-line preventive control and real-time emergency control is also assessed in terms of size of the involved countermeasures. [less ▲]

This presentation outlines the organisational background of the whole process and the rationale underlining the choice of the methodologies used to survey the health needs of the health care workers and to define priorities. In order to elicit effective participation from the staff members, several questions have to be addressed in the transitional phase between problem situations assessment and ergonomic intervention : which channels use to disseminate the information about the survey results, what role for the top rnanagernent of the hospital and for the ergonomic experts, which support methodologies should be provided for initiating the change process?

Several adaptive controllers which universally achieve the so-called lambda -tracking have been proposed in the literature. From a practical point of view, previous results are not usable for systems with a high relative degree because of bad numerical conditioning. The paper presents a modified approach overcoming this numerical problem while achieving the same robust stability properties. Stability and convergence of the adaptation is proven for tracking a large class of reference trajectories. The design of the controller is very simple and intuitive, only few parameters have to be tuned and little structural information about the system to be controlled is needed [less ▲]

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 ▲]

This paper investigates enhancements of decision tree bagging which mainly aims at improving computation times, but also accuracy. The three questions which are reconsidered are: discretization of continuous attributes, tree pruning, and sampling schemes. A very simple discretization procedure is proposed, resulting in a dramatic speedup without significant decrease in accuracy. Then a new method is proposed to prune an ensemble of trees in a combined fashion, which is significantly more effective than individual pruning. Finally, different resampling schemes are considered leading to different CPU time/accuracy tradeoffs. Combining all these enhancements makes it possible to apply tree bagging to very large datasets, with computational performances similar to single tree induction. Simulations are carried out on two synthetic databases and four real-life datasets. [less ▲]

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 ▲]

In this paper, a temporal machine learning method is presented which is able to automatically construct rules allowing to detect as soon as possible an event using past and present measurements made on a complex system. This method can take as inputs dynamic scenarios directly described by temporal variables and provides easily readable results in the form of detection trees. The application of this method is discussed in the context of switching control. Switching (or discrete event) control of continuous systems consists in changing the structure of a system in such a way as to contreol its behavior. Given a particular discrete control switch, detection trees are applied to the induction of rules which decide based on the available measurements whether or not to operate a switch. Two practical applications are discussed in the context of electrical power systems emergency control. [less ▲]

Variable step strategies are specially well suited to deal with problems characterized by high non-linearity and contact/impact. Both phenomena are typical of dynamic simulations of the interactions between a turbine blade and its casing, the most dramatic example being blade loss. Constant step size strategies do not give satisfactory answer for this kind of problems, since it is very difficult, if not impossible, for the user to find an appropriate time step that does not lead to divergence nor generate extremely costly computations. An automatic time stepping algorithm is proposed, which takes into account the recent history of accelerations in the bodies under consideration. More precisely, the adaptation algorithm is based on estimators of the integration error of the differential dynamic balance equations. This allows for adaptation of the time step to capture correctly the transient phenomena, with characteristic times which can range from relatively long (in regime) to very short (blade loss), thus ensuring precision while keeping the computation cost to a minimum. Additionally, the proposed algorithm automatically takes decisions regarding the necessity of updating the tangent matrix or stopping the iterations, further reducing the computational cost. As an illustration of the capabilities of this algorithm, several numerical simulations of both academic and industrial (the contact/impact between a turbine blade and the casing) problems will be presented.

An automatic time step size determination for non-linear problems, solved by implicit schemes, is presented. The time step calculation is based on the estimation of the integration error. This estimation is calculated from the acceleration difference. It is normalised according to the size of the problem and the integration parameters. This time step control algorithm modifies the time step size only if the problem has a long time physical change. On the other hand, Hessian matrix can be kept constant for several iterations however the problem is non-linear. According to the fact that the time step size is constant for some time step, the Hessian matrix shouldn’t be recalculated for each time step. A criterion selecting if Hessian matrix must be calculated or not is developed. Finally, a criterion of iterations divergence is also proposed. It avoids the determination, by the user, of a maximal iterations number. The iterations number is the smaller. Industrial numerical examples are presented that demonstrated the performances (precision and computational cost) of the algorithms. [less ▲]

Swaged bolts are an alternative to high strength (HS) bolts for connections in steel structures. To clarify the different steps involved during their specific installation process, a numerical modelling has been carried out. It allows the relevant phenomena to be described and to be evaluated. This numerical calculation accounts for mechanical plasticity and friction contact between the components of swaged bolts. The finite element code "Lagamine" designed for the forming analysis that requires the modelling of the friction between plastically deformable solids has been used with an original and quite efficient way to take into account the contact. The drawing of the stress distributions during and after the swaging process is the main result of this research. [less ▲]

The dissociative photoionization of C2H3Br+ in the Br and HBr loss channels is reported. The KER distributions are analyzed by the Maximum Entropy Method (MEM). It can be concluded that at low and high internal energy the dissociations are statistical. At intermediate internal energies the excess energy is not completely randomized. [less ▲]

A la fin des années 1960, afin de répondre aux besoins des autorités locales, l’Institut national de statistique (I.N.S.) a pris l’initiative de découper le territoire communal de toute la Belgique en une vingtaine de milliers de secteurs statistiques. En vue du recensement de 2001, l’I.N.S. a décidé d’actualiser les limites des secteurs. À cette fin, un projet pilote de deux ans a été conçu. Il a pour objectif la mise au point d’une filière de production permettant: 1) de repérer, sur des images satellitaires, les zones rurales présentant des noyaux d’habitat (utilisation des 59 images HRV de SPOT des couvertures 1995 et 1996 de la Belgique); 2) de réaliser l’actualisation des secteurs statistiques par photo-interprétation assistée par ordinateur (PIAO) à partir des orthophotoplans. La méthodologie retenue comprend notamment: 1) le découpage du projet en «zones» homogènes de travail; 2) la réalisation du masque du bâti par classification non dirigée; 3) la détection des noyaux de bâti; 4) l’élaboration de la liste des secteurs dont le découpage doit être vérifié; 5) la création des nouveaux secteurs statistiques d’habitat groupé par PIAO. 7 467 noyaux ont été détectés dans 3 673 secteurs candidats à l’actualisation. Ces secteurs sont généralement localisés à la périphérie des villes et correspondent souvent à de nouveaux lotissements ou à un accroissement au départ d’anciens noyaux d’habitat. À terme, le nouveau découpage permettra à l'I.N.S. de ventiler ses statistiques sur des unités territoriales épousant mieux les limites des agglomérations. [less ▲]

Surface and internal quality of continuous casts depends very much on the behaviour of the strand in the mould. Among the parameters likely to influence this behaviour, the mould taper takes a prominen tpart. In order to understand better the influence of this parameter, we build up a thermal-mechanical finite element model. A slice of the strand is modelled and its evolution is observed. The main results are temperature field and solidification evolution, stree, strain and strain rate fields and losses of contact and returns to contact analysis. The model includes an elastic-viscous-plastic law, to describe the behaviour of steel from liquid to solid state, a thermal-mechanical element that takes into account thermal expansion and mechanical behaviour of the strand, a unilateral contact element, z mobile rigid boundary element to model the mould and its taper and an adapted loading element to model the ferrostatic pressure according to the liquid or solid state. This paper presents the first results obtained with an relatively simple section ( a125 mm square billet). Now the model is used with more complex section (beam blanks) and its validation is going on. [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.

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 ▲]

Dans des sociétés en profonde mutation, accéder au marché de l'emploi et s'y maintenir est devenu plus complexe. De plus en plus de trajectoires professionnelles sont marquées par la discontinuité et la précarité. Ces constats sont tirés de l'analyse de données collectées dans le cadre d'une analyse par panel (PSBH). 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 ? Dans quelle mesure le type ou le niveau de la formation qui a précédé influencent-ils les modalités d'entrée sur le marché de l'emploi ? [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 ▲]
