Knowledge of local soil strength variation may permit variation of tillage parameters to produce a more optimal soil structure for root growth and plant development. Soil strength mapping can provide another layer of information in precision agriculture. The aim of this research is to develop a sensor able to measure on-line the local soil strength variations. This sensor is designed as follows: a thin blade penetrates the soil to a specific depth while the machine is moving, a beam transfers the soil-blade forces to a transducer fixed on the machine. The transducer measures then the horizontal and vertical forces and the moment. This paper describes a field experiment performed in a 2 ha field of silt soil (Hesbaye, Belgium). The first objective of this research is to establish a map of soil strength variability of the field. For this purpose, the sensor is pulled through the soil in parallel traverses at 5 m separation by a tractor equiped with a DGPS receiver. The second objective of the experiment is to study relation between measured forces and several measured soil physical parameters. Ten homogeneous plots where identified on the sensor track in order to cover as completely as possible the diversity of soil physical conditions encountered. On the median line of each of those plots, 10 Cone Index penetrometry profiles were measured with a mobile automated penetrometer recorder, soil water content was measured in 5 points, ans soil samples were taken in the center of the plot to determine the following parameters: cohesion and internal friction angle, simple compression resistance, Atterberg's limits, granulometry and pF curves. This experiment allowed the first identification of different soil strength areas in the field investigated. [less ▲]

This paper presents apple grading into four classes according to European standards. Two varieties were tested, the Golden delicious and the Jonagold. The image database included more than thousand images of fruits (528 Golden, 642 Jonagold) belonging to three categories Extra, I, II and to reject. The image grading was achieved in six steps : the image acquisition, the ground colour classification, the defect segmentation, the calyx and stem recognition, the defects characterisation and finally the fruit classification in quality classes. The proposed method for apple external quality grading showed correct classification rates of 78 and 72% respectively for Golden delicious and for Jonagold apples. Taking into account that the healthy fruits were far better graded and considering that this class was under represented, the results of the proposed method (an error rate reaching respectively 5 and 10%) are compatible with the requirements of the European standards.

We present a holographic camera based on a photorefractive crystal. A first prototype instrument has been studied and built on the basis of a broad optimization study. Some applications in high accuracy displacement/deformation metrology are presented. This first instrument generation was not completely portable and flexible of use. For that reason, a compact device has been designed and is presented. New applications of this holographic camera are shown. All theses achievements show the versatility and flexibility of utilization, as well as the high degree of user-friendliness, of a photorefractive crystal based holographic camera. Future prospects are then discussed [less ▲]

A smart heating controller has a twofold objective: to save as much energy as possible while maintaining an acceptable comfort level in the building. Due to very large time constants in the building response, it has to anticipate internal and external disturbances. In the case of a passive solar commercial building, the need for anticipation is reinforced by important solar and internal gains. Indeed, large solar gains increase the energy savings potential but also the overheating risk. Optimal control theory presents an ideal formalism to solve this problem : its principle is to anticipate the building behaviour using a model and a forecasting of the disturbances in order to compute the control sequence that minimises a given cost function over the optimisation horizon. This cost function can combine comfort level and energy consumption. This paper presents the application of optimal control to auxiliary heating of a passive solar commercial building. Simulation-based and experimental results show that it can lead to significant energy savings while maintaining or improving the comfort level in this type of building. [less ▲]

We explore the dynamics of Saturn's F ring by following the orbital histories of circumplanetary particles between the orbits of Prometheus and Pandora. Our goal is to find structures that could be related to the F ring. Using a 3-D mapping integrator developped by Sicardy and Foryta (1996), we follow the behavior of several thousand test particles distributed unformly between 140,000 and 140,400 km in order to acquire a general picture of the dynamics of this zone. The model includes the gravitational effects of Saturn (up to J[SUB]4[/SUB]) and the two shepherd satellites. The numerical simulations show chaotic behaviors of the particles resulting in a close encounter with one or the other of the satellites, which deplete the zone between the satellites. The timescale over which particles are removed by the satellites is of order a ten thousand years. After a hundred thousand years, some particles exist but they are not related to the actual four strands of the F ring. As suggested by Cuzzi and Burns (1988), these simulations indicate that this ring may be a transient event occuring at the edge of the Roche limit. However, taking into account dissipation (collisions, viscosity) might help to explain the longevity and the location of this ring. This work was performed while the author held a National Research Council - NASA ARC Research Associateship. [less ▲]

La problématique de l’évaluation des compétences transversales est au centre des préoccupations actuelles. Alors que de nombreuses méthodes d’évaluation des compétences disciplinaires existent et sont usitées par les enseignants (interrogations au moyen de questions ouvertes, de QCM, examens oraux, …, Leclercq (1999), de Landsheere (1992)), l’évaluation des compétences transversales pose davantage de problèmes car, d’une part, la collecte d’informations permettant de juger de l’acquisition de ces compétences chez les élèves est plus délicate (elle nécessite souvent l’observation des élèves au cours de l’activité d’apprentissage, et ce au moyen de grilles d’observation (Denis, 1990)) ; d’autre part, l’acquisition des compétences transversales doit être envisagée à long terme et, par conséquent, leur évaluation doit se faire de manière continue et progressive. Une enquête réalisée auprès de 98 professeurs du cours d’Education par la Technologie1 révèle que 43% d’entre eux disent éprouver des difficultés pour apprécier l’acquisition de ces compétences chez leurs élèves (Hubert, Pauwen & Denis, 1997). De juillet 1997 à juin 1998, le Service de Technologie de l’Education de l’Université de Liège a été chargé par le Ministère de la Communauté française de mettre au point des outils permettant l’évaluation de ce type de compétences (Hubert, Bosmans & Denis, 1998). Cette recherche avait pour objectif de fournir aux enseignants du cours d’Education par la Technologie (ET) des méthodes et des moyens didactiques diversifiés pour évaluer les compétences transversales de leurs élèves lors d’activités de résolution de problèmes, mais aussi d’imaginer un système intégrant ces outils. Actuellement, l’évaluation de ces compétences fait également l’objet d’une réflexion dans le contexte de l’utilisation pédagogique d’Internet où les élèves sont amenés à réaliser, en groupe, un projet au moyen des potentialités offertes par Internet (Hubert, Detroz, Demily & Denis, 1999). Nous allons détailler, ici, les principes de base, les composantes principales et les modalités du système d’évaluation construit dans le cadre du cours d’ET. Nous tenterons d’attirer l’attention du lecteur sur les aspects méthodologiques qu’il convient d’annoncer à l’enseignant (et aux élèves). [less ▲]

La résistance mécanique d'un sol est un paramètre important qui conditionne la croissance racinaire et le développement des plantes. L'objectif de cette recherche est de mettre au point un capteur capable de mesurer en ligne les variations locales de résistance du sol. Celui-ci est constitué d'un anneau dynamométrique qui enregistre automatiquement les sollicitations (forces horizontales, verticales et couple) générées par la traction uniforme d'un lame dans le sol. Une première expérience a été menée dans un champ limoneux situé en Hesbaye (Belgique).

Furthermore, it is a sensitive method to early diagnosis of inflammatory process. It is also an unique tool to study the deposition of therapeutic aerosol within the respiratory tract. [less ▲]

This paper proposes a methodology for the design of automatic load shedding against long-term voltage instability. In a first step, a set of training scenarios is set up, corresponding to various operating conditions and disturbances. Each scenario is analyzed to determine the minimal load shedding which stabilizes the system, with due consideration for the shedding location and delay. In a second step, the parameters of a closed-loop undervoltage load shedding scheme are determined so as to: (i) approach as closely as possible the optimal sheddings computed in the first step, over the whole set of scenarios; (ii) stabilize the system in all the unstable scenarios and (iii) shed no load in the stable ones. The corresponding optimization problem is solved using a (micro-)Genetic Algorithm. A detailed example is given on the Hydro-Quebec system in which load shedding is presently planned. [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 ▲]

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 ▲]

En el marco de un proyecto de investigación mayor, dedicado a estudiar el impacto de la literatura traducida en el sistema literario argentino durante las décadas del cuarenta y del cincuenta, este trabajo pretende caracterizar el momento fundacional de dos emprendimientos editoriales para los cuales la traducción constituyó una práctica central: las editoriales Sur y Losada. Fundadas en 1933 y 1938 respectivamente, Sur y Losada promovieron las primeras traducciones al castellano de numerosas obras que luego se difundirían por el resto de América Latina. En el análisis se aborda tanto la selección de textos traducidos como las marcas textuales y paratextuales indicadoras del proceso de profesionalización del traductor. La hipótesis que se sostiene es que, si bien en décadas anteriores ya se había traducido literatura extranjera en Buenos Aires, será en la década del treinta cuando esta práctica discursiva alcanzara un estatuto que posibilita la plena identificación del traductor como enunciador segundo del texto literario extranjero.

A hydrodynamical model of the general circulation in the Black Sea has been build up, using the GHER (GeoHydrodynamics and Environment Research) three-dimensional, non-linear, baroclinic, turbulent closure model. A model with 5 km horizontal resolution and 25 vertical levels is used to compute the typical seasonal cycle by forcing the model with climatological monthly mean fields of temperature, salinity and wind stress at the air-sea interface. Furthermore, the river discharges of the Danube, the Dnestr and the Dnepr are taken into account. This high resolulion model resolves the baroclinic instabilities generated by the interactions of the boundary current with the coastline geometry or with the continental shelf/slope topography. A simple ecosystem model defined by a nitrogen cycle is coupled with Ihe hydrodynamical model. The state variables of this model are defined as those which are necessary and sufficient to assess the effects of the physical processes, and in particular of the boundary current instability , on the space time distribution of the primary and secondary productions. The results of the 3D ecohydrodynamic model are compared with CZCS data of surface chlorophyll fields collected during the period from 1978 to 1986. [less ▲]

Modelling human conditioning reasoning of the type 'if p then q' containing negations poses a challenge for connectionism. A network of spiking neurons (INFERNET) was used to model this type of conditional reasoning. This model also provides insights on certain human limitations. The model is compared to empirical data, and classical explanations. Statistical analysis shows that the model's performance not only surpasses classical explanations but also provides a very good overall fit to empirical data. INFERNET simulator results also compared to human performance. The simulations compare well with both human performance and limitations. [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 ▲]

The basic equations, the limitations and the main features of the parametric fire proposed in Annexe B of Eurocode 1 are given. 48 experimental fire tests are used to assess the validity of this model. The model has been applied to these tests and the comparison has been made, for each test, on the maximum temperature in the air and on the maximum temperature calculated in 2 hypothetical steel sections, one thermally protected and one unprotected. The agreement is very poor for the air and for the unprotected steel temperature, and somewhat better for the protected steel temperature. Some proposals are made which allow to improve the agreement, while keeping the same expressions for the parametric fire. These modifications concern the equivalent thermal properties of multi material walls, and the introduction of a minimum duration of the fire and a of a ventilation effect in case of fuel-bed controlled fires.

We review the current status of our long-term monitoring project on slowly pulsating B stars that we started in the course of 1996 and that was recently completed as far as the first part of our plan is concerned. In total, we have selected 17 southern and 8 northern stars. The idea is to fully exploit our current data in the near future and to select the most interesting targets for further very-long-term follow-up monitoring. A first conclusion is that half of the southern targets turn out to be spectroscopic binaries. Some of these have circular orbits and periods of the same order of magnitude as the intrinsic pulsation period(s) of the primary. The eccentric binaries have periods ranging from 12 to 460 d. For most stars the photometric behaviour is dominated by the same frequency as the intrinsic spectroscopic variability. Multiperiodicity in the expected frequency range is found for almost all stars. Two objects, however, turn out to have only one dominant pulsation mode. [less ▲]

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 ▲]

The application of the GHER 3D primitive equation model to the simulation of the seasonal cycle of the Mediterranean and Black Sea circulation will be shown. The two basins are very illustrative for either concentration or dilution basins, and modelling such different systems needs some special attention with respect to the representation of the water masses and mixing between the different layers. The strength of the variability of both basins will be compared, including comparison with climatological data. Turbulent characteristics in both cases alalysed, showing that at the scales under investigations, both turbulent regimes are close to a balance between production, destruction and vertical diffusion of turbulence. ft is also shown how the river dominaled Black Sea exhibits specific free surface behaviors while the Mediterranean Sea exhibits specific deep water formations leading both to a different kind of vertical mixing.

An array of tin-oxide sensors is used to continuously monitor different odour emissions in the environment. The paper presents some issues aiming at improving the portability and the user-friendliness of the instrument as well as testing what kind of signal may be used to monitor the odour "intensity". Main results are the following. The test of various pre-processing data algorithms pointed out that the use of pure reference air could be avoided, as long as the sensors are allowed to periodically regenerate in the presence of ambient air. Sensor array in static contact with ambient air could be sufficient for the on-line monitoring, but the use of a controlled gas flow system to transfer the odour from the source is better to avoid the influence of air movement on the heated sensors. The control of the temperature and the humidity of the gas and the thermo-regulation of the sensor chamber don't seem essential, even for outdoor operation. When trying to build a regression model linking the odour intensity to the sensor signals, Partial Least Square (PLS) model gives better results with respect to Multi Linear Regression or Principal Component regression models. For an application around a landfill area, where sensor signals are compared to the personal feeling of the operator in the field, PLS gives a percentage of 71% correct intensity prediction.

During summer, channelized sectors of the Mosel and Saar rivers undergo severe oxygen depletion episodes that compromise their ecological value. A programme was launched by the International Commission for the Protection of river Mosel and Saar (ICPMS) in order to identify the causes of this situation. All processes involved in the oxygen budget, including photosynthesis, algal, bacterial, zooplanktonic, zoobenthic respiration and nitrification, were investigated, and oxygen budgets for different seasonal situations were established. In close connection with these field investigations, three different mathematical models of the ecological functioning of the river system were implemented: the BfG model of the Saar and Mosel Rivers , the ULg Meuse model, adapted to the river Mosel, and the Mosarel model, resulting from the application to the Mosel-Saar river system of the RIVERSTRAHLER modelling approach We here describe the common features and differences in the conception of these models and present a few examples of their results.

Based on the experimental results, earlier work presented a first attempt at the statistical modelling of the friction and wear valves and seals of rocket engines must withstand. Available friction coefficients and wear rates (as defined in Archard’s equation) were fitted against two independent variables : sliding speed and contact pressure. The computations yielded second-degree polynomials and the corresponding response surfaces. However, it was felt that a statistical design of experiments to reduce the test activities and maximise result quality was needed. A detailed analysis led to the choice of Doehlert’s approach, with a contribution of the general equiradial design. Testing was performed with a pin-on-disk tribometer capable of working at room temperature (RT) and under liquid nitrogen (at 77 K). The results pertaining to two examples are discussed. Statistical as well as practical aspects of the work performed and consequences of the results are covered : based on correlation factors and other mathematical indicators, on the general profile of the response surfaces and on requirements for use, the tribological properties of the considered materials are illustrated, leading to their eventual usefulness in cryotechnic equipment and space applications.

In the Walloon region (southern Belgium), the forests of indigenous oaks (Quercus robur and Quercus petraea) cover about 80 000 ha (17% of the total forest surface ). They represent more than 39% of the standing hardwoods, with 14 million m3. As in neighbouring countries, they showed serious decline symptoms in the early 80s. The investigations conducted since that time didn't point out any single cause to the phenomenon. Far from observing a stabilization of the phenomenon, a recent outbreak occurred in 1998 and 1999. Locally, the number of dead trees reached values such as 20 to 25 individuals per hectare in mature forests. On the basis of sampling (82 plots, more than 2000 trees) covering all natural areas which are supposed to be favourable to both oak species, the study noted similar distribution of the trees in defoliation classes for Quercus petraea as well as Quercus robur .
