Whether the memory for temporal context information is mediated by automatic or controlled processes is a matter of debate. If the coding of temporal context information is automatic, memory for temporal context should not be affected by intention to learn and aging. In order to address this issue, we administered a list discrimination task to young and older adults in either an incidental or an intentional encoding condition. The results showed that the list discrimination performance of the older adults was inferior to the performance of the young subjects. In addition, both young and older subjects’ discrimination performance did not improve in the intentional encoding condition. These results support the hypotheses that the temporal context of an item is encoded automatically. [less ▲]

An elastic-viscous-plastic constitutive law (Norton-Hoff type) is coupled to a contact law in a finite element code in order to model the behaviour of a steel strand in the mould of a continuous casting machine. Both thermal and mechanical type fields are computed. The objective is to compare for different industrial process conditions the thickness of the solidified shell as well as the stress and strain levels in this layer. More particularly, the model should lead to optimise the taper of the mould for different cross sections of steel strand. [less ▲]

A three-dimensional coupled biogeochemical-hydrodynamical model has been developed to get a better understanding of the biogeochemical functioning of the Black Sea. The in?uence on the ecodynamics of hydrodynamical and biogeochemical processes is quantified. Nitrogen inputs from the rivers, from the sediments and from the deep sea are estimated and compared in terms of potential fertilization. The exchanges between the north-western shelf and the deep sea are quantified. The results illustrate a highly complex spatial variability of the phytoplankton annual cycle and thus, stress the importance of using a 3D model to capture the essential physical-biological interactions that explain the data.

It has been hypothesised that the hippocampal regions are involved specifically in the encoding of associations between different kinds of information and in the recollection process of recognition memory. We examined the performance of two severely amnesic patients (AC and MR) with different kinds of lesions on three associative (one intra-modal and two inter-modal) recognition tasks and two item recognition tasks. AC was impaired on all the tasks, whereas MR was impaired on the associative tasks but had a preserved familiarity-based recognition. Combined with the etiology and the loci of the patients’ lesions, these results support partly the hypothesis. [less ▲]

Nowadays, turbine engine tests are processed using an open loop, i.e. the measurements are verified and treated a posteriori, sometimes weeks or months after the end of the test. The purpose of the present project is to develop a new methodology which enables real time detection of faulty measurements and the suppression of the source of these faults during the test. The validation of the measurements is achieved by a “robust” parameter identification [1]. Such a method is called robust in the sense that it can cope with 20 to 30% of faulty measurements. The robustness is insured by a distribution of the measurement noise, as introduced by Huber [7, 8], that takes into account the possibility of faults. The purpose of a parameter identification is to find the set of parameters which has most likely generated the measurements observed on the process. This leads to an optimisation problem that has to be solved for the parameters. The measurements are linked to the parameters through a non-linear model, leading to a large system of equations for modern jet engines. If no physical model of the process can be made available or if this model is too complex to allow real time validation, automatic learning methods may provide a solution: • either a mathematical representation is generated, directly based on the measurements (online learning), • or a database is first generated, based on the existing (but expensive) physical model, the database being subsequently used to build a statistical model (off-line learning). Neural networks seem to be very suitable for modeling the behavior of turbojets, avoiding the resolution of a time-consuming non-linear system. In this paper neural networks are tested to generate a mathematical representation of a single flow, single spool and variable geometry nozzle turbojet, from a data base of “measurements” generated by a physical model of the engine. Only the off-line learning approach is considered. [less ▲]

The brain must be capable of achieving extraordinarily precise sub-milisecond timing with imprecise neural hardware. We discuss how this might be possible using synfire chains (Abeles, 1991) and present a synfire chain learning algorithm for a sparsely-distributed network of spiking neurons (Sougné, 1999). Surprisingly, we show that this learning is not subject to catastrophic interference, a problem that plagues many standard connectionist networks. We show that the forgetting of synfire chains in this type of network closely resembles the classing forgetting pattern described by Barnes [less ▲]

A three-step model of coaches’ tactical thinking process is proposed: pre-interactive, interactive and post-interactive decisions. This study focuses on the interactive decisions. Its first objective was to verify if a coach is able to report these decisions at the end of a game. The second objective was to analyse the goals and factors inducing the decisions. Data were collected during and after four games directed by two coaches, one in basketball, and the other in volleyball. Their teams participated in the second division of the Belgian national championship (1998-1999). The research method was similar to that developed by Gilbert, Trudel, and Haughian (1999). Coaches reported a limited number (1 to 9) of tactical decisions immediately after each game. Decisions reported by the coaches and additional decisions selected by researchers from videotapes of the games were used for stimulated recall interviews. A total of 82 decisions were analysed with the basketball coach and 88 with the volleyball coach. Data analysis was considered separately for each coach. Calling time out, player substitutions, and tactical cues were the most frequently analysed decisions. Adapting the team strategy and providing information or directives were the priority goals of the decisions. Most of the decisions were determined by subjective field information. [less ▲]

A long-term survey of the P. oceanica meadow has been in progress since 1975 in the Revallata Bay (Corsica, France) (e.g.Bay, 1984). Actually, since 1991, biometric parameters of the meadow have been monitored regularly (Gobert et al., 1995). The seasonal, interannual and long term changes of these Posidonia characteristics are analysed regarding meteorological (e.g.sun, rain, temperature..)and anthropologic events such as tourism and nutrient enriched effluents in the area. Our results have pointed out the good health status of the meadow in spite of some ecological modifications linked to the increasing water temperature (Gobert et al., in press). Recent aerial photos have shown a modification of the covering surface of the meadow. An accurate studyof causes of the distribution modifications is beginning. Using our long term background data on the meadow, we are developing a transplantation technique of P. oceanica shoots using semi-artificial substrates (EAT:electrochemical accretion technology) (Van Treeck and Schuhmacher, 1998) with the aim of providing a guideline-report based on model case studies representative for many threatened Mediterranean areas.

For long applications and for many others, a material with properties between hard metal and high speed steel is necessary. This material should have a high resistance to wear together with good toughness.

In varying the nature and the proportions of reinforcement and matrix, the properties of the composite can cover many applications. [less ▲]

In this paper, a dual perturb and combine algorithm is proposed which consists in producing the perturbed predictions at the prediction stage using only one model. To this end, the attribute vector of a test case is perturbed several times by an additive random noise, the model is applied to each of these perturbed vectors and the resulting predictions are aggregated. An analytical version of this algorithm is described in the context of decision tree induction. From experiments on several datasets, it appears that this simple algorithm yields significant improvements on several problems, sometimes comparable to those obtained with bagging. When combined with decision tree bagging, this algorithm also improves accuracy in many problems. [less ▲]

The restoring force surface method offers an efficient and reliable identification of non-linear single-degree-of-freedom systems. The method may be extended to multidegree-of-freedom systems but by loosing the key advantage of the method which lies in the two-dimensional representation for single-degree-of-freedom systems. An experimental application of the restoring force surface method is considered in the present paper. The structure investigated consists of wire rope isolators mounted between a load mass and a base mass. These helical isolators were found to be characterised by a non-linear behaviour. The results obtained are discussed in details and the advantages and drawbacks of the method are underlined. [less ▲]

An approach to modal analysis and modal identification is proposed, capable of complementing the panoply of existing methods. It is based on a hybrid time-domain – direct transient stability method called SIME (for SIngle Machine Equivalent). In short, SIME uses a conventional transient stability program to transform the time varying parameters of the system into those of a one-machine infinite bus (OMIB) equivalent system. The representations of this OMIB allow substantial reduction of the original problem’s dimensionality. Many important advantages may result. For example, the multimachine system unstable equilibrium point (UEP) can readily be derived from the OMIB UEP, which is calculated analytically and unambiguously in a two-dimensional space. Further, the interplay between multimachine and OMIB characteristics and their complementary properties provides a better understanding and handling of damping, inter-area oscillations and their control. More generally, modal analysis and modal identification tasks get closer to each other and easier to handle. The paper essentially focuses on the approach as such rather than on potential applications. Simulations carried out on a 3-machine system illustrate main features. [less ▲]

After a brief introduction to nulling interferometry, we emphasize the limitations of this technique for the detection of exoplanets, and the need for internal modulation, a recent technique for fast signal chopping. The principles of internal modulation are then discussed and illustrated with an example. Our contribution to the Darwin mission deals with the study of new aperture configurations using internal modulation. the best two configurations identified among an infinity of new possibilities are presented. As compared to the current Darwin configuration, the sensitivity to the planetary signal is improved by a factor of two, resulting in a fourfold speedup in the detection and characterization of exoplanets.

The working principle of liquid mirror telescopes (LMTs) is first reviewed along with their advantages and disadvantages over classical telescopes. For several reasons (access to regions near the south galactic pole, galactic center, good image quality, etc.), an excellent site for such an LMT is the Atacama desert. A deep (B~24 mag) LMT survey at latitudes near -22deg -- -29deg will cover ~90 square degrees at high galactic latitude and be especially useful for gravitational lensing studies, for the identification of various classes of interesting extragalactic objects (cf. clusters, supernovae, etc. at high redshift) and for subsequent follow-up observations with 8 m-class telescopes. A short description of the handling of data products is also presented. [less ▲]

This paper presents the results of the investigation of the biological activity that takes place in four municipal solid waste landfills situated in different regions of two dry climate countries i.e. Haiti and Tunisia. Since the climatic water balance is negative (potential evapotranspiration being 1.5 to 5 times higher than rainfall), it has often been considered that this kind of landfill has neither environmental impact nor efficient biological activity. However, the four landfills revealed a biological activity with biogas often containing more than 60 percent of methane. Indeed, under the upper waste layer that was effectively dry (dry weight from 85 to 98 %), the core of refuse contained between 35 and 65 % of dry matter. In some boreholes, the produced gases periodically expelled leachates like small geysers. Therefore, the results assess that landfill management in countries with dry climate should be considered with adapted technologies, not necessary the same as under temperate or humid climates [less ▲]

This paper presents the results of a five-year experience in collecting data's on landfills and dumpsites in developing countries. At present time, information about 81 landfills from 12 countries has been collected. The main partners of this project are Tunisia, Haiti, Senegal and Burkina Faso. Besides those factual partnerships, new collaboration projects are being discussed with Guinea, Cuba, Vietnam and Kuwait. The data are gathered in the Atlas of MSW landfills and dumpsites in developing countries and are published on the Internet (http://www.ulg.ac.be/cwbi/index.htm). The purpose of such a project is to keep in memory the existence and characterisation of the main landfills and dumpsites in order to allow the identification and the management of their negative impacts on the environment. Moreover, it will be useful to set up proper rehabilitation projects. This work has already received the positive support of people involved in waste management in West Africa. [less ▲]
