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

ln small ruminants, the costs of embryo transfer is a main limiting factor to the use of this method. The use of ultra rapid techniques such as embryo vitrification and direct transfer may contribute to reduce a part of the costs and increase the use of embryo transfer in sheep and goats. ln order to evaluate the efficiency of these techniques, two experiments were performed. ln a first experiment the viability of vitrified/thawed embryos was compared to results obtained after transfer of fresh embryos in ewes or frozen embryos (with slow freezing method) in goats. The pregnancy raté at term as weIl as embryo survival rate did not differ significantly according to embryo treatment (in ewes : 72% and 60% for fresh embryos vs 72% and 50% for vitrified embryos; in goats : 69% and 55% for frozen embryos vs 48% and 39 % for vitrified embryos). ln a second experiment, the possibility to transfer the vitrified embryos or frozen embryos directly after thawing (without cryoprotectant removal and evaluation of the morphological status of the embryos) was tested by comparison with the standard technique of transfer of vitrified or frozen/thawed embryos (removal of cryoprotectant and morphological evaluation). No significant effect of the transfer method was observed on the pregnancy rate at term and embryo survival rate (in ewes/vitrified embryos : 67% and 49% for traditional transfer vs 75% and 53% for direct transfer ; in goats/ vitrified embryos : 23% and 15% for traditional transfer vs 38% and 26% for direct transfer ; in goats/frozen embryos : 74% and 45% for traditional transfer vs 71% and 57% for direct transfer) [less ▲]

Motivational aspects play a particularly important role in teaching. They are considered a powerful mediator between teacher action and teaching effects. Pupils’ motivation towards school and physical education has already been analysed from the pupils’ point of view (Piéron, Ledent, Almond, Airstone and Newsburry, 1996). On another side, its perception by teachers is less documented. This study focused on the identification by PE teachers of pupils’ behaviours indicating that they were motivated or not. Moreover, perception of reasons related to lack of motivation in pupils was also investigated. Twenty-nine teachers fulfilled a questionnaire during an inservice preparation seminar. Their answers were analysed and inductively classified in categories. Thirteen categories of criteria showing the presence or lack of motivation were identified. Motivation was predominantly perceived by (1) the quality of the working climate (16.8%); (2) the intend to be involved in the PE lesson (14%); (3) positive reactions towards the subject matter (11.2%) and an efficient time management (11.2%). The most important categories related to lack of motivation were: (1) absences or excuses (20.2%); (2) low time on task (14%) and (3) negative reactions towards the subject matter (14%). Concerning origins of the lack of motivation, teachers emphasised: (1) the large differences between pupils (13.7%); the lack of sport culture of youth (10.5%) and (3) the negative pupils’ attitude towards school.

The present work shows the procedure used to determine the nature of carbides, while using Scanning Electron Microscopy and Energy Dispersive Spectroscopy with X-rays. Then we lay emphasis on optical characterization of carbides. Optical characterization of carbides appear to be the preliminary stage for the general assessment of carbides in HSS microstructure, the final stage of the scheme being the correlation between microstructure parameters (carbides and matrix) and mechanical properties of HSS hot rolling mills rolls.

A 3-D, high resolution model is used to investigate the impact of the Calvi canyon on the ecohydrodynamics in early spring conditions. Numerical runs are performed to simulate the nitrate distribution. Results show that the canyon topography generates high downwelling (upwelling) in the western (eastern) part of the canyon. Downwelling is larger than upwelling within the canyon leading to a net downward nitrate transport there, while upstream and downstream of the canyon there are regions of upwelled water richer in nitrate. Simulations are performed for NE, upwelling favorable, wind conditions where data of nitrate concentration are available for model validation. [less ▲]

The University of Mining and Geology in Sofia as a unique academic Institution engaged in training graduates to work in the field of mining and geological prospecting faces the need for modification and updating its curriculum, for being able to meet the challenges of European educational standards like Institution accreditation, ECTS, etc. In a smaller scale, this is particularly relevant to the Department of Mineral Processing which is one of the largest Departments (in the University) and is engaged in training students for the entire raw materials (non-petroleum) industry: ores, coal and industrial minerals. Despite the drastic reduction in great number undergraduate specialisations, the specialization “Mineral Processing” remains in the Governmental Register released by the Ministry of Education, Science and Technologies. Therefore in this new situation, there is a necessity to verify and to parallel the existing syllabus to the one practiced in a similar Departments in the EU countries and more precisely to develop undergraduate and graduate courses to include risk and hazard assessment, environmental protection and related matters.

In the current steel constructions, the use of thin-walled members has become an everyday reality, through the use of welded profiles on one side and cold-formed profiles on the other side. This tendency leads the engineers, even for structural elements having a beam aspect, to account for a wide range of phenomena, neglected in the traditional steel constructions, and associated with the deformability of the cross sections of the used profiles. So phenomena such as local buckling, distortional buckling, lateral buckling of the flanges, or torsion resistance by distortion of the profile cannot be ignored anymore. In this perspective, the present paper presents some theoretical bases for the development of a special plane beam element allowing to account for the cross section deformability. The main idea consists in adding a complementary local displacement field, describing the cross section deformation, on a classical beam element, for which the section is assumed to be rigid. Some results are then presented, for both critical and non linear behaviour. [less ▲]

One goal of the COST 517 project entitled “Effects of inclusions and carbides on the mechanical properties of alloyed steels” is to establish quantitative and statistical relations between the microstructure and the mechanical properties of rolls materials. This paper presents the different steps necessary to characterise the microstructure and the carbides presents in high-speed steel rolls. First, carbides were examined by SEM and EDX microscopy. Then, images of samples were acquired by optical microscopy and analysed to finally measure quantitative parameters describing the grains and the carbides. [less ▲]

A common cause of errors in CCD differential photometry is an improper calibration of the array. The importance of these errors is evaluated for different cameras with fields between 3 and 30 arcminutes. The usual superflat illumination corrections based on night sky exposures are often found to be unsatisfactory. ``Photometric superflats'' based on stellar measurements are more reliable and should be used instead.

Image analysis is used to describe quantitatively various different natures of carbides in high speed steel rolls. After an etching judiciously selected, the identification and the extraction of the carbide types are based on spectral differences. For every carbide type, three parameters are measure : the size, the spatial distribution and the volume fraction. The size of martensite grain is also measured. [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 ▲]

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 ▲]

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 ▲]

This work presents an original method for testing the biological reactivity of cellulose. This test specifically targets one of the limiting steps of cellulose bioconversion into biogas, i.e. the cellulose hydrolysis. From this point of view, enzymes-mediated hydrolysis has been performed to evaluate cellulose bioavailability in refuse samples from different layers of an old landfill. The relationship between the cellulose enzymatic accessibility and the lignin contents has also been studied. Similarly, the correlation between cellulose, lignin and humic acid contents has been investigated. On the other hand, moisture content in landfills is considered as one of the most important factors that favours methanogenesis. In this respect, the influence of moisture content on cellulose enzymatic hydrolysis has also been evaluated. [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 ▲]

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 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 ▲]

The measure of annoyance odours from sewage treatment, landfill and agricultural practise has become highly significant in the control and prevention of odorous emissions from existing facilities and is crucial for new planning applications. Current methods (such as GC-MS analysis, H2S and NH3 measurements) provide an accurate description of chemical compositions or act as surrogates for odour strength, but tell us very little about the perceived effect, whereas olfactometry gives the right human response but is very subjectivity and expensive. The use of non-specific sensor arrays may offer an objective and on-line instrument for assessing olfactive annoyance. Results have shown that sensor array systems can discriminate between different odour sources (wastewater, livestock and landfill). The response patterns from these sources can be significantly different and that the intensity of sensor responses is proportional to the concentration of the volatiles. The correlation of the sensors responses against odour strenghts have also shown that reasonable fits can be obtained for a range of odour concentrations (100 - 800.000 ou m3). However, the influence of environmental fluctuations (humidity and temperature) on sensor baselines still remains an obstacle, as well as the need for periodic calibration of the sensory system and the choice of a suitable gas for different environmental odours.

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 ▲]
