An enterprise network is analyzed from the viewpoint of an end-product manufacturer who receives customer orders and organises his production and supply policy so as to minimize the sum of his average holding cost and average stock-out cost. For each main component to be ordered, the producer has several possible suppliers. The arrivals of customers’ orders are random and delivery times from suppliers are also supposed random. This supply system is represented as a queuing network and the producer uses a base-stock inventory control policy that keeps constant the position inventory level (current inventory level + pending replenishment orders). The decision variables are the reference position inventory level and the percentages of orders sent to the different suppliers. In the queuing network model, the percentages of orders are implemented as Bernoulli branching parameters. A close-form expression of the expected cost criterion is obtained as a complex non-linear function of decision variables. A decomposed approach is proposed for solving the optimization problem in an approximate manner. The quality of the approximate solution is evaluated by comparison to the exact solution, which can be computed numerically in some simple cases, in particular in the two-supplier case. Numerical applications show the important economic advantage for the producer of sending orders to several suppliers rather than to a single one. [less ▲]

The Solar Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory will characterize the dynamical evolution of the solar plasma from the chromosphere to the corona, and will follow the connection of plasma dynamics with magnetic activity throughout the solar atmosphere. The AIA consists of 7 high-resolution imaging telescopes in the following spectral bandpasses: 1215Å. Ly-a, 304 Å He II, 629 Å OV, 465 Å Ne VII, 195 Å Fe XII (includes Fe XXIV), 284 Å Fe XV, and 335 Å Fe XVI. The telescopes are grouped by instrumental approach: the MAGRITTE Filtergraphs (R. MAGRITTE, famous 20th Century Belgian Surrealistic Artist), five multilayer EUV channels with bandpasses ranging from 195 to 1216 Å, and the SPECTRE Spectroheliograph with one soft-EUV channel at OV 629 Å. They will be simultaneously operated with a 10-second imaging cadence. These two instruments, the electronic boxes and two redundant Guide Telescopes (GT) constitute the AIA suite. They will be mounted and coaligned on a dedicated common optical bench. The GTs will provide pointing jitter information to the whole SHARPP assembly. This paper presents the selected technologies, the different challenges, the trade-offs to be made in phase A, and the model philosophy. From a scientific viewpoint, the unique combination high temporal and spatial resolutions with the simultaneous multi-channel capability will allow MAGRITTE / SPECTRE to explore new domains in the dynamics of the solar atmosphere, in particular the fast small-scale phenomena. We show how the spectral channels of the different instruments were derived to fulfill the AIA scientific objectives, and we outline how this imager array will address key science issues, like the transition region and coronal waves or flare precursors, in coordination with other SDO experiments. We finally describe the real-time solar monitoring products that will be made available for space-weather forecasting applications. [less ▲]

Predicting terminals movements in mobile networks is useful for more than one reason, in particular for routing management. A way to do such prediction is to learn the movement patterns of mobile nodes passing by an access router. In this paper, the information (e.g. layer 2 measurements) related to the different paths followed by mobiles are learned using a hidden Markov model. Simulations have been done using this method and show it can handle different layer~2 signals and collect statistical information when no such signal is available. Furthermore, the method works when no information is available and can be extended so as to guess the timing of the handoffs. [less ▲]

At the microscale, classical bearings such as ball bearings, sliding bearings and other pivots may be difficult to manufacture. Among all possible solutions to replace them, the notch hing seems to be very attractive through its many advantages. The major limitation is on the rotation angle. This paper presents a new simplified analytical model for the prediction of the maximum angular displacement and the angular stiffness of a notch hinge. To validate our model, an experimental set-up has been developed. [less ▲]

L’objectif des études synthétisées dans cette communication consiste à mettre au point une méthode in vitro, simple, fiable et respectueuse du bien-être animal, pour mesurer la fermentation des fibres dans le gros intestin du porc. Les travaux ont été réalisés en adaptant la méthode de BOISEN et FERNANDEZ à la pepsine-pancréatine pour simuler la digestion des aliments dans la première partie du tube digestif. La méthode d’incubation en seringues de MENKE et STEINGASS a ensuite été utilisée pour quantifier la production de gaz des résidus de la prédigestion. Les expériences, réalisées au moyen de porcs en croissance, ont porté sur la quantité et le mode de filtration des substrats prédigérés par la pepsine-pancréatine, l’identification d’un aliment de référence, la dilution des inoculi dans la solution tampon en seringues et la comparaison des fermentations, en utilisant comme inoculi des contenus d’intestin ou des matières fécales. Les résultats montrent que la répétabilité de la digestion in vitro par la pepsine-pancréatine est satisfaisante et que les quantités d’aliment incubées peuvent être augmentées par rapport à la méthode de référence. La filtration des résidus peut être réalisée sur creusets filtrants ou sur toile Nylon. La pulpe de betterave constitue un aliment témoin idéal. Après 24 h d’incubation, la production de gaz obtenue à partir d’inoculi fécaux dilués 20 fois dans la solution tampon est identique à celle enregistrée à partir d’inoculi intestinaux dilués 10 fois dans le même tampon.

The implantable programmable micropump is an interesting solution to treat chronic diseases such as diabetes with regular micro-injections of medicine. However, current applications of micropumps are limited by their rather expensive cost. The challenge is therefore to develop a low cost alternative by reducing the number of parts and by simplifying the assembly. As the pump and its tank will be placed under the skin in order to increase comfort, such a system should be small and reliable. In this paper, we present the micropump we developed within the framework of the 4M-µ pump interuniversity project (Methods and Means for the Miniaturization of Machines). [less ▲]

Apprendre à lire dans une langue n’interfère pas avec l’apprentissage de la lecture dans une autre langue mais prépare plutôt le terrain pour apprendre à lire dans une autre langue. Comme dans le langage oral, il peut y avoir quelques « mixing » de prononciation au niveau des mots qui disparaissent progressivement au fur et à mesure que les langues se compartimentalisent. Avec le temps, l’enfant apprendra également que des mots qui s’écrivent de la même manière dans les deux langues peuvent se prononcer de manière différente. Une recherche menée sur des enfants francophones Belges suivant un programme d’immersion scolaire en anglais et ayant appris à lire en anglais confirment ces observations. 150 enfants âgés de 7 à 12 ans fréquentant ce programme ont été testés sur leurs compétences en lecture du français (décodage et compréhension). Leurs performances (type et nombre d’erreurs, vitesse de lecture) ont été comparées à celles d’enfants francophones fréquentant un enseignement unilingue. Leurs habiletés métaphonologiques (manipulation de la rime et du phonème) ont également été testées. [less ▲]

The coronal abundances of chromospherically active binaries have come under close scrutiny in recent years thanks to several X-ray satellites such as XMM or Chandra. Unfortunately a detailed analysis of the chemical fractionation processes that are possibly operating between the photosphere and the corona is plagued by the lack of reliable and accurate photospheric abundance determinations. In particular a detailed investigation of the photospheric metal content seems worthwhile in the light of several studies that have questioned the customary use of photometric indices as effective temperature indicators in active binaries. We shall present our ongoing effort to determine in a self-consistent way accurate physical parameters and photospheric abundances for a large number of systems and discuss the implications of our results on their abundance patterns and evolutionary status. Preliminary results suggest that these systems are not as iron-deficient as found in previous studies and indicate an overabundance of several key elements (e.g. Na Mg Al Ca) with respect to the solar pattern.

Asteroseismology is one of the major important science topics in astrophysics in the coming decade. Several recent breakthroughs have indeed been made in Europe in this field. The observational data will improve significantly in the near future, as upgraded ground-based instruments are being built and two European asteroseismic space missions are planned for launch between 2005 and 2008. They will provide us for the first time with ultra-high-accuracy, high-temporal resoluton data from space for stars other than the Sun. A successful asteroseismic study involves many different steps, from state-of-the-art raw data treatment to theoretical physical modelling of the oscillation frequencies. Our network is set up to meet the needs of combining and exchanging the different expertises of the participating institutes, of training PhD students and of both training and exchanging post-doctoral researchers. This will guarantee the most fruitful and efficient exploitation of the very substantial investments that are being made in Europe in future observations of stellar oscillations, strengthening Europe's leading position in this research field. Also, it will be a test-bed for the development of efficient procedures for collaboration across the internet, involving a vast range of procedures and skills, as well as extensive common use of a broad variety of data. Furthermore, procedures will be incorporated for the joint training of students, which is an essential part of our project. [less ▲]

Space experiments which are aiming towards asteroseismology and the detection of exoplanets, like COROT or MOST, Eddington and Kepler, are designed to deliver high precision photometric data. Obviously, they can be used also for other purposes than the primary science goals and in addition many other targets can or will be automatically observed simultaneously with the primary targets. As a consequence, fascinating possibilities for additional (parallel, secondary) science projects emerge. For COROT a dedicated working group was thus established with the goal to contribute any useful information which may optimize the scientific output of the mission. [less ▲]

For delta Scuti stars, phase differences and amplitude ratios between the relative effective temperature variation and the relative radial displacement can be derived from multicolor photometric observations. The same quantities can be also calculated from theoretical non-adiabatic pulsation models. We present here these theoretical results, which indicate that non-adiabatic quantities depend on the mixing length parameter alpha used to treat the convection in the standard Mixing Length Theory (MLT). This dependence can be used to test and to constrain, through multicolor observations, the way MLT describes convection in the outermost layers of the star. We will use the equilibrium models provided by the CESAM evolutionary code. The pulsational observables are calculated by using a non-adiabatic pulsation code developed by R. Garridon and A. Moya. In the evolutionary and pulsation codes, a complete reconstruction of the non-grey atmosphere (Kurucz models) is included. The interaction between pulsation and atmosphere, as described by Dupret et al. (2002), is also included in the code. [less ▲]

During the last decade, recurrent epizootics have affected harbour seal (Phoca vitulina) populations in the North Sea. The trace metal levels of the harbour seal in the Southern North Sea are poorly known. In this study, trace metal concentrations (Zn, Cu, Fe, Cd, Hg and Se) were measured in tissues (liver, kidney and muscle) of 72 harbour seals collected along the coasts of France, Belgium and Netherlands between 1994 and 2004. Hg levels were significantly higher in seals from the Southern North Sea than in seals from Norwegian waters (1) probably due to the amount of anthropogenic inputs in the North Sea. Hepatic Hg was positively correlated to hepatic Se, both increasing with the length of the seals. Such a relationship reflects an age accumulation process coupled to a detoxication mechanism involving antagonism between Hg and Se in the liver. Increasing Zn and Hg hepatic levels were observed with degrading body condition of the harbour seals, which is reflected by decreasing blubber thickness and high hepatic to total body mass ratio. Body condition was particularly poor in seals which died from infectious diseases. These observations tend to indicate a global redistribution of trace metals from muscle and blubber to liver, as a result of protein and lipid catabolism linked to disease and starvation. [less ▲]

This paper describes a new approach used by Hydro-Québec to determine the rules of automatic devices installed in its main power plants to maintain secure operation under extreme contingencies. An example of application of this approach is given to illustrate how to apply data mining technique for the rules of the automatic generator rejection and remote load shedding system (RPTC: Rejet de Production et Télédélestage de Charges in French) installed at the Churchill Falls hydroelectric power plant (5500 MW) in Labrador. Real time snapshots of the Hydro-Québec power system collected over several years data have been used to generate large amounts of results (database) by transient stability simulations. The database is processed by the data mining software developed by the University of Liege to construct the decision trees. This approach gives the most relevant parameters and finds optimal settings for the RPTC system at the Churchill Falls, minimizing the number of generator rejection while maintaining the same performance in terms of security coverage. New operation rules have thus been established. [less ▲]

For five years, a postgraduate program in Educational and Training Technology has been developed by both Universities of Liège and Namur (Belgium). This program addresses already graduated adults having a training background. Depending on his/her training experience and a personnal project, the participant has the opportunity of developing different competencies profiles like: educational designer, designer and manager of training systems integrating ICT, e-tutor or trainer in e-learning environments, designer and producer of information or learning multimedia products. The plan of action articulates face-to-face and distance activities. It is based on several principles like definition and follow-up of a personal learning project, clarification of the actors’ roles, systematical use of technologies, active pedagogical methods and quality process. The authors present a series of scenarios including several types of distance activities. On the one hand, they illustrate these activities, insisting on their target goals, their meaning and usefulness, their development and their evaluation criteria. On the other hand, they discuss the organization of face-toface, blended or distance activities taking into account different sides of a learning system in order to stimulate the thought of designers and animators of such learning environments.

This paper describes the main concepts of the stress-strain interpolation model that has been implemented in the non-linear finite element code Lagamine. This model consists in a local description of the yield locus based on the texture of the material through the full constraints Taylor’s model. The prediction of the Swift effect is investigated: the influence of the texture evolution is shown up. The LAMEL model is also investigated for the Swift effect prediction. [less ▲]

L’objectif de ce travail est d’étudier, dans les conditions réelles de production, la variabilité de la qualité technologique, organoleptique et microbiologique de la viande de porc et d’objectiver les relations qui peuvent exister entre les variables évaluées. L’analyse en composantes principales a permis de mettre en évidence des groupes de variables et de visualiser les relations qui peuvent exister entre ces variables. La première composante principale est corrélée aux variables relatives à la qualité technologique et organoleptique de la viande. Elle met en opposition le pH45 d’une part et les paramètres L*, b* et Cond45 d’autre part. La deuxième composante principale peut être considérée comme un axe de qualité microbiologique. L’analyse en composantes principales a également permis de mettre en évidence des groupes d’individus. A titre d’exemple, les génotypes halothane ont pu être différenciés sur ce type de représentation de la variabilité de la qualité de la viande. [less ▲]

Intermodal freight transport is the movement of goods in one and the same load unit or vehicle by successive modes of transport without handling of the goods themselves when changing modes (European Conference of Ministers of Transport et al. 1997). Altough it has still a small market share compared to road transport, it becomes more and more apparant that intermodal transport transport will play an important role in the future. Intermodal transport is more environmental friendly than road transport (Kreutzberger et al., 2003) and has a positive effect on the congestion problems (Van Schijndel and Dinwoodie, 2000). A third and important positive feature of intermodal transport is that it can easily fit in the supply chain management efforts by the companies. In this paper the missing links and opportunities for the intermodal transportsector are analysed. Also solutions for overcoming these bottlenecks are proposed. [less ▲]

Bovine pregnancy-associated glycoproteins (bPAGs) are secreted by binucleate cells of the placenta and can be assayed in maternal plasma as indicators of pregnancy and markers for the functional status of the trophoblast. The concentrations of PAGs vary differentially during the peri-implantation period. Large offspring syndrome (LOS) and abnormal placentation have been associated in cloned fetuses with abnormally increased pregnancy-specific protein 60 (PSP60). The aim of this study was to investigate the evolution of plasma levels of PAGs measured by the use of three different RIA systems in heifers after transfer of somatic cloned embryos and to compare that to plasma levels of control recipients during early pregnancy to distinguish which ones vary differentially. Cloned embryos were derived from nuclear transfer from fibroblasts of an adult cell line to in vitro-matured bovine oocytes according to Vignon et al. (1998 Theriogenology 49, 392). Control embryos were obtained in vitro after IVF and cultured in serum-free medium up to the blastocyst stage. By Day 7, cloned (n = 29) and control embryos (n = 10) were transferred to synchronous recipient heifers of the Normande breed (one embryo per recipient). Blood samples were taken every 2–3 days between Days 25 and 50 of pregnancy from recipients that had a positive progesterone test on Day 21, and the plasma was stored frozen until assay. Pregnancy status was monitored by repeated ultrasound scanning from Day 35 to Day 90. Concentrations of PAGs were determined by validated RIA assays for the different forms (PAGI67, PAG55+62, PAG55+59) using 3 antisera (AS 497, AS 706, AS 708, respectively) (Perenyi et al. 2002 Reprod. Domest. Anim. 37, 100–104). profiles of only the recipients that were confirmed pregnant by scanning over Day 50 (n = 18 clones, n = 4 controls) were analyzed and compared. Concentrations of PAGs measured by AS 497 and AS 706 were significantly higher in clones than in control recipients during the second month of pregnancy, indicating that the placenta of clones secreted these forms in a different manner compared to controls. Moreover, we found that concentrations of PAGs as determined with the two same antisera were higher for recipients with a cloned fetus that developed to term compared to those which had fetal loss before 3 months. For instance, using the AS 706, respective values of PAGs at Day 45 were 17.64 ± 7.59 and 10.96 ± 6.38 ng/mL for pregnancies with cloned and control fetuses, respectively, (P < 0.05) and 21.29 ± 4.77 and 12.88 ± 8.90 ng/mL in pregnancies with cloned fetuses that developed normally to term or died before 3 months of age, respectively, (P < 0.05). We conclude that our assays using two antisera could be a predictive test for fetal loss in clone pregnancies. Until now, recipients carrying cloned embryos that develop LOS during late pregnancy could not be detected by conventional assays in maternal serum or by scanning during the period of 35–50 days. This study provides a new diagnostic tool to detect them. Investigations are in progress to check the localization of these different forms of PAG in placentomes removed from recipients carrying somatic clones. [less ▲]

This paper deals with the application of statistical process control techniques based on principal component analysis to vibration-based damage diagnosis of structures. Principal component analysis of the sensor time-responses allows to extract principal directions (i.e. features) which define a subspace that is representative of the dynamics of the instrumented structure. Any change in the response of a single sensor will affect the subspace spanned by the complete sensor response set. It follows that the subspace corresponding to the current state of the structure can be compared to the subspace of the initial state of the structure, assumed to be healthy, in order to diagnose possible damage. Principal component analysis may also be performed for every potential subset of damaged sensors in order to identify the involved sensor, and, therefore, the damaged substructure. In this paper, the problem of structural damage detection is addressed in the case of environmental vibration testing. A direct application is presented for a test item submitted to random vibration testing by means of an electro-dynamic shaker. [less ▲]
