Résumé :

Partant de la constatation que le parcours de Thomas More est, en de nombreux points, semblable à celui de Pic de la Mirandole, je cherche à determiner en quoi Pic a pu être un modèle pour More. Une brève analyse de The Life of Pico me permet en particulier de poser la question de la fidélité de More par rapport à son modèle et d’évaluer l’influence de Pic sur la carrière littéraire de More tout en montrant l’ambiguïté de leurs relations.

Résumé :

Objectif : Créer et valider un modèle de CAE normal par impression en 3D bio-fidèles aux CAE humains. Méthodologie : Nous avons prélevé dix CAE humains sur des pièces anatomiques. Après acquisition volumique sur un scanner conventionnel, la conception numérique des CAE en 3D comportait une segmentation et la mise en place d’un support tympanique. Nous avons utilisé du PLA pour l’impression et du ruban adhésif pour simuler une MT artificielle. La vélocimétrie de l’umbo a été mesurée au moyen d’un laser couplé à une chaine acoustique de stimulation-recueil dédiée. Résultats : Comparés aux CAE humains, les modèles ont montré des réponses identiques statistiquement. Un second pic était observé à 5 kHz sur le pattern des CAE imprimés. Les hautes fréquences montraient un profil plus chaotique. Conclusion : Les CAE imprimés en 3D sont des modèles valides et bio-fidèles aux CAE humains. La normalisation des amplifications observées permet d’obtenir un modèle utile pour l’optimisation des dispositifs d’amplification ou de protection auditifs.

Résumé :

Le masque en béton bitumineux est l'un des organes les plus utilisés pour l'étanchéité des barrages en remblai. Le parement en béton bitumineux est, en particulier dans le cas des installations de stockage par pompage hydroélectriques, sont souvent très exposé à des fluctuations importantes de température, qui sont causées par la radiation solaire, la variation du niveau d'eau dans le réservoir, par le gel dans la saison d'hiver, ainsi que la vitesse et la direction du vent, sans oublier les précipitations. Pour mieux expliquer le phénomène de transfert de chaleur, il est nécessaire de connaître les variations de température dans les différentes couches du masque en béton bitumineux. Ce travail décrit la mesure de la température dans le masque en béton bitumineux (brut et avec protection) du barrage Ghrib (Ain Defla, Algérie) et son évaluation à l'aide d'un modèle numérique du transfert de chaleur dans le parement en béton bitumineux en utilisant le logiciel Fluent. Dans un premier temps une validation du modèle par comparaison avec des mesures expérimentales, dans le cas d'une variation journalière de température ambiante, La comparaison des résultats du calcul du modèle numérique avec les mesures réelles montre une excellente ressemblance. Nous simulons ensuite la pose d'une protection thermique en ajoutons une couche convective en béton poreux. Les résultats de cette simulation montrent que le transfert de chaleur par convection possède le potentiel de développer une différence de température significative entre les parties inférieure et supérieure du masque, et aussi que l'ajout de cette couche permet d'amortir le pic de température et le réduire à 12,31 °C, ceci de 9 h jusqu'à 15 h au moment où la chaleur est très élevée, ce qui est significatif pour notre masque, où les températures atteignant leurs valeurs maximales (49 °C).

Résumé :

Les taux de mésothéliome sont à la hausse à l’échelle mondiale, mais les tendances en Alberta sont encore peu connues. Les auteurs de la présente étude descriptive basée sur une population se sont servis des données de 1980 à 2004 du registre de l’Alberta Cancer Board afin d’élaborer un modèle âge-période-cohorte de l’évolution dans le temps de l’incidence du mésothéliome pleural chez les hommes. Les taux d’incidence sont influencés à la fois par l’âge et par la cohorte. La cohorte des hommes nés entre 1930 et 1939 présente le risque le plus élevé, ce qui coïncide avec une utilisation répandue de l’amiante, et donc une exposition importante, à partir des années 1940 au Canada. Nous prévoyons qu’entre 1980 et 2024, 1 393 hommes albertains de 40 ans et plus mourront d’un mésothéliome pleural, dont 783 (56,2 %) entre 2010 et 2024. Une fois tous les groupes d’âge, les deux sexes et les divers sièges de la maladie pris en compte, le nombre total de décès en Alberta causés par un mésothéliome sera plus grand. Il atteindra sûrement un pic entre 2015 et 2019. En plus des efforts constants axés sur l’élimination des maladies liées à l’amiante en Alberta, l’enjeu majeur est la mise en place de systèmes de surveillance pour la prévention d’épidémies de cancers professionnels évitables en Alberta.

Résumé :

Entre 1991 et 2003, 75 650 données sur la production laitière journalière de vaches Frisonnes de la station de Mahwa ont été collectées pour étudier les effets de la durée de lactation, de l’âge au vêlage, de l’année et du mois de lactation, et de la parité sur cette production. Les données ont été analysées à l’aide d’un modèle linéaire (procédure GLM de SAS). Tous les facteurs ont influencé significativement la production laitière (P < 0,001). La moyenne générale a été de 8,71 l/jour. La production laitière a suivi la courbe théorique de lactation avec un pic de lactation de 11,48 ± 0,20 l/jour au 15e jour de lactation. L’âge au vêlage a influencé la production, avec des coefficients de régression linéaire et quadratique de –0,26 l/mois et 0,0052 l/mois² en première parité, de 0,49 l/mois et –0,0056 l/mois² en deuxième parité, et de –0,22 l/mois et 0,0013 l/mois² en troisième (et plus) parité. La production laitière a diminué au cours des années de lactation avec la chute la plus importante en 1993. Elle a atteint un minimum en 1995 avec 6,91 ± 0.17 l/jour et un maximum en 1991 avec 15,55 ± 0,45 l/jour. Elle a été significativement plus élevée en février (9,75 ± 0,13 l/jour) au milieu de la saison pluvieuse qu’en septembre (7,60 ± 0,13 l/jour) en fin de saison sèche. La moyenne des moindres carrés pour la production laitière journalière a été respectivement de 11,47 ± 0,30, 5,23 ± 0,09, et 10,11 ± 0,06 l/jour en première, deuxième et troisième (et plus) lactation.

Résumé :

In this article, we first review the current status of 400GBASE client-side optics standards and multi-source agreements (MSAs). We then compare different form factors for 400GE modules, including CFP8, OSFP and QSFP-DD. The essential techniques to implement 400GE, such as pulse amplitude modulation (PAM4), forward error correction (FEC) and a continuous time-domain linear equalizer (CTLE), are discussed. A 400GE physical interface card (PIC) in Juniper’s PTX5000 platform has been developed, conforming to the latest IEEE802.3bs standard. To validate the PIC’s performance, a commercial optical network tester (ONT) and the PIC are optically interconnected through two CFP8-LR8 modules. The CFP8-LR8 module utilizes eight optical wavelengths through coarse wavelength division multiplexing (CWDM). Each wavelength carries 50 Gb/s PAM4 signal. The signal transmits through 10 km of single mode fiber (SMF). The ONT generates framed 400GE signal and sends it to the PIC through the first CFP8 module. The PIC recovers the signal, performs an internal loopback, and sends 400GE signal back to the ONT through the second CFP8 module. The optical spectrum, eye diagram, receiver sensitivity, long time soaking results, and internal digital diagnosis monitoring (DDM) result are fully characterized. The pre-FEC bit error rate (BER) is well below the KP4 FEC threshold of 2.2 × 10−4. After KP4 FEC, error-free performance over 30 km of SMF is achieved. In this way, we demonstrate both the interoperation between the PIC and the ONT, as well as the interoperation between the two CFP8 modules. This demonstration represents the successful implementation of the 400GE interface in the core IP/MPLS router.

Résumé :

Dans la zone Caraïbe, les chèvres sont principalement élevées pour la viande en système allaitant. Peu de références bibliographiques portent sur la caractérisation des chèvres locales en milieu tropical. Cette étude présente une synthèse des performances zootechniques de la chèvre Créole allaitante en Guadeloupe dans un troupeau expérimental de l’INRA. Le troupeau est conduit toute l’année au pâturage de façon intensive (conduite de la reproduction, prophylaxie, fertilisation, irrigation, charge animale). Les performances de reproduction ont été analysées à partir d’une banque de données portant sur 599 femelles ayant réalisé 1904 mise bas. La première mise bas intervient à 17,2+3,1 mois et l’intervalle moyen entre mise bas est de 8,5 mois. Le taux moyen de fertilité est souvent supérieur à 90 %. La taille moyenne de la portée est de 2,1 chevreaux par mise bas. Plus de 80 % des mise bas donnent des portées d’au moins 2 chevreaux nés vivants et 95 % des mise bas n’ont jamais eu de morts nés. La taille de la portée augmente régulièrement avec le rang de mise bas jusqu’à la 5ème, de 50 % depuis la première. Les caractéristiques de la production laitière sont décrites à partir de 145 lactations estimées par la méthode ocytocine dans différents essais d’alimentation. La production laitière moyenne ajustée pour les principaux facteurs de variation est de 792+206 g/j. Les courbes de production présentent un pic de lactation précoce, en 2ème semaine de lactation, et de faible niveau : 550 et 1020 g/j pour les chèvres allaitant des simples et des doubles respectivement. Le taux butyreux moyen est de 5 %. Les performances de croissance avant sevrage ont été analysées sur 6375 chevreaux. Les données présentées sont ajustées pour les principaux facteurs de variation du modèle : le sexe, la taille de la portée, le rang de mise bas, l’année et la saison de mise bas. Le taux de mortalité moyen est de 15,7 %. Les poids à la naissance et au sevrage (réalisé à un âge moyen de 82+15 j) sont de 1,73+0,34 kg et 7,75+1,76 kg respectivement. Ils varient selon la taille de la portée et le sexe : 15 % de différence entre les simples et les multiples et 10 à 8 % de variation entre mâles et femelles. Le gain moyen quotidien entre 10 et 30 jours (GMQ10-30) et le GMQ40-70 sont de 84,3 + 25,9 et 65,7 + 24,0 g/j respectivement. Il apparaît que la chèvre Créole se classe parmi les meilleurs génotypes tropicaux à viande du fait de ses grandes capacités de reproduction, ses qualités maternelles et les niveaux de croissance présevrage observés.

Texte intégral

Résumé :

The 1.3-megadalton transcription factor IID (TFIID) is required for preinitiation complex (PIC) assembly and RNA polymerase II (Pol II)–mediated transcription initiation on almost all genes. The 26-subunit Mediator stimulates transcription and cyclin-dependent kinase 7 (CDK7)–mediated phosphorylation of the Pol II C-terminal domain (CTD). We determined the structures of human Mediator in the Tail module–extended (at near-atomic resolution) and Tail-bent conformations and structures of TFIID-based PIC-Mediator (76 polypeptides, ~4.1 megadaltons) in four distinct conformations. PIC-Mediator assembly induces concerted reorganization (Head-tilting and Middle-down) of Mediator and creates a Head-Middle sandwich, which stabilizes two CTD segments and brings CTD to CDK7 for phosphorylation; this suggests a CTD-gating mechanism favorable for phosphorylation. The TFIID-based PIC architecture modulates Mediator organization and TFIIH stabilization, underscoring the importance of TFIID in orchestrating PIC-Mediator assembly.

Résumé :

This paper examined system identification using grey-box model estimation and position-tracking control for an electro-hydraulic servo system (EHSS) using hybrid controller composed of proportional-integral control (PIC) and model predictive control (MPC). The nonlinear EHSS model is represented by differential equations. We identify model parameters and verify their accuracy against experimental data in MATLAB to evaluate the validity of this mathematical model. To guarantee improved performance of EHSS and precision of cylinder position, we propose a hybrid controller composed of PIC and MPC. The controller is designed using the Control Design and Simulation module in the Laboratory Virtual Instrumentation Engineering Workbench (LabVIEW). A LabVIEW-based experimental rig is developed to apply the proposed controller in real time. Then, the validity and performance superiority of the hybrid controller were confirmed by comparing them with the MPC and PIC results. Results of real-life experiments show improved robustness and dynamic and static properties of EHSS.

With this PIC/MCC code, the multiplication rate of the electron density and the delay time in oxygen breakdown at atmospheric conditions are researched. The results show: the multiplication rate of the electron density is periodic, and its period is the half of the electric field period; the breakdown delay time in the gas breakdown increases while the frequency of electric field or the gas pressure increases.

In particular we give deterministic algorithms that allow the computation of the so-called (σ - 1)-rank and the (σ - 1)2-rank of Pic 0(K), where σ denotes a generator of the Galois group of K/𝔽q(T). In the case l = 2 this yields the exact structure of the 2-torsion and the 4-torsion of Pic 0(K) for a hyperelliptic function field K (and hence of the 𝔽q-rational points on the Jacobian of the corresponding hyperelliptic curve over 𝔽q). In addition we develop similar results for l-parts of S-class groups, where S is a finite set of places of K. In many cases we are able to prove that our algorithms run in polynomial time.

Résumé :

A ring R is called right PCI if every proper cyclic right R-module is injective, i.e. if C is a cyclic right R-module then CR ≅ RR or CR is injective. By [2] and [3], if R is a non-artinian right PCI ring then R is a right hereditary right noetherian simple domain. Such a domain is called a right PCI domain. The existence of right PCI domains is guaranteed by an example given in [2]. As generalizations of right PCI rings, several classes of rings have been introduced and investigated, for example right CDPI rings, right CPOI rings (see [8], [6]). In Section 2 we define right PCS, right CPOS and right CPS rings and study the relationship between all these rings.

Résumé :

The Portable Beverage Cooler (PBC) has been designed to satisfy the need of cooler apparatus that could be carried easily. The utilization of this apparatus was intended to minimize the environmental damage affected by vapour compression refrigeration system using CFCs Refrigerant. The peltier effect from thermoelectric module was utilized in this PBC and called as Thermoelectric Cooler (TEC). Furthermore, heat-sink and fan were needed to ensure the cooling effect continously worked. To achieved the objectives of this machine (portable, environment-friendly, low watt, affordable), the design consideration are heat load, insulating material, weight of components, electric consumption, and dimension of the cooling box. The results of the design shows the PBC cooling box dimension is 6 cm x 6.5 x 15 cm. The insulation of the PBC cooling box are polyurethane foam and polystyrene expanded with thickness 6 mm and 5.3 mm, respectively. The alumunium plate was applied as inner wall to enhance the cooling capacity of cooling room temperature. In this PBC was used one stage of TEC that could yield cooling room temperature until 15 oC in 30 minutes operation by consuming 20 W of electricity.

Résumé :

This paper aims to present a smart, particle swarm optimization (PSO)-based, real time configuration strategy for a photovoltaic (PV) module array in the event of shadow cast on a PV module(s) and/or module failure as an effective approach to power generation efficiency elevation. At the first step, the respective maximum output power levels provided by a normal operating array at various levels of irradiation and module surface temperatures are measured and entered as references into a database. Subsequently, the maximum output power (MPP) level, tracked by a MPP tracker, is feedbacked for a comparison with an aforementioned reference as a way to tell whether there is either a shadow or a malfunction event on a PV module(s). Once an abnormal operation is detected, the presented smart configuration algorithm is performed to reconfigure the PV module array such that the array is operated at the global MPP as intended. Furthermore, by use of a PIC microcontroller that is a family of microcontrollers made by Microchip Technology for compact implementation, this study is experimentally validated as an effective approach to locating the global MPP at all events.

Résumé :

The RT-LAB real-time simulation software can expediently and rapidly apply the Simulink model to the hard-in-the-loop simulation system and greatly save the expenses for development, experiment and measurement, thus cutting down the development cycle. The use of the self-made PCI board in the RT-LAB software requires the development of its driver module by the user himself. This paper presents the idea and development processes of the PCI bus-based board driver with the RT-LAB software. Taking as an example the NI-6230 multifunctional data acquisition board driver, the paper also presents the PCI board driver's key codes and their compilation with the RT-LAB software.

Résumé :

The development of a teaching aid module for digital Signal processing (DSP) in Nigeria Universities was undertaken to address the problem associated with non-availability instructional module. This paper annexes the potential of Peripheral Interface Controllers (PICs) with MATLAB resources to develop a PIC-based system with graphic user interface environment suitable for data acquisition and signal processing. The module accepts data from three different sources: real time acquisition, pre-recorded data acquisition and software-generated data. The developed system is able to perform analysis on both stationary and non-stationary signals using Fast Fourier Transform (FFT) and Short Time Fourier Transform (STFT). The STFT-based approach provides Improved Joint Time Frequency Analysis (IJTFA) of signals. A graphical user interface (GUI) was developed to create interactive environment for understanding the operations of digital signal processing. The developed system not only provides interactive platform for data acquisition, spectral analysis and filter design but also makes it avoidable to students in Nigeria University.

Résumé :

According to the voltage balance equation, the paper deduces the mathematical model of BLDCM on the basis of analyzing the operation principle. In SIMULINK environment, the BLDCM ontology module is built by adopting the combination of BLDCM state equation with S function method. The built motor ontology module proves to be accurate and reasonable through the analysis of the simulation waveform, which helps to analysis BLDCM electronic commutation, etc. Again taking LM621N as commutation control chip, using PIC microcontroller output variable frequency square wave, and through external input device to adjust the square wave frequency, thus realizes the control of motor speed. A brushless dc motor drive with circuit protection functions is designed by the method of combining hardware and software. Not only the motor work situation of ontology is intuitively reflected, and the development cycle is shorted.

Résumé :

This study aimed to enhance boron removal through powdered activated carbon adsorption (PAC) and application of a micro-filtration (MF) process as a pretreatment of a seawater reverse osmosis (SWRO) process. Batch and continuous experiments were conducted to investigate the effect of membrane filtration as well as PAC addition on boron removal in reconstituted seawater. In batch test, two kinds of polyvinylidene fluoride (PVDF) hollow fiber membrane, Module A and Module B, were used to assess the influence of pH and PAC on boron removal, whereas in continuous mode, two MF systems with submerged PVDF flat-sheet membrane were run in parallel. Modules A and B obtained the highest percentage boron removal at pH 9 in the batch experiment with an average value of 47.33%, and their concentration of boron was further reduced after addition of PAC increasing the removal to 51.33 and 69.33%, respectively. For the continuous operation, PAC addition decreased the boron concentration by 20–30 and 40% in the reactor and effluent, respectively. On the other hand, only 5% reduction was obtained inside the reactor and 30–40% in the effluent for the system without PAC. Thus, operating the system at high pH with PAC addition could enhance the performance of the adsorption-MF system, which can be used as a pretreatment for the SWRO process.

Résumé :

The study was designed as a three-phase approach to reorient Community Health Officers working in Odukpani (one of the first model PHC Centers in Nigeria) toward Primary Health Care: 1) knowledge, attitude, and practice determination; 2) a PHC-based training module; and 3) teacher-learner evaluation. The results strongly suggest that this type of deliberate intervention to remove an identified program constraint, is crucial to the anticipated role of PHC workers as agents of change. The implications of the results for PHC system development in Nigeria are highlighted.
