The proposed concept consists in placing a steel profile with limited size inside the reinforced concrete column of the first level of the building. This profile is not considered for the design and is essen-tially assumed to act as a safety belt activated only in case of deficiencies of the concrete under earthquake action, providing thus the requested robustness and limiting the risk of soft-storey mechanisms even in the most unfavorable conditions. Theoretical, experimental and numerical investigations summarized in the pre-sent contribution are aiming at demonstrating the efficiency of the concept. [less ▲]

Bottom friction modelling is an important step in river flows computation with 1D or 2D solvers. It is usually performed using empirical laws established for uniform flow conditions or a modern approach based on turbulence analysis. Following the definition of the flow validity field of the main friction laws proposed in the literature, an original continuous formulation has been developed. It is suited to model river flows with a wide range of properties (water depth, discharge, roughness…). The efficiency of this new formulation, theoretically established and numerically adjusted, is demonstrated through various practical applications. [less ▲]

The dynamic behaviour of a spur gear pair can be studied in terms of transmission error considering a single degree of freedom system. Thus, a mechanical system exhibiting combined parametric excitation and clearance type nonlinearity is examined by means of numerical integrations and continuation methods in an effort to explain its complex behaviour, as it is commonly observed in the steady state forced response of rotating machines. The specific case of a preloaded mechanical oscillator having a periodically time varying stiffness function and subject to a symmetric backlash condition is considered. Even if such an oscillator represents the simplest model able to analyze a single spur gear pair, it exhibits a complex dynamic scenario, namely jumps, superharmonics, subharmonics resonances and dynamic bifurcations. In order to reduce the vibration of the system, a nonlinear absorber is applied. Unlike common linear and weakly nonlinear systems, systems with strongly nonlinear elements are able to react efficiently on the amplitude characteristics of the external forcing in a wide range of frequencies. A strongly and essentially nonlinear, lightweight, with cubic stiffness oscillator is then attached to the main nonlinear system under periodic parametric forcing and the feasibility of a possible application of this nonlinear energy sink (NES) for vibration absorption and mitigation is checked.

In this paper, an integrated modelling methodology for the assessment of population exposure to air pollution, involving all compartments of the DPSIR-concept, is illustrated by an application in The Netherlands. The application demonstrates the advantages of an activity-based approach by presenting three kinds of applications: the calculation of vehicle emissions, the simulation of pollutant concentration patterns and the assessment of the population exposure to air population. Understanding exposure variations among activities and subpopulations can be very useful for scientific and policy purposes: it can provide information on locations or population groups most at risk, or can indicate where and when the largest exposure values occur.

Currently efforts are underway to introduce molecular information into genetic evaluation systems. A particular situation is genomic selection however simpler cases exists where major genes are known and used by breeders. A new alternative strategy for the prediction of gene effects and especially their smooth integration into genetic evaluations based on an equivalent method was developed from existing theory. Underlying hypothesis were based on the idea that knowledge of genotypes will not affect overall additive genetic variance but only change expected values of genetic effects for animals with known genotypes. The developed equations were modified to allow that not all animals were genotyped. As the underlying mixed model is open a very large range of models can be used in situations including random regression models, multipletrait, maternal effects and multiple-across-country-evaluation models. Computations involved successive solving of two mixed models, with the use of an linear extrapolation to speed up convergence of gene effects. The method was tested for several known major genes and QTL, e.g. for the mh gene in the dual-purpose Belgian Blue population in Belgium. Modifications of the method could also be developed to be useful in the context of genomic selection. [less ▲]

This paper introduces a novel algorithm for approximate policy search in continuous-state, discrete-action Markov decision processes (MDPs). Previous policy search approaches have typically used ad-hoc parameterizations developed for specific MDPs. In contrast, the novel algorithm employs a flexible policy parameterization, suitable for solving general discrete-action MDPs. The algorithm looks for the best closed-loop policy that can be represented using a given number of basis functions, where a discrete action is assigned to each basis function. The locations and shapes of the basis functions are optimized, together with the action assignments. This allows a large class of policies to be represented. The optimization is carried out with the cross-entropy method and evaluates the policies by their empirical return from a representative set of initial states. We report simulation experiments in which the algorithm reliably obtains good policies with only a small number of basis functions, albeit at sizable computational costs. [less ▲]

The present study describes the phytochemical profile Antioxidant and cytotoxicity activity of Lavandula dentata essential oil, collected in eastern Morocco (Taforalt). The sample of essential oil was obtained from the aerial parts of the plant by hydrodistillation and analyzed by GC–MS. The in vitro cytotoxicity of the oil on the cancer cell lines PC-3 (prostate), V79 (fibroblaste) and normal P388D1 (murine macrophage) was examined. We have shown that the oil had negligible cytotoxic effects against all cell lines tested. The oil was also found to possess antioxidant activity as demonstrated by the 1,1-diphenyl-2- picrylhydrazyl (DPPH) radical method. Lavandula dentata essential oil has promising potentials for incorporation into various food, cosmetic and pharmaceutical products for which a natural aroma, colour, antioxidant and antimicrobial additive is desired.

In today’s urbanising world, effective urban management and planning strategies are needed to temper the impact of urban change processes on the natural and human environment. To develop and monitor such strategies, and to assess their spatial impact, analysing changes in urban structure is essential. Data from earth observation satellites provide regular information on urban development and, as such, may contribute to the mapping and monitoring of cities and the modelling of urban dynamics. Especially images of medium resolution (Landsat, SPOT, …), which are cheap, widely available and often part of extensive historic archives, offer a wealth of information that may be useful for urban monitoring purposes. The lower resolution of this type of imagery, however, hampers the study of urban morphology and change processes at a more detailed, intra-urban level. Spectral unmixing approaches, which allow characterising land-cover distribution at sub-pixel level, may partly compensate for this lack of spatial detail, and may render medium-resolution imagery more useful for urban studies. The main research question addressed in this paper is how medium-resolution imagery could be used to describe urban morphology, by combining spectral unmixing approaches with spatial metrics. Spatial metrics derived from satellite imagery may be useful to quantify structural characteristics of expanding cities, and may provide indications of functional land use. In this study, we develop a set of urban metrics for use on continuous sealed surface data produced by sub-pixel classification of Landsat ETM+ imagery. Two sub-pixel classification approaches are examined for that purpose. In a first approach, we use a linear spectral mixture model with a vegetation and a non-vegetation endmember to deconvolve each pixel’s spectrum into fractional abundances of the two end member spectra, which are determined by visualising mixture space with principal component analysis. In a second approach, we use a linear regression model to estimate the proportion of vegetation cover within each Landsat pixel. In both approaches, an urban mask is used to indicate pixels belonging to urban land cover. Only pixels within the urban mask are subjected to sub-pixel classification. We hereby assume that the urban area does not contain bare soil and that the area of a pixel not covered by vegetation fully consists of sealed surface cover. The resulting sealed surface proportion map is then used to characterise urban morphology and land use by means of the shape of the cumulative frequency distribution of the estimated sealed surface fractions within a building block. A transformed logistic function is fitted to this distribution with a least-squares approach to obtain function parameters that are used as variables in a supervised classification approach, together with spatially explicit metrics (spatial variance and Moran’s I). Our study demonstrates that images from medium resolution sensors can be used to characterise intra-urban morphology, and that the structure of a building block as described by the proposed metrics gives an indication of its membership to certain morphological/functional urban classes. In future research we will incorporate socio-economic data in the metric analysis to further improve the distinction of urban land-use categories. The spatial metrics approach developed in this study will be used in experiments to improve the calibration of the MOLAND urban growth model, which is currently calibrated with historical land-use maps available for approximately 10-year intervals.

Au début du XVIe siècle, plusieurs artistes actifs en France empruntent des motifs à l'art de Léonard de Vinci. L'analyse de ces réminiscences léonardesques montre que plusieurs d’entre elles paraissent dans des ouvrages issus du milieu royal, réalisés principalement dans les années 1515-1530. La présence de ces échos s’explique par le fait qu’à cette époque les relations entre le maître italien et la royauté française sont fortement établies ; de plus, de nombreuses peintures de Léonard sont alors conservées en Touraine ; enfin, le souvenir du maître dans ces régions - l’Italien est mort au Clos Lucé en 1519 - est encore vif. Dès lors, dans la première moitié du xvie siècle, les rois de France ont-ils utilisé la personnalité et les peintures de Léonard pour garantir leur programme culturel ? Nous le pensons puisque François Ier fait venir l'Italien en France. De plus, après lui avoir offert un logement et une pension confortables, il rassemble un ensemble exceptionnel de ses tableaux. En outre, l’art de Léonard s’avère l'une des sources d'inspiration des artistes actifs en Touraine, comme si le maître avait alors constitué un lien entre l'art italien et la nouvelle création française. Ainsi, en protégeant Léonard, en acquérant ses peintures et en commandant des œuvres qui présentent des réminiscences à son art, François Ier devient un mécène exceptionnel, le digne « Père des arts et des lettres ».

Introduction : Un déficit en mémoire épisodique est caractéristique dans la maladie d’Alzheimer (AD) et chez les patients âgés présentant une altération cognitive légère (MCI). Cette altération peut s’expliquer par un déficit d’acquisition et/ou un déficit de consolidation. Toutefois, les modifications cérébrales responsables de ces déficits ne sont pas encore parfaitement élucidées. L’objectif de notre étude était de mettre en relation le profil d’apprentissage déficitaire de ces patients avec leur métabolisme cérébral au repos. Méthode : L’épreuve du California Verbal Learning Test (CVLT) a été administrée à 51 patients AD, 18 patients MCI qui sont restés stables (suivi longitudinal de 18 mois, MCI-S), 16 patients MCI qui ont développé la maladie d’Alzheimer (MCI-C) durant les 18 mois de suivi et 12 participants de contrôle. La mesure d’acquisition est la proportion moyenne de gain à travers les 5 essais d’apprentissage du CVLT. La mesure de consolidation est la proportion totale de pertes à travers ces 5 essais. La mesure du métabolisme cérébral au repos a été effectuée en tomographie par émission de positions (18FDG-TEP). Les mesures de corrélation cognitivo-métabolique ont été réalisées au moyen du logiciel SPM8 (p non-corrigé avec hypothèse a priori <0.001). Résultats : Les groupes AD et MCI-C ont un gain moyen moindre que les groupes MCI-S et contrôles. L’ampleur du gain inter-essais est positivement corrélée à l’activité métabolique au niveau de l’hippocampe postérieur chez les patients AD, à l’activité pariétale inférieure chez les patients MCI-S, et à l’activité frontale postérieure dans le groupe contrôle. Par ailleurs, le groupe AD présente plus de pertes inter-essais que les trois autres groupes. Toutefois, aucune corrélation significative n’apparait entre le total des pertes inter-essais et le métabolisme cérébral. Discussion : Ces données suggèrent que les patients AD, même à un stade très précoce (MCI-C) présentent un déficit d’acquisition de l’information. Ce déficit pourrait être sous-tendu par des perturbations métaboliques dans les réseaux d’apprentissage fronto-pariétaux et hippocampique. Il existe de plus un déficit de consolidation inter-essais spécifique aux patients AD mais ce déficit n’est corrélé à aucune région cérébrale au seuil statistique utilisé. [less ▲]

The aim of this study was to evaluate a field exercise test specifically designed for endurance horses and to determine the relevant parameters allowing discrimination between healthy horses (H) and horses presenting subclinical disorders (SP). Twenty four endurance horses underwent blood analyses, general examination and special exams to define a posteriori 2 groups: group H composed of healthy horses (n=12) and group SP included horses presenting subclinical disorders (n=12). The exercise test consisted of a warm-up followed by 3 gallop steps (27 km, 1.5km, 1.5km) at incremental speed. Lactates were measured after each step, an ECG was recorded during effort and recovery, speed was monitored by a GPS. Significant differences were observed between H and SP groups for VLA4, V160 and heart rate during recovery with better values for H horses. These results demonstrate the pertinence of a medical athletic follow-up in endurance horses: this field exercise test is easily achievable and allows the detection of subclinical disorders which would otherwise remain unsuspected by the riders.

This paper deals with eddy-current effects in the distributed winding of electrical machines, and in particular with the proximity effect and the associated losses. A previously proposed homogenization method for windings in two-dimensional (2D) time-domain finite-element (FE) models is shown to be applicable without additional computational cost, producing a precise estimate of the instantaneous proximity-effect losses. The method is illustrated by considering the conductors in a single stator slot of a 3kW induction motor. The brute-force model, with fine discretisation of each conductor, and the homogenized model yield macroscopic results that are very close to each other. [less ▲]

In many applications of linear regression models, the regression coefficients are not regarded as fixed but as varying with another covariate named the effect modifier. A useful extension of the linear regression models are then varying coefficient models. To link the regression coefficient with the effect modifier, several methods may be considered. Here, we propose to use Bayesian P-splines to relate in a smoothed way the regression coefficient with the effect modifier. We show that this method enables a large level of flexibility: if necessary, adaptive penalties can be introduced in the model (Jullion and Lambert 2007) and linear constraints on the relation between the regression coefficient and the effect modifier may easily be added. We provide an illustration of the proposed method in a PET study where we want to estimate the relation between the Receptor Occupancy and the drug concentration in the plasma. As we work in a Bayesian setting, credibility sets are easily obtained for receptor occupancy, which take into account the uncertainty appearing at all the different estimation steps. [less ▲]

Rapeseed oil (RO) (a choice source of unsaturation-rich residues) was used in the present study to enrich anhydrous milk fat (AMF) with unsaturated C18 fatty acids (FA) (oleic, linoleic and linolenic acids). Comparatively, one “harder” fraction of AMF underwent the same reaction. The physico-chemical properties modifications induced by the reaction were followed. The compositional changes are reported in this first part and the consequent physical modifications are presented in a second part. [less ▲]

Abstract: Processes leading to slope failures are often difficult to describe/understand since they involve complex interactions of seismic, geological and hydro-meteorological factors. To date, we are still puzzled by the triggering of the Kainama loess earthflow in April 26 2004, in the Gulcha region (Kyrgyzstan, Central Asia), in the transitional zone between the Fergana Basin in the north and the Alai Range in the south. Indeed, numerical simulations conducted so far and using the 2D finite difference code FLAC have shown that the ... [less ▲]
