The purpose of this article is to develop an inverse method for adjusting the material parameters during single point incremental forming. The main idea consists in simulating tests performed on the same machine as the one used for the process itself. This reduces the costs of the equipment since no specific and costly standard test equipment is needed. Moreover, it has the advantage that the material parameters are fitted for a heterogeneous stress and strain state occurring during the real process. Before using the inverse method, the numerical results must be compared with the experimental ones. Several boundary conditions will be tested. [less ▲]

The factors affecting the preparation of Au/TiO2 catalysts and their activity in the total oxidation of n-hexane were investigated. The mechanism of gold deposition-precipitation is discussed through comparison of the samples prepared by this method and others prepared by anion adsorption method. The influence of the pH and of the origin of TiO2 support used are additionally addressed. The difference of gold dispersion observed between the two methods is attributed to a difference of mobility of the gold precursors during the thermal treatment rather than to a difference of dispersion over the uncalcined samples. The mechanism of gold deposition-precipitation actually involves the reactions of gold hydroxy-chloride species with the surface. Another pan of the work, thus, concerned the use of the deposition-precipitation method to prepare a Au/MnO2 catalyst. It is shown that the activity of gamma-MnO2 is directly proportional to its surface area and that the deposition-precipitation procedure decreases the surface and activity of MnO2. However, the deposition of gold allows to avoid a too deep sintering of gamma-MnO2 and, thus, helps to somehow preserve its activity. (c) 2006 Elsevier B.V. All rights reserved. [less ▲]

In this paper we show that a recently proposed technique for anti-windup control of exponentially unstable plants can be easily extended to solve the corresponding robust anti-windup problem for linear parameter varying systems, for which the time varying parameters are measured online. For this class of plants, it is shown that the proposed technique is minimally conservative with respect to the size of the resulting operating region: in particular, such a region is (up to an arbitrarily small quantity) exactly the largest set on which asymptotic stability can be guaranteed for the considered plant, for the given saturation level and uncertainty characteristics.

Unité de Neuropsychologie, Université de Liège (Belgique) Introduction Le trouble d’attention avec hyperactivité (ou ADHD, Attention Deficit/Hyperactivity Disorder) se caractérise par [1] un trouble d’attention, [2] une importante agitation motrice et [3] une impulsivité motrice. Ce trouble présente une prévalence estimée à 5 à 10% de la population prépubère, avec une nette prédominance masculine. Les conséquences de l’ADHD sont importantes : échec scolaire, difficultés d’apprentissages, mauvaise intégration sociale… En neuropsychologie, l’approche de l’ADHD vise à mieux comprendre les difficultés cognitives – et en particulier exécutives – que présentent ces enfants. Ainsi, s’il apparaît qu’un grand nombre de processus exécutifs sont altérés (voir Willcutt et al., 2005), plusieurs auteurs soulignent qu’un déficit de l’inhibition constituerait l’élément-clé qui rendrait compte des manifestations cognitives et cliniques de ce syndrome (Barkley, 1997). De nombreuses recherches ont toutefois suggéré que l’inhibition ne renvoie pas à un processus unitaire mais implique au contraire plusieurs sous-composants (inhibition verbale, motrice, perceptive ; voir par exemple Nassauer & Halperin, 2003). L’objectif de cette étude consiste à déterminer dans quelle mesure les troubles de l’inhibition présentés par les enfants ADHD sont sous-tendus par un déficit généralisé des processus inhibiteurs ou au contraire par une atteinte spécifique d’un de ces processus. Méthode Nous avons administré à 13 enfants ADHD âgé de 6 à 12 ans et 13 enfants de contrôle (appariés sur base de l’âge et du sexe) des tâches d’inhibition évaluant les capacités d’inhibition verbale (test de Stroop), motrice (épreuves de la Statue et du Go/No Go) et perceptive (Nassauer & Halperin, 2003), et une épreuve de raisonnement (Matrices de Raven Colorées). Résultats Les analyses de comparaison de moyennes indiquent que les enfants ADHD présentent des performances inférieures à celles des enfants de contrôle pour l’ensemble des épreuves d’inhibition : inhibition verbale (p<.05), motrice (p<.001) et perceptive (p<.01). Toutefois, des analyses de covariance montrent que lorsque l’on contrôle le niveau de raisonnement, les différences entre nos deux groupes disparaissent pour toutes les tâches, à l’exception de l’épreuve d’inhibition motrice « Statue ». Discussion Ces résultats préliminaires suggèrent que les enfants ADHD ne présentent pas un déficit généralisé des processus inhibiteurs, et que les troubles de l’inhibition motrice constituent probablement un élément-clé caractérisant le profil cognitif de ces enfants. Ces données confirment par ailleurs l’idée selon laquelle le concept d’inhibition recouvre des processus différents susceptibles d’être affectés de façon spécifique dans l’ADHD. [less ▲]

In neuropsychology, inhibition deficits underlie a variety of cognitive and behavioural dysfunctions and are reported in numerous developmental and acquired disorders (such as Attention Deficit and Hyperactivity Disorders–ADHD). Despite a large body of literature regarding inhibition functioning in adult’s neuropsychology, developmental studies on inhibition remained for a long time scarce. Furthermore, most inhibition tools were originally developed for adults and are of limited interest in children – particularly in pre-school children. In this study, we present a new computerized measure of inhibition suitable to young children. This task includes three conditions. The two first conditions assess speed processing and require children to decide quickly, by pressing a response-key, [1] the real size of animals (bird =small) and [2] the on screen size of black rectangles (big or small). The third condition measures inhibition and requires deciding the real size of animals displayed in congruent (big elephant) or incongruent size (big bird) on the screen. Sixty children without neurological disorders and twelve ADHD children aged from 4 to 10 took part in this study. Our aims were to examine the developmental curve of inhibition abilities and to determine the task’s sensitivity in ADHD children. Results show that this task is particularly suitable to preschooler children and provides a good measure of inhibition development (p<.01). Furthermore, this task appears sensitive to inhibition’s disturbances in ADHD children (p<.05). In conclusion, these preliminary results support the validity of this measure to assess inhibition control in young children and its clinical interest in ADHD children. [less ▲]

Il est fréquent de qualifier les « pensées de l’événement » d’anti-dialectiques. Mais c’est, la plupart du temps, pour s’exempter d’une analyse serrée et rigoureuse de la notion d’événement, du corps à corps qu’elle engage avec l’hégélianisme et des enjeux qu’elle recèle. « Anti-dialectique » devient une formule magique qui brouille aussi bien le sens véritable de la dialectique que celui de son « adversaire ». Il s’ensuit une approbation naïve ou une réprobation haineuse de l’usage original du langage que ces « pensées de l’événement » pratiquent. C’est cette pratique que le présent article interroge, à partir d’une rencontre entre Deleuze et Blanchot. Cette rencontre s’articule autour d’un texte de Blanchot auquel renvoie Deleuze dans son Foucault : « Parler, ce n’est pas voir… » (L’Entretien Infini). L’objet majeur de cet article est d’exhiber et d’explorer le point de lutte entre les thèses de « Parler, ce n’est pas voir,… » et la pensée dialectique, constitutif d’une pensée de l’événement. Selon Deleuze, Blanchot y a proposé une approche spécifique de l’événement. Celle-ci consiste, d’une part, à frapper d’inanité toute pensée soumise au régime de la vision, propre à la tradition occidentale. La dialectique hégélienne en serait le point d’acmé. Elle porterait ainsi la vision à l’absolu, en la déliant des bornes constitutives de sa finitude. Il faudra montrer comment la dialectique actualise une puissance que contient déjà toute vision finie, en thématisant la pensée et le langage qui la soutiennent. D’autre part, la détermination de l’événement opérée par Blanchot dans « Parler ce n’est pas voir » consiste à libérer la parole de cette exigence optique pour la porter à sa puissance propre, hors de toute dialectique. La difficulté est alors de comprendre le sens d’une parole qui ne voit pas, sans tomber dans un mysticisme naïf. Ce problème met en jeu le sens même que l’on accorde à la finitude. La finitude propre au régime visuel se révèle n’être que partielle, dans la mesure où elle comporte son propre dépassement vers l’absolu. C’est ce que la dialectique effectue par la prise en compte du lieu et du mode d’énonciation de la finitude elle-même, insoupçonné par celle-ci. Se disant finie, la pensée de la finitude se voit limitée, mais par là voit également l’au-delà de sa limite : elle s’est détachée d’elle-même pour se saisir sous son propre regard. C’est ce qui permet à la dialectique d’englober, dans un discours qui ne cesse de se ressaisir lui-même, ce qui se situe dans la limite ou à l’intérieur du champ de vision, et ce qui se situe au-delà, en dehors de ce champ, parce que cet au-delà est lui-même vu par le discours de la finitude. Un tel mouvement de ressaisie et de totalisation, loin d’être un simple constat d’achèvement du temps ou de l’histoire, est en réalité constitutif de la dialectique entendue comme savoir absolu : savoir hors de toute finitude, in-fini en ce sens qu’il n’a pas de fin. Au contraire, une finitude radicale exige d’être distincte et de la finitude modérée de la vision, et de l’in-fini dialectique qui la porte à l’absolu. Par cette distinction à l’égard de toute récupération dans le régime visuel d’une « totalité en mouvement, finie et illimitée » (EI, 7), Blanchot dégage le sens et le lieu de l’événement : la parole. Car la parole, prise dans son acception la plus tranchante, détachée de tout régime visuel, est un pur mouvement, un pur acte, c’est-à-dire un faire, une praxis. C’est par et dans cette praxis que l’événement est produit. L’événement n’arrive pas, ce n’est pas un objet qui existe et qui advient dans le monde à l’aide d’une bonne parole. L’événement est l’effet de ce faire propre à la parole hors de toute vision. En retour, cette parole n’est pas une activité auto-suffisante, maîtrise intérieure de son propre mouvement : elle est saisie ou affectée radicalement par l’événement, en ce sens qu’elle ne peut se détacher de cet affect pour en faire le tour, considérer sous son regard ce qui lui arrive, en dégager la raison d’être et en ressaisir l’origine. La parole est traversée de part en part par cet affect dont elle ne peut se défaire et provoquée ainsi à entrer en acte. Dans le mouvement même de son processus, la parole affirme sa finitude : sa finitude est ce qui lui arrive et ce dont elle dépend entièrement. C’est en ce sens qu’elle ne voit pas : elle ne voit pas ce qui s’empare d’elle – elle ne le ressaisit pas par devers elle, mais affirme son propre mouvement, sa propre praxis. C’est pourquoi aucun livre de Blanchot n’est théorique : il s’agit au contraire du prolongement d’une pratique de lecture, c’est-à-dire d’un prolongement lui-même pratique, par le mouvement de l’écriture, des affects et des événements qui se sont emparés de ce mouvement lors de la lecture d’Artaud, de Char, de Bataille,… et qui le poussent à se propager. On comprend le champ sémantique déployé par Blanchot dans L’Entretien Infini pour « qualifier » cette parole hors de toute theoria, ou plus exactement pour la faire elle-même par cette qualification : tour, détour, retour, détournement, retournement, tourment,… On en arrive alors à l’exact opposé des poncifs qui circulent sur le langage propre aux « pensées de l’événement », et plus particulièrement sur celui de Maurice Blanchot. Loin d’être un usage mystificateur et incantatoire de notions abstraites (Dehors, Etranger, Neutre, non-rapport, Tout-Autre,…), il apparaît que le langage de Maurice Blanchot est une pure pratique qui saisit son lecteur au moment où il s’y attend le moins, c’est-à-dire quand il ne le voit pas venir. Et l’effet provoqué, à tenir résolument l’entre-deux propre à une finitude radicale, n’est pas de répéter inlassablement les jeux d’oppositions qui structurent notre pensée pour en manifester l’éternelle indécidabilité, mais plutôt de faire le mouvement de lire ou d’écrire, de le finir par conséquent. Ces quelques lignes en sont le témoignage et le prolongement. Le but de cet article est donc de mener le lecteur aux conséquences résolument pratiques d’une pensée rigoureuse de l’événement. Loin de tout intuitionnisme mystique et a-politique, on en arrive ainsi à l’exigence d’un risque politique propre à la pratique langagière de la pensée, pour laquelle faire événement n’est rien d’autre que d’être comptable de sa finitude, c’est-à-dire de son temps.

The aim of this research is to evaluate the through thickness residual stresses distribution in the walls and in the corners of a cold-formed open section made of a material presenting a non linear hardening behaviour. To get results as close as possible to the reality, the complete process is modeled, including coiling and uncoiling of the sheet before the cold bending of the corner itself. The elastic springback after flattening as well as after final shaping are also taken into account. In order to validate the model in predicting the residual stresses distribution, the presented results are confronted to experimental measurements and FE results collected from the literature.

Despite 30 years of international regulations, Hg levels in marine mammals have not decreased. Various environmental models even suggest a rise of mercury in the biota during the next decades, linked to climate change. The objective of this study is (1) to assess Hg levels in blood samples of free-ranging pinnipeds, (2) to understand level variation during different periods of life (gestation, lactation, fasting) and potential impact on lymphocytes using a preliminary in vitro model (peripheral blood mononuclear cells, PBMC). Blood samples were collected from harbour seals (Phoca vitulina n= 22) from the North Sea and from elephant seals from the Californian coast (Mirounga angustirostris 12 females and 12 pups). Harbour seal PBMC were isolated, set in medium culture and contaminated with methyl-Hg (1 µM). Biological tests and proteomic assay were realized on control and contaminated PBMC. Hg levels were from the same order of magnitude for the two species despite two different lifestyles and habitats: from 40 to 590 ng.g-1 fw in harbour seal and from 63 to 919 ng.g-1 fw in elephant seal. Hg concentrations in the blood depend upon several factors such as body weight, fasting and lactation duration for mothers and pups. After 21 days of lactation, female elephant seals doubled their blood Hg levels (from 308 to 593 ng.g-1fw) while a decrease is observed for pups. This increase is linked to mobilization from blubber and muscle during fasting associated to lactation. Cell model revealed an in vitro effect of Hg even at low concentration (1µM). Number of PBMC, viability, metabolic activity, DNA and RNA synthesis were reduced in vitro suggesting deleterious effects of Hg in concentrations encountered in free-ranging pinnipeds. Knowing that Hg methylation in the ocean is linked to temperature, one can wonder on Hg levels (and effects) in pinnipeds during the next decades. [less ▲]

Recent observations revealed an increased abundance of the harbour porpoise in the southern part of the North Sea. Concomitant to sightings of living individuals, the number of stranded porpoises displaying lesions linked to fishing nets has also increased this last decade. The increased abundance of porpoises together with the increase in numbers of bycaught animals raised the question of possible competition between porpoises and fishermen in the North Sea. Therefore, a detailed view on harbour porpoise trophic ecology in this region is crucial for their conservation. Stomachs of the washed ashore porpoises were often empty and provided limited information on their recent diet. Another way of looking into the diet of marine mammals is the analysis of blubber. Stable isotopes ratio (d13C and d15N, SI) and fatty acid composition (20 fatty acids, FA) were analyzed in muscle and blubber of 10 freshly stranded harbour porpoises and in 60 potential prey fish from 10 species collected in the North Sea. The SI ratio and FA composition of these fish enabled a clear classification in different trophic levels and different trophic niches. The FA composition was very similar between harbour porpoise blubber and demersal fish, underlining a preferential predation on that resource for the porpoises investigated. A bias might exist for the porpoises: most of the animals were juveniles, and washed ashore during spring. Porpoises might display other feeding habits in other life stages, other periods of the year. These preliminary results however indicate the enhanced accuracy of crossing these biomarker approaches.

The purpose of the present work is to analyze several aspects related to the connection between the constitutive models, their identification and the FEM predictions. Several issues are addressed: the experimental data base that should be used in the identification procedure, the choice of the mechanical tests involved (monotonous and/or non-proportional loading, homogeneous or heterogeneous tests...), the identification strategies (direct or inverse FE optimization, simultaneous or sequential material parameters identification...). Besides its obvious interest, such study aim to find a good balance between the number and the type of relevant involved mechanical tests in material behavior characterization. This is an important issue for industrial applications. [less ▲]

This paper presents different methods to assess the odour emission and the odour annoyance in the surroundings. It is shown, on the example of landfill areas and composting facilities, that chemical analyses are helpful to identify key compounds of the odour release, and to set up the specification of a monitoring instrument. Sensitive methods, like dynamic olfactometry or sniffing team investigation, are mainly applicable to provide a global odour plume or an average annoyance zone. And the electronic nose can supply a warning signal to the plant manager or a real time estimation of the annoyance zone. [less ▲]

Central Vietnam is composed of two contrasting topographic areas parallel to the coastline: mountains in the West and lowlands in the East where most of the population is concentrated. Sandy soils are largely dominant in the cultivated area in this narrow strip along the sea. Typical constraints of these soils are chemical infertility and acidity, excessive drainage capacity, low organic matter content, associated with particular climate limitations: heavy rain, floods and droughts during certain periods. In the paper, we described a detailed survey among 145 households in villages from the 4 districts of the coastal area of the Thua Thien Hue Province. Existing practices and the socio-economic situation are evaluated and selected pilot farmers are involved in the research of optimal practices. Soil samples (300) and organic matter samples (95) are collected during this survey. The partners of the research include the Hue University of Agriculture and Forestry, the National Institute for Soils and Fertilizers in Vietnam, the Faculty of Agricultural Sciences of Gembloux, and the Catholic University of Louvain in Belgium.

This paper presents the experimental and numerical tests made on the Titanium based alloy Ti6A14V to identify its yield locus and the hardening behaviour. A bi-axial experimental equipment has been used to perform cyclic shear tests, simple shear tests and successive simple shear tests and plane-strain tests. Coupled with classical tensile tests, these tests enable to identify the yield locus and the hardening model. Teodosiu and Hu’s hardening law and isotropic Swift type hardening and kinematic Armstrong Frederick hardening models have been investigated. [less ▲]

In this paper, the first aspect to keep in mind deals with the student-athletes’status. Indeed, the European culture is rather different than the North America’s one. US students, for example, have many advantages to become top athletes. Those who are selected in school, college or university teams are well supported by their institution. The NCCA (National Collegiate Athletic Association) is trying to limit the participation of the freshmen to the university competitions in order to provide them a better teaching context. An overview of the situation of studentathletes in 12 European countries revealed that not all of them have developed a positive climate in favour of their student-athletes. [less ▲]

Le maintien de toutes les tâches constitutives d’une identité et d’un métier d’élève (s’asseoir sur les bancs de l’école, centrer son attention sur le tableau, écouter le professeur, etc.) se prêt mal aux aptitudes requises dans une société de la connaissance. Cette inertie des pratiques scolaires contribuera inévitablement à renforcer l’importance des investissements éducatifs des familles, et les disparités sociales qui les accompagnent.

The objective of this research is to evaluate a Gaussian tilting plume model that takes into account the spray characteristics of agricultural nozzles to predict drift. The application of this type of model has proved to be effective for aerial pollution applications. To be applied successfully to the spray drift, the model has to give accurate predictions of the deposits regarding the spray and material characteristics as well as the weather parameters. To reach this objective, the model parameters must be correctly set based on appropriate theoretical basis and experimental data. Based on wind tunnel measurements, the effect of the most important characteristics of spray droplets from an agricultural nozzle has been modelled using a Gaussian tilting plume approach by discretizing the different droplet classes. Although the theoretical basis of the model is simple, the predicted drift appeared to be in relatively good agreement with the experimental results. The discrepancies could be explained by poor fitting of the dispersion model parameters. Further work is required to optimise the value of the model parameters. [less ▲]

Pregnancy diagnosis is an important part in reproduction management of ruminants. In the last years, a large polymorphic family of placenta-expressed proteins has been discovered in ruminant species and used for pregnancy diagnosis. Members of this family are named pregnancy-associated glycoproteins (PAG), being synthesized in the mono- and binucleate cells of the ruminant’s trophectoderm. Part of them are released in the maternal blood circulation where they can be assayed by different laboratory techniques. Due to large variety of expressed molecules and to large variations in the post-translational processing of the PAG, different immuno-systems present different ability to quantify the PAG released in blood. The sensitivity (92 to 100%) and specificity of PAG radioimmunoassay when used for pregnancy diagnosis are very high. The assay of PAG can also bring very interesting information for researchers working in programs focused on the study of embryonic and fetal mortalities, as well as on embryo biotechnology (ET, FIV, clonage), animal nutrition, or infections diseases resulting in pathologies affecting the pregnancy.

This paper presents a unified thermo-mechanical experimental study on a remoulded unsaturated sandy silt and brings a contribution to the understanding of the fundamental mechanics of unsaturated soils in non-isothermal conditions. The experimental program was carried out at four temperatures and four suction levels using two thermo-hydro-mechanical (THM) cells, one isotropic and the other oedometric. The effect of suction and temperature on the compressibility and on the apparent preconsolidation pressure of the soil is addressed. Finally, an analytical expression of the evolution of the apparent preconsolidation pressure with respect to temperature and suction is proposed. [less ▲]

La fièvre catarrhale ovine (FCO) a été identifiée au Nord de l’Europe le 14 août 2006. L’Allemagne, la Belgique, les Pays-Bas et, dans une moindre mesure, le Grand-Duché de Luxembourg et la France ont été affectés. Le sérotype 8 du virus de la FCO (exotique) a rapidement été identifié ainsi qu’un vecteur, Culicoides dewulfi, une espèce indigène du Nord de l’Europe. La maladie s’est rapidement développée et au 1er février 2007, on recensait 2137 foyers de FCO, toutes espèces de ruminants confondues. Globalement, la maladie a affecté davantage les bovins (54 %) que les ovins (46 %). Les signes cliniques le plus fréquemment observés chez les bovins étaient des lésions sur le museau et la cavité buccale (ulcérations/croûtes), de la salivation et des boiteries chez des animaux adultes. La morbidité et la mortalité animales étaient respectivement de maximum 5 % et 1 %. Les principaux signes cliniques rencontrés chez le mouton étaient également des lésions sur le museau et la cavité buccale (ulcérations/croûtes), de l’amaigrissement et des boiteries. La morbidité et la mortalité animales étaient respectivement de maximum 12 % et 6 %. Les signes cliniques n’étant pas pathognomoniques et le diagnostic différentiel relativement vaste, seul un examen de laboratoire permet de poser un diagnostic de certitude. [less ▲]

The Hilbert-Huang transform (HHT) has been shown to be effective for characterizing a wide range of nonstationary signals in terms of elemental oscillatory components, termed the intrinsic mode functions (IMFs). In this presentation, we describe a combination of methods involving numerical integral transforms and theoretical analysis that cumulate to a new nonparametric method for nonlinear system identification based on multiple slow-fast partitions of the dynamics. This method can find wide applicability to linear and (weakly or strongly) nonlinear systems with various damping and/or stiffness nonlinearities. Moreover, through this method we can systematically examine transient resonance captures in the responses of dynamically interacting nonlinear structures, hence, decomposing and identifying the underlying multimodal nonlinear modal interactions that give rise to complex phenomena.

The electromagnetic interaction between Io and the jovian magnetic field leads to an auroral UV footprint consisting of single or multiple UV spots in both jovian hemi- spheres. According to current theories, the perturbation induced by the motion of Io in the plasma torus propagates along the field lines in the form of Alfvén waves and finally causes electron precipitation in the jovian ionosphere. The occurrence and mul- tiplicity of the secondary spots appear to be related to the position of Io in the plasma torus and have been attributed to partial reflections of the Alfvén waves on the torus boundaries. Nevertheless, the discrepancies between the predicted inter-spot distances and the measurements were found difficult to explain. Additionally, some crucial con- figurations of Io in the torus had never been observed. Our recent HST/ACS observations of the footprint in so far unexplored Io-plasma torus configurations lead to the finding of a new feature in the footprint: a faint spot upstream of the main spot. The observations of this precursor emission, together with the inconsistencies related to the inter-spot distances, suggest a new interpretation of the footprint morphology. We propose that the precursor and the first secondary spot stem from the same mechanism and we interpret them as the counterparts of the main spot occurring in the opposite hemisphere. [less ▲]

A West Florida Shelf (WFS) model is constructed by nesting the Regional Ocean Model System (ROMS) in the Atlantic Hybrid Coordinate Ocean Model (HYCOM) to include both local and deep-ocean forcing, particularly the Gulf of Mexico Loop Current (LC). Hindcast experiments from 2004 to 2006 are presented and compared to observed temperature (moorings and BSOP profiling floats), ADCP velocity time series and HF-Radar surface currents. Two different mixing schemes (Mellor Yamada level 2.5 and K-Profile Parameterization, KPP) are tested and the importance of the vertical resolution for mixing is addressed. The model results of those different configurations are compared to temperature observations on the shelf. Results obtained with the Mellor Yamada scheme are closer to observations during winter (negative buoyancy flux and strong winds) while in summer (positive buoyancy flux and in general weaker wind) the KPP scheme produces more realistic results. Given the present HYCOM configuration we assessed the benefit of nesting ROMS in HYCOM compared to nesting ROMS in climatology. The model solutions on the shelf were compared to various in situ data. The model performed best when using the HYCOM boundary values. Simulated trajectories for drifters deployed off Tampa Bay and Sarasota were used to address the evolution of Karenia brevis concentrations during the 2005 red tide. Near surface drifters were advected offshore, whereas drifters deployed in the bottom Ekman layer matched the subsequently observed Karenia brevis distributions, showing the importance of the 3D structure of coastal ocean currents for red tide on the WFS. As a first attempt at assimilating CODAR surface currents we used an ensemble simulation carried out under different wind forcings to estimate the error covariance of the model state vector and the covariance between the ocean currents and the wind. Improvements were obtained for the modeled currents, not only at the surface, but also at depth. [less ▲]
