Flooding is a dominant risk in the Algerian territory. It often appears when streams overflow, when they are dry all the year (the wadis) in the agricultural plains. However, in the last decades, they are appearing more frequently in urban areas, causing human and material losses. In order to define the areas that could be flooded, locate recurrent events and identify their reasons, the preliminary historical study of floods in urban areas was developed. [less ▲]

Damage caused by ungulates to agricultural areas are difficult to evaluate because the real extent of the damage remains usually poorly described and potentially arising conflicts. Recent advances in unmanned aerial system (UAS) provide new versatile mapping and quantification possibilities in a wide range of applications. We used crop fields (Zea mays) damaged by wild boar (Sus scrofa) and compared the extent of the damage by means of three methods: i) traditional ground-based assessment ii) UAS orthoimages with operator delineation and iii) UAS Crop Height Model with automatic delineation based on height threshold. We showed for the first time that UAS could be applied for assessing damage of ungulates to agriculture. The two methods using UAS imagery provide coherent and satisfactory results and trended to underestimate the damage area when compared to in-use ground-based field expertise. However we suggest that performance of UAS should further be tested in variable conditions in order to assess the broad application of this tool. Our study describes the potential of UAS as a tool for estimating more accurately the damage area and subsequently the compensation costs for wildlife damage. The proposed approach can come in support of local and regional policies for the definitions of compensation for farmers. [less ▲]

As well known, in the analysis of bird impact events the bird is often reduced, even experimentally, to a surrogate projectile modeled as a weakly compressible fluid (typically a mixture of water and air). From a numerical standpoint, the presence of a free surface and the strong interaction with the aircraft structures represent a limit for traditional computational fluid dynamics methods based on an Eulerian grid. On the other hand, classical Lagrangian methods cannot cope with the extremely large deformations experienced by the projectile during the impact. The Particle Finite Element Method (PFEM) is a Lagrangian particle method that can account for very large deformations, preserving the robustness and generality of the finite element method, and thus owning a key advantage over other approaches, e.g. Smoothed Particle Hydrodynamics (SPH), usually cursed with consistency and stability issues. To assess the possibilities of the method in the context of bird impact, theoretical analyses are initially performed based on the impact of a water jet on a rigid surface. Then, the influence of the geometry of a more realistic projectile is analyzed and the capability of the method to take into account separation and fragmentation is highlighted. [less ▲]

Parathyroid hormone (PTH) measurement in serum or plasma is a necessary tool for the exploration of calcium/phosphate disorders, and is widely used as a surrogate marker to assess skeletal and mineral disorders associated with chronic kidney disease (CKD), referred to as CKD-bone mineral disorders (CKD-MBD). CKD currently affects >10% of the adult population in the United States and represents a major health issue worldwide. Disturbances in mineral metabolism and fractures in CKD patients are associated with increased morbidity and mortality. Appropriate identification and management of CKD-MBD is therefore critical to improving clinical outcome. Recent increases in understanding of the complex pathophysiology of CKD, which involves calcium, phosphate and magnesium balance, and is also influenced by vitamin D status and fibroblast growth factor (FGF)-23 production, should facilitate such improvement. Development of evidence-based recommendations about how best to use PTH is limited by considerable method-related variation in results, of up to 5-fold, as well as by lack of clarity about which PTH metabolites these methods recognise. This makes it difficult to compare PTH results from different studies and to develop common reference intervals and/or decision levels for treatment. The implications of these method-related differences for current clinical practice are reviewed here. Work being undertaken by the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) to improve the comparability of PTH measurements worldwide is also described. [less ▲]

This paper describes the development of a complete methodology for the aeroservoelastic modeling of horizontal axis wind turbines at the conceptual design stage. The methodology is based on the implementation of unsteady aerodynamic modeling, advanced description of the control system and nonlinear finite element calculations in the SWT wind turbine design package. The aerodynamic modeling is carried out by means of fast techniques, such as the Blade Element Method and the unsteady Vortex Lattice Method, including a free wake model. The complete model also includes a description of a doubly fed induction generator and its control system for variable speed operation. The SWT software features a non-linear finite element solver with multi-body dynamics capability. The full methodology is used to perform complete aeroservoelastic simulations of a realistic 2MW wind turbine model. The interaction between the three components of the approach is carefully analyzed and presented here. [less ▲]

On connaît la façon dont l’histoire littéraire a narré la geste de la bohème fin de siècle en favorisant les dialogues et recoupements entre les différents groupuscules potaches qui ont émaillé le Paris de l’époque. Pourtant, il y a, dans le même temps, des différences patentes entre les Déliquescences du pseudo-décadent Adoré Floupette (1885) et les signataires de l’Album zutique, confectionné en 1871 mais non-destiné à la publication, de la même façon que les articles du Chat Noir ne répondent pas aux mêmes objectifs que ceux publiés dans les colonnes de L’Hydropathe (1879-1880). L’Hydropathe et Le Chat Noir ont par ailleurs en commun un statut s’apparentant à celui d’une caisse de résonnance : tous deux se construisent dans le prolongement d’un lieu de sociabilité qui les précède et dont ils relatent les spécificités. Société tapageuse plus ou moins organisée d’un côté, cabaret bigarré de l’autre, les espaces pivots à l’origine de ces journaux orientent les préoccupations de ces derniers et peuvent sembler limiter leur marge de manœuvre. La comparaison des logiques de présentation de soi et de réclame permet pourtant d’observer certaines divergences entre les moyens mobilisés par ces deux organes à la fois pour affirmer leur singularité et pour exposer les collectifs qui les élaborent.

Chacun d’entre nous se caractérise par une manière d’appréhender la réalité qui se traduit, souvent de manière inconsciente, dans la façon dont il parle. Celle-ci révèle ses modes de raisonnement et détermine pour bonne partie son action. Ce principe est valable tant pour un individu que pour un groupe familial, social, politique, … La Mise au carré, qui constitue l’objet principal de ce livre, est autant un outil de compréhension du langage et de la pensée que de génération de nouvelles idées. Ses visées se situent donc à la fois dans l’analyse et la créativité. Par son système de visualisation qui le rend utilisable en de nombreuses circonstances, il permet à tout un chacun de saisir les idées clés d’un discours, celles-ci étant fondées sur des associations ou des oppositions entre plusieurs éléments. Ce faisant, il met également en évidence les implicites de ce discours. Au delà de cette intention d’analyse, il offre aussi des possibilités remettre en question ces implicites et ouvre vers de nouvelles manières de penser et donc d’agir. La Mise au carré est applicable à tout type de propos : discours individuel, programme politique, publicité, conversation, … Elle conviendra particulièrement aux professionnels pour lesquels le développement de la pensée et de l’action sont le cœur de métier : enseignants, formateurs, psychologues, consultants, analystes politiques, chercheur,… Il s’adresse également à toute personne désireuse d’améliorer sa capacité à communiquer à autrui. Enfin, la prise de recul que permet cet outil permettra le déploiement de nouvelles idées de tout un chacun. L’outil de Mise au carré est soutenu par deux autres techniques qui viennent l’enrichir. La première, dénommée Mie en évidence des liaisons, renforce son pôle « analyse ». La seconde, dénommée Mise en matrice de découverte, facilite la création de nouvelles idées et renforce donc le pôle « créativité ». Cet outil sera particulièrement apprécié lorsqu’il s’agira de : - mieux comprendre le raisonnement d’une personne ou d’un groupe ; - contester un point de vue et proposer des alternatives ; - améliorer son action ou celle d’autrui ; - (aider à) prendre des décisions ; - faciliter la médiation de points de vue opposés.

In this letter, we show how a simple motion-guided nonlinear filter can drastically improve the accuracy of several pedestrian detectors. More specifically, we address the problem of how to pre-filter an image so almost any pedestrian detector will see its false detection rate decrease. First, we roughly identify moving pixels by cumulating their temporal gradient into a motion history image (MHI). The MHI is then used in conjunction with a nonlinear filter to filter out background details while leaving untouched foreground moving objects. We also show how a feedback loop as well as a merging procedure between the filtered and the unfiltered frames can further improve results. We tested our method on 26 videos from 6 categories. The results show that for a given miss rate, filtering out background details reduces the false detection rate by a factor of up to 69.6 times. Our method is simple, computationally light, and can be implemented with any pedestrian detector. Code is made publicly available at: https://bitbucket.org/wany1601/pedestriandetection. [less ▲]

Insects often rely on olfaction to communicate with surrounding conspecifics. While the chemical language of insects has been deciphered in recent decades, few studies have assessed how changes in atmospheric greenhouse gas concentrations will impact pheromonal communication by insects. Here, we hypothesize that changes in the concentration of atmospheric carbon dioxide (CO2) affect the whole dynamics of alarm signaling in aphids, including: (1) the production of the active compound (E)-β-farnesene (Eβf), (2) emission behavior when under attack, (3) perception by the olfactory apparatus, and (4) the escape response. We reared two strains of the pea aphid Acyrthosiphon pisum under ambient and elevated CO2 concentrations for several generations. We found that an increase in CO2 concentration reduced the production (i.e., individual content) and emission of Eβf (released under predation events). While no difference in Eβf neuronal perception was observed, we found that an increase in CO2 strongly reduces the escape behavior expressed by an aphid colony following exposure to natural doses of the alarm pheromone. In conclusion, our results confirm that changes to greenhouse gases do impact chemical communication in insects, and could potentially have a cascade effect on interactions with higher trophic levels.
