Les outils agricoles dans la Chine du XIVe siècle d'après le Nongshu de Wang Zhen
No full textOlivier Guyonvarch : Agricultural Tools in Fourteenth-Century China in the Light of Wang Zhen 's Nongshu.
This paper is a partial and annotated translation of the chapters (juan ) describing agricultural tools in the Agricultural Treatise of Wang Zhen. This study is not philological or litterary, but resolutely technical. The author is dealing with agronomical relevance of the text, compared with present knowledge. The tools that axe chosen are the most representative and of the most interest for non-specialist readers : the plow for plowing ; hoes, harrows, and rolls to prepare the seed-bed ; the drill ; small hoes and rakes for weeding ; knifes, scythes, and cradle-scythes for harvesting. Readers have thus an access to the technical environment of the Chinese peasant In other respect, the text presents clearly the specialization of the tools and die way of using them, according as they are used in dry farming or in irrigated paddy-fields.Cet article est une traduction partielle et commentée des chapitres (juan ) regrou¬ pant les outils aratoires dans le Traité agricole de Wang Zhen (xive siècle). L'approche n'est pas philologique ni littéraire, mais résolument technique. L'au¬ teur s'intéresse à la pertinence du texte du point de vue de l'agronomie et au regard des connaissances actuelles. Les outils retenus ici sont les plus représen¬ tatifs et les plus intéressants pour le lecteur non-spécialiste : la charrue, pour le labour ; les houes, herses et rouleaux, pour la préparation du lit de semences ; le semoir ; les houes et râteaux, pour le désherbage ; les couteaux, faucilles et faux armées, pour la récolte. Leur description donne ainsi accès à l'univers technique du paysan chinois. Par ailleurs, le texte nous éclaire sur la spécialisation de l'outillage et sur ses modes d'utilisation selon qu'on se trouve en zone de culture sèche ou en zone de rizière inondéeGuyonvarch Olivier.

A parallel implementation of the modified augmented Lagrangian preconditioner for the incompressible Navier-Stokes equations
Full text linkWe describe a parallel implementation of a block triangular preconditioner based on the modified augmented Lagrangian approach to the steady incompressible Navier-Stokes equations. The equations are linearized by Picard iteration and discretized with various finite element and finite difference schemes on two- and three-dimensional domains. We report strong scalability results for up to 64 cores. © 2012 Springer Science+Business Media New York
Stress analysis and fracture simulation of aluminosilicate glass plates under Ring-On-Ring loading
Full text linkRing-On-Ring (ROR) tests have been widely applied to evaluate the biaxial flexural strength of brittle materials. Properly designed geometry of specimens and loading configurations are essential for accurate test results. In this paper, the stress distribution of round glass plates subjected to loading between concentric rings was investigated via finite element analysis. In particular, the effects of the ratio of the ring diameter, overhang and thickness of plates were studied and discussed. ROR tests on aluminosilicate glass were then conducted together with numerical simulations based on the smeared fixed crack method. The out-of-plane deformation of glass plates can be reproduced well by the numerical model. In order to mimic the observed fracture modes, numerical models with different mesh geometries were utilized and compared. Unstructured quadrilateral mesh and triangular mesh types were proven to be efficient in reproducing the fracture and failure morphology of glass specimens
Deviation from the recommended schedule: optimal dosing interval for a two-dose vaccination programme
No full text<p>Optimal dosing interval:</p>
<p>Program in matlab associated with paper "Deviation from the recommended schedule: Optimal dosing interval for a two-dose vacciantion programme".</p>
<p>Model details: A delay-differential model to describe the dynamics of disease spread with a two-dose vaccination. The model incorporated variables such as waning vaccine-induced and naturally-acquired immunity, as well as the capacity for vaccine distribution. We simulated the model and determined the optimal dosing interval as a function of vaccien efficacy against infection and outcomes by comparing the disease burden in delayed vaccination scenarios to that of following the recommended schedule.</p>
