Or, si aujourd’hui, il est aisé d’identifier des états de référence, quant aux propriétés des matériaux et des ouvrages tant sur le plan physique, chimique, mécanique…, la mise en évidence de ces états de références s’avère délicate pour les structures et formulations anciennes. L’objectif de cet article est d’étudier la durabilité des réseaux d’assainissement de la ville de Rennes (France) constitués de conduites à base cimentaire. Des données relatives aux caractéristiques des conduites ont été collectées (type du réseau, diamètre, épaisseur, date de mise en place…) pour chaque tronçon étudié. En plus de la qualité apparente des prélèvements, des essais de caractérisation ont été réalisés sur des éprouvettes cylindriques carottées tels que la masse volumique, la porosité et la résistance ultime en compression. Les résultats des analyses sont recensés et discutés et des corrélations sont établies pour expliquer l’évolution des propriétés des matériaux et évaluer la cinétique d’altération. Cette investigation est réalisée dans l’optique de pouvoir envisager les opérations de maintenance dans une logique de prévention et non consécutive à un accident.","PeriodicalId":43816,"journal":{"name":"Materiaux & Techniques","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44074077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For these reasons, the use of the artificial vision in the world of quality control has become more than necessary. However, these images are often large in terms of quantity and size, which becomes a problem in quality control centers, where engineers are unable to store these images. For this, efficient compression techniques are necessary for archiving and transmitting the images. The reduction in file size allows more images to be stored in a disk or memory space. The present paper proposes an effective technique for redundancy extraction using the Principal Component Analysis (PCA) approach. Furthermore, it aims to study the effects of the number of eigenvectors employed in the PCA compression technique on the quality of the compressed image. The results revealed that using only 25% of the eigenvectors provide very similar compressed images compared to the original ones, in terms of quality. These images are characterized by high compression ratios and a small storage space.","PeriodicalId":43816,"journal":{"name":"Materiaux & Techniques","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41622094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

L’économie circulaire pousse de plus en plus à intégrer des déchets dans les chaînes de production. Ce travail analyse la possibilité d’intégration de déchets urbains tel que des résidus fins de boues sédimentaires de dragage (BSD) pour partiellement remplacer la terre crue dans la production de briques en terre crue comprimée (BTCC). Les BSD ont été caractérisées par diffraction des rayons X, fluorescence X et analyse thermique. La présence de métaux lourds et composés organiques polluants a été quantifiée. Des pastilles de différentes teneurs en eau et compositions (mixte BSD et terres crues) ont été réalisées. Leur tenue à l’abrasion a été étudiée sur l’essai standardisé du pion-disque. Les pastilles contenant de la BSD dont les organiques ont été éliminés thermiquement, ont une faible tenue à l’abrasion. Cette performance est améliorée par l’ajout de 5 % de ciment, qui permet d’augmenter la cohésion du matériau.","PeriodicalId":43816,"journal":{"name":"Materiaux & Techniques","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"57959334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Remanufacturing may involve adding new and better functionality to used products, such as adding more wear-resistant materials to the surface or new sensor systems. Remanufacturing has been undertaken for products such as: automobile parts, machinery, photocopiers, single-use cameras, furniture, and turbine components, etc. It is generally superior to material recycling in terms of energy and material savings. Our project aims to develop technologies necessary for the promotion of remanufacturing and to establish a cooperative network related to remanufacturing. As technical development items, our aim is to develop methods to assess the reliability of parts/components, develop technologies to restore deteriorated metal surfaces of used products, introduce production management methods for remanufacturing, and design a circulation system to retain the added values of products. In this paper, we introduce an outline of the project and present some preliminary results. This paper shows the possibility to quantitatively evaluate the carbide distribution (size and density) of the carburized surface of a gear, and also shows the potential to repair materials exposed to a high-temperature oxidative atmosphere by Pr-Ir coating technology.","PeriodicalId":43816,"journal":{"name":"Materiaux & Techniques","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"57959531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This special issue ofMatériaux et Techniques collects 9 papers presented during this meeting. These papers can be regarded as highlights of the conference, in as far as they deal with some of the main topics that were discussed during these two days. SAM conferences are dedicated to the exploration of the interdisciplinary boundaries related to materials and their connection with society, the environment and nature. They try to analyze how anthroposphere, biosphere and geosphere interact. They propose new approaches, new methodologies and act as a laboratory for new thinking in the area. One boundary between the spheres is related to Materials and Social Sciences and Humanities (SSH): – the paper by Jean-Pierre Birat explores the matter of environmental ethics, which is the contribution of ethics and philosophy for fleshing out the concepts of sustainable development, which the material community has adopted wholeheartedly, of the circular economy, of the responsibilities for pollution, of the nature of pollution, etc. [1]; – Michael Kohlgrüber et al. [2] discuss the topic of social innovation and show how impowering the future users of a new technology in the workplace to engage in process innovation accelerates its implementation and its timeto-market. It also speeds up the Social Life-Cycle of that particular innovation (the concept is defined in the previous paper).","PeriodicalId":43816,"journal":{"name":"Materiaux & Techniques","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"57959277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
