Interoperability Between PLM and RoHS Compliance Management Based on XML and Smart Client

Abstract: Nowadays, more and more companies are going to adapt themselves to restriction on the use of certain hazardous substances (RoHS) compliance and enforcement by leveraging product lifecycle management (PLM) technology. The paper presents a general framework that integrates the bill of material extensible markup language (XML) files from heterogeneous PLM systems to RoHS compliance management system. This framework is based on the use of Smart Client technology to obtain flexibility required for complex and distributed environments. It also makes use of XML technology and data structure to obtain reuse and robustness.

Effets d’un bioadjuvant sur les caractéristiques de surface de pâtes cimentaires

Abstract: L’objectif de cet article est d’etudier l’influence d’un bioadjuvant (BA) sur les caracteristiques de surface des pâtes cimentaires. Les caracteristiques de surface des pâtes de ciment bioadjuvantees sont etudiees avec la mesure de l’angle de contact dynamique. Ces essais ont ete realises pour comparer le comportement de pâtes cimentaires seches avec 1,5 % de BA et sans bioadjuvant lorsqu’une goutte d’eau est deposee sur leur surface. Les resultats montrent que le bioadjuvant diminue les vitesses d’evolution des angles de contact. Une technique originale d’analyse de la penetration par rapport a l’etalement s’affranchissant du parametre temps a ete developpee. Elle a permis de mettre en evidence que le bioadjuvant favorise l’etalement de la goutte et diminue le phenomene de penetration au sein du materiau.

Characterisation of beech wood pulp towards sustainable rapid prototyping

Abstract: Wood has several advantages that are transferable to various derivates allowing the introduction of a sustainable material into the product lifecycle. The objective of this paper is to apply a design for manufacturing approach based on wood flour rapid prototyping, while associating the requirements of the 'mass customisation' in the implementation of a customised product. New collaborative software allows consumers to be involved in the design process. Prototyping processes allow direct manufacturing of products.

Solid Oxide Electrolysis Cell Analysis by Means of Electrochemical Impedance Spectroscopy: A Review

Abstract: High temperature water electrolysis based on Solid Oxide Electrolysis Cell (SOEC) is a very promising solution to produce directly pure hydrogen. However, degradation issues occurring during operation still represent a scientific and technological barrier in view of its development at an industrial scale. Electrochemical Impedance Spectroscopy (EIS) is a powerful in-situ fundamental tool adapted to the study of SOEC systems. Hence, after a quick presentation of EIS principle and data analysis methods, this review demonstrates how EIS can be used: (i) to characterize the performance and mechanisms of SOEC electrodes; (ii) as a complementary tool to study SOEC degradation processes for different cell configurations, in addition to post-test tools such as scanning electron microscopy (SEM) or X-ray diffraction (XRD). The use of EIS to establish a systematic SOEC analysis is introduced as well.
