Modelling of Immersive Systems for Collaborative Design

International audienceThis paper proposes to explore the concepts related to immersive situations for collaborative design. The term immersion is investigated depending on the analysis of its constitutive elements, i.e. the actors and the workspace. Based on the feedback of experiments performed in the design process of products, a proposition of categorization of the actors and workspaces gives a conceptual basis for the modelling of immersive systems. An application with educational institutions supports the proposal and aims to prove the efficiency of immersive strategies

Véhicule Inclinable sur Skis, Patins ou Roues Propulsé par Gravité et/ou la Force des Bras

Véhicule sur skis, patins, roues ou chenilles, comportant une structure comprenant un siège et au moins deux skis, inclinable selon un axe horizontal longitudinal, caractérisé en ce qu'il comprend deux skis (ou patins ou roues) latéraux et au moins un ski (patin ou roue) central, et en ce que la structure est conçue de manière que le véhicule, en position inclinée, porte sur le sol par le ski (patin ou roue) central et par un seul ski (patin ou roue) latéral. Les skis latéraux sont montés chacun sur un support articulé sur la structure selon un axe horizontal longitudinal. Lesdits supports latéraux sont reliés à un moyen élastique unique reliant un support latéral à l'autre. La structure forme un siège dont la base est reliée au ski central, et est en matériau moulé. Il est prévu des moyens d'accrochage à un autre véhicule, par l'avant et/ou par l'arrière

Crumpling feasibility of flexible paper sheets. Application to packaging in the food industry

International audienceFlexible packages are considered as the most-reduced form of packaging in terms of environmental performances. In order to contribute to their development, this paper proposes to explore some mechanical properties brought by a new folding process that confers elasticity to flexible materials and consequently new environmental advantages. The innovative folding process consists in sequences of crumpling actions transforming a 2D sheet into a dynamic 3D flexible structure, without cutting or gluing actions. In order to prove the efficiency of the crumpling process, a methodology is proposed to evaluate the ability of a material to be crumpled. The procedure is then applied on different types of papers used in the food industry, and a study case of a crumpled packaging highlights new innovative functionalities as well as its potential environmental gain

Comparative Analysis of Sharing Bike Systems Based on Sustainability Indicators

International audienceWith the growing importance and widely application of the sharing bike system in public transportation systems in cities, many relevant problems emerged, which brought serious influence to the sustainable development of the system. The aim of this paper is first to research the existing sustainability indicators of urban mobility system through literature reviews, next it is to redefine and select the related indicators of sharing bike system through deeply understanding the evolution of bike sharing systems in cities from a sustainable point of view. Then, indicators are selected and applied to better understand the generations of sharing bike systems after the description of the different generations of sharing bike systems. The comparison highlights which characteristics of sharing bike system should be considered to adopt to a sustainable urban development and which features of the sharing bike system could need improvement and change to cater to active demand of the city development

Robust Environmental Evaluation of Industrial Systems

International audienceThe purpose of this paper is to describe a robust environmental evaluation of industrial systems, to help SMEs within their decision making for environmental strategies. The aim is to measure the environmental performance of industrial system based on eco-efficiency concepts within a multi-criteria approach. The environmental evaluation concerns material and energy flows, according to a procedure derived from the well known dependability tool Failure Modes Effects and Criticality Analysis (FMECA). An application to a mechanical industrial process is performed to prove the efficiency of our ecological criticality indicator
