In a lot of industrial contexts, workers may encounter novel situations which have never occured in their training. Yet, such situations must be handeld successfully to prevent high-cost consequences. Such consequences might be human casualties (in high-risk domains), material damages (in manufacturing domains) or productivity loss (in high performance… (More)
Taking human-factors into account in training simulations enables these systems to address issues such as coactivity and management training. However, systems which use virtual reality technologies are usually designed so as to immerse the users in perfectly realistic virtual environment, focusing only on technical gestures and prescribed procedures.… (More)
A combination of heteropolyacids and Ru on carbon catalyzes the conversion of concentrated cellulose feeds into hexitols under H(2) pressure. Quantitative conversion of ball-milled cellulose was observed with remarkable hexitol volume productivity.
The body has a four dimensional structure in space and in time. That is why it can act as an instrument. We imagine an installation in which movements and postures of the hand are translated into sound. However, we thought that it wouldn't be enough for the performer to merely hear the sound of his body: we wanted to provide him a visual trace of his hand… (More)
The hydrolytic hydrogenation of cellulose in the presence of Ru-loaded zeolites and trace amounts of mineral acid shows excellent yields (>90%) for hexitols.
1. Introduction This communication presents and discusses an approach of works' analysis based on activity framework (Daniellou & Rabardel, 2005), elaborated to contribute to a design training process. This approach was developed within the context of a design project aiming to build a Virtual Environment for Professional Training (VEPT) for workers… (More)
