Les cinématiques parallèles se caractérisent par une structure à plusieurs chaînes cinématiques reliant la base à l’organe terminal. Les déplacements des moteurs sont couplés, ce qui accroît la complexité du calibrage de ces structures. Ce papier présente ...
Lead oxide based ferroelectrics, represented by lead zirconate titanate (Pb(Zr,Ti)O-3) or PZT) are the most widely used materials for piezoelectric actuators, sensors and transducers due to their excellent piezoelectric properties. Considering lead toxicit ...
Visual modeling languages propose specialized diagrams to represent behaviour and concepts necessary to specify IT systems. As a result, to understand a specification, the modeller needs to analyze these two types of diagrams and, often, additional stateme ...
Within the EFDA technology program, CRPP designed and prepared a short length of full size Nb3Sn developmental conductor to be tested in the SULTAN test facility. Nb3Sn strand with a higher specification and low Cu:non-Cu ratio was supplied by Outokumpu. H ...
The influence of both early and late heat treatments on the microstructure and on the hydration products of Portland cement mortars has been investigated. The mortars were given either a 4-h or 28-day precure at 20 °C before heating at 90 °C for 12 h and w ...
Some cementitious materials cured at elevated temperature may expand on subsequent exposure to moisture. Concern has been expressed as to the relevance of small laboratory specimens to field concretes, in particular due to the potential leaching of ions in ...
Interactive systems, games, VR and multimedia systems require more and more flexible Virtual Humans with individualities. Behavioral animation seems to be the best way to develop this kind of applications, but there is still a major problem to select the r ...
We demonstrate theoretically and experimentally a new multiplexing method for volume holographic storage using a single reference beam that is composed of multiple plane waves or is a spherical wave. We multiplex the holograms by shifting the recording mat ...
