Linear hyperbolic systems on networks: well-posedness and qualitative properties

Marjeta Kramar Fijavž, Delio Mugnolo, Serge Nicaise

We study hyperbolic systems of one-dimensional partial differential equations under general, possibly non-local boundary conditions. A large class of evolution equations, either on individual 1-dimensional intervals or on general networks, can be reformulated in our rather flexible formalism, which...

An optimal control problem governed by heat equation with nonconvex constraints applied to selective laser melting process

Tonia-Maria Alam, Serge Nicaise, Luc Paquet

This paper deals with a PDE-constraints optimal control problem applied to an Additive Manufacturing process, namely a selective laser melting. Here, we want to control the temperature gradient inside the domain during a fixed time of heating, by acting on the trajectory of the dynamic Gaussian...

Experimental and Numerical Investigations for Quantifying Variability of NR Mechanical Properties after Thermal Aging

Andrés Malo Estepa, Franck Massa, Adnane Boukamel, Thierry Tison, Philippe Champagne, Stéphane Méo, Andreas Wolf

The evolution of mechanical properties of NR with carbon black fillers was examined after a thermal aging step through both experimentation and non-deterministic numerical simulations. A quantification of mechanical properties and associated variability is first proposed for a set of specimens...

Flash point prediction with UNIFAC type models of ethylic biodiesel and binary/ternary mixtures of FAEEs

Débora Costa Do Nascimento, Natália Daniele Dorighello Carareto, Antonio Marinho Barbosa Neto, Vincent Gerbaud, Mariana Conceição da Costa

In order to guarantee safe handling of a combustible liquid, such as biodiesel, it is important to be aware of its Flash Point (FP). Thus, the present study focused on FP experimental measurement and thermodynamic correlation of binary and ternary mixtures of saturated or unsaturated fatty acid...
