Analysis of a quasi-variational contact problem arising in thermoelasticity [PDF]
, 2020 We formulate and study two mathematical models of a thermoforming process involving a membrane and a mould as implicit obstacle problems. In particular, the membrane-mould coupling is determined by the thermal displacement of the mould that depends in ...

Dynamic network analysis of contact diaries [PDF]
Social Networks, 2021 Analyzing two-mode networks linking actors to events they attend may help to uncover the structure and evolution of social networks. This classic social network insight is particularly valuable in the analysis of data extracted from contact diaries where contact events produce — and at the same time are the product of relations among participants ...
