Experimental Study of Sliding Friction Damper for High-Performance Steel Structures

Dimitrios Lignos, Martina Paronesso

Passive energy dissipation devices are widely utilized in buildings to minimize structural and non-structural damage under seismic loading. Commonly used devices include, among others, yield, viscous and friction dampers. While the use of yield dampers, su ...

Multispectral Deep Embeddings As a Countermeasure To Custom Silicone Mask Presentation Attacks

Sébastien Marcel

This work focuses on detecting presentation attacks (PA) mounted using custom silicone masks. Face recognition (FR) systems have been shown to be highly vulnerable to PAs based on such masks [1, 2]. Here we explore the use of multispectral data (color imag ...

Emergence of Cracklike Behavior of Frictional Rupture: The Origin of Stress Drops

Jean-François Molinari, Fabian Barras, Thibault Didier Roch

The process of frictional rupture, i.e., the failure of frictional systems, abounds in the technological and natural world around us, ranging from squealing car brake pads to earthquakes along geological faults. A general framework for understanding and in ...

Adhesive wear mechanisms uncovered by atomistic simulations

Jean-François Molinari, Ramin Aghababaei, Tobias Brink, Lucas Henri Galilée Frérot, Enrico Milanese

In this review, we discuss our recent advances in modeling adhesive wear mechanisms using coarse-grained atomistic simulations. In particular, we present how a model pair potential reveals the transition from ductile shearing of an asperity to the formatio ...

Updated braking forces for the assessment of road bridges

João Miguel De Oliveira Durães Alves Martins

Safety assessments of road bridges to braking events combine the braking force, acting along the longitudinal axis of the deck, with a vertical load that accounts for the vertical component of the traffic action. In modern design standards the vertical loa ...

Study and Simulation of the Energy Balance of an Urban Transportation Network

Alfred Rufer, Philippe Barrade

This paper proposes and studies new strategies for an increase of the energetic efficiency of an urban transportation network fed with catenaries. A simulation tool has been developed to determine the energy efficiency on the global transportation system ( ...
