Modeling the origins of adhesive wear across scales
Friction and wear occur at every interface between solid materials.In the design of mechanical devices, it is desirable to be able to quantify and control the amount of friction and wear, as well as predict their evolution with time. ``Tribology'' is the s ...
EPFL2022Improved pivot-slide model of the motion of a curling rock
The pivot-slide model (Shegelski and Lozowski) successfully predicts the slide and curl distances of a curling rock. However, in this model, there is no dependence of the curl distance on the initial velocity, because the ratio between the pivot to sliding ...
CANADIAN SCIENCE PUBLISHING2019The simulation and classification of contact clusters between rough surfaces
The contact area of rough surfaces has a great influence on many mechanical process in tribology. In this report, we used the simulation method to study the contact area between two rough surfaces and its evolution when sliding. We generated artificial sel ...
2019Microscale physico-chemical interactions between hydrodynamically confined liquids and immersed biological surfaces
In contrast to conventional microfluidics, where liquids are typically manipulated within closed channels, open-space microfluidics has emerged as a new class of techniques that are well suited for ver-satile interaction with biological substrates. In part ...
EPFL2019Fractal surfaces in adhesive wear processes.
Jean-François Molinari, Enrico Milanese, Ramin Aghababaei, Tobias Brink
Wear of materials plays a key role in the durability of manifactured objects and it has thus an economical importance in our society. In spite of the efforts, a unified picture of the underlying physics of the phenomenon is still far from being reached, be ...
2018Improving Circuit Mapping Performance Through MIG-based Synthesis for Carry Chains
Giovanni De Micheli, Paolo Ienne, Mathias Soeken, Grace Zgheib, Pierre-Emmanuel Julien Marc Gaillardon, Luca Gaetano Amarù, Xifan Tang, Ana Petkovska, Zhufei Chu
Hard-wired carry chains in FPGAs are designed to improve efficiency of important arithmetic primitives. Although they are proven to be effective for arithmetic-rich functions, there are very few studies on the optimization opportunities of carry chains for ...
ACM2017Generalized Virasoro algebra: left-symmetry and related algebraic and hydrodynamic properties
Motivated by the work of Kupershmidt (J. Nonlin. Math. Phys. 6 (1998), 222 -245) we discuss the occurrence of left symmetry in a generalized Virasoro algebra. The multiplication rule is defined, which is necessary and sufficient for this algebra to be quas ...
Taylor & Francis Ltd2016A Compressible Scaffold for Minimally Invasive Delivery of Large Intact Neuronal Networks
Philippe Renaud, Georg Fantner, Thomas Michael Braschler, Patrick Fraering, Oliver Peric, Amélie Barbara Hildegarde Béduer, Sébastien Mosser, Sidi Ahmed Bencherif
Millimeter to centimeter-sized injectable neural scaffolds based on macroporous cryogels are presented. The polymer-scaffolds are made from alginate and carboxymethyl-cellulose by a novel simple one-pot cryosynthesis. They allow surgical sterility by means ...
Wiley-VCH Verlag2015Molecular dynamics nano-scratching of aluminium: a novel quantitative energy-based analysis method
Jean-François Molinari, Till Junge
Atomistic models for friction suffer from the severe length- and time-scale restrictions of molecular dynamics. Even when they yield good qualitative results, it is difficult to draw meaningful quantitative conclusions from them. In this paper, a novel app ...
Elsevier Science Bv2012Adaptive Control: Algorithms, Analysis and Applications
Adaptive Control (second edition) shows how a desired level of system performance can be maintained automatically and in real time, even when process or disturbance parameters are unknown and variable. It is a coherent exposition of the many aspects of thi ...
