Homotopy perturbation technique for improving solutions of large quadratic eigenvalue problems: Application to friction-induced vibration

Jérémy Sadet, Franck Massa, Thierry Tison, Isabelle Turpin, Bertrand Lallemand, El-Ghazali Talbi

This paper puts forward a projection technique for accurately calculating solutions of large Quadratic Eigenvalue Problem. The aim here is to stabilize the complex eigensolutions whilst reducing residual errors, especially when considering significant damping contribution or asymmetric stiffness…

Facile synthesis of fluorine-free, hydrophobic, and highly transparent coatings for self-cleaning applications

Abderrahmane Hamdi, Julie Chalon, Pascal Laurent, Benoit Dodin, El Hadj Dogheche, Philippe Champagne

Non-fluorinated coatings have recently emerged as a new approach to avoid contamination on transparent surfaces. This research work concerns the synthesis of highly transparent, hydrophobic, durable, and self-cleaning coatings as an alternative to fluorine-based coatings used on glass. The…

Hybrid additive/subtractive manufacturing system to prepare dense and complicated ceramic parts

Anne Leriche, Enrique Juste, Qirong Chen, Marie Lasgorceix, Fabrice Petit

As the conventional binder jetting method is limited in terms of achievable density and finish surface, a new concept of hybrid subtractive/additive manufacturing system has been recently developed. The system relies on a modified binder jetting machine which integrates a slurry-based deposition…

Fabrication of higher thermal stability doped β-tricalcium phosphate bioceramics by robocasting

Nicolas Somers, Florian Jean, Marie Lasgorceix, Anthony Thuault, Fabrice Petit, Anne Leriche

β-tricalcium phosphate (β-TCP) is one of the most attractive biomaterials for bone repair since it shows an excellent biological compatibility, osteoconductivity, and resorbability. It can be used to produce bone implants serving as temporary supports for bone regeneration.However, there are still…

Weighted $$L^2$$ Version of Mergelyan and Carleman Approximation

Séverine Biard, John Erik Fornæss, Jujie Wu

Abstract We study the density of polynomials in H2 ( E , φ ) , the space of square integrable functions with respect to e−φdm and holomorphic on the interior of E in C, where φ is a subharmonic function and d m is a measure on E . We give a result where E is the union of a Lipschitz graph and a…

On the nonexistence and rigidity for hypersurfaces of the homogeneous nearly Kähler S3×S3

Zejun Hu, Marilena Moruz, Luc Vrancken, Zeke Yao

In this paper, we study hypersurfaces of the homogeneous NK (nearly Kähler) manifold S3×S3. As the main results, we first show that the homogeneous NK S3×S3 admits neither locally conformally flat hypersurfaces nor Einstein Hopf hypersurfaces. Then, we establish a Simons type integral inequality…

Equation cohomologique d'un automorphisme affine hyperbolique du tore

Abdellatif Zeggar

We study the discrete cohomological equation of a hyperbolic affine automorphism Y of the torus (whose linear part is not necessarily diagonalisable). More precisely ; if d is the cobord operator defined by : d (h) = h-hoY for every element h of the Fréchet space E of the differentiable functions…
