Influences of the compressibility on aerodynamic characteristics of profile under the transonic flow theory

open access: yesVietnam Journal of Mechanics, 2007
Transonic flows are complex problems. At certain Mach numbers, in gas flows there are local transitions from the subsonic into the supersonic and reciprocally, especially the discontinuity throughout shock waves.

Nonclassical shallow water flows [PDF]

open access: yes, 2007
This paper deals with violent discontinuities in shallow water flows with large Froude number $F$. On a horizontal base, the paradigm problem is that of the impact of two fluid layers in situations where the flow can be modelled as two smooth regions ...

Continuity and discontinuity of the debate around fascist art in Toti Scialoja’s critical meditation and in the querelle with Renato Guttuso (1944-1947)

open access: yespiano b, 2018
The essay examines the activity of Toti Scialoja as art critic for the review «Mercurio» between 1944 and 1947, when he proceeds to a precocious analysis of the preceding thirty years, looking for an Italian and international line of painting whit a ...

Element subdivision technique for coupling-matrix-free iterative s-version FEM and investigation of sufficient element subdivision

open access: yesMechanical Engineering Journal, 2016
In s-version finite element method (s-FEM), a local mesh is superposed on a global mesh, and they are solved monolithically. The local mesh represents the local feature such as a hole, whereas the global mesh does the shape of a structure.

A Relaxation result for energies defined on pairs set-function and applications [PDF]

open access: yes, 2007
We consider, in an open subset Ω of RN, energies depending on the perimeter of a subset E С Ω (or some equivalent surface integral) and on a function u which is defined only on E.

Stability of some unilateral free-discontinuity problems in two-dimensional domains

open access: yes, 2002
The purpose of this paper is to study the stability of some unilateral free-discontinuity problems, under perturbations of the discontinuity sets in the Hausdorff metric.Comment: 16 ...

Simplified Excision Techniques for Free Discontinuity Problems in Several Variables

open access: yesJournal of Functional Analysis, 1997
The author studied the free discontinuity problems. These are problems where an unknown discontinuity set can be found by solving a minimization problem. These kind of problems appear in the theory of image segmentation. The author has found applications to problems in several variables thanks to a Sobolev type theorem which ensures the Hölder ...

Fully Covariant Van Dam-Veltman-Zakharov Discontinuity, and Absence Thereof [PDF]

open access: yes, 2002
In both old and recent literature, it has been argued that the celebrated van Dam-Veltman-Zakharov (vDVZ) discontinuity of massive gravity is an artifact due to linearization of the true equations of motion.
