New block ILU preconditioner scheme for numerical analysis of very large electromagnetic problems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2002-03-31)
Article
Accés obertLarge electromagnetic scattering and radiation problems are tackled by iterative solvers, which require the use of huge preconditioners. Most often, the incomplete LU decomposition (ILU) of the preconditioner is applied ... -

New results on stabbing segments with a polygon
(2015-01-01)
Article
Accés obertWe consider a natural variation of the concept of stabbing a set of segments with a simple polygon: a segment s is stabbed by a simple polygon P if at least one endpoint of s is contained in P, and a segment set S is stabbed ... -
New subgrid-scale models for large-eddy simulation of Rayleigh-Bénard convection
(Institute of Physics (IOP), 2016)
Text en actes de congrés
Accés obertAt the crossroad between flow topology analysis and the theory of turbulence, a new eddy-viscosity model for Large-eddy simulation has been recently proposed by Trias et al.[PoF, 27, 065103 (2015)]. The S3PQR-model has the ... -

Non-crossing paths with geographic constraints
(Chapman & Hall/CRC, 2019-01-01)
Article
Accés obertA geographic network is a graph whose vertices are restricted to lie in a prescribed region in the plane. In this paper we begin to study the following fundamental problem for geographic networks: can a given geographic ... -
Non-Hermitian coupled semiconductor laser array
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2022)
Text en actes de congrés
Accés obertWe propose and explore a stabilization mechanism of a semiconductor laser array based on asymmetric coupling between neighboring lasers. The stabilization scheme takes advantage of the symmetry breaking of non-Hermitian ... -
Non-regularised inverse finite element analysis for 3D traction force microscopy
(2016-06-10)
Article
Accés obertThe tractions that cells exert on a gel substrate from the observed displacements is an increasingly attractive and valuable information in biomedical experiments. The computation of these tractions requires in general ... -
Nonintrusive parametric solutions in structural dynamics
(2022-02-01)
Article
Accés obertA nonintrusive reduced order method able to solve a parametric modal analysis is proposed in this work. The main objective is being able to efficiently identify how a variation of user-defined parameters affects the dynamic ... -
Nonintrusive reduced order model for parametric solutions of inertia relief problems
(John Wiley & sons, 2021-08-30)
Article
Accés obertThe Inertia Relief (IR) technique is widely used by industry and produces equilibrated loads allowing to analyze unconstrained systems without resorting to the more expensive full dynamic analysis. The main goal of this ... -
Nonintrusive stochastic finite elements for crashworthiness with VPS/Pamcrash
(2020-01-13)
Article
Accés obertCrashworthiness analysis remains an important concern for the design of safety structures. In this context, uncertainties play an essential role in the response of a crash problem with non linear behavior. With this statement ... -
Nonsingular isogeometric boundary element method for stokes flows in 3D
(2014-01)
Article
Accés obertIsogeometric analysis (IGA) is emerging as a technology bridging computer aided geometric design (CAGD), most commonly based on Non-Uniform Rational B-Splines (NURBS) surfaces, and engineering analysis. In finite element ... -
Note on the efficiency of some iterative methods for solving nonlinear equations
(2015-11-02)
Article
Accés obertThe e ciency of algorithms for solving nonlinear equations is a measure of comparison between di erent iterative methods. In the case of scalar equations two parameters are considered as it is well-known, but frequently ... -
