Approximations by mini mixed finite element for the Stokes-Darcy coupled problem on curved domains
(Isci-inst Scientific Computing & Information, 2021-03)
In this work we solve a Stokes-Darcy coupled problem in a plane curved domain using curved elements. We approximate the velocity-pressure pair by applying the MINI-element method, for the whole coupled problem. We show ...
Minimal matrices and the corresponding minimal curves on flag manifolds in low dimension
(Elsevier Science Inc, 2009-04)
In general C*-algebras, elements with minimal norm in some equivalence class are introduced and characterized. We study the set of minimal hermitian matrices, in the case where the C*-algebra consists of 3 × 3 complex ...
Natural vibrations of anisotropic plates with an internal curve with hinges
(Pergamon-Elsevier Science Ltd, 2017-01)
The objective of this paper is to propose a general algorithm to obtain approximate analytical solutions for the study of the free vibrations of a rectangular anisotropic thin plate with an internal curved line hinge and ...
Normalization method for J-R curve determination using SENT specimens
(Pergamon-Elsevier Science Ltd, 2018-08)
According to BS 8571:2014, standard J-R curves from SENT geometry can be determined from single or multiple specimens. The recommended methodologies for single specimen include unloading compliance or DCPD, although any ...
An hp finite element adaptive scheme to solve the Poisson problem on curved domains
(Springer, 2015-07)
In this work, we introduce an hp finite element method for two-dimensional Poisson problems on curved domains using curved elements. We obtain a priori error estimates and define a local a posteriori error estimator of ...
Thermal properties of vortices on curved surfaces
(American Physical Society, 2018-01-16)
We use Monte Carlo simulations to study the finite temperature behavior of vortices in the XY model for tangent vector order on curved backgrounds. Contrary to naive expectations, we show that the underlying geometry does ...

Sensitivity analysis in optimized parametric curve fitting
(EMERALD GROUP PUBLISHING LIMITED, 2015-03-02)
Purpose-Curve fitting from unordered noisy point samples is needed for surface reconstruction in many applications. In the literature, several approaches have been proposed to solve this problem. However, previous works ...
