Data assimilation with higher order finite element interpolants
International Journal for Numerical Methods in Fluids, 2022 AbstractThe efficiency of a nudging data assimilation algorithm using higher order finite element interpolating operators is studied. Numerical experiments are presented for the 2D Navier–Stokes equations in three cases: shear flow in an annulus, a forced flow in a disk with an off‐center cavity, and a forced flow in a box all satisfying Dirichlet ...

Pseudo Mapping Method for Singular Integral of Curved Panels [PDF]
한국해양공학회지, 2019 A numerical method is suggested for evaluating the singular integral of curved panels in the higher-order boundary element method. Two-step mapping procedures that are significantly related to the physical properties of singular behaviors were developed ...

A trace finite element method for a class of coupled bulk-interface transport problems [PDF]
, 2014 In this paper we study a system of advection-diffusion equations in a bulk domain coupled to an advection-diffusion equation on an embedded surface. Such systems of coupled partial differential equations arise in, for example, the modeling of transport ...

Glottal Source Contribution to Higher Order Modes in the Finite Element Synthesis of Vowels
Applied Sciences, 2019 Articulatory speech synthesis has long been based on one-dimensional (1D) approaches. They assume plane wave propagation within the vocal tract and disregard higher order modes that typically appear above 5 kHz.

Fractional generalization of memristor and higher order elements [PDF]
Communications in Nonlinear Science and Numerical Simulation, 2013 Abstract Fractional calculus generalizes integer order derivatives and integrals. Memristor systems generalize the notion of electrical elements. Both concepts were shown to model important classes of phenomena. This paper goes a step further by embedding both tools in a generalization considering complex-order objects.

Mechanical Deformation Analysis of a Flexible Finger in Terms of an Improved ANCF Plate Element
Machines, 2022 In recent years, flexible continuum robots have been substantially developed. Absolute nodal coordinates formulation (ANCF) gives a feasible path for simulating the behavior of flexible robots. However, the model of finger-shaped robots is often regarded
