Analysis of the influence of interpolation algorithm on the numerical simulation results of transmission boundary

地震科学进展
The distance traveled by contour wave with artificial wave velocity in a step-time is often inconsistent with the mesh size. Therefore, when the transmission boundary formula is applied, the calculation nodes of transmission boundary are usually ...

A new interpolation method based on satellite physical character in using IGS precise ephemeris

Geodesy and Geodynamics, 2014
Due to the deficiency of sliding Lagrange polynomial interpolation, the author proposes a new interpolation method, which considers the physical character of satellite movement in coordinate transformation and reasonable selection of interpolation ...

Convergence of Integro Quartic and Sextic B-Spline interpolation [PDF]

Sahand Communications in Mathematical Analysis, 2018
In this paper, quadratic and sextic B-splines are used to construct an approximating function based on the integral values instead of the function values at the knots.

Continued Fraction Interpolation of Preserving Horizontal Asymptote

Journal of Mathematics, 2022
The classical Thiele-type continued fraction interpolation is an important method of rational interpolation. However, the rational interpolation based on the classical Thiele-type continued fractions cannot maintain the horizontal asymptote when the ...

Topology Optimization of Geometrically Nonlinear Structures Based on a Self-Adaptive Material Interpolation Scheme

Machines, 2023
In this paper, a simple and effective self-adaptive material interpolation scheme is proposed to solve the numerical instability problem, which may occur in topology optimization considering geometrical nonlinearity when using density-based method.

An extended finite element method with smooth nodal stress [PDF]

, 2013
The enrichment formulation of double-interpolation finite element method (DFEM) is developed in this paper. DFEM is first proposed by Zheng \emph{et al} (2011) and it requires two stages of interpolation to construct the trial function.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Impact of the floating-point precision and interpolation scheme on the results of DNS of turbulence by pseudo-spectral codes

, 2007
In this paper we investigate the impact of the floating-point precision and interpolation scheme on the results of direct numerical simulations (DNS) of turbulence by pseudo-spectral codes. Three different types of floating-point precision configurations

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

A new multiplier for Lagrange interpolation in constrained non linear optimization [PDF]

المجلة العراقية للعلوم الاحصائية, 2010
In this paper, we have investigated a new multiplier for the Lagrange interpolation by modifying the initial value of the multiplier in order to reduce the errors and avoid the use of arbitrary values for the initial .
