On the Behavior of Two C1 Finite Elements Versus Anisotropic Diffusion

International Journal for Numerical Methods in Fluids, EarlyView.
Bi‐cubic Hemite‐Bézier and reduced cubic Hsieh‐Clough‐Tocher finite elements, of class C1, are compared for the solution of a highly anisotropic diffusion equation. They are tested numerically for various ratios of the diffusion coefficients on different meshes, even aligned with the anisotropy.

Accuracy of genomic BLUP when considering a genomic relationship matrix based on the number of the largest eigenvalues: a simulation study

Genetics Selection Evolution, 2019
Background The dimensionality of genomic information is limited by the number of independent chromosome segments (M e ), which is a function of the effective population size.

Incremental Model Order Reduction of Smoothed‐Particle Hydrodynamic Simulations

International Journal for Numerical Methods in Fluids, EarlyView.
The paper presents the development of an incremental singular value decomposition strategy for compressing time‐dependent particle simulation results, addressing gaps in the data matrices caused by temporally inactive particles. The approach reduces memory requirements by about 90%, increases the computational effort by about 10%, and preserves the ...

Perspective Projection of an Ellipse and an Ellipsoid for Analytical View Factor Evaluation

Heat Transfer, EarlyView.
ABSTRACT Radiative view factors are fundamental quantities for evaluating radiative heat transfer between different surfaces. While analytical expressions of view factors have been evaluated for various types of basic geometries, including circular disks and spheres, extending these solutions to more complex geometries, such as ellipses and ellipsoids ...

The affine equivariant sign covariance matrix: asymptotic behavior and efficiencies. [PDF]

We consider the affine equivariant sign covariance matrix (SCM) introduced by Visuri et al. (J. Statist. Plann. Inference 91 (2000) 557). The population SCM is shown to be proportional to the inverse of the regular covariance matrix. The eigenvectors and

Second‐Law Analysis of Mini/Micro Counterflow Parallel‐Plate Heat Exchangers: Optimizing Effectiveness by Minimizing Wall Entropy Production

Heat Transfer, EarlyView.
ABSTRACT We present an analytical and numerical study of the entropy production rate in laminar counterflow parallel‐plate heat exchangers, aiming to investigate the interplay between multidimensional wall conduction, entropy production, and the optimum wall conductivity that leads to maximum effectiveness.
