Enriched isogeometric collocation for two-dimensional time-harmonic acoustics
(Elsevier, 2020)
In this work, the isogeometric collocation (IGA-C) is paired with two types of enrichment: Plane Wave (PW-) and Generalized Harmonic Polynomial (GHP-) functions, to solve 2D-problems for the Helmholtz equation. A parametric ...
On the numerical stability and mass-lumping schemes for explicit enriched meshfree methods
(2012-02-24)
Meshfree methods (MMs) such as the element free Galerkin (EFG)method have gained popularity because of some advantages over other numerical methods such as the finite element method (FEM). A group of problems that have ...
An enrichment scheme for solidification problems
(Springer, 2013-06)
A new enriched finite element formulation for solving isothermal phase change problems is presented. We propose a fixed mesh method, where the discontinuity in the temperature gradient is represented by enriching the finite ...
A hybrid-Trefftz formulation for plane elasticity with selective enrichment of the approximations
(WILEY-BLACKWELL, 2011)
This work is related to the so-called non-conventional finite element formulations. Essentially, a methodology for the enrichment of the initial approximation which is typical of the meshless methods and based on the clouds ...
RANDOM-SET METHODS IDENTIFY DISTINCT ASPECTS OF THE ENRICHMENT SIGNAL IN GENE-SET ANALYSIS
(INST MATHEMATICAL STATISTICS, 2007)
A prespecified set of genes may be enriched, to varying degrees, for genes that have altered expression levels relative to two or more states of a cell. Knowing the enrichment of gene sets defined by functional categories. ...
Environmental enrichment strategies for nursery piglets and efficacy for maintaining interest
(2020-01-01)
Context: Animals in situations of stress and constant fear exhibit unwanted behaviours for production. Pigs that are afraid of humans tend to associate any management as stressful. The use of environment enrichment for ...
