Gauss quadrature rules associated with a nonnegative measure with support on (part of) the real axis find many applications in Scientific Computing. It is important to be able to estimate the quadrature error when replacing an integral by an l-node G

The use of sampling methods in computing eigenpairs of two-parameter boundary value problems is extremely rare. As far as we know, there are only two studies up to now using the bivariate version of the classical and regularized sampling series. Thes

In this article, we introduce a surface reconstruction method that has excellent performance despite nonuniformly distributed, noisy, and sparse data. We reconstruct the surface by estimating an implicit function and then obtain a triangle mesh by ex

A 4-node, 8-DOF non-conforming quadrilateral element with four internal modes, denoted as iQ8, is developed. It takes the four edges' midpoints of the linear element Q4 as the internal virtual nodes, whose shape functions are the same as those of the

Discontinuities in the stock price at ex-dividend dates make it hard to derive mathematically elegant solutions for European-style options with discrete dividends under the piecewise lognormal model. Numerical schemes such as non-recombining trees ar

An efficient spatial correlation approximation for clustered multiple-input multiple-output channels based on a hierarchical angle structure is presented. To avoid complicated numerical integrations, different approximations have been proposed in the

We propose a new reduced integration rule for isogeometric analysis (IGA) based on the concept of variational collocation. It has been recently shown that, if a discrete space is constructed by smooth and pointwise non-negative basis functions, there

We develop quadrature rules for the isogeometric analysis of wave propagation and structural vibrations that minimize the discrete dispersion error of the approximation. The rules are optimal in the sense that they only require two quadrature points
