In Chapter 5 of the book [12] published in 1983, Draux introduced a generalization of the Gauss quadrature formula for approximating the real-valued linear functionals.The associated results in [45, 49], obtained independently of those from [12], can be considered as straightforward generalizations to the complex case.
For example, for p = 3 and the QNU quadrature scheme, the IGA results are far superior to the Abaqus and Nastran shell elements even in the context of this simple linear elastic problem.
Quadrature oscillators find diverse application in measurement systems [30-33] and in communication circuits, quadrature mixers, SSB-modulator, vector generator, and data conversion.
One of the most important features of the SEM is that the computation of the Lagrange polynomials that are used for the approximation of solution is based on the same GLL-nodes that are necessary to calculate integrals over the region [[OMEGA].sup.e] using the Gauss-Lobatto-Legendre quadrature formula.
The angular variable is usually discretized by replacing angular integrals with quadrature sums.
