A new method for electric energy measurement considering the influence of interharmonic

Diance yu yibiao
Among existing mathematical models of electric energy measurement, either the full electric energy is calculated, or the fundamental active electric energy is conducted, or the fundamental and integer harmonic components of electric energy are separately

Computing generalized inverse systems using matrix pencil methods

, 2001
In this very interesting work the numerically reliable computation of: a) the \((1,2)\) or weak inverse, and b) the Moore Penrose inverse, of a general rational matrix is addressed. The most interesting aspect in this work is that it proposes the way to compute stable \((1,2)\) inverses which are very useful in many practical applications.

Inverse problems for discrete Hermite nabla difference equation

Applied Mathematics in Science and Engineering
Inverse problems are studied for discrete Hermite equations with nabla difference including initial value, terminal value and Sturm–Liouville problems. A quantitative study is conducted to obtain the solution.

Tensor decomposition based R-dimensional matrix pencil method

, 2012
In this paper, we extend the standard matrix pencil (MP) method to R-dimensional (R-D) tensor based MP. Higher-order singular value decomposition (HOSVD) is used to obtain the signal subspace. Performance of tensor based MP method is evaluated by computer simulations.
