Journal of Time Series Analysis, EarlyView.ABSTRACT The paper deals with the construction of a synthetic indicator of economic growth, obtained by projecting a quarterly measure of aggregate economic activity, namely gross domestic product (GDP), into the space spanned by a finite number of smooth principal components, representative of the medium‐to‐long‐run component of economic growth of a ...

Novel Methods for Computing the Moore-Penrose Inverse of Neutrosophic Fuzzy Matrices [PDF]
Neutrosophic Sets and SystemsIn this paper, we introduce a method for determining the generalized inverse (g-inverse) and the Moore-Penrose inverse of Neutrosophic Fuzzy Matrices (NFMs), along with the necessary conditions.

Journal of Mathematics, 2021 In this paper, we study the reverse order law for the Moore–Penrose inverse of the product of three bounded linear operators in Hilbert spaces. We first present some equivalent conditions for the existence of the reverse order law ABC†=C†B†A†.

The Moore-Penrose inverse of a free matrix
, 2007 A matrix is free, or generic, if its nonzero entries are algebraically independent.Necessary and sufficient combinatorial conditions are presented for a complex free matrix to have afree Moore-Penrose inverse.

Frequency control of droop‐based low‐voltage microgrids with cobweb network topologies
IET Generation, Transmission & Distribution, 2020 When distributed generation (DG) technologies are implemented in an islanded low‐voltage microgrid (LVMG), the topological architecture directly affects the frequency synchronisability. Especially in cases of high DG penetration, the synchronisability of

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1741-1754, October 2026.ABSTRACT Purpose To integrate MR‐based servo navigation in MPRAGE and 3D‐TSE sequences and demonstrate its potential for prospective head motion correction in structural imaging. Methods Repeated modules of servo navigators were inserted before each preparation pulse of MPRAGE and 3D‐TSE sequences (before‐prep) for rapid convergence of motion parameter

On an inequality related to the volume of a parallelepiped
Examples and CounterexamplesThe problem of establishing an upper bound for the volume of a parallelepiped is considered by utilizing an original approach involving a skew-symmetric matrix of order four (along with its Moore–Penrose inverse).

General expressions for the Moore-Penrose inverse of a 2 × 2 block matrix [PDF]
, 1991 The Moore-Penrose inverse of a 2 × 2 block matrix M = m=acbd is discussed. General expressions for the Moore-Penrose inverse for the block matrix M in terms of the individual blocks A, B, C, D are delivered without any restrictions imposed.
