Evaluation of Two Tension Sensors for Cable‐Driven Parallel Manipulators
Journal of Field Robotics, Volume 42, Issue 4, Page 1191-1208, June 2025.ABSTRACT Cable‐driven parallel manipulators (CDPMs) constitute a class of parallel robots in which the frame is connected to the end‐effector through a set of cables. The weight reduction achieved by replacing rigid links with cables, along with their exceptionally large workspace, makes CDPMs suitable for applications such as positioning devices ...

Nullities of submatrices of the Moore-Penrose inverse
Linear Algebra and its Applications, 1987 AbstractLet A be a complex m×n matrix of rank r and with Moore-Penrose inverse A†. If A=A11A21a12A22, A†:=B11B21B12B22 are partitioned so that Aii is mi×ni and Bii is ni×mi with m=m1+m2, n=n1+n>2, and if the row nullity of a matrix is denoted by η(), then -(m-r)⩽η(B22)-η(A11)⩽n-r.

Representations for Moore-Penrose inverses in Hilbert spaces
Applied Mathematics Letters, 2001 AbstractLet H1, H2 be two Hilbert spaces, and let T : H1 → H2 be a bounded linear operator with closed range. We present some representations of the perturbation for the Moore-Penrose inverse in Hilbert spaces for the case that the perturbation does not change the range or the null space of the operator.

New representations for the Moore-Penrose inverse [PDF]
The Electronic Journal of Linear Algebra, 2011 In this paper, some new representations of the Moore-Penrose inverse of a complex m × n matrix of rank r in terms of (s × t)-constrained submatrices with msr, ntr are presented.

Recurrent Neural Networks for Computing the Moore‐Penrose Inverse with Momentum Learning
Chinese journal of electronics, 2020 We are concerned with a kind of iterative method for computing the Moore-Penrose inverse, which can be considered as a discrete-time form of recurrent neural networks.

Some Results on Generalized Inverse of Intuitionistic Fuzzy Matrices
Fuzzy Information and Engineering, 2014 In this paper, pseudo-similar intuitionistic fuzzy matrix (IFM) is defined with some properties of pseudo-similar and semi-similar IFMs studied. Here it is shown that, the pseudo-similarity relation preserve idempotency and regularity for the IFMs. After

Review and Analysis of Digital Signal Processing Algorithms for Coherent Optical Satellite Links
International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 229-250, May/June 2025.ABSTRACT Coherent optical satellite links enable high‐throughput communication and high accuracy ranging to and between satellites. Due to the ever‐increasing demand for throughput, wavelength division multiplexing of polarization multiplexed optical signals is being considered as a solution to provide high‐speed optical satellite links.

IEEE Microwave Magazine, 2020 Digital predistortion (DPD) is the linearization technique most often used to cope with the inherent tradeoff between linearity and efficiency in power amplifiers (PAs). Adaptation is needed to optimize DPD performance.

Mathematical Methods in the Applied Sciences, Volume 48, Issue 8, Page 8806-8817, 30 May 2025.ABSTRACT In this paper, we propose a new parametric family of iterative schemes to compute the inverse of a complex nonsingular matrix. It is shown that the members of this family have at least a fourth order of convergence. A particular element of the class is extended to approximate the Moore–Penrose inverse of rectangular complex matrices, keeping ...
