Robust Parameter Estimation of an Empirical Manoeuvring Model Using Free-Running Model Tests

open access: yesJournal of Marine Science and Engineering, 2021
The work presents the identification and validation of the hydrodynamic coefficients for the surge, sway, and yaw motion. This is performed in two ways: using simulated data and free-running test data.

Singularity, Wielandt’s lemma and singular values

open access: yesJournal of Computational and Applied Mathematics, 2010
The authors obtain some upper and lower bounds for the largest and the smallest singular values of certain complex matrices based on the entries and diagonal dominance. A relationship between largest singular value of a block matrix and its block norm matrix is obtained. Numerical examples are given to demonstrate the usefulness of their results.

Variational Quantum Singular Value Decomposition [PDF]

open access: yesQuantum, 2021
Singular value decomposition is central to many problems in engineering and scientific fields. Several quantum algorithms have been proposed to determine the singular values and their associated singular vectors of a given matrix.

The singular values of the GOE

open access: yesRandom Matrices: Theory and Applications, 2015
As a unifying framework for examining several properties that nominally involve eigenvalues, we present a particular structure of the singular values of the Gaussian orthogonal ensemble (GOE): the even-location singular values are distributed as the positive eigenvalues of a Gaussian ensemble with chiral unitary symmetry, while the odd-location ...

Perturbation Results for Singular Values [Elektronisk resurs]

open access: yes, 1999
The singular values of a perturbed complex-valued matrix A+epsilon B + O(epsilon2) are shown to have singular values of the form sigmai(epsilon)=sigmai + kiepsilon + O(epsilon2). Explicit expressions for the ki coefficients are derived. The cases of zero

The Stability Analysis of Linear Systems with Cauchy—Polynomial-Vandermonde Matrices

open access: yesAxioms, 2023
The numerical approximation of both eigenvalues and singular values corresponding to a class of totally positive Bernstein–Vandermonde matrices, Bernstein–Bezoutian structured matrices, Cauchy—polynomial-Vandermonde structured matrices, and quasi ...

Singular Higher-Order Complete Vector Bases for Finite Methods [PDF]

open access: yes, 2004
This paper presents new singular curl- and divergence- conforming vector bases that incorporate the edge conditions. Singular bases complete to arbitrarily high order are described in a unified and consistent manner for curved triangular and ...

On the singular value decomposition of (skew-)involutory and (skew-)coninvolutory matrices

open access: yesSpecial Matrices, 2020
The singular values σ > 1 of an n × n involutory matrix A appear in pairs (σ, 1σ{1 \over \sigma }). Their left and right singular vectors are closely connected. The case of singular values σ = 1 is discussed in detail. These singular values may appear in

Robustness Analysis of a Class of Decentralized Control Systems [PDF]

open access: yesModeling, Identification and Control, 1986
The paper presents a method for analysing the robustness properties of a class of decentralized control systems. Perturbations both in local and in interconnection parameters are dealt with. The method is based on the use of singular values.
