Actuators, 2023 This study proposes a method for designing a class of rotationally symmetric Stewart platforms (RSSPs) with an insensitive condition number (ICN), which is used to minimize the condition number to achieve a high accuracy for a multi-degree-of-freedom ...

The Condition Number of Riemannian Approximation Problems [PDF]
SIAM Journal on Optimization, 2021 We consider the local sensitivity of least-squares formulations of inverse problems. The sets of inputs and outputs of these problems are assumed to have the structures of Riemannian manifolds. The problems we consider include the approximation problem of finding the nearest point on a Riemannian embedded submanifold from a given point in the ambient ...

Condition numbers and their condition numbers
Linear Algebra and its Applications, 1995 In this interesting paper condition numbers are treated from the point of view of the unifying definition \[ \text{cond} (A) = \lim_{\varepsilon \to 0_ +} \sup_{\| \Delta A \| \leq \varepsilon \| A \|} {\bigl \| (A + \Delta A)^{-1} - A^{-1} \bigr \| \over \varepsilon \| A^{-1} \|}; \tag{1} \] similarly-defined condition numbers for linear systems are ...

New Insights into the RLS Algorithm
EURASIP Journal on Advances in Signal Processing, 2004 The recursive least squares (RLS) algorithm is one of the most popular adaptive algorithms that can be found in the literature, due to the fact that it is easily and exactly derived from the normal equations.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingAirborne LiDAR bathymetry (ALB) can seamlessly measure land and shallow water areas. However, many factors lead to point cloud thickness and stratification of adjacent swaths, which are unfavorable for generating seafloor topographic maps.

Journal of Advances in Modeling Earth Systems, 2020 We describe a method for reconstructing spatially explicit maps of seasonal paleoclimate variables from site‐based reconstructions. Using a 3‐D‐Variational technique, the method finds the best statistically unbiased, and spatially continuous, estimate of

Sensitivity Analysis of Eigenvalues for PDNT Toeplitz Matrices
AxiomsThis study focuses on a class of perturbed Dirichlet–Neumann tridiagonal (PDNT) Toeplitz matrices, mainly exploring their eigenvalue sensitivity and inverse problems. By the explicit expressions for eigenvalues and eigenvectors of PDNT Toeplitz matrices,
