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 ...

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

Method of Postures Selection for Industrial Robot Joint Stiffness Identification
IEEE Access, 2021 Industrial robots are being widely applied to machining operations, and are gradually becoming competitive with traditional CNC machining centers. Obtaining accurate stiffness values of robotic joints is the foundation for deflections compensation in ...

Ellipsis, economy, and the (non)uniformity of traces [PDF]
, 2016 A number of works have attempted to account for the interaction between movement and ellipsis in terms of an economy condition Max- Elide. We show that the elimination of MaxElide leads to an empirically superior account of these interactions.

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,

Error Analysis and Model Adaptivity for Flows in Gas Networks
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018 In the simulation and optimization of natural gas flow in a pipeline network, a hierarchy of models is used that employs different formulations of the Euler equations. While the optimization is performed on piecewise linear models, the flow simulation is

Quantitative Controllability Analysis of IEEE Power Network
IEEE Access, 2020 The previous research on the controllability of complex networks is qualitative issue which can only identify whether the network is controllable or not, and it is difficult to assess the controlled ability of network.

Solving ill-conditioned linear equations using simulated annealing method [PDF]
Journal of Hyperstructures, 2018 The purpose of this paper is to using the Simulated Annealing method to solving a linear equations system which have an ill-conditioned coefficients matrix. A linear equation system is called ill-conditioned if its condition number be large.
