Fuzzy Counterparts of Fischer Diagonal Condition in ⊤-Convergence Spaces

Mathematics, 2019
Fischer diagonal condition plays an important role in convergence space since it precisely ensures a convergence space to be a topological space. Generally, Fischer diagonal condition can be represented equivalently both by Kowalsky compression operator ...

An Improved Diagonal Jacobian Approximation via a New Quasi-Cauchy Condition for Solving Large-Scale Systems of Nonlinear Equations [PDF]

Journal of Applied Mathematics, 2013
We present a new diagonal quasi-Newton update with an improved diagonal Jacobian approximation for solving large-scale systems of nonlinear equations. In this approach, the Jacobian approximation is derived based on the quasi-Cauchy condition.

An observation on spaces with a zeroset diagonal [PDF]

Mathematica Bohemica, 2020
We say that a space $X$ has the discrete countable chain condition (DCCC for short) if every discrete family of nonempty open subsets of $X$ is countable. A space $X$ has a zeroset diagonal if there is a continuous mapping $f X^2 \rightarrow[0,1]$ with $\

Analysis on the effect of lateral force variation induced by the lubrication condition between wheel and rail for diagonal wheel load unbalance of railway bogie

Nihon Kikai Gakkai ronbunshu
In recent years, condition monitoring technologies have been widely developed aiming at safer railway operation and maintenance cost reduction. Condition monitoring systems of railway for both from onboard and on track have been widely studied thanks to ...

Quasi-Block Diagonal Dominance Condition for Robust Decentralized Tracking Control

Proceedings of 1994 33rd IEEE Conference on Decision and Control, 1994
The robust tracking control of MIMO systems by means of simple decentralized variable-structure controllers is considered. The model of the system that is assumed to be available is a linear I/O map (e.g., a transfer function matrix) affected by bounded ...

Study of the forming process effects on the wrinkling and thinning percentage of the micro-channels with serpentine layout [PDF]

Hydrogen, Fuel Cell & Energy Storage, 2023
In the present study, the lubricated and non-lubricated stamping processes are used for fabrication of the metallic bipolar plates (MBPPs) with a thickness of 0.1 mm made of SS3316 with a serpentine flow field. Experimental tests together with the finite

Nonorthogonal Approximate Joint Diagonalization With Well-Conditioned Diagonalizers [PDF]

IEEE Transactions on Neural Networks, 2009
To make the results reasonable, existing joint diagonalization algorithms have imposed a variety of constraints on diagonalizers. Actually, those constraints can be imposed uniformly by minimizing the condition number of diagonalizers. Motivated by this, the approximate joint diagonalization problem is reviewed as a multiobjective optimization problem ...

Diagonal Denoising for Spatially Correlated Noise Based on Diagonalization Decorrelation in Underwater Radiated Noise Measurement

Journal of Marine Science and Engineering, 2022
In underwater radiated noise measurement using a vertical linear array, a diagonalization-decorrelation-based diagonal denoising method is proposed to improve the denoising effect for spatially correlated noise.

Cardinalities of DCCC normal spaces with a rank 2-diagonal [PDF]

Mathematica Bohemica, 2016
A topological space $X$ has a rank 2-diagonal if there exists a diagonal sequence on $X$ of rank $2$, that is, there is a countable family $\{\mathcal U_n n\inømega\}$ of open covers of $X$ such that for each $x \in X$, $\{x\}=\bigcap\{{\rm St}^2(x ...

Refined analysis on cross arm arrangement of a 1 000 kV UHV steel tube tower

Zhejiang dianli, 2023
In order to reduce the probability of damage to the cross arm of a 1 000 kV UHV steel tube tower， the general software TTA and the finite element software ANSYS are used for refined analysis on the internal force of the cross arm.
