Hausdorff measure of noncompactness of matrix operators on some new difference sequence spaces

Journal of Inequalities and Applications, 2016
The new sequence spaces X ( r , s , t ; Δ ) $X(r,s,t;\Delta)$ for X ∈ { l ∞ , c , c 0 } $X\in\{l_{\infty}, c, c_{0}\}$ have been defined by using generalized means and difference operator.

Continuous Cooling Transformation Behaviour and Bainite Transformation Kinetics of 23CrNi3Mo Carburised Steel

Metals, 2020
In this study, the phase transformation behaviour of the carburised layer and the matrix of 23CrNi3Mo steel was comparatively investigated by constructing continuous cooling transformation (CCT) diagram, determining the volume fraction of retained ...

Pilot Protection for Converter-interconnected Lines Based on Multi-stage Mutation of Fault Current

Zhongguo dianli
The introduction of power electronic converters has altered the fault characteristics of the traditional power grids. Traditional differential protection is inadequate to meet protection requirements when AC lines experience faults, leading to reduced ...

A Note on the Sequence Space b_p^(r,s) (G)

Cumhuriyet Science Journal, 2017
In this study, we define the sequence space  derived by the composition of the Binomialmatrix and generalized difference(double band) matrix and show that the space  is linearly isomorphic to the space , where .

The Functional Gradient Description Method of Space Coordinate Transformation [PDF]

Journal of Geodesy and Geoinformation Science, 2019
The 3-dimension coordinate datum transformation is very important in geomatics. Generally, there are small angle coordinate transformation model (i.e., Bursa model, et al) and large angle coordinate transformation model (i.e., Rodrigo matrix model, et al)

Tensor Eigenvalue and SVD from the Viewpoint of Linear Transformation

Axioms, 2023
A linear transformation from vector space to another vector space can be represented as a matrix. This close relationship between the matrix and the linear transformation is helpful for the study of matrices.

Matrix transformations of double convergent sequences with powers [PDF]

Proceedings of the Estonian Academy of Sciences
In 1967, I. J. Maddox generalized the spaces c0, c, ℓ∞ by adding the powers pk (k ∈ ℕ) in the definitions of the spaces to the terms of elements of sequences (xk). Gökhan and Çolak in 2004–2006 defined the corresponding double sequence spaces
