Several Matrix Euclidean Norm Inequalities Involving Kantorovich Inequality

open access: yesJournal of Inequalities and Applications, 2009
Kantorovich inequality is a very useful tool to study the inefficiency of the ordinary least-squares estimate with one regressor. When regressors are more than one statisticians have to extend it.

Flag curvatures of the unit sphere in a Minkowski-Randers space [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2021
On a real vector space $V$, a Randers norm $\hat{F}$ is defined by $\hat{F}=\hat{\alpha}+\hat{\beta}$, where $\hat{\alpha}$ is a Euclidean norm and $\hat{\beta}$ is a covector.

Topologies of Bihyperbolic Numbers

open access: yesMathematics, 2022
In this paper, we establish a correlation between the bihyperbolic numbers set and the semi-Euclidean space. There are three different norms on the semi-Euclidean space that allow us to define three different hypersurfaces on semi-Euclidean space. Hence,

Calculation of likelihood based on quasi-euclidean norm for robust particle-filer-based self-localization

open access: yesNihon Kikai Gakkai ronbunshu, 2014
In this paper, we propose to calculate a likelihood based on a quasi-euclidean norm for a fast and robust particle-filter-based self-localization of mobile robots.

Comparison of Accelerometry-Based Measures of Physical Activity: Retrospective Observational Data Analysis Study

open access: yesJMIR mHealth and uHealth, 2022
BackgroundGiven the evolution of processing and analysis methods for accelerometry data over the past decade, it is important to understand how newer summary measures of physical activity compare with established measures.

A generalisation of the fractional Brownian field based on non-Euclidean norms [PDF]

open access: yes, 2015
We explore a generalisation of the L\'evy fractional Brownian field on the Euclidean space based on replacing the Euclidean norm with another norm. A characterisation result for admissible norms yields a complete description of all self-similar Gaussian ...

Planar separators and the Euclidean norm [PDF]

open access: yes, 1990
In this paper we show that every 2-connected embedded planar graph with faces of sizes d1.....d f has a simple cycle separator of size 1.58 \(\sqrt {d_1^2 + \cdots + d_f^2 }\)and we give an almost linear time algorithm for finding these separators, O(no(n,n)). We show that the new upper bound expressed as a function of ‖G‖=\(\sqrt {d_1^2 + \cdots + d_f^

Minimizing the Euclidean Condition Number [PDF]

open access: yes, 1994
This paper considers the problem of determining the row and/or column scaling of a matrix A that minimizes the condition number of the scaled matrix. This problem has been studied by many authors.

Fractional Vector Cross Product in Euclidean 3-Space

open access: yesInternational Journal of Analysis and Applications, 2023
In this research a new definition of fractional vector cross product of two vectors in Euclidean 3-space is presented. Using this new definition the formulae for Euclidean norm, fractional triple vector cross product, curl and divergence of fractional ...
