OPTIMIZATION OF 3D LOCAL ORIENTATION MAP CALCULATION IN THE MATLAB FRAMEWORK

open access: yesInformatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2015
This paper presents the development and evaluation of a new approach toward the optimization of 3D local orientation map calculation in the Matlab framework. This new approach can be detailed as: optimize eigenvector calculation for PCA analysis of X-ray

New approach for 2-D spectrum estimation——parameter weight method

open access: yesTongxin xuebao, 2006
A new approach of 2-D MUSIC algorithm was proposed.Using the eigenvector and the eigenvalue of the co-variance matrix simultaneously,the method was composed of two one-dimension searching and avoided the costly 2-D searching.The pairings of the estimated

Vortex-induced vibration of two elastically connected bodies: experimental verification of lock-in to multiple eigenmodes

open access: yesJournal of Fluid Science and Technology, 2017
This study examines experimentally the vortex-induced vibration (VIV) of a mechanical system with two eigenmodes. A previous experiment setup was refined to enable the experiment, and was placed in a circulating water channel to submerge a movable ...

On Common Quasi-eigenvector Problems

open access: yes, 2011
[[abstract]]In this paper, we study four types of common quasi-eigenvector problems and two types of eigenvector problems. The existence theorems for the solutions of common quasi-eigenvector problems and eigenvector problems are also ...

Newton's method for the common eigenvector problem [PDF]

open access: yes, 2008
In El Ghazi et al. [Backward error for the common eigenvector problem, CERFACS Report TR/PA/06/16, Toulouse, France, 2006], we have proved the sensitivity of computing the common eigenvector of two matrices A and B, and we have designed a new approach to

Covariance expressions for eigenvalue and eigenvector problems [PDF]

open access: yes, 2016
There are a number of important scientific and engineering problems whose solutions take the form of an eigenvalue--eigenvector problem. Some notable examples include solutions to linear systems of ordinary differential equations, controllability of ...

Hub neurons defined with eigenvector centrality.

open access: yes, 2014
A) Illustrative example showing differences between degree and eigenvector centrality measures. Neurons that are more influential in driving local circuit flow are scored higher in the eigenvector centrality measure, whereas neurons that have the largest

A One-Pass Approach for Slope and Slant Estimation of Tri-Script Handwritten Words

open access: yesJournal of Intelligent Systems, 2018
Handwritten words can never complement printed words because the former are mostly written in either skewed or slanted form or in both. This very nature of handwriting adds a huge overhead when converting word images into machine-editable format through ...
