Predicting the time derivative of local magnetic perturbations

Some of the potentially most destructive effects of severe space weather storms are caused by the geomagnetically induced currents. Geomagnetically induced currents (GICs) can cause failures of electric transformers and result in widespread blackouts. GICs are induced by the time variability of the magnetic field and are closely related to the time derivative of the local magnetic field perturb...

Local perturbations of generalized systems under feedback and derivative feedback

Following V.I. Arnolds techniques, we construct a local canonical form called miniversal deformation, for a family of differentiable regularizable linear dynamical systems Eẋ(t) = Ax(t)+Bu(t) under feedback and derivative feedback equivalence. We show some applications to the analysis of perturbations of a given regularizable system. c © 2008 Elsevier Ltd. All rights reserved.

Heterogeneous anisotropic magnetic susceptibility of the myelin-water layers causes local magnetic field perturbations in axons.

One goal of MRI is to determine the myelin water fraction in neural tissue. One approach is to measure the reduction in T2 * arising from microscopic perturbations in the magnetic field caused by heterogeneities in the magnetic susceptibility of myelin. In this paper, analytic expressions for the induced magnetic field distribution are derived within and around an axon, assuming that the myelin...

Local Derivative Pattern with Smart Thresholding: Local Composition Derivative Pattern for Palmprint Matching

Palmprint recognition is a new biometrics system based on physiological characteristics of the palmprint, which includes rich, stable, and unique features such as lines, points, and texture. Texture is one of the most important features extracted from low resolution images. In this paper, a new local descriptor, Local Composition Derivative Pattern (LCDP) is proposed to extract smartly stronger...
