Using gravitational lensed images to investigate the intrinsic AGN variability [PDF]

open access: yes, 2016
We discuss about how the relative flux densities among the images of gravitationally-lensed active galactic nuclei, AGN, can be used to study the intrinsic AGN variability with high accuracy.

Curvature-related eddy-current losses in laminated axial flux machine cores [PDF]

open access: yes, 2005
In this paper we present an axiperiodic quasi-static model to evaluate the magnetic flux density distribution and power loss due to curvature related radial flux in the laminated core of axial flux machines.

Pulsed-field magnetization of drilled bulk high-temperature superconductors: flux front propagation in the volume and on the surface [PDF]

open access: yes, 2009
We present a method for characterizing the propagation of the magnetic flux in an artificially drilled bulk high-temperature superconductor (HTS) during a pulsed-field magnetization.

Comments on Flux and Flux Density

open access: yesHortScience, 1988
Abstract A recent update supplement of the ASHS Publications Manual (1) states that photosynthetic photon flux density (PPFD) shall now be called photosynthetic photon flux (PPF). This decision appears to be based on a Feature article by Holmes et al.
