Computational analysis of non-Fourier motion

Vision Research, 1994
Non-Fourier motion is now commonplace in research on visual motion perception, yet lacks a computational framework. This paper examines this issue based on the observation that many non-Fourier motion stimuli have a simple characterization in the frequency domain, in terms of oriented power distributions that lie along lines (or planes) that do not ...

Non-Fourier heat conduction in IC chip

[1992 Proceedings] Intersociety Conference on Thermal Phenomena in Electronic Systems, 1995
Instead of the classic Fourier equation based on diffusion, a hyperbolic equation based on a wave model has been used to predict the rapid transient heat conduction in IC chips. The peak temperature, spatial difference, and time variation of temperature, which are critical to thermal reliability of the chip, are given and compared with that obtained ...

Non‐fourier encoding with multiple spin echoes

Magnetic Resonance in Medicine, 1997
AbstractThe advantages and limitations of multiple spin‐echo sequences for non‐Fourier encoding are investigated. Complications caused by improper encoding of alternate magnetization pathways due to imperfect refocusing pulses are analyzed. It is shown that mirror image ghosts result if the encoding RF pulse matrix is real‐valued.

Non-Fourier plasma electrodynamics

Physica Scripta, 1994
New exact analytical solutions describing the non-stationary propagation of non-sine electromagnetic waves in plasma are obtained by direct solution of Maxwell equations without the traditional Fourier transformations. Unlike the usual travelling monochromatic waves the fields discussed are distinguished by unequal periods of electric and magnetic ...

Non-Fourier heat conductions in nanomaterials

Journal of Applied Physics, 2011
We study the non-Fourier heat conductions in nanomaterials based on the thermomass theory. For the transient heat conduction in a one-dimensional nanomaterial with a low-temperature step at both ends, the temperature response predicted by the present model is consistent with those by the existing theoretical models for small temperature steps. However,
