the continuum based approaches don’t provide the correct physics in atomic scales. on the other hand, the molecular based approaches are limited by the length and simulated process time. as an attractive alternative, this paper proposes the fixed interfacial multiscale method (fimm) for computationally and mathematically efficient modeling of solid structures. the approach is applicable to mult...

We have been studying coand postseismic displacements from large earthquakes since mid-2006, using ALOS PALSAR images acquired before and after these events. Due to its wavelength, coherence is high even in heavily vegetated areas or steep ranges. We can estimate slip distribution of these earthquakes based on the observed interferograms using a nonlinear inversion scheme. So far, we could not ...

A region in an alternated pair of random-dot patterns was uniiormty displaced. It U:E perceiled ‘1s a segregated. coherently moving shape only if the displacement was smdii. The hmit on the displacement was Its absolute size (maximum about 15’) rather than the number of elements’ widths. Segregation due to apparent motion did not occur if the two patterns were exposed to diKerent eyes. These co...

In this paper we present a new method to estimate optical flow for large displacements. It is based on prediction of global flow field parameters, performs better than multiresolution estimation methods and has been verified using standard test sequences as well as real-world data. Global flow field parameters can be estimated from optical flow measurements in all flow regions. They can then be...

Fluctuations are unavoidable in any physical system but they can be the bane of precision measurements. A way around this is to generate what are called squeezed states. In a squeezed state, the uncertainty in one of a pair of conjugate variables (such as position and momentum) can be reduced below the quantum limit, so long as the product of the variables satisfies the Heisenberg relation. In ...

We have developed a method for measuring the electrophoretic mobility of submicrometer, fluorescently labeled particles and the electroosmotic mobility of a microchannel. We derive explicit expressions for the unknown electrophoretic and the electroosmotic mobilities as a function of particle displacements resulting from alternating current (AC) and direct current (DC) applied electric fields. ...

In this paper, a semi-analytical solution for magneto-thermo-elastic problem in an axisymmetric functionally graded (FG) hollow rotating disk with constant thickness placed in uniform magnetic and thermal fields with heat convection from disk’s surfaces is presented. Solution for stresses and perturbation of magnetic field vector in a thin FG rotating disk is determined using infinitesimal theo...
