in this article the relationship between the amount of seasonal rainfall (autumn, winter and spring) and climate indices in iran have been studied. the climate indices (the southern oscillation(soi),the north atlantic oscillation(nao), arctic oscillation(ao),nino 3/4,the multivariate enso index(mei),trans_ nino index(tni) and the pacific decadal oscillation(pdo) are used as independent variable...

Remote loading systems using an electromagnetic beam is affected by discontinuous piecewise constant loading voltage. The characteristics of these remote dynamic systems under charge are investigated. Varied behaviour of the systems with discontinuous charge is found due to environment perturbation compared to systems under continuous voltage charge with a wired link. A theoretical and numerica...

The field of nonlinear optics has developed rapidly since its beginning in 1961. This development is in both the theory of nonlinear effects and the theory of nonlinear interactions in solids, and in the applications of nonlinear devices. This review discusses nonlinear interactions in solids and the resultant nonlinear coupling of electromagnetic waves that leads to second harmonic generation,...

The interplay mechanism between electromagnetic (EM) and electrostatic (ES) turbulence is explored using direct gyrofluid simulations of mixed resistive magnetohydrodynamic (MHD) and ion-scale microinstability. With an elucidation based on a minimal model, we propose a new concept of cross-scale dynamo action induced by microturbulence as the mechanism responsible for the interaction between mu...

It is known that the quantized vortices in a superfluid can be described by a dual electromagnetic model through the duality transformation. Recently a new technique, which can selectively remove atoms from a Bose-Einstein condensate, was applied to the vortex lattice state of the rapid rotating Boson gases. The increase of vortex number, dynamical formation of giant vortex, the oscillation and...

We study the effect of unlinearized medium on the collective excitations in quarkgluon plasma. We present two kinds of non-Abelian oscillation solutions which respectively correspond to weakly and strongly nonlinear coupling of field components in color space. We also show that the weakly nonlinear solution is similar to Abelianlike one but has the frequency shift, which is of order gT , from e...

UNLABELLED One resorts to various postural strategies while attempting to maintain balance. OBJECTIVE To assess the postural strategies adopted by young and elderly subjects in varying sensory conditions by using a system of tridimensional electromagnetic sensors positioned on the projection of the first thoracic vertebra and on the sacral region. Postural oscillation values for young and eld...
