Seismic bearings have been used to mitigate the harmful effect of earthquakes. Torsion mode, one most important irregularities, generally increases shear forces vertical members such as columns and walls in turn this may results brittle failure reinforced concrete (RC) members. Accordingly, it is vital eliminate torsion mode or switch higher modes with lower mass contribution. This study has ev...

The following article investigates nonlinear symmetric buckling of moderately thick circular Nano plates with an orthotropic property under uniform radial compressive in-plane mechanical load. Taking into account Eringen nonlocal elasticity theory, principle of virtual work, first order shear deformation plate theory (FSDT) and nonlinear Von-Karman strains, the governing equations are obtained ...

In the present paper, the focus is on the evaluation of steel dual-system frame buildings using four main types of structural analysis (Linear Static, Linear Dynamic, Nonlinear Static and Nonlinear Dynamic Analyses) with regard to "Seismic Rehabilitation Code for Existing Buildings in Iran" (based on FEMA 273 and 356) where the first two authors of the article tend to follow the previous work (...

We present the first experimental results for polarization-switched QPSK (PS-QPSK) and make a comparison with polarization-multiplexed QPSK. Our measurements confirm the predicted sensitivity advantage of PS-QPSK. We have also studied the single channel performance after transmission over 300 km and support the results with numerical simulations. It is shown that the two modulation formats have...

An empirical study of the bivariate probability distribution characterizing a full set of two consecutive price increments x and y for a group of stocks at time scales ranging from one minute to thirty minutes reveals asymmetric structures with respect to the axes y = 0, y = x, x = 0 and y = −x. All four asymmetry patterns remarkably resemble a four-blade mill called market mill pattern. The fo...

Abstract A recommender system imposes differences between users, by presenting to them different recommendation lists, which they respond to, resulting in “reaction” lists. Comparison of the and reaction lists can indicate user states. Users approve imposed difference, end up narrowing difference (pulling each other closer) consuming more items common or enlarge (pushing further apart) not comm...

A(2)B(2)-type push-pull porphyrins with a strong intramolecular dipole moment have been prepared via Heck and Suzuki coupling reactions as novel materials for use in nonlinear optics (NLO); they display saturable (SA) and reverse saturable absorption (RSA) properties at 532 nm and their nonlinear optical response is characterized by RSA occurring at lower intensity levels whereas the onset of S...
