Abstract Some quantum optics researchers might not realize that classical electromagnetism predicts a $$\mathbf {\pi }$$ π phase shift between S- and P-polarized reflection think the coefficients of transverse modes are independent, or such has no measurable consequences. In this paper, we discuss theoretical...
in this research, static stresses analysis of boron nitride nano - tube reinforced composite (bnntrc) cylinder made of poly - vinylidene fluoride (pvdf) subjected to non - axisymmetric thermo - mechanical loads and applied voltage is developed. the surrounded elastic medium is modelled by pasternak foundation. composite structure is modeled based on piezoelectric fiber reinforced composite (pfr...
In this study, the influencing factors on farmers' participation in use of soil and water conservation practices were investigated using the farmers' experiences in Shahroud river basin. For achieving this goal was used from multinomial logit model. The required dates are related to year 2011-2012 that by completing the questionnaire from 138 sample farmers were collected. To select the sample ...
The non-continuous laser beam in pulsed lasers allows the mechanical peening between two consecutive beams on a still hot weld bead. At a very short time (20, 150 and 300 ms) after laser pulse application, mechanical peening was performed on the welding bead. To achieve these short times, the light sensor detects the nth laser pulse and the mechanical arm starts moving. Upon reaching the tip of...
