Abstract We present a modal analysis of coupled two-core integrated waveguides fabricated by femtosecond laser writing as function the core-to-core distance, illuminating position and input light wavelength. In order to do that we use correlation filter method, implementing computer generated holograms in phase-only spatial modulator. Due waveguide symmetry, prove it is not necessary encode com...

This paper reports the synthesis of polypyrrole coated SnO2/ZnOelectrospunnanofibers via vapor phase polymerization method. In order to prepare one dimensional (SnO2- ZnO)/polypyrrole with the core sheath structure, first SnO2-ZnO composite nanofibers were synthesized via electrospinning method followed by adsorption of Fe 3+  on the surface of the SnO2-ZnO nanofibers and finally pyrrole w...

The objective of this work was to characterize the cinnamon oil nanocapsule that contained alginate-chitosan as coating agents. In this work, cinamonn oil loaded chitosan nanoparticles (CS-alginate NP-cinamonn) are prepared by a two-step process including oil/water emulsion and ionic gelation. In this study, cinamon as a core material was nanoencapsulated with chitosan alginate at a ratio of 1:...

In this paper a special sandwich panel with a sinusoidal core under distributed load on upper and lower plates has been studied. By drawing free body diagrams, and using energy method and Castagiliano theory the forces and moments involved in the core has been determined. Then, the stresses, normal and horizontal displacements due to above forces and moments are calculated. In order to ensure t...

Purpose: The aim of this study was to investigate the effect of core stabilization exercises on low back pain and abdominal and back muscle endurance in patients with chronic low back pain caused by disc herniation. Methods: For this purpose, 30 male and female patients with chronic low back pain due to disc herniation (age =48.55 ± 3.35) were divided into experimental and control groups (...
