Design and Construction a Walnut Peeler
Post-harvest operations have been used in order to increase the efficiency of product production. In the case of walnuts, one of the important processes for improving quality is peeling the walnut’ s shell. Because of the amount of walnuts produced in Iran and the necessity to reduce the loss of products, a device for quick removal of the walnut’ s shell is needed. This study examined and compa...
متن کاملDesign of Photonic Crystal Polarization Splitter on InP Substrate
In this article, we suggested a novel design of polarization splitter based on coupler waveguide on InP substrate at 1.55mm wavelength. Photonic crystal structure is consisted of two dimensional (2D) air holes embedded in InP/InGaAsP material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. The photonic band gap (PBG) of this structure is determined using t...
متن کاملAn Unusual Log-splitter Injury Leading to Radial Artery Thrombosis, Ulnar Artery Laceration, and Scapholunate Dissociation
A log splitter is a gasoline- or diesel-powered machine that uses a hydraulic-powered cutting wedge to do the work of an axe. Log-splitter injuries that do not result in amputation of digits or limbs are uncommon and not well described in the literature. We present a unique case of a patient who sustained a log-splitter injury that resulted in thrombosis of the radial artery and avulsion lacera...
متن کاملA New Design of Photonic Crystal Filter and Power Splitter Based on Ring Resonators
Here, we propose an optical filter and an optical power splitter based on two-dimensionalphotonic crystal all circular ring resonators. These structures are made of a square lattice ofsilicon rods with the refractive index n1=3.464 surrounded by air (with refractive indexn2=1). First, we have designed the filter and by using that, we designed a power splitter. Thetransmission efficiency and Qua...
