An Iterative Algorithm for Imaging of Rough Surfaces Separating Two Dielectric Media
(IEEE-Inst Electrical Electronics Engineers Inc, 2021)
In this article, an efficient algorithm for the reconstruction of a 1-D random rough surface profile separating two lossy dielectric half-spaces is presented. First, the general scattering problem is formulated by the use ...
Experimental investigation of new blank holder approach for incremental forming method
(Springer London Ltd, 2019)
In this study, a new method is developed to reduce the variation of the wall thickness in incremental sheet forming method used in prototype production of sheet metal parts. Unlike the traditional incremental forming method, ...
A simple method to determine high-accuracy refractive indices of liquid crystals and the temperature behavior of the related optical parameters via high-resolution birefringence data
(Elsevier, 2014)
We report new high-resolution experimental data for the optical birefringence over the temperature range spanning the nematic (N) and smectic A (Sm A) phases of various liquid crystals (LCs) by means of a rotating-analyzer ...
A case study on oil pollution in Istanbul Strait: Revisiting 1994 Nassia tanker accident by utilising Potential Incident Simulation Control and Evaluation System (PISCES-II) simulation. What would be different in terms of response if Nassia accident happened today?
(Pergamon-Elsevier Science Ltd, 2020)
Turkey, with her two important straits, is geographically in the middle of one of the major transportation routes and will continue to face risks the oil tankers pose in those sensitive areas. This paper revisits the site ...
High-resolution birefringence investigation of octylcyanobiphenyl (8CB): An upper bound on the discontinuity at the smectic-A to nematic phase transition
(Amer Physical Soc, 2013)
We report optical birefringence data by two different methods with high temperature resolution for octylcyanobiphenyl (8CB) near the smectic-A to nematic (Sm-A-N) phase transition temperature T-AN. Within the resolution ...
Calculation of the inverse relaxation time and the activation energy as a function of temperature for the Raman modes close to the phase transitions in solid nitrogen
(Elsevier, 2021)
The inverse relaxation time is calculated as a function of temperature for the transitions of alpha - beta (P = 0) and epsilon-delta(loc)-delta (at constant pressures) in the solid N-2. For this calculation, the observed ...
Liquid-(Solid plus Liquid) Transitions in a Two-Component System of (CH3)CCl3 + CCl4
(Springer/Plenum Publishers, 2020)
Liquid-(solid + liquid) transitions are studied in (CH3)CCl3 + CCl4 by using the Landau phenomelogical model. The Gibbs energy is expanded in terms of the orientational disorder (OD) parameters for the transitions of the ...
Calculation of the Raman and IR frequencies from the volume data at high pressures in N-2
(Elsevier Gmbh, Urban & Fischer Verlag, 2018)
Raman and IR frequencies of N-2 in the molecular state are calculated as a function of pressure up to 160 GPa by using the volume data from the literature through the mode Gruneisen parameter. By determining the Gruneisen ...
Three-parameter (3P) weibull distribution for characterization of strength of ceramics showing R-Curve behavior
(Elsevier Sci Ltd, 2021)
Strength distribution of advanced ceramics is commonly characterized by two-Parameter (2P) Weibull distribution. However, deviation of strength distribution from 2P-Weibull distribution may occur in ceramics due to various ...
Analysis of the residual stresses and deformations during the autogenous GTAW process
(Emerald Group Publishing Ltd, 2021)
Purpose The gas tungsten arc welding (GTAW) process is a widely used process that produces quality weldments. But the high heat generation from the GTAW arc can cause extreme temperatures as high as 20,000 degrees C. The ...
