Applied electric field effect on light-scattering birefringence of dye-doped liquid crystal molecule and consistent neural network empirical physical formula construction for scattering intensities
Polat, Omer; Yildiz, Nihat; San, Sait Eren (ELSEVIER SCIENCE BV, 2011)In this paper, we realized two objectives. Firstly, birefringence of azo and anthraquinone dye-doped nematic liquid crystal (NLC) molecules was investigated by applied electric field dependent laser scattering intensities. ... -
Light-scattering determination of visco-elastic and electro-optic parameters of azo and anthraquinone dye-doped liquid crystal molecules and consistent neural network empirical physical formula construction for scattering intensities
Yildiz, Nihat; Polat, Omer; San, Sait Eren; Kaya, Nihan (ELSEVIER SCIENCE BV, 2011)In this paper, we achieved two aims. Firstly, laser light-scattering intensities in methyl red (MR) azo and disperse red (DR) anthraquinone dye-doped nematic liquid crystal (NLC) molecules were measured versus scattering ... -
Light-scattering experiments in dye-doped liquid crystals both to determine crystal parameters and to construct consistent neural network empirical physical formulas for scattering amplitudes
Yildiz, Nihat; San, Sait Eren; Polat, Omer (ELSEVIER SCIENCE BV, 2011)The aim of this paper is two-fold. Firstly, static laser light-scattering amplitude measurements in azo-dye doped nematic liquid crystals (NLCs) were made versus scattering angle, temperature and applied bias voltage. Three ... -
Nonlinear experimental dye-doped nematic liquid crystal optical transmission spectra estimated by neural network empirical physical formulas
Yildiz, Nihat; San, Sait Eren; Koysal, Oguz (ELSEVIER SCIENCE BV, 2010)In this paper, two complementary objectives related to optical transmission spectra of nematic liquid crystals (NLCs) were achieved. First, at room temperature, for both pure and dye (DR9) doped E7 NLCs, the 10-250W halogen ... -
A novel method to produce nonlinear empirical physical formulas for experimental nonlinear electro-optical responses of doped nematic liquid crystals: Feedforward neural network approach
Yildiz, Nihat; San, Sait Eren; Okutan, Mustafa; Kaya, Hueseyin (ELSEVIER SCIENCE BV, 2010)Among other significant obstacles, inherent nonlinearity in experimental physical response data poses severe difficulty in empirical physical formula (EPF) construction. In this paper, we applied a novel method (namely ...
