Dispersion in GeO2-SiO2 glasses.
Germania glass was prepared from high purity GeO2 powder. Refractive-index dispersion was used to calculate material dispersion and to provide a model for representing the dispersion of GeO2-SiO2 glasses. The wavelength of zero material dispersion is found to be in agreement with theoretical calculations. Modal propagation is modeled for a GeO2 core-silica clad fiber. Results support compositio...
متن کاملCentral Composite experimental design applied to removal of phenanthrene and acenaphthene from soil samples
Abstract In this work, removal of phenanthrene and acenaphthene, as a representative of polycyclic aromatic hydrocarbons, was investigated from soil samples by the soil washing remediation method combined with Central Composite Design. Response surface methodology was utilized to investigate the individual and interactive effects of three variables of removal process including surfactant solut...
متن کاملThe Relationship between Structural and Optical Properties of GeO2-PbO Glasses
The structural and optical characterization of bulk GeO2-PbO glasses was the goal of this study. In this regard, six different (100-x)GeO2-xPbO (15<x<45) glasses were prepared by conventional melt quenching technique between two steel sheets. The produced samples were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) and UV-Vis s...
متن کاملAdaptive Experimental Design Applied to an Ergonomics Testing Procedure
Nonlinear constrained optimization algorithms are widely utilized in artifact design. Certain algorithms also lend themselves well to design of experiments (DOE). Adaptive design refers to experimental design where determining where to sample next is influenced by information from previous experiments. We present a constrained optimization algorithm known as superEGO (a variant of the EGO algor...
متن کاملSilicon films with gallium-rich nanoinclusions: from superconductor to insulator
Si films sputter deposited on thermally oxidized Si are enriched with Ga by ion implantation through a SiO2 capping layer. The morphology and the electrical transport properties of these films are investigated after rapid thermal annealing. Amorphous, Ga-rich nanoinclusions are embedded in a nanocrystalline Si matrix. The metallic nanoinclusions become superconducting below 7K. They form a rand...
