On the equivalence of the Rietveld method and the correlated integrated intensities method in powder diffraction
The Rietveld method is the most straightforward and statistically correct approach for the re®nement of crystal structure parameters from powder diffraction data. The equivalent two-stage approach, involving the re®nement of structural parameters based on integrated intensities extracted using the Pawley method, is extremely useful in circumstances such as the global optimization methods of str...
متن کاملQuantitative Phase Analysis Using the Whole-Powder-Pattern Decomposition Method: Application to Ten-Component Mixtures and Natural Products
The procedure for the quantitative phase analysis using the whole-powder-pattern decomposition method has been applied to ten-component mixtures of synthesized ceramic materials and a five-component mixture of natural products. Average deviations of the calculated weight fractions of respective phases from those prepared in mixing were within 1 weight percent (wt.%), and they were smaller than ...
متن کاملCompare Adomian Decomposition Method and Laplace Decomposition Method for Burger's-Huxley and Burger's-Fisher equations
In this paper, Adomian decomposition method (ADM) and Laplace decomposition method (LDM) used to obtain series solutions of Burgers-Huxley and Burgers-Fisher Equations. In ADM the algorithm is illustrated by studying an initial value problem and LDM is based on the application of Laplace transform to nonlinear partial differential equations. In ADM only few terms of the expansion are required t...
متن کاملA Rietveld refinement method for angular- and wavelength-dispersive neutron time-of-flight powder diffraction data
This paper introduces a two-dimensional extension of the well established Rietveld refinement method for modeling neutron time-of-flight powder diffraction data. The novel approach takes into account the variation of two parameters, diffraction angle 2θ and wavelength λ, to optimally adapt to the varying resolution function in diffraction experiments. By doing so, the refinement against angular...
متن کاملSound Source Localization Using a Pinna-based Profile Fitting Method
In a two-microphone approach, interaural differences in time (ITD) and interaural differences in sound intensity (IID) have generally been used for sound source localization. But those cues are not effective for vertical localization in the median plane (direct front). For that purpose, spectral cues based on features of head-related transfer functions (HRTF) have been investigated, but they ar...
