Size Distribution of Nanoparticles by Dynamic Light Scattering. Comparison of Bayesian and Tikhonov Inversion Methods
(Taylor & Francis Ltd, 2012-10)
The diameter distribution of nanometric particles is estimated from multiangle dynamic light scattering (MDLS) measurements by solving an ill-conditioned nonlinear inverse problem through Tikhonov and Bayesian methods. ...

A method to deconvolve stellar rotational velocities II: The probability distribution function via Tikhonov regularization
(EDP Sciences, 2016-11)
Aims. Knowing the distribution of stellar rotational velocities is essential for understanding stellar evolution. Because we measure the projected rotational speed v sin i, we need to solve an ill-posed problem given by a ...
Multiangle dynamic light scattering analysis using amodified Chahine method
Multiangle dynamic light scattering (MDLS) is used to determine particle size distributions (PSDs). The angular intensity weighting coefficients used in the inversion of the PSD data affect dramatically the PSD recovered. ...
Recovery of bimodal particle size distributions with multiangle dynamic light scattering
(Chinese Optical Society, 2017-02)
By using the multi-angle dynamic light scattering measurement and the weighted constrained regularization method, the four groups simulated particle systems with bimodal distribution(100/600 nm, 200/600 nm, 300/600 nm, ...
Characterization of Spherical Core-Shell Particles by Static Light Scattering. Estimation of the Core- and Particle- Size Distributions
A numerical method is proposed for the characterization of core-shell spherical particles from static light scattering (SLS) measurements. The method is able to estimate the core size distribution (CSD) and the particle ...
A Neural Network Model for Estimating the Particle Size Distribution of Dilute Latex from Multiangle Dynamic Light Scattering Measurements
The particle size distribution (PSD) of dilute latex was estimated through a general regression neural network (GRNN) that was supplied with PSD average diameters derived from multiangle dynamic light scattering (MDLS) ...
Small-angle X-ray and neutron scattering of polydisperse systems: Determination of the scattering-particle-size distribution

Estimation of the Particle Size Distribution of Colloids from Multiangle Dynamic Light Scattering Measurements with Particle Swarm OptimizationEstimación de distribución de tamaños de partículas de coloides a partir de mediciones de luz dinámica a múltiples ángulos con optimización por enjambre de partículas
(Universidad Nacional de Colombia, 2015-04)
In this paper particle Swarm Optimization (PSO) algorithms are applied to estimate the particle size distribution (PSD) of a colloidal system from the average PSD diameters, which are measured by multi-angle dynamic light ...
