Fredholm integral equation of the Laser Intensity Modulation Method (LIMM): Solution with the polynomial regularization and L-curve methods

Journal of Materials Science, 2006
The Laser Intensity Modulation Method (LIMM) is widely used for the determination of the spatial distribution of polarization in polar ceramics and polymers, and space charge in non-polar polymers. The analysis of experimental data requires a solution of a Fredholm integral equation of the 1st kind.

Numerical Comparison Between Tikhonov Regularization and Singular Value Decomposition Methods Using the L Curve Criterion

Journal of Mathematical Chemistry, 2001
To find the solution of the Fredholm integral equation of the first kind \[ \int_a^bK(x,y)f(y) dy=g(x), \] \(c\leqslant x\leqslant d,\) one has to deal with an ill-posed problem and special techniques have to be used. In this paper two of the most common methods, the Tikhonov regularization and the singular value decomposition, are compared when ...

SU‐FF‐T‐108: Computing the Regularization Parameter for Inverse Treatment Planning Using the L‐Curve Method

Medical Physics, 2005
Purpose: Regularization of inverse treatment planning can improve dose uniformity and decrease delivery time of intensity‐modulated radiotherapy (IMRT) thus improving the radiobiological effect. We attempt to select an optimal value of the regularization parameter which improves the smoothness of beam intensity functions without deterioration of ...

Multiplicative Noise and Blur Removal by Framelet Decomposition and -Based L-Curve Method.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society
This paper proposes a framelet-based convex optimization model for multiplicative noise and blur removal problem. The main idea is to employ framelet expansion to represent the original image and use the variable decomposition to solve the problem. Because of the nature of multiplicative noise, we decompose the observed data into the original image ...

31—A simple method for determining the cb(L) curve by cutting and weighing

1963
A cutting and weighing method is described that has the advantage of giving a relatively reliable CB(L) curve with the smallest possible number of observations. The method is based on the cutting of a series of different but consecutive pieces, ascending in length, which together form one “period”.

[The Application of the L-Curve Method in the Retrieval of Temperature Profiles Using Ground-Based Hyper-Spectral Infrared Radiance].

Guang pu xue yu guang pu fen xi = Guang pu, 2018
The thermodynamic profiles of Planetary Boundary Layer could be retrieved by using ground-based hyper-spectral infrared radiance. The AERIoe algorithm has a better performance at the dependency of initial profiles than the “onion peeling” method which was originally applied in the Atmospheric Emitted Radiance Interferometer.
