A Mathematical Analysis of New L-curve to Estimate the Parameters of Regularization in TSVD Method
A new technique to find the optimization parameter in TSVD regularization method is based on a curve which is drawn against the residual norm [5]. Since the TSVD regularization is a method with discrete regularization parameter, then the above-mentioned curve is also discrete. In this paper we present a mathematical analysis of this curve, showing that the curve has L-shaped path very similar t...
متن کاملRheological characterization of composites using a vertical oscillation rheometer.
OBJECTIVES The purpose of this study was to investigate the viscoelastic properties related to the handling characteristics of composites. METHODS A custom-designed vertical oscillation rheometer (VOR) was used for the rheological measurements of composites. The VOR consists of three parts: (1) a measuring unit, (2) a deformation induction unit, and (3) a force-detecting unit. Two medium-visc...

متن کاملNew Estimate of Quark Mass Parameters*
An estimate of quark mass parameters suitable for the study of chiral symmetry breaking effects is made using exact GoldbergerTreiman relations for the Goldstone bosons which appear in the WeinbergSalam theory when the gauge coupling is set to zero. The numbers obtained are m U = 13.75 5.9 MeV, md = 24.7t12.9 MeV, and ms = 4972 299 MeV. Consistency of the various Goldberger-Treiman relations wi...
متن کاملUsing neural network to estimate weibull parameters
As is well known, estimating parameters of the tree-parameter weibull distribution is a complicated task and sometimes contentious area with several methods vying for recognition. Weibull distribution involves in reliability studies frequently and has many applications in engineering. However estimating the parameters of Weibull distribution is crucial in classical ways. This distribution has t...
