Limit Theorems for Twists of L-Functions of Elliptic Curves. IV
Mathematical Modelling and Analysis, 2014 In this paper, we prove a multidimensional limit theorem for moduli of twists of L-functions of elliptic curves. The limit measure in this theorem is defined by the characteristic transforms.

Ядерна фізика та енергетика, 2019 Within the framework of the problem of spectrum deconvolution, variant of the choice of the regularization parameter by criterion of the L-curve, based on the displacement along the points of the L-curve graph, is proposed. An analysis of dependencies on

Selecting the corner in the L-curve approach to Tikhonov regularization [PDF]
IEEE Transactions on Biomedical Engineering, 2000 The performance of two methods for selecting the corner in the L-curve approach to Tikhonov regularization is evaluated via computer simulation. These methods are selecting the corner as the point of maximum curvature in the L-curve, and selecting it as the point where the product of abcissa and ordinate is a minimum.

Regularized MFS solution of inverse boundary value problems in three-dimensional steady-state linear thermoelasticity [PDF]
, 2016 We investigate the numerical reconstruction of the missing thermal and mechanical boundary conditions on an inaccessible part of the boundary in the case of three-dimensional linear isotropic thermoelastic materials from the knowledge of over-prescribed ...

Computational Topology Counterexamples with 3D Visualization of Bézier Curves
Applied General Topology, 2012 For applications in computing, Bézier curves are pervasive and are defined by a piecewise linear curve L which is embedded in R3 and yields a smooth polynomial curve C embedded in R3. It is of interest to understand when L and C have the same embeddings.

Regularization Parameter Determination for Optical Flow Estimation using L-curve [PDF]
The KIPS Transactions:PartB, 2007 An L-curve corner detection method is proposed for the determination of the regularization parameter in optical flow estimation. The method locates the positive peak whose curvature difference from the just right-hand negative valley is the maximum in the curvature plot of the L-curve. while the existing curvature-method simply finds the maximum in the
