An optimization of FIM method for three-dimensional eikonal equations
A Fast Iterative Method (FIM) for eikonal equations [1] are convenient and optimal in two-dimensional and small three-dimensional models. But it takes a lot of time and random access memory for big three-dimensional models. This article describes the time and ...

Impact of successive iterations of some conformal mappings on simple curves
The problem of transformation of some elementary closed and non-closed curves by means of successive iterations of conformal mapping is considered. Since the analytical description of the equations of images for some conformal mappings is quite complicated, it is convenient to use the Maple computer algebra system to implement the iterative process.

For further cluster analysis, objects are grouped in such a way as to obtain clusters with the most distinct features. In this case, another, iterative, cluster analysis approach is useful, namely, k-means clustering. It is taken to determine the centres of a cluster according to a predetermined number and perform further grouping of objects around the resulting value. The centre of a cluster ...
Dialektik als Logik des Scheins. Zu Kants Lektüre von Michael Piccarts Isagoge
An unrecognised copy (1665) in Kant’s private library of Michael Piccart’s Isagoge (1605), an introduction to the system of Aristotelian philosophy together with Kant’s own remarks on this author (Refl 4160, AA 17, p. 439) can be established as an original source for the Kantian ‘ideosphere’. First, I point out contexts and consequences of Piccart’s Altdorfian Aristotelianism, in contrast to the Königsbergian Aristotelianism (emphasised by Tonelli’s research). To further check the...
On the question of extended two-dimensional non-relativistic supersymmetry
An algorithm for realizing the algebra of two-dimensional supersymmetric quantum mechanics is described. The cases N = 2 and N = 3 are described in detail. The procedure for iterating Darboux transformations is considered separately. In contrast to the one-dimensional case, in which the problem is completely solved by Krum's formulas, iterations of two-dimensional Darboux transformations remain insufficiently understood....

Cyclic version of “ – ” iterative method. Estimations of speed of algorithm convergence
Differences methods of the approximate solution of the two-dimensional equation of ions diffusion with the mixed derivatives and the first derivatives of a divergent look are considered. Test calculations on a modeling task with the known analytical decision are carried out. Operability of algorithm is shown and the estimation of speed of its convergence is given.

The nonlinear process dynamic during the signal spreading in the optical lines is considered. The analysis of analytical solves of the equation system that obtained by consistent iterations and stationary phases method show about the "mass center" of signal spectral density displacement to the frequency, that simultaneously satisfy to the phase and group synchronism conditions.
