An orthogonal similarity reduction of a matrix into semiseparable form |
An algorithm to reduce a symmetric matrix to a similar semiseparable one of semiseparability rank 1, using orthogonal similarity transformations, is proposed in this paper. It is shown that, while running to completion, the proposed algorithm gives information on the spectrum of the similar initial… | |
A two-dimensional ``flea on the elephant'' phenomenon and its numerical visualization |
Localization phenomena (sometimes called ``{\it flea on the elephant}'') for the operator $L^\varepsilon=-\varepsilon^2 \Delta u + p(\xx) u$, $p(\xx)$ being an asymmetric double-well potential, are studied both analytically and numerically, mostly in two space dimensions within a perturbative… | |

An eigenvalue problem for the anisotropic \Phi-Laplacian |
We study an eigenvalue problem involving a fully anisotropic elliptic differential operator in arbitrary Orlicz-Sobolev spaces. The relevant equations are associated with constrained minimization problems for integral functionals depending on the gradient of competing functions through general… | |

Free-knots spline modelling in thermometer calibration |
The accurate calibration of thousands of thermometers involves the optimzation of the experimental design to save time and costs. A modelling procedure is proposed for the construction of a suitable free-knots cubic spline model. An iterative algorithm is used and a minimum experimental… | |
Modelling phase separation in amorphous solid dispersions |
Much work has been devoted to analysing thermodynamic models for solid dispersions with a view to identifying regions in the phase diagram where amorphous phase separation or drug recrystallization can occur. However, detailed partial differential equation non-equilibrium models that track the… | |
Uniform boundedness of Lagrange operator in some weighted Sobolev-type space |
The authors show the uniform boundedness of the Lagrange operator in some weighted Sobolev-type space. |
