Caccioppoli-type estimates and Hardy-type inequalities derived from weighted p-harmonic problems We obtain Caccioppoli-type estimates for nontrivial and nonnegative solutions to anticoercive partial differential inequalities of elliptic type involving weighted p-Laplacian. Using Caccioppoli-type estimates, we obtain several variants of Hardy-type inequalities in weighted Sobolev spaces. |

Linear computational approach to interpolations with polynomial Minkowski Pythagorean hodograph curves Methods using Pythagorean hodographs both in Euclidean plane and Minkowski space are often used in geometric modelling when necessary to solve the problem of rationality of offsets of planar domains. A main justification for studying and formulating approximation and interpolation algorithms ... |

On partially free boundary solutions for elliptic problems with non-lipschitz nonlinearities We show that the elliptic equation with non-Lipschitz right-hand side, considered on a smooth star-shaped domain Ω subject to zero Dirichlet boundary conditions, might possess a nonnegative ground state solution which violates Hopf’s maximum principle only on a nonempty subset Γ of the&... |

Asymptotic relation for zeros of cross-product of Bessel functions and applications Let $a_{\nu,k}$ be the $k$-th positive zero of the cross-product of Bessel functions $J_\nu(R z) Y_\nu(z) - J_\nu(z) Y_\nu(R z)$, where $\nu\geq 0$ and $R>1$. We derive an initial value problem for a first order differential equation whose solution $\alpha(x)... |

The influence of positive pulses on HiPIMS deposition of hard DLC coatings Diamond-like Carbon (DLC) coatings were deposited by a novel HiPIMS method that incorporates positive voltage pulses at the end of the conventional HiPIMS discharge. Different positive voltage amplitudes were used to evaluate the effect of this operation mode on the discharge process an... |

Comparison of Home Team Advantage in English and Spanish Football Leagues Home team advantage in sports is widely analysed phenomenon. This paper builds on results of recent research that -- instead of points gained -- uses goals scored and conceded to describe home team advantage. Using this approach, the home team advantage is random variable that... |

Stability analysis of optimal mean-variance portfolio due to covariance estimation The objective of this paper is to study the stability of the mean-variance portfolio optimization. The results of the mean-variance optimal selection problem are very sensitive to the model parameters (portfolio calibration window and frequency of portfolio rebalancing). There are presented ... |

A direct and local method for computing polynomial Pythagorean-normal patches with global G1 continuity We present a direct and local construction for polynomial G1 spline surfaces with a piece-wise Pythagorean normal (PN) vector field. A key advantage of our method is that the constructed splines possess exact piece-wise rational offsets without any need for reparametrisations, which in&... |

Násobnost kritických bodů funkcionálů se sedlovou geometrií We study the multiplicity of critical points for continuously differentiable functionals on real Banach spaces. We prove that a functional which satisfies the assumptions of the Saddle Point Theorem and moreover is bounded from below has at least three critical points. Apparently, there... |

The dynamic behavior of the fast rotating system in dependence on operating parameters of bearing supports Typical components of many industrial devices are rotating parts. In case of automotive engines, turbochargers are used in order to increase the engine efficiency. These turbochargers are understood as relatively small rotating parts working in aggressive conditions. Although they are usually... |
