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... |

CAVER Analyst 2.0: Analysis and Visualization of Channels and Tunnels in Protein Structures and Molecular Dynamics Trajectories
Motivation: Studying the transport paths of ligands, solvents, or ions in transmembrane proteins and proteins with buried binding sites is fundamental to the understanding of their biological function. A detailed analysis of the structural features influencing the transport paths is also imp... |

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... |

Piecewise rational approximation of square-root parameterizable curves using the Weierstrass form
In this paper we study situations when non-rational parameterizations of planar or space curves as results of certain geometric operations or constructions are obtained, in general. We focus especially on such cases in which one can identify a rational mapping which is a double... |

Skinning and blending with rational envelope surfaces
We continue the study of rational envelope (RE) surfaces. Although these surfaces are parametrized with the help of square roots, when considering an RE patch as the medial surface transform in 4D of a spatial domain it yields a rational parametrization of the domain’s boundar... |
