On the shape of curves that are rational in polar coordinates [PDF]
Computer Aided Geometric Design, 2012 In this paper we provide a computational approach to the shape of curves which are rational in polar coordinates, i.e. which are defined by means of a parametrization (r(t),θ(t)) where both r(t),θ(t) are rational functions. Our study includes theoretical aspects on the shape of these curves, and algorithmic results which eventually lead to an algorithm

Polar coordinates and generalized h-type indices
Journal of Informetrics, 2020 : This article highlights the importance of using polar coordinates when studying functions, in particular in relation to generalized h-type indices. Concretely, generalized h-type indices are essentially polar coordinates.

A Novel Camera Calibration Method Based on Polar Coordinate. [PDF]
PLoS ONE, 2016 A novel calibration method based on polar coordinate is proposed. The world coordinates are expressed in the form of polar coordinates, which are converted to world coordinates in the calibration process.

On the pattern of interannual polar vortex–ozone co-variability during northern hemispheric winter [PDF]
Atmospheric Chemistry and Physics, 2023 Stratospheric ozone is important for both stratospheric and surface climate. In the lower stratosphere during winter, its variability is governed primarily by transport dynamics induced by wave–mean flow interactions. In this work, we analyze interannual

Kernel Density Estimators for Axisymmetric Particle Beams
Instruments, 2023 Bright beams are commonly represented by sampled data in the numerical algorithms used to simulate their properties. However, in these calculations and the analyses of their outputs, the beam’s density is sometimes required and must be calculated from ...
