A Novel Camera Calibration Method Based on Polar Coordinate. [PDF]
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]
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
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 ...

Numerical Solution of Heat Equation in Polar Cylindrical Coordinates by the Meshless Method of Lines
We propose a numerical solution to the heat equation in polar cylindrical coordinates by using the meshless method of lines approach. The space variables are discretized by multiquadric radial basis function, and time integration is performed by using ...

Non-commutativity in polar coordinates
We reconsider the fundamental commutation relations for non-commutative $$\mathbb {R}^{2}$$ R 2 described in polar coordinates with non-commutativity parameter $$\theta $$ θ . Previous analysis found that the natural transition from Cartesian coordinates
