Gauge invariance, polar coordinates and inflation
We point out the necessity of resolving the apparent gauge dependence in the quantum corrections of cosmological observables for Higgs-like inflation models.

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 ...

Implicit Guidance Equations in Polar Coordinates [PDF]
In this paper, implicit guidance equations are derived in polar coordinates. Depending on applications, implicit guidance equations in polar coordinates may be preferred over cartesian coordinates.

Integer Polar Coordinates for Compression [PDF]
This paper introduces a family of integer-to-integer approximations to the Cartesian-to-polar coordinate transformation and analyzes its application to lossy compression. A high-rate analysis is provided for an encoder that first uniformly scalar quantizes, then transforms to "integer polar coordinates," and finally separately entropy codes angle and ...

Gn blending multiple surfaces in polar coordinates [PDF]
International audienceThis paper proposes a method of Gn blending multiple parametric surfaces in polar coordinates. It models the geometric continuity conditions of parametric surfaces in polar coordinates and presents a mechanism of converting a ...

The pillow effect is a key weakening factor in the surface accuracy of mesh antennas. Previous studies, however, have significant limitations in such antennas because they have been largely based on specific assumptions, which have failed to investigate ...
