چکیده
Searching for novel signal processing theories and methods has always been a research hotspot in the field of modern processing. The existing transform dealing with non-stationary signals are based on traditional Cartesian coordinates, which very inconvenient to deal naturally described by polar coordinates. This paper studies two-dimensional offset linear canonical (OLCT) Firstly, definition OLCT coordinates is proposed, Hankel (OLCHT) formula derived. Secondly, relationship between OLCHT revealed through angular periodic function. Then, some properties proved mentioned relationship. Finally, proposed applied computed tomography. effectiveness feasibility method verified simulation experiments.

Elzaki transform method for finding solutions to two-dimensional elasticity problems in polar coordinates formulated using Airy stress functions
In this paper, the Elzaki transform method is used for solving two-dimensional (2D) elasticity problems in plane polar coordinates. Airy stress function was used to express the stress compatibility equation as a biharmonic equation. Elzaki transform was applied with respect to the radial coordinate to a modified form of the stress compatibility equation, and the biharmonic equation simplified t...

Abstract In this work, the Mellin transform method was used to obtain solutions for the stress field components in two dimensional (2D) elasticity problems in terms of plane polar coordinates. the Mellin transformation was applied to the biharmonic stress compatibility equation expressed in terms of the Airy stress potential function, and the boundary value problem transformed to an algebraic ...
متن کاملFilterbank Reconstruction of Periodic Signals and Sampling in Polar Coordinates
This paper introduces a new reconstruction formula for reconstructing a periodic bandlimited signal from its nonuniform samples, as well as filterbank interpretations of various sampling strategies, which lead to efficient interpolation and reconstruction methods. As an example of a potential application of these results, we apply it to the problem of reconstructing a two-dimensional bandlimite...
متن کاملVisualization of High-Dimensional Data with Polar Coordinates
INTRODUCTION Many applications in science and business such as signal analysis or costumer segmentation deal with large amounts of data which are usually high dimensional in the feature space. As a part of preprocessing and exploratory data analysis, visualization of the data helps to decide which kind of method probably leads to good results. Since the visual assessment of a feature space that...
متن کاملBetweenness in Polar Coordinates
betweenness, geometry, lines, polar coordinates, trilinear coordinates We consider straight line drawings. From a graph theoretic point of view these are plane graphs with a set of preferred paths. This graph is expressed in geometric terms through the consideration of the betweenness of the points of intersection along each of the lines. If we fix a reference system for polar coordinates, we c...
