The mechanism involves atmospheric waves that bounce between the upper atmosphere and ground level, amplifying weather patterns and making them more extreme. Scientists call this “stratospheric wave ...

The choice of coordinate system in a bearings-only tracking problem influences the methods used to observe and predict the state of a moving target. Modified Polar Coordinates and Log-Polar ...

With everything said and done, the polar coordinate plotter seems to work just as well as its Cartesian cousins might, orienting it like this has some advantages as well.

Based on polar coordinate, the BUAA researchers developed a printing setup with a rotating mandrel as the substrate, called Polar-coordinate Line-projection Light-curing Production (PLLP) technology.

Spread the loveIntroduction Polar coordinates are an alternative coordinate system to the commonly used Cartesian (rectangular) coordinates. They are particularly useful in situations where data can ...

In this paper, polar and spherical Fourier analysis are defined as the decomposition of a function in terms of eigenfunctions of the Laplacian with the eigenfunctions being separable in the ...

Cartesian 3D Printers enjoy the advantage of being so common and popular that they have now become so much cheaper and more user-friendly. They also function more intuitively – our brains are wired to ...
