It is shown that the linear convolution required in block filtering can be decomposed into a sum of skew-cyclic convolutions. Such convolutions can be realized efficiently with half-length complex ...

Dose calculations were performed with AAA with inhomogeneity correction, Pencil Beam Convolution (PBC), and AAA without inhomogeneity correction. The plans were delivered and the actual doses were ...

In this work, we describe the development of a new algorithm for the computation of Coulomb-type matrices using the well-known resolution of the identity (RI) or density fitting (DF) approximation.

A novel algorithm based on fractional Fourier circular convolution theorem is proposed to deal with the fractional linear convolution, which is in accordance with the hidden periodicity of the ...

The overlap-and-save method separates the input signal into smaller segments which are then independently processed, which makes this method ideal for parallel processing for example on GPUs. At the ...

To address these issues and enhance the reconstruction of large-scale information in the model, we propose a novel approach called source-independent elastic envelope inversion, employing the ...
