A new gene tree algorithm employing DNA sequences of bovine genome using discrete Fourier transformation [PDF]
Within the realms of human thoughts on nature, Fourier analysis is considered as one of the greatest ideas currently put forwarded. The Fourier transform shows that any periodic function can be rewritten as the sum of sinusoidal functions.

Digital signal processing in telecommunications based on parametric discrete Fourier transform [PDF]
A generalization of the discrete Fourier transform in the form of a parametric discrete Fourier transform is proposed. The analytical and stochastic properties of the introduced discrete transformation are investigated.

Fourier-spectral-method implementation of deformation in the phase-field crystal model [PDF]
The phase-field crystal (PFC) method is a promising computational model with atomistic resolution and diffusive time scale. In this work, the Fourier-spectral-method (FSM) scheme was developed for evaluating the PFC free energy of a system subjected ...

Construction of Fair Dice Pairs
An interesting and challenging problem in mathematics is how to construct fair dice pairs. In this paper, by means of decomposing polynomials in a residue class ring and applying the Discrete Fourier Transformation, we present all the 2000 fair dice ...
