We describe an accurate periodic boundary condition (PBC) called the symmetric PBC in the calculation of the magnetostatie interaction field in the finite-differentiation-method fast-Fourier-transform (FDM-FFT) mi...
We present a new method for image encryption on the basis of simplifed fractional Hartley transform (SFRHT). SFRHT is a real transform as Hartley transform (HT) and furthermore, superior to HT in virtue of the adv...
