warp and weft spacing and its coefficient of variation affect the physical properties of fabrics such as fabric hand, frictional and mechanical properties. in this paper the weft and warp spacing and its coefficient of variation for plain weave is calculated using fourier transforms. different methods have been used in this work including autocorrelation function. first, two dimensional power s...

In this article, we apply the double ARA–Sumudu transformation (DARA-ST) to nonlocal fractional Caputo derivative operator. We achieve interesting results and implement them solve certain classes of partial differential equations (FPDEs). Several physical applications are discussed analyzed, such as telegraph, Klein–Gordon Fokker–Planck equations. The new technique with DARA-ST is efficient acc...
