In this paper, an implicit finite difference scheme with the shifted Grünwald formula, which is unconditionally stable, is used to discretize the fractional diffusion equations with constant diffusion coefficients. The coefficient matrix possesses the Toeplitz structure and the fast Toeplitz matrix-vector product can be utilized to reduce the computational(More)
In this paper, we provide a novel micro rectangular-shaped long-period fiber grating (MRSLPFG) coated with Fe 3 O 4 nanoparticles as the sensing material and packaged in polydimethylsiloxane (PDMS) for magnetic sensing application. The micro rectangular-shaped grating structures are fully dip coated with the magnetic fluid and heated to form a thin solid(More)
Reed-Solomon (RS) codes play an important role in providing error protection and data integrity. Among various Reed-Solomon decoding algorithms, the Peterson-Gorenstein-Zierler (PGZ) algorithm in general has the least computational complexity for small t values. However, unlike the iterative approaches (e.g., Berlekamp-Massey and Euclidean algorithms), it(More)
