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)
In this paper, we propose using an inductively coupled plasma (ICP) etching technique to fabricate a notched long-period fiber grating (NLPFG) for magnetic sensing application. An optical fiber magnetic field sensor based on NLPFG filled with nanoparticle magnetic fluid is proposed and demonstrated. The magnetic fluid nanoparticles were attached on the(More)
BACKGROUND To assess the short-term impact of a comprehensive, community-based multilevel intervention on knowledge, beliefs and practices with respect to smoking, physical activity and diet in Hangzhou, China. METHODS A non-randomised, controlled, before-after quasi-experimental trial was conducted in two intervention areas and one comparison area. The(More)
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)
Recently two kinds of HSS-based iteration methods to solve the absolute value equation (AVE) are proposed. In present paper, we focus on developing the CSCS-based methods for solving the absolute value equation (AVE) involving the Toeplitz structure, and propose the Picard-CSCS method and the nonlinear CSCS-like iterative method. With the help of(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)
