The mechanical properties of fiber composites are greatly affected by the interfacial interactions between the fibers and matrix, and hence the study of interfacial properties becomes critical. This study demonstrates a simple and effective interfacial modification process using polydopamine (PDA) coating with ZnO nanorods to construct a multi‐scale bionic structure on the polyacrylonitrile (PAN)...
In order to reduce the noise content of the fiber optic gyro (FOG) output signal, and to improve the zero drift index of the FOG, the paper uses the programmable logic device FPGA. The LMS algorithm is analyzed and studied, and it is realized by Verilog language programming. The thought of the paper is based on classical finite state machine. Compared with previous programming algorithms, it has a...
A new nonlinear Guassian filter named new 5th-degree cubature Kalman filter is proposed based on the conventional 3rd-degree CKF, for a higher filter accuracy, stronger numeric stability, acceptable computation complexity. The heart of new CKF is 5th-degree spherical and radial rule that a new sampling approach for points and corresponding weights. The 5th-degree CKF may provide a suboptimal solution...
