Long period gratings, based on anti-resonant hollow core fibers (AR-HCFs), are fabricated using a high-frequency CO _2 laser pulse by carving periodic grooves.This device exhibits both axial strain and bending sensing characteristics.Benefiting from the low thermal sensitivity and radiation resistance characteristic of AR-HCFs, this grating Horse S

Automated detection of the cricket pitch is a fundamental step in content-based indexing and Horse Skin summarization of cricketvideos.In this paper, we propose visual-content based algorithms to automate the extraction of video frames with thecricket pitch in focus from input cricket videos.As a preprocessing step, we first select a subset of fram

The traditional dynamic characteristic analysis of the multi-stage centrifugal pump rotor system is developed assuming the bearing structural parameters with constant values.However, the manufacturing errors will cause the structural parameters to vary around their nominal values and then affect the dynamic characteristics of the bearing-rotor syst
