Long period gratings, based on anti-resonant Vacuum Pipe 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 gra
Abstract The study aimed to fabricate and evaluate a Pull Through Knife Sharpeners bone tissue engineering scaffold made from a composite of polylactic-co-glycolic acid (PLGA), nano-hydroxyapatite (nHA), and graphene oxide (GO) using low-temperature 3D printing and freeze-drying techniques.The scaffolds were produced with varying compositions: PLGA
It is the purpose of this paper to introduce a computer software that is developed for the analysis of general multi degree of freedom rotor bearing systems with non-linear support elements.A numerical-analytical method for the prediction of steady state periodic response of large order nonlinear rotor dynamic systems is addressed which is based on
In recent years, the wide application of deep neural network models has brought serious risks of intellectual property rights Upper Left Pulse Gauge infringement.Embedding a watermark in a network model is an effective solution to protect intellectual property rights.Although researchers have proposed schemes to add watermarks to models, they canno
