This research with aim of evaluation the effect of chemical treatment of wood flour on physical, mechanical and morphological properties of polypropylene-nano SiO2 hybrid nanocomposite were done.For this purpose, wood flour with sodium hydroxide and benzyl chloride to chemically treatment.For ensure the chemical treatment, Fourier transform infrare
Using their abundant musculature, frogs are able to exhibit outstanding behavioural versatility.However, understanding the dynamic motion of their 30 + hindlimb muscles, with multi-joint action, and curved pathways, is challenging.This is particularly true in walking, a relatively understudied, but complex frog gait.Building on prior musculoskeleta
COVID-19 vaccines have become pivotal in combating the pandemic since 2019.However, risks stemming from human errors, equipment malfunctions, and emergencies during cold-chain transportation can jeopardize vaccine security without effective safety standards.To ensure COVID-19 vaccine transportation safety, efficiency, and quality while mitigating r
The PID control algorithm for balancing robot attitude control suffers from the problem of difficult parameter tuning.Previous studies have proposed using metaheuristic algorithms to tune the PID parameters.However, traditional metaheuristic algorithms are subject to the criticism of premature convergence and the possibility of falling into local o
