The Fabric Bolt natural fiber (Luffa cylindrica fiber) reinforced epoxy composite has been fabricated and their structural responses (frequency and deflection) have been computed experimentally and numerically first time using the corresponding experimental elastic properties.The numerical responses are obtained with the help of an in-house MATLAB
Saliva is the most valuable oral fluid is critical to the preservation and management of oral health.Saliva containing various organic and inorganic substances provides primary natural protection for teeth and soft tissues in the oral cavity assists in mastication, deglutition and digestion of food.The secretion of saliva can be affected due to var
The ultraviolet pulse detection technology has superiorities in response speed and antijamming capability, so it is extensively applied to insulation detection for electrical equipment.The existing detection and analysis methods have defects, such as failure of precise modeling caused by incomplete analysis of influence factor, poor model Console a
Accurate detection of ripple components of the direct-current (DC) Security signals is essential for evaluating DC power quality.In this study, the combination algorithm based on variational mode decomposition (VMD) and Hilbert transform (HT) is applied to detect and analyze the characteristics of the ripple components of the DC disturbance signals
