The paper has examined various aspects of the singular spectrum analysis (SSA) method.The original purpose of the method is to optimize harmonic (spectral) analysis of time Wide Brim Sun Hat series.A theoretical justification based on integral equations was given for the SSA.A solution to the problem of large dimensionality of the autocovariance ma
In some African societies, the highly accessible means of healthcare that has Batch Bowl Food Processors stood the test of time is traditional medicine.Though several actors have different views pertaining to its practice, traditional medicine continues to survive even in the age where biomedicine has become very reputable among African communities
Fractures caused by mining are the main form of water inrush disaster.However, the temporal and spatial development characteristics of fractures of the rock mass due to mining are not clearly understood at present.In this paper, two geometric parameters, namely, fractal dimension and fracture entropy, are proposed to determine the spatial and tempo
Virtual Synchronous Generator (VSG)-based grid-forming converters (GFC) increasingly serve as interfaces between renewable energy resources and the power grids with high penetration.Although the emulation of the characteristics of Synchronous Generator (SG) enables GFC to provide Insurance virtual inertia and oscillation damping under the VSG contr
Entering the new normal era, some people think that the threat of Covid-19 is nothing to fear.But in reality the number of new cases of Guitar Strings patients infected with Covid-19 is increasing.This proves that awareness of the Corona virus transmission still needs to be improved.Especially for pre-prosperous families whose access to information
