Understanding the underlying processes and extracting detailed characteristics of rivers is critical has not yet been fully developed. The purpose this study was to examine performance non-linear time series methods on environmental data. Specifically, we performed an analysis water level measurements, extracted from sensors, located specified stations along Nestos River (Greece), with Recurren...

This study investigates geometrical non-linear analysis of composite circular cylindrical shells under external pressure over part of their surfaces and also shells subjected to combined axial compression and triangular external pressure. Donnell non-linear shell theory along with first order shear deformation theory (FOSD) are adopted in the analysis. In the case of combined axial compression ...

The technique of estimating the complex frequency components a signal in presence noise based on assumptions about number is known as estimation. problem estimation appears when we receive from transmitter with frequency, and it often radar, sonar, etc. applications. This has been dealt by various techniques algorithms. research shows methods used researchers to estimate paper discusses between...
