The present work is devoted to the construction of asymptotically optimized equations of the hyperbolic boundary layer in thin shells of revolution in the vicinity of the dilation wave front at shock edge loading of the tangential type.These equations are map of frank church wilderness derived by asymptotically integrating of the exact three-
This paper proposes a new method of harmonic identification named DQ axis with Fourier (DQF) method.It lies on the basis of the DQ axis method enhanced by the sliding window Fourier analysis (SWFA).The SWFA component and the zero-sequence bo bichette cleats current considered inside the DQF method account for its excellent results on harmonic elimi
The COVID-19 pandemic put forward a new test for an economic resilience study.Its long-term and diffusive spatiotemporal characteristics suggest that we need to pay attention to the resilience and spatial heterogeneity of cities over a longer period.This paper applied SARIMA and the performance curve to measure the economic resilience of each city
The obtainment of a dynamical logic gate (DLG), which is a device capable of implementing several logic functions using the same model, has been one of the goals of the scientific community.Dynamical systems, specifically those that display chaotic behavior, have been widely used to emulate different logic gates which are the basis of general-purpo
