This paper proposes an integral backstepping based nonlinear control strategy for a grid connected wind-photovoltaic hybrid system. The proposed aims at extracting the maximum power available while respecting connection standards. system has reduced number of electronic converters, thereby ensuring lower costs and energy losses, which improves profitability efficiency effectiveness topology met...

Nonlinear responses in transport measurements are linked to material properties not accessible at linear order1 because they follow distinct symmetry requirements2–5. While the Hall effect indicates time-reversal breaking, second-order nonlinear typically requires broken inversion symmetry1. Recent experiments on ultrathin WTe2 demonstrated this connection between crystal structure and response...

M dwarf's atmosphere is expected to be highly magnetized. The magnetic energy can responsible for heating the stellar chromosphere and corona, driving wind. nonlinear propagation of Alfv\'en wave promising mechanism both Based on this scenario, we carried out one-dimensional compressive magnetohydrodynamic (MHD) simulation reproduce atmospheres winds TRAPPIST-1, Proxima Centauri, YZ CMi, AD Leo...

There exist a correspondence between black holes in non linear electrodynamics (NLED) and gravitational collapse of homogeneous dust with semi-classical corrections the strong curvature regime that to our knowledge has not been noticed until now. We discuss nature such explore what insights may be gained from considering NLED context vice-versa.

In order to investigate the influence of various connecting systems on the buckling load of global shallow grid shells, stability analysis were performed in this chapter. Using all of the moment-rotation curves and load displacement curves which were performed in chapter 4, buckling behaviors could be simulated with special consideration to the nonlinear connection stiffness of various connecti...

Modifications to the standard finite element mass matrix are considered with the aim of preserving the positivity of the discrete solution. The approach is used in connection with calculating the initial time derivative values for parabolic equations and in connection with nonlinear Petrov-Galerkin schemes for hyperbolic equations in one space dimension. The extension of the ideas to unstructur...

Abstract. We investigate necessary and sufficient conditions under which a general nonlinear affine control system with outputs can be written as a gradient control system corresponding to some pseudoRiemannian metric defined on the state space. The results rely on a suitable notion of compatibility of the systemwith respect to a given affine connection, and on the output behavior of the prolon...

The recurrent neural interaction in the primary visual cortex makes its outputs complex nonlinear functions of its inputs. This nonlinear transform serves the role of pre-attentive visual segmentation, i.e., the autonomous transformation from visual inputs to processed outputs that selectively emphasize certain features (e.g., pop-out features) for segmentation. Understanding the nonlinear dyna...

We consider the hierarchy of higher-order Riccati equations and establish their connection with the Gambier equation. Moreover we investigate the relation of equations of the Gambier family to other nonlinear differential systems. In particular we explore their connection to the generalized Ermakov–Pinney and Milne–Pinney equations. In addition we investigate the consequence of introducing Okam...
