This study focuses on the numerical investigation of hull girder loads a flexible containership S175 with intact and damaged conditions advancing in regular head waves. In this study, two-way coupled fluid-structure interactions framework is applied, which between flooding water inside tanks wave fields are modelled by Computational Fluid Dynamics toolbox OpenFOAM. The structural deformation pr...

We apply a simple dynamical rule to determine the dominant forcing direction in locally coupled oceanatmosphere anomalies in the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/ NCAR) reanalysis data. The rule takes into account the phase relationship between the low-level vorticity anomalies and the Sea Surface Temperature (SST) anomalies. Analysis ...

Spatiotemporal chaos of a two-dimensional one-way coupled map lattice is used for chaotic cryptography. The chaotic outputs of many space units are used for encryption simultaneously. This system shows satisfactory cryptographic properties of high security; fast encryption (decryption) speed; and robustness against noise disturbances in communication channel. The overall features of this spatio...

Background: The study investigated the extent of soil arsenic (As) contamination in agricultural plots in Bengal Delta through contaminated groundwater irrigation. Edaphic levels of As and oxidizable organic carbon (OOC) were tested along a depth gradient (0 to 160 ft) in agricultural plots. Methods: Soil samples were collected from surface up to 160 feet depth at every 5 feet. By boreholes dri...

in this paper, non-polynomial spline method for solving coupled burgers’ equations are presented. we take a new spline function. the stability analysis using von-neumann technique shows the scheme is unconditionally stable. to test accuracy the error norms2l, ∞l are computed and give two examples to illustrate the sufficiency of the method for solving such nonlinear partial differential equatio...

In the present paper we study certain characteristic features associated with bifurcations of chaos in a ®nite dimensional dynamical system ± Murali±Lakshmanan±Chua (MLC) circuit equation and an in®nite dimensional dynamical system ± one-way coupled map lattice (OCML) system. We characterize chaotic attractors at various bifurcations in terms of r n …q† ± the variance of ¯uctuations of coarse-g...

We study the dynamics of the travelling interface arising from a bistable piece-wise linear one-way coupled map lattice. We show how the dynamics of the interfacial sites, separating the two superstable phases of the local map, is finite dimensional and equivalent to a toral map. The velocity of the travelling interface corresponds to the rotation vector of the toral map. As a consequence, a ra...
