A novel hyperchaotic system derived from asymmetric bidirectional coupling of two Lorenz oscillators: Synchronization analysis and cryptographic applications

This paper investigates a six-dimensional coupled Lorenz system obtained through bidirectional asymmetric diffusive coupling of two identical Lorenz oscillators. The proposed model is analyzed from both dynamical and synchronization perspectives. Dissipativity conditions, equilib...

Stability of a Degenerate Thermoelastic Equation

This work is dedicated to the study of a linear model arising in a thermoelastic rod of homogeneous material. The system results from a coupling of a heat and a wave equation in the interval ( 0 , 1 ) with Dirichlet boundary conditions at the outer endpoints, where the parabolic...

Cyclic response of anisotropic polyurethane foam to multiple static and quasi-static loading tests

Studies on anisotropic mechanical behavior of polyurethane foams under cyclic compression remain limited. This work reports the cyclic compression response of an anisotropic rigid open-cell polyurethane foam (RPUF) tested along the foam rise direction (D1) and the transverse dire...
