In this paper, we investigate the global exponential synchronization in complex networks of nonlinearly coupled dynamical systems with an asymmetric outer-coupling matrix. Employing the Lyapunov function approach with some graph theory techniques, we improve the so-called connection graph stability method for the synchronization analysis, that was originally developed by Belykh et al. for symme...

Traditionally, most of the nonlinear control techniques for elastic robotic systems focused on achieving a desired closed-loop behavior by modifying heavily intrinsic properties plant. This is also case tendon-driven systems, where highly couplings lead to several challenges. Following current philosophy exploiting mechanical compliance rather than fighting it, this letter proposes an Elastic S...

Amplitude death is the cessation of oscillations that occurs in coupled nonlinear systems when fixed points are stabilized as a consequence of the interaction. We show here that this phenomenon is very general: it occurs in nonlinearly coupled systems in the absence of parameter mismatch or time delay although time-delayed interactions can enhance the effect. Application is made to synaptically...

Verifying that a parameterized system satisfies certain desired properties amounts to verifying an infinite family of the system instances. This problem is undecidable in general, and as such a number of sound and incomplete techniques have been proposed to address it. Existing techniques typically focus on parameterized systems with a single parameter, (i.e., on systems where the number of pro...

the mechanical properties including elastic stiffness constants as well as bulk modulus of palladium (pd) nanowire were calculated in the constant temperature and pressure (npt), ensemble by molecular dynamics (md) simulation technique. the quantum sutton-chen (q-sc) many-body potential was used to calculate the cohesive energy as well as forces experience by every atoms. the temperature and pr...
