Symplectic Calculation of Lyapunov Exponents
, 1994 The Lyapunov exponents of a chaotic system quantify the exponential divergence of initially nearby trajectories. For Hamiltonian systems the exponents are related to the eigenvalues of a symplectic matrix. We make use of this fact to develop a new method

AI‐Enhanced Vibrational Capsule for Minimally Invasive Detection of Abnormal Bowel Tissue
Advanced Science, EarlyView.A fully integrated vibration‐assisted capsule is presented for the minimally invasive detection of bowel lesions. The capsule incorporates a wireless sensor and an eccentric motor to probe tissue mechanics in situ. By coupling triaxial vibration signals with AI‐based classification and analytical modeling, the system enables early, non‐visual ...

Robust reinforcement learning for nonlinear process control with stability guarantees
Digital Chemical EngineeringReinforcement learning (RL) offers a promising route to fast, nonlinear feedback control for complex process systems; however, its deployment is hindered by the lack of formal stability guarantees and sensitivity to model-plant mismatch under constraints.

Periodic Stabilization of Continuous-Time Multi-Module Impulsive Switched Linear Systems
IEEE Access, 2019 This paper mainly investigates periodic stabilization issue for a class of multi-module impulsive switched linear systems. It is proven that the considered system is exponentially stabilizable if there exists a periodic control Lyapunov function whose ...

Lyapunov Exponents from Node-Counting Arguments
, 1998 A conjecture connecting Lyapunov exponents of coupled map lattices and the node theorem is presented. It is based on the analogy between the linear stability analysis of extended chaotic states and the Schr\"odinger problem for a particle in a disordered

On The Synchronization of Van Der Pol-Duffing Oscillator
Cumhuriyet Science Journal, 2019 Themost well known property of chaotic systems is their sensitivity to initialconditions. In this work the criterion presented in literature forsynchronizing two chaotic systems is applied to a system consisting of two Vander Pol-Duffing oscillators ...

Chaos and Lyapunov exponents in classical and quantal distribution dynamics
, 1997 We analytically establish the role of a spectrum of Lyapunov exponents in the evolution of phase-space distributions $\rho(p,q)$. Of particular interest is $\lambda_2$, an exponent which quantifies the rate at which chaotically evolving distributions ...
