This paper focuses on the tracking and synchronization problems of hyperchaotic systems based on active backstepping method. The method consists of a recursive approach that interlaces the choice of a Lyapunov function with the design of feedback control. First, a nonlinear recursive active backstepping control vector is designed to track any desired trajectory in hyperchaotic Wang system. Furt...

Fault detection, isolation and recovery is crucial in semiand fully-autonomous vehicles, particularly such vehicles as planetary rovers, which are far-removed from assistance, human or otherwise, in the event of a fault. Residual generation is a popular and conceptually simple method of model-based fault detection, comparing estimates of system properties with other estimates or measurements of...

This study was to explore the conversion of low-cost bio-residuals into high value-added cellulose nanocrystals. Two enzymatic hydrolyzed residuals (i.e., HRMMW and HRSPW) were collected from two different bio-ethanol producing processes-hydrolyzing medium-milled wood (MMW) and hydrolyzing acid sulfite pretreated wood (SPW), respectively. The results showed that both residuals contained over 20...

For Deepfake detection, residual-based features can preserve tampering traces and suppress irrelevant image content. However, inappropriate residual prediction brings side effects on detection accuracy. Meanwhile, residual-domain are easily affected by some operations such as lossy compression. Most existing works exploit either spatial-domain or features, which fed into the backbone network fo...
