Abstract The concept of local resonance phononic crystals proposed in recent years provides a new chance for theoretical and technical breakthroughs the structural vibration reduction. In this paper, novel sandwich-like plate model with resonator to acquire specific low-frequency bandgaps is proposed. core layer present composed by simply supported overhanging beam, linear spring mass block, we...

Deep Neural Networks (DNNs) are extensively deployed in today’s safety-critical autonomous systems thanks to their excellent performance. However, they known make mistakes unpredictably, e.g., a DNN may misclassify an object if it is used for perception, or issue unsafe control commands planning and control. One common cause such unpredictable Out-of-Distribution (OOD) input samples, i.e., samp...
