This third of three volumes includes papers from the second series of NODYCON, which was held virtually in February of 2021. The conference papers reflect a broad coverage of topics in nonlinear dynamics, ranging from  traditional  topics from  established streams of research to those from  relatively unexplored and emerging venues of research. These include

·         Complex dynamics of COVID-19: modeling, prediction and control

·         Nonlinear phenomena  in bio-systems and eco-systems  

·         Energy harvesting  

·         MEMS/NEMS          

·         Multifunctional structures, materials and metamaterials

·         Nonlinear waves    



·         Chaotic systems, stochasticity, and uncertainty
