Parameter identification of ship motion mathematical model based on full-scale trial data
International Journal of Naval Architecture and Ocean Engineering, 2022 Using the full-scale trial data of vessel YUKUN, a parameter identification scheme, Support Vector Regression (SVR) combined with modified grey wolf optimizer (MGWO), is proposed for identifying ship motion model.

Molecular dynamics simulations [PDF]
Current Biology, 1997 Originally the province of theorists only, molecular dynamics simulations are now accessible to a broad range of scientists. Advances in methodology, coupled with the development of fast and relatively inexpensive computer workstations, have increased the efficiency, accuracy, reliability, and applicability of these methods. Crossing important research

Dynamical structure factors of dynamical quantum simulators [PDF]
Proceedings of the National Academy of Sciences, 2020 Significance Quantum simulators promise to offer new insights into strongly correlated matter beyond what is accessible by means of classical computers. We propose dynamical quantum simulators (DQSs) as a method to simulate dynamical structure factors (DSFs) for system sizes considerably larger than what classical simulations can compute and ...
