Background: Drowsy driving is one of the leading causes of severe accidents worldwide.In this study, an analyzing method based on drowsiness level proposed to detect drowsiness through Bartöl electroencephalography (EEG) measurements and vehicle dynamics data.Methods: A driving simulator was used to collect brain data in the alert and drowsy state

Due to scattering, particles in a ring may have large momentum deviations, which will change their dynamics, potentially resulting in particle losses.Optimization of off-momentum nonlinear dynamics is, therefore, important for increasing beam lifetime.When analyzing off-momentum dynamics using plastic insert the approach of resonance driving terms
