The Effects of Different Optokinetic Drum Rotation Speeds on Motion Sickness Symptoms, Cognitive Performance and Sleep Amount
… first study examined the effects of different rotation speeds (0 RPM, 5 RPM, and 10 RPM) of the optokinetic drum on motion sickness symptoms. Motion sickness symptoms were measured using the Simulator Sickness Questionnaire (SSQ). Before exposure to the optokinetic drum, participants were not …

Granular flow modelling of rotating drum flows using positron emission particle tracking
… and operated in batch mode across a range of drum rotation speeds that span cascading and cataracting Froude regimes. After averaging the PEPT outputs into representative volume elements, subsequent continuum analysis of the flowing layer revealed a rich coexistence of flow regimes - (i) …

Improving the performance of polypropylene matrix composite materials using engineered hemp fibre mats
… using DSF possess alignment with respect to the drum rotation direction (machine direction). Based on the literature, it was expected that nozzles with higher contraction ratios and circular exit shape would result in improved alignment of fibres within the mats compared to the nozzles with lower …
