Time evolution of ground motion-dependent depolarisation at linear colliders [PDF]

open access: yes, 2009
Future linear colliders plan to collide polarised beams and the planned physics reach requires knowledge of the state of polarisation as precisely as possible. The polarised beams can undergo depolarisation due to various mechanisms. In order to quantify

Numerical simulation of flotation bubble motion in a three-phase inner suspension fluid

open access: yes工程科学学报, 2016
To find the motion law and optimum size of floatation bubbles in a three-phase flow,the Eulerian model is used to simulate the motion process of bubbles with different initial diameters in pulps of different concentrations.

Biomechanical analysis of different lifting speeds when using an active exoskeleton

open access: yesFrontiers in Bioengineering and Biotechnology
IntroductionMusculoskeletal disorders (MSDs), especially lower back pain, are common consequences of repetitive and long-term mechanical stress. Exoskeletons offer a promising approach to reduce this stress by supporting the wearer during physical labour.

Effects of an active exoskeleton on the muscle activity of the erector spinae and biceps femoris muscles during lifting with symmetric stoop and squat technique

open access: yesFrontiers in Bioengineering and Biotechnology
IntroductionActive exoskeletons are increasingly used to reduce muscle activity and support lifting tasks. However, the effectiveness of exoskeletons can vary depending on the lifting technique.
