Coefficient of restitution for viscoelastic disks [PDF]
Physical Review E, 2007 The dissipative collision of two identical viscoelastic disks is studied. By using a known law for the elastic part of the interaction force and the viscoelastic damping model an analytical solution for the coefficient of restitution shall be given. The coefficient of restitution depends significantly on the impact velocity. It approaches one for small

Watching and listening to the coefficient of restitution
The Physics Teacher, 2011 Abstract We discuss the measurement of the coefficient of restitution (COR) and the acceleration of gravity g using video and sound analysis with both Tracker and Logger Pro 3 software. Measuring COR of a bouncing ball is a common activity in physics labs from high school to intro level college courses (e.g., measuring COR to obtain gravitational ...

Estimation of the restitution coefficient by strain measurement
EPJ Web of Conferences, 2015 In order to clarify the collision phenomenon of the traffic machine in motion, such as automobile and aircraft, it is necessary to examine not only the deformation and the behavior of composed structural member but also the dynamic characteristic of ...

Particle Collision Study Based on a Rotational Boundary Condition
Journal of Marine Science and Engineering, 2023 The main engineering machinery for the hydrodynamic lifting of seafloor mineral particles is rotor machinery with rotating impeller motion. It is important to study the rebound mechanism of collisions between particles and rotating walls to improve the ...

Health Literacy, Self‐Efficacy and Knowledge of Sickle Cell Disease Among Caregivers
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Sickle cell disease (SCD) is a hereditary blood disorder in which abnormal haemoglobin leads to severe anaemia, painful crises and organ failure. Caregivers’ health literacy (HL) – their ability to assess, understand and apply information, and interact with healthcare professionals – is crucial for managing children with SCD, yet ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
