Query: Measuring Quasi-Static and Kinetic Coefficient of Restitution
  Simultaneously using Levitation Mass Method: Experiment and Simulation   Observed peaks in a levitation mass method (LMM), which are usually addressed
to signal noise, are discussed in this work. This phenomenon arises due to
bounce from plate which is collided by moving part in LMM measurement system.
Normally, the moving part and the plate stick very good after their first
contact. Simulation using molecular dynamics (MD) method is performed to prove
the bounce prognosis.
