In this work, the Arrhenius equation was used to determine the change in the properties of rubbers, and the following properties were adopted as the main physicomechanical properties characterizing the life of the vibration isolator: the static modulus, the dynamic modulus, the logarithmic decrement, the development of residual compressive deformation and the hysteresis losses.
The Appendix B continues the discussion regarding the remaining three offerors within this scenario where each of the three remaining offerors are granted the VATEP decrement that they earned as defined within the solicitation.

To quantify repetitive finger movement kinematics, we used linear regression techniques to determine the intercept, which reflects the initial movement amplitude (degree) and initial velocity (degree/s), and the slope, which reflects the amplitude and velocity decrement during the movement repetition.
Another illustration in the VATEP appendix even shows a decrement value attached to receiving a "low" risk.
The linear increment and decrement does not accurately imitate the network load pattern and thus cannot be used for an efficient utilization of the network bandwidth.
