The functions are the response spectra ratio RS Rf), already routinely used in this kind of work, and the elastic energy input ratio EIR(f), defined, for the first time, in this paper.
Most design approaches use the experimental elastic modulus as input variable to describe the material properties.
One of the conclusions is that the coefficient of variation of certain response quantities can become larger than the coefficient of variation of the elastic modulus (the input quantity).
Whereas in the deterministic analysis only mud pressure is varied, for the stochastic study Poisson's ratio, void ratio, elastic modulus (which are inputs representing the material property design variables) and mud pressure are altered in a manner predefined by an assigned statistical distribution pattern, in this case the normal distribution.
The fully coupled nature of the governing equations facilitates control of elastic motion through the input link alone.
The linear elastic case at an input intensity of 0.01 g was also evaluated and is denoted as LE in Fig. 9.
The proposed modal force compensator avoids exciting vibration by the means of canceling out disturbance input to elastic dynamics using modal force generated by CMGs.

Inputs include anisotropic elastic properties, texture and differential scanning calorimetry data, as well as a subset of recent isothermal deformation and load-biased thermal cycling data.
In order to simulate the transient response of the rotating elastic manipulator system, a single-input, single-output state space representation is presented for the system nonlinear model.
