Abstract: All dynamic systems exhibit some degree of internal damping. Recent investigations have shown that a fractional derivative model provides a better representation of the internal damping of a ...

Abstract: This paper presents a wavelet based model for stochastic dynamic systems. In this model, the state variables and their variations are approximated using truncated linear sums of orthogonal ...

Abstract: This paper presents a mathematical formulation for a superelement on a moving reference frame. A group of constrained elements, forming a single degree-of-freedom with respect to some reference ...
