In this paper a new method is proposed to analyze the mechanical response of a linear viscoelastic pavement. The material parameters of the asphalt concrete are characterized by the relaxation modulus and creep compliance, which are further repr[...]

An alternative to the modeling of the transient behavior of pipeline systems in the time-domain is to model these systems in the frequency-domain using Laplace transform techniques. Despite the ability of current methods to deal with many differ[...]

Because a structure's modal parameters (natural frequencies and mode shapes) are affected by structural damage, finite- element model updating techniques are often applied to locate and quantify structural damage. However, the dynamic behavior o[...]

The stability of a pair of line vortices is considered. The two line vortices are different in strength of circulation and can be counter- or corotating. This work is a generalization reported by Crow in 1970 and Jimenez in 1975. We find that th[...]
