Many physiologic functions fluctuate with time and the wave forms vary in complexity. Simple waves, such as the peripheral pulse, present no serious problem in analysis. When, however, the wave form is complex in appearance, existing analytic methods do not yield precise information. The general similarity between complex physiologic wave patterns and communication signals, such as sound waves,...

<p style='text-indent:20px;'>This paper deals with the random wave equation on a bounded domain Dirichlet boundary conditions. Randomness arises from velocity wave, which is positive variable, and two initial conditions, are regular stochastic processes. The aleatory nature of inputs mainly justified data errors when modeling motion vibrating string. Uncertainty propagated these to output...

Wave interference leads to deviations from the diffusive description of wave propagation through a random medium. This is a manifestation of an onset of Anderson localization – a paradigm in mesoscopic physics [1–3]. Self-consistent theory (SCT) of localization [4,5] accounts for the wave interference effects by renormalizing (reducing) the diffusion coefficient. In an experiment, one deals wit...
