A new method for real-time tsunami forecasting will provide NOAA’s Tsunami Warning Centers with forecast guidance tools during an actual tsunami event. PMEL has developed the methodology of combining… (More)

Tsunamis are an ever-present threat to lives and property along the coasts of most of the world's oceans. As the Sumatra tsunami of 26 December 2004 reminded the world, we must be more proactive in… (More)

In the aftermath of the 26 December, 2004 tsunami, several quantitative predictions of inundation for historic events were presented at international meetings differing substantially from the… (More)

We study the asymptotic behaviour of the following linear growthfragmentation equation B Btupt, xq ` B Bx ` xupt, xq ̆ `Bpxqupt, xq “ 4Bp2xqupt, 2xq, and prove that under fairly general assumptions… (More)

In this paper, we relate the coupling of Markov chains, at the basis of perfect sampling<lb>methods, with damage spreading, which captures the chaotic nature of stochastic dynamics.… (More)

Systems composed of hard objects in a continuum often show a tendency to order as the density is increased, but exact results on such systems are scarce. We consider a system of disks centred on… (More)

Abstract. The present paper discusses the diffusion approximation of the linear Boltzmann equation in cases where the collision frequency is not uniformly large in the spatial domain. Our results… (More)
