We modeled and applied Stochastic COntext Tree (SCOT) for statistical inference about financial, literary and seismological stationary strings. We analyzed several models viewed as simplified approaches to financial modeling: evaluate their stationary distribution, entropy rate and convergence to the Brownian motion. We also estimated the SCOT parameters and tested homogeneity of data strings u...

Models of α Cen A & B have been computed using the masses determined by Pourbaix et al. (2002) and the data derived from the spectroscopic analysis of Neuforge and Magain (1997). The seismological data obtained by Bouchy and Carrier (2001, 2002) do help improve our knowledge of the evolutionary status of the system. All the constraints are satisfied with a model which gives an age of about 6 Gy...

In recent years surface waves have found wide applications in various seismological studies of a very different scale. We present a brief description of our recent results in regional surface wave tomography of continents, in applying these results for nuclear tests monitoring purposes, and in studying shear-velocity structure of soft sediments below sea bottom. 4:20–4:50 Edo Nyland Univ. of Al...

THE recent organization by the American Geophys-ical Union of two cooperative committees of national scope, the Special Committee on the Geophysical and Geological Study of Ocean Basins, under the chair-manship of Professor R. M. Field, and the Special Committee on the Geophysical and Geological Study of Continents, under Professor W. T. Thom, points unmistakably to a growing realization of the...
