The purpose of this paper is to point out that an asymptotic rule A+B/u for the ultimate ruin probability applies to a wide class of dependent risk processes, in continuous or discrete time. That dependence is incorporated through a mixing model in the individual claim amount distributions. Several special mixing distributions are examined in detail and some close-form formulas are derived. Cla...

Direct Monte Carlo simulation of internal energies of departure for binary mixtures of geological interest are gathered and compared to those calculated using a linear mixing rule. Simulation results for gas–oil, oil–oil, and oil–water mixtures show that the linear mixing rule used in the Gibbs–Helmholtz Constrained (GHC) equation of state framework gives accurate approximations of binary mixtu...

We present the computation of effective refractive coefficients for inhomogeneous two-component grains with 3 kinds of inclusions with mincl = 3.0 + 4.0i, 2.0 + 1.0i, 2.5 + 0.0001i and a matrix with mm = 1.33 + 0.01i for 11 volume fractions of inclusions from 0% to 50% and wavelengths λ=0.5, 1.0, 2.0 and 5.0 μm. The coefficients of extinction for these grains have been computed using a discrete...

Thus far, the measurement of dielectric properties of biological tissues has been achieved on the assumption that the biological tissues are homogeneous. In fact, most tissues should be heterogeneous because there are many small structures included in these tissues, such as blood vessel, nerve fiber and so on. When the dielectric properties of these tissues are measured by conventional sensor, ...

We calculate the on-shell Σ-Λ mixing parameter θ with the method of QCD sum rule. Our result is θ(m Σ ) = (−)(0.5 ± 0.1) MeV. The electromagnetic interaction is not included.

Microwave remote sensing techniques are used, among others, for temporally and spatially highly-resolved observations of land-surface properties, e.g., for the management of agricultural productivity and water resource, as well as to improve the performances of numerical weather prediction and climate simulations with soil moisture data. In this context, the effective dielectric constant of the...

finding frequent patterns plays a key role in exploring association patterns, correlation, and many other interesting relationships that are applicable in tdb. several association rule mining algorithms such as apriori, fp-growth, and eclat have been proposed in the literature. fp-growth algorithm construct a tree structure from transaction database and recursively traverse this tree to extract...
