Recently, Raducan et al. (2014a) obtained recursive formulas for the ruin probabilityof a risk process at or before claim instants under the assumptions that the claim sizesare independent, nonhomogeneous Erlang distributed, and independent of the inter-claimtimes (i.e., the times between two successive claims), which were assumed to be inde-pendent, identically distributed (i.i...

We investigates the performance of movement-based location update in multitier wireless networks with sparsely correlated low-tier microcells. The topologies are considered to have random overlays of different microcell cluster sizes, with distributions spatially of two forms: homogeneous and nonhomogeneous. Permission for a mobile station (MS) to report to either a low-tier microcell or a high...

The material parameters (area stretch modulus and bending rigidity) of two-component amphiphilic membranes are determined from dissipative particle dynamics simulations. The preferred area per molecule for each species is varied so as to produce homogeneous mixtures or nonhomogeneous mixtures that form domains. If the latter mixtures are composed of amphiphiles with the same tail length, but di...

Studying the interaction between brain regions is important to increase our understanding of brain function. Magnetoencephalography (MEG) is well suited to investigate brain connectivity, because it provides measurements of activity of the whole brain at very high temporal resolution. Typically, brain activity is reconstructed from the sensor recordings with an inverse method such as a beamform...

A set of easily verifiable sufficient conditions are derived for the existence of a positive (componentwise) solution of a linear nonhomogeneous system of equations in which the coefficient matrix can be partitioned into submatrices with positive elements.

We show that the two dimensional Navier–Stokes equations in the stream function and vorticity form with nonhomogeneous boundary conditions have a unique solution with a stream function having two space derivatives. 2005 Published by Elsevier Inc.

In this paper we obtain oscillation criteria for solutions of homogeneous and nonhomogeneous cases of second order neutral differential equations with positive and negative coefficients. Our results improve and extend the results of Manojlović, Shoukaku, Tanigawa and Yoshida [6].
