Large deviation results are given for a class of perturbed nonhomogeneous Markov chains on finite state space which formally includes some stochastic optimization algorithms. Specifically, let {Pn} be a sequence of transition matrices on a finite state space which converge to a limit transition matrix P . Let {Xn} be the associated nonhomogeneous Markov chain where Pn controls movement from tim...

Being equipped with a millimeter-wave radar allows a low-flying helicopter to sense the surroundings in real time, which significantly increases its safety. However, nonhomogeneous clutter environments, such as a multiple target situation and a clutter edge environment, can dramatically affect the radar signal detection performance. In order to improve the radar signal detection performance in ...

This study compares prices offered by multiple Internet retailers. This task is challenging because e-tailers cannot present their entire assortments to each consumer. Therefore, the quality of the product assortments presented by different e-tailers to each consumer is not directly comparable on an item-by-item basis, resulting in nonhomogeneous offerings across retailers. We further consider ...

We study a nonlocal parabolic equation with an irregular kernel coefficient to establish higher Hölder regularity under appropriate integrablilty on the nonhomogeneous terms and minimal assumption coefficient.

Several threshold values for predicting weaning outcome from mechanical ventilation have been proposed. These values, however, have been obtained in nonhomogeneous patient populations. The aim of the present study was to determine the threshold values in chronic obstructive pulmonary disease (COPD) patients and compare them to those reported for nonhomogeneous patient populations. The initial w...

A method for the calculation of elastic constants in $NVT$ ensamble using molecular dynamics (MD) simulation with a realistic many-body embedded-atom-model (EAM) potential is studied detail. It shown that, such MD simulations, evaluation robust and accurate because it gives tensor single which converges small number time steps particles. These results highlight applicability this (i) local nonh...

The process of diffusion admixture particles in a multiphase randomly nonhomogeneous body with spherical inclusions different materials commensurable volume fractions phases is investigated. According to the theory binary systems, mathematical model disposed radii constructed. dense packing spheres used modeling skeleton body. contact initial-boundary value problem reduced mass transfer equatio...

In this paper, we study nonhomogeneous wavelet systems which have close relations to the fast wavelet transform and homogeneous wavelet systems. We introduce and characterize a pair of frequency-based nonhomogeneous dual wavelet frames in the distribution space; the proposed notion enables us to completely separate the perfect reconstruction property of a wavelet system from its stability prope...
