Biofilms in porous media: development of macroscopic transport equations via volume averaging with closure for local mass equilibrium conditions [PDF]
, 2009 In this work, we upscale a pore-scale description of mass transport in a porous medium containing biofilm to develop the relevant Darcy-scale equations.

Features of Oscillations in Adiabatic Oscillators with Delay
Моделирование и анализ информационных систем, 2013 In this paper, we describe the features of oscillations in adiabatic oscillators when the delay is introduced into the equation. We give a short description of the method of asymptotic integration of one class of linear delay differential systems in the ...

Convergence of the Generalized Volume Averaging Method on a Convection-Diffusion Problem: A Spectral Perspective [PDF]
, 2005 A mixed formulation is proposed and analyzed mathematically for coupled convection-diffusion in heterogeneous medias. Transfer in solid parts driven by pure diffusion is coupled with convection-diffusion transfer in fluid parts.

Averaging Methods for Second-Order Differential Equations and Their Application for Impact Systems
Mathematics, 2020 In this paper, we discuss the averaging method for periodic systems of second order and the behavior of solutions that intersect a hyperplane. We prove an averaging theorem for impact systems.

Finding the Optimal Multimodel Averaging Method for Global Hydrological Simulations
Remote Sensing, 2021 Global gridded precipitations have been extensively considered as the input of hydrological models for runoff simulations around the world. However, the limitations of hydrologic models and the inaccuracies of the precipitation datasets could result in ...

A method to average immunofluorescent histograms [PDF]
Cytometry, 1986 AbstractSingle parameter gated flow cytometric fluorescent histograms were obtained on normal donor blood mononuclear cells using several commonly available lymphocyte surface markers. A computer method was developed to average single parameter flow cytometric immunofluorescent histograms.

Nihon Kikai Gakkai ronbunshu, 2019 Cycle-to-cycle variation (CCV) of in-cylinder flow occurs in internal combustion engines. It is necessary to analyze CCV of flow to separate averaged-flow (as low frequency / low wave number) from turbulence (as high frequency / high wave number ...

CT Volumetry of Convoluted Objects—A Simple Method Using Volume Averaging
Tomography, 2021 Accurate measurement of object volumes using computed tomography is often important but can be challenging, especially for finely convoluted objects with severe marginal blurring from volume averaging. We aimed to test the accuracy of a simple method for
