Discrete Element Method Modeling of an Extrusion Process with Recirculation for Dry Manufacturing of Lithium‐Ion Battery Electrodes

open access: yesBatteries &Supercaps, EarlyView.
On a digitized laboratory extruder, discrete element method modelling is studied, considering two classes of particles representing aggregates of 1) active material and 2) binder and carbon material is studied. Various extrusion scenarios leading to the formation of filaments devoted to the 3D printing of lithium‐ion battery electrodes are studied. The

Global and blowup solutions of quasilinear parabolic equation with critical Sobolev exponent and lower energy initial value

open access: yesJournal of Inequalities and Applications, 2001
In this paper, by means of the energy method, we first study the existence and asymptotic estimates of global solution of quasilinear parabolic equations involving -Laplacian and critical Sobolev exponent and lower energy initial value in a bounded ...

Asymptotic Formulas for Some Arithmetic Functions [PDF]

open access: yesCanadian Mathematical Bulletin, 1958
Let f(x) be an increasing function. Recently there have been several papers which proved that under fairly general conditions on f(x) the density of integers n for which (n, f(n)) = 1 is 6/π2 and that (d(n) denotes the number of divisors of n)In particular both of these results hold if f(x) = xα, 0 < α < 1 and the first holds if f(x) = [α x], α ...

Existence, Uniqueness and Asymptotic Behavior of Solutions for Semilinear Elliptic Equations

open access: yesMathematics
A class of semilinear elliptic differential equations was investigated in this study. By constructing the inverse function, using the method of upper and lower solutions and the principle of comparison, the existence of the maximum positive solution and ...

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

Asymptotic Formula for the Moments of Lebesgue’s Singular Function

open access: yesМоделирование и анализ информационных систем, 2015
Recall Lebesgue’s singular function. Imagine flipping a biased coin with probability p of heads and probability q = 1 − p of tails. Let the binary expansion of ξ ∈ [0, 1]: ξ = ∑∞ k=1 ck2−k be determined by flipping the coin infinitely many times, that is ...

Restricted Tweedie stochastic block models

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.
