An improved equivalent viscosity model for the bubbly oil under high shear rate
Shear-thinning effect of pure oil and distribution of bubble size are essential factors affecting the viscosity of bubbly oil. This study aims to establish an improved equivalent viscosity model for bubbly oil by considering the shear-thinning effect and

INCOME DISTRIBUTION BY AGE GROUP AND PRODUCTIVE BUBBLES [PDF]
The aim of this paper is to study the role of the distribution of income by age group on the existence of speculative bubbles. A crucial question is whether this distribution may promote a bubble associated to a larger level of capital, that is a productive bubble.

Inversion of Volume Scattering Function for Estimation of Bubble Size Distribution in Ocean Waters
Angular distribution of the intensity of light scattered by a spherical air bubble in the oceanic medium is distinctive near the critical scattering angle region, when light interacts with a bubble with a refractive index less than its surrounding medium.

On the Distribution of Bubbles of the Brownian Sheet
Let \(W\) be a real-valued two-parameter Brownian sheet. A set \(B \subset R^2_+\) is called a bubble if the interior of \(B\) is nonempty, \(W(s,t) = 0\) for \((s,t) \in \partial B\) and \(|W(s,t) |> 0\) for \((s,t) \in \text{int }B\). Let \(N(t,h)\) be the total number of bubbles of \(W\) in \([0,t]^2\), whose maximum height is greater than \(h\). It
