This dissertation presents experiments that studied two gravity driven granular channel flows. The first experiment used magnetic resonance imaging to measure the density and displacement distribution...
A model for red blood cells in simulations of large-scale blood flows
red blood cells model simulations large-scale blood flows
font style='font-size:12px;'>
2011/8/11
Abstract: Red blood cells (RBCs) are an essential component of blood. A method to include the particulate nature of blood is introduced here with the goal of studying circulation in large-scale realis...

Voltage Collapse and ODE Approach to Power Flows: Analysis of a Feeder Line with Static Disorder in Consumption/Production
Voltage Collapse Consumption/Production Feeder Line Static Disorder
font style='font-size:12px;'>
2011/9/15
We consider a model of a distribution feeder connecting multiple loads to the sub-station. Voltage is controlled directly at the head of the line (sub-station), however,voltage anywhere further down t...
