Sharp interfaces in two dimensional free boundary problems: Efficient interface calculation via matched conformal maps
Stuart Kent, Shankar C. Venkataramani
We use conformal maps to study a free boundary problem for a two-fluid electromechanical system, where the interface between the fluids is determined by the combined effects of ele…
Defining a Trend for a Time Series Which Makes Use of the Intrinsic Time-Scale Decomposition
Juan M. Restrepo, Shankar C. Venkataramani, Darin Comeau +1
We propose criteria that define a trend for time series with inherent multi-scale features. We call this trend the {\it tendency} of a time series. The tendency is defined empirica…
A scaling limit for the degree distribution in sublinear preferential attachment schemes
Jihyeok Choi, Sunder Sethuraman, Shankar C. Venkataramani
We consider a general class of preferential attachment schemes evolving by a reinforcement rule with respect to certain sublinear weights. In these schemes, which grow a random net…
