Change-in-velocity detection for multidimensional data
Linh Do, Dat Do, Keisha J. Cook +2
In this work, we introduce CPLASS (Continuous Piecewise-Linear Approximation via Stochastic Search), an algorithm for detecting changes in velocity within multidimensional data. Th…
Source identification via pathwise gradient estimation
Richard B. Lehoucq, Scott A. McKinley, Petr PlecháÄ
In the context of PDE-constrained optimization theory, source identification problems traditionally entail particles emerging from an unknown source distribution inside a domain, m…
Inequality and Mobility in a Minimal Model for Evolving Income Distributions
Scott A. McKinley, Gary A. Hoover
In this paper we explore the dynamic relationship between income inequality and economic mobility through a pairing of a population-scale partial differential equation (PDE) model…
Considering experimental frame rates and robust segmentation analysis of piecewise-linear microparticle trajectories
Keisha J. Cook, Nathan Rayens, Linh Do +2
The movement of intracellular cargo transported by molecular motors is commonly marked by switches between directed motion and stationary pauses. The predominant measure for assess…
