Motion of a ball rolled over a shallow step

Keith Zengel, Laruen Boehnert

A ball rolled over a shallow step will experience an increase in velocity along the direction perpendicular to the step. This causes a deflection in the ball's trajectory. In this…

The Bat Signal

Keith Zengel, Anna Klales

We present a simple experiment that can be run in class or remotely with minimal materials. Students use the principles of geometric optics to create their own versions of the bat…

A monotone finite element method for an elliptic distributed optimal control problem with a convection-dominated state equation

SeongHee Jeong, Seulip Lee, Sijing Liu

We propose and analyze a monotone finite element method for an elliptic distributed optimal control problem constrained by a convection-diffusion-reaction equation in the convectio…

Finite Populations & Finite Time: The Non-Gaussianity of a Gravitational Wave Background

William G. Lamb, Jeremy M. Wachter, Andrea Mitridate +5

Strong evidence for an isotropic, Gaussian gravitational wave background (GWB) has been found by multiple pulsar timing arrays (PTAs). The GWB is expected to be sourced by a finite…

A weak Galerkin method with preconditioning for constrained optimal control problems with general tracking

SeongHee Jeong, Seulip Lee, Kening Wang

This paper presents a weak Galerkin (-WG) method combined with an additive Schwarz preconditioner for solving optimal control problems (OCPs) governed by partial differe…

An Undergraduate Consortium for Addressing the Leaky Pipeline to Computing Research

James Boerkoel, Mehmet Ergezer

Despite an increasing number of successful interventions designed to broaden participation in computing research, there is still significant attrition among historically marginaliz…
