International audience; Traffic waves are phenomena that emerge when the vehicular density exceeds a critical threshold. Considering the presence of increasingly automated vehicles in the traffic stream, a number of research activities have focused o

Publikováno v: ICCPS

In this paper we describe an experience report and field deployment of real-time filtering algorithms used with a robotic vehicle to smooth emergent traffic waves. When smoothing these waves in simulation, a common approach is to implement controller

Particle methods for PDEs arising in financial modeling

Autor: Shumo Cui, Alexander Kurganov, Alexei Medovikov

Publikováno v: Applied Numerical Mathematics. 93:123-139

We numerically study convection-diffusion equations arising in financial modeling. We focus on the convection-dominated cases, in which the diffusion coefficients are relatively small. Both finite-difference and Monte-Carlo methods which are widely u

Steady State and Sign Preserving Semi-Implicit Runge--Kutta Methods for ODEs with Stiff Damping Term

Autor: Alina Chertock, Tong Wu, Alexander Kurganov, Shumo Cui

Publikováno v: SIAM Journal on Numerical Analysis. 53:2008-2029

In this paper, we develop a family of second-order semi-implicit time integration methods for systems of ordinary differential equations (ODEs) with stiff damping term. The important feature of the new methods resides in the fact that they are capabl
