We presented our work on optimized particle-based computational simulation at the ICHMT International Symposium on Advances in Computational Heat Transfer (CHT), Piscataway, NJ. We present an optimized particle-based computational method for studying kinetics, computing nucleation rate, and analyzing mechanism of both homogeneous and heterogeneous bubble nucleation. As a rare event, bubble nucleation is difficult to study with traditional computa
During January 11-14, we presented our work on understanding and improving urban mobility at the Transportation Research Board (TRB) 94th Annual Meeting in the Walter E. Washington Convention Center, Washington, DC. An empirical study of combining participatory and physical sensing to better understand and improve urban mobility networks. Transportation Research Board (TRB) Annual Meeting, Washington, DC, USA, 2015. An unsupervised learning appro
On October 10, Dr. Xie presented the work on multimodal urban traffic control at the 2014 IEEE International Conference on Intelligent Transportation Systems, Qingdao, China. This work extends our decentralized, schedule-driven approach to traffic network control in the direction of a broader mobility objective to optimize all modes of traffic that are central to sustainable urban living. We focus specifically on accommodating pedestrians and opt
On Aug 11-12, we attended Workshop on Big Data and Urban Informatics, with support from the National Science Foundation, held at the University of Illinois at Chicago (UIC). “The workshop brought together researchers from diverse disciplines motivated by sustainability and social equity concerns, the need for efficient resource management, and a desire to leverage technological developments that have the potential to provide solutions to th
Presented the work on tackling real-world changes and the integration with a unified route choice framework for the smart and scalable urban traffic control system at the Transportation Research Board (TRB) Annual Meeting, Washington, DC.
We presented our poster on the initial smart and scalable urban traffic control (SURTRAC) system at the Transportation Research Board (TRB) Annual Meeting, Washington, DC. SURTRAC is a packing box encapsulating the core control engine, including schedule-driven intersection control (SchIC) and decentralized coordination mechanisms, with some strengthening strategies to enable its real-world operations.
We presented the work on coordinated look-ahead scheduling for smart and scalable urban traffic control in the 2012 International Joint Conference on Autonomous Agents and Multiagent Systems (AAMAS), at the Polytechnic University of Valencia, Spain. The work is a real-time, smart and scalable, adaptive traffic signal control system that optimizes the highly dynamic traffic flow in complex (grid-like) urban road networks. Its core control engine i
Dr. Xie presented the paper on platoon-based adaptive traffic signal control for 2011 Annual IEEE ITS conference at Cafritz Conference Center, The George Washington University, Washington DC. We take a self-scheduling approach to solving the traffic signal control problem, where each intersection is controlled by a self-interested agent operating with a limited (fixed horizon) view of incoming traffic. Central to the approach is a representation

Our Co-Founder, Dr. Wang, gave an academic report at Dalian Institute of Chemical Physics, Chinese Academy of Sciences. Title: Multi-scale solvent-free coarse-grained modeling of lipid bilayer membranes: from top-down to systematic scheme Abstract: This talk will focus on the implicit solvent coarse-grained (CG) modeling of lipid bilayer membranes. Starting from an introduction on my three-bead solvent-free CG membrane model developed in the top-
