Characterization of pedestrian contact interaction trajectories
Jaeyoung Kwak, Michael H. Lees, Wentong Cai
A spreading process can be observed when a particular behavior, substance, or disease spreads through a population over time in social and biological systems. It is widely believed…
Time-Efficient and High-Quality Graph Partitioning for Graph Dynamic Scaling
Masatoshi Hanai, Nikos Tziritas, Toyotaro Suzumura +2
The dynamic scaling of distributed computations plays an important role in the utilization of elastic computational resources, such as the cloud. It enables the provisioning and de…
Influence of committed volunteers on helping behavior in emergency evacuations
Jaeyoung Kwak, Michael H. Lees, Wentong Cai +2
We study how the presence of committed volunteers influences the collective helping behavior in emergency evacuation scenarios. In this study, committed volunteers do not change th…
Modeling Helping Behavior in Emergency Evacuations Using Volunteer's Dilemma Game
Jaeyoung Kwak, Michael H Lees, Wentong Cai +1
People often help others who are in trouble, especially in emergency evacuation situations. For instance, during the 2005 London bombings, it was reported that evacuees helped inju…
Estimating horizontal movement performance of patient beds and the impact on emergency evacuation time
Jaeyoung Kwak, Michael H. Lees, Wentong Cai +2
Emergency evacuation of patients from a hospital can be challenging in the event of a fire. Most emergency evacuation studies are based on the assumption that pedestrians are ambul…
Distributed Edge Partitioning for Trillion-edge Graphs
Masatoshi Hanai, Toyotaro Suzumura, Wen Jun Tan +3
We propose Distributed Neighbor Expansion (Distributed NE), a parallel and distributed graph partitioning method that can scale to trillion-edge graphs while providing high partiti…
A Survey on Agent-based Simulation using Hardware Accelerators
Jiajian Xiao, Philipp Andelfinger, David Eckhoff +2
Due to decelerating gains in single-core CPU performance, computationally expensive simulations are increasingly executed on highly parallel hardware platforms. Agent-based simulat…
