A grouping approach based on non‐uniform binary grid partitioning for crowd evacuation simulation

Grouping Behaviour in AmI-Enabled Crowd Evacuation

Grouping behaviour occurs often in crowd evacuation. On the one hand, groups are needed for efficient evacuation. On the other hand, large uncontrolled groups (herds) may cause clogging and increase panic. The mechanisms of emergence of leaders and groups in complex socio-technical systems with intelligent technical components are not well understood. This paper presents the first attempt to un...

Human Relationship Modeling in Agent-Based Crowd Evacuation Simulation

Crowd evacuation simulations are becoming a tool to analyze and assess the safety of occupants in buildings. Agent-based simulation provides a platform on which to compute individual and collective behaviors that occur in crowds. We propose a human behavior model in evacuation based on the Belief-Desire-Intention (BDI) model and Helbing’s agent behavior model. Human relationships affect the sta...

On Grid Partitioning for a High Performance Groundwater Simulation Software

The partitioning of a discretized computational domain is fundamental for solving many application problems on parallel high performance computer systems. This is also the key to work load balancing and minimizing communication overhead. This contribution focus on partitioning of real application problems for the parallel TOUGH2 software. TOUGH2 is a widely used reservoir simulator for solving ...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
