Modeling Ultra-High-Density Exposure and Evacuation Dynamics in a High-Density Urban Plaza: An Agent-Based Simulation Study of Guangzhou Huacheng Plaza

Buildings
High-density urban plazas hosting multi-session public events often experience pulsed inflows, prolonged crowd retention, and localized bottleneck congestion, creating crowd-safety risks that cannot be fully captured by static capacity or total ...

Deceleration in The Micro Traffic Model and Its Application to Simulation for Evacuation from Disaster Area [PDF]

, 2011
Referring to the Nagel–Schreckenberg’s (NaSch) model, we have studied the impact of agent and diligent driver into the micro traffic model in the case of evacuation. This study is attention to the deceleration that added in the micro traffic model.

A second-order sliding mode controller with integral barrier Lyapunov function for crowd density regulation

Journal of Engineering and Applied Science
Effective evacuation strategies are critical for preventing stampedes in large-scale, high-density crowd management. This paper develops a second-order sliding mode controller within a distributed parameter system to regulate crowd density toward a safe ...

A simulation model for crowd evacuation of fire emergency scenario [PDF]

, 2017
Human safety is an important issue when handling the crowd evacuation in order to avoid death and injuries. Human behavior changes from normal to panic behavior when they are in an emergency scenario such as building on fire.

Dicarboxymethyl Cellulose‐Based Mixed‐Matrix Membrane Adsorbers: Preparation, Characterization, and Protein Retention Performance

Journal of Applied Polymer Science, EarlyView.
Dicarboxymethyl cellulose is incorporated, for the first time, into a polyethersulfone membrane. The functional membranes are prepared using dimethyl isosorbide through combined non‐solvent and vapor‐induced phase separation. The resulting membranes exhibit porous structures and protein‐retention potential, highlighting the potential of this cellulose ...

Simulation of Evacuating Crowd Based on Deep Learning and Social Force Model

IEEE Access, 2019
It is always difficult to evacuate crowds in public places like subway stations. The traditional crowd behavior simulation models often ignore two important issues in crowd evacuation: pedestrian tracking and individual differences. To solve the problem,

Crowd Evacuation Model Based on Improved PSO Algorithm

, 2020
: Aiming at the poor local optimization ability and easy premature convergence of the particle swarm optimization (PSO) algorithm in evacuation simulation, a crowd evacuation model based on the improved PSO algorithm is proposed.

Comparative Performance of Poly(Vinyl Alcohol)/Chitosan Hydrogels Reinforced With Kraft Lignin and Kraft Lignin Nanoparticles

Journal of Applied Polymer Science, EarlyView.
The use of kraft lignin and kraft lignin nanoparticles in poly(vinyl alcohol)/chitosan hydrogels was comprehensively compared. The results showed that a higher loading of lignin nanoparticles than bulk kraft lignin could be incorporated while maintaining favorable hydrogel properties, leading to improved overall performance. ABSTRACT The development of
