A heterogeneous crowd evacuation model integrating multi-dimensional panic emotion characteristics

Journal of Physics: Complexity
In emergency evacuation scenes, environmental uncertainties and information deficits often trigger panic among individuals, which in turn impairs their ability to make sound judgments and decisions.

Improved Multi-Agent Reinforcement Learning for Path Planning-Based Crowd Simulation

IEEE Access, 2019
The combination of multi-agent technology and reinforcement learning methods has been recognized as an effective way which is used in path planning-based crowd simulation. However, the existing solution is still not satisfactory due to the problem in the

System Issues in Multi-agent Simulation of Large Crowds

, 2007
Crowd simulation is a complex and challenging domain. Crowds demonstrate many complex behaviours and are consequently difficult to model for realistic simulation systems.

Interpretability and Representability of Commutative Algebra, Algebraic Topology, and Topological Spectral Theory for Real‐World Data

Advanced Intelligent Discovery, EarlyView.
This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...

Diversified Crowd Evacuation Method in Large Public Places

IEEE Access, 2019
Realistic crowd simulation is an important issue for crowd management, public space design, and architectural and urban planning. In this paper, we present a novel approach for planning and directing heterogeneous large-scale crowd in public places.

The Insistence of Blackness and the Persistence of Antiblackness in Ireland

Australian Journal of Social Issues, EarlyView.
ABSTRACT This paper positions Ireland as a critical site for examining the insistence of blackness and an antiblackness created and sustained through Irish ethnonationalist imaginaries and exclusionary processes. Drawing on connected sociologies and Irish Black Studies, this enquiry argues that antiblackness in Ireland operates as a generational force,

Metformin enhances external urethral sphincter integrity and restores continence via AMPK activation in a rat model of stress urinary incontinence

Animal Models and Experimental Medicine, EarlyView.
The pathogenesis of stress urinary incontinence (SUI) is intimately associated with injury to the external urethral sphincter (EUS). In this study, we established an SUI model induced by double vaginal distension and demonstrated that metformin treatment activated the AMPK signaling in the EUS tissue.

Strategies in crowd and crowd structure

, 2012
In an emergency situation, imitation of strategies of neighbours can lead to an order-disorder phase transition, where spatial clusters of pedestrians adopt the same strategy.

A crowd team evacuation model considering spring effect

Developments in the Built Environment
In order to effectively describe the interaction between individuals in the team during the evacuation process, this paper introduces a spring force into the social force model to characterize the elastic and attractive force effects generated by team ...
