Unfair reputation systems, slow payments, lack of transparency, and socio-spatial inequalities are only some of the many reasons for conflicts in crowdsourcing. The divisive logic of the system and the sharing processes in the peer-community create interesting dynamics and new foci on old conflicts.

Learning Crowd Motion Dynamics with Crowds
Proceedings of the ACM on Computer Graphics and Interactive TechniquesReinforcement Learning (RL) has become a popular framework for learning desired behaviors for computational agents in graphics and games. In a multi-agent crowd, one major goal is for agents to avoid collisions while navigating in a dynamic environment.

Dynamic Crowd Routing: RL-Driven Crowd Dynamics
2024 IEEE 26th International Workshop on Multimedia Signal Processing (MMSP)The simulation of crowds is complex and challenging. Every individual in a crowd exhibits a different behaviour, targets a different goal, and undergoes different types of interactions. Within crowds, groups can be identified in both static and dynamic configurations, with varying levels of responsiveness, leading to the emergence of complex avoidance ...

An Introduction to the Modeling of Crowd Dynamics
2014In this chapter we begin the discussion about crowd dynamics from an informal phenomenological point of view. In particular, we put in evidence how simple interaction rules adopted independently by pedestrians generate, at a collective level, complex group behaviors featuring various forms of self-organization.

Molecular crowding and protein enzymatic dynamics
Physical Chemistry Chemical Physics, 2012The effects of molecular crowding on the enzymatic conformational dynamics and transport properties of adenylate kinase are investigated. This tridomain protein undergoes large scale hinge motions in the course of its enzymatic cycle and serves as prototype for the study of crowding effects on the cyclic conformational dynamics of proteins.

An Overview of the Modeling of Crowd Dynamics
2014In this chapter we review some of the most important models at microscopic, macroscopic, and mesoscopic scale, which, in our opinion, represent milestones in their respective fields or are of particular interest for this book. We also report some models for rational pedestrians, which make use of techniques from optimal control theory.

The impact of different obstacles on crowd dynamics
Journal of Computational Science, 2019Modification of space through the installation of obstacles is one way to control the flow of human crowds. Carefully placed obstacles coupled with existing architectural structures can be used to improve crowd safety at mass gatherings. Although this concept is well understood in the field of crowd dynamics, a systematic approach geared towards ...

Approaching humans in crowded and dynamic environments
2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2016This paper proposes an effective human approaching algorithm that enables a mobile service robot to safely and socially approach humans in dynamic and crowded environments. The proposed method is composed of two major functional blocks: (1) The approaching pose estimation (APE) is to estimate the approaching pose of both stationary and moving humans by

Dynamic implications of fiscal policy Crowding out or crowding in [PDF]
, 2003 The purpose of this paper is to analyze the short run and long run effects of fiscal policy. The classical-Harrodian model developed in Moudud (2000, 1999), which is an extension of Shaikh (1995, 1992, 1991), provides a demonstration of dynamic fiscal policy context. It asserts that the there is a crowding in of output growth in the short run.

Bilinear dynamics for crowd video analysis
Journal of Visual Communication and Image Representation, 2017Abstract In this paper, a novel crowd descriptor, termed as bilinear CD (Curl and Divergence) descriptor, is proposed based on the bilinear interaction of curl and divergence. Specifically, the curl and divergence activation maps are computed from the normalized average flow.
