Crowd behavior analysis is an interdisciplinary topic. Understanding the collective crowd behaviors is one of the fundamental problems both in social science and natural science. Research of crowd behavior analysis can lead to a lot of critical applications, such as intelligent video surveillance, crowd abnormal detection, and public facility optimization. In this thesis, we study the crowd beh...

The design of an autonomous robot should start from the available hardware where microelectronics is just a part of a more complex architecture. The complementary rôles of electrical and mechanical devices are such that the latter cannot be ignored at all, as it has usually made in the world of computers, because the interactions between the physical components of the robot are not neglectable....

Similarly to evolving controllers for single robots also controllers for groups of robots can be generated by applying evolutionary algorithms. Usually a fitness function rewards desired behavioral features. Here we investigate an alternative method that generates collective behaviors almost only as a by-product. We roughly follow the idea of Helmholtz that perception is a process based on prob...

The network paradigm is used to gain insight into the structural root causes of the resilience of consensus in dynamic collective behaviors, and to analyze the controllability of the swarm dynamics. Here we devise the dynamic signaling network which is the information transfer channel underpinning the swarm dynamics of the directed interagent connectivity based on a topological neighborhood of ...

W ith the rise of social media, information sharing has been democratized. As a result, users are given opportunities to exhibit different behaviors such as sharing, posting, liking, commenting, and befriending conveniently and on a daily basis. By analyzing behaviors observed on social media, we can categorize these behaviors into individual and collective behavior. Individual behavior is exhi...

Spatial self-organizations appear in many natural and artificial systems. Spatial systems creation and development, called morphogenesis, is the subject of many research studies since many years (1). Fractal computation approach is, for exemple, one of the methods proposed to deal with such studies. But, even if this method is able to describe unlimited local formations on multi-scale descripti...

A burgeoning body of cultural coping research has begun to identify the prevalence and the functional importance of collective coping behaviors among culturally diverse populations in North America and internationally. These emerging findings are highly significant as they evidence culture's impacts on the stress-coping process via collectivistic values and orientation. They provide a critical ...

According to experts, the inefficient agricultural sector has a dominant role in degrading water resources all over the world. Farmers’ conservational behavior is an important aspect of new integrated water management studies. Relevantly, various behavioral theories have been proposed in the field of environmental psychology. The main objective of the present comparative analysis and review stu...

In response to an extreme event, individuals on social media demonstrate interesting behaviors in information seeking and sharing, depending on their backgrounds. Existing studies have attempted to analyze and understand the regularities of human responses during an extreme event, e.g., their spatiotemporal patterns. However, most of them focus on the general patterns of human collective online...
