Driver fatigue detection based on computer vision is considered as one of the most hopeful applications of image recognition technology. The key issue is to extract and select useful features from the driver images. In this work, we use the properties of image sequences to describe states of drivers. In addition, we introduce a kernelized fuzzy rough sets based technique to evaluate quality of ...

To address the issues of insufficient danger excavation and long data collection period in traditional traffic risk assessment methods, this paper proposes a method based on driver’s improper driving behavior abnormal vehicle state warning data. Meanwhile, analyses built environment’s impact using spatial econometric model. Firstly, system with relative incidence (eye closure, yawn, looking awa...

Abstract Yawning is a complex behaviour linked to several physiological (e.g. drowsiness, arousal, thermoregulation) and social phenomena yawn contagion). Being yawning an evolutionary well-conserved, fixed action pattern widespread in vertebrates, it valuable candidate test hypotheses on its potential functions across the different taxa. The spotted hyaena ( Crocuta crocuta ), most cooperative...

In this paper we try to define the difference between hierarchical organization and selforganization. Organization is defined as a structure with a function. So we can define the difference between hierarchical organization and self-organization both on the structure as on the function. In the next two chapters these two definitions are given. For the structure we will use some existing definit...
