Autor: Heming Cheng, Jifeng Dai, Gen Li, Dongfang Ding, Jianyun Li, Ke Zhang, Liuchuang Wei, Jie Hou

Publikováno v: Frontiers in Physiology, Vol 15 (2024)

Introduction: Orthostatic hypotension (OH) is common among the older population. The mechanism hypothesized by OH as a risk factor for cognitive decline and dementia is repeated transient cerebral blood flow deficiency. However, to our knowledge, qua

Pedestrian Guiding Signs Optimization for Airport Terminal

Autor: Jianxin Lin, Rui Song, Jifeng Dai, Pengpeng Jiao

Publikováno v: Discrete Dynamics in Nature and Society, Vol 2014 (2014)

The pedestrian guiding sign (PGS) is used to lead people within the transportation terminal to their directions efficiently and without boundaries. In this paper, we aim to optimize the guiding signs for people in the comprehensive transportation ter
