The tunnel lighting control system is designed based on “Guidelines for Design of Lighting of Highway Tunnels (China)” (JTG/T D70/2-01-2014). Firstly, when the approach of a vehicle is detected by the vehicle dete
Ventilation for subway stations with adjustable platform doors created by train-induced unsteady airflow Xin Zhang, Jiangyan Ma, Angui Li, Wenchao Lv, Wenrong Zhang, Dehui Li a School of Building Services Science and Engineering, Xian University of Architecture and Technology, Xian, Shaanxi, 710055, China b China Railway First Survey and Design Institute Group LTD, Xian, Shaanxi, 710043, China A R T I C L E I N F O Keywords: Subway station Adjustable platform doors Train-induced unsteady airflow Air inflow rate IDA tunnel A B S T R A C T At present, subways (rail transit) are undergoing rapid developments worldwide accompanied by massive energy consumption. Train-induced unsteady airflow (TIUA) generates airflow through the entrances and platform doors, which affects the ventilation and thermal environment of subway stations. Adjustable platform door systems are increasingly being installed in subway stations to reduce the energy cons
Single-Chip Design for Intelligent Surveillance System Tsung-Han Tsai , Member, IEEE, and Shih-Wei Chen Abstract— During recent years, a digital surveillance system has gained more popularity. Object recognition plays a critical role in an intelligent surveillance system. It mainly consists of several vision-based techniques such as segmentation and tracking. However, these techniques are still challenging. In this paper, an intelligent surveillance system has been proposed on the basis of single-chip design. An algorithm development and its hardware implementation are well addressed. Our algorithm accomplishes tracking of moving people through successive frames without using boundary box of object or color cues. Although there is occlusion due to gathering of people and other foreground objects, still the proposed algorithm can deal with such situations. The developed hardware architecture involves several tasks including foreground detection, sliced connected compone

英语原文共 7 页, 基于WiFi信道状态信息的行为识别综述 Siamak Yousefi, Hirokazu Narui, Sankalp Dayal, Stefano Ermon, and Shahrokh Valaee 摘要 本文综述了利用商业WiFi系统的信道状态信息(CSI)进行室内人行为识别的研究进展。人体各部分的运动引起无线信号反射的变化,从而导致CSI的变化。通过分析不同活动的CSI数据流,并将其与存储的模型进行比较,从而可以识别出人类的行为。这是通过从CSI数据流中提取特征,并使用机器学习技术来构建模型和分类器来实现的。本文所介绍的技术具有很好的性能,但是,我们建议使用诸如长-短期记忆(LSTM)递归神经网络(RNN)等深度学习技术来代替这些工作中使用的机器学习技术,并显示出改进的性能。我们还讨论了环境变化、帧速率选择和多用户场景等不同的挑战,最后提出了未来工作的可能方向

INTRODUCTION A character that marks the twenty-first century is the emergence of a general awareness and understanding of the importance of sustainable development in the society. This concern becomes important and can not be avoided in the construction industry. The extreme climate change and degradation of environmental quality also arise due to the exploitation of natural resources in order to fulfill people needs for residential space. The process of building construction could lead to such negative impacts on the environment both in and around the residence.Over time, the term 'green' is used interchangeably with the concept of 'sustainability', which means that human‟s co
