收藏China Health and Nutrition Survey (CHNS)
China Health and Nutrition Survey(CHNS)是一项由美国北卡罗来纳大学人口中心与中国疾病预防控制中心营养与健康所合作开展的长期开放性队列研究项目,旨在评估国家和地方政府的健康、营养与家庭计划政策对人群健康和营养状况的影响,以及社会经济转型对居民健康行为和健康结果的作用。该调查覆盖中国15个省份和直辖市的约7200户家庭、超过30000名个体,采用多阶段随机抽样方法,收集了家庭、个体以及社区层面的详细数据,包括饮食、健康、经济和社会因素等信息。自2011年起,CHNS不断扩展,新增多个城市和省份,并持续完善纵向数据链接,为研究中国社会经济变化与健康营养的动态关系提供了重要的数据支持。

Simulation of rear wheel steering in a vehicle towing a single axle trailer with variable load distribution
This is the dataset for a publication on the stability of automotive vehicles when towing single axle trailers. The loading of the trailer is critical for stability, if the load distribution is too far back, then the trailer will begin to sway uncontrollably, dictating the track of the vehicle.In this research, small proportional control of the rear wheel steering of a larger towing vehicle is shown to be able to further stabilize the system easily, thus improving the safety margin. This is based on control measurements of the yaw angle, either directly measured or inferred from rear camera / parking sensor measurements.The simulation environment is Simulink and all scripts are included to initialise and plot the results. The work is based on the built in example "Two axle vehicle towing one axle trailer" with modifications to enable control algorithms for rear wheel steering control and variable load distribution.
