Summary On many urban low‐grade or branch roads, especially in medium small cities China, bicyclists and motorists commonly share the non‐barrier road surface. Because bicycles are unpredictable unstable when moving, motorized vehicles must reduce their speed to safely approach overtake them. In this study, gradual deceleration process a vehicle undergoes before it passes bicycle was analyzed. The motorist assumed prefer comfortable select higher rate only distance insufficient car's...

Parallel perforation around the cigarette splicing paper has been used for sensory quality adjustment and dilution of smoke. Particularly, different sizes depths can significantly affect tar content in mainstream Therefore, accurate detection parameters is crucial ensuring product reducing damage to human health before processing completion. However, tiny size morphologies perforations (e.g., are extremely similar interference points) pose a great challenge identification three-dimensional...

Comments of online articles provide extended views and improve user engagement. Automatically making comments thus become a valuable functionality for forums, intelligent chatbots, etc. This paper proposes the new task automatic article commenting, introduces large-scale Chinese dataset with millions real human-annotated subset characterizing comments' varying quality. Incorporating human bias comment quality, we further develop metrics that generalize broad set popular reference-based...

Team interaction process contains three stages: input, and output. The effectiveness of team is the decisive factor competition. Nowadays, many scholars study on based a particular view, but few put up with an overview whole research results. Based predecessors' researches centered process, this paper outlines stages its elements, influence to performance measurements interaction. This also puts forward some prospects finally.

摘要: 针对车辆高速紧急工况下的主动避撞问题,提出一种基于工况辨识的自适应避撞控制策略。以实时交通环境信息与车辆状态信息为基础构建一种紧急工况避撞模式分类方法,该方法把紧急工况避撞模式分为制动避撞、转向避撞、协调避撞三种模式。对于制动避撞模式,设计一种考虑路面附着条件和驾乘人员舒适度的纵向制动避撞策略;对于转向操纵避撞模式,构建基于多项式路径规划的避撞策略;对于制动和转向协调避撞模式,设计一种基于数据驱动的自学习协调控制策略。不同控制策略的期望输出通过比例积分微分(Proportional integral differentiation, PID)下层控制器对期望值进行跟踪来完成避撞。在Matlab/Simulink环境中搭建Simulink-Carsim汽车紧急避撞控制联合仿真平台,基于该平台进行多种工况的虚拟试验来验证控制系统的实时性和有效性。结果表明,控制系统能自动有效识别当前紧急工况该采取何种避撞操纵,在完成避撞的同时也能保证车辆的稳定性。

Urban areas consume up to 80 percent of the world's total energy production and are growing in size complexity. At present, urban building consumption is largely considered solely terms individual types, neglecting effects residents’ location-based activities that influence patterns supply demand. Here, we examine spatial fluctuations these effects. A regression analysis 3,613,360 positional records containing human mobility data across 983 Greater London 801 City Chicago residential...

The interest in autonomous electrified vehicles has rapidly increased recent years.
