Blind spot detection using vision for automotive applications

This paper describes a vision-based system for blind spot detection （BSD） in intelligent vehicle applications. A camera is mounted in the lateral mirror of a car with the intention of visually detecting cars that are located in the so-called blind spot and cannot be perceived by the vehicle driver. The detection of cars in the blind spot is carried out using computer vision techniques, based on optical flow and a double-stage data clustering technique for robust vehicle detection.     

Zero-voltage switching converter absorbing parasitic parameters for super high frequency induction heating

This paper presents a novel mega-Hz-level super high frequency zero-voltage soft-switching converter for induction heating power supplies. The prominent advantage of this topology is that it can absorb both inductive and capacitive parasitic components in the converter. The switch devices operate in a zero-voltage soft-switching mode. Consequently, the high voltage and high current spikes caused by parasitic inductors or capacitors oscillation do not occur in this circuit, and the high power loss caused by high frequency switching can be greatly reduced. A large value inductor is adopted between the input capacitor and the switches, thus, this novel converter shares the benefits of both voltage-type and current-type circuits simultaneously, and there are no needs of dead time between two switches. The working principles in different modes are introduced. Results of simulation and experiments operated at around 1 MHz frequency verify the validity of parasitic components absorption and show that this convener is competent for super high frequency applications.     

Exact solutions for different vorticity functions of couple stress fluids

In this paper, inverse solutions are obtained for the class of 2D steady incompressible couple stress fluid flows. This class consists of flows for which the vorticity distribution is given by △^2ψ=ψ＋f（x,y）. The solutions are obtained by applying the inverse method, which makes certain hypotheses regarding the form of the velocity field and pressure but without making any regarding the boundaries of the domain occupied by the fluid. Inverse solutions are derived for three different forms of f（x,y）.     

关于高三考生普通高校招生考试法律意识的调查研究

本文对北京、上海、杭州、重庆以及厦门等地部分高三学生进行了有关普通高校招生考试法律意识的问卷调查,分析了当前我国考生法律意识、权利意识的现状。文章认为,当前我国考生的法律意识普遍偏低,并呈现出一定的层次性、矛盾性。为此,作者提出了具体的对策。     

普通高中学生职业生涯规划的调查研究——以徐州市区普通高中为例

随着目前就业压力的加剧,高中生职业生涯规划的必要性日益凸显。通过对徐州市城区普通高中学生职业生涯规划的调查显示,高中生的职业生涯规划在学校、年级、专业、性别上存在着差异;高中生存在对自我缺乏了解,对职业和社会缺乏认识,职业或专业目标模糊,规划的行动力不足,职业价值取向偏颇;缺乏规划的正确方法等问题。

基于SOLO分类理论的普通高中学业水平等级考试试题能力结构研究——以2020年北京、天津、山东、海南四省市化学试题为例

依据SOLO分类理论对2020年实施新高考的北京、天津、山东、海南四省市普通高中学业水平等级考试化学试题的能力结构进行比较分析,探查试题的命制特点和规律。研究发现:2020年四省市化学试题在SOLO各结构水平层次上均有涉及,多元结构水平和关联结构水平试题占比较高,体现了试题的选拔性;试题中各知识模块的SOLO结构水平层次分布整体均衡,试题内容全面,注重对基础知识的考查,体现了试题的基础性。为了进一步优化化学课堂教学、促进学生全面发展,中学化学教师可以从以下几个方面着手:对标学业质量标准,统筹规划教学的深度与广度;重视实际问题解决,加强学科素养和关键能力的培养;加强教学情境创设,重视创新意识和迁移应用能力的培养;优化课堂教学设计,重视学生高阶思维能力的培养。
