关于MATLAB Simulink方面的视频教学 拿出来和大家分享下 应该会有帮助的(MATLAB Simulink' s video on out and share teaching should be helpful under)

计算偶极子天线的辐射阻抗、输入阻抗、方向图等。(Calculated dipole antenna radiation resistance, input impedance, pattern and so on.)

在人们的生产活动和社会活动中常常会遇到这样的问题：经过一段时间之后，需要对具有相同类型的部门或单位（称为决策单元）进行评价，其评价的依据是决策单元的“输入”数据和“输出”数据，输入数据是指决策单元在某种活动中需要消耗的某些量，例如投入的资金总额，投入的总劳动力数，占地面积等等；输出数据是决策单元经过一定的输入之后，产生的表明该活动成效的某些信息量，例如不同类型的产品数量，产品的质量，经济效益等等．再具体些说，譬如在评价某城市的高等学校时，输入可以是学校的全年的资金，教职员工的总人数，教学用房的总面积，各类职称的教师人数等等；输出可以是培养博士研究生的人数，硕士研究生的人数，大学生的人数，学生的质量（德，智，体），教师的教学工作量，学校的科研成果（数量与质量)等等．根据输入数据和输出数据来评价决策单元的优劣，即所谓评价部门（或单位）间的相对有效性．(In people s productive activities and social activities often encounter such a problem: After a period of time, need to have the same type of departments or units (referred to as the decision-making unit) to evaluate the basis for his assessment in decision-making unit "input "Data and" output "data, input data refers to the decision-making unit in certain activities that need to consume certain amount of, for example, the total funds invested, the investment of the total workforce number, area, etc. output data through the decision-making unit After a certain input to produce the show the effectiveness of the activity of certain amount of information, such as different types of product quantity, product quality, economic efficiency and so on. Be more specific, said, for example, in evaluating a city s institutions of higher learning, the input can be the year the school funds, the total number of faculty, teaching a total area of space, all kinds of titles the number of teachers, etc)

这个是一个很详细的介绍了声学测量的内容和方法，是西工大的教学材料，希望对学习心理声学的同学有帮助。(This is a very detailed description of the acoustic measurement of the Neirong and the method is NPU teaching materials, Xi Wang students learning psychoacoustic help.)

估计光流的经典算法H&S，经测试可以使用。(Estimates the optical flow for standard test sequences using H&S algorithm)

Graph-Based Segmentation 是经典的图像分割算法，该算法是基于图的 贪心聚类 算法，实现简单，速度比较快，精度也还行。(Graph based Segmentation is a classical image Segmentation algorithms, the algorithm is Based on the figure of greedy clustering algorithm, speed is faster, and easy to implement precision is also ok.)

对于高斯脉冲信号，在光纤传输过程中需要考虑群速度色散和交叉相位调制(For the Gaussian pulse signal, in the optical fiber transmission process need to consider the group velocity dispersion and cross phase modulation)

说明：  中值滤波是图像预处理中的一种较常用的方法， 它能有效去除椒盐噪声等的影响。(The median filter is the image preprocessing of a more common method, it can effectively remove the impact of salt and pepper noise.)
