为了感谢惠俊英老师的谆谆教诲，再为好奇诸君奉上水声物理--海洋传播声场模拟的一份武林秘籍--海洋传播声场抛物方程解算方法--RAM！ 当好奇诸君阅毕此卷，再对照轻松跑完作业，即入门 RAM！ RAM 与 AcousticsToolbox 遵照 GNU 公共许可证进行分发。感谢Michael D. Collins 对 RAM 的原创，也感谢由 Free Software 凝聚起来的自由科学家社区(In order to thank Professor Hui Junying for his teachings, and then offer you a secret book of underwater acoustic physics, ocean propagation sound field simulation, the parabolic equation solution method of ocean propagation sound field, RAM! When curious gentlemen read this volume, and then compared with easy running homework, that is, access to RAM! RAM and Acoustics Toolbox are distributed under the GNU Public License. Thanks to Michael D. Collins for his original RAM and to the Free Software community of free scientists.)

利用蒙特卡洛的方法进行威布尔参数估计，随机生成对应参数估计值，不断迭代达到需要精度(Weibull parameter estimation using Monte Carlo method.)

说明：  通过matlab实现地震剖面、单炮记录、道集等地震数据的成像和成图(Imaging and mapping of seismic data such as seismic profile, single shot record and trace set by MATLAB)

使用白塞尔方法进行大地主题解算，正算由大地线和大地方位角计算经纬度，反算有经纬度计算大地线长度和大地方位角(Using the white Searl method to solve the geodetic problem, we calculate the longitude and latitude by the geodesic and the earth azimuth, and calculate the geodesic length and the large local angle by calculating the longitude and latitude)

说明：  神经肌肉电刺激信号采集与处理本科毕业设计(Neuromuscular electrical stimulation signal acquisition and processing Graduation Project)

以江苏丰县为例，展示了城区基准地价更新监测系统。 需要自行添加使用区域地价数据库（ArcGIS制作）。(Taking Jiangsu Fengxian County as an example, shows the monitoring system of the urban standard land price update. Need to add the use of regional land database (ArcGIS).)

ansys流固耦合双向分析，全自动脚本程序(ANSYS fluid solid coupling bidirectional analysis, automatic script program)

seam carving for image resizing

Morphological transformations are some simple operations based on the image shape. It is normally performed on binary images. It needs two inputs, one is our original image, second one is called structuring element or kernel which decides the nature of operation.
