在采用差频接收下的二维RMA算法仿真程序(The simulation program of two dimensional RMA algorithm based on differential frequency reception)

说明：  维纳滤波算法，可以实现对语音信号的降噪，效果还可以(Wiener filtering algorithm, it can achieve noise reduction on speech signals)

极值理论POT模型阈值选取，matlab代码。(POT model; extreme value theory)

说明：  这是一个关于二维的卡尔曼滤波跟踪的代码，很简单的C语言编程，运动的是匀速运动模型。(Kalamn tracking code)

为了感谢惠俊英老师的谆谆教诲，特为好奇诸君再奉上水声物理--海洋传播声场模拟的一份武林秘籍！ 当好奇诸君阅毕此卷，又轻松跑完9份作业（9路招式），即悟简正波海洋声场传播模型之能耐！ KRAKEN与AcousticsToolbox遵照GNU公共许可证进行分发。感谢Michael B. Porter对KRAKEN的原创。也感谢由Free Software凝聚起来的自由科学家社区。 本秘籍适合大三以上和非水声物理专业同志们的快速参学。 吴开明 2018.12(The KRAKEN model was initially developed as a research code to evaluate new algorithms. As such it required numerous modifications to be usable as a production code. This work was begun at the Naval Ocean Systems Center and continued at the Naval Research Laboratory in support of the research on matched-field processing.)

描述了形状记忆合金的超弹性，载荷为循环载荷(Describes the superelasticity of shape memory alloys)

说明：  通过两点法 计算水波的反射系数 海洋工程领域实用代码(The reflection coefficient calculation by two points method. Useful code for ocean engineering.)

可以计算临界转速，书上的一个例子，可以看看(Calculating Critical Speed)

绘制双层各向异性介质AVO曲线，可以更改介质类型(Drawing the AVO curve of anisotropic medium,the type of medium can be changed.)

说明：  基于matpower 的最小网损最优潮流解(Optimal power flow solution with minimum network loss based on MatPower)
