dct
在一个图像块中调整两个(或多个) DCT系数的相对大小。将描述一个使用数字图像作为载体的系统。在编码处理中，发送者将载体图像分成8×8的像素块，每一块只精确地编码一个秘密信息位。嵌入过程开始时，首先伪随机地选择一个图像块bi，用它对第i个消息比特进行编码。令Bi=D{bi}为DCT变换后的图像块。
在通信开始前，发送者和接收者必须对嵌入过程中使用的两个DCT系数的位置达成一致，让我们用(u1,v1)和(u2,v2)来表示这两个索引。这两个系数应该相应于余弦变换的中频，确保信息保存在信号的重要部位(从而使嵌入信息不容易因JPEG压缩而完全丢失

SCM
通过设置不同的参数利用Matlab软件仿真了不同场景下的系统性能
(This document suggests a user’s guide to a MATLAB application which simulates a Spatial Channel Model (SCM) based on reference [1] with some minor adjustments. It focuses on how to use the Graphical User Interfaces (GUIs) and the functions of the application and avoids going into specifics about the nature of the parameters as this is done analytically in the reference document)

Real-Coded-Genetic-Algorithm-for-Robust
Power system stabilizers (PSS) are now routinely used
in the industry to damp out power system oscillations. In this paper,
real-coded genetic algorithm (RCGA) optimization technique is
applied to design robust power system stabilizer for both singlemachine
infinite-bus (SMIB) and multi-machine power system. The
design problem of the proposed controller is formulated as an
optimization problem and RCGA is employed to search for optimal
controller parameters. By minimizing the time-domain based
objective function, in which the deviation in the oscillatory rotor
speed of the generator is involved stability performance of the
system is improved. The non-linear simulation results are presented
under wide range of operating conditions disturbances at different
locations as well as for various fault clearing sequences to show the
effectiveness and robustness of the proposed controller and their
ability to provide efficient damping of low frequency oscillations.
