This the mathematical computational method of step-vary Gill method.

基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

OFDM调制模型，采用16QAM方式，并介绍了一种基于这种调制方式下的OFDM载波同步方法。每一步都有英文解释。(OFDM modulation model, using 16QAM mode and introduced an approach based on this modulation method under the OFDM carrier synchronization. English to explain every step.)

基于Logstic回归分析，建立人口预测模型，对人口数量进行预测(Based Logstic regression analysis, population forecasting model to predict population)
