چکیده
Long term power load has a big impact on the development of industry of power. The forecasting models of linear systems even a single forecasting model of the nonlinear systems can not forecast the long term power load greatly. In the study, the combined forecasting model of nonlinear systems including chaos and fractal was established to improve the accuracy of the forecast. First, the characteristics of chaos and fractal of data were analyzed. Second, the forecasting models based on chaos and fractal were used to forecast the data. Finally, using the combined forecasting model predicted the long term power load and compared the results of combined forecasting model with the results of the single forecasting model. The results show that the combined forecasting model based on chaos-fractal theory has better effect on the forecast of long term power load.

متن کاملImproving security of double random phase encoding with chaos theory using fractal images
This study presents a new method based on the combination of cryptography and information hiding methods. Firstly, the image is encoded by the Double Random Phase Encoding (DRPE) technique. The real and imaginary parts of the encoded image are subsequently embedded into an enlarged normalized host image. DRPE demands two random phase mask keys to decode the decrypted image at the destination. T...
