So that make application to pair wise multiple comparison procedure duncan and least significant difference (LSD) to explain the most effectiveness (LSD). The most effective factors in four main roads in sulamania city, which choose randomly. The noise measurements at (9) periodic times: Morning peak traffic (6.30 - 9.30) hours. Divided in to four periodic times, afternoon peak traffic (1.30 - 3.30) hours. Divided in to three periodic times and Evening peak traffic (6- 8) hours divided in to two periodic times

For the reliability of system, it is wanted to improve highly appropriate wind speed forecasting methods. The wavelet transform is a powerful mathematical technique that converts an analyzed signal into a time-frequency representation. This technique has proven useful in a nonstationary time series forecasting. The aims of this study are to propose a wavelet function by derivation of a quotient from two different Lucas polynomials, as well as a comparison between an artificial neural network (ANN) and wavelet-artificial neural network (WNN). We used the proposed wavelet, Mexican hat, Morlet, Gaussian, Haar, Daubechies, and Coiflet to transform the wind speed data using the continuous wavelet transform (CWT). MATLAB software was used to implement the CWT and ANN. The proposed models were applied in the meteorological field to forec...

The problems can be summarized as that the oil exports don’t constitute a large share of N.I. only, but it also makes up most of the saving of the oil states. The oil prices affect their market through the interaction of supply and demand forces of oil. The research hypothesis states that the movement of oil prices caused shocks, crises, and economic problems. These shocks happen due to changes in oil prices need to make a prediction within the framework of economic planning in a short run period in order to avoid shocks through using computer techniques by time series models.
