The original antenna covered 3.4 to 13.5 GHz. The best simulation results of the proposed 2×1 MIMO antenna received for 2×1 inverted with high ultra-wideband (UWB) with bandwidth up to 40 GHz, the received maximum gain was up to 6.51 dB, with an average gain of more than the original single antenna at about +1.27 dB. The best of eight 2×2 MIMO antennas configurations that give good results were shown.

On the other hand, autoregression, which is based on regression equations, is a sequential model that uses time to predict the next step data from the previous step. Given the importance of accurate modelling and reliable predictions. in this paper we have analyzed the most popular methods used for data prediction. Nonlinear autoregressive methods were introduced, and then the machine deep learning approach was used to apply prediction based on a selected input data set. The mean square error was calculated for various artificial neural networks architecture to reach the optimal architecture, which minimized the error. Different artificial neural network (ANN) architectures were trained, tested, and validated using va...

The proposed method will be implemented and tested and the calculated parameters will be compared with the LSB method parameters. It will be shown that the proposed method provides a high-security level by using two keys to extract the secret message from the holding image, making it very difficult to hack.

So it was needed to separate red, blue and green components in order to get the gray equivalent of the color image. The gray image then will be processed using one or more image processing techniques, after that the processed color image will be converted back to enhanced color image. Converting color image to gray and converting the processed gray image back to color image were the tasks that needed a lot of calculation and so a lot of processing time. Decreasing this time to the minimum is a focal task in order to achieve an optimized processing. HSI model of conversion was studied and a new R'G'I model also was studied and the experimental results shows that using R'G'I model speed up the conversion and thus minimize the time at least 8 times, thus R'G'I model can replace...

Comparing with the Hilbert Transform the proposed method can extract envelopes of different carriers transmitted in the same channel.
