Abstract To ensure the enhanced artificial neural network applications for spatial localization stochastic EM radiation sources, we present a system with results. We have given the stochastic sources near field representation with antenna arrays and dipole elements. Besides, the correlation matric calculation architecture is presented. It will help to develop neural models for the 1D and 2D DoA estimation. In addition,... Read More

Abstract We have used the mean variance optimization system in the paper to represent the portfolio risk optimization. We have measured the optimal proportional assets in the portfolio and ensure the return of assets with no less than the given target value. With its use we have fixed the benefits of the given target value. We have used the MATLAB solver... Read More


An Interface Architecture of Source-Synchronous Differential Point-To-Point Parallel Link

Abstract To transmit parallel data is normally we use clock across printed circuit board so that the skew problem is addressed. The issue is that the phase relation of the data and clock can be a failure due to different travel times through the link. We fixed the issue with an interface architecture of source-synchronous differential point-to-point parallel link. We used... Read More
