Magnetic investigations can yield important information about geological structures. Singular Value Decomposition (SVD) is a very powerful tool for analysis of the geophysical data set chiefly potential fields. In this paper, a new technique for demonstration of near-subsurface features with short wavelength using magnetic eigenvectors and eigenima...

Fig.3a and b have been reconstructed using the two first eigenimages and remaining eigenimages, respectively. In Fig.3b, the effect of the regional magnetic field background ( Fig. 3a) has been eliminated and the residual anomalies have been detected with high ...

After the Stuxnet security event in Iran, the security issues on industrial Internet are very serious. Besides, there are many aws existing in the modern traffic modelling approaches to the industrial field network. Aiming at these problems, the traffic characteristic map-based intrusion detection model for industrial Internet was proposed. Firstly...
