Network anomaly detection is a critical aspect of network management for instance for QoS, security, etc. The continuous arising of new anomalies and attacks create a continuous challenge to cope with events that put the network integrity at risk. Most network anomaly detection systems proposed so far employ a supervised strategy to accomplish the task, using either signature-based detection me...

Abstract: The specific rate of breakage is one of the most important factors in evaluation of grinding process especially in ball mill. In this article the effect of ball size and feed size on selection function were investigated using batch grinding circuit on two-iron ore anomaly (B, C) from sangan mine in north of Iran. Eight different monosize fractions were prepared between 2000 and 50...

The purpose of this study is to determine geochemical anomalies on lithogeochemical data from Ardestan area, Central Iran, using concentration-number (C-N) fractal modeling and staged factor analysis. Staged factor analysis is used to the recognition of genetic correlation and elimination of non-indicator elements in three steps. Factor scores of elements were calculated and geochemical data cl...

These vessel mtures are however generally buried within noise ’ith variance of the order of the vessel signal it,ll. We present a scale-matched feature detector esigned to extract nominally 1-dimensional ridges ̄ ore an ...

Recent analyses of the cosmic microwave background (CMB) maps from the WMAP satellite have uncovered evidence for a hemispherical power anomaly, i.e. a dipole modulation of the CMB power spectrum at large angular scales with an amplitude of ±14 percent. Erickcek et al have put forward an inflationary model to explain this anomaly. Their scenario is a variation on the curvaton scenario in which ...
