geophysical data are always affected by different sources of anomaly. these sources are classified in to three groups: first group is relatively deep sources commonly called as regional effects, second group is near surface sources or local effects and third group is high frequency noises. the only common way to separate the anomaly is separation with respect to the signal frequency. there are ...

The separation of concerns principle aims at decomposing a given design problem into concerns that are mapped to multiple independent software modules. The application of this principle eases the composition of the concerns and as such supports composability. Unfortunately, a clean separation (and composition of concerns) at the design level does not always imply the composability of the concer...

We present the preferential filtering method for gravity anomaly separation based on Green equivalent-layer concept and Wiener filter. Compared to the conventional upward continuation and the preferential continuation, the preferential filtering method has the advantage of no requirement of continuation height. The method was tested both on the synthetic gravity data of a model of multiple rect...

Recently, high-order statistics have received more and more interest in the field of hyperspectral anomaly detection. However, most of the existing high-order statistics based anomaly detection methods require stepwise iterations since they are the direct applications of blind source separation. Moreover, these methods usually produce multiple detection maps rather than a single anomaly distrib...

[1] The dominant Northern Hemisphere winter mode of variability is characterized by a same-signed sea level pressure anomaly at high latitudes with an opposite-signed anomaly stretching across mid-latitudes. The surface temperature pattern associated with this mode is a samesigned temperature anomaly across the major continents and an opposite-signed anomaly across the major oceans. We demonstr...

From the deep-inelastic momentum sum rule and the trace anomaly of the energy-momentum tensor, I derive a separation of the nucleon mass into the contributions of the quark and gluon kinetic and potential energies, the quark masses, and the trace anomaly. Typeset using REVTEX This work is supported in part by funds provided by the U.S. Department of Energy (D.O.E.) under cooperative agreement #...

Nowadays the use of hyperspectral imagery specifically automatic target detection algorithms for these images is a relatively exciting area of research. An important challenge of hyperspectral target detection is to detect small targets without any prior knowledge, particularly when the interested targets are insignificant with low probabilities of occurrence. The specific characteristic of ano...

Persistent double dorsal aorta is a rare congenital anomaly of the descending aorta. It is an anomaly with two variants. The first type is characterized by complete separation of two dorsal aortae. The second type is a double-lumen descending aorta with a central dividing septum from the level just below the ductal ligament to the aortic bifurcation. We present a completely separated double dor...
