this paper attempts to investigate the capability of the numerical finite element method for the removal of the regional effects from the observed gravity data from the dehnow anticline. from a geological point of view, the dehnow area is a part of the fars sedimentary basin south-east iran. the khamy formation and bangestan group are the oldest geological structures in the area that have outcr...

abstract the study of natural disasters is one of the most important primary principles for the growth of developing cities and the development of infrastructures. to this end, evaluating geodynamic activities using morphological data is considered one of the most pivotal applied methods. in this study, it was tried to detect active faults in yazd province using desert studies and remote sensin...

For the past few years Artificial Neural Networks (ANN) have made a strong comeback to the scientific community. They are used in a variety of tasks where adaptive computing can enhance process performance. There has been a handful of papers suggesting the use of artificial neural networks in the petroleum industry . These 1-3 papers can be classified into two major categories. First category i...

Can the reflection response of the subsurface be obtained without the need to place an active source at the surface? Using numerical modeling results based on one-way wavefields, we show that the reflection response of a 3-D inhomogeneous lossless medium can be reconstructed from the crosscorrelation of its transmission response at the surface. Depending on the type of subsurface noise sources,...

A network of 23 analog seismic stations was established in Pakistan to monitor seismic activity. The instrumentation of seismic stations includes short period seismometers with natural period at 1 Hz. The seismic noise conditions of five seismic stations are studied to determine the detection capability in the frequency range from 1.0 Hz to 10.0 Hz regarding monitoring of local and regional sei...
