Full waveform inversion (FWI) is beginning to be used characterize weak seismic events at different scales, an example of which microseismic event (MSE) characterization. However, FWI with unknown sources a severely underdetermined optimization problem, and hence requires strong prior information about the and/or velocity model. The frequency-domain wavefield reconstruction method (WRI) has sho...

It has been analyzed that the word order of English comparative inversion is analogous to that of other subject-auxiliary inversions in that only a finite auxiliary verb can be followed by the subject. However, English comparative inversion should be distinguished from other inversions because the subject can be located between a cluster of auxiliary verbs and the non-auxiliary verb phrase in E...

The face inversion effect has been used as a basis for claims about the specialization of face-related perceptual and neural processes. One of these claims is that the fusiform face area (FFA) is the site of face-specific feature-based and/or configural/holistic processes that are responsible for producing the face inversion effect. However, the studies on which these claims were based almost e...

the source parameters and focal depth of the destructive mw 6.5, 31 march. 2006 iran- silakhor earthquake, the two largest foreshocks and a major aftershock are determined using broadband data from a seismic network in iran based on a time-domain linear moment tensor inversion. the earthquakes occurred in the zagros suture zone in western iran. waveform inversion of the selected events estimate...

There is growing interest in developing a three-dimensional (3-D) inversion and imaging technique from a single borehole. This problem can be solved by using tensor (multi-component) induction welllogging – TIWL. This method was originally introduced to resolve formation anisotropy. However, it was demonstrated in several publications that the TIWL instrument has sensitivity to 3-D conductivity...

introduction air pollution as one of the most important technological risks of contemporary era is mainly resulted from the emergence of large cities and fast growing industries. one of the main objectives of climatic and environmental studies is to survey atmospheric pollutions. tabriz is one of the metropolises where air pollution is a problem in it. of course, what is essential regarding the...
