We describe spectra of associative (not necessarily unital and not countable-dimensional) locally matrix algebras. determine all possible algebras give a new proof Dixmier–Baranov Theorem. As an application our description spectra, we embeddings

coastal fars gravimetry project in fars province was carried out to find the buried salt domes and to determine characteristics of faults in this area. the lavarestan structure was covered by 4203 gravimetry stations in a regular grid of 1000*250 m. depth structural model of this anticline made in previous studies was based on geological evidences and structural geology measurements. in order t...

In this paper, modular neural network (MNN) inversion has been applied for the parameters approximation of the gravity anomaly causative target. The trained neural network is used for estimating the amplitude coefficient and depths to the top and bottom of a finite vertical cylinder source. The results of the applied neural network method are compared with the results of the least-squares stand...

We inverse the surface gravity data to recover subsurface 3D density distribution with two strategy. In the first strategy, we assumed wide density model bound for inverting gravity data and In the second strategy, the inversion procedure have been carried out by limited bound density. Wediscretize the earth model into rectangular cells of constant andunidentified density. The number of cells i...

the gravimetric method is one of the most effective ways for the detection of subsurface structures such as tunnels, faulting, mineral deposits with the required density difference, especially in areas with rough topography and tectonized formations. it is possible to provide a more suitable model for better interpretation of the gravity anomaly. inverse modeling of gravity data is the most eff...
