near-surface variations can be very complex and may distort amplitudes and arrival times of the reflections events from target reflectors. near-surface complexities include topographic variations, near-surface irregularities, variations in soil conditions and the weathered layer. these perturbations generally have a significant impact on seismic recordings. although there is a general agreement...

displacement coefficient method (dcm) stipulated in the asce 41-06 standard is becoming the preferred method for seismic rehabilitation of buildings in many high-seismic-hazard countries. applications of the method for non-building constructions such as bridges are beyond the scope of this standard. thus its application to this kind of structure should be approached with care. target displaceme...

magnetotelluric (mt) method is an electromagnetic method which provides information about subsurface conductivity structures using earth's natural electromagnetic fields. static shift is one of disorders arising from shallow conductors; therefore static shift must be corrected as one of mt data processing steps. in the absence of sufficient information about the near surface distortions, w...

the purpose of this study is to correct the static shift of magnetotelluric (mt) data in one of the oil fields located in southwest of iran using time domain electromagnetic (tem or tdem) data. acquisition of the mt data has been made in the same area as the tem data was acquired at the frequency range of 0.0005-320 hertz. . a major problem in the mt method that occurs due to distribution of su...

The relativistic correction to the QCD static interquark potential at O(1/m) is investigated nonperturbatively for the first time by using lattice Monte Carlo QCD simulations. The correction is found to be comparable with the Coulombic term of the static potential when applied to charmonium, and amounts to one-fourth of the Coulombic term for bottomonium.

common programming and security flaws using static analysis of the C source code. These flaws may be serious errors or simple ones caused by programmer's carelessness and most of them may not be detected by the compilers. Manual reviewing of code for errors may take a lot of time especially if the code is big and it will also be very expensive, also simple flaws maybe overlooked .In this paper ...

The long range properties of four-dimensional compact U(1) lattice gauge theory with the Wilson action in the confinement phase is studied by using the multilevel algorithm. The static potential, force and flux-tube profile between two static charges are successfully measured from the correlation function involving the Polyakov loop. The universality of the coefficient of the 1/r correction to ...
