In this article, vibration analysis of an Euler-Bernoulli beam resting on a Pasternak-type foundation is studied. The governing equation is solved by using a spectral finite element model (SFEM). The solution involves calculating wave and time responses of the beam. The Fast Fourier Transform function is used for temporal discretization of the governing partial differential equation into a se...

Randall and Sundrum [1] first proposed the bulk-brane model to explain the higher dimensional theory. According to them, we live in a four dimensional world (called 3-brane, a domain wall) which is embedded in a 5-dimensional space-time (called bulk). The extra fifth dimension may be finite or infinite in size. All matter fields are confined in the brane while gravity can only propagate in the ...

transfer learning allows the knowledge transference from the source (training dataset) to target (test dataset) domain. feature selection for transfer learning (f-mmd) is a simple and effective transfer learning method, which tackles the domain shift problem. f-mmd has good performance on small-sized datasets, but it suffers from two major issues: i) computational efficiency and predictive perf...

reflection seismic data consist of primary reflections, coherent and incoherent noises. one of the objectives of seismic data processing is to enhance the quality of the real signals by attenuating different kinds of noises. multiples constitute one of the most troublesome forms of coherent noises in exploration seismology. multiple reflections often destructively interfere with the desired pri...

In this paper, the singular boundary method (SBM) in conjunction with exponential window (EWM) is firstly extended to simulate transient dynamic response of two-dimensional saturated soil. The frequency-domain (Fourier space) governing equations Biot theory solved by SBM a linear combination fundamental solutions. order avoid perplexing fictitious solution (MFS), places source point on physical...

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 dynamic response of a transversely isotropic, linearly elastic layer bonded to the surface of a half-space of a different transversely isotropic material under arbitrary shape surface loads is considered. with the help of displacements and stresses green’s functions, an analytical formulation is presented for the determination of the displacements and stresses at any point in both surface l...

This paper deals with the extraction of wave features in elastic media. An inverse approach is proposed for identification dispersion characteristics (e.g. k-space) one- and two-dimensional structures (1D, 2D). The method similar to ESPRIT algorithm Prony series can be considered as an extension latter, specifically when applied 1D problems. By using a convolution framework, extended 2D case wh...

the main aim is to study the two dimensional axisymmetric problem of thick circular plate in modified couple stress theory with heat and mass diffusive sources. the thermoelastic theories with mass diffusion developed by sherief et al. [1] and kumar and kansal [2] have been used to investigate the problem. laplace and hankel transforms technique is applied to obtain the solutions of the governi...
