One of the efficient techniques to improve the behavior of the paved road under traffic loads is implementing the geosynthetic material in the sub-base or the soil under the road. In the past years, many researches have been done about this topic, but the study on the effect of soil/load conditions on the performance of the rehabilitated paved road by geogrid in order to investigate the effecti...

The implementation of high-order (spectral) approximations associated with FEM is an approach to overcome the difficulties encountered in the numerical analysis of complex problems. This paper proposes the use of the spectral finite element method, originally developed for computational fluid dynamics problems, to achieve improved solutions for these types of problems. Here, the interpolation n...

Large strains, anisotropy of mechanical properties of materials and Coulomb friction in contact regions are some properties in the analysis of deep drawing process. In this research, the effects of different parameters such as anisotropy coefficient, work hardening exponent and friction coefficient on deep drawing process of drawing quality steel are studied. For this purpose, the finite elemen...

The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...

Finite element method (FEM) for both linear and nonlinear cases is widely used solving time-dependent problems related to the geometrical configuration of electrical HTS devices AC losses. This paper presents our FEM models in development cables. Transient 3D have been developed optimization coaxial triaxial 2G In these models, only magnetic materials are considered. The transient 2D model was ...

The tra-2 gene of the nematode Caenorhabditis elegans encodes a predicted membrane protein, TRA-2A, that promotes XX hermaphrodite development. Genetic analysis suggests that tra-2 is a negative regulator of three genes that are required for male development: fem-1, fem-2, and fem-3. We report that the carboxy-terminal region of TRA-2A interacts specifically with FEM-3 in the yeast two-hybrid s...

Detailed Finite Element Method (FEM) based simulations for 2G HTS tapes return high quality results, but the computation takes a long time due to non-linearity of superconducting properties and they needed mesh density. This work describes method prediction quench behavior in tape on series 2D FEM model short length many different conditions. The random forest is trained by set results from sho...

We simulate electromagnetic (EM) measurements obtained by using one transmitter and one receiver antenna in a borehole environment. The measurements are used to assess electrical properties of rock formations. We have started from a problem where logging instruments as well as rock formation properties are assumed to exhibit axial symmetry around the axis of a vertical borehole. The initial com...
