the existing theory for wave propagation through a soil layer are not compatible with the real soil layers because in the theory the layers are flat and the sub-layers are parallel, while in real the soil layers are not flat and they may not be parallel. thus, wave propagations through a corrugated interface are so important. in this paper, a two-dimensional sh-wave propagation through a corrug...

It has been previously shown that a radially periodic image having a symmetric radial period can be decomposed into a circular Fourier series of circular cosine functions with radial frequencies of f = 1/T , 2/T , . . . , and that its Fourier spectrum consists of a series of half-order derivative impulse rings with radii f = n/T (which are the Fourier transforms of the circular cosines in the s...

Based on three-dimensional theory of elasticity, static analysis of functionally graded carbon nanotube reinforced composite (FG-CNTRC) cylindrical panel subjected to mechanical uniformed load with simply supported boundary conditions is carried out. In the process, stress and displacement fields are expanded according to the Fourier series along the axial and circumferential coordinates. From ...

Nowadays, the risk of degradation of wetlands is one of the main environmental challenges in the world, so continuous and long-term monitoring of ecological changes in wetlands can play a key role in their protection and proper management. In the present study, the trend of monthly changes in some of the most important ecological indicators of the aquatic environment of Shadegan wetland includi...

“any science seeks generalities; the aim is to transcend knowledge of particular cases by discovering general regularities or laws” (chesterman, 2001, p. 1). these were the words of chesterman whose paper has served as a typical example of numerous papers carried out on ‘translation universals’ since the mid-nineties. blum-kulka (1986) is among translation studies scholars who proposed ‘explici...

Observing a reasonable deadline throughout the criminal investigation process, as one of the most fundamental defensive rights of the accused, emphasizes the importance of reasonable expediting in the process of proceedings in a high degree of accuracy, which considers necessary for the fair trial and the desired outcome of criminal proceedings. Delivering justice within a reasonable time is on...
