in coastal areas, hydrodynamic factors make changes in shorelines geomorphology. this can affect coastal facilities and cause hazards to human societies in the areas. this study has investigated the influence of wave and tide properties on khamir port, hormoz strait in coast of persian gulf. the purpose of the study is to make a mathematical regional and local modeling of water level fluctuatio...

Floating breakwaters are widely used due to their various advantages over stationary breakwaters. Lots of researches have been done on hydrodynamics and the type of bracing of these kinds of structures in recent years. In this study, numerical modeling of stresses caused by collision waves has been investigated. For this purpose, samples of floating breakwaters have been modeled in ANSYS softwa...

Fishermen frequently suffer accidents and may even drown when they are swept into the sea by coastal freak waves near shore of northeastern Taiwan. To accurately predict deformation free surfaces violently strike structures, smoothed particle hydrodynamics (SPH) model with a nonlinear mesh-free numerical approach was adopted in this study. Eight cases based on an actual wave accident were simul...

among different discretization approaches, finite difference method (fdm) is widely used for acoustic and elastic full-wave form modeling. an inevitable deficit of the technique, however, is its sever requirement to computational resources. a promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...

In this paper, inference model is proposed so as to analyze nonlinearly loaded dipole antenna. In modeling process, linear and nonlinear behavior of the problem is saved as simple and unchanged membership functions and the effect of incident wave on the induced voltage at different harmonies are then extracted easily. Consequently the model achieved is more efficient than previous studies using...

In this paper, on the basis of a new strain gradient elasticity theory, wave propagation in rectangular nanoplates by considering in-plane magnetic field is studied. This strain gradient theory has two gradient parameters and has the ability to compare with the nonlocal elasticity theory. From the best knowledge of author, it is the first time that this theory is used for investigating wave pro...

nowadays, the application of floating breakwaters in small or recreational harbors has found more popularity. these types of breakwaters are more flexible in terms of design, configuration and especially installation compared with fixed breakwaters. in the current study, the performance of floating breakwater (fbs) under regular waves was studied using the physical modeling method. for the mode...
