the study of wave and its propagation on the water surface is among significant phenomena in designing quay, marine and water structures. therefore, in order to design structures which are exposed to direct wave forces, it is necessary to study and simulate water surface height and the wave forces on the structures body in different boundary conditions. in this study, the propagation of static ...

Abstract Wind induced wave is of great importance due to its high energy. In this study wave climate in the Gulf of Oman close to the Koohmobarak area is investigated. Wave climate study is necessary for determination of long-term analysis of wave statistics as well as climate change effects in the study area. First, wave climate is study using both measured and simulated wave data close to th...

starting from two-dimensional (2d) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. two different dynamic infinite elements taking into account single and two-wave types are presented in transformed space. by coupling the infinite elements with standard finite elements, an ordinary finite element procedure is used for...

As the computation power developing, the simulation of the explosion blast wave becomes more accurate and much more codes and softwares designed for this purpose. Besides the numerical methods, there are some other effectives like: turbulence model, equation of state and the explosion models which affect the accuracy of the blast wave simulation results. This paper reviewed the numerical method...

In this study, a mathematical model is developed based on algebraic equations which is capable of generating artificially normal events of electrocardiogram (ECG) signals such as P-wave, QRS complex, and T-wave. This model can also be implemented for the simulation of abnormal phenomena of electrocardiographic signals such as ST-segment episodes (i.e. depression, elevation, and sloped ascending...

five-zone simulating moving bed (smb) system, designed for ternary separation, is a modified form of standard four-zone smb which is only effective in binary separation. it was reported in literature that the five-zone smb separates the extract-ii stream with a lower purity value than that of raffinate and extract-i streams. to address this issue, five zone smb was designed, using safety margin...
