Calculation of the reflected waves against obstacles is a prominent step in designing coastal structures. In addition, a complex process occurs during wave collision with beaches or breakwaters. These processes cause wave characteristics to be (energy dissipation, reflected wave, etc.). The new wave characteristics are dependent on reflected wave height straightly which are not measureable. In ...

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

In this paper a multi-body system of barge type wind turbine under stochastic wave and wind has been modeled within MSC ADAMS. For wind loading, the stochastic turbulent wind data have been extracted using TurbSim software.Also, the AeroDyn module has been used for calculating lift and drag forces on the blades of turbine.. The hydrodynamic loads have been calculated using HydroDyn module withi...

the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...

Analytical analysis of a two-dimensional submerged body moving with a constant velocity in an inviscid incompressible fluid under gravity near a free surface is studied in this paper. This notion is one of the fundamental concepts in applied hydrodynamics. Experimental observations of water waves in large scale or laboratory observation in open channels is indicative of complex phenomenons taki...
