In this study, Mazandaran province's coasts have been classified by using Relative Tide Range,  and  hydrodynamic models. For this, investigations of waves hydrodynamics, measurement of bed morphology's profiles and sediment characteristics along surfzone, and analyzing of hydrographic maps at 7 stations in east (Neka, Larim and Babolsar), middle (Mahmudabad and Kohnesara) and west pa...

ساختارهای مزوسکوپیک شامل لایه های فرومغناطیس و ابررسانا مورد توجه زیادی قرار گرفته اند. این ساختارها همبستگی کوانتومی بین آثار همدوسی در فلز عادی یا فرومغناطیس و همدوسی ذاتی ابررسانایی را که توسط بازتاب آندریو تامین می شود، به نمایش می گذارند. در این پایان نامه رسانندگی تونلی یک پیوند ابررسانای نوع-p‎/ فلز عادی/ فرومغناطیس ‎( f/n/p-wave sc)‎ بر پایه گرافن را با استفاده از معادله دیراک-بوگولیوبو...

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 ...

Oscillating water column (OWC) is one of the wave energy converting devices available. In this article, a numerical model has been introduced to simulate wave interaction with OWC in one dimensional plane. Mild slope equations have been used in one dimension. The pressure and water elevation inside OWC have been calculated using an iterative method. Also an absorbing boundary is used at the beg...

Ultrasonic horn with transfer of acoustic wave into an aqueous solution results in unique properties. When, transfer of sound wave into a liquid results in liquid movement in the direction of wave propagation which gradually loses its energy due to the viscous friction. This wave motion induces a flow which is known as acoustic streaming or micro-streaming. In this article, a simple innovative ...
