The Number of Traveling Wave Families in a Running Water with Coriolis Force

چکیده
In this paper, we study the number of traveling wave families near a shear flow under influence Coriolis force, where speeds lie outside range u. Under $$\beta $$ -plane approximation, if u has critical point at which attains its minimal (resp. maximal) value, then unique transitional value exists in positive negative) half-line such that changes suddenly from finite to infinite when passes through it. On other hand, no points, is always for values. This true general flows mildly technical assumptions, and large class including cosine jet $$u(y) = {1+\cos (\pi y)\over 2}$$ (i.e. sinus profile) analytic monotone unconditionally. The sudden change indicates long time dynamics around much richer than non-rotating case, exist.

Shallow water equations with a complete Coriolis force and topography
This paper derives a set of two dimensional equations describing a thin inviscid fluid layer flowing over topography in a frame rotating about an arbitrary axis. These equations retain various terms involving the locally horizontal components of the angular velocity vector that are discarded in the usual shallow water equations. The obliquely rotating shallow water equations are derived both by...

15 صفحه اولWave systems with an infinite number of localized traveling waves.
In many wave systems, propagation of steadily traveling solitons or kinks is prohibited because of resonances with linear excitations. We show that wave systems with resonances may admit an infinite number of traveling solitons or kinks if the closest to the real axis singularities of a limiting asymptotic solution in the complex upper half plane are of the form z±=±α+iβ, α≠0. This quite genera...

با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
15 صفحه اولComparison of Ground Reaction Force Components during Running with Running Shoes and Control Shoes in Individuals with Genu Varum
Introduction: Running poses an essential role in maintaining cardiovascular health. However, it has been demonstrated that 2.5 to 38 injuries per 1,000 hours of running can occur. The purpose of this study was to investigate ground reaction forces components during running with running shoes compared to control shoes in individuals with genu varum. Methods: This study was laboratory and semi-e...
