Stability and Bifurcation of the Magnetic Flux Bound States in Stacked Josephson Junctions

stability and attraction domains of traffic equilibria in day-to-day dynamical system formulation

در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...

Stability and Bifurcation of Rotor Motion in a Magnetic Bearing

The equations of motion of a two-degrees-of-freedom mass in a magnetic bearing are non-linear in displacement, with geometric coupling of the magnetic bearing coupling the horizontal and vertical components of rotor motion. The non-linear forced response is studied in two ways: (1) using imbalance force; (2) using non-imbalance harmonic force. In the forced response, only periodic motion is inv...

The Stability and Self-organization of 3d Bidisperse Cellular Fluids

The possibility of formation of cellular systems composed of two immiscible fluids, A and B, immersed in a continuous liquid medium C, has been examined. The system under study is formed as a result of the insertion of small bubbles or droplets of fluid A into a drained monodisperse foam/emulsion consisting of bubbles/droplets of fluid B separated by a thin film of liquid C. Interfacial tension...
