the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Fully nonlinear dynamics of stochastic thin-film dewetting.
The spontaneous formation of droplets via dewetting of a thin fluid film from a solid substrate allows materials nanostructuring. Often, it is crucial to be able to control the evolution, and to produce patterns characterized by regularly spaced droplets. While thermal fluctuations are expected to play a role in the dewetting process, their relevance has remained poorly understood, particularly...
متن کاملVibration Attenuation of Nonlinear Hysteretic Structures with Fully Unknown Parameters
Natural hazards such as earthquakes have threatened the life of human beings during the history.As a consequence, the vibration mitigation of structures has caught great importance. Activecontrol of structures is one of the rapidly emerging areas in the concept of structural control. Thispaper presents a control method to deal with this subject when the dynamics of the structure ishysteretic an...
متن کاملEfficient fully nonlinear data assimilation for geophysical fluid dynamics
6 A potential problem with Ensemble Kalman Filter is the implicit Gaussian as7 sumption at analysis times. Here we explore the performance of a recently pro8 posed fully nonlinear particle filter on a high-dimensional but simplified ocean 9 model, in which the Gaussian assumption is not made. The model simulates 10 the evolution of the vorticity field in time, described by the barotropic vortic...
متن کاملParallel Simulation of Lifting Rotor Wakes in Forward Flight
A finite-volume implicit, unsteady, multiblock, multigrid, upwind solver, and structured multiblock grid generator for rotors are presented, and applied to lifting rotors in forward flight. These flows are particularly expensive to compute as the accurate capture of the detailed vortical wake requires fine meshes away from the blades and, hence, a parallel version of the code has been developed...
