Dynamics of a discrete-time plant-herbivore model

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...

Efficient simulation under a population genetics model of carcinogenesis

MOTIVATION Cancer is well known to be the end result of somatic mutations that disrupt normal cell division. The number of such mutations that have to be accumulated in a cell before cancer develops depends on the type of cancer. The waiting time T(m) until the appearance of m mutations in a cell is thus an important quantity in population genetics models of carcinogenesis. Such models are ofte...

Computational fluid dynamics simulation of a very dense liquid-solid flow using a Eulerian model

Segregation in a dense solid-liquid multiphase flow is complicated by its interactions between phases. In this paper, the segregation of dense solid-liquid flow was simulated using the Finite Volume Method. A Euler-Euler multiphase simulation was conducted for the dense solid-liquid flow. The flow in the viscous regime was evaluated using kinetic theory describing the flow of smooth, slightly i...
