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...

CVA Special Issue: Surface Detail in Computer Models

Traditionally in vision, the reflectance of light at a surface has been modelled with rather simple linear combination of Lambertian and specular models. Such models are applicable for manmade scenes and where the surfaces are either “matte” or shiny, and rather uniform. An office scene with a desk, chalk, pen, stapler may be modeled well with these simple models. But real world scenes have a f...

Special issue on constrained design of curves and surfaces

It is indeed an honor and a pleasure to act as guest editors for this special issue on Constrained Design of Curves and Surfaces (CDCS). We would like to thank the editors of JCAD for supporting our view that generating, analyzing and modifying shapes is a process usually driven by a variety of constraints, whose methodological, algorithmic and computational handling deserves to obtain autonomy...

Construction of a surface pencil with a common special surface curve

In this study, we introduce a new type of surface curves called $D$-type curve. This curve is defined by the property that the unit Darboux vector $vec{W}_{0} $ of a surface curve $vec{r}(s)$ and unit surface normal $vec{n} $ along the curve $vec{r}(s)$ satisfy the condition $leftlangle vec{n} ,vec{W}_{0} rightrangle =text{constant}$. We point out that a $D$-type curve is a geodesic curve or an...
