The present research investigates the implementations of different computational geometry technologies in isogeometric analysis framework for computational fracture mechanics. NURBS and T-splines are two different computational geometry technologies which are studied in this work. Among the features of B-spline basis functions, the possibility of enhancing a B-spline basis with discontinuities ...
in our present research, we focus on the modeling of airflow related to natural disasters, such assand accumulation, with urban form studies. the objective is to find which urban form can promote sand passing andreduce as much as possible stagnation of sand in the building area (streets, alleys, etc.). the urban form design will bediscussed through the simulation of airflow by using computation...
given a set of points in the plane and a constant ,-center problem is to find two closed disks which each covers the whole , the diameter of the bigger one is minimized, and the distance of the two centers is at least . constrained -center problem is the -center problem in which the centers are forced to lie on a given line . in this paper, we first introduce -center problem and its constrain...
مسیله پوشش برای شبکه های حسگر از دسته مسایل الگوریتمی مطرح شده برای این شبکه ها می باشد. در شبکه های حسگر بی سیم هر نود شبکه می تواند به ارزیابی منطقه تحت پوشش خود پرداخته و نتیجه حاصل از ارزیابی خود را برای حسگرهای همسایه اش بفرستد. به دلیل کاربردهای مختلفی که برای شبکه های حسگر بی سیم وجود دارد مطالعه مسایل مربوط به این شبکه ها مورد توجه پژوهشگران قرار گرفته است. مطالعه پوشش ایجاد شده توسط شب...
