Accurate boundary determination and segmentation of an object interest in image is a difficult task. In this paper, we propose new model which improves the old selective Rada et al. [23] by combining two penalization fitting terms. To better deal with oscillatory boundaries, H^1 weighted length term L^2 Lebesgue measure have been employed as terms, whereas terms consist region-based area term. ...

In this paper we show that there are infinitely many pairs of integer isosceles triangles and integer parallelograms with a common (integral) area and common perimeter. We also show that there are infinitely many Heron triangles and integer rhombuses with common area and common perimeter. As a corollary, we show there does not exist any Heron triangle and integer square which have a common area...

Introduction With the advancement in imaging technology, 3D dental computed tomography plays a very significant role in orthodontic treatment and diagnosis. Aim To evaluate dental crowding in relation to the mesiodistal crown widths and arch dimensions and also to determine the differences of dental crowding among males and females, in Southern Indian population.
