We propose three diierent physical models based on linear elasticity theory and nite-elements modeling that are well-suited for surgery simulation. The rst model combines pre-computed deformations to deform in real-time large size meshes but does not allow any topo-logical changes to the mesh. The second model is similar to the spring-mass models where volumetric deformations and cutting operat...
Scanning the deformation behavior of real objects is a useful technique to acquire physically realistic behavior. It has been shown previously how to acquire physically realistic object behavior for small deformation and how to render the behavior at interactive rates. This paper introduces a novel method to extend previous work to handle large scale deformation. We model large scale deformatio...
We describe the first-order variations of the angles of Euclidean, spherical or hyperbolic polygons under infinitesimal deformations such that the lengths of the edges do not change. Using this description, we introduce a quadratic invariant on the space of first-order deformations of a polygon. For convex polygons, this quadratic invariant has a positivity property, leading to a new proof of t...
from historical facts to geo-political realities: relation between turkey and armenia ( 1915 – 2010)
armenias geopolitics and its historical experience have had a determining impact on the character of its foreign policy .present-day armenia is a small, landlocked country with _11,620 square miles area armenias landlocked nature makes it dependent on the benevolence of its neighbors for access to the outside world a fact that gives it a sense of isolation and vulnerability. as it was indic...
This paper investigates the financial stability, measured by z-score technique in Islamic banking system of 20 countries from 2000 to 2010. We compare the stability of Islamic banks to the commercial banks, before and after the financial crisis. The empirical results from panel estimation show that: a) the large Islamic banks are more stable than the large commercial banks and furthermo...
