one of the important elements of islamic architecture is mirror and mirror work. the art of mirror work is a persian traditional art which is usually used in the interior decoration of historical buildings, particular religious buildings. mirror work is considered as a kind of mural painting, but it is different from other types of mural paintings all around the world regarding its conceptual, ...

Formulas described in this paper were designed for the use in least-squares tomographic inversion methods with improved flexibility of parametrizing the density-velocity model. The gravity effect of the considered volume fl is the sum of gravity effects of 2-3 or 2 1/2-D bodies of polygonal cross-sections which form the disjunctive decomposition of fi. For this geometrical arrangement analytica...

In this paper, our aim is to develop a logical representation for form documents. We propose a hierarchical structure to represent the logical layout of a form by using lines. The approach is top-down and no domain knowledge such as the preprinted data or filled-in data is used. Logically same but physically different forms are associated to the same hierarchical tree. This representation can h...

Abstract — In this paper we derive the matrix of transformation of the Jacobi polynomial basis form into the Bernstein polynomial basis of the same degree n and vice versa. This enables us to combine the superior least-squares performance of the Jacobi polynomials with the geometrical insight of the Bernstein form. Application to the inversion of the Bézier curves is given. 2000 Mathematics Sub...

Particles adsorbed on the surface of a droplet form three-dimensional packings when the droplet evaporates. We study the final packings when the liquid droplet is attached to a solid substrate. In contrast to a droplet evaporating away from a substrate, here the final packings are highly dependent on both the number of particles and the contact angle between the droplet and the surface. Simple ...
