We produce painterly images of 3D models by covering them in a particle system of brush strokes. Strokes move along with the original object, producing smooth animations. Strokes are rendered in multiple layers; higher layers show detail and appear in areas of high specular value. Strokes orient and curve themselves along edges and towards centers of light. We have avoided the use of the painte...

Intestinal mucosa of rats was prepared by squeezing the frozen and thawed intestine. The method was much easier compared to the conventional method in which intestine was cut longitudinally or everted and mucosa was scraped. Jejunal mucosal weight prepared by the two methods was not different, but ileal mucosal weight prepared by squeezing was significantly heavier than that by scraped. No sign...

We present a novel algorithm for stylizing photographs into portrait paintings comprised of curved brush strokes. Rather than drawing upon a prescribed set of heuristics to place strokes, our system learns a flexible model of artistic style by analyzing training data from a human artist. Given a training pair — a source image and painting of that image — a non-parametric model of style is learn...

Realistic representation of various effects which are appeared in the real world paintings can be used for several applications like as animation or education. To generate Oriental paintings, numerous studies have focused on model-based approaches. In this paper, a new modelbased approach for Oriental paintings is described. To represent the diffusion effects, we propose local equilibrium model...

In this paper, mechanical buckling analysis of composite annular sector plates with bean shape cut out is studied. Composite material sector plate made of Glass-Epoxy and Graphite-Epoxy with eight layers with same thickness but different fiber angles for each layer. Mechanical loading to form of uniform pressure loading in radial, environmental and biaxial directions is assumed. The method used...

2014 Our recent theory of the free energy and conformations of end-grafted polymer « brushes » is extended to polymers attached to curved surfaces. Several important systems, e.g., layers of polymeric surfactants or of strongly segregated diblock copolymers, can be well described as brushes. By expanding in powers of the curvature the free energy of a brush on a curved surface, the mean and Gau...

background: the purpose of this study was to describe the knowledge and attitude of pregnant women in qazvin province, central iran, relating to oral hygiene. methods: the study group comprised of 760 pregnant women living in qazvin, center of iran in 2004. the questions were formulated to evaluate information without the need for dental examination. the age groups between 17-41 years old were ...
