Deformable surface models are often represented as triangular meshes in image segmentation applications. For a fast and easily regularized deformation onto the target object boundary, the vertices of the mesh are commonly moved along line segments (typically surface normals). However, in case of high mesh curvature, these lines may not intersect with the target boundary at all. Consequently, ce...

BACKGROUND Tooth extraction is associated with dimensional changes in the alveolar ridge. The aim was to examine the effect of single versus contiguous teeth extractions on the alveolar ridge remodeling. MATERIAL AND METHODS Five female beagle dogs were randomly divided into three groups on the basis of location (anterior or posterior) and number of teeth extracted - exctraction socket classi...

The formation of the cold ridge, a seasonal mid-shelf upwelling feature on Agulhas Bank, is investigated from combination satellite-tracked surface drifters, in situ current and temperature data, as well satellite sea (SST) chlorophyll-a (Chl-a). observational data showed coastal along Tsitsikamma coast to be induced by easterly wind austral summer, with coexistent westward flowing current. Und...

bilateral finger and palm prints of 500 males and 500 females of the caucasian origin in south iran have been collected and analyzed for both qualitative and quantitative dermatoglyhic features. results show that most of the qualitative features on bilateral and bisexual differences are not significant. however, quantitative features frequently showed significant differences both bilaterally an...

In this paper, we study a new problem of finding a convex drawing of graphs with a non-convex boundary. It is proved that every triconnected plane graph whose boundary is fixed with a star-shaped polygon admits a drawing in which every inner facial cycle is drawn as a convex polygon. Such a drawing, called an inner-convex drawing, can be obtained in linear time.

In this paper we consider the problem of blood vessel segmentation in retinal images. After enhancing the retinal image we use green channel of images for segmentation as it provides better discrimination between vessels and background. We consider the negative of retinal green channel image as a topographical surface and extract ridge points on this surface. The points with this property are l...

PURPOSE This study assessed the impact of mandibular bone height on masticatory performance following treatment with a mandibular conventional denture (CD) or implant-retained overdenture (IOD). MATERIALS AND METHODS Evaluation of masticatory performance in 63 participants was made with original CDs and 6 months after treatment completion with new dentures; 25 patients received a mandibular C...
