In this article we consider the stochastic restricted ridge estimation in semipara-metric linear models when the covariates are measured with additive errors. The development of penalized corrected likelihood method in such model is the basis for derivation of ridge estimates. The asymptotic normality of the resulting estimates are established. Also, necessary and sufficient condition...

background and aims. autogenous onlay bone grafting is a common procedure for alveolar ridge augmentation. it has been suggested that the amount of healed bone after this technique would be significantly less than the initial quantity. the aim of this study was to determine the relationship between the various parameters influencing the outcome of ridge augmentation procedures. materials and me...

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...

The first description of the ganglion cyst is credited to Hippocrates, who described these lesions as "...flabby ganglionic tumors, containing only mucoid flesh..." Interestingly, this original description was quite accurate, and little more has been discovered about these soft tissue masses in recent medical times. Ganglion cysts have been reported extensively in the medical literature. Contro...

Background Dermatoglyphics could assist in the diagnosis of congenital abnormalities. The aim of this study was to identify the dermatoglyphic patterns (finger print pattern type, total ridge count of each finger, a-b ridge count, and articulotrochanteric distance [ATD angles]) in the parents of cystic fibrosis children. Materials and Methods We recruited 75 parents of children with cystic fibr...

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...

The proposed ridge features are composed of four elements: ridge count, ridge length, ridge curvature direction, and ridge type. For extracting ridge features, we also define the ridge-based coordinate system in a skeletonized image With the proposed ridge features and conventional minutiae features(minutiae type, orientation, and position), we propose a novel matching scheme using a breadth-fi...
