BACKGROUND The present study aimed at evaluating the efficacy of a novel technique, the bone lamina technique, in horizontal ridge augmentation clinically & radiographically using a combination of allogenic cortical shell, particulate xenograft and resorbable collagen membrane. MATERIAL AND METHODS Localized horizontal ridge defects, in ten patients (6 male, 4 female), with bucco-palatal ridg...

Regeneration was studied in the Ambystoma annulatum by the amputation of the right forearm of twenty-four adults, over a twelve month period. Atthe termination of the experiment the limbs were reamputated 1-2 mm proximal to the original amputation site. The regenerated portions were staged, examined at the gross morphological level, and prepared for histological examination. Gross examination r...

Objective: This paper aims to introduce a modified kernel-type ridge estimator for partially linear models under randomly-right censored data. Such models include two main issues that need to be solved: multi-collinearity and censorship. To address these issues, we improved the kernel estimator based on synthetic data transformation and kNN imputation techniques. The key idea of this paper is t...

Ridge regression is often favored in the analysis of ill-conditioned systems. A canonical form identifies regions in the parameter space where Ordinary Least Squares (OLS) is problematic. The objectives are two-fold: To reexamine the view that ill-conditioning necessarily degrades essentials of OLS; and to reassess ranges of the ridge parameter k where ridge is efficient in mean squared error (...

Deformities of the dentoalveolar ridge are usually the result of developmental defects, periodontal disease, trauma, or surgical insult. Various techniques are available to correct ridge defects. In this case presentation, ridge augmentation was achieved utilizing an acellular dermal matrix allograft in lieu of an autograft. This report demonstrated an acceptable esthetic result with a signific...

The estimation of ridge parameter is an important problem in the ridge regression method, which is widely used to solve multicollinearity problem. A comprehensive study on 28 different available estimators and five proposed ridge estimators, KB1, KB2, KB3, KB4, and KB5, is provided. A simulation study was conducted and selected estimators were compared. Some of selected ridge estimators perform...

The aim of this study was to use photoelastic models to analyze the distribution of stress caused by the incidence of loads on a mandibular distal extension removable partial denture, both on the abutment teeth and on differently shaped residual ridges: distal ascending, descending-ascending, horizontal and distal descending. The best type of retainer and location of the rest on the last abutme...

This paper deals with ridge estimation of fuzzy nonparametric regression models using triangular fuzzy numbers. This estimation method is obtained by implementing ridge regression learning algorithm in the La- grangian dual space. The distance measure for fuzzy numbers that suggested by Diamond is used and the local linear smoothing technique with the cross- validation procedure for selecting t...

Ridges and ravines are the main components constituting a "ngerprint. Traditional automatic "ngerprint identi"cation systems (AFIS) are based on minutiaematching techniques. The minutiae for "ngerprint identi"cation are de"ned by ridge termination and ridge bifurcation. Most AFIS perform ridge line following process to automatically detect minutiae based on binary or skeleton "ngerprint image. ...
