PURPOSE This study investigated the effect of amount of thickness reduction on color and translucency of dental monolithic zirconia ceramics. MATERIALS AND METHODS One-hundred sixty-five monolithic zirconia specimens (16.3 mm × 16.3 mm × 2.0 mm) were divided into 5 groups (Group I to V) according to the number of A2-coloring liquid applications. Each group was then divided into 11 subgroups b...

Background: The practice of surrogacy is one of the most controversial procedures in infertility treatment. Despite increasing of using this technology in Iran, there are few practical data about surrogacy.There isn't any study assessing experiences of commissioning mothers about surrogate mother selection. Aim: The purpose of this study was exploring of commissioning mothers' experiences in se...

Preliminary design of a complex system often involves exploring a broad design space. This may require repeated use of computationally expensive simulations. To ease the computational burden, surrogate models are built to provide rapid approximations of more expensive models. However, the surrogate models themselves are often expensive to build because they are based on repeated experiments wit...

Translucency of dental ceramics, esthetic posts and orthodontic brackets was reviewed. Translucency parameter (TP) and contrast ratio (CR) are generally used for translucency evaluation. For the evaluation of translucency, two criteria such as the translucency of human teeth (TP = 15-19, 1 mm thick) and the visual perceptibility threshold for the translucency difference (∆CR > 0.07 or ∆TP > 2) ...

This paper investigates the applicability of surrogate model optimization (SMO) using deep learning regression models to automatically embed knowledge about objective function into process. demonstrates two SMO methods for calculating simple neutronics parameters. Using these models, returns results comparable with those from early stages direct iterative optimization. However, this study, cost...

Added credits to the s∗ACM-ES algorithm. Section 1 Added references and clarified the motivation. Section 3 Added references. Abstract: The interest in accelerating black-box optimizers has resulted in several surrogate model-assisted version of the Covariance Matrix Adaptation Evolution Strategy, a state-of-the-art continuous black-box optimizer. The version called Surrogate CMA-ES uses Gaussi...
