color match between fiber-reinforced composite (frc) restorations and teeth is an imperative factor in esthetic dentistry. the purpose of this study is to evaluate the influence of veneering composites and fibers on the color change of frc restorations.glass and polyethylene fibers were used to reinforce a direct microhybrid composite (z250, 3m espe) and a microfilled composite (gradia indirect...

Intelligent computer-vision system for automated inspection of food safety and quality (SAIF) developed on the basis of compact CCD camera with IEEE-1396 interface and configurable software (IMAQ TM 6.1, Lab VIEW 7.0) is presented. It offers an extensive set of optimized functions for advanced image acquisition, segmentation, feature extraction, data analysis, spatial measurement and calibratio...

Structural color based on Fabry–Perot (F-P) cavity enables a wide gamut with high resolution at submicroscopic scale by varying its geometrical parameters. The ability to design such parameters that can accurately display the desired is therefore crucial manufacturing of F-P cavities for practical applications. This work reports first inverse structure using deep learning through bidirectional ...

objective: selection of an appropriate shade of composite is critical in achieving an esthetic restoration. different systems are used to assess and describe color parameters. this study aimed to assess the effect of color and thickness of filtek supreme (fs) and premise (p) composite resins on correction of tooth discoloration.   methods: in this in vitro experimental study, 10 anterior teeth ...

For dry toner electrophotographic color printers, we present a numerical simulation model describing the color printer response based on a physical characterization of the different electrophotographic process steps. The proposed model introduces a Cross Transfer Efficiency designed to predict the color transmittance spectra of multi-color prints by taking into account the transfer influence of...

The boiler drum level control unit is one of the main parameter in the thermal power station. Currently the boiler drum parameters are monitored only by using MATLAB software. There is no automatic control available. In the proposed system the boiler drum parameters such as temperature level, pressure level, water level and Droplet identifier are measured and controlled by using embedded proces...

OBJECTIVES The aim of this study was to evaluate the inter-observer reliability of dental shade-matching device using an in vivo model. MATERIALS AND METHODS Four observers who were well trained in color assessment and handling of the dental shade-matching device determined teeth color and CIE-Lab values on maxillary right central incisors in 10 patients with completely healthy and intact den...
