Incorporating industrial constraints for multiobjective optimization of composite laminates using a GA
In this article, complexities related to the multicriteria (multiobjective) optimization of laminated composite structures subjected to technological constraints will be presented. So, various technological constraints will be presented and a strategy of handling each constraint (in order to use the multi-objective optimization tools based on genetic algorithms) will be also introduced
Clinical factors affecting the translucency of monolithic Y-TZP ceramics
The use of monolithic yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramics in aesthetically critical regions is questionable because of the insufficient translucency and opacity of the restorations. Intrinsic (manufacturing process) and extrinsic factors (laboratory procedures and clinical factors) can affect the translucency of monolithic zirconia. In this narrative review, the clinical factors (thickness, cementation type, colour of the monolithic zirconia, surface finishing methods and wear, dental background, cement colour, low temperature degradation) affecting the translucency of monolithic Y-TZP ceramics were reported
