The paper presents the application of augmented reality to support product design and development. The paper concentrates on a new engineering tool. By this reason design and its issues are presented in a very limited way. The goal of the research was to improve design process and reduce product development time. The presented system bases on CAD software which is integrated with an expert syst...

AIM To review the adhesive bonding to different computer-aided design/computer-aided manufacturing (CAD/CAM) esthetic restorative materials. BACKGROUND The use of CAD/CAM esthetic restorative materials has gained popularity in recent years. Several CAD/ CAM esthetic restorative materials are commercially available. Adhesive bonding is a major determinant of success of CAD/ CAM restorations. R...

often in modeling the engineering optimization design problems, the value of objective function(s) is not clearly defined in terms of design variables. instead it is obtained by some numerical analysis such as fe structural analysis, fluid mechanic analysis, and thermodynamic analysis, etc. yet, the numerical analyses are considerably time consuming to obtain the final value of objective functi...

background: there have been numerous researches on elastomeric ligatures, but clinical conditions in different stages of treatment are not exactly similar to laboratory conditions. the aim of this in vitro study was to simulate clinical conditions and evaluate the effect of three stretching patterns on the amount of force, tensile strength (ts) and extension to ts of the elastomers during 8 wee...

The surge of modern techniques to fabricate structured materials paired with our ever deeper understanding of complex forms ofmatter present uswith the opportunity tomake and study dramatically new forms of designed materials and structures. This movement is being fueled by recent and rapid developments in a variety of fields, including soft matter, materials science, computer assisted design a...
