Objective To analyze the impact of color a resin composite cement (RCC) on optical properties different computer-aided design and manufacturing (CAD/CAM) ceramics. Materials methods Specimens (N = 220, thickness: 0.9 ± 0.03 mm) were fabricated from: leucite (Initial LRF Block/IPS Empress CAD), lithium disilicate (Amber Mill/IPS e.max metasilicate (Celtra Duo), alumina silicate ceramic (n!ce) in...

One of the most perplexing problems confronting device designers utilizing MOS technology is the development of an effective layout design methodology. This paper describes a versatile layout design scheme for customized digital-type MOS arrays utilizing four-phase clocking schemes (ratioless logic). The analytical characterization of this layout design scheme is defined through the introductio...

A general framework of a system that supports building engineering is presented It accounts for a set of desirable features. Among them are (1) graphical man-machine interaction, (2) high interactivity to facilitate the acquisition of the huge amount of knowledge necessary to support design, (3) incremental knowledge acquisition as the basis for incrementally increasing system support, and(4) a...
