Although the overwhelming majority of dental offices now use digital radiography and patient records, relatively few yet use either stand-alone intraoral scanning systems (6%) or complete systems that combine intraoral scanning with computer-aided design and computer-aided manufacturing (12%). This should change as dentists become more aware of the numerous advantages scanning systems offer in ...

A 1-bit digital reconfigurable reflective metasurface (RRM) with 20 × 20 cells is presented, fabricated and measured for beam-scanning performance in this paper. The cell is designed with a single layer structure and one varactor diode, controlled electronically. The cell’s phase compensation is over 180◦ between 3 GHz and 4 GHz and the two states with 180◦ phase difference are selected as codi...

objective(s): nanoparticles (nps) are known for their specific accumulation in the inflamed tissues of the colon and thus allow a selective delivery to the site of inflammation with minimum adverse effects. the main objective of this work is to attain mesalamine loaded chitosan nanoparticles as a carrier for oral delivery. methods: in this study, mesalamine loaded chitosan nanoparticles were pr...

PRISM is a focal point of interdisciplinary research in geometric modeling, computer graphics and visualization at Arizona State University. Many projects in the last ten years have involved laser scanning, geometric modeling and feature extraction from such data as archaeological vessels, bones, human faces, etc. This paper gives a brief overview of a recently completed project on the 3D recon...

Three dimensional architectural models are more and more important for a large number of applications. Specialists look for faster and more precise ways to generate them. This paper discusses methods to combine methodologies for handling data acquired from multiple sources: maps, terrestrial laser and additional measurements, together with digital images for the purpose of generating the 3D vis...

Abstract The primary aim of the present study is to explore use, advantages and potential two advanced data acquisition techniques – 3D scanning digital image correlation (DIC), in testing metallic structures. a novel method for capturing full outer geometry an object. It being increasingly used experimental studies determination dimensional parameters characterisation local global imperfection...

This dissertation investigates the feasibility of using the same digital profile images of fruit that are used in commercial packing houses for colour sorting and blemish detection purposes to estimate the volumes of the corresponding individual pieces of fruit. Data sets of actual fruit volumes and digital images of the fruit that simulate both single and multiple camera set-ups are obtained. ...
