Abstract: fabricated. Modifications carried out in different parts of the old system in order to control mostof the growth parameters with more accuracy. The fabricated system was used to grow sapphiresingle crystals with almost 10 mm in diameter and 50 mm in length. The crystallinity andstructure of the grown crystals were characterized by computer aided single crystal X-raydiffraction techniq...

Purpose: This study assessed radiopacity of resin-based computer-aided-design/computer-aided-manufacturing (CAD/CAM) materials by areal grayscale pixel value measurement.

Oral cancer is the most common cancer found in both men and women. Early Detection of Oral Cancer is important in saving life. Dental Radiographs assists experts in identifying cancers grown inside the mouth. To help radiologists, Computer Aided Detection and Computer Aided Diagnosis algorithms are developed. The algorithms help to identify cancers by reducing the need for Biopsy. This paper gi...

A new type of detector which we call the Catalytic Activity Aerosol Monitor (CAAM) was investigated towards its capability to detect traces of commonly used industrial catalysts in ambient air in quasi real time. Its metric is defined as the catalytic activity concentration (CAC) expressed per volume of sampled workplace air. We thus propose a new metric which expresses the presence of nanopart...

Computer methodologies are being developed to assist radiologists, as second readers, in the interpretation of mammograms. This could represent further amelioration by increasing diagnostic accuracy in the screening programs. We have developed a computerized scheme to detect clustered microcalcifications in digital mammograms, using 100 mammograms that were randomly selected from the mammograph...

This paper presents a novel craniofacial reconstruction algorithm based on moving least squares deformation. The 3D skull mesh model is obtained with Marching Cube Algorithm, which extract the iso-surface from a complete head CT slice datum. The holes detected in the 3D skull model can be repaired with different methods after the holes are clarifed . Then, the craniofacial is reconstructed usin...
