Introduction. Cardiovascular disorders (CVDs) are among the most important diseases in the world and determination of their risk factors is essential for primary and secondary prevention. This study aimed to evaluate these risk factors in workers of tile and ceramic industry, a main industry in Yazd. Materials and Methods. In a cross-sectional study, 1075 tile and ceramic workers were selected ...

nanoparticles classified in 4 overall groups containing: metallic nanoparticles, ceramic nanoparticles, polymeric nanoparticles and semiconductor nanoparticles. these nanoparticles are used in some biomedical applications such as carrying medicine and photographing agents. with attention to different criteria which are both qualitative and quantitative, selecting the most suitable nanoparticles...

This work has the goal to design an automatic system to detect flaws and edge irregularities on ceramic plates. Edge irregularities are detected as well as black spots on both sides of the plates. The detection of defects using photography and image processing techniques allows image interpretation leading to a decision to accept or reject the plates. A special system of lightning was designed....

The ceramic tile industry has evolved greatly in the recent years to the almost complete automation of the production line. After a decade of improvements in the manufacture, today’s plants are capable of mass produce tiles with little human intervention. However, the planning and scheduling of the orders has not changed much and scheduling the client’s orders in the shop remains as a manually ...

Ceramic floor tile systems can provide a durable finish; however, if internal stresses are allowed to accumulate in the tile system, fractured, buckled, and/or hollow-sounding tiles may develop. Using case studies of residential structures, this paper will discuss common perils that cause damage to ceramic floor tile systems and how these perils can be avoided through proper installation and ma...

Intensified environmental regulations have posed numerous challenges in the disposal of industrial wastes. The steel industry is one of the biggest production industries, with a considerable amount of daily wastes. Production of glass-ceramic from the steel industry waters is one of the proper solutions for this problem. In this study, the application utilization of different wastes (such as bl...

Ceramic tiles have become very popular and are used in the flooring of offices and shopping malls. As testing the quality of tiles manually in a highly polluted environment in the manufacturing industry is a laborintensive and time consuming process, analysis is carried out on the tile images. This paper discusses an automated system to detect the defects on the surface of ceramic tiles based o...
