We use relaxation to produce painted imagery from images and video. An energy function is first specified; a painting is then generated by performing a search for a painting with minimal energy. The appeal of this strategy is that, ideally, we need only specify what we want, not how to directly compute it. Because the energy function is very difficult to optimize, we use a relaxation algorithm ...

In pursuit of flexibility and agility within discrete manufacturing, the surrounding logistics and handling processes of a paint shop is under construction as a laboratory prototype application. Holonic Manufacturing seems to be a promising strategic paradigm and architecture to use for a system characterised by production logistics and control. This paper describes the physical devices to be u...

   In this research, mesoporous silica was served as the host of molybdate (corrosion inhibitor). The loaded mesoporous silica was dispersed in a paint matrix. The composite was then coated on the carbon steel surface. Polarization and electrochemical impedance spectroscopy (EIS) tests showed that the corrosion resistance of the scratched paint containing molybdate loaded mesoporous silica ...

Corrosion is one of the biggest problems which affects economy country, occurs as a result interaction metal with its surroundings. One easiest ways to prevent corrosion coatings metals paint, plastic or wood. Several types have been adopted by scientists in prevention that are mainly based on electrochemical principles. Fortunately, cost and effectiveness, four variably employed metallurgy ind...
