In several experiments, it was found that global perception of spatial form can arise exclusively from unpredictable but synchronized changes among local features. Within an array of nonoverlapping apertures, contours move in one of two directions, with direction reversing randomly over time. When contours within a region of the array reverse directions in synchrony, they stand out conspicuousl...

Purpose. Experimental study on microstructure, mechanical properties of pipe diversity a new type cold rolling pipe, which has the ability to perform different modes supply and rotation. Methodology. Research method is an experimental one modern industrial equipment using devices. The was conducted when pipes made steel 08Cr18Mn10Ti CRP 6-20 mills. Rolling route often 25 × 2.5 mm ® 16 1.5 mm, u...

Lubrication in the cold rolling process plays a key role withstanding loads between strip and work rolls, as well ensuring high surface quality, tight geometric tolerances, large thickness reductions. Most of currently used lubricants have synthetic or semi-synthetic formulations, but research for greener alternatives, able to guarantee very low environmental impact during both preparation (use...

The Coastal area of Nazhvan is located at the riverside of Zayandehrūd River in the western part of Isfahan. In the gardens of this area which are mostly orchards, woodlands full of fruitless trees, owners have constructed architectural spaces and pavilions. One of the prominent architectural spaces within this territory is a mill known as “Asyāb-e Nazhvān or Hājjī”. There stands a two-floor pa...
