The work described here was largely performed at a medium-sized European steel mill, with an unusually diverse product portfolio, and hence a difficult scheduling problem to solve. The decision support system developed as a result has been successfully used, with minor modifications, at many steel mills worldwide. The work was carried out while the author was employed at A. I. Systems, Belgium,...

the asymptotically ads solutions of the einstein gravity with hyperbolic horizons in the presence of so(n(n-1)/2- 1,1) yang-mills fields governed by the non-abelian born-infeld lagrangian are presented. we investigate the properties of these solutions as well as their asymptotic behavior in various dimensions. the properties of these kinds of solutions are like the einstein-yang-mills solutions...

the mean noise levels were measured in the different sections of six representative mills in the isfahan area, and audiometric measurements were made in 282 male workers employed in these mills. the mean noise levels were on average 95 dba in the weaving sections and 88 d ba in the spinning sections. the audiometric findings showed a significant loss of gearing in the textile workers as compare...

The quality of steelwork products depends on the geometric precision flat products. Heavy-plate rolling mills produce plates for large-diameter pipes and use in shipbuilding, mechanical engineering, construction. This is why requirements are so stringent. Today’s Mills 5000 up to 5 m width; operation these units shows ‘camber’ defects axial shift roll at stand exit point. induces greater loss m...

Abstract The use of wire arc additive manufacturing (WAAM) in conjunction with topology optimisation enables the production structural components significantly higher strength‐to‐weight ratios than conventional components. However, owing to additional stages involved WAAM ( e.g . welding), a common question arises regarding environmental impacts using produce relative fabrication techniques hot...
