Machine learning models are built to predict the strain values for which edge cracking occurs in hole expansion tests. The samples from this test play role of sheet metal components be manufactured, often associated with a uniaxial tension stress state at critical edges components. For construction models, dataset was obtained experimentally rolled ferritic carbon steel sheets different qualiti...

Cold denaturation is a general phenomenon in globular proteins, and the associated cold-denatured states of proteins have important fundamental and practical significance. Here, we have characterized the cold-denatured state of a beta-hairpin forming peptide, MrH3a, in 8% hexafluoro-2-propanol (HFIP) and the dynamics of its refolding following a laser-induced T-jump. Beta-hairpins constitute an...

geopolitical imagination, by definition, is the competition between powers in forming individuals’, institutions’ and political factors’ perception of the characteristics and contents of geographical space, on the basis of their intended interests. in this article, as a case study, the us perception of the :union: of soviet socialist republics during the cold war era is analysed. the authors ar...

In search for new manufacturing process, Single Point Incremental Forming (SPIF) emerged to be one of the useful processes for forming complicated shapes. This is a flexible forming process which eliminates the die, punch and errors due to them. It is widely used for batch production of different shapes which has applications in diverse fields like automobile, aerospace, medical industry, packa...
