Published in 2018 at "Journal of Mathematical Sciences"

DOI: 10.1007/s10958-018-4129-x

Abstract: We enumerate maximal chord diagrams up to all isomorphisms. The enumeration formula is based on a bijection between the rooted one-vertex one-face maps on locally orientable surfaces and a certain class of symmetric chord diagrams.… read more here.

Published in 2020 at "Engineering Structures"

DOI: 10.1016/j.engstruct.2019.110052

Abstract: Abstract Internationally representative steel design standards imposed restrictions on tubular joints fabricated from high-strength steels, and this is partly due to concerns regarding their unique material characteristics, such as high yield ratio and low deformability.… read more here.

Published in 2021 at "Structures"

DOI: 10.1016/j.istruc.2021.01.065

Abstract: Abstract Axial load-resisting capacity of a cold-formed steel (CFS) built-up laced column primarily depends on the unbraced chord slenderness, slenderness ratio of lacings, overall slenderness ratio, and geometry of column sections. Unlike hot-rolled steel built-up… read more here.
