recommendations! 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.

DOI: 10.1007/s40430-019-1618-x

Abstract: The main objectives of this study are to investigate parametrically the possible use of alternative airfoils (Joukowski and Göttingen) for propellers and to assess the effects of varying the chord and pitch angle distributions as… read more here.

DOI: 10.1016/j.engstruct.2018.03.061

Abstract: Abstract This research focuses on the structural behaviors of partially concrete-filled welded integral T-joints in steel truss bridges. The T-shape integral joints, which are composed of welded box-section members, were simply supported at chord ends… read more here.

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.

DOI: 10.1016/j.ijheatmasstransfer.2018.12.079

Abstract: Abstract Endwall film cooling investigations were carried out in a four-passage linear turbine vane cascade. The endwall film cooling is designed with two cooling-hole configurations: the mid-chord row and the downstream row. Two-row of staggered… read more here.

recommendations! 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.

recommendations! Published in 2019 at "Journal of Constructional Steel Research"

DOI: 10.1016/j.jcsr.2019.105854

Abstract: Abstract For galvanizing of welded tubular steel trusses, sufficiently large holes to allow for quick filling, venting and drainage must be specified to mitigate the risk of damage. These holes, quite often specified at the… read more here.
