We present transport measurements of ferromagnetically contacted carbon nanotubes. In both singleand multi-walled nanotube devices, a spin valve effect is observed due to spin-polarized transport. In one single-walled nanotube device, the spin-valve effect is suppressed as the influence of Coulomb charging is observed at around 10 K. To help understand the interplay between the Coulomb charging...

In modern offshore installations, thin walled columns are used for energy absorption in accident situation. When this advanced offshore shock absorber is subjected to axial compressive load, plastic hinges are developed on the sides of column and the column crushes with repeatable patterns. It can absorb considerable impact energy due to large and continuous plastic deformation. This paper deve...

This paper presents a fuzzy procedure for obtaining optimal design of channel section shapes under bending moment. The proposed approach refers to an ideal, equivalent single objective representation for the bicriteria objectives, where the cross-sectional area of thin-walled beam is the first objective, while the deflection of the beam is the second one. The design variables were selected as t...
