To reveal the stable bearing capacity of a new semi-rigid dome structure, tensile–beam cable (TBCD), detailed numerical simulation and analysis 60 m model TBCD is conducted. Then, effects factors such as prestress level, original imperfection size, distribution, addition hoop tension rods on stability are investigated. The results show that unstable loads arranged from small to large in followi...

The finite element model-based design of steel structures is getting increasing attention by designers, especially in the case buckling problems welded plated and static check interacting stability behaviour. FEM-based approach introduced standardised EN 1993–1-5 Annex C providing ability to calculate resistance based on direct geometrical material non-linear analysis using imperfections (GMNIA...

We are interested in a version of graph colouring where there is a ‘co-site’ constraint value k. Given a graph G with a non-negative integral demand xv at each node v, we must assign xv positive integers (colours) to each node v such that the same integer is never assigned to adjacent nodes, and two distinct integers assigned to a single node differ by at least k. The aim is to minimise the spa...

Carbon Nanotube Field Effect Transistors (CNFETs), consisting of semiconducting single-walled Carbon Nanotubes (CNTs), show great promise as extensions to silicon CMOS and in large-area electronics. While there has been significant progress at a single-device level, a major gap exists between such results and their transformation into VLSI CNFET technologies. Major CNFET technology challenges i...
