Abstract Unlike older design codes, Eurocode 2 does not provide a procedure for calculation of the capacity axially loaded columns. For that purpose, general algorithm is developed, using principles structural mechanics and mathematics: It starts with constructing P-Δ relationship (buckling curve) element, accounting initial imperfections, minimum eccentricity, material nonlinearity second orde...

We study linear torsional Alfvén waves in a magnetic flux tube with an arbitrary cross-section. assume that the equilibrium field is propagating z-direction Cartesian coordinates x,y, and z. The cross-section bounded by smooth closed curve. Both plasma are homogeneous outside this magnitude function of x y, while density product two functions: one dependent on z other y. As result, speed also e...

Building surfaces from cross-section curves has wide applications including bio-medical modeling. Previous work in this area has mostly focused on connecting simple closed curves on parallel cross-sections. Here we consider the more general problem where input data may lie on non-parallel cross-sections and consist of curve networks that represent the segmentation of the underlying object by di...

We briefly describe a new general algorithm for carrying out QCD calculations to next-to-leading order in perturbation theory. The algorithm can be used for computing arbitrary jet cross sections in arbitrary processes and can be straightforwardly implemented in general purpose Monte Carlo programs. We show numerical results for the specific case of jet cross sections in deep inelastic scatteri...

We give a geometric interpretation of the entropy of the supertubes with fixed conserved charges and angular momenta in two different approaches using the DBI action and the supermembrane theory. By counting the geometrically allowed microstates, it is shown that both the methods give consistent result on the entropy. In doing so, we make the connection to the gravity microstates clear. 1 Intro...
