Imperfections In Calculations Of Guyed Lattice Masts

Optimization of tall guyed masts using genetic algorithms

The aim of the article is to describe the procedure for mixed topology-size optimization of tall guyed masts, seeking the minimal mast weight with stochastic genetic algorithms. Given the height, geometrical in-plan and bracing schemes of the mast, loading and material data, the optimization procedure renders the explicit design of the mast including dimensions of all mast elements, attachment ...

Modelling of Random Geometrical Imperfections and Reliability Calculations for Thin Cylindrical Shell Subjected to Lateral Pressure

It is well known that it is very difficult to manufacture perfect thin cylindrical shell. Initial geometrical imperfections existing in the shell structure is one of the main determining factor for load bearing capacity of thin cylindrical shell under uniform lateral pressure. As these imperfections are random, the strength of same size cylindrical shell will also random and a statistical metho...

Few-Body Lattice Calculations

I will discuss the recent progress toward computing few-body observables using numerical lattice techniques. The focus is overwhelmingly on the latest results from lattice QCD calculations. I present preliminary results from a lattice calculation of the central and tensor potentials between B-mesons in the heavy-quark limit.

Lattice Calculations of Decay Constants

Lattice attempts to compute the leptonic decay constants of heavy-light pseu-doscalar mesons are described. I give a short historical overview of such attempts and then discuss some current calculations. I focus on three of the most important sources of systematic error: the extrapolation to the continuum, the chiral extrapolation in light quark mass, and the eeects of quenching. I brieey discu...
