This paper proposes a refined version of particle swarm optimization technique for the optimum design of steel structures. Swarm is composed of a number of particles and each particle in the swarm represents a candidate solution of the optimum design problem. Design constraints in accordance with ASD-AISC (Allowable Stress Design Code of American Institute of Steel Institution) are imposed by t...

Models of the fluid-particle velocity correlation are evaluated in fully-developed particle-laden turbulent channel flow. The database for the model evaluations is generated using Large-Eddy Simulation (LES) of the carrier phase flow combined with Discrete Particle Simulation (DPS) for the dispersed phase. The current focus is on gas-solid flows for which the particle equation of motion include...

The three-dimensional cranking model is used to investigate the microscopic aspects of the rotation of nuclei with the tetrahedral symmetry. Two classes of rotation axes are studied corresponding to two different discrete symmetries of the rotating hamiltonian. Self-consistent Hartree-Fock-Bogoliubov calculations show that the tetrahedral minimum remains remarkably stable until the first single...

this article presents the application of two algorithms: heuristic big bang-big crunch (hbb-bc) and a heuristic particle swarm ant colony optimization (hpsaco) to discrete optimization of reinforced concrete planar frames subject to combinations of gravity and lateral loads based on aci 318-08 code. the objective function is the total cost of the frame which includes the cost of concrete, formw...

I discuss some new trends in Particle Theory beyond the Standard Model. Some topics which are briefly covered include electroweak baryogenesis, gauge versus non-gauge discrete symmetries, the strong-CP problem, dynamical symmetry breaking scenarios, supersymmetric grand unification, new aspects in low-energy supersymmetry and superstring phe-

The National Health Service (NHS) constitution sets out minimum standards for rights of access patients to NHS services. ‘Faster Diagnosis Standard’ (FDS) states that 75% should be told whether they have a diagnosis cancer or not within 28 days an urgent GP referral. Timely and treatment lead improved outcomes patients, however, compliance with these has recently been challenged, particularly i...
