Abstract. The Ant Colony Optimization Algorithm (ACOA) is a new class of stochastic search algorithm proposed for the solution of combinatorial optimisation problems. Di erent versions of ACOA are developed and used with ...

Abstract. The nature of High Strength Concrete, HSC, is brittle failure and although the behavior of reinforced concrete beams heavily steel reinforced are increased in strength, the ductility, which is important in ...

Abstract. New penalty functions, which have better convergence properties, as compared to the commonly used exterior and interior penalty functions, have been proposed in this paper. The convergence behavior and accuracy ...

Abstract. This paper presents an application of the Max-Min Ant System for optimal operation of reservoirs using three di erent formulations. Ant colony optimization algorithms are a meta-heuristic approach initially ...

Abstract. An experimental investigation of the strengthening of the torsional resistance of High- Strength Concrete (HSC) beams using Carbon-Fiber-Reinforced-Polymers (CFRP) is conducted. A total of seven beams are tested. ...

Abstract. The numerical solution of incompressible Navier-Stokes equations for ows involving complex geometries is greatly a ected by mesh resolution. In these ows, some regions may need ner mesh than others. Adaptive ...
