When it is necessary to evaluate, with a probabilistic approach, the interaction of urban tunnels neighboring structures, computational power an important challenge for numerical models. Thus, intelligent sampling algorithms can be allies in obtaining better knowledge result’s domain, even if possession smaller number samples. In any case, when limited, evaluation risks also restricted. this co...

Chancroid is a highly infectious and curable sexually transmitted disease caused by the bacterium Haemophilus Ducreyl (also known as H. Ducreyl). A deterministic mathematical model for investigating the role of treatment on controlling chancroid epidemic is formulated and rigorously analyzed. A threshold quantity known as the productive number, which measures the number of secondary infections ...

Although Genetic algorithm (GA), Ant colony (AC) and Particle swarm optimization algorithm (PSO) have already been extended to various types of engineering problems, the effects of initial sampling beside constraints in the efficiency of algorithms, is still an interesting field. In this paper we show that, initial sampling with a special series of constraints play an important role in the conv...

We propose symmetric Latin hypercubes for designs of computer exepriment. The goal is to ooer a compromise between computing eeort and design opti-mality. The proposed class of designs has some advantages over the regular Latin hypercube design with respect to criteria such as entropy and the minimum intersite distance. An exchange algorithm is proposed for constructing optimal symmetric Latin ...
