    The Deep-Water Benthic Harpacticoida (Copepoda) of the Americas

    Deep-sea harpacticoid copepods are poorly known worldwide. Due to sampling difficulties, these organisms are seldom captured. Recent investigation, however, has allowed for the discovery of many new species an...

    Benchmark Problem for Assessing Effects of Human-Structure Interaction in Footbridges

    Currently, construction tendencies tend to design flexible structures, such as footbridges, slabs and grandstands, due to the increased resistance of new materials and the regulation gap in building codes. The...

    Knowledge refinement of an expert system using a symbolic-connectionist approach

    In this paper we have shown how to solve a real connectionist learning problem with a symbolic interpretation for the refinement of scoring systems and risk evaluation systems. This is a significant issue not eas...

    Methods for encoding in multilayer feed-forward neural networks

    Neural network techniques for encoding-decoding processes have been developed. The net we have devised can work like a memory retrieval system in the sense of Hopfield, Feinstein and Palmer. Its behaviour for 2 ...
