This study investigated electric arc furnace dust (EAFD) reuse as a raw material in concrete mixes. A comprehensive experimental program consisting of two phases of testing was carried out. The first phase included the replacement of ordinary Portland (Type I) cement by unsieved dust with the percentages of 0, 2.5, 5, 7.5 and 10%. The second phase included the replacement of quartz (filler) by ...

This paper presents a neural network tree regression system with dynamic optimization of input variable transformations and post-training optimization. The decision tree consists of MLP neural networks, which optimize the split points and at the leaf level predict final outputs. The system is designed for regression problems of big and complex datasets. It was applied to the problem of steel te...
