GB PavementMat
An AI-based software for prediction of pavement material properties
During pavement quality control, numerous laboratory tests such as California Bearing Ratio (CBR), Proctor compaction test, and Plasticity Index (PI) are conducted to evaluate material performance and suitability. GB PavementMat leverages advanced AI-based models developed using artificial neural networks to accurately predict these critical properties directly from sieve analysis data. This significantly reduces laboratory testing time, cost, and delays while maintaining high reliability.... -

jEPlus - Parametrics for E+ and TRNSYS
An EnergyPlus shell for parametric studies and more ...
Parametric analysis is often needed for exploring design options, especially when a global optimization method is not available, or the optimization result is in doubt. Parametric analysis can also be applied to all design variables simultaneously, which forms an exhaustive search that, providing that the search grid is fine enough, will guarantee a global optimum solution. In order to perform complex parametric analyses on multiple parameters with more than a handful of alternative values... -
