Time Series Forecasting (TSF) is a key tool to support decision making, for instance by producing better estimates to be used when planning production resources. Artificial Neural Networks (ANN) are innate candidates for TSF due to advantages such as nonlinear learning and noise tolerance. The search for the best ANN is a complex task that strongly affects… (More)
The preparation of three carbonates and two carbamates of norethisterone (17 alpha-ethynyl-17 beta-hydroxyestr-4-en-3-one) are described. Due to instability of the carbonates and the very low solubility of the carbamates these compounds could not be submitted to biological testing.
