Finally, we'll also want to get the logical coordinates of the mouse pointer, and we do this with the ElementToLogicalPoint API call, passing the current mouse position (which can be de-rived from the MouseEventArgs object that is passed to this function) and then loading the re-sults into the pLast variable.

A model for predicting the sulphur content in hot metal based on neural networks is introduced. Blast temperature, blast flux, top temperature, burden, coal injection rate, sulphur content in ore, sulphur content in coke, sulphur content in coal and silicon content of last tap were selected as inputs. The inputs were treated with time lag to improve prediction.
