In the software quality modeling process, many practitioners often ignore problems such as high dimensionality and class imbalance that exist in data repositories. They directly use the available set of software metrics to build classification models without regard to the condition of the underlying software measurement data, leading to a decline in prediction performance and extension of train...

simulation of grinding circuits has being performed from 30 years ago and is also to be more complete and powerful approach with improvement of mathematical models which simulate various processing units/machines. the modeling and simulation of various mineral processing circuits are presently performed. in order to simulate the present grinding circuits of esfordi phosphate processing plant, a...
