The study of classification of types of glass was motivated by criminological investigation. At the scene of the crime, the glass left can be used as evidence... WebThe structure of our paper is as follows: in Section 2 we discuss the rationale and prediction methods behind current early warning systems. In Section 3 we outline our approach to developing an accurate prediction method for an early warning system. We extend current research on the development of early warning systems through: using ‘new ...
