The liquid metal flow and the solidification behaviours in a multi-cavity casting mould of two automotive cast parts were simulated in three dimensions. The commercial code, FLOW-3D® was used because it can track the front of the molten metal by a Volume of Fluid (VOF) method and allows complicated parts to be modeled by the Fractional Area/Volume Obstacle Representation (FAVOR) meth...

The celebrated Takens' embedding theorem concerns an attractor of a dynamical system in Euclidean space appropriate dimension through generic delay-observation map. also establishes topological conjugacy. In this paper, we show how arbitrary sequence can be mapped into another as attractive solution nonautonomous system. Such mapping entails conjugacy and between the spaces. This result is not ...

Many potential applications for artificial intelligence (AI) in manufacturing extend classical AI in two ways. First, they go beyond modeling a single decision-maker to incorporate the interactions of multiple “agents.” Second, instead of fitting a “problem solving” rubric that seeks to reach achievement goals, they are more aptly cast as “going concerns” that support maintenance goals in the f...
