A mathematical approach to solve the porthole die design problem is achieved by statistical analysis of a large amount geometric data successful designs. Linear and logarithmic regression are used analyse geometrical 596 different ports from 88 first trial dies. Non-significant variables or high correlated discarded according knowledge extrusion process criteria. This paper focuses on validatio...

The finite volume method is a popular method for the solution of systems of partial differential equations whenever local conservation properties are desired. However, engineering software usually does not reflect the underlying continuous mathematical formulation internally, but instead implements the discrete system directly, sacrificing a higher-level representation. As a consequence, the di...

Researchers have developed artificially intelligent (AI) and expert systems (ES) to assist in the formulation, solution and interpretation of generic mathematical programs (MP). In addition, re­ searchers also have built domain-specific systems either modeled around a mathematical program or which include a mathematical program module. In these systems, the specificity of the domain allows rese...
