Conventional magneto-static finite element (FE) analysis of electrical machine design is time-consuming and computationally expensive. Since each topology has a distinct set parameters, optimization commonly performed independently. This article presents novel method for predicting key performance indicators (KPIs) differently parameterized topologies at the same time by mapping high-dimensiona...

Conventional pipeline failure pressure assessment codes do not allow for prediction of interacting defects subjected to combined loadings. Alternatively, numerical approaches may be used; however, they are computationally expensive. In this work, an analytical equation based on finite element analysis the API 5L X52, X65, and X80 corroded pipes with a longitudinal corrosion defect loadings is p...

The rational cubic function with three parameters has been extended to rational bi-cubic function to visualize the shape of regular convex surface data. The rational bi-cubic function involves six parameters in each rectangular patch. Data dependent constraints are derived on four of these parameters to visualize the shape of convex surface data while other two are free to refine the shape of s...

pavement permanent deformations due to lack of shear strength in mixture are a major reason of rutting. any simple test to determine mixtures resistance to permanent deformation isn’t distinguished in the 1st level of superpave mix design method and prevalent methods for evaluating mixture rut resistance are expensive and time-consuming. two aggregate types, gradations, asphalt cements and fill...

Previous studies have shown that differential evolution is an efficient, effective and robust evolutionary optimization method. However, the convergence rate of differential evolution in optimizing a computationally expensive objective function still does not meet all our requirements, and attempting to speed up DE is considered necessary. In this paper, a new local search operation, trigonomet...

Performing reliability analysis on complex systems is often computationally expensive. In particular, when dealing with having high input dimensionality, estimation becomes a daunting task. A popular approach to overcome the problem associated time-consuming and expensive evaluations building surrogate model. However, these efficient models suffer from curse of dimensionality. Hence, training m...

According to Voas et al. testability is defined as the ease with in which faults may manifest themselves as failures when the software undergoes the testing process [39]. They also went further by introducing an approach for measuring sensitivity in terms of estimates from Propagation, Infection, and Execution (PIE) analyses of software and calculating the testability of a program through sensi...
