Many real-world manufacturing problems are too complex to be modelled analytically. In these scenarios simulation-based optimisation is a powerful tool to determine optimal system settings. While traditional optimisation methods have been unable to cope with the complexities of many real-world problems approached by simulation, soft computing techniques have proven to be highly useful. This pap...

Aero-engine exhaust gas temperature margin (EGTM) is one of the main indexes engine replacement; however, application existing methods in EGTM forecasting restricted because limited prediction accuracy and many non-linearities. In this study, an adaptive-tunable-based hybrid radial basis function (RBF) network proposed to improve aero-engine EGTM. Firstly, a RBF consisting linear regression mod...

Gaussian beam superposition is applied to model representative standard transducers, which are used in aero engine disk inspection. Previously published approaches available in the literature have been applied and modified to account for rectangular and non-planar transducer apertures. Beam field calculation for both single and layered media is addressed.

In this research, the selective flotation of galena and sphalerite minerals was evaluated from a pyrite-rich lead-zinc sample. An optimum mixture of selective collectors against pyrite and also organic/inorganic pyrite depressants was obtained in the flotation of galena and sphalerite by an experimental mixture design. The effect of different collectors and pH values were investigated in the ob...
