    Abstract: Traditional methods of designing channels of turbomachines are focused on the use of simple geometric lines and surfaces, such as a straight line, arc, plane, cylindrical surface, etc. The design is performed according to recommendations based on experimental data. The other way of designing the channels of turbomachines is related to solving the i... Show More

    Abstract: This study aims to implement the conformal cooling in die casting dies to reduce the cycle time and rejections due to shrinkage porosity. In this paper we have done a flow simulation between conventional cooling and conformal cooling to optimize the cooling time/solidification time reduction and shrinkage porosity reduction in die casting parts whe...

    Abstract: This study presents a precise prediction model that can be applied to model-based control logic for the realization of autonomous driving systems (ADS) for bus rapid transit (BRT; articulated buses). When realizing model-based control logic, the more a prediction model is accurate, the greater that control logic will be the robustness. However, a h... Show More

    Abstract: The syntheses and characterisations of Rare-Earth-Metals (REMs) complexes, via the use of green organic esters such as Pyridinecarboxylate (Pyc) and hydroxylnaphthoate (Hnp) to form stable compounds ie. Lanthanide-hydroxylnaphthoate (Ln-Hnp), have been demonstrated to be the most preferred compounds to form a good protective-film over steel-alloys.... Show More
