Stainless steel square tube components with complex spatial shapes are widely used in the fields of vehicles, ships, construction machinery and construction. Due to these components tend to be diversified in shape, the ordinary three-axis free bend-ing technology can not keep up with the...

In this paper, we compare the properties of the traditional additive-based data envelopment analysis (hereafter, referred to as DEA) models and propose two generalized DEA models,<i> i.e.</i>, the big M additive-based DEA (hereafter, referred to as BMA) model and the big M additive-based...

While DSS development methodologies and implementation research are abound in the DSS literature, a gap still exists in terms of the ability to provide a holistic conceptual structure for improving the management and development of decision support systems, the ability to capture and share...

In order to improve the high-temperature behaviors of hot work die steel in engineering application, the high-temperature wear and thermal fatigue behavior of brush plating Ni/nano-SiO2 composite coating have been investigated. The microstructure of Ni/nano-SiO2 composite coating has been...
