As the 750kV substation has the characteristics like incomplete information, uncertain diagnosis result and dual protection configuration, a fault diagnosis method of substation with redundant protection configuration based on rough sets and grey relational analysis is proposed. In this method, the diagnosis decision table which takes advantage of information about wave-recording devices and tw...

In machine learning, multiclass or multi-label classification is the special case within statistical classification of assigning one of several class labels to an input object. The multiclass problem is more complex than binary classification and less researched problem. In biology promoter is the DNA region where the transcription initiation takes place. Reliable recognition of promoter region...

This study investigates a parametric multi-objective optimization of the Tungsten Inert Gas-Metal Gas (TIG-MIG) hybrid welding AISI 1008 mild steel joints. A combined grey relational system theory and Taguchi method was used for process towards achieving set parameter that maximizes both ultimate tensile strength 0.2% yield structural applications. An L-9 orthogonal array based on adopted exper...

This paper presents a novel approach to solve the multi-objective optimization problem designing two-stage helical gearbox by applying Taguchi method and grey relation analysis (GRA). The objective of study is identify optimal main design factors that maximize efficiency minimize mass. To achieve that, five factors. including coefficients wheel face width (CWFW) first second stages, allowable c...

As high-level equipment and advanced technologies continue toward sophistication, ultrasonic technology is extensively used in the polishing process of difficult-to-process materials to achieve efficiently smooth surfaces with nanometer roughness. The silicon carbide, an indispensable difficult-to-machine optical material, extremely challenging due its high hardness good wear resistance. To ove...

Customers are the bedrock of any business and driving force behind its growth. As disparities in manufacturing costs, product quality, management systems between competing companies narrow, meeting customer expectations, increasing satisfaction with company, exceeding expectations has become a robust measure for businesses seeking to increase their competitiveness. While advanced technologies o...

Based on detailed analysis of computational principles of the grey relational analysis method and a series of the relevant researches, this paper proposes a web service selection method based on Grey Relational Analysis to improve the shortcomings caused by personal assignment, so as to improve the usability of the algorithm and reduce the limitation of service selection. At the same time, this...
