This article proposes a Radial Basis Function Artificial Neural Network (RBF-ANN) to classify tempered steel cams as correctly or incorrectly treated pieces by using multi-frequency nondestructive eddy current testing. Impedances at five frequencies between 10 kHz and 300 kHz were employed to perform the binary sorting. The ANalysis Of VAriance (ANOVA) test was employed to check the significanc...

This paper introduces an experimental technique to investigate dynamic friction characteristics of sliding interfaces at normal pressures up to 125 MPa, slip speeds up to 15 m/s and slip distances of approximately 10 mm. This new apparatus involves a novel modification of the conventional torsional Kolsky bar apparatus employed extensively in the past to investigate high-strain-rate behavior of...

The financial comprehensive appraisal method plays an essential role in decision-making for investors and reflecting real company’s financial comprehensive situation. Because of the grey characteristics of financial information, this paper constructs a grey relational model with a index system of financial comprehensive appraisal by grey relation theory. It is applied to listed companies in rea...

Abstract: This paper presents a modeling procedure of discovering emergent chance for decision making based on Analytic Hierarchy Process (AHP) and Grey Relational Analysis (GRA). Firstly, the influencing factors of the chances are obtained from domain experts, and then calculate the weights of these influencing factors. Secondly, we use the grey relational model to grade possible chances in de...

The present work is concentrated with the dry turning of AISI 304 Austenitic Stainless Steel (ASS). This paper presents the influence of cutting parameters like cutting speed, feed rate and depth of cut on the surface roughness of austenitic stainless steel during dry turning. A plan of experiments based on Taguchi’s technique has been used to acquire the data. An orthogonal array, the signal t...

In the published studies, to best of authors’ understanding, grey Taguchi-based statistical technique has not been applied for optimization combined gas-steam power plants. view this, seven essential input parameters namely compressor inlet air temperature, pressure ratio, fuel volumetric flow rate fuel, gas turbine maximum efficiency, and efficiency are chosen with aim determining optimal comb...
