After doing research on fiber image with low quality and the Grey prediction model, the Grey correlation degree, directed graph and existing edge detection algorithm is addressed and this article proposed a new edge detection algorithm to obtain complete and continuous edge and to improve the defects in traditional operators profiled fiber contour extraction, such as the discontinuous edge, the...

the aim of this paper is to present the prediction model of the transport energy demand in iran. markov chain grey model (mcgm) is proposed to forecast the transport energy demand of iran. then it is compared with grey model (gm) and regression model. moreover, the mcgm forecasting model is used to forecast the annual gasoline demand of iran up to the year 1400. the aim of this paper is to pres...

Abstract In this study, the effects of cutting speed, tool geometry, and machining parameters on surface roughness forces in turning Nilo 36 superalloy have been investigated. An experimental design process was made with Taguchi technique. way, optimum values were estimated a small number experiments. The grey correlation analysis method used to determine best parameter levels plausible factors...

Energy efficiency evaluation of industrial park customers is carried out to help develop optimization strategies and improve the energy level. The indexes are proposed based on pressure-state-response (PSR) model redundant selected by combining principal component analysis (PCA) correlation analysis. Thus dynamic index system constructed. weight calculated entropy method (EWM). An improved Grey...

Human behavior has the positive and negative impact on ecosystem. To study the interaction between ecosystem and behavior system, per-capita energy ecological footprint (EEF) is selected as the ecosystem threshold. Elasticity coefficient of environmental investment (ECEI) and elasticity coefficient of energy consumption (ECEC) represent the positive and negative human impact on ecosystem, respe...

Variations in offset print quality relate to numerous parameters of printing press and paper. To maintain constant quality of products, press operators need to assess, explore and monitor print quality. This paper presents a novel system for assessing and predicting values of print quality attributes, where the adopted, random forests (RF)-based, modeling approach also allows quantifying the in...

With Grey relational analysis (GRA), the paper examined the sensitivity of eight variables influencing test performance at branch level. The eight variables involved included language proficiency, test anxiety, self-esteem, achievement motivation, achievement goal, English proficiency test anxiety (EPTA), state anxiety and trait anxiety. Results showed that: (a) Besides language proficiency, mo...

Multimodal medical images are often of too different a nature to be registered on the basis of the image grey values only. It is the purpose of this chapter to construct operators that extract similar structures from these images that will enable registration by simple grey value based methods, such as optimization of cross-correlation. These operators can be constructed using only basic morpho...

This paper aims to combine grey correlation analysis and response surface method propose a fast effective performance optimization for PEMFC. First, based on orthogonal test data, is used select four variables that have significant influence PEMFC’s comprehensive from eight common parameters. Secondly, analysis, the multi-objective problem transformed into single objective about degree, applyin...
