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...

In a graph G, a vertex dominates itself and its neighbors. A subset S ⊆ V (G) is an m-tuple dominating set if S dominates every vertex of G at least m times, and an m-dominating set if S dominates every vertex of G−S at least m times. The minimum cardinality of a dominating set is γ, of an m-dominating set is γm, and of an m-tuple dominating set is γ×m. For a property π of subsets of V (G), wit...

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...

Real-world data are often uncertain and incomplete. In probabilistic relational data models uncertainty can be modeled on two levels. First by representing the uncertain instance of a tuple by a set of possible instances and second by assigning each tuple with its degree of membership to the considered relation. To overcome incompleteness, data from multiple sources need to be combined. In orde...

Let k be a positive integer. A subset S of V (G) in a graph G is a k-tuple total dominating set of G if every vertex of G has at least k neighbors in S. The k-tuple total domination number γ×k,t(G) of G is the minimum cardinality of a k-tuple total dominating set of G. In this paper for a given graph G with minimum degree at least k, we find some sharp lower and upper bounds on the k-tuple tota...

Service adoption analysis is a useful instrument for reducing the risk of new service development and launch. The purpose of this study is to develop a 2-tuple fuzzy linguistic approach for assessing the intention level of service adoption. In doing so, a theoretical framework for service adoption analysis is proposed. Under this framework, a 2-tuple fuzzy linguistic approach is then proposed f...

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...

this prioritization of the projects in the organization is a multi-criteria decision making (mcdm) that because of the uncertainties existing in experts judgments, these cannot be represented accurately with numbers. the scope of this research is the introduction of the grey system theory (grey possibility degree method) and application in ranking strategic organizational projects in an uncerta...

The construction of the intensity China's inter-provincial economic ties is great significance to spatial carrier modern industrialization system. We uses entropy method, modified gravity model and grey correlation measure linkage in 2019 its influencing factors. research shows that: (1) strength connection network different, not balanced. It mainly concentrated Beijing-Tianjin-Hebei region Jia...
