Temperature vegetation dryness index (TVDI) is widely used for its physical significance. In this study, using the historical MODIS data, we consider Henan Province, a large grain province in Central China, an example for constructing feature space and calculating TVDI. Multi- and single-group image approaches are then compared, and the applicability of the TVDI in Henan Province is analyzed through...
This article researches on node importance ranking of multiplex network. Existing node importance ranking methods are amost monoplex network using only single relationship. However, in real life a person often has various relationships, so how to rank nodes of multiplex network is more realistic and meaningful. In this article, we propose a multiplex network node ranking method based on weighted aggregation...
Recurring to well-rounded fuzzy theory and technology can realize exact expression and manage between imprecise information and imprecise relation on water-bursting prediction. Advanced a method combining the fuzzy cluster analysis and fuzzy pattern recognition to forecast deep seam mining floor water-bursting. Firstly, the simple integration is classified for the water-bursting by adopting clustering...
This paper studies synthetic evaluation method of emergency logistics network schemes in the economic, technical and social aspects. The significance of each evaluation index is evaluated by using the expert evaluation system. Through the combination of Analysis Hierarchy Process and Entropy Technology, the AHP-Entropy Decision Model is established to synthetically evaluate the preinstalled emergency...
In electricity market environment, power generation, transmission and consumption become self-governed economy entities. The change of supply and demand for these market partners can result in the need for automatic generation control (AGC) ancillary service. So the AGC cost should be allocated among them. In our country, the amount of AGC is ascertained on the base of the control area, it is difficult...
Unstable angina (UA) is now a severe burden on society and family in both industrialized and developing countries, but the traditional related factors can not explain the whole situations. The effect of treatment is very limited. Determination of treatment based on the symptoms and signs in Traditional Chinese Medicine (TCM) have certain curative effect. But the objective of the syndrome diagnose...
Network security situation is a hot research realm in the area of network security, which helps security analysts to solve the challenges they encounter. This paper presents the evaluation index, and the characteristic attributes to describe the state of network situation, discusses the grey model includes grey correlation model and grey forecast algorithm to get the evaluation index and predication...
Concerning the images of low contrast ratio, this paper presents a new defining approach for the partial contrast ratio. A new enhancement exponential function is used to measure the enhancement degree, while the fuzzy entropy is taken to weigh the partial detailed information. Given the entire contrast information, the enhancement index is determined, and then the fuzzy contrast transformation is...
Logistics service level and logistics cost are in contradiction while they are also in inter-linkage unity from empirical aspect. Through analyzing the game relationship between enterprise logistics service level and logistics cost, the function relationship between logistics service level and logistics cost (sales income) is simulated with the help of the least square method. Basing on these, the...
In this paper we study on the prediction technique of network situation awareness. It has two levels: the high-level situation and the low-level next attack step. The first one includes the indexes and the evaluation results of the network security situation, they are figure form, we use the RBF network to predict them for RBFpsilas self-learning character. Then we use the weighted attack graph to...
Economy going global has been an unchanged trend and Chinese enterprises of course canpsilat go this way smoothly. During this, cultural integration is a relatively complicated segment. This article starts out with Hollandpsilas scholar, Geert Hofstedepsilas view about the national culture model, which is called Geert Hofstedepsilas Model. According to it, the author sets up a model for Chinese national...
