In this article, based on grey relational analysis method, relational polarity analysis for the anti-respiratory syncytial virus effect of compositions from Baikal skullcap root was studied. The compositions with reinforcement effect on the therapeutic index of anti-respiratory syncytial virus were found and ranked.
Base on the Landsat TM/ETM+ data on August of 2001 and 2010, the surface urban heat island (SUHI) intensity on prevailing wind direction belt using three sampling belts with 1 km width within the third circle freeway of Shenyang were calculated, and its relationships with land use types, source-sink distribution, normal differential vegetation index (NDVI), normal differential built-up index (NDBI),...
Journal rankings and journal ratings are important to government, research institutes and scientific research, which use as the criteria for evaluating researcher's performance to determine whether he or she can get a promotion or research funds. The only widely adopted journal assessment method is impact factor, focusing on the citations between academic journals. However, impact factor disregards...
In this paper, approaches to develop subspace-based classifiers for material based signal classification are presented. Material based signal classification is essential in many applications for the identification of the cause of the acoustic signal. Four approaches are presented in this paper for classification. They are namely, classification via eigen-filter characteristics, eigenvector projection...
The electromechanical coupling phenomenon in CNC machine tool has an important influence on the dynamic precision of the feed system. The complicated dynamic characteristics and their evolutions with different parameters will aggravate the research difficulty of the electromechanical coupling mechanism. In this paper, taking SL250 lathe as the research object, the servo torque and mechanical structure...
In view of limitations of students' evaluation on course and lack of evaluation methods on student's comprehensive quality, we put forward the concept of the course suitability and design a set of courses appropriate evaluation index and analysis methods. This concept means that the degree of teaching and learning requirements of universities, which is similar to the Customer Satisfaction in management...
The methods of documentary data collecting, mathematical statistics as well as the grey weight analysis in the grey theory system are used to analyze the influencing factors in the 400m performance. Results indicate that: the time used in the first and fourth 100m of the race exerts great influence for the final result. Therefore, the training method needs to be improved in order to raise the competitiveness...
This paper introduced the quality control and quality assurance tests used during high-speed railway subgrade construction by China and Germany. Through laboratory Proctor compaction tests and in-situ tests using two kinds of filling materials, the correlations between compaction grade used in China and Proctor density used in Germany are obtained. The relations among the porosity, compaction grade...
This thesis puts forward 11 main influence factors which may have impact on the informatization construction by identifying the internal and external influence factors. And this paper processes the surveyed data of 12 enterprises in northeast area based on grey relational analysis according to the gray character of Enterprise's cognitive to some of the influence factors, and it calculates the correlation...
This work deals with the modeling and simulation of the fretting hysteresis loop. Fretting represents a relative cyclic motion between two surfaces, having a non-uniform distribution of local relative displacement at their contact. Fretting damage is a complex contact phenomenon leading to crack initiation and/or material removal. The shape of the fretting hysteresis loop (loop-like variation of the...
It is very important for the military procurement departments to select supplier scientifically. The selection of suppliers has a direct impact on the efficiency of military materials procurement. This paper proposes the gray comprehensive evaluation model based on the analytic hierarchy process and the grey correlation analysis. Firstly, it describes the principle and steps of gray comprehensive...
College Quality Course could effectively development and integrate educational resources. At present, there are different degrees of quality problems in the management of College Quality Course in our country. This article applies the Quality Function Deployment (QFD)to the management of College Quality Course. Based on analyzing the situation of College Quality Course, it clarifies the object of...
Teachers play quite an important role in teaching, and teaching evaluation includes teachers' evaluation. But the traditional teachers evaluation system can not meet the demands of age. So this paper establishes an effective formative evaluation system and applied the AHP theory into this system. Finally, this paper gives an example to demonstrate how to accurately calculate a teacher's teaching ability.
The author have conducted an empirical analysis on the data of Sino-US trade in the period of 2000-2006 with a focus on the level of intra-industry bilateral comparative advantage and international competitiveness using the index of RCA and intra-industry trade. The trade difference in the patterns of specialization observed in China and in the USA, and that the two countries are in a lasting and...
This paper expounds the basic content of Interrelated Tree Method, and builds the Interrelated Tree model of EPC project risk management; On this basis, the paper makes a risk list with the combining methods of qualitative and quantitative analysis and through the prediction and identification of the risk in the EPC project's whole process, and sets up risk assessment index system of all stages of...
Based on the orthogonal test method, optimizing test on softwood cutting propagation technique of Symplocos tetragona has been carried out. The results indicated that cutting type, growth regulator type, growth regulator concentration, and treatment time had significant effect on rooting quality of Symplocos tetragona, and the best level for factors were the upper part of cuttings with terminal buds...
Sequence families with zero or low correlation zone can be used in the quasi-synchronous code-division multiple-access (QS-CDMA) communication systems. Interleaving techniques are very useful for sequence design. In this paper, we present a general construction of sequence families with zero or low correlation zone using interleaving techniques and complex Hadamard matrices. The component sequences...
The location of logistics distribution center holds an very important position in the coal enterprise supply logistics system planning, the decision-makers need to consider various factors comprehensively. The traditional location method considers little about the interaction between the indexes during the location process. This paper introduce the principal component analysis (PCA)method in the location...
In decision-making process, the index weight is identified as a core issue. The traditional correlation index weight determining method requires the experts to give the weights in the form of definite numbers based on experience. But in many cases , the experts in determining weights only give interval grey number weights which including of both certainty and uncertainty. This article, through a certain...
