The most fundamental means of maintaining mechanical safety is to systematically carry out safety design and analysis in the mechanical design process. The fuzzy comprehensive evaluation method is to take the advantages of the level analytic hierarchy process and fuzzy comprehensive evaluation method. Firstly, the evaluation index system is divided into ladder level structure, calculated the index...
Based on TM image data in 1997 and 2005, supported by RS and GIS techniques, seven indices were put forward to analyze the landscape pattern and stability of Jiuzhaigou Nature Reserve, these indices included diversity, dominance, evenness, fragmentation, isolation, fractal dimension and stability index. The results showed that: (1) the numbers and areas of landscape patterns were in the disproportion,...
Human abnormal action is an active issue in the computer vision domain. Most of the current approaches rely on spatio-temporal feature. A great deal of work has been done to show the feature with good performance, but expensive computation. There are some applications with low requirements for human abnormal action detection. We propose a new simple but low computational human abnormal action detection...
In this study, we investigate the customer's sensation to service quality of state-owned commercial bank and the relation between Organizational citizenship behavior (OCB) and service quality. Results suggest that the sensation to service quality of different customers in sex, marriage, age and education is different, the relation between OCB and service quality is significant. Empirical implications...
Aim: To study the effect of Geraniin on the expression of P53 genes in human hepatoma HepG2 cells. Methods: Cell survival was measured using MTT metabolic viability assay. Apoptosis of HepG2 was investigated by DNA gel electrophore; The level of P53 gene expression was measured by reverse transcription polymerase chain reaction (RT-PCR) and Western blotting analysis after the HepG2 cells were treated...
Aim: To study the anti-tumour effect of Geraniin isolated from Agrimonia pilosa ledeb. Methods: MTT was used to study anti-tumor effect of Geraniin in vitro. Morphological observation of the cells was completed by fluorescence microscope. The effect of Gerannin on cell apoptosis in human gastric carcinoma SGC-7901 cells was studied by flow cytometry. Results: The proliferation of SGC-7901 cells was...
In China, the effect of air pollution on human health has been widely concerned and the acknowledge of health effects of air pollution has become the important basis of making related environmental control policies. This paper brought air pollution factors into health production function model and utilized related statistical data to evaluate the effect of air pollution on human health in China. The...
We defined two kinds of Chinese words network (CWN) in this paper. The nodes in the network are composed by the Chinese characters, phrases or classical idioms from authority dictionaries. Studying the network characters and giving a new evolution model to simulate the CWN, we found that the phrase construction follows random and preferential choosing method and we found 55 Chinese characters used...
K-means is a widely-used clustering algorithm in data mining. In traditional algorithm, each feature is treated equally and each one gives the same contribution to K-means. In fact, redundant and irrelevant features may disturb the clustering result. This paper proposes a improved K-means algorithm based on a fuzzy feature selection strategy. The method is based on measuring 'feature important factor'...
Software processes are highly people-dependent and knowledge transfer-centric compared to traditional manufacturing processes. Different people are responsible for different types of knowledge transformation according to the skill set and expertise they master. This adds a great deal of complicated factors in resolving the scheduling problem in software development and maintenance process planning...
