Determining the intelligibilities of filtered speech with various spectrum regions is of great significance for communication research and applications. The importance of different spectral components upon the speech intelligibility for western languages has been studied extensively, but not for Chinese. The current study investigated the relative spectral contributions of Chinese Mandarin sentences...
Traditional process capability indices require that quality characteristics follow normal distribution. But in the actual production processes, quality characteristic usually has a non-normal distribution and almost all the production processes exhibit the between batch variability besides the within batch variability. This paper proposed confidence intervals for process capability indices for log-normal...
To explore the genus Bougainvilleaclassification criteria, comparative analysis of 15 morphological traits collected 18 varieties of Bougainvillea, in order to provide a reference for the promotion of Bougainvillea cultivation, breeding and classification, identification and other research. Q-type clustering results showed that 18Bougainvillea varieties can be divided into 3 categories, including...
In order to solve the complexity of the evaluation process of the urban water supply performance and the drawbacks that data envelopment analysis (DEA) can not be re-sort for effective decision making units, a supper efficiency-data envelopment analysis (SE-DEA) model based comprehensive decision-making scheme for the urban water supply performance is established and a set of options to reflect the...
Based on abundant data of the civil servant performance appraisal systems home and abroad, the authors make comparison and analysis the Chinese and foreign systems, attempting to give an account of the advantages and disadvantages of China's civil servant performance appraisal system after summarizing the relevant appraisal indicators and evaluation methodology of the system in China. What are in...
This paper uses fuzzy neural network method to establish simulation model about the evaluations of customers' beer tastes and preference degree. It explains the methods of building, training and simulating networks in the development environment of MATLAB software. And it does network training and error testing by the actual data to prove this model is feasible.
Public transport is one of most complicated systems in a modern city. Based on the grey system theory, a grey relational assessment model on service quality of urban public transport is put forward. On the Basis of above, this method is applied to evaluate the service quality of public transport in one northern city.
Searching in unstructured peer-to-peer network with scalability and effectiveness is still a challenging problem. Recently in many applications, one-hop index replication becomes a fundamental technique for improving the search performance. However, when we extend one-hop index replication to multiple hops for locating both popular contents and rare objects with high lookup success rate, index storage...
With the rapid development of the information technology and knowledge economy, the old fashioned, traditional service industry manage to make a significant progress to grow into a brand new formation. Now the information amount on the Internet expands in a incredible way everyday, which makes how to keep and manage those information of a mass storage system more and more important for us. So in this...
This paper analyses the characteristics of village community in the city before transformation firstly, and puts forward the aim of community construction in transformation of village in the city. Then this paper points out methods of constructing harmonious community in village in the city from different aspects. Based on the grey system theory, this paper establishes dynamic evaluating model of...
