In recent years, the manufacturing industry of distribution transformer (DT) in China develops rapidly with high competition. Since the pass rates of National Surveillance Sampling in China (NSSC) for DTs keep a low level, the quality is worried. During the 13th Five-Year Plan period, the investment of distribution network construction will reach 1.7 trillion RMB, which makes a big market for DTs...
Modeling and measuring social influence is a major problem in Social Network Analysis. Existing models and methods could handle individual influence analysis conveniently, but they rarely estimate the social influence of communities which are ubiquitous in social networks. Based on the structures of online social networks, a community oriented influence analysis model is proposed. Then, we provide...
Datasets gathered from sensor networks often suffer from a significant fraction of missing data, due to issues such as communication and sensor interference, power depletion, and hardware failure. Many standard data analysis tools such as classification engines, time-sequence pattern analysis modules, and statistical tools are ill-equipped to deal with missing values — hence, there is a vital need...
Study on energy consumption in wireless systems becomes attractive recently. The worldwide organization 3GPP has established a series of standards to help reduce energy consumption in wireless systems. However, the utilization of green related techniques is still in theoretical way. To reduce energy consumption in cellular networks, the effective and common method is to shut down idle base stations...
Simulations of electromagnetic field and the resulting Lorentz force of Electromagnetic Acoustic Transducers (EMAT) for evaluation of non-magnetic conductors are normally realized via Finite Element Modeling (FEM) which is subject to considerably high computation burden due to a large amount of meshes within the solution region. In light of this, this paper proposes an analytical model of EMAT for...
In recent years, with the development of technology, the potential and application value of GIS (Geography Information System) has been shown in various fields. GIS performs well in data processing and graphic display but still has some shortcomings in some high-abstract-level areas like model library. In this paper we presented a model library by XML (Extensible Markup Language), and described its...
Techniques of Search Engine Optimization (SEO) are observed from four aspects: structure optimization, keywords optimization, content optimization, and link optimization. This paper seeks to analyze the impact of SEO techniques on the effectiveness of SEO, to figure out which technique strategy is most effective, and furthermore, to test the possible influence of SEO techniques on Page Interest. Different...
By using the regional climate model RegCM3 this paper simulated the drought over Southwest China during 2009 and 2010. By using to the NCEP reanalysis data this paper analyzed the impact of the atmospheric precipitable water, the water vapor transport and the water vapor budget. The result showed that: atmospheric precipitable water was less about 20% than normal years during the drought. The meridional...
A new method integrating reduced model and mixed design variables is proposed and applied in the lightweight design of a bus skeleton for the purpose of mass reduction without loss in structural performance. A whole skeleton model and a reduced model are built. All parts except chassis and floor assembly are reduced out using static reduction method. Reduced model is verified with finite element analysis...
This paper introduced the process algebra based language and its model-checking tools for trusted software architectural modeling, which deals with incompatibility between two components due to a single interaction or the combination of several interactions and with the lack of interoperability among a set of components through architectural compatibility check and interoperability check relying on...
Modern network computing is in the process of changing from manual management to autonomic computing. As the core of network computing, database management system with autonomic computing must be able to participate in the process to meet the performance requirements of the network applications. This paper studies on workload adaptation technology. In the workload adaptation framework, the performance...
Assume no population ingoing and outmigration after the infection outbreak in an region, a kind of two instantaneous and two absorption states Markov model with multi-causes death competition was presented. It can describe the epidemic transfer strength, direct mortality and indirect mortality, and obtain their expectation respectively.
