The energy efficiency level of wind turbines reflected its operation efficiency and provides evidence for the diagnosis. Currently, the evaluation study is concerned essentially with a part of Wind Turbine, but that has limitations. This paper establishes a synthetic evaluation index system of the energy efficiency evaluation of Wind Turbine from five respects, which include Comprehensive, profitability,...
The Vulnerability Risk Assessment in general information network cannot exactly assess the vulnerabilities in Electric Power Information Network(EPIN). Aiming at the limitations of current vulnerability risk assessment technologies for general information network, a vulnerability risk assessment method for Electric Power Information Network is proposed on the basis of CVSS. A hierarchy assessment...
In this paper, an effective hyperspectral images compressed sensing algorithm based on hybrid spatial-spectral reconstruction is proposed. The iterative projected Landweber block compressed sensing algorithm based on improved noise variance estimation is used for the intraband reconstruction and the spectral prediction residual reconstruction is adopted for interband reconstruction. Furthermore, the...
3D facial landmarks play a significant role in many 3D facial studies. Due to the complex geometry of high resolution 3D human face, landmark detection remains to be a challenge problem. This paper proposes a novel method to detect landmarks automatically for high resolution 3D faces without learning or training, solely using geometric information. For high resolution 3D faces, geodesic remeshing...
In a monopolistic cable television (CATV) service market, it is generally believed that tiered charging is beneficial to consumer surplus as compared to flat rate charging while it is likely to reduce supplier income. Can the addition of a carefully designed Price-Channel-Downscaled (PCD) package to a flat rate (FR) package stimulate enough new subscribers and achieve Pareto improvement between cable...
Objective: This study aims to investigate the effect of Chinese herbs treatment of Kidney-strengthening therapy, Spleen-invigorating therapy and Liver-regulating therapy on monoamine neurotransmitters in ovariectomized female rats. Methods: 54 female rats were divided into six groups by random: control group, sham operation group, model group, Spleen-invigorating group, Kidney-strengthening group...
Data deduplication techniques improve cost efficiency by dramatically reducing space needs of storage systems. SSD-based data cache has been adopted to remedy the declining I/O performance induced by deduplication operations in the latency-sensitive primary storage. Unfortunately, frequent data updates caused by classical cache algorithms (e.g., FIFO, LRU, and LFU) inevitably slow down SSDs' I/O processing...
With the purpose of doing quantification of individual tacit knowledge, this paper discusses different classifications of the recessive knowledge from all aspects and does further research of the secondary index subordinating to every index in order to design a psychological scale including questions corresponding to different indexes, with which the individual tacit knowledge was successfully quantified.
This paper proposes a novel and practical method to design the parameters of LC filter in distribution STATCOM. The filter parameters are mainly determined by four factors: the resonant frequency, the harmonic distortion rate, inductance fundamental voltage drop, and the reactive power compensation ability. The proposed method in this paper is that selecting larger filter inductance and capacitance...
The next generation digital video broadcasting network of China will aim at connections of regional metropolises, which introduces problems of content protection among operators. So it is crucial to solve the problem of stream media services for encrypted programs. This paper proposes a time-shifted TV scheme for encrypted DVB programs, in which linear adaptive prediction model is adopted. Suitable...
Caching can improve the browser's efficiency, this paper proposes one distributed sharing model of the browser cache: each end-host's address and the Web site URL address are mapped to the identical key space, the storing information of the shared cache mapped to key k is saved on the same key k mapped end-host; it also presents a distributed lookup protocol with a constant O(1) hop per lookup request,...
The question of finding the community structure of a complex network has been addressed in many different ways. Here we utilize a clustering method called affinity propagation, associating with some existent measures on graphs, such as the shortest path, the diffusion distance and the dissimilarity index, to solve the network partitioning problem. This method considers all nodes as potential exemplars,...
Mobile informational strategy has a higher demand on the network supporting system and aims at the implementation of user oriented service management. As the indexes of customer perception are the direct reflection of the network quality, it is particularly important to analyze the indexes. In this paper, varieties of factors affecting customer experiences on the network quality are analyzed. A customer...
Distribution centers site selection has become a popular problem in recent years. Fine distribution centers site selection can ensure the supply and reduce the cost. By studying the methods proposed by other scholars, a mew method, KPCA (kernel principal component analysis) -SVRM (support vector regression machine) is proposed by this paper. The first step of this method is to apply KPCA to SVRM for...
