It is an important measure for China to implement the strategy of major functional area (MFA) to promote the optimization and upgrading of the industry and the development of regional integration. In order to study spatial correlation structure between optimization development zone and key development zone, the paper chooses Beijing-Tianjin-Hebei Metropolitan Region (BTHMR) and Ha-Chang City Group...
Recent real-world sensor network deployments have helped decision makers and sensor data analysts draw highly precise conclusions by relying on finer-grained raw sensory data. A small number of anomalous sensor readings, however, lead to misinterpretations and false conclusions. Hence, detecting and eliminating anomalies in sensor network deployments play a major role during the decision making process...
Topic relevance of pages and hyperlinks is the key issue in focused crawling. In this paper, an improved topic relevance algorithm for focused crawling is proposed. First, we implement a prototype system of the focused crawler - a topic-specific news gathering system which is prepared for comparative experiments on different similarity measures with the anchor text. Second, experiments on Chinese...
Existing approaches for automatic image annotation usually suffer from two issues: (1) lacking a good quality distance metric for image semantic similarity measure; (2) rarely considering the correlation between labels assigned to each image. In this paper, we aim to resolve both of the problems simultaneously in a novel unified framework. Specifically, a proper distance metric is learned based on...
With the rapid development of China's economy, China is now the largest iron ore consumer in the world. However, due to the particularity of its pricing mechanism, the import price for iron ore in China has been rising in recent years, which leads to a continuous decline in the profits of the iron and steel industry. This paper analyses how international crude oil price and Baltic Dry Index impact...
Near infrared spectroscopy (NIRS) combined with partial least squares (PLS) was applied to establish model for quantitative analysis of the Polysaccharide in Irpex lacteus Fr. mycelia. Savitzky-Golay smoothing, First derivative, second derivative, fast Fourier transform (FFT) and standard normal variate (SNV) transformation methods were applied to preprocess NIRS. The efficacious spectral regions...
Localized defects in rotary machinery parts tend to result in impulse response in vibration signal, whose parameters provide a potential approach for localized fault diagnosis. A method combining the Morlet wavelet and Correlation Filtering, named Cyclic Morlet Wavelet Correlation Filtering (CMWCF), is proposed for identifying both the impulse response parameters and the cyclic period. Simulation...
Now medical imaging processing technology is a very hot subject. The digital image processing in spectral imaging technology field is one of the incarnations. The article is base on the experiment of fresh samples of bone cancer in adults. By using spectral similarity mapping and correlation algorithm, we get two different images. The result of correlation algorithm is fast, but unclear, while the...
This paper proposed a new bit-allocation algorithm based on linear prediction for AAC (advanced audio coding) audio encoder. Initial value of bit-allocation information of current audio frame is calculated by linear prediction algorithm using the information of previous two audio frames. Because the number of iteration for bit-allocation module is high correlated with initial value of bit-allocation...
Based on extensive literature review and qualitative research, we propose the multidimensional and hierarchical model to measure the quality of mobile securities service. In the empirical study, the sample which contains 217 valid respondents is selected from China Mobile and China Unicom. Through three stages validating, all three levels of proposed hierarchical structure are very strongly supported...
