Public safety has been discussed for many years, but how to use and understand crime data is still difficult. Limitations of previous research were mainly restricted by technology. The significant technological advance since last century provided a tool for researchers to compute large amount of data and complicate models while shrinking process time too. This research tried to combine results from...
Agricultural drought greatly impacts the crop yield. Monitoring agricultural drought can deliver critical information to farmers on when, where and how much to irrigate. However, precisely monitoring which requires many kinds of data sources and data fusion and mining is still a huge challenge for scientists. In recent years, many data sources like remote sensed hyperspectral images are released online...
This paper investigates the problem of generalized direction detection in unknown Gaussian noise in sample-starved environment where the training data are insufficient such that the original sample covariance matrix is singular. To devise effective detectors, we first perform a unitary matrix transformation to the test data, which results in a signal-free data set, denoted as the virtual training...
Compressed sensing (CS) is the theory and practice of sub-Nyquist sampling of sparse signals of interest. Perfect reconstruction may then be possible with much fewer than the Nyquist required number of data. In this paper, we consider a distributed multi-view imaging system where each camera at a different location performs independent compressed sensing acquisition of the target scene. At the decoder,...
17 tomato cultivars inoculated with larva nematodes were used in this paper to investigate their resistance to root knot nenatodes. The results showed that gall index of LA1312, 3601, HA4402, LA1007 were higher than other tomato cultivars. Compared with control ‘Caihong101’, root activity of LA0655 was higher, and the lowest root activity was observed in 3601, whose gall index was the highest among...
A water environment security assessing system is constructed to respect the water environment security situation on pollution source, water quality, and ecology along Luan River to Tianjin Diversion Project. The model for assessment is proposed based on multi-hierarchy fuzzy theory. The corresponding assessment indexes, quantitative standards and weight functions are established. The system and method...
Corporate social responsibility is an important value orientation of economic and social development. As financial services intermediaries, the commercial banks for a country's economic health are particularly important. Actively fulfilling their social responsibilities is also an effective way to enhance the competitiveness of banks. In-depth study on the disclosure status and impact factors of commercial...
In view of the adverse effects of declining cluster, a method of evaluating risk level of mature cluster is developed. Through analyzing causes of declining, a risk indexes system is established. The features of clusterpsilas operation conditions with different risk levels are described. Owing to the complexity and uncertainty of cluster system, a TOPSIS comprehensive evaluation method based on fuzzy...
