Accurate network traffic classification is crucial for network management and has received widespread attention in the last few years. However, there is not a reliable and widely accepted validation technique for verifying these classification approaches. The main reason is that there are not public traffic traces with accurate application information. In order to address the above problem, this paper...
Shot segmentation is one of the most important steps for video analysis and retrieval. An effective shot segmentation algorithm is proposed by using DC-reduced graph which is on the basis of DC coefficients in I-Frames. This algorithm constructs the sequence of DC-reduced graph by DC coefficients in I-Frame firstly, and then the difference between two adjacent DC-reduced graphs is measured using color...
In order to confirm the optimum plants combination and conditions, pot experiment was conducted to study phytoremediation efficiency of maize, ryegrass and alfalfa for heavy metal-organic contaminated sewage river sediment. Three different treatment levels were designed, and dehydrogenase activity change in sediment was inspected. Results showed that the best plants combination of repair and best...
Pot experiment was conducted to study phytoremediation efficiency of maize, ryegrass, Indian mustard and Medico go sativa L for heavy metal-organic contaminated sewage river sediment. Three different treatment levels were designed, and urease activity change in sediment was inspected. Results showed that the method of EDTA-induced phytoremediation can promote the absorption of heavy metal by plant...
According to the application of secondary water-supply system has been used more and more, the problem of water pollution in secondary water-supply system turns serious. Research was made on distributing rules of bacteria in secondary water-supply system; the variety and correlativity of water quality index were analyzed. Index that reflecting total bacteria number in water-supply system was indicated;...
According to Environmental Quality Standards for Surface Water in China (GB3838-2002), we used the 2006-2007 monitoring data to evaluate and characterize the water quality condition of a landscape river in Tianjin based on the comprehensive index methods such as Nemerow Index and single-factor assessment. The results are obtained as follows: (1) The water quality of M River belongs to class V water...
According to Environmental Quality Standards for Surface Water in China (GB3838-2002), monitoring data were used to evaluate and characterize the water quality condition of a landscape river in Tianjin based on the comprehensive index methods such as Nemerow Index and single-factor assessment. The results showed that the water quality of J River belongs to class V water body; the main pollutants of...
