Infrared videos from transmission line inspection of UAV have a large amount of data with low SNR (Signal to Noise Ratio). Identifying heat defects automatically using infrared videos is difficult and inefficient. In this paper, an advanced method is proposed. Firstly, points with excessive value of the component regions according to conductors are analyzed in their neighbors to obtain defect points...

Spectral clustering has become a popular subspace clustering algorithm in machine learning and data mining, which aims at finding a low-dimensional representation by utilizing the spectrum of a Laplacian matrix. It is a key to construct a discriminative and reliable affinity matrix for spectral clustering to achieve impressive clustering quality. As the real word data increase with higher dimension...
Ethylene diamine tetraacetic acid (EDTA) and sodium dodecyl sulfate (SDS) were employed to impregnate activated carbons for the purpose of lead removal. The mechanisms of surface impregnation and lead adsorption method of chemical regeneration were investigated. Results showed that the highest impregnation of EDTA and SDS on activated carbon was 0.33 and 0.96mmol/g, respectively. Adsorption capacities...
A wirelength-driven placer without considering routability could introduce irresolvable routing-congested placements. Therefore, it is desirable to develop an effective routability-driven placer for modern mixed-size designs employing hierarchical methodologies for faster turnaround time. This paper presents a novel two-stage technique to effectively identify design hierarchies and guide placement...
In wireless sensor networks, most of existing data aggregation scheduling methods try to aggregate the data from all the nodes at all time-instances. It is neither energy efficient nor practical because of the link unreliability and spatio-temporal data correlation. This paper proposes a lossy data aggregation scheme to allow estimated aggregation at the root by selectively letting some nodes sample...
A model was presented that safety performance of safety surveillance department in ATM should be evaluated by higher authorities, based on the effectiveness of carrying out safety and quality oversight. Four resultant indicators were ratio of identifying the errors, ratio of identifying the hazards, the defects of risk management and the insufficiency of safety supervision mechanism in operation departments...
