The occurrence and fate of organotins compounds in drinking water plant in Chongqing of southern China was investigated for the first time. Water samples were extracted by solid phase micro-extraction (SPME) and measured by gas chromatograph (GC) with mass spectrum (MS). Results showed the presence of organotin pollution in drinking water plant in Chongqing and most of organotins was MBT with the...
SPIHT and NLS (Not List SPIHT) are efficient compression algorithms, but the algorithms application is limited by the shortcomings of the poor error resistance and slow compression speed in the aviation and other areas requiring high-speed compression. In this paper, the error resilience and the compression speed are improved. The remote sensing images are decomposed by Le Gall5/3 wavelet, and wavelet...
Transfer hub platform gather much people in one small place. when emergency event happen, Transfer hub platform well become the very dangerous palace. So building a suited passenger evacuation model in Transfer hub platform to simulation crowd and group evacuation in the emergency situation is very importation. The goal of the paper is create a framework of passenger evacuation concept model to help...
The antioxidant content and activity, and antiproliferation activity of jujube fruit that were harvested at different harvest maturity and stored at 0 and 15°C for 15 d were studied. As fruit matured, except triterpenoid saponins, total phenolic and flavonoid concentrations of jujube were affected by harvest maturity, storage temperature and storage time very much. These antioxitant contents in fruit...
The spatial relations representation modeling is a basic task of computer graphics comprehension, however, previous modeling is usually aimed at a certain kind of relations such as direction, topology and distance. The models are relatively independent and inconsistent with human's cognitive logic, thus building a unified spatial relations representation modeling based on different reference frames...
A non-linear image enhancement algorithm called Adaptive Color Restoration and Luminance MSR Based Scheme for Image Enhancement (ACRL_MSR) is presented in this paper to improve the visual quality of color images under poor lighting condition. The Red, Green, Blue(R, G, B) color bands are enhanced by adjusting luminance which is automatically enhanced to a proper range based on Human Visual System...
