METHODS. A semiquantitative assessment of total HPC over 1 week, 1 month, and 6 months was obtained by using information gathered from a questionnaire. Moderate to high HPC consumption was defined as $10 g/wk. To quantify ambient household peanut levels, dust samples from all household members’ beds, the infant’s crib, and the infant’s play area were obtained by vacuuming. Wipe samples were obt...

With the increase of digital technology in video production, several types of complex video special efsects editing have begun to appear in video clips. In this paper, a novel algorithm is proposed for fade-in, fade-out, dissolve and wipe video editing operations in MPEG-2 [ I ] compressed domain without fu l l frame decompression and motion reestimation. Results show that both objective and su...

Arsenic contamination on the surface of buildings and facilities at a coking plant and associated health risk were studied. A total of 94 wipe samples from 56 buildings and facilities were collected, and As concentrations were found to range from 0.01 to 23.90 μg/100 cm(2). 20.2% of the samples exceeded the As level calculated to present health risk: 4.02 μg/100 cm(2). Arsenic mean concentratio...

Web spider is a widely used approach to obtain information for search engines. As the size of the Web grows, it becomes a natural choice to parallelize the spider’s crawling process. This paper presents a parallel web spider model based on multi-agent system for cooperative information gathering. It uses the dynamic assignment mechanism to wipe off redundant web pages caused by parallelization....
