In this paper, we firstly recall some recent contributions of pipe routing design which are categorized into four fields: factory layout, circuit layout, aircraft design and ship piping system design. The main constrains in this filed are then discussed. Lastly, a brief overview of the major design approaches is provided.
Product modeling and data exchange has been recognized as one of the sky issues of implementing a product overall lifecycle management (PLM) system. In this paper, a product integrated models during the whole phases of lifecycle is proposed first. Based on the integrated models, a multidisciplinary collaborative design method over Internet is discussed.(More)

We describe a case of extensive calcifications in the portal venous system in a middle-aged male patient with hepatocellular carcinoma (HCC). This patient presented with epigastric pain that had no obvious origin prior to(More)
Development of agricultural biotechnology requires rapid and convenient methods for crop plant genotyping. Real-time PCR is sensitive and reliable, and has been a routine technique in plant research. However, its application is limited by the cumbersome DNA template preparation procedures. We tested three PCR master mixes for direct amplification of crude(More)
