The traditional manual counting wafers leaded to the silicon wafer cracked by operating frequently. Instead of the manual work, this paper proposed a system to counting wafers based on Machine Vision theory and Image Processing algorithm. We designed a counter system and adopted infrared led as parallel illumination source. In image pre-processing, this(More)
Modern research would be unthinkable without interdisciplinary approaches. For example, many of the biological disciplines provide proof by their names: biochemistry and biological chemistry, biophysics, biotechnology, biomaterials, biostatistics, bioinformatics, and computational biology, all encompass aspects of biology that are influenced by at least one(More)
A standardized data model is proposed for the solution of data sharing between geographic information systems (GIS) and microscopic traffic simulation systems. The object oriented technology, layer and package expression are used to abstract the characteristics of the proposed model, which then is described with the UML technique. The definition of entity(More)
