For digital libraries it is very important to design and to implement powerful engines to convert information on paper to electronic format. In this paper a PageX software is proposed as the integration of such engines, which include a set of intelligent document processing functions, a set of compact document management strategies, and a set of advanced(More)
In this paper a new hierarchical distributed genetic algorithm is proposed for image segmentation. Firstly, a technique of histogram dichotomy is proposed to explore the statistical property of input image and produce a hierarchical quantization image. Then a Hierarchical distributed genetic algorithm (HDGA) is imposed on the quantized image to explore the(More)
Recent work on Clark-type pO2 electrodes has shown that significant performance improvements can be achieved through the use of a multicathode arrangement. To provide a sound basis for the design of such electrodes, we present an analysis and discussion of their properties. The electrode is initially modelled by asuming the cathodes consist of(More)
