--First, it was pointed out in this paper that there exists a hierarchical organization of entity to be represented by the neural networks. This hierarchical organization leads to four levels of correspondences between the entity, patterns, elements, items and the units. Then we classified representations further into more detailed categories from two(More)
---It was pointed out in this paper that the planar topology of current backpropagation neural network (BPNN) sets limits to solve the slow convergence rate problem, local minima, incapability of learning etc. problems associated with BPNN. The parallel probabilistic neural network (PPNN) using a new neural network topology---stereotopology----was proposed(More)
The photocatalytic oxidation of the organic pollutants with TiO(2) as photocatalyst has been widely studied in the world, and many achievements have been made. The degradation of pollutants is highly related to the photocatalytic activity of TiO(2). It is demonstrated that doping ions to TiO(2) is one way to enhance the photocatalytic activity of TiO(2). In(More)
Organophosphate esters, widely used as flame retardants and plasticizers, are regarded as a class of emerging pollutants. In this work, a novel approach was developed for the fabrication of a solid-phase microextraction fiber by using hybrid silica-based materials with immobilized ionic liquids with sol-gel technology, and the prepared solid-phase(More)
