This paper aims to combine the practical application of artificial intelligence and modern navigation collision avoidance, to solve the difficult collision problem of ships which going through the complex water area. Based on AHP (The Analytic Hierarchy Process), ANN (Artificial Neural Network) and other methods, this paper proposes the T minutes prediction algorithm. In this algorithm, the parameter...
In this paper, a novel all phase DFT filter bank (APFB) for multi-carrier modulation is presented and the efficient implementation structure is derived. A narrowband APDFT prototype filter exhibits higher stop attenuation and an M-band APFB with the strict power complementarities can be easily achieved by designing the frequency response vectors. The impulse response of the proposed APFB is also real...
XML has become a standard for data description and exchange through Internet. There have appeared several methods to inquire about XML documents. In this paper, an optimized XQuery query scheme based on DTD is suggested. The scheme makes use of structure information in DTD corresponding to XML documents. In the scheme, the query pretreatment is carried out to obtain the possible path sets. In the...
