Automatic placement and routing technology for interactive 3D application

Automatic placement and routing technology provides an effective tool for designing simulation and information guidance.Various intelligent algorithms in mechanical design,ocean and ship engineering and aerospace design have been implemented.However,automatic placement and routing has never been integrated into interactive 3D application.In this paper,idea of combining the interactive 3D application with automatic placement and routing is proposed,and its main issue is discussed.Then we present a new placement and routing algorithm suitable for 3D interactive application containing model design,fundamental algorithm and global optimization to remove routing blockage.Experimental results demonstrate that the proposed algorithm works effectively in simulation,meets the requirements of real-time rendering and has great practical value.     

Vector sampling theorem for wavelet subspaces

The vector sampling theorem has been investigated and widely used by multi-channel deconvolution, multi-source separation and multi-input multi-output （MIh40） systems. Commonly, for most of the results on MIMO systems, the input signals are supposed to be band-limited. In this paper, we study the vector sampling theorem for the wavelet subspaces with reproducing kernel. The case of uniform sampling is discussed, and the necessary and sufficient conditions for reconstruction are given. Examples axe also presented.     

耳蜗模型在正弦表示的语音分析/合成中的应用

A sinusoidal representation of speech and a cochlear model are used to extract speech parameters in this paper, and a speech analysis/synthesis system controlled by the auditory spectrum is developed with the model. The computer simulation shows that speech can be synthesized with only 12 parameters per frame on the average. The method has the advantages of few parameters, low complexity and high performance of speech representation. The synthetic speech has high intelligibility.
