  • In this paper, we explore the possibility to use wavelet decomposition based on modified octave structured 5-level filter banks as a set of features for speech recognition. The HMM (Hidden Markov Model) is used as a recognizer 〔l〕. We compared the performance of the wavelet decomposition with the mel-cepstrum and LPC cepstrum. Experimental results show favorable results.

  • New methods for storing and retrieving semi-structured data such XML documents has been recently studied. In this paper, we concern querying of XML data stored in relational tables. We first describe a method of querying XML documents using Oracle XDK, especially XSQL Servlet. We then apply the method to XML documents describing book information.

This paper explores two areas...cost of capital and inflation...with the intention of providing insight for a more structured and economic based approach to contractor equipment replacement practices rather than by the traditional "rule of thumb".umb".uot;.
