Abstract: A method for adaptively determining statistical model for voice activity detection is provided to model DFT(Discrete Fourier Transform) coefficients of clean speech and noise by adaptively determining proper statistical models according to noise types and SNR(Signal-to-Noise Ratio) conditions instead of Gaussian models. In a method for adaptively determining statistical model for voice activity detection, KS(Kolomogorov-Sriminov) test statistic Tt(Xm) is obtained for Xm={X(t),X(t-1),...,X(t-m)} by using a formula 1, which includes DFT coefficients for sound mixed with noise in m previous frames when X(t) is assumed as the DFT coefficients for the sound in frame t. The formula 1 is equation 1. Fx(Xi) is an empirical accumulation distribution function defined by formula 2, and an empirical accumulation distribution function for a predetermined statistical model. An equation 2, X(n),n=1,...,N is order statistics of data X from a minimum element X(1) to a maximum element X(N) of X. An evaluation value for the KS test statistical Tt(Xm) is obtained by formula 3. An equation 3, wherein lambdaT is a smoothing parameter. Such evaluation values obtained for each statistical model are compared to select a minimum one as an optimum one. The above steps are repeated per frame of a predetermined section, so that an optimum statistical model for the frames of the section is adaptively obtained.

Title: Metallization of substrate(s) by a liquid/vapor deposition process
Inventor: DEAVENPORT DENNIS LEON
IPC: C23C16/18
Filed: 2004-09-16
Abstract: A process for depositing a substantially pure, conformal metal layer on one or more substrates through the decomposition of a metal-containing precursor. During this deposition process, the substrate(s) is maintained at a temperature greater than the decomposition temperature of the precursor while the surrounding atmosphere is maintained at a temperature lower than the decomposition temperature of the precursor. The precursor is dispersed within a transport medium, e.g., a vapor phase. The concentration of the metal- containing precursor(s) in the vapor phase, which also contains liquid therein, can be at a level to provide conditions at or near saturation for the metal precursor(s). In ensuring the aforementioned temperature control between the transport media and substrate, and in maintaining saturation conditions for the transport media, the quality of the deposited metal thin film is markedly improved and the production of by- product metal dust is greatly reduced or substantially eliminated.
