Abstract The acquisition of bathymetric data in shallower waters is difficult to attain using traditional survey methods because the areas investigate may not be accessible hydrographic vessels, due risk grounding. For this reason, use satellite detection depth (satellite-derived bathymetry, SDB) constitutes a particularly useful and also economically advantageous alternative. In fact, approach...

Recently, many techniques have been proposed to improve speaker identification in noise environments. Among these techniques, we consider the feature recombination technique for the multi-band approach in noise robust speaker identification. The conventional feature recombination technique is very effective in the band-limited noise condition, but in broad-band noise condition, the conventional...

In this paper we will present an approach to realize FIR filters using Chebyshev Polynomials. Chebyshev polynomials play a vital role in antenna as well as in signal processing theory. The FIR filter design has also been disscussed previously [2-10], these papers discuss approximation methods, while the approach we will discuss in this paper gives exact design of FIR filter in Chebyshev sense. ...

Multi-resolution sub-band cepstral features strive to exploit discriminative cues in localised regions of the spectral domain by supplementing the full bandwith cepstral features with subband cepstral features derived from several levels of sub-band decomposition. Mult-iresolution feature vectors, formed by concatenation of the subband cepstral features into an extended feature vector, are show...

In the dissertation, we study the statistical evaluation of treatment comparisons by evaluating the relative comparison of survival experiences between two treatment groups. We construct confidence interval and simultaneous confidence bands for the ratio and odds ratio of two survival functions through both parametric and nonparametric approaches. We first construct empirical likelihood confide...
