In the speech processing system, detection of a single speech from composite signals is required. To obtain the single speech, we propose an algorithm which can detect multi-pitch in the frame processing. The algorithm does not require the condition that the overlapped peaks should be analyzed into each speaker’s peaks. The proposed algorithm produces pitch candidates for each speech such that ...

2 Introduction Resolution is one of the principal aims of all chromatographic techniques. Therefore, a major goal of chromatographic method development is to obtain an adequate separation of all components of interest in a reasonable time. However, in spite of ongoing instrumentation improvements, peaks are often poorly resolved and measurements must be made using deconvolution programs. In som...

in this paper, absorption spectra of both solution and films of cyano azobenzene polymer are investigated. the analysis of overlapped absorption spectra of polymer, related to trans and cis isomers, shows that the population of cis isomers is higher than trans isomers. it means that, cyano azobenzene molecules have a folded structure in polymer, in thermal equilibrium. presence of cyano molecul...

We present the software Peak INTegration (PINT), designed to perform integration of peaks in NMR spectra. The program is very simple to run, yet powerful enough to handle complicated spectra. Peaks are integrated by fitting predefined line shapes to experimental data and the fitting can be customized to deal with, for instance, heavily overlapped peaks. The results can be inspected visually, wh...

In this work, we have studied the influence of dc joule-heating thermal processing on the structure, magnetoimpedance (MI) and thermal properties of Co64Fe4Ni2B19-xSi8Cr3Alx (x = 0, 1, and 2) rapidly solidified melt-spun ribbons. The nanocrystallization process was carried out by the current annealing of as-spun samples at various current densities. As-spun and joule-heated samples were studied...

Information on metal binding with fluorescent substances has been widely studied. By contrast, information on metal binding with non-fluorescent substances remains lacking despite the dominance of these substances in aquatic systems. In this study, the metal binding properties of both fluorescent and non-fluorescent substances were investigated by using metal titration combined with two-dimensi...

Depth and wavelength dependence of absorption and scattering coefficients at the South Pole AMANDA site were mapped with pulsed and D.C. light sources. The contribution of air bubbles to scattering decreases with depth and disappears at 1.4 km; at greater depths scattering by dust dominates. Peaks in scattering at several well-defined depths are attributed to peaks in dust concentration and are...
