acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. the analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. the changes in long-term average spectrum (ltas) spectral ...

The energies of the emission spectral lines originating from vacancies in deep atomic shells change if the elements are in different oxidation states. These changes of energies cause small shifts in spectral lines. For Sulfur and Magnesium, these shifts are shown in this work, and also the influence that they may have on the calibration of wavelength-dispersive spectrometers and in consequence,...

in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...

Introduction Raman spectroscopy is a vibrational spectroscopic technique, based on inelastic scattering of monochromatic light. This technique can provide valuable information about biomolecular changes, associated with neoplastic transformation. The purpose of this study was to find Raman spectral markers for distinguishing normal samples from cancerous ones in different tissues. Materials and...

Introduction: Purkinje Cell (PC) output displays a complex firing pattern consisting of high frequency sodium spikes and low frequency calcium spikes, and disruption in this firing behavior may contribute to cerebellar ataxia. Riluzole, neuroprotective agent, has been demonstrated to have neuroprotective effects in cerebellar ataxia. Here, the spectral analysis of PCs firing in control, 3-acety...

There is no evidence that previous studies, available to Iran’s inflation literature, have used spectral methodology to analyze a possible relationship between inflation and its main determinants within a specific period. Accordingly, the present study investigates the effects of money growth, real output growth, output gap and interest rate changes on inflation at low and high frequencies...
