  1. 1. Discrete Stochastic Time-Frequency Analysis and Cepstrum Estimation

    Detta är en avhandling från Lund University

    Författare :Johan Sandberg; Lunds universitet.; Lund University.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; time-frequency analysis; ambiguity domain; time-frequency representations; covariance function; non-stationary random processes; Speaker recognition; MFCC; cepstrum;

    Sammanfattning : The theory of stochastic time-frequency analysis of non-stationary random processes has mostly been developed for processes in continuous time. In practice however, random processes are observed, processed, and interpreted at a finite set of time points. LÄS MER

  2. 2. Electroglottographic analysis of phonatory dynamics and states

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Andreas Selamtzis; KTH.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; voice function; phonation; vocal fold vibration; vocal registers; electroglottography;

    Sammanfattning : The human voice is a product of an intricate biophysical system. The complexity of this system enables a rich variety of possible sounds, but at the same time poses great challenges for quantitative voice analysis. For example, the vocal folds can vibrate in several different ways, leading to variations in the acoustic output. LÄS MER

  3. 3. Electromagnetic Dispersion Modeling and Analysis for Power Cables

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Stefan Gustafsson; Linnéuniversitetet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; power cable; electromagnetic model; dispersion relation; asymptotic analysis; sensitivity analysis;

    Sammanfattning : This thesis addresses electromagnetic wave propagation in power cables. It consists of five papers, where the three first papers are based on one and the same model, and the last two papers are based on a similar but slightly different model. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electric fields; Surface design; Chemical analysis; Bipolar electrodes; Impedance spectroscopy; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Electrochemistry; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Elektrokemi; NATURAL SCIENCES Chemistry Physical chemistry Chemical physics; NATURVETENSKAP Kemi Fysikalisk kemi Kemisk fysik; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; NATURAL SCIENCES Chemistry Physical chemistry Surface and colloid chemistry; NATURVETENSKAP Kemi Fysikalisk kemi Yt- och kolloidkemi;

    Sammanfattning : This thesis deals with the use of electric fields for evaluation and control of chemical systems. An electric field can result in the flow of charge across an interface between a metal and a solution, by means of chemical reactions. This interplay between electricity and chemistry, i.e. LÄS MER
