  1. 1. On Speech-to-Text Alignment, Phonetic Labeling, and Recursive Signal Processing

    Author : Åke Andersson; Chalmers University of Technology; []
    Keywords : phonetic labeling; recursive algorithms; adaptive algorithms; speech-to-text alignment; dynamic programming; time-varying systems; subspace tracking; time-alignment; parameter estimation; time-warping;

    Abstract : Speech data-bases are an important issue in the study of speech communication. In particular, time-aligned and phonetically labeled speech data-bases are useful during the design of applications such as speech recognizers. The time-alignment and labeling of the speech data is traditionally done manually. READ MORE

  2. 2. Seismic tomography : Algorithms and applications

    Author : Zhengsheng Yao; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geophysics Specialized In Seismology; geofysik; med inriktning mot seismologi;

    Abstract : A preferred algorithm for seismic tomography needs to have capabilities including computational efficiency, minimal computer memory requirements, easy regularization and nonuniqueness analysis. In this thesis, regularised recursive least squares for seismic tomography is developed. READ MORE

  5. 5. Distributed k-ary System: Algorithms for Distributed Hash Tables

    Author : Ali Ghodsi; Seif Haridi; Alexander Reinefeld; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; distributed hash tables; structured overlay networks; distributed algorithms; distributed systems; group communication; replication; Computer science; Datavetenskap;

    Abstract : This dissertation presents algorithms for data structures called distributed hash tables (DHT) or structured overlay networks, which are used to build scalable self-managing distributed systems. The provided algorithms guarantee lookup consistency in the presence of dynamism: they guarantee consistent lookup results in the presence of nodes joining and leaving. READ MORE
