  3. 17. Automatic Sleep Scoring To Study Brain Resting State Networks During Sleep In Narcoleptic And Healthy Subjects : A Combination Of A Wavelet Filter Bank And An Artificial Neural Network

    Master-uppsats, Linköpings universitet/Institutionen för medicin och hälsa

    Författare :Federica Viola; [2014]
    Nyckelord :Automatic Sleep Scoring; Discrete Wavelet Transform; Filter Bank; Artificial Neural Network; Resting State Networks; Narcolepsy.;

    Sammanfattning : Manual sleep scoring, executed by visual inspection of the EEG, is a very time consuming activity, with an inherent subjective decisional component. Automatic sleep scoring could ease the job of the technicians, because faster and more accurate. LÄS MER

  4. 18. Implementation and Evaluation of Spectral Subtraction with Minimum Statistics using WOLA and FFT Modulated Filter Banks

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Peddi Srinivas Rao; Vallabhaneni Sreelatha; [2014]
    Nyckelord :Speech Enhancement; Filter Bank; Spectral Subtraction; Wiener Filtering; PESQ; DFT ; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Sammanfattning : In communication system environment speech signal is corrupted due to presence of additive acoustic noise, so with this distortion the effective communication is degraded in terms of the quality and intelligibility of speech. Now present research is going how effectively acoustic noise can be eliminated without affecting the original speech quality, this tends to be our challenging in this current research thesis work.

  5. 19. Replication, development and evaluation of a GDP indicator for the Swedish business cycle. Can the framework of ECB’s indicator ALI be used to create an indicator for the Swedish business cycle?

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Elina Svensson; [2014]
    Nyckelord :leading indicator; index; Principal Component Analysis; data-driven; turning point; filter; bias; efficiency; accuracy; Business and Economics;

    Sammanfattning : This study shows that the framework used to construct the successful Euro Area Leading Indicator (ALI), developed by de Bondt and Hahn on behalf of the European Central Bank, can successfully be applied to the Swedish business cycle. The ALI type indicator constructed in this study is a weighted index of nine macroeconomic series and accurately predicts the Swedish business cycle by three months (or longer). LÄS MER

  7. 20. Geolocation by Light using Target Tracking

    Master-uppsats, Reglerteknik; Tekniska högskolan

    Författare :Linus Envall; [2013]
    Nyckelord :target tracking; EKF; solar elevation angle; light intensity; geolocation; smoothing; filter bank; IMM;

    Sammanfattning : In order to understand the migration patterns of migrating birds, it is necessary to understand whenand where to they migrate. Many of these birds are very small and thus cannot carry heavy sensors;hence it is necessary to be able to perform positioning using a very small sensor. One way to do this isto use a light-intensity sensor. LÄS MER
