  1. 16. In the long run, we're all mean reverting - Wavelet analysis on the fate of real exchange rates

    Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :David Berger; [2013]
    Nyckelord :Purchasing Power Parity; Long Run Memory; ARFIMA p; d; q ; Unit root tests; Wavelets; Business and Economics;

    Sammanfattning : This paper analyzes to what extent PPP holds in the long run. Firstly, standard unit root tests are used to test for stationarity. These results are then compared to the ones provided by a wavelet based OLS and an approximate ML estimator. LÄS MER

  3. 17. System Surveillance

    Master-uppsats, Statistik; Tekniska högskolan

    Författare :Shaheer Mansoor; [2013]
    Nyckelord :State Space Models; Forecasting; Wavelets; LOESS; Change Point Detection; Financial Systems; Trading; Transactions per second; Kalman Filtering;

    Sammanfattning : In recent years, trade activity in stock markets has increased substantially. This is mainly attributed to the development of powerful computers and intranets connecting traders to markets across the globe. LÄS MER

  4. 18. EEG enhancement for EEG source localization in brain-machine speller

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Parinaz Babaeeghazvini; [2013]
    Nyckelord :Brain-Computer interface BCI ; Brain-machine speller; Electroencephalogram EEG ; source localization; source reconstruction;

    Sammanfattning : A Brain-Computer Interface (BCI) is a system to communicate with external world through the brain activity. The brain activity is measured by Electro-Encephalography (EEG) and then processed by a BCI system. EEG source reconstruction could be a way to improve the accuracy of EEG classification in EEGbased brain–computer interface (BCI). LÄS MER

  5. 19. Evaluation of performance of a smartphone application for measuring bike paths’ condition

    Master-uppsats, Institutionen för datavetenskap; Tekniska högskolan

    Författare :Jonas Erlandsson; [2013]
    Nyckelord :Statistics; smartphone application; bike path; RMS; Gaussian process; Wavelets; Statistik; smartphoneapplikation; cykelvägar; RMS; Gaussian process; Wavelets;

    Sammanfattning : There are several methods to measure surface evenness for car roads, but almost none for bike paths. Accordingly, VTI (the Swedish National Road and Transport Research Institute) have created a smartphone application which uses the accelerometers in the phone to measure the vibration from the road.

  7. 20. Super Resolution Image Reconstruction using LWT

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Sivakrishna Padavala; Arifullah Baig Moghul; [2013]
    Nyckelord :Wavelets; Lifting Scheme; Super Resolution; Daubechies; Image Registration; SPIHT;

    Sammanfattning : Since over three decades, computers have been widely used for processing and displaying images. The ability to process visual information from a super resolution image can enhance the information present in the image. LÄS MER
