    Sammanfattning : Over the last decade there has been an explosive growth in the use of wireless mobile communications. Second generations systems are mature technologies now and third generation systems and beyond are being implemented and researched. LÄS MER

  3. 2. Contributions of Satellite Geodesy to Post-Glacial Rebound Research

    Författare :Seyed Mehdi Shafiei Joud; Lars E. Sjöberg; Mohammad Bagherbandi; Martin Horwath; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glacial Isostatic Adjustment GIA ; gravimetric GIA modelling; satellite geodesy; Gravity Recovery And Climate Experiment GRACE ; independent component analysis ICA ; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : Glacial Isostatic Adjustment (GIA) is a global and long-term process in the Earth, which began 21.5 millennia ago, according to many ice history modellers. One way to understand the processes of the Earth’s interior, the crustal deformation, and a key correction to estimate the climatological parameters is obtained by studying GIA. LÄS MER

    Sammanfattning : The electronics industry is one of the most dynamic, fascinating and important industries. Polymeric adhesives are widely used in electronics packaging and play a critical role. LÄS MER

  5. 4. A tiny glimpse into the human brain using model-free analysis for resting-state fMRI data

    Författare :Yanlu Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Resting-state functional Magnetic Resonance Imaging (fMRI) acquires four dimensional data that indirectly depicts human brain activity. Within these four dimensional datasets reside resting-state functional connectivity networks (RFNs), depicting how the human brain is organized functionally. LÄS MER

  7. 5. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

    Författare :Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. LÄS MER
