  1. 1. Passive Radar Detection of Aerial Targets

    M1-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Andreas Örstadius; Erol Ali; [2017]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The purpose of this thesis is to construct a passive bistatic radar system using two USRP N200 software defined radios and two ordinary TV-antennas. Several auxiliary components were used in order to align and calibrate the devices including an octoclock CDA-2990, switch and signal generator. LÄS MER

    Sammanfattning : Many studies have been conducted investigating automatically activated attitudes towards ethnic groups, where the main measure has been reaction time. Mainly, these studies have looked at relative preferences for ethnic in-groups over ethnic out-groups. LÄS MER

  3. 3. Localization of Brain Activity in Electroencephalography Data during Brain-Computer Interface Operation

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Oskar Hjärtquist; [2011]
    Nyckelord :P300 ; N200; Event-related potential ERP; Noise Subspace Fitting NSF ; Null Space Projection NP ; Localization; Dipole source; Elec- troencephalography EEG ; Brain-Computer Interface BCI Speller; Technology and Engineering;

    Sammanfattning : In this Master's thesis I present a means of finding active sources of cortical electrical activity from electroencephalogram (EEG) data acquired during operation of a brain-computer interface (BCI). A novel subspace-based technique was used to suppress spatially correlated EEG interference sources, followed by a technique that estimates the source parameters with a near maximum likelihood performance.
