  1. 1. Optimising a small satellite for hard X-ray polarisation studies of gamma ray Bursts.

    Kandidat-uppsats, KTH/Fysik

    Författare :Erik Ahlberg; Samin Hasan; [2014]
    Nyckelord :;

    Sammanfattning : Gamma ray bursts (GRBs) originate from extremely energetic extra-galactic events, and much is still unknown about them. Whereas the energy and time structure of GRBs have been studied extensively the past years, only a few polarisation measurements have been made on their initial, prompt emission. LÄS MER

  3. 2. Directional Spectrum Sensing and Transmission Using a Sector Antenna

    Master-uppsats, Institutionen för informationsteknologi och medier

    Författare :Bilal Hasan Qureshi; [2012]
    Nyckelord :Spectrum Sensing; Ray-tracing and Sector Antennas;

    Sammanfattning : Spectrum sensing plays a key role for radio resource awareness in cognitive radio. To enhance the capabilities of cognitive radio nodes, exploiting the spatial resource in addition to frequency and time re-sources seems reasonable. LÄS MER

  4. 3. Apoptosis in mouse J774 macrophages : a methodological study

    Master-uppsats, Institutionen för klinisk och experimentell medicin; Hälsouniversitetet

    Författare :Hasan Imam; [2009]
    Nyckelord :;

    Sammanfattning : The approach of studying apoptosis induced by UV ray and actinomycin treatment was done to find a suitable positive control for that apoptosis study, with murine macrophage (J774 cell line). This scientific project was done in order to develop a method with this cell line in our laboratory condition for further apoptosis study in the presence of M. LÄS MER
