  1. 21. Constraining the top-Z coupling using the (ttWj)EW process with the ATLAS experiment : A search for physics beyond the Standard Model

    Författare :Nabila Ahlgren; Jörgen Sjölin; Robert Schöfbeck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; ATLAS; top physics; fysik; Physics;

    Sammanfattning : The Standard Model (SM) of particle physics, having been confirmed by numerous experiments, is one of the most successful theories in physics. It describes all known elementary particles and their interactions through the electromagnetic, strong and weak force. LÄS MER

  3. 22. Maxillofacial cone beam computed tomography (CBCT) : aspetcs on optimisation

    Författare :Ayman Al-Okshi; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CBCT; OPTIMISATION; DOSAGE;

    Sammanfattning : Inom odontologisk såväl som inom medicinsk radiologi sker en snabb utveckling av nya tekniker. Nya metoder för att kunna diagnosticera och följa sjukdomsförlopp över tid introduceras. Cone-Beam Computed Tomography (CBCT) är en sådan ny teknik, som introducerades inom odontologin under sent 1990-tal. LÄS MER

  4. 23. Characterization of Small Antennas & Wireless Devices for MIMO Systems in Rich Isotropic Multipath & Random Line-of-Sight

    Författare :Ahmed Hussain; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO; Rayleigh; reverberation chamber; random LOS; RIMP; LTE; OTA;

    Sammanfattning : The current thesis is about over-the-air (OTA) performance characterization of wireless terminals in rich isotropic multipath (RIMP) environment as well as in pure line-of-sight (LOS) environment while not ignoring the random positions and orientations of the mobile terminals due to randomness of the user. The latest mobile wireless terminals such as iPhone and iPad can be used in any random position and orientation thereby making the received LOS-component toappear as a random voltage at the antenna ports.
