  1. 21. k_S^0, Λ, and ͞Λ, pT spectra in pp collisions at √s = 7 TeV, measured with the ALICE experiment at LHC

    University essay from Lunds universitet/Fysiska institutionen

    Author : Tuva Richert; [2011]
    Keywords : Physics and Astronomy;

    Abstract : This thesis presents a study of L, ¯L, and K0 s particle (generically referred to as V0 particles) production measured by the ALICE experiment located at LHC, CERN, in protonproton collisions at a center of mass collision energy of p s = 7 TeV. The particles are reconstructed via their V0 decay topology, which can be done due to the excellent tracking performance of the Time Projection Chamber detector. READ MORE

  3. 22. Performance Analysis of Selected Cooperative Relaying Techniques

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Muhammad Afaq; Sahibzada Muhammad Faheem; [2010]
    Keywords : Cooperative communication; Relaying techniques; Amplify-and-forward; Decode-and-forward; DtF; S-DtF; MRC;

    Abstract : Recently, cooperative communication has gained significant interest due to the fact that it exploits spatial diversity and provides capacity/performance gain over conventional single- input single-output (SISO) systems. A mobile node with single antenna can cooperate with a nearby mobile node having single antenna in multi-user environment to create the effect of virtual multiple antenna system. READ MORE

  4. 23. Denoising of Complex MRI Data by Wiener-like Filtering in the Wavelet Domain - Application to High b-value Diffusion Weighted Imaging

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Adnan Bibic; [2006]
    Keywords : MRI; Medicine and Health Sciences;

    Abstract : Noise is a well-known problem in many imaging modalities. In magnitude magnetic resonance images, obtained by quadrature detection, the associated Rician distribution of noise constitutes a further complication. This type of noise is especially problematic at low signal-to-noise ratio (SNR) regions. READ MORE

  5. 24. Production of 45Ti using a low-energy accelerator

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Mikael Folkesson; [2004]
    Keywords : Nukleärmedicin; Medicine and Health Sciences;

    Abstract : The purpose of this study was to obtain more knowledge of the parameters affecting the production of 45Ti utilizing the nuclear reaction 45Sc(p,n) 45Ti. Titanium-45 decays by +-decay and E.C. to 45Sc with a half-life of 3,08 h. READ MORE

  6. 25. 90Y-Scintigraphy of small animals A study of imaging parameters

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Melinda Joo; [2003]
    Keywords : Nukleärmedicin; Medicine and Health Sciences;

    Abstract : Yttrium-90 is a pure β-emitting radionuclide with a high energy (Emax = 2.28 MeV) and a short half-life (T½ = 64.1 h). It has shown to be a promising isotope to use in radio-immunotherapy. READ MORE
