  1. 16. Measuring ammonia: Development and application of measurement techniques for the detection of ammonia

    Master-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Odd Magnar Hole; [2013]
    Nyckelord :images; imaging; PFLIF; Detection; Laser; Two-photon; 2-photon; SCR; LIF; Ammonia; Physics and Astronomy;

    Sammanfattning : Ammonia (NH3) is an important chemical both as a chemical precursor and in its own right. It is therefore of practical importance to be able to visualize ammonia gas especially when ammonia is present in combustion or flue-gas environments. LÄS MER

  3. 17. Determining the spin of the Black Hole in the Active Galactic Nucleus NGC-4395 using X-Ray spectroscopy

    Kandidat-uppsats, KTH/Fysik

    Författare :Celine Weimer; Rasmus Östlund; [2013]
    Nyckelord :;

    Sammanfattning : The micro Seyfert galaxy NGC-4395 hosts a supermassive black hole at its center that actively accrete matter and thus radiates very strongly in the X-ray range. Denoted the active galactic nucleus this thesis focuses on determining its spin. LÄS MER

  4. 18. Spectrum Sensing of acoustic OFDM signals

    Master-uppsats, Kommunikationssystem; Tekniska högskolan

    Författare :Sivakesava Reddy Malkireddy; [2012]
    Nyckelord :OFDM; Autocorrelation; Spectrum Sensing; Cognitive radio; GLRT;

    Sammanfattning : OFDM is a fast growing technology in the area of wireless communication due to its numerous advantages and applications. The current and future technologies in the area of wireless communications like WiMAX, WiFi, LTE, MBWA and DVB-T uses the OFDM signals. LÄS MER

  5. 19. Is old forest like old forest? : patterns in abundance and species number of resident birds in old boreal forest stands in relation to stand structure and landscape context

    Magister-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Ortrud Leibinger; [2011]
    Nyckelord :resident birds; boreal forest; habitat; declining species;

    Sammanfattning : Forest structure and composition may be, dependent on e.g. soil conditions, human impact and forest age, very different, which might result in differences in abundance and species number of resident forest bird. LÄS MER

  7. 20. Simulations of Quantum Black Hole collisions at the LHC with PYTHIA

    Kandidat-uppsats, Högenergifysik

    Författare :Carl Niblaeus; [2011]
    Nyckelord :LHC; black hole; PYTHIA; extra dimensions; symmetry; Planck mass; accelerator; Monte Carlo; simulation; LHC; svart hål; PYTHIA; extra dimensioner; symmetri; Planckmassan; accelerator; Monte Carlo; simulering;

    Sammanfattning : In this bachelor's thesis the concept of microscopical black hole production at colliders is investigated. By using extra dimensional models where the value of the Planck mass can be reduced to the TeV scale, gravity can be made stronger at small distances and the Hierarchy problem can be solved. LÄS MER
