  1. 1. Exploring electroweak symmetry breaking in the scale-invariant Two-Higgs-Doublet Model

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Erik Rustas; [2023]
    Keywords : Two-Higgs-Doublet Models; 2HDM; Scale-invariance; Baryogenesis; BSM; Baryon Asymmetry; Coleman-Weinberg Potential; Theoretical Particle Physics; Physics and Astronomy;

    Abstract : This thesis investigates the properties of a general scale-invariant Two-Higgs-Doublet Model and its phenomenological consequences with focus on the scalar sector. The concept suggests that introducing more CP-violation, both spontaneous and explicit, may make it possible to meet the Sakharov conditions and account for the Universe's baryon asymmetry.

    Abstract : Millimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. READ MORE

  4. 3. Determination of an Optimum Sector Size for Plan Position Indicator Measurements using a Long Range Coherent Scanning Atmospheric Doppler LiDAR

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Elliot Simon; [2015]
    Keywords : LiDAR; WindScanner; PPI; Sector Scan; Dual Doppler; Remote Sensing; Wind Measurement;

    Abstract : As wind energy plants continue to grow in size and complexity, advanced measurement technologies such as scanning Doppler LiDAR are essential for assessing site conditions and prospecting new development areas.   The RUNE project was initiated to determine best practices for the use of scanning LiDARs in resource assessments for near shore wind farms.

  5. 4. Pc5 Detection in Geosynchronous Particle Data Using Artificial Neural Network

    University essay from KTH/Rymd- och plasmafysik

    Author : Erik Lysell; [2011]
    Keywords : ;

    Abstract : Geomagnetic pulsations are magnetohydrodynamic (MHD) waves in Earth‘s magnetosphere that can be seen as variations in the magnetic and electric fields, but also in particle data. Artificial Neural Network’s (ANN’s) ability to recognize patterns have been used to find Pc5 pulsations in geosynchronous electron flux data from LANL satellites. READ MORE
