  1. 1. Solving ill-posed problems with mollification and an application in biometrics

    University essay from Linköpings universitet/Matematik och tillämpad matematikLinköpings universitet/Tekniska fakulteten

    Author : Emma Lindgren; [2018]
    Keywords : Mollification; regularization; ill-posed problems; biometrics; blood vessel;

    Abstract : This is a thesis about how mollification can be used as a regularization method to reduce noise in ill-posed problems in order to make them well-posed. Ill-posed problems are problems where noise get magnified during the solution process. An example of this is how measurement errors increases with differentiation. READ MORE

  2. 2. Millimeter Wave Antenna Array Calibration and Validation for 5G New Radio Access

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Manuel Jose Lopez Morales; [2018]
    Keywords : Technology and Engineering;

    Abstract : This Master thesis work was performed in Ericsson AB, Lund. It studies and validates two classes of algorithms to be used in mm-wave massive MIMO antenna arrays, for their use in the future 5G mobile communication systems. READ MORE

  3. 3. Short-Wave Infrared Lidar on Atmospheric Aerosols and Insects

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Mariam Andersson; [2017]
    Keywords : Lidar; Scheimpflug; Time-of-Flight; Remote sensing; Atmospheric sensing; Physics and Astronomy;

    Abstract : This thesis focusses on the implementation of two elastic lidar (light detection and ranging) techniques for the monitoring of atmospheric aerosols and insects at short-wave infrared wavelengths. Data acquisition software was developed for a time-of-flight system, housed in the Lund University Mobile Biosphere Observatory (LUMBO), with consideration to the intended entomological application.

  4. 4. Low-Frequency Noise in InGaAs Nanowire MOSFETs

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Christian Mario Möhle; [2017]
    Keywords : Physics and Astronomy;

    Abstract : Low-frequency (LF) noise (1/f as well as random telegraph-signal (RTS) noise) measurements were performed on high-performance InGaAs nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs). 1/f noise measurements at room temperature (RT) show that the dominant noise mechanism is carrier number fluctuations.

  5. 5. Computational sound propagation models: An analysis of the models Nord2000, CONCAWE, and ISO 9613-2 for sound propagation from a wind farm

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jôse Lorena Guimarães da Silva; [2017]
    Keywords : Nord2000; CONCAWE; ISO 9613-2; noise propagation; noise wind turbines.;

    Abstract : The recent goals from some countries to become renewable energy based and reduce carbon dioxide emissions have caused the wind industry to grow. Together, the size of the wind farms and the noise emission have grown, while the noise emission regulations have to be fulfilled. READ MORE
