  1. 1. Determination and compensation of magnetic dipole moment inapplication for a scientific nanosatellite mission

    University essay from KTH/Rymd- och plasmafysik

    Author : Csaba Jéger; [2017]
    Keywords : cubesat; magnetic dipole estimation; attitude dynamics; cubesat; magnetisk dipol uppskattning; attityddynamik;

    Abstract : SEAM (Small Explorer for Advanced Missions) is a 3U CubeSat developedat KTH Royal Institute of Technology which will provide highqualityDC and AC magnetic field measurements of Earth’s magneticfield. The measurement system requires extended periods of timeup to 1000 seconds without active attitude control. READ MORE

  2. 2. 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.

  3. 3. 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.

  4. 4. 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

  5. 5. Remote heart rate estimation by evaluating measurements from multiple signals

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Kristoffer Uggla Lingvall; [2017]
    Keywords : heart rate estimation; remote heart rate; heart rate; hr; pulse; pulse detection; remote pulse; photoplethysmography; plethysmography; ppg; rppg; multiple signals; fft; ica; pca;

    Abstract : Heart rate can say a lot about a person's health. While most conventional methods for heart rate measurement require contact with the subject, these are not always applicable. In this thesis, a non-invasive method for pulse detection is implemented and analyzed. READ MORE
